What Is Endoscopy?
For those not immersed in the world of gastroenterology (GI), endoscopy refers to nonsurgical procedures that allow a physician to examine the digestive tract. In these procedures, a flexible tube with a small light and camera attached (an endoscope) is inserted into the mouth or the rectum. Physicians can then inspect, take pictures, and perform therapies like removing polyps and taking biopsies. The two most common endoscopic procedures are 1) upper endoscopy, which looks at the first part of the small intestine and 2) colonoscopy, which examines the lower intestine (colon).
