Procedure

Flexible Sigmoidoscopy

Flexible Sigmoidoscopy

A sigmoidoscopy is a visual examination of the lower large intestine and the rectum using a lighted, flexible tube. This procedure is similar to a colonoscopy; however, in a sigmoidoscopy, only the lining of the rectum and the lower portion of the colon is examined.  If polyps are found during a sigmoidoscopy, your physician will usually recommend a colonoscopy (a complete examination of the colon) to search for additional polyps that may be present in areas of the colon that were not visualized by the sigmoidoscopy.

Sedation techniques and preparation for the exam varies. Please follow your physician’s written instructions for dietary restrictions, bowel prep and medication modification.
