中文摘要：

目的探讨超重对于胃癌根治术近期疗效的影响。方法回顾性收集2009年1月至2012年12月于我科行胃癌根治术的患者166例（超重组102例,非超重组64例）,比较两组患者术中、术后以及近期生存情况。结果超重组手术时间明显长于非超重组[（237.70±59.16）min vs.（210.55±54.49）min,P〈0.05））,术中出血量亦明显高于非超重组[（346.41±223.63）mL vs.（276.77±155.46）mL,P〈0.05）];两组的术中总淋巴结清扫数、肛门排气时间、进食时间、术后住院时间以及术后并发症的差异均无统计学意义。超重组和非超重组的3年生存率分别为76.8%和65.1%,差异无统计学意义（P〉0.05）。结论超重会延长手术时间和增加术中的出血量,但不会影响手术的近期疗效。

英文摘要：

Objective To investigate the impact of overweight on short-term outcomes of radical gastrectomy on gastric cancer（GC）.Methods We collected retrospectively the clinical data of 166 GC patients（102overweight and 64 non-overweight ones）who had undergone radical resection in our department from January 2009 to December 2012.We then compared the two groups in intraoperative and postoperative parameters as well as short-term survival rate.Results The operation time of overweight GC patients was longer than that of nonoverweight GC ones（237.70±59.16）min vs.（210.55±54.49）min（P〈0.05）;the intraoperative blood loss of overweight GC patients was more than that of non-overweight GC patients（346.41±223.63）mL vs.（276.77±155.46）mL（P〈0.05）.There were no significant differences between the two groups in the number of retrieved lymph nodes,the first flatus time,the first time to have liquid diet,postoperative hospitalization time,postoperative complications,or postoperative 3-year overall survival rate（76.8% and 65.1%）（all P〉0.05）.Conclusion Overweight is associated with longer operation time and more intraoperative blood loss,but it does not affect the short-term outcomes of the operation.
