Core Tip
Core tip: In western countries, generally all colorectal polyps are removed, including serrated polyps, except rectosigmoid hyperplastic polyps ≤ 5 mm in size. However, no treatment strategy has been developed for colorectal serrated polyps in Asian countries. Hence, in this review, we described the clinicopathological features of colorectal serrated polyps and proposed to remove hyperplastic polyps and sessile serrated lesions ≥ 6 mm in size, and traditional serrated adenomas of any size by narrow-band imaging observation.
