Frequently Asked Questions

How do you prepare for a flexible sigmoidoscopy?

To prepare for a flexible sigmoidoscopy, the gastrointestinal tract must be emptied by following a clear liquid diet for 1 to 3 days before the procedure—similar to the preparation for colonoscopy. A laxative or an enema may also be required the night before a flexible sigmoidoscopy.

What does a flexible sigmoidoscopy involve?

A flexible sigmoidoscopy (sig-moi-DOS-kuh-pee) is an exam used to evaluate the lower part of the large intestine (colon). During a flexible sigmoidoscopy exam, a thin, flexible tube (sigmoidoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the rectum, the sigmoid colon and most of the descending colon - just under the last 2 feet (about 50 centimeters) of the large intestine.
