Sigmoidoscopy Procedure

What is it?

The sigmoid colon is the last part of the large intestine prior to the rectum. Sigmoidoscopy allows physicians to examine the large intestine and rectum to check for abnormalities and take tissue samples, if necessary.

How is it Done?

You will be placed on your left side, at which time your doctor will insert a sigmoidoscope into your rectum and slide it forward to examine your colon. A sigmoidoscope is a lighted, flexible tube with a camera on the end of it. The procedure takes about 15 minutes. There may be some bloating or mild cramping afterwards.

Why is it done?

Sigmoidoscopy is used to check for colorectal cancer. This procedure is recommended for people age 50 and over.
