Polypectomy Rate: A Surrogate for Adenoma Detection Rate Varies by Colon Segment, Gender, and Endoscopist

On the basis of a review of findings from screening colonoscopies, overall PR correlates with ADR for the entire colon, but PR and ADR correlate most strongly for the proximal colon, where many adenomas can be missed and interval cancers develop. The correlation between PR and ADR is weaker for women than men and for distal colon. If PR is used as a surrogate for ADR, colon location and patient sex should be considered.
