Upper Gastrointestinal Endoscopy

An upper gastrointestinal (UGI) endoscopy is a procedure that allows your doctor to look at the inside lining of your esophagus , your stomach, and the first part of your small intestine (duodenum ). 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.
