Endocuff Vision Improves Detection in High Performers

In meta-analyses, Endocuff Vision (ECV) typically increases adenoma detection rates (ADRs) by about 7%. However, one meta-analysis found that the benefit was primarily in doctors with low ADRs.

In this French single-center study, 22 endoscopists with prior experience with ECV were divided into 2 groups. Half the endoscopists were randomized to use ECV for a period of time, then switch to standard colonoscopy without ECV, and the other group did the opposite sequence. Most of the patients had diagnostic or surveillance indications.

The mean cecal intubation time was 26 seconds shorter with ECV, and the mean withdrawal time was 36 seconds shorter. Despite that, ADRs in both groups increased by about 10%. With ECV, ADRs increased for all sections of the colon, except the rectum, where the ADR was only 1.2% higher. The most novel result was that, among doctors with baseline ADRs ≥ 25%, ECV increased ADR from 31.3% to 41.4%. ADR increased by 6.3% in doctors with baseline ADRs <25%, which did not reach significance, perhaps because there were only 6 such doctors.
