Esophagogastroduodenoscopy anatomy

EGD/ Upper Endoscopy


Esophagogastroduodenoscopy (EGD/Upper Endoscopy) is a procedure to examine the esophagus, stomach, and first part of the small intestine (duodenum).

EGD is typically performed to investigate symptoms such as heartburn, difficulty swallowing, abdominal pain, nausea, or vomiting. In patients with gastrointestinal bleeding, EGD can be used to identify and treat the source of bleeding.


After proper sedation to ensure patient comfort, a flexible instrument is inserted into the mouth and carefully advanced into the esophagus, stomach, and duodenum. The linings of these organs are carefully inspected by the provider using images transmitted by the scope to a television monitor. Any abnormalities can be biopsied for further analysis.

This procedure typically takes 15 minutes to perform.
