Second-Generation Endocuff Versus Distal Cap Versus Standard High-Definition White-Light: No Overall Difference but More Detected Adenomas and Shorter Withdrawal Times in Screening Exams With Endocuff

This study from 3 U.S. centers is the first to compare the second-generation Endocuff Vision (Olympus America, Center Valley, Penn, USA) to distal cap (Reveal; STERIS, Mentor, Ohio, USA) and high-definition white-light endoscopy (HDWLE).
There were 1142 randomized subjects (81.3% male) included in the analysis and approximately 20 endoscopists.
Adenoma detection rates (ADRs) were high in all 3 arms at 57.3% for HDWLE, 59.1% for Endocuff, and 55.7% for the distal cap. There were no differences between the groups for advanced ADR, sessile serrated lesion detection rate, or right-sided colon ADR. Among the 46% of subjects undergoing screening, there was a trend toward higher ADR with Endocuff at 56.8% versus HDWLE at 47.7% versus distal cap at 44.2% (P=.051). Adenomas per colonoscopy was higher with Endocuff in the screening population (1.7) compared with HDWLE (1.3) and distal cap (1.2) (P=.048). Further, withdrawal time trended toward a shorter duration with Endocuff, a difference that reached significance for the overall study at 8.4 minutes versus 9.8 minutes with HDWLE and 8.6 with distal cuff (P=.02).
