Sigmoidoscopy: Understanding the Procedure & Its Purpose

A sigmoidoscope is a thin, flexible tube with a light and a camera on the end. It is inserted into the rectum and colon to allow the doctor to examine the inside of these organs. Sigmoidoscopy is a procedure that uses a sigmoidoscope to look for abnormalities in the rectum and colon, such as polyps, tumors, and inflammation. Polyps are small, fleshy growths that form on the lining of the rectum and colon. Most polyps are not cancerous, but some can develop into cancer. Tumors are abnormal growths of tissue that can be cancerous or non-cancerous. Inflammation is a condition in which the tissue of the rectum and colon becomes red, swollen, and irritated.

Sigmoidoscopy is used to:

• Screen for colorectal cancer

• Diagnose digestive problems

• Remove polyps

• Treat bleeding or inflammation
