A colonoscopy is an internal examination of the colon (large intestine) and rectum, using an instrument called a colonoscope.
The colonoscope has a small camera attached to a flexible tube. Unlike sigmoidoscopy, which can only reach the lower third of the colon, colonoscopy examines the entire length of the colon.
