An upper endoscopy is a procedure used to visually examine your upper digestive system with a tiny camera on the end of a long, flexible tube. A specialist in diseases of the digestive system (gastroenterologist) uses an endoscopy to diagnose and, sometimes, treat conditions that affect the esophagus, stomach and beginning of the small intestine (duodenum).
The medical term for an upper endoscopy is esophago-gastroduodenoscopy. You may have an upper endoscopy done in your doctor's office, an outpatient surgery center or a hospital.
