An enteroscopy is a test that looks at the small intestine. An endoscope, a thin, flexible tube with an attached light, is placed into the mouth and passed into the upper gastrointestinal tract. The endoscope allows views of the small intestine. This test is often done to check for intestinal diseases and tumors. The test is conducted in the case of unexplained gastrointestinal bleeding, diarrhea or unusual X-ray results.
