Why is sigmoidoscopy done?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Sigmoidoscopy is only able to visualize the lowest portion of the colon and the rectum. People undergoing this procedure are asked to stay on a liquid diet for a day or so and on test day receive a couple of flushing enemas so the doctor can see the lining of the colon unobstructed. This procedure doesn't require sedation and can be performed in the doctor's office. If a polyp is found, it can be removed during the procedure and sent to a pathologist for review.
