Colonoscopy

Definition/Overview

A colonoscopy is performed to check for colon cancer and to treat colon polyps. It is also used to evaluate problems such as blood loss, abdominal or rectal pain, changes in bowel habits, active bleeding of the bowel, and abnormalities that have been detected on a CT scan.

Procedure

A colonoscopy is performed as an outpatient procedure. Prior to this procedure, you will be given instructions on how to prepare, which includes emptying your colon using a prescribed laxative. You will be given medication to make you relaxed and drowsy, and you may not remember much of the experience at all. The physician will perform a rectal exam, and then insert a colonoscope. You may feel some slight cramping or urge to move your bowels, but generally there will be little discomfort.

The physician will examine your colon for abnormalities, and the entire process takes about 30 minutes. You will then be moved to a recovery area until the effects of the medication wear off. You will be given guidelines as to when to eat and drink, and how soon you can resume your normal routine (usually within 24 hours).
