Flexible sigmoidoscopy

A sigmoidoscopy, also called a flexible sigmoidoscopy, is a procedure that lets your doctor look inside your sigmoid colon by using a flexible tube with a light on it. It helps your doctor check for:

• ulcers
• abnormal cells
• polyps
• cancer

You don’t need bowel preparation for that. You need to fast for 6 hours and will be given enema before the procedure.
