【摘要】 目的探讨体质量指数(body mass index,BMI)对腹腔镜结直肠癌手术结果的影响。方法选取2018年5月至2018年12月在陕西省人民医院行腹腔镜结直肠癌手术的住院病人200例作为研究对象,计算BMI,按照世界卫生组织对超重的判断标准,将病例分为BMI≥25 kg/m~2的高BMI组50例,BMI<25 kg/m2的低BMI组150例,统计方法使用t检验、非参数检验、χ~2检验,相关性分析使用Pearson或Spearman相关性分析;危险因素分析使用Logistic回归分析。结果两组一般资料相比,腰围差异有统计学意义(t=9.973,P<0.05);两组手术结果相比,高BMI组的手术时间更长(t=4.355、P<0.05)、术中出血量更多(t=9.070、P<0.05);BMI与手术结果相关性分析表明,BMI与手术时间(r=0.331、P<0.05)、术中出血量(r=0.596、P<0.05)呈正相关;术后总体并发症的Logistic回归分析结果显示,BMI不是术后总体并发症的危险因素(P>0.05)。结论 BMI高的病人与BMI低的病人相比较,腹腔镜结直肠癌手术的手术时间更长、术中出血量更多。更多还原

【Abstract】 Objective To investigate the effect of body mass index(BMI)on surgical outcomes of laparoscopic surgery for colorectal cancer.Methods A total of 200 inpatients who underwent laparoscopic colorectal cancer surgery in Shaanxi Provincial People′s Hospital from May 2018 to December2018 were selected as the study subjects.BMI was calculated.According to the World Health Organization(WHO)criteria for overweight,the patients were divided into high BMI group(50 cases)with BMI≥25 kg/m~2 and low BMI group(150 cases)with BMI<25 kg/m~2.Statistical methods included t test,nonparametric test,χ~2 test,Pearson or Spearman correlation analysis;Logistic regression was used for risk factor analysis,and P<0.05 was considered statistically significant.Results There was significant difference in waist circumference(t=9.973,P<0.05)between the two groups in general data;compared with surgical results,the surgical duration(t=4.355,P<0.05)and intraoperative blood loss(t=9.070,P<0.05)in high BMI group were higher than those in low BMI group;correlation analysis between BMI and surgical results showed that BMI was positively correlated with surgical duration(r=0.331,P<0.05)and intraoperative blood loss(r=0.596,P<0.05);Logistic regression analysis of overall postoperative complications showed that BMI was not a risk factor for overall postoperative complications(P>0.05).Conclusion Compared with patients with low BMI,patients with high BMI have longer operation time and more bleeding during laparoscopic colorectal cancer surgery.更多还原
