Abstract: 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. Multivariate logistic regression analysis revealed that history of hypertension (P = 0.002, O(R) = 4.654, 95%CI: 1.755 ~ 12.343), polyp size ≥10 mm (P = 0.009, O(R) = 3.637, 95%CI: 1.390 ~ 9.517), location in the right hemicolon (P = 0.016, O(R) = 3.656, 95%CI:1.273 ~ 10.504) were independent risk factors for DPPB. Conclusion Patients with history of hypertension, polyp size ≥10 mm, polyp location in the right hemicolon are prone to DPPB. We should take effective measure to prevent DPPB.
