Flexible Sigmoidoscopy & Procedure Instructions
Flexible sigmoidoscopy is an endoscopic technique for visually inspecting the lower third of the colon and rectum with the use of a flexible tube with a light on the end. The examination is usually performed when visualization of the whole colon is not required. Examples include the evaluation of rectal bleeding, checking the status of an established patient with inflammatory bowel disease, or an abnormality seen on barium enema/CAT scan. Although flexible sigmoidoscopy was previously used as a tool for colon cancer screening, a full examination of the colon with a colonoscopy is now preferred and recommended.
