Previous studies have found that patients with large (\u226520 mm) nonpedunculated colorectal polyps have a high prevalence of synchronous colorectal neoplasia. This study investigated synchronous neoplasia in patients with large (\u226520 mm) pedunculated lesions (L-PED), using patients with large nonpedunculated lesions (L-NPED) as controls. <\/p>\n\n\n\n
At least 1 synchronous precancerous lesion was found in 85% of the L-PED group versus 89% of the L-NPED group. The L-PED group had a mean 4.8 synchronous conventional adenomas, 56% had \u22651 synchronous high-risk lesion (advanced adenoma or advanced serrated lesions), 49% had \u22651 synchronous advanced conventional adenoma, and 19% had a synchronous neoplastic lesion \u226520 mm. Overall rates of synchronous polyps, adenomas, and sessile serrated lesions were comparable between the 2 groups, and the L-PED group had a higher rate of synchronous lesions with villous elements (27% vs 16%) and synchronous pedunculated polyps (33% vs 10%).<\/p>\n","protected":false},"excerpt":{"rendered":"
