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).

What kind of doctor does endoscopy?

Most often, a gastroenterologist will do an upper endoscopy in a doctor's office, GI clinic, or hospital. A gastroenterologist is a doctor who specializes in the GI tract. Many other specialists can perform an upper endoscopy as well.

Is gastroenterology the same as endoscopy?

A colonoscopy and upper endoscopy are two procedures performed frequently by gastroenterologists to view and examine various portions of your digestive tract. Colonoscopies inspect the large intestine (colon and rectum) while upper endoscopies observe the esophagus, stomach and the first part of the small intestine.
