结直肠息肉内镜摘除术后并发出血的影响因素分析

Influencing factors of hemorrhage after endoscopic polypectomy of colorectal polyps

目的探讨影响结直肠息肉内镜摘除术后并发出血的影响因素。方法选取60例行内镜摘除术治疗的结直肠息肉患者作为研究对象。采用单因素分析和多因素Logistic回归分析结直肠息肉内镜摘除术后出血的影响因素。结果60例患者共切除息肉83枚,发生术后出血11例(18.3%)。单因素分析结果显示,不同摘除息肉数、息肉直径、切除方式、息肉形态,是否合并高血脂的行结直肠息肉内镜摘除术患者术后并发出血比例比较,差异均有统计学意义(P<0.05)。Logistic回归分析结果显示,摘除息肉数目≥3枚(OR=69.000)、合并高血脂(OR=4.145)、息肉直径≥10 mm(OR=6.667)、有蒂息肉(OR=4.846)是结直肠息肉内镜摘除术后并发出血的危险因素(P<0.05)。结论摘除息肉数目≥3枚、合并高血脂、息肉直径≥10 mm、有蒂息肉是结直肠息肉内镜摘除术后并发出血的危险因素。

Objective To explore the influencing factors of hemorrhage after endoscopic polypectomy of colorectal polyps.Methods Sixty cases of colorectal polyps treated by endoscopic polypectomy were selected.Univariate analysis and multivariate logistic regression analysis were used to analyze the influencing factors of hemorrhage after endoscopic polypectomy of colorectal polyps.Results 83 polyps were removed from 60 patients,and 11(18.3%)patients had postoperative hemorrhage.The results of univariate analysis showed that there were significant differences in the proportion of hemorrhage in patients with different removed polyp number,polyp diameter,removal method,polyp shape and whether or not combined with hyperlipidemia(P<0.05).Logistic regression analysis showed that removed polyp number≥3(OR=69.000),combined with hyperlipidemia(OR=4.145),polyp diameter≥10 mm(OR=6.667),and pedicled polyps(OR=4.846)were the risk factors of hemorrhage after endoscopic polypectomy of colorectal polyps(P<0.05).Conclusions Removed polyp number≥3,combined with hyperlipidemia,polyp diameter≥10 mm,and pedicled polyps were risk factors for hemorrhage after endoscopic polypectomy of colorectal polyps.
