Endoscopic Flexible Sigmoidoscopy

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

A flexible sigmoidoscopy is not usually painful. Some people describe feeling like they need to go to the bathroom right after the scope is inserted. That feeling usually goes away after a few minutes. Some people describe pressure or cramping that is similar to gas pains or bloating during the exam.

During a flexible sigmoidoscopy, a healthcare provider uses a scope to view the inside of the lower (sigmoid) colon and rectum. The procedure helps diagnose bowel problems, such as ulcerative colitis, an inflammatory bowel disease (IBD). It can also detect colon polyps that can become colon cancer.
