Ensuring High-Quality Colonoscopy: A Review.

Colonoscopy prevents colorectal cancer through polyp detection and resection. High-quality colonoscopy is important for optimal detection of adenomas and serrated polyps and mitigating the risk of postcolonoscopy colorectal cancer (PCCRC). Optimal bowel preparation quality is also important in reducing PCCRC incidence. Key performance metrics described in this article include bowel preparation adequacy rate, cecal intubation rate, adenoma detection rate, adenomas per colonoscopy, sessile serrated lesion detection rate, and withdrawal time. This article also addresses appropriate colonoscopy indications, proper procedure documentation, and recommended screening and surveillance intervals.
