A sigmoidoscopy is a diagnostic procedure used to examine the end of the large intestine (colon) and rectum. It is an accurate way of detecting changes or abnormalities in the bowel, such as polyps which may develop into cancer. Tissue samples, called biopsies, can also be taken during a colonoscopy.

A sigmoidoscopy uses an endoscope, which is a long, thin, flexible tube with a tiny video camera at one end, to examine the inside of the colon and rectum. During the procedure, the endoscope is inserted into your rectum and gently fed through your colon. Images are transmitted from the camera at the tip of the tube to an external monitor. This enables the doctor to get a detailed view of the inside of your colon. Instruments can be inserted through the colonoscope to take tissue samples or remove polyps. In contrast to a colonoscopy, a sigmoidoscopy examines the end of the large bowel only, rather than the entire colon. The procedure is therefore shorter and lasts for approximately 10 minutes.
A sigmoidocopy is used to:
Investigate the possible causes of bleeding from your bottom or blood in your stools. Assess for causes of pain or discomfort in the back passage. Monitor the bowel if you’ve previously had a diagnosis of ulcerative colitis or Crohn’s disease. Follow up if you’ve had polyps removed from the end of the large bowel previously
You might be offered a sigmoidoscopy if you:
Have a variety of lower gastrointestinal symptoms needing further investigation. Have Inflammatory Bowel Disease (Crohn’s disease or ulcerative colitis).
