Colonoscopy

During this procedure a colonoscope (a thin flexible tube with a camera and light on the end) is guided up the rectum and the colon under sedation. This is used to perform a thorough examination of the inside of the entire colon. We can remove colon polyps and/or take biopsies to diagnose any abnormalities. Of any form of colorectal cancer screening, colonoscopy has the best sensitivity for finding colon polyps and is able to prevent colon cancer by removing those precancerous polyps during the procedure. To get a good exam, the colon must be cleaned out with a colon prep prior to the procedure. In addition to colorectal cancer screening, we use colonoscopy to diagnose colonic disorders such as ulcerative colitis, Crohn's disease, and microscopic colitis and to look for causes of rectal bleeding.
