EGD (Esophagogastroduodenoscopy) is a procedure that examines the esophagus, stomach and first portion of the duodenum (small intestine) using a long flexible tube, with a camera at the end of it. The scope is inserted into the mouth and advanced to the small intestine. This procedure lasts usually about 10 minutes and recovery takes another 20 minutes or so. In upper endoscopies, we can visualize the esophagus, stomach, and duodenum. Biopsies or tissue samples are taken which can evaluate for bacteria, cancerous tissue and inflammation. Esophageal strictures, which are narrowing, can be seen and dilated if necessary.
