Colonoscopy is an important procedure for diagnosing and treating diseases of the colon. In Canada, up to 13% all colonoscopies do not examine the full colon and are therefore incomplete. Incomplete colonoscopies happen for a number of reasons but are often due to twists and turns in the colon that make the colonoscopy difficult to perform and uncomfortable for the patient.

This randomized study is being done to test a new colonoscopy system called the Scope Guide that shows an exact 3-dimensional picture of how the colonoscopy is positioned in the patient's abdomen.

We hypothesize that the use of the Scope Guide for colonoscopy will improve measures of colonoscopy quality including rate of complete examination, patient comfort, polyp detection rate, insertion time, amount of sedation required, and need for abdominal compression.
