A Colonoscopy is a procedure that enables the doctor to see the inside of your entire large intestine or colon. It allows the physician to see the surfaces of the bowel using a fiberoptic tube. Colonoscopy can be done for various reasons. This procedure can be used to examine inflamed tissues, abnormal growths, ulcers biopsies. It is also used for screening while removing polyps, and to look for early signs of cancer in the colon and rectum.



Colonoscopy is done using a colonoscope. The colonoscope is a four-foot long, flexible tube that has a camera and a tiny torch attached at its tip. A colonoscope is inserted through the rectum slowly, under visual control and is slowly advanced to the other end of the large intestine.

The colonoscope being so flexible can be moved around the curves of the colon. The scope also blows air into the colon, helping the colon to expand that enables the doctor to see clearly.
