Optical Colonoscopy Fly Through

The following video, narrated by Dr. Patrick Pfau, offers an inside look at a what happens during an optical colonoscopy at UW Health in Madison, Wisconsin.


During a colonoscopy a flexible tube with a small lens and video camera is passed the length of the colon. The camera allows the doctor to see the entire colon. The colonoscope also allows tools such as forceps or snares to be passed into the colon to sample tissue or remove polyps, as demonstrated in the video.


Warning: The following video contains graphic images from actual optical colonoscopies with polyp removal.
