Your physician wants you to have an endoscopy procedure, and you have questions. At Dr. Glenn Madokoro's gastroenterology office in Newport Beach, CA, endoscopy is one of his most reliable--and easy--diagnostic procedures. Read here answers to frequently asked questions about it so you feel fully informed.

What is an endoscopy?

An endoscopy is a diagnostic procedure that introduces a thin, lighted tube down the throat and into the esophagus and upper stomach. Endoscopy gives the Newport Beach GI physician real-time still and video images of your upper gastrointestinal tract. Also, it allows him to take tissue samples for biopsy and to remove growths or galls stones, or to repair ulcers, explains Healthline.

Why do I need one?

Typically, your doctor wants to understand why you are having GI symptoms such as pain, difficulty swallowing, heartburn or other issues. Also, Dr. Madokoro may wish to track your progress on ongoing problems such as Barrett's Esophagus or a hiatal hernia.

How long does the procedure take?

It takes about 30 to 45 minutes.

Does it hurt?

No, it doesn't hurt. You will be sedated and the back of your throat, anesthetized. Patients experience no gagging sensation or pain.

How long will I be in recovery?

Because endoscopy is an outpatient procedure, you'll go home the same day escorted by an adult relative or friend. For the balance of the day, you should take it easy, and avoid driving or operating machinery of any kind. You can return to your normal activities the next day.

When will I get my test results?

After your endoscopy, Dr. Madokoro will visit you in recovery to review his findings. If he took biopsies, you can get your results by contacting our Newport Beach office in about a week.

What is capsule endoscopy?

This high-tech procedure involves swallowing a tiny camera encased in a biocompatible capsule. It resembles a vitamin pill. Until it passes naturally from the body through the GI tract, the capsule sends real-time images to a receiver the patient wears. Then, the doctor views these images in the office. Usually, capsule endoscopy helps with the diagnosis and treatment of problems such as Crohn's Disease or cancer.

Concerned about colon polyps? Here’s what you need to know.

Maybe you just heard from a friend that they detected colon polyps during their last colonoscopy. Now you’re wondering if this is something that you should get done. Everyone should start getting routine colonoscopies at least once every ten years by the time they reach 50 years old (our Newport Beach, CA, gastroenterologist Dr. Glenn Madokoro may recommend earlier if you are at high risk for colorectal cancer or polyps). Here are answers to the top questions we get about colon polyps.

Are colon polyps cancerous?

While polyps are usually not cancerous, some do have the ability to turn into cancer, which is why our Newport Beach, CA, gastroenterologist will remove the polyps during your colonoscopy as a preventive measure.

Do colon polyps cause symptoms?

Polyps are actually surprisingly common, but many people don’t even realize that they have them. In fact, polyps rarely cause symptoms. This is another reason why everyone (both men and women) should get routine colonoscopies; however, in some cases, patients with colon polyps may experience,

  • Blood in the stool
  • Black stools (if the polyps are bleeding)
  • Lightheadedness and fatigue
  • Anemia (caused by bleeding)
  • Unexplained abdominal pain

What puts someone at risk for developing colon polyps?

This is something that can develop in anyone; however, you may be more likely to deal with polyps if you are over 50 years old, you have a family history of colorectal cancer or polyps, you’ve been diagnosed with inflammatory bowel disease (e.g. Crohn’s disease; ulcerative colitis) or you are obese. Those who smoke or have uncontrolled type 2 diabetes are also at risk.

How are colon polyps detected?

The most common procedure used to detect and remove polyps is a colonoscopy. This procedure is performed right here in our office under conscious sedation. Once the sedation has taken effect, we will guide the scope into the rectum and through the colon. If polyps are detected during the procedure, we also have special tools that can be inserted into the scope to remove the tissue. Most colonoscopies take anywhere from 20-30 minutes but may take longer if we need to remove polyps.

If you have questions or concerns about colon polyps, or if you need to schedule a colonoscopy at our Newport Beach, CA, practice, call us today at (949) 548-8800.

The Difference Between Endoscopy vs. Colonoscopy

Both colonoscopy and endoscopy are non-surgical procedures performed by a gastroenterologist. They also both use a device known as an endoscope, which has a fine, flexible tube with a light and camera attached. To enable to doctor to view the inside of parts of your digestive tract. Dr. Glenn Madokoro is a gastroenterologist in Newport Beach, CA. He provides endoscopy and colonoscopy services.

What is an Endoscopy?

Usually, this term refers to an examination of the upper part of your digestive tract. Newport Beach patients who undergo an endoscopy will have an endoscope passed into their mouth and down their throat into their esophagus. This enables the doctor to view the esophagus, stomach, and duodenum (upper small intestine). Typically, you will not have to make special preparations for an endoscopy, although your stomach should be empty, so you should not eat or drink anything for six hours prior to the procedure.

What is a Colonoscopy?

During a colonoscopy, an endoscope is passed into your rectum and through to your colon (large intestine). You will need to prepare for a colonoscopy in the following ways:

  • Three days prior to your colonoscopy, you should only eat foods that are low in fiber.
  • This dietary regime should be continued on the second day prior to your procedure.
  • The day before your procedure you should switch to a clear liquid diet.
  • The evening before your procedure you will drink the first half of your prescription laxative drink.
  • On the morning of your procedure, you will drink the second half of your laxative drink.

Both procedures typically take around 20-40 minutes. You will need someone to drive you home after a colonoscopy. If you had any tissue samples removed during wither procedure, your doctor will contact you within 14 days when the results are back from the lab.

If you would like to schedule an appointment for a colonoscopy or an endoscopy in Newport Beach, CA, call Dr. Madokoro at (949) 548-8800.

Tags: Endoscopy  

An endoscopy is a simple nonsurgical procedure commonly utilized for inspecting the digestive tract. It entails the use of an endoscope, which is a malleable, thin tube with a tiny camera and light attached at the tip so that your doctor could see images of your digestive tract projected on a display monitor. It can spot precancerous and benign polyps and cancerous or malignant tumors.

Likewise, it can determine the presence of inflammation, ulcers, and other kinds of damage to your stomach or intestine walls. Additionally, an upper GI (gastrointestinal) endoscopy could spot the cause of swallowing issues, chest pain, and heartburn. In certain cases, an endoscopy may also be used for removing objects or polyps and taking tissue samples for evaluation.

Endoscopy comes in different types and it will be up to your gastroenterologist, Dr. Glenn Madoroko of Glenn D Madoroko, MD, in Newport Beach, CA, to determine which one will suit you best.

The Different Types of Endoscopies

During a standard upper endoscopy, your doctor will pass an endoscope through your mouth, throat, and esophagus to enable him to see into your esophagus, the small intestines’ upper portion, and your stomach. Similarly, an endoscope could be passed into the colon or large intestine via the rectum to inspect that part of the intestine.

Likewise, an ERCP, or endoscopic retrograde cholangiopancreatography, will enable your doctor to take images of the gall bladder, pancreas, and associated structures. It can also be utilized for biopsies and placing stents. In addition, EUS, or endoscopic ultrasound, combines ultrasound and endoscopy to obtain information and images about different digestive tract structures.

When is an Endoscopy Recommended?

Your gastroenterologist in Newport Beach, CA, may recommend an endoscopy for assessing the following:

  • Abdominal pain
  • Swallowing problems
  • Ulcers
  • Bleeding in the digestive tract
  • Gastritis
  • Bowel habit changes such as sudden and/or consistent diarrhea or constipation
  • Colon growths or polyps

Depending on your reason for undergoing an endoscopy, your gastroenterologist may also utilize an endoscopy to take a sample of suspicious tissue (biopsy) that should be assessed. Likewise, an endoscopy can be used for treating digestive tract issues. For instance, aside from spotting active bleeding from ulcers, an endoscope can also carry devices that could help halt the bleeding. Furthermore, gallstones that have accumulated in the bile duct could be taken out through endoscopy.

In 2019, about 145,600 men and women in the U.S. received a colorectal cancer diagnosis. Although the condition mainly affects older adults, there's a rising incidence in younger individuals. When detected early, it's often curable. Prevention is possible using an imaging test that looks for abnormalities in the lining of the large intestine. At his Newport Beach, CA, office, Dr. Glenn D. Madokoro recommends a colonoscopy to healthy patients with an average, increased, or high risk of developing colon cancer or dangerous polyps. If you're under 45 and have a family history, schedule a consultation with our gastroenterologist to learn when you should undergo this procedure.

What is a Colonoscopy?

During this screening test, Dr. Glenn D. Madokoro uses an instrument called a colonoscope. It's the size of a thin, flexible tube with a lens and light source that allows him to view images on a video monitor. For the outpatient procedure conducted in our Newport Beach, CA, office, there are different sedation options that we'll address amidst your initial consultation. During, the doctor gently inserts this small camera into the anus, gradually pushing it further into the rectum and colon to search for abnormal tissue. If something is a cause for concern, he may take a biopsy sample or remove polyps that might be pre-cancerous or cancerous.

When Should You Get a Colonoscopy?

Nowadays, you're never too young for a colonoscopy, and increased awareness, as well as screening, could save up to 30,000 lives each year. Although early stages of colorectal cancer don't typically have any symptoms, a doctor may recommend this procedure when the following are present:

  • Abdominal discomfort or bloating
  • Dark patches of blood in the stool
  • Unexplained fatigue or weight loss
  • Bleeding or cramping in the rectum
  • Inability to pass a bowel movement

Colorectal cancer is the third leading cause of cancer-related fatalities in the United States. Dr. Glenn D. Madokoro is trained and experienced to identify symptoms early and create an effective treatment plan aimed at saving lives.

How an endoscopy from your gastroenterologist in Newport Beach, CA, can protect your health

An endoscopy is a simple procedure that can very effectively protect your health. When you undergo an endoscopy, it helps your gastroenterologist detect any serious medical conditions affecting your upper digestive system. Dr. Glenn D. Madokoro in Newport Beach, CA, offers a wide range of gastroenterology services, including endoscopies, to help keep you healthy.

More about endoscopy

To perform an endoscopy, we use an endoscope, which is an ultra-thin catheter with a camera attached to one end. The endoscope is inserted in your mouth and guided down into your esophagus, down to your duodenum and stomach. The camera allows your gastroenterologist to view the tissue of your upper digestive system, looking for any abnormalities, such as growths and irritated tissue.

Endoscopy treatment is very effective at diagnosing gastroesophageal reflux disease or GERD, ulcers, anemia, gastrointestinal cancers, and celiac disease. During an endoscopy, it is also possible for your gastroenterologist to take a tissue sample for biopsy in order to confirm an exact diagnosis. Endoscopies provide an opportunity for early diagnosis, which can lead to early treatment to get you back to health faster, and with a better outcome.

You may need an endoscopy if you experience any of these signs and symptoms:

  • Continuous, chronic abdominal pain
  • Recurrent diarrhea, nausea, and vomiting
  • Problems swallowing or chronic hoarseness
  • Gastrointestinal bleeding

An endoscopy is performed on an outpatient basis. You will be sedated before the procedure to help you relax, and so you must bring someone with you to drive you home afterward. Avoid taking any blood-thinning medications or NSAIDS before treatment and don’t eat or drink anything from 4 to 8 hours before your procedure.

Endoscopies are an easy, comfortable way to protect your health. They are a vital diagnostic tool to help your gastroenterologist give you the most accurate diagnosis and determine treatment. To learn more about endoscopies and how they can help you, call Dr. Glenn D. Madokoro in Newport Beach, CA, today at (949) 548-8800.

Tags: Polyps  

Polyps are small tissue growths that usually appear in the lining of the colon (large intestine), but can also develop in other parts of the polypbody, as well. While polyps are usually benign (non-cancerous), they can also be an early warning sign of colon cancer if detected during an endoscopic procedure known as a colonoscopy. Read on to learn more, and contact Dr. Glenn Madokoro, your gastroenterologist in Newport Beach, CA, if it's time for you to schedule a colonoscopy


Colonoscopy and Polyp Detection in Newport Beach, CA

Polyps don't cause symptoms, so you will not be able to tell if you have them without an exam. In general, the American Cancer Society recommends that people begin screenings for colon cancer at age 50, as the risk for colorectal cancers tends to increase with age. However, some people may have to begin screenings earlier than that depending on their personal/family history and risky lifestyle factors such as obesity and smoking.


How GI Doctors Screen for Polyps

There are several tests available depending on your situation and medical history. For instance, a sample of your stool may be tested for blood, or diagnostic imaging test may be administered. Some of these include:

  • CT scan
  • Sigmoidoscopy
  • Colonoscopy

Polyps are usually small and asymptomatic, but you should let your doctor know right away if you experience any of the following symptoms:

  • Unexplained changes in bowel movements
  • Blood in your stool
  • Abdominal cramping (larger polyps can create blocks in the colon)
  • Unexplained weight loss or anemia

Other factors that may increase the risk of colon polyps include underlying health conditions, such as type 2 diabetes and inflammatory bowel syndrome.

You've probably seen the television ads for colon screening. Maybe you've talked to friends about colonoscopies. If getting a colonoscopy is something you are considering, you probably have questions. Dr. Glenn Madokoro can be your colonoscopy expert in Newport Beach, CA.

What is a colonoscopy?

A colonoscopy is a procedure during which your doctor uses a camera instrument called a colonoscope to see direct imaging of your entire colon, and perform a thorough exam. The procedure allows the doctor to see any irregularities in your colon, and serves as a colon cancer screening. Colonoscopies are a proven method for early detection and treatment of colon cancer.

When should I get a colonoscopy?

The American College of Gastroenterology (ACG) recommends that both men and women start scheduling colonoscopies at age 50. For people of African descent, age 45 is recommended for your first colonoscopy.

If you have a parent or sibling who has been diagnosed with colon cancer, you should get your first screening 10 years earlier than their age at diagnosis, or at age 40 - whichever is younger.

Is a colonoscopy painful?

Typically colonoscopies do not cause pain. Patients are sedated during the procedure, and shouldn't feel anything while the colonoscope is checking out your colon.

What is colonoscopy preparation like?

You may have heard rumors about what the preparation is like for a colonoscopy procedure. It is important for your colon to be clean so your doctor is able to identify any irregularities that may exist.

Most doctors will prescribe a large amount of liquid called polyethylene glycol (PEG) that causes several hours of diarrhea and clears the colon. Your doctor in Newport Beach may also prescribe oral laxatives to help with this process. There are other methods of preparation as well. You will work directly with your doctor to determine which method will work best for you personally.

Millions of Americans suffer from acid reflux and GERD, or up to 30% of the population according to the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Glenn Madokoro, a gastroenterologist in Newport Beach, CA, offers endoscopy and other diagnostic and treatment options for digestive issues and disorders.

Endoscopy and Gastroenterology Services in Newport Beach, CA

An endoscopy is an outpatient procedure and is performed with a thin, small tube attached to a light and camera that allows the doctor to examine the esophagus, stomach, and the opening of the small intestine. The images allow the gastroenterologist to look for abnormalities and in some cases to remove tissue samples and growths for biopsy and further testing.

When to See a Gastroenterologist

Diagnostic imaging tests like endoscopy are recommended by a physician if they suspect that you may be suffering from a condition like chronic acid reflux, inflammation, bleeding, or if you have high-risk factors for digestive cancers. While a little heartburn and acid reflux are normal from time to time, ongoing and repetitive digestive discomfort and pain may be a sign of a problem. You may need to schedule an appointment with a gastroenterologist if you are experiencing the following symptoms:

  • Chronic heartburn
  • Constipation
  • Diarrhea
  • Acid reflux
  • Abdominal pain
  • Changes in bowel movements
  • Blood in stool

As a rule, pay attention to new or unexplained symptoms that don't resolve on their own after a few days, or go away and come back. Seek immediate medical treatment if you experience symptoms along with fever or signs of infection, or after an injury or trauma.

A colonoscopy screens patients for colon cancer. Recommended for people ages 50 and older, this minimally-invasive test looks for Ulcerative Colitisirregularities in the bowels, takes samples for biopsies, and uncovers the reasons for chronic diarrhea, ulcerative colitis, and other problems of the lower GI tract. In Newport Beach, Dr. Glenn Madokoro is your go-to gastroenterologist for a colonoscopy. Is it time for you to have one?


What to expect

During a screening colonoscopy our Newport Beach practice, your gastroenterologist will use a thin lighted tube to inspect the interior of your lower Gi tract, including the ascending colon, transverse colon, descending colon, and rectum. He takes real time and still images of the lining of the bowels and looks for problems such as diverticulitis and, more importantly, cancerous growths and polyps.

Many individuals over the age of 50 have benign and precancerous polyps. While these lesions themselves are not necessarily cancerous, some may become malignant over time. In fact, all colon cancer arises from polyps.

Dr. Madokoro performs a colonoscopy in about 45 minutes with the patient positioned on their left side. Typically, patients are sedated so they can respond to simple commands but feel very relaxed or even drop off to sleep. You should also know that this GI test is painless. In fact, most patients say that bowel prep the day before the procedure is the most difficult part of it. To prepare, you'll consume only clear liquids and take a large volume of cathartics to thoroughly cleanse the large intestine.

Finally, after your test, your gastroenterologist will review his findings with you. Biopsy results may take a week. You'll be driven home by a friend or loved one and resume your usual activities the next day.


Get Peace of mind

If you're over 50 and you know that it's time for your screening colonoscopy, call Dr. Glenn Madokoro for an appointment. You'll receive complete prep and aftercare instructions so that you know what to expect. Phone (949) 548-8800 today!

How your gastroenterologist in Newport Beach, CA, can help with colon issues

Many people would rather not talk about colon issues, but it is an important topic. One of the more frequent issues affecting the colon is polyps. If you are dealing with this issue, Dr. Glenn D. Madokoro in Newport Beach, CA, can help!


More about Polyps

Polyps are more common than people realize, and the older you get, the more susceptible you are to their formation. The average person who is 60 years old has a 25% chance of developing a colon polyp. Formation of polyps may be related to having a high fat and low fiber diet, and there may also be a genetic component.

Although hyperplastic polyps are non-cancerous, adenomas, another type of polyp, can be an early sign of colon cancer. Polyps need to be removed for biopsy to determine whether they are benign (non-cancerous) or potentially an early sign of cancer.

Because you become more susceptible to colon polyps as you get older, a colon cancer screening via colonoscopy is recommended by the time you reach 50 years old. During the colonoscopy procedure, polyps and other abnormal tissue can be identified and removed for later biopsy.

You should schedule a colonoscopy if you have a family history of colon polyps or colorectal cancer. There are also several other indications that a colonoscopy could be beneficial for you. Contact your gastroenterologist if you are experiencing:

  • Chronic abdominal pain
  • Chronic constipation or diarrhea
  • Dark stools, which could indicate blood in your stool


Concerned? Give Us a Call Today!

Both colon polyps and colon cancer are common conditions, which is why colon cancer screening and colonoscopies are critical to your continuing good health. According to the American Cancer Society, colorectal cancer is the third leading cause of cancer deaths.

Early diagnosis is critical as it leads to more effective treatment and a better outcome for you. Call Dr. Glenn D. Madokoro in Newport Beach, CA, today at (949) 548-8800 to protect your health!

How To Prepare For an Endoscopy

To have an accurate endoscopic procedure, you need to avoid eating or drinking 4 to 8 hours before your procedure, and if you are taking blood thinning medications or NSAIDS, you need to stop taking them before treatment. Your gastroenterologist may give you a sedative before your procedure to help relax you. For this reason, it’s important to bring someone with you who can drive you home after your endoscopy.

What Happens During Your Procedure

An endoscopy utilizes an endoscope, a thin, flexible tube with an attached camera at the end. The endoscope is inserted into your throat, dilating your esophagus to allow your doctor to better view its structures and access your upper digestive system. During the endoscopy, your doctor can also remove abnormal tissue or polyps for biopsy. Endoscopies are well tolerated, and you may even fall asleep during the procedure.

ColonoscopyColon cancer threatens 150,000 Americans annually, says the American Cancer Society. In Newport Beach, CA, your gastroenterologist, Dr. Glenn Madokoro, recommends routine cancer screening by colonoscopy, emphasizing early detection and better cure rates for this potentially deadly disease. Learn about this accurate procedure and how often the experts say you should have it.

How colon cancer happens

Colon cancer affects the large intestine, the long, highly innervated and vascularized tube which runs from the small intestine to the rectum and anus. Responsible for absorbing water and certain nutrients, the colon also helps you eliminate solid waste.

Unfortunately, cancer can plague many sites in the body, including the large intestine. While typical symptoms of colon cancer can include pain, bloating, constipation, diarrhea, and weight loss, many times people exhibit few to no symptoms, particularly in the earliest stages of the disease.

Harvard Health reports that colon cancer may begin with small noncancerous lesions called polyps or adenomas. While these small benign tumors do not always develop into cancer, many do. That's why examination by routine colonoscopy in Newport Beach is so important.

What is a colonoscopy?

This in-office or in-hospital procedure examines the lining, or internal structure, of the large intestine. Your gastroenterologist inserts a small diameter lighted tube into the anus and through the entire length of the colon. Live video feed allows him to look at the colon, detecting abnormalities such as cancer, adenomas, and other issues which cause chronic diarrhea, pain, and more. While polyps do not always become cancerous, says Harvard Health, all colon cancer proceeds from polyps. So, routine screening is vital.

During a colonoscopy, you will be sedated and positioned on your side. During the test, you will experience no pain but may feel some mild pressure or cramping.

Dr. Madokoro will look at your colon and take pictures at certain junctures and of any area which he feels requires closer examination. If he sees any polyps, he will remove them via cautery (heat) or a snare mechanism, and the tissue will be biopsied. You will remember little or even nothing of your test afterwards, and a responsible adult must escort you home.

How often should you get one?

Aside from some individuals who have a genetic predisposition to polyps, most people should begin routine colon screening at age 50. With no evidence of polyps, Dr. Madokoro will advise a repeat procedure in 10 years. With polyps which are noncancerous, he will recommend every five to 10 years.

After age 75, follow your doctor's recommendation for repeat screening tests. After 85, you will not receive routine colonoscopies but only on a case by case basis, says the American College of Gastroenterology.

Tags: Polyps  

Polyps are non-cancerous (benign) growths usually found in the lining of the colon. Although they are typically harmless and do not alwayspolyps cause symptoms, colon polyps can sometimes become cancerous, especially if you have a family history or other risk factors for colon cancer. Dr. Glenn Madokoro, a gastroenterologist in Newport Beach, CA, offers colonoscopy screenings for polyp and colon cancer detection.

Polyp Detection and Treatment in Newport Beach, CA

A polyp is a cluster of excess cells that form in the colon or rectum. Anyone can develop polyps and they tend to become more common with age, but some people are at greater risk, and they can develop in younger people as well. In some cases, polyps may cause noticeable symptoms, including:

  • Pain or abdominal cramps if the polyp is large enough to cause a blockage or obstruction in the bowel
  • Bleeding from the rectum (there are several factors that can cause bleeding, ranging from hemorrhoids to colon cancer. If you experience persistent and ongoing bleeding with bowel movements, schedule an appointment with a gastroenterologist as soon as possible)
  • Chronic diarrhea or constipation/unexplained changes in bowel movements lasting longer than a week

Polyp Causes and Risk Factors

You may be more likely to develop colon polyps under the following circumstances:

  • Are over age 50
  • Have a family history of polyps or colon cancer
  • A sedentary lifestyle low or absence of physical activity and regular exercise
  • Obesity/being overweight
  • Diets high in red and processed meats
  • If you have diabetes, Crohn's disease, or ulcerative colitis
  • Tobacco use

The American Cancer Society recommends that healthy adults begin routine colon cancer screenings by age 50, but individuals with known risk factors may need to begin screenings earlier. Polyps are usually diagnosed through a colonoscopy or a procedure known as a flexible sigmoidoscopy, or through a stool test. If polyps are detected, they are often removed by a polypectomy (tissue is removed with forceps) or minimally invasive laparoscopic surgery. Lifestyle modifications like diet and exercise are also recommended to help maintain a healthy weight and lower your risk of polyps and other health problems.

Along with aging comes the responsibility to take your health by the horns, seeking out preventative care and ensuring that your body colonoscopykeeps up with your mind. A common and important procedure for people over 50 is a colonoscopy. But what does a colonoscopy search for and when does it become necessary? Find out more about the why and when doctors recommend colonoscopy with Dr. Glenn Madokoro at Newport Beach Gastroenterology in Newport Beach, CA.

What is a colonoscopy? 
A colonoscopy is a preventative procedure which scans the colon for a variety of medical reasons. The procedure itself uses a long, thin tube, called a colonoscope, inserted through the rectum into the colon. The colonoscope has a camera on the end and is just wide enough to thread specialized, miniature tools through to take biopsies or other tasks.

Why did my doctor recommend a colonoscopy? 
According to the American Cancer Society, people over the age of 50 with an average risk of developing colon cancer should have a colonoscopy every 10 years. In addition to these regular screenings for colorectal cancer, your doctor may also suggest a colonoscopy to investigate symptoms of distress like abdominal pain, blood in the stool, diarrhea, abnormalities on imagining tests like x-rays, or a sudden change in your bowel habits.

What can I expect during a colonoscopy treatment? 
Prior to your treatment, your doctor will ask you to fast, drink plenty of clear liquids, and take laxatives to clean out the bowels before your procedure. Your doctor will use sedatives to make you fall asleep during your procedure. Due to the sedatives, you will also need someone there with you to drive you home. Your doctor inserts the colonoscope and uses its light and camera to examine the lining of your colon, searching for abnormalities like polyps. If your doctor finds a polyp, they may take a biopsy with specialized tools.

Colonoscopy in Newport Beach, CA
Colonoscopy is a powerful and effective preventative procedure. Colorectal cancer grows slowly over a long period of time, making it highly treatable if caught in its earliest stages. This makes regular colonoscopies highly beneficial to your long-term health. For more information on colonoscopy, please contact your Newport Beach, CA gastroenterologist, Dr. Glenn Madokoro, at Newport Beach Gastroenterology.

Tags: Endoscopy  

Endoscopies offer a minimally invasive way to diagnose conditions and diseases that can affect the upper part of your gastrointestinal endoscopytract. Newport Beach, CA, gastroenterologist Dr. Glenn Madokoro shares a few reasons that you may need an endoscopy and explains the process.

What is an endoscopy?

Endoscopies are used to view the lining of your upper gastrointestinal tract via a small camera attached to a lighted scope. The camera transmits images to a digital monitor, allowing your gastroenterologist to detect and possibly treat the source of your gastrointestinal issues.

How are endoscopies performed?

Prior to your procedure, you'll receive anesthesia or a sedative. As a result, you probably won't remember anything about the endoscopy. The procedure begins with the insertion of the endoscope into your mouth. The scope is gradually passed through your throat, esophagus, stomach and the upper part of your small intestine. As the camera passes through the tract, your gastroenterologist looks for bleeding, inflammation, lesions or other issues that could cause your symptoms. During the endoscopy, he may take biopsies of the lining of your gastrointestinal tract, cauterize bleeding, remove growths, open strictures or perform other treatments. The entire procedure is usually completed in around 30 minutes.

Why would I need an endoscopy?

Endoscopies are a valuable diagnostic tool that can help your gastroenterologist diagnose a variety of conditions, including gastroesophageal reflux disorder (GERD), blockages, narrowing of the esophagus, gastroesophageal reflux disorder (GERD), ulcers, celiac disease, esophagitis, gastritis and other diseases and conditions.

You may need an endoscopy periodically if you've already been diagnosed with a gastrointestinal disease or condition or if you mention any of these symptoms during your visit to our Newport Beach office:

  • Pain
  • Frequent heartburn
  • Bleeding
  • Unexplained weight loss
  • Nausea
  • Vomiting
  • Difficulty swallowing

What is the preparation and recovery process like?

You'll probably be asked not to eat or drink for eight hours before your procedure. After the endoscopy, you will be observed for an hour or two to ensure that you've fully recovered from the sedative or anesthetic. Because the sedative or anesthetic may affect your judgment for the rest of the day, you'll need to ask a friend or family member to drive you home. Your throat may feel a little sore for a day, but the pain should be mild and will soon disappear. Your results will be discussed with you immediately after your procedure, although you'll have to wait to receive the results of biopsies.

Do you suffer from pain, heartburn or other gastrointestinal problems? Call Newport Beach, CA, gastroenterologist Dr. Glenn Madokoro at (949) 548-8800 to schedule an appointment.

Tags: Polyps  

Are you suffering from polyps?polyps

Dr. Glenn Madokoro, your Newport Beach, CA, gastroenterologist, is an expert when it comes to detecting polyps so if you're in need of a colonoscopy, here are some things you may want to know beforehand.

What are polyps?

Polyps are a noncancerous growth that can be found in the lining of the bowel. They occur in your gastrointestinal tract but are found most commonly in the colon. Polyps vary in size and look like bumps or mushrooms protruding from the bowel.

Screening methods are important and necessary to detect polyps. Your Newport Beach gastroenterologist may recommend a colonoscopy to detect these polyps so that he can remove them.

What causes them?

Polyps are common among adults who are estimated to be an average of 60 years old. The cause of polyps is unknown, but experts think it may be due to a high-fat and low-fiber diet, or genetics.

What types of polyps are there?

There are two common types of polyps:

  • The hyperplastic polyp, which isn't a cancer risk.
  • The adenoma is thought to be the origin of many colon cancers.

How often do I need a colonoscopy?

Cleaning the surface of your colon is important. Your next colonoscopy will be set by your doctor, but the timing he sets will depend on the following factors:

  • The number of polyps and the size of the polyps. If they are small, then your doctor will schedule repeating a colonoscopy in three to five years. If, however, they are large and flat, then your doctor may recommend you repeat the colonoscopy in a few months.
  • The type and quality of the polyps' tissue

For more information on polyps, colonoscopies and how to remove polyps, you need to contact your Newport Beach, CA, doctor, Dr. Glenn Madokoro, at (949) 548-8800 today!

If you're age 50 or older, you know that a screening colonoscopy appears on your "to do" list. If your heredity and current health status


indicate you're at low risk for developing colon cancer, your gastroenterologist in Newport Beach, CA may ask you to repeat the test every 10 years. However, some conditions require more frequent screening or a follow-up colonoscopy. Follow-up of this very accurate diagnostic test is much like your original screening. Find out the reasons why it's performed from Dr. Glenn Madokoro.

Is colon cancer a real threat?

Yes, it is, especially as your age advances beyond 50. The American Cancer Society says that undetected, colon cancer will kill 50,000 Americans this year alone. That's why prophylactic testing is so important. If detected in its earliest stages, colon cancer can be cured.

Your Newport Beach gastroenterologist will help you determine what your interval should be between your initial screening colonoscopy and your follow-ups. Many adults require follow-up after 10 years because their intestinal mucosa showed no areas of concern.

If however, your exam reveals abnormalities such as diverticulum, small pouches or indentations which form in the walls of the large intestine, or polyps, growths that can be benign or precancerous (adenomas), you likely will need more frequent colonoscopies.

What happens during a follow-up colonoscopy?

Physicians also call this procedure a surveillance colonoscopy because it watches for changes in previously found abnormalities. Dr. Madokoro is well-known for his slow and careful search through the large intestine using a lighted and video-monitored scope.

To begin your procedure, you are given a tranquilizer, such as Valium, to relax you. You rest on one side and the doctor gently inserts the thin, flexible instrument through the rectum. Some patients drift off to sleep during the test and may remember very little of the experience afterward.

As the doctor advances the scope, he searches for polyps and removes them for biopsy if he encounters any. Polyps may be excised with a tiny electrical current (burn fulguration) or with a small loop of wire (snare polypectomy). Dr. Madokoro carefully looks through the entire length of the colon to ensure he has retrieved all polyps.

Don't worry; be informed

Whatever the reason is for your follow-up colonoscopy in Newport Beach, CA, rest assured it is an excellent tool in keeping you and your colon healthy. If it's time for your first colonoscopy or for your follow-up test, please contact Dr. Madokoro's staff for an appointment. Call today: (949) 548-8800.

Endoscopy Procedure Types

Individuals may need an endoscopy in Newport Beach for a variety of reasons including:

  • Digestive tract bleeding
  • Changes in bowel habits
  • Growths or polyps inside the colon
  • Ulcers
  • Gastritis
  • Difficulty swallowing
  • Unexplained stomach pain

  1. Colonoscopy: This procedure tests for colorectal cancer. It uses a colonoscope that is inserted into the rectum. A gastroenterologist can examine the lining of the large intestine (colon) for any abnormalities.
  2. Upper Endoscopy: This procedure allows a doctor to examine the lining of the esophagus, duodenum, and the stomach. It is often used because it is more effective than x-rays to detect any inflammation, tumors or ulcers in the area.
  3. Capsule Endoscopy: This procedure helps the doctor to evaluate the small intestine, a part of the bowel that isn’t reached with a traditional colonoscopy or upper endoscopy. The most common reason is to search for a cause of bleeding. It can also be used to detect polyps, Crohn’s disease, tumors or even ulcers in the small intestine.

Tags: Capsule Endoscopy  

A capsule endoscopy is a procedure allowing gastroenterologists to view and examine the interior middle portion of the gastrointestinal capsule endoscopytract. This area of the gastrointestinal tract includes three sections of the small intestine that cannot be accessed through a traditional colonoscopy or endoscopy. Capsule endoscopies can help determine the cause of bleeding in the small intestine and can be used to detect polyps, tumors and ulcers. Dr. Glenn Madokoro performs capsule endoscopies in Newport Beach, CA.

Capsule Endoscopy Procedure

The capsule endoscopy procedure is performed with a small video camera about the size of a typical pill or capsule. The patient actually swallows this capsule so it can travel down to the small intestine and take pictures of the intestinal lining. During the procedure, the images are sent to a device worn outside the body. After the procedure, the capsule containing the tiny video camera will finish passing through the intestines and be excreted. The entire procedure lasts about eight hours. Extensive physical activity should be avoided immediately afterward.

Preparing for the Procedure

It is important to have an empty stomach during the capsule endoscopy. No food or beverages should be consumed twelve hours prior to the procedure. Prescription or over-the-counter medications might also need to be halted during this time. Let the gastroenterologist know in advance if you are taking any medications so the doctor can determine if those medications might present potential problems. Overall, having a capsule endoscopy done by your Newport Beach gastroenterologist is a straightforward procedure that can detect various problems.

If you need to undergo a capsule endoscopy in the Newport Beach, CA, area, Dr. Madokoro can help. He has extensive experience performing capsule endoscopies and other similar procedures. To find out if you might benefit from having a capsule endoscopy performed, schedule a consultation with Dr. Madokoro by calling (949) 548-8800.

Learn about what services your gastroenterologist, Dr. Glenn Madokoro, at Newport Beach, CA, provides and what he can do for you.

What is a gastroenterologist? 
Gastroenterology is a branch of internal medicine focusing on the diagnosis and treatment of conditions affecting the digestive system, including the esophagus, stomach, small intestine, large intestine, and biliary system. Gastroenterologists have extensive training and education in this field, such as having knowledge of how food moves through the gastrointestinal tract. Gastroenterologists undergo at least 13 years of education, training, residency, and fellowship before becoming Board Eligible and, ultimately, Board Certified.

What can my gastroenterologist do for me? 
Gastroenterologists specialize in diagnosing and treating symptoms of gastrointestinal conditions, including:

  • gallbladder disease
  • cancer
  • constipation/diarrhea
  • hemorrhoids
  • upset stomach/nausea/vomiting
  • unexplained weight loss
  • colon disease
  • ulcers
  • liver disease

Gastroenterology in Newport Beach, CA
Your doctor may use several techniques or tests to investigate your symptoms, including:

  • Colonoscopy: This important procedure uses a long, thin hose to investigate the lower digestive system and search for the presence of cancerous or pre-cancerous symptoms. Routine colonoscopy to screen for colorectal cancers is recommended for patients 50 years and older.
  • Polyp Detection: Polyps are pre-cancerous growths which occur in the digestive tract. Finding and removing polyps early can help keep you and your digestive tract healthy.
  • Endoscopy: While a colonoscopy investigates the lower digestive tract, an endoscopy investigates the upper half. A long thin tube inserted orally allows your doctor to see the esophagus, stomach and a portion of the small intestine.
  • Esophageal Dilation: This procedure stretches narrowed parts of the esophagus to help make swallowing easier for patients who experience scarring due to conditions like acid reflux.

Gastroesophageal reflux disease, or GERD, occurs when stomach acid flows back into your food pipe (esophagus). Most individuals can manage the discomfort of GERD with over-the-counter medications and lifestyle changes. But some patients may need stronger medicines or surgery to reduce symptoms.

3. Ulcerative Colitis

Ulcerative colitis is an inflammatory bowel disease that causes ulcers and inflammation in your digestive tract. Symptoms include abdominal pain, diarrhea and bleeding from the rectum. Treatments for this condition consist of over-the-counter medicines for diarrhea and prescription medicines that reduce the body's immune response.

Having GI distress? Then find out if an endoscopy could give you the answers to your stomach issues.

There are many symptoms that may warrant a trip to see our Newport Beach, CA gastroenterologist, Dr. Glenn Madokoro. An endoscopy endoscopyis a handy diagnostic tool for being able to detect the cause of symptoms such as abdominal pain, heartburn, nausea, gastrointestinal bleeding or difficulty swallowing. Find out more about an endoscopy and how it might be able to give you the answers you’ve been looking for.

An upper endoscopy is an outpatient procedure in which our Newport Beach GI doctor will place a thin flexible scope into the upper digestive tract, which involves the esophagus, stomach and the duodenum (the upper portion of the small intestines). As we already mentioned, an endoscopy is recommended if there are certain digestive symptoms like bleeding or abdominal pain. An endoscopy can also be used to detect inflammation, polyp, ulcers and tumors.

Why an upper endoscopy over an x-ray? Because it’s a lot more accurate at being able to pinpoint any abnormal or even cancerous growths. Plus, if we do happen to find a suspicious growth or polyp we can easily take a sample of it to analyze. You wouldn’t be able to do that during an x-ray. Plus, we can also treat bleeding caused by ulcers and remove stuck objects found within the stomach or esophagus.

What You Should Know Before Your Endoscopy

Before your procedure you will want to sit down with us and tell us everything about your medical history including past surgeries, any heart conditions you may have, allergies to medications or if you are pregnant. It’s important that you give us as many details about your health and medical history as possible so that there are no complications. After all, your health is our top priority.

We will give you information on what you should and shouldn’t do prior to your procedure. For one, you won’t want to eat or drink anything for about eight hours before your endoscopy.

Tags: Crohn's Disease  

Crohn's disease is an inflammatory bowel disease that causes pain, severe diarrhea, and other serious symptoms. Glenn D. Madokoro, M.D., your Newport Beach, CA gastroenterologist, shares some signs that may indicate that you have Crohn's disease.Chrohn's Disease

Signs of Crohn's disease

Signs of Crohn's disease can vary in severity, but often include:

  • Pain and Cramps: Since Crohn's disease causes ulcers and inflammation of the lining of your digestive tract, it's not surprising that abdominal pain and cramps are common signs of the disease. It's much harder for food to move through the digestive tract when the lining is inflamed or contains ulcers. Mild to severe pain can occur during the digestion process due to these factors.
  • Diarrhea: Diarrhea often occurs with abdominal pain and cramps.
  • Bloody Stools: If you glance at the toilet bowl after a bowel movement, you may notice that your stools are bloody. Both red and dark blood may be a sign that you have Crohn's disease.
  • Appetite Issues: You may not feel like eating if you have Crohn's disease, which can lead to weight loss. Weight loss may also occur because inflammation may make it harder for your body to absorb nutrients from food.
  • Mouth Ulcers: Frequent mouth sores can be a sign of the disease.
  • Fever: Inflammations and infections in the digestive tract may trigger fevers.
  • Fatigue: You may feel more tired than usual and feel that you don't just have enough energy if you have Crohn's disease.
  • Perianal Problems: Inflammation can cause fistulas to occur around your anus. Fistulas are tunnels that develop under your skin.

How can a gastroenterologist help me?

Your Newport Beach ,CA gastroenterologist can prescribe medications that help reduce inflammation and suppress the substances produced by your immune system that cause the inflammation. Your doctor may also recommend other medications and therapies to relieve your symptoms, including pain medication, vitamin B12 shots, nutritional supplements and nutrition therapy. In severe cases, surgery may be needed to remove damaged areas of your digestive tract.

Contact Your Newport Beach, CA Gastroenterologist

Tags: Colonoscopy  

A colonoscopy might not be on the top of your priority list. However, this procedure is an incredibly important tool for preventing and colonoscopydiagnosing colon cancer, which affects about 150,000 new patients per year. But how can you tell if you should schedule a colonoscopy? Learn more with help from your Newport Beach, CA gastroenterologist Dr. Glenn D. Madokoro, MD at Newport Beach GI.

What can a colonoscopy do for me? 
Doctors use a colonoscopy to detect signs of gastrointestinal conditions and colorectal cancer. The medical procedure allows your doctor to visually see the lining of your rectum and colon to spot irregularities and precancerous or cancerous growths called polyps. Finding polyps early greatly decreases your chances of developing colorectal cancer. Colonoscopy also allows your doctor to investigate problematic symptoms of gastrointestinal issues like inflammatory bowel disease (IBD) and administer their treatments.

Colonoscopy in Newport Beach, CA
Colonoscopy uses a piece of medical equipment called a colonoscope. This long, thin tube, which is inserted rectally, has a tiny camera attached to the end. If necessary, your doctor uses miniaturized tools threaded through the tube to take biopsies or remove polyps. The procedure itself begins with a colon cleanse beginning a few days before the colonoscopy. This empties the colon for the test. On the day of your test, your doctor administers sedation medication to relax you during the procedure. After inserting the colonoscope into the anus, the tube moves through the rectum to the colon, then fills the colon with air. This allows your doctor to see the colon’s lining. After the procedure, you will be required to stay in recovery for about an hour. The medications you take before the procedure require that you bring someone to drive you home afterward.

When should I schedule a colonoscopy? 
The general rule of thumb is that patients over 50 with an average cancer risk should undergo a preventative colonoscopy every ten years. This gives Dr. Madokoro the chance to find any precancerous or cancerous polyps early, decreasing the chance of colorectal cancer or even preventing it altogether. Signs that you should schedule a colonoscopy include:

  • gastrointestinal irritation
  • constipation
  • irregular stools
  • chronic diarrhea
  • blood in the stool
  • sudden or unexplained weight loss

Your doctor can help you determine if a colonoscopy is best for you and your situation. For more information on colonoscopy, please contact Dr. Glenn D. Madokoro, MD at Newport Beach GI in Newport Beach, CA. Call (949) 548-8800 to schedule your appointment for an examination today!

Tags: Endoscopy  

If you live in the Newport Beach, CA area, and you have been told you need an endoscopy, chances are you have questions and Endoscopyconcerns. A qualified gastroenterologist, like Dr. Glenn D Madokoro, can help you answer those questions.

The following are some common questions and answers regarding endoscopy

What is an endoscopy?

An endoscopy is a minimally invasive medical procedure in which a long, flexible tube with a tiny camera is used to examine difficult to reach areas of the body. In an upper endoscopy, the tube is inserted down the patient’s throat to examine the esophagus, stomach and beginning of the small intestine.

What is the purpose of an endoscopy?

The purpose of an endoscopy is to examine, diagnose, and sometimes treat conditions of difficult to examine areas such as the upper and lower GI tract.

Why do I need an endoscopy?

Chances are your Newport Beach doctor wants to further examine your upper GI tract to either ensure nothing is wrong or to diagnose a condition and treat it.

Is the procedure safe?

Yes. Very few complications are associated with the procedure. Usually, it is done on an outpatient basis. However, if you experience any such symptoms as fever, chest pain, shortness of breath, bloody or dark stool, difficulty swallowing, persistent abdominal painor vomiting, call your doctor immediately and/or go to the emergency room.

How long will it take?

Typically, an endoscopy will take 15-30 minutes. Your doctor may ask that you stop taking certain medications prior to your procedure. You will also need to fast for a period of time, generally 4-8 hours, before the procedure.

What happens next?

As most endoscopies are done on an inpatient basis, you will probably be in and out of the doctor’s office within a couple of hours. However, since you will likely receive local anesthesia and/or mild sedative it’s a good idea to have someone else drive you to and from the doctor’s office, clinic or hospital. You could experience mild discomfort after the procedure, possibly a sore throat or minor abdominal discomfort. Depending on the purpose of the procedure, you should get the results of the procedure within a few hours to a few days.

People living in the Newport Beach, CA area who are seeking information about endoscopy or who need a qualified physician to administer an endoscopy might consider contacting Glenn D. Madokoro, M.D. For more information call (949)548-8800 or visit the website at

Tags: Colonoscopy  

A colonoscopy is a test used to examine your large intestine for signs of cancer and find the cause of other problems, such as abdominal pain. Initial colonoscopies are recommended at age 50, although they are used at any age to diagnose a gastrointestinal problem. ColonoscopyGastroenterologist Glenn D. Madokoro, M.D., of Newport Beach, CA, is here to share information about the colonoscopy process.

Why is colonoscopy prep so important?

Your Newport Beach gastroenterologist inserts a thin, flexible, lighted tube with a camera into your anus during your colonoscopy. As he gently guides the colonoscope through your colon, the camera transmits images to a monitor. If any fecal matter remains in your colon, your doctor won't be able to see the lining clearly. During colonoscopy prep, you'll clean out your colon with laxatives. Although you might find the process a little unpleasant, it's an absolutely crucial step.

What happens during a colonoscopy?

Before the procedure starts, you will be given a sedative or undergo general anesthesia to ensure that your body is completely relaxed during the procedure. You'll lie on your side while your gastroenterologist places the tube in your anus and guides it through your rectum and colon. The scope not only takes video images of your colon; it also pumps air into your colon to give Dr. Madokoro a clear view of the lining. Once the scope reaches the opening to your small intestine, your doctor will slowly withdraw it and take a second look at the lining of your colon.

What if a polyp is found during the colonoscopy?

Polyps are small growths on the lining of the colon walls that can eventually become cancerous. In addition to sending images of your colon to a monitor, the colonoscope can also be used to remove polyps. Any polyps removed during the procedure are sent to a laboratory for testing. You may notice some light bleeding after the colonoscopy if you have a polyp removed.

What is the colonoscopy recovery process like?

Plan to spend at least an hour or two at the outpatient center or hospital following a colonoscopy. During this time, the effects of the sedative or anesthesia will wear off and the medical staff will monitor you to make sure you aren't experiencing any issues. Someone will need to drive you home if you've had anesthesia. You may pass gas for a few hours after the procedure, but by the next day, you should feel completely normal.

Polyps are a small cluster of cells that grow on the lining of the colon. Most polyps tend to be harmless, and generally don’t cause noticeable symptoms. However, some polyps can eventually grow and develop into colon cancer. Colon cancer is the third most cancercommon form of cancer in men and women in the United States. When diagnosed and treated early, colon cancer can be treatable. Dr. Glenn D. Madokoro, a gastroenterologist in Newport Beach, CA, recommends that people become familiar with their individual risk factors and predisposition to developing polyps, and to undergo colonoscopy screenings to detect abnormal cell growth in the large intestine and rectum.

What causes polyps?

Abnormalities or genetic mutations can sometimes cause cells to proliferate and continue dividing beyond what is necessary for healthy cell function. In the large intestine (colon), this unregulated cell growth can lead to the formation of polyps in the lining of the colon.

Are polyps cancerous?

Generally, most polyps are benign and do not necessarily develop into cancer. Larger masses can increase the likelihood that they will become malignant, and other risk factors such as genetics and lifestyle factors can also play a role in the development of cancer.

What are the signs and symptoms of polyps?

Polyps generally do not present symptoms. In some cases, people with polyps may experience rectal bleeding, changes in bowel habits and stool color, nausea, abdominal pain, vomiting, iron deficiency and anemia.

What are the different types of polyps?

There are several types of polyps. The most common forms are:

  • Adenomatous - most common type, a small percentage usually become cancerous, however, they make up the majority of cancerous polyps.
  • Serrated - vary in shape and size and location in the colon. Serrated polyps located in the upper colon are harder to detect and more likely to become cancerous.
  • Inflammatory - usually develop as a result of ulcerative colitis or Chron’s disease, both of which can potentially increase a person’s risk of developing colon cancer.

Who is at risk for developing polyps?

Polyps are not uncommon and can develop in many people without becoming malignant. Dr. Madokoro advises his Newport Beach patients above the age of 50 to schedule a colonoscopy to screen for polyps (people with genetic predispositions to polyps and colon cancer may need to start screening earlier).

Other risk factors include:

  • Race (African Americans are at higher risk)
  • Alcohol and tobacco use
  • Obesity
  • Type 2 Diabetes

Has your Newport Beach, CA doctor, Glenn D. Madokoro, MD, talked to you about having a colonoscopy yet? A common medical procedure, colonoscopies are used to screen for signs of colon cancer and other dangerous conditions of the colon. Here are fourColonoscopy reasons you might need one.

1. You are Fifty or Older

Routine colonoscopies typically begin around fifty years of age for most people. Even if you have no warning signs or family history of colon cancer, your Newport Beach, CA doctor will likely recommend a colonoscopy around this age just to be safe.

2. You are at an Increased Risk for Colon Cancer

If you are one of the many Newport Beach, CA residents at an increased risk for colon cancer, however, your doctor will likely recommend that you have a colonoscopy sooner or more frequently. This will help ensure that, if something does develop, your doctor will know right away.

3. A Previous Screening Indicated Cause for Concern

While the majority of colonoscopy results come back normal, if yours indicates that there is some cause for concern, your doctor will want to see you back again more frequently. This will help your doctor make the best treatment decision for you.

4. You are Experiencing Several Symptoms Related to Your Bowels.

Colon cancer can present several symptoms. If you notice one or more of the following symptoms, call Dr. Madokoro in Newport Beach, CA to schedule a colonoscopy sooner rather than later.

  • Constipation
  • Diarrhea
  • Bloody stool
  • Stomach cramps
  • Unexplained weight loss

While these symptoms can just be the result of consuming the wrong foods, they can also be a sign that something is wrong. If any of the four descriptions above fits you, call Dr. Madokoro in Newport Beach, CA to set up an appointment for your next colonoscopy today.

Tags: Diverticulitis  

Diverticulitis Diverticulitis is an unfortunately common and painful disease of the digestive system. It occurs when pouches formed in the intestines and colon become inflamed. Symptoms include abdominal pain, diarrhea, fever, and nausea. The disease is diagnosed when symptoms are present and then confirmed with a blood test by your gastroenterologist. An ultrasound or CT scan may also be used to diagnose diverticulitis.

Diverticulitis can be so serious that it can down elite athletes. In 2009, professional wrestler and mixed martial arts star Brock Lesnar nearly lost his career when he was sidelined with diverticulitis. The athlete described this condition as feeling like a “shotgun blast to the stomach,” which says a lot coming from the former Ultimate Fighting Heavyweight Champion.

The Risks of Diverticulitis

  • Cancer
  • Bowel obstruction
  • Fistula
  • Bleeding
  • Peritonitis
  • Strictures

Blood loss may result in hospitalization for observation and intravenous fluids, particularly if it causes dizziness or loss of consciousness.

What Causes Diverticulitis?

Researchers and clinicians have been unable to pinpoint the cause of diverticulitis. Some doctors recommend a diet that includes probiotics and some recommend a high fiber diet. However, experts say there is not enough evidence on either to form a clinical recommendation.

Treatment for Diverticulitis

Depending on the severity of the disease, your doctor may recommend changes in diet or antibiotics if an infection is present. The American College of Gastroenterology guidelines also recommend colonoscopy after diverticulitis to rule out other conditions such as cancer. Patients should have a colonoscopy at least six weeks following the episode of diverticulitis and no more than 12 months after the condition has cleared.

In rare cases, surgery may become necessary to remove the bleeding diverticula. However, most patients stop bleeding on their own after a few days of observation.

If you experience abdominal pain and are concerned about diverticulitis, talk to your Newport Beach gastroenterologist. Dr. Glenn Madokoro of Newport Beach, CA treats patients with diverticulitis and can perform a colonoscopy to check for other conditions associated with the disease. Schedule an appointment today with your Newport Beach gastroenterologist if you are concerned that you may be at risk for diverticulitis.

Tags: Polyps  

Hearing your doctor say that you have polyps can be very frightening. What are polyps? Are polyps dangerous? Thankfully, the diagnosis is generally nowhere near as bad as it sounds. Read on to learn more about polyps and how endoscopy from Glenn D. Madokoro, MD in Newport Beach can help you achieve your maximum health.

What are Polyps?

Polyps are small tissue growths that can be found on any organ. The most common locations for polyps include the colon and the uterus, though they can be found in the nose, ear and stomach as well. Polyps can range in size from smaller than a quarter to several inches across, and you can have none, one or several.

Generally, polyps are not dangerous by themselves. Some types of polyps can be or become cancerous, however, so if your doctor finds one in your body, he or she will likely refer you to a specialized endoscopy professional, such as Dr. Madokoro in Newport Beach.

What Causes Polyps?

While polyps are relatively common, doctors are still uncertain as to what causes them. Doctors do know that age is the biggest risk factor and genetics may play a role as well. While few young adults have polyps, as many as one quarter of all senior citizens may have them at some point.

How are Polyps Identified?

Because most polyps cause no symptoms, doctors recommend that people come in for regular screenings, especially as they age. It is at these routine screenings that doctors will inspect the most at-risk parts of the body for any signs or symptoms of an abnormality.

How are Polyps Treated?

While most polyps are not dangerous, your doctor will want to check to make sure. If Dr. Madokoro finds a polyp, he will remove the polyp and have it biopsied to determine if it is cancerous, pre-cancerous or benign. Polyps are typically removed either with wire loop biopsy forceps or by burning them at the base with an electric current. Both procedures are routine and low-risk.

If your polyp is found to be benign, Dr. Madokoro will likely recommend future monitoring just to make sure that you stay well. The interval of time between screenings will vary from a few months to a few years, depending on the severity and number of the polyps that were found. If your polyp is found to be cancerous, Dr. Madokoro will discuss your treatment options with you from there.

Most polyps are not a cause for concern, but it's always better to be safe than sorry. Be sure to visit your doctor for regular screenings and don't be afraid to visit Dr. Madokoro in Newport Beach for endoscopy treatment if needed.

GIQuICYour Newport Beach gastroenterologist participates in an endoscopic quality improvement registry to promote more effective medical procedures.

According to the CDC, colorectal cancer is the third most common cancer in both men and women, and the second leading cause of cancer-related deaths in the US. The sooner cancer can be detected the better a patient’s prognosis. Therefore, we recommend that anyone at an increased risk for colorectal cancer see their Newport Beach gastroenterologist to get an endoscopy.

Endoscopies, such as a colonoscopy, allow us to assess the digestive system and detect abnormal growths and tumors like adenomas, and it’s vitally important at our practice to ensure that we are offering the best quality health care we possibly can to our patients to provide fast and accurate diagnosis for the most effective treatment plans. That’s why our very own Newport Beach gastroenterologist, Dr. Glenn D. Madokoro, is participating in the GIQuIC registry.

About GIQuIC

As of 2012, about 100,000 colonoscopies have been submitted to the GI Quality Improvement Consortium (GIQuIC). So what does this mean? Through these endoscopy case submissions the GiQuIC is able to provide information to improve the quality of your next procedure. The GiQuIC measures several important factors including adenoma detection rate, prep assessment and cecal intubation rate, to name a few. This information gives gastroenterologists like Dr. Glenn Madokoro peace of mind knowing that they are providing the best treatment measures possible. This also ensures that we are detecting precancerous growths like adenomas before they become full-blown cancer, which means easier and more effective treatments for our patients.

If it’s time for you to schedule your endoscopy in Newport Beach, be sure to call Dr. Glenn Madokoro to book your upcoming procedure. Those over the age of 50 should have a colonoscopy every 10 years to check for adenomas and other cancerous growths. If you are at an increased risk of developing colorectal cancer, tell your Newport Beach gastroenterologist and we’ll let you know how often you should be coming in.

Digestive IssuesAnyone with persistent digestive issues should consult a gastroenterologist, a doctor specializing in the digestive system, to address discomfort and diagnose any infections or diseases that may be causing health problems. Not all digestive conditions require an endoscopy to diagnose, but the procedure may be crucial to identifying and treating whatever problems you’re encountering with your stomach and other parts of your digestive tract.

What is an Endoscopy?

A gastroenterologist may use a device called an endoscope to examine your digestive tract. The endoscope is a flexible tube equipped with a light and camera, allowing the doctor to view your digestive tract on a monitor. An endoscopy is a non-surgical procedure helpful in identifying and treating stomach pain, ulcers, gastritis, constipation, diarrhea, growths in the colon and digestive bleeding. The gastroenterologist may use the scope to take a sample of tissue, known as a biopsy, to further diagnose any disease.

As an endoscopy isn’t a surgery, it doesn’t require significant recovery time. However, you’ll want to schedule the procedure for a time when you can adequately prepare for it. At minimum, you’ll need to fast for about 6 to 8 hours before the endoscopy, but if the doctor plans to examine your colon, you will need to take laxatives the day before the appointment in order to eliminate stool from your colon. Endoscopy patients are sedated during the examination, so you shouldn’t drive until the day after the procedure.

Call Glenn D Madokoro, MD if you are suffering from digestive issues

If you’re experiencing disruptive digestive issues, call your Newport Beach, CA, doctor about scheduling an endoscopy as soon as possible. Glenn D Madokoro, MD, not only performs endoscopy procedures, but offers a full array ofgastroenterology services to help you maintain a healthy digestive system. To learn more about Dr. Madokoro’s offerings or schedule an appointment, call (949) 548-8800 today. Your body will thank you!

Tags: Colonoscopy  
While a colonoscopy probably isn’t at the top of your list of things to do, it is one of the most important routine medical procedures you can have performed. According to the American Society for Gastrointestinal Endoscopy (ASGE), colorectal cancer is the third-most common cause of cancer deaths in the U.S.—and with a regular colonoscopy, it is almost completely preventable.
Using a thin flexible tubular instrument called a colonoscope, the procedure allows your gastroenterologist to look at the inside of the entire colon and rectum to detect precancerous growths or polyps. Polyps are abnormal growths in the colon lining. They are usually noncancerous and range in size. If polyps are detected during a colonoscopy, Dr. Madokoro will remove them for analysis. Cancer begins in polyps and removing them is a critical step to preventing colorectal cancer.
Most colonoscopies are administered on an outpatient basis, and the entire procedure usually only takes between 30 minutes and one hour. Following the colonoscopy, Dr. Madokoro can explain the results of the colonoscopy as soon as it has been completed.

Why might I need a Colonoscopy?

Most medical experts recommend a colonoscopy procedure starting at the age of 50 and usually once every 10 years thereafter. Some people may have a greater risk of developing colon abnormalities and require a screening earlier or more frequently, including people with a family history of colon cancer or someone with colon polyps or inflammatory bowel disease.

In addition to identifying abnormal polyps or precancerous growths, a colonoscopy can also help:
Determine the cause of abdominal pain, rectal bleeding or change in bowel habits
Diagnose or rule out many digestive disorders, including ulcerative colitis and Crohn's disease
Remove polyps before they become cancerous
Remove abnormal tissue samples for further testing
Stop intestinal bleeding
Monitor response to treatments if you have inflammatory bowel disease


Benefits of Newport Beach Colonoscopy

Colon cancer is called a silent killer because symptoms don’t usually present themselves until the cancer is too advanced for treatment. Early detection is the key to successful removal and treatment of colon cancer. The good news is that a colonoscopy in Newport Beach—a quick, 30 minute screening—is the only procedure that both detects and removes precancerous polyps during the same procedure.
If you have questions about colonoscopy, colon cancer or other abnormalities affecting the large intestine, contact Dr. Madokoro today or schedule a consultation online.
colonoscopyModern science has made it easier to view the body’s internal structures to search for early signs of disease, bleeding and more before conditions can become more severe. This is the case for Dr. Glenn Madokoro, who uses specialized, lighted tubes with cameras on the end known as endoscopes to view inside the body.
Dr. Madokoro performs a number of gastroenterology services, including colonoscopy and upper endoscopy. While he performs other endoscopic procedures, the upper endoscopy and the colonoscopy are two similar procedures that are indicated for different reasons. Knowing why Dr. Madokoro would recommend one procedure over another can help you better understand the procedure and what Dr. Madokoro may be looking for.
A colonoscopy is a procedure that involves inserting a colonscope that is specifically designed to view the rectum and colon. The colonscope is inserted via the anus and advanced up to the large intestine, extending up as high as the end of the small intestine.
By contrast, an upper endoscopy is inserted in the reverse direction. This procedure uses an endoscope inserted through the mouth and is advanced through the esophagus to the stomach, the duodenum and the small intestine. This allows Dr. Madokoro to visualize these tissues to determine if abnormalities are present.
Dr. Madokoro can recommend an upper endoscopy versus a colonoscopy for various reasons. In some instances, both may be performed in the same procedural time. Some reasons he may perform an upper endoscopy include if you have been vomiting bright red blood, experiencing stomach pain, having difficulty swallowing or if he suspects you may have an ulcer somewhere in your stomach or small intestinal lining.
A colonoscopy is typically performed to test for abnormalities in the colon, such as polyps that could indicate colon cancer. Other reasons Dr. Madokoro may recommend a colonoscopy is if you are experiencing symptoms such as dark blood in your stool, to test for the possible presence of inflammatory bowel disease or to determine the cause of anemia.
Whatever the procedure need or reason for the procedure, Dr. Madokoro and his staff will make every effort to ensure you thoroughly understand the procedure or procedures.

Polyps are abnormal growths of tissue that can be found in any organ that has blood vessels, such as the colon. To help you understand colon polyps in Newport Beach, Dr. Glenn Madokoro offers some helpful information so you can remain “in the know” about important gastrological topics.

What are Colon Polyps?

A colon polyp is a growth on the surface of the colon.  A person can sometimes have more than one polyp, which can be raised or flat. Some colon polyps are benign, which means they are not cancerous, but some may already be cancerous or will become cancerous.  Typically, flat polyps are smaller and harder to see, while they are more likely to be cancerous than raised polyps. With the use of a colonoscopy in Newport Beach, polyps can usually be removed.

So Who Gets Polyps?

Anyone can get colon polyps, but certain people might be more likely to get them than others. You may have a greater change of getting polyps if:
  • You are 50 or older
  • You have had polyps before
  • Someone in your family has had polyps
  • Someone in your family has had colon cancer
  • You’ve had uterine or ovarian cancer before age 50
It is also more likely for you to get colon polyps if you:
  • Eat a lot of fatty foods
  • Smoke
  • Drink alcohol
  • Don’t exercise
  • Weigh too much
By visiting Dr. Glenn Madokoro in Newport Beach, your polyps can be examined and removed.  Dr. Madokoro will work with you to create an appropriate treatment plan for treating your polyps in Newport Beach.
