What is the purpose of a gastroscopy?

A gastroscopy allows Dr. Bookman to observe the upper portion of the intestinal tract, including the esophagus, stomach and duodenum. Dr. Bookman will be able to diagnose problems in these areas such as ulcers, tumors, or causes of bleeding. During the gastroscopy Dr. Bookman will also be able to take a biopsy, remove foreign objects or polyps, or dilate areas which have become narrowed.

How is a gastroscopy done?

A long, flexible tube is passed through your mouth and down into the esophagus. Your throat will be frozen to make passing the tube easier and you may be given some sedation. This tube carries with it a light source so that the doctor can see the area the tube is passing through. The tube will not interfere with your breathing. Sometimes air is inserted through the tube, this may cause you to feel some bloating and to burp.

What can I expect after the gastroscopy?

You must pre-arrange for someone to be available to drive you home at any time following your procedure. You will not be able to drive yourself if you have had sedation.

You will not be allowed to eat or drink for one hour after the test. It is then advisable to start slowly with cool drinks for the next hour or two. You may have a sore throat and feel bloated. Burping will help to relieve the bloating. Do not drink alcohol for the rest of the day.

If you have any severe pain in your chest or abdomen or if you have difficulty breathing or swallowing you must contact your doctor immediately.

Dr. Bookman will speak to you after the test, to give you the results, however, you will be sleepy and may not remember. You may want to make an appointment to see the doctor to discuss the results on a separate day.
