This is a test in which a thin, black, flexible tube with a lighting system on the end is passed through the anus, into the rectum, in order to examine the large bowel or intestine, also called the colon. Colonoscopy is a very good test for examining the colon for polyps (warty growths that can turn into cancer), but it is not perfect. In fact, about 30% of polyps that are under 5 mm (about 1/5 of an inch) in size are missed during colonoscopy because they are hiding behind folds and bends in the colon. This research study is being done to determine if performing colonoscopy with a cap on the tip of the colonoscope will reduce the miss rate for polyps. A cap is a clear plastic hood that fits on the tip of the colonoscope and sticks out about 1/3 of an inch. During colonoscopy, the cap can be pressed against a fold or ridge in order to flatten it, so that the lining on the other side can be more easily seen. This may reduce the miss rate for colon polyps.

Primary | Number of Adenomas | Cap Fitted Colonoscopy (CFC) may significantly reduced miss rates for colorectal adenomas, specifically for small adenomas. This study is the first North American study of any design and the largest tandem study of CFC. CFC is a safe, simple, and inexpensive technology that could improve the reliability of colonoscopy in detecting colorectal neoplasia. Additional study of CFC in Western populations is warranted. | after the second colonoscopy is completed | |
Secondary | Time for Examination Will be Measured With a Stopwatch, and the Stopwatch Will be Stopped at Any Time a Polyp is Located and Restarted When the Polyp Has Been Removed and Retrieved. | During the second colonoscopy, all polyps will also be removed when detected. Any polyp identified and removed during the second procedure will be counted as a miss for the first procedure. All polyps will be sent separately for pathologic evaluation. The time required to remove and retrieve polyps with and without the cap on will be measured using a stopwatch as a secondary end point. The primary end point will be the miss rate for colonoscopy with the cap and colonoscopy without the cap. | after 2nd colonoscopy was completed in 24hrs |
