Purpose:

Adenoma detection rate (ADR) is a validated marker for reducing the risk of interval colorectal cancer after a screening colonoscopy. Recent studies suggest that novel devices attached to the colonoscope tip may improve the ADR of doctors performing a screening procedure


Study summary:

Recent studies indicate that continuing medical education, time of colonoscopy during the day, forced longer withdrawal time, use of high definition colonoscopes all result in improving ADR although the gains have only been modest. To this end, adding novel devices to the tip of colonoscope may improve the ability of doctors to perform a better procedure. We therefore propose to identify the increase in ADR with 3 of these devices compared to standard colonoscopy. Fuse colonoscopy (2 cameras embedded at the side of the colonoscope tip providing an increased angle of view), EndoCuff (a plastic cap to fit the tip with flexible arms which hold the mucosa back aiding in inspection), EndoRings (similar to EndoCuff but the arms are wider) have been shown in tandem colonoscopy studies to improve the adenoma miss rates to 7-15% instead of the miss rates seen with standard colonoscopy which is usually about 40%. All these devices are FDA approved and are distributed in the United States.
