Description: A small flexible scope with a camera mounted on the end (sigmoidoscope) is inserted into the rectum and guided up the colon examining the lower portion of the colon. Specimens can be taken of the colonic lining at the time of the study. A doctor (or sometimes a nurse) performs the test with the assistance of a nurse in a doctor's office, endoscopy center, or hospital. The Gastroenterologist interprets the results. If specimens are obtained, a Pathologist interprets the results. The test takes 10-30 minutes to perform.
