Risk Factors of Post-polypectomy Delayed Hemorrhage / 中山大学学报(医学科学版)

ABSTRACT

@#【Objective】To analyze the risk factors of delayed hemorrhage after colon polyp resection.【Methods】We retrospectively analyzed the clinical data of patients who underwent endoscopic polypectomy between January 2010 and December 2018，in which 106 patients with delayed hemorrhage were hemorrhage group，while 3 856 patients who did not bleed were the controlled group，and Logistic regression model was applied to screen the risk factors of hemorrhage after polyp resection.【Results】Of the 3 962 patients included in the study，106 had delayed post polypectomy hemorrhage， the hemorrhage rate being 2.68%. 89.6% delayed hemorrhage occurred within 3 days after polypectomy. Logistic regression analysis showed that the difference of polyp size，complicated hypertension，combined with chronic nephropathy，aspirin drug history and warfarin drug history in hemorrhage group and control group was statistically significant（P values were 0.011，0.009，0.028，0.001，0.023，respectively）.【Conclusion】The size of polyps，comorbidity of hypertension，chronic renal disease ，application of aspirin and warfarin were considered to be independent risk factors for post-polypectomy delayed hemorrhage，most of hemorrhage occurred within 3 days. According to the risk factors of patients，we may predict the risk of delayed hemorrhage.
