AbstractBackgroundParticipation in colonoscopies is an essential aspect of endoscopic training. The purpose of this study was to explore the impact of fellow/trainee participation on colonoscopy outcomes.MethodsThis meta‐analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO). From database inception to July 2022, studies investigating fellow involvement and colonoscopy outcomes were searched across Cochrane library, PubMed, and other databases. The random‐effects model was applied to generate more conservative estimates. Sensitive analysis was conducted to explore whether the result would depend on a particular study. Egger's test and Begg's test were used to estimate the potential for publication bias.ResultsSeventeen studies including 30,062 participants were included. We found that fellow/trainee involvement enhanced the overall rates of adenoma detection and polyp detection (OR = 1.26, 95% CI = 1.14–1.40, p < 0.001; OR = 1.29, 95% CI = 1.02–1.63, p = 0.020, respectively). The mean number of adenoma/polyps per colonoscopy was also higher with fellow/trainee participation (MD = 0.12, 95% CI = 0.08–0.17, p < 0.001; MD = 0.15, 95% CI = 0.02–0.28, p = 0.020, respectively).ConclusionIn addition to its educational purpose, fellow or trainee involvement is associated with beneficial effects on colonoscopy outcomes.
