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.
