Endoscopy is an examination using a tube-like device with a light on the end. A camera at the end of the tube transmits the lighted image before the tube to a TV screen so the the examiner can see the inside of the upper gastrointestinal tract as the tube advances.
A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon. If necessary, polyps or other types of abnormal tissue can be removed through the scope during a colonoscopy. Tissue samples (biopsies) can be taken during a colonoscopy as well.
