Mo1674 DIFFERENCES IN DETECTION OF POLYP PATHOLOGY BASED ON ENDOSCOPIST CHARACTERISTICS AND EXAMINATION OF THE ROLE OF WITHDRAWAL TIME IN EXPLAINING THESE DIFFERENCES

Previous studies have demonstrated adenoma detection (AD) to be operator dependent. In this study we examined endoscopist characteristics not only as they relate to AD, but also to sessile serrated adenoma detection (SSPD), and advanced adenoma detection (AAD--defined as ≥1cm diam., having villous component or high-grade dysplasia). Further, we examined the role of withdrawal time (amount of time spent viewing as colonoscope is withdrawn) as a possible explanation of these differences.
