[Abecedary of colonic polyps]

Colonic polyps are very common in the general population. Some polyps present a cancerization risk and their screening and management by endoscopy reduce the risk of colorectal cancer. Other polyps do not need specific follow-up. There are different types of polyps whose classification has been updated over the last ten years. Serrated polyps now intersect hyperplastic polyps, sessile serrated adenomas and traditional serrated adenomas. Current recommendations are to resect and histologically analyze each colonic polyp to define a personalized endoscopic surveillance strategy. Some colonic polyposis syndromes require management in a specialized center.
