Latest Generation Colonoscope Yields Improvements in Cecal Insertion Time and Adenoma Detection Rate: A Retrospective Comparison of Two Colonoscope Brands

Abstract

AbstractBackground and AimsHigh quality colonoscopy remains the cornerstone of colon cancer prevention. Studies have shown that generational advances in colonoscopes result in more favorable clinical outcomes. Performance of various endoscopes is determined using objective quality measures. The aim of this study was to compare these measures between two colonoscope platforms.MethodsThis study is a single center retrospective study of 3,761 patients undergoing initial screening colonoscopy between November 2013 and May 2020 using two different colonoscope platforms (Fujifilm EC-760R-V/L, n=2287 and Olympus CF and PCF 180 series, n= 1474). The primary outcomes measured were cecal insertion time, withdrawal time, and adenoma detection rate.ResultsProcedures completed with the Fujifilm colonoscope had mean cecal insertion times that were 2.01 minutes shorter than procedures completed with Olympus (p<.0001). Procedures completed with Olympus brand colonoscopes had prolonged cecal insertion times (≥10 minutes) nearly three times as often compared to those performed with Fujifilm colonoscopes (p<.0001). Cecal withdrawal times were slightly longer for females performed with Fujifilm colonoscopes, but there was no difference when all procedures were included (p=.09). Procedures completed with Fujifilm colonoscopes had higher adenoma detection rates compared to those completed with Olympus colonoscopes (p<0.001).ConclusionsIn this study, Fujifilm colonoscopes outperformed Olympus colonoscopes in screening colonoscopies with statistically and clinically significant shorter cecal insertion times and higher adenoma detection, though both platforms had similar withdrawal times.
