Objective To analyze risk factors for delayed postpolypectomy bleeding(DPPB) of colorectal polyps. Methods We reviewed 1 098 patients(2 169 polyps) who accepted endoscopic polypectomy from July 2014 to July 2017. Evaluate the risk factors for DPPB. Results DPPB occurred in 18(1.6%) cases. Univariate analysis revealed that history of hypertension(P = 0.007), polyp size ≥10 mm(P = 0.009), right hemicolon location(P = 0.015) and adenomatous polyp(P = 0.045) were risk factors for DPPB.
