High-Volume Colonoscopy Predicts Higher Cecal Intubation Rates and Lower Perforation Risk, but Not Higher Detection or Cancer Prevention

In a systematic review and meta-analysis encompassing 27 studies with 11,276,244 colonoscopies, there was no association of procedure volume with adenoma detection rate (ADR) nor prevention of postcolonoscopy cancer. The cecal intubation rate increased with each additional 100 annual procedures (odds ratio [OR], 1.17). Overall adverse events trended lower with each 100 annual procedures (OR, 0.95; 95% confidence interval, 0.90-1.00). The risk of perforation appeared more clearly reduced, based on two large studies that had specifically examined this, with 8% and 4% risk reductions per 100 additional annual procedures.
