体质量指数及腰围不影响胃癌病人的短期手术结局

Body mass index and waist circumference do not affect early surgical outcomes in gastric cancer patients with D2 lymphadenectomy

目的:探讨肥胖及腹型肥胖对于胃癌病人短期手术结局的影响。方法:回顾性收集经腹胃切除+D2淋巴结清扫术的226例胃癌病人临床资料。手术前分别测量身高、体重和腰围,根据体质量指数(BMI),将病人分为非肥胖组、超重组和肥胖组;根据腰围,将病人分为非腹型肥胖组、腹型肥胖组。比较各组病人术中出血量、手术时间、术后住院天数、术后胃周淋巴结检出数及术后并发症。结果:非肥胖组、超重组、肥胖组3组间的平均手术时间(P=0.451)、平均术中出血量(P=0.949)、平均术后住院天数(P=0.745)、平均总淋巴结检出数(P=0.165)无统计学差异。非腹型肥胖组与腹型肥胖组间的手术时间(P=0.886)、平均术中出血量(P=0.596),平均术后住院天数(P=0.555)、平均总淋巴结检出数(P=0.209)亦无统计学差异。术后27例发生早期并发症,发生率为12.3%,其在BMI非肥胖组、超重组、肥胖组(P=0.394)间及非腹型肥胖组、腹型肥胖组(P=0.846)间均无统计学差异。结论:BMI及腰围不影响胃癌病人的手术时间、出血量、住院天数、淋巴结检出数及早期术后并发症。

Objective To explore the effect of obesity and abdominal obesity on early surgical outcomes for patients with gastric cancer.Methods A total of 226 consecutive gastric cancer patients who underwent a potentially curative gastrectomy were included in the study.According to BMI,they were assigned to three groups： normal body weight group,overweight group and obesity group.According to waist circumference,they were assigned to two groups： normal waist circumference group,;abdominal obesity.Parameters such as intraoperative blood loss,time of operation,postoperative hospital stay,the numbers of lymph nodes retrieved and surgical and nonsurgical complications were recorded and compared among groups.Results According to BMI,the mean values of the intraoperative blood loss（P=0.949）,length of operation（P=0.451）,the numbers of lymph nodes retrieved（P=0.165） and length of stay in the ward（P=0.555）were not significantly different among three groups.According to waist circumference,the mean values of the intraoperative blood loss（P=0.596）,length of operation（P=0.886）,the numbers of lymph nodes retrieved（P=0.209） and length of stay in the ward（P=0.209） were were not significantly different between the two groups.No significant differences were found with regard to the early surgical complications in these BMI groups and waist circumference groups.Conclusions our study reveals that BMI and waist circumference were not associated with early surgical outcomes for patients with gastric cancer.
