About Gastrointestinal Endoscopy
Gastrointestinal endoscopic procedures allow the gastroenterologist to visually inspect the upper gastrointestinal tract (esophagus, stomach and duodenum) and the lower bowel (colon and rectum) through an endoscope, a thin, flexible device with a lighted end and a powerful lens system. Endoscopy has been a major advance in the treatment of gastrointestinal diseases. For example, the use of endoscopes allows the detection of ulcers, cancers, polyps and sites of internal bleeding. Through endoscopy, tissue samples (biopsies) may be obtained, areas of blockage can be opened and active bleeding can be stopped. Polyps in the colon can be removed, which has been shown to prevent colon cancer.
