Understanding Upper Endoscopy

What is Upper Endoscopy (EGD)?

Upper endoscopy lets your doctor examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first portion of the small intestine). Your doctor will use a thin, flexible tube called an endoscope, which has its own camera lens and light source. This transmits the images to a video monitor. You might hear your doctor or other medical staff refer to upper endoscopy as upper GI endoscopy or esophagogastroduodenoscopy (EGD).
