    Upper Gastrointestinal Endoscopy

    An upper gastrointestinal (UGI) endoscopy is a procedure that allows your doctor to look at the inside lining of your esophagus camera.gif, your stomach, and the first part of your small intestine (duodenum camera.gif). A thin, flexible viewing tool called an endoscope (scope) is used. The tip of the scope is inserted through your mouth and then gently moved down your throat into the esophagus, stomach, and duodenum (upper gastrointestinal tract).

    This procedure is sometimes called esophagogastroduodenoscopy (EGD).

    Using the scope, your doctor can look for ulcers, inflammation, tumors, infection, or bleeding. He or she can collect tissue samples (biopsy), remove polyps, and treat bleeding through the scope. Your doctor may find problems that do not show up on X-ray tests.

    This test can sometimes prevent the need for exploratory surgery.

    • Collect tissue samples (biopsy) to be looked at in the lab.
    • Remove growths (polyps) from inside the esophagus, stomach, or small intestine.
    • Treat upper GI bleeding that may be causing anemia.
    • Remove foreign objects that have been swallowed.

    How To Prepare

    • Have heart problems.
    • Are or might be pregnant.
    • Have diabetes and take insulin.
    • Have had surgery or radiation treatments to your esophagus, your stomach, or the upper part of your small intestine.
