What is a colonoscopy like?

A simple test. After appropriate colon preparation at home, arrive at the endoscopy center, change into a gown & IV is inserted. Once in the procedure room, final consent is obtained, IV sedation is given (there are options here--some patients choose no sedation, others want to be "out cold"), & a thin flexible tube with video camera is inserted per rectum & advanced, taking pictures, biopsies, & therapeutics.
