Endocuff Vision‐assisted colonoscopy: a randomized controlled trial. Issue 5 (21st March 2019) - Jacob, Abraham
Abstract : Background: Adenoma detection rate (ADR) has shown to be an independent predictor, to reduce the rate of interval colorectal cancer. Endocuff Vision is a relatively new device that has shown promise to improve the ADR. The primary objective was to conduct a randomized controlled trial to compare Endocuff Vision‐assisted colonoscopy (EVAC) with standard colonoscopy (SC). The primary outcome of the study is ADR and the secondary outcomes are caecal intubation rate, terminal ileum intubation rate, scope withdrawal time, quality of bowel preparation and adverse events. Methods: A randomized controlled trial was performed to compare EVAC versus SC. All patients who presented to the endoscopy suite at the Queen Elizabeth Hospital were assessed for eligibility. Patients were recruited from 15 June 2016 to 20 January 2017. A total of 360 patients were included; 40 were excluded. The patients were randomized using block randomization; 138 patients were recruited to SC and 182 to EVAC. Results: A total of 231 polyps were retrieved during the study period. Polyp detection rate (PDR) was high in both groups: 53% in the EVAC group versus 41.1% in SC. This was statistically significant with a P ‐value of 0.035. ADR was similarly high in both groups: 36.81% in EVAC group versus 28.99% in SC group. ADR did not reach statistical significance. Conclusions: EVAC does improve the PDR. Though the ADR did not reach statistical significance, there is a trend towards improved adenoma detection and there is statistical significance in the overall PDR. Abstract : This is a brief paper looking at the benefit of capped devices for improving the efficiency of colonoscopy. Polyp detection can reduce the incidence of interval colorectal cancer. This is a randomized controlled trial comparing the benefit of Endocuff Vision versus standard colonoscopy.
