Colonoscopic techniques in polyp detection: An Egyptian study

EndoCuff-Assisted Colonoscopy Versus Standard Colonoscopy in Colonic Polyp Detection-Experience from a Single Tertiary Centre

Background. Standard colonoscopy fails to visualize the entire colon mucosa and consequently a significant amount of polyps are still being missed. New device, such as EndoCuff, have been developed to improve mucosal visualisation, hence the quality in colonoscopy. The aim of this study was to assess the diagnostic yield of EndoCuff-assisted colonoscopy in comparison with standard colonoscopy by taking into consideration several quality indicators. Methods. In this study, 965 adults ≥ 18 years referred for colonoscopy were randomly divided into two groups. The main statistical investigation compared the difference between EndoCuff-assisted colonoscopy (EC) vs. standard colonoscopy (SC) in the detection of colonic polyps and adenoma detection rate (ADR). The second inquiry sought to compare experienced vs. recently trained and female vs. male operators. Results. The ADR was higher for EC than for SC (37.50% vs. 26.64%). Regarding the mean number of detected polyps per procedure (MPP), the result was statistically significant when generally comparing the EC vs. SC (p=0.0009). There were no differences in MPP between EC and SC for recently trained endoscopists (p=0.7446), while a significant difference for experienced doctors (p=0,0020) was noted. A significant difference was observed between female doctors and male doctors only when using SC. EC was more helpful for female doctors when assessing MPP (p=0.0118). No serious adverse events related to EndoCuff-assisted colonoscopy was noted. Conclusions. EndoCuff-assisted colonoscopy seems to be safe and may bring benefits for improving the polyp/adenoma detection rates in regard to missed lesions, usually located in blind areas.
