Yield of repeat forward-view examination of the right side of the colon in screening and surveillance colonoscopy

摘要

Background and AimsColonoscopy is less protective for right-sided colon cancers than distal colon cancers. Repeat right-sided examination has been suggested to increase adenoma detection and right-sided protective effect. Our prospective study assessed the yield of a second forward-view examination of the right colon done immediately after the initial examination.
