Flexible sigmoidoscopy enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon . Because it does not extend up through colon, flexible sigmoidoscopy is not sufficient to detect polyps or cancer in this area. Physicians use it to look for the presence of several conditions including early signs of cancer in the descending colon and rectum. Color images are sometimes taken using video capture technology. Therapy can be administered directly through the sigmoidoscope.

For the procedure, you will lie on the examining table, while the physician inserts a short, flexible, lighted tube into your rectum and slowly guides it into your lower colon. The scope transmits an image of the inside of the rectum and colon, so the physician can carefully examine the lining of these organs. The scope also blows air into these organs, which inflates them and helps the physician see better. Flexible sigmoidoscopy is a relatively simple and painless procedure and usually lasts less than fifteen minutes.

Any questions regarding this or any other Endoscopic procedure should be directed to your physician.
