【摘要】 目的:探讨体重指数(body mass index,BMI)与肛瘘术后相关并发症的关系。方法:采取回顾性队列研究方法,连续性纳入2019年1月1日—10月31日于深圳市第二人民医院手术治疗的肛瘘患者,观察术后6个月内肛瘘复发、伤口出血、伤口愈合不良、再次手术等术后并发症情况。采用Logistic回归模型分析BMI与肛瘘患者术后并发症间的关联性。结果:最终共纳入患者457例,平均年龄(36.2±9.2)岁,男性396例(86.65%),肛瘘复发51例(11.16%),术后创面出血11例(2.41%),伤口愈合不良51例(11.16%),再次手术32例(7.00%),合并后共计出现术后相关并发症79例(17.29%)。调整相关混杂因素后,BMI与肛瘘术后并发症之间呈显著关联(OR=1.15,95%CI 1.06～1.24)。高BMI(25.89～34.72 kg/m~2,OR=2.91,95%CI 1.40～6.03)、中BMI(23.32～25.88 kg/m~2,OR=2.44,95%CI 1.14～5.20)与低BMI(15.57～23.24 kg/m~2)相比,发生术后相关并发症的风险增加。结论:BMI增加是肛瘘术后相关并发症的危险因素。更多还原

【Abstract】 Objective:To investigate the relationship between body mass index(BMI) and related complications after anal fistula surgery.Methods:A retrospective cohort study method was adopted to continuously enroll patients with anal fistula who were surgically treated at Shenzhen Second People’s Hospital from January 1 to October 31,2019.The postoperative complications such as anal fistula recurrence,wound bleeding,poor wound healing,and reoperation within 6 months after surgery were observed.Logistic regression model was used to analyze the association between BMI and postoperative complications in patients with anal fistula.Results:A total of 457 patients were enrolled,with an average age of(36.2±9.2) years old,51 recurrences of anal fistula(11.16%),11 postoperative wound bleeding(2.41%),51 poor wound healing(11.16%),32 reoperations(7.00%),and 79 cases(17.29%) of postoperative complications occurred after the merger.After adjusting for confounding factors,there was a significant association between BMI and postoperative complications of anal fistula(OR=1.15,95% CI1.06-1.24).Compared with low BMI(15.57-23.24 kg/m~2),high BMI(25.89-34.72 kg/m~2,OR=2.91,95% CI 1.40-6.03),medium BMI(23.32-25.88 kg/m~2,OR=2.44,95% CI 1.14-5.20) increased the risk of postoperative complications.Conclusion:Elevated BMI is a risk factor for postoperative complications of anal fistula.更多还原
