Sigmoidoscopy

 

What is a sigmoidoscopy?

A sigmoidoscopy is an examination of the lower 20 inches of the colon (also known as the sigmoid colon) with a lighted, flexible tube about the thickness of your finger. The doctor will insert the tube through your rectum and into the lower portion of your colon. Often during the sigmoidoscopy, the doctor may perform other minor procedures such as a polyp (abnormal clump of skin tissue) removal. In addition, if necessary, a small piece of tissue (a biopsy) can be taken for examination in the lab. Please remember that biopsies are taken for many reasons and do not necessarily imply cancer.
