A rigid sigmoidoscopy is a procedure to look inside your rectum and sigmoid colon. The sigmoid colon is the lower part of your intestines, closest to your rectum. A sigmoidoscope will be inserted into your rectum. This is a firm tube with a light and tiny camera on the end. Pictures of your colon appear on a monitor during the procedure. A rigid sigmoidoscopy may help diagnose colon diseases, inflammation, polyps (growths), or infections.
