Colonoscopy is the technique that allows the direct visualization of the large bowel. This procedure involves passing an endoscope with a diameter of ~1.3cm via the rectum into the large bowel. The endoscope is a flexible tube attached to an optical system that allows the diagnosis, treatment of any abnormalities. Additional therapeutic procedures can also be performed at the same time, such as endoscopic polypectomy, injection or banding of piles and tumor biopsy. Colonoscopy may not be completed if bowel preparation is sub-optimal or anatomical variation exists.
