Use of wide-screen, high-definition monitors for improving adenoma detection: A prospective, randomized, controlled trial

Background and Aim Colonoscopy is sensitive at detecting large polyps; however, a significant polyp miss rate is still recognized. Indicators such as the adenoma detection rate (ADR) and, more recently, the adenoma per colonoscopy rate (APC) are increasingly used to ensure quality in colonoscopy. We carried out a prospective, randomized, controlled study evaluating improvement in adenoma detection between wide‐screen, high‐definition (WSHD) monitors compared to standard monitors (SD). Methods Patients undergoing screening or surveillance colonoscopy were randomized to a WSHD room or SD. Polyp size, location, shape, and histology were recorded. Right‐sided polyps were considered to be those proximal to the splenic flexure. Results A total of 152 patients were enrolled in the study, with 78 (51.3%) and 74 (48.7%) enrolled in the WSHD and SD groups, respectively. A 10% absolute difference in favor of the WSHD group was noted for the ADR (41% vs 31% patients); however, the difference was statistically not significant. In the WSHD and SD groups, APC of 0.9 ± 1.4 versus 0.7 ± 1.4 (P = 0.49) were noted, respectively. For polyps
