Flexible Sigmoidoscopy

What is Flexible Sigmoidoscopy?

A Flexible Sigmoidoscopy is an exam used to evaluate the lower part of the large intestine (colon). During a flexible sigmoidoscopy exam, a thin, flexible tube with a tiny video camera is inserted into the anus.

A tiny video camera at the tip of the tube allows the doctor to view the inside of the colon and take pictures if needed for future reference. The tube is inserted into the sigmoid colon and most of the descending colon — just under 2 ft (about 50 centimeters) of the large intestine. If necessary, biopsies can be taken through the scope during a flexible sigmoidoscopy exam.

What is the purpose of Flex Sigmoidoscopy?

Flex Sigmoidoscopy is commonly performed to explore possible causes of abdominal pain, rectal bleeding, changes in bowel habits, chronic diarrhea and other intestinal problems.

Sigmoidoscopy may occasionally be preferred over colonoscopy in cancer colon screening because the preparation for sigmoidoscopy and the test itself may take less time. In addition, an anesthetist is often not required.

How long does it take?

A Flexible Sigmoidoscopy exam typically takes about 15 minutes. It may require slightly more time if biopsies are taken. Sedation and pain medications usually aren’t necessary. If a polyp is found, your doctor will likely recommend a full colonoscopy to look at your whole colon, as other polyps may be present further up in the colon.
