ABSTRACT
Objective To analyze the risk factors of bleeding after endoscopic resection of colorectal polyps.Methods 342 cases of colorectal polyps treated by endoscopic surgery in our hospital were taken as the research objects. The incidence of bleeding after endoscopic surgery was statistically studied. All the patients were divided into bleeding group and no hemorrhage group, with postoperative bleeding as the dependent variable, and related factors which may be induced postoperative bleeding (gender, age, diabetes mellitus, with hypertension and hyperlipidemia history, drinking history, polyp occurrence location, polyp pathology type, polyp size, morphology of colonic polyps, polyp number) as the independent variable to make advanced single factor regression analysis. Then using the logistic regression analysis tool for multivariate analysis.Results The incidence of postoperative bleeding was 7.60% (26/342) in 342 patients. Single factor analysis showed that the bleeding in the proportion of patients with hypertension was higher than that of without complication (P 2.0 percentage higher than that without complication (P 2.0 cm, and polyps were the risk factors of postoperative hemorrhage (P 2.0 cm, polyp morphology of pedicle polyps.
