ID: 3520197 INTERIM ANALYSIS OF A MULTICENTER RANDOMIZED CONTROLLED TRIAL COMPARING THE RIGHT COLON ADENOMA AND SERRATED POLYP MISS RATES WITH COLONOSCOPY USING WATER EXCHANGE AND CARBON DIOXIDE INSUFFLATION

Missed lesions contribute to post-colonoscopy colorectal cancer (PCCRC). Single-center randomized controlled trials (RCTs) (JCG 2020 [in press]; GIE 2020;91:AB108) showed a significant reduction in right colon adenoma miss rate (rAMR) using water exchange (WE) compared to carbon dioxide (CO2) or air insufflation. Generalizability of these results awaits confirmation by a multicenter trial. We are conducting a prospective multicenter RCT to test...
