An esophagogastroduodenoscopy (EGD) is an outpatient procedure that is used to examine your esophagus, stomach, and the first part of your small intestine (called the duodenum). An EGD is sometimes called an upper endoscopy because it is used to evaluate the condition of your upper gastrointestinal tract.
The tip of the endoscope is inserted through your mouth and then gently moved down your throat into the esophagus, stomach, and duodenum (upper gastrointestinal tract). Since the entire upper gastrointestinal (GI) tract can be examined during this test, the procedure is sometimes called esophagogastroduodenoscopy (EGD).
