Flexible Sigmoidoscopy

A Flexible Sigmoidoscopy allows your physician to examine the lining of your colon and rectum (the large intestine). The difference between a Colonoscopy and Sigmoidoscopy is the Flexible Sigmoidoscopy is able to evaluate the last third of your colon, while the colonoscopy looks at the entire colon. The Flexible Sigmoidoscopy is normally performed to evaluate for rectal bleeding and diarrhea.
