How much of the colon is examined during a colonoscopy?
A doctor has provided 1 answer
All of it!: The intention with colonoscopy is to examine the entire length of the colon. Sometimes due to tortuosity (or twisty-ness), it is difficult or impossible to see the entire colon. Other ways to evaluate the colon include virtual colonoscopy and barium enema. The advantage of colonoscopy is if anything is found, it can be biopsied or removed often times right away.
