No Benefit of Endocuff Vision in Screening Flexible Sigmoidoscopy
Douglas K. Rex, MD, FASGE, reviewing Rees CJ, et al. Gut 2020 Apr 3.
Endocuff Vision (EV) has well-established benefits in colonoscopy, both for improved detection and faster withdrawal without reduced detection.
EV has not been tested for its benefits in flexible sigmoidoscopy. In a randomized controlled trial in the UK, 3222 participants were randomized to screening flexible sigmoidoscopy with EV or without. The adenoma detection rate (ADR) was numerically, but not significantly, higher with EV than without (13.3% vs 12.2%; P=.35). Withdrawal time with EV (mean=3.32 minutes) was not different than without EV (mean=3.44 minutes). The average reach of the sigmoidoscope without EV was further than with EV (P<.001), and discomfort scores were greater with EV attached to the sigmoidoscope.
