Objective To explore the relative factors affecting abdominal infection after operation for gastric cancer. Methods From June 2011 to June 2014,200 patients with gastric cancer admitted into our hospital for surgeries were selected.Ten cases with abdominal infection were classified into observation group and the rest was categorized into control group.The factors influencing abdominal infection after gastric cancer surgeries were summarized. Results There were statistical differences in anemia,hypoalbuminemia,surgical therapeutic method and neoplasm staging index,with siginificant difference between two groups (P<0.05).The risk factors influencing abdominal infection after gastric cancer surgeries included anemia,hypoalbuminemia, stage Ⅲ based on TNM classification,and D3 eradication of gastric cancer surgery with statistical differences (P<0.05). Conclusion Targeting on relative factors influencing on abdominal infec-tion after gastric cancer surgery,it is necessary to timely correct primary symptoms and reduce lymph node dissection in order to lower down the incidence of complications and effectively improve prognosis.%目的：探讨胃癌手术后影响腹腔感染的相关因素。方法选取2011年6月~2014年6月我院收治的200例胃癌手术患者，将10例腹腔感染患者划归为观察组，其余归入对照组，总结胃癌手术后影响腹腔感染的因素。结果两组患者在贫血症状、低蛋白血症、手术治疗方式以及肿瘤分期指标比较，差异有统计学意义(P<0.05)，患者的贫血症状、低蛋白血症、肿瘤TNM分级芋期以及胃癌D3根除手术属于胃癌术后影响腹腔感染的危险性因素，两组比较，差异有统计学意义(P<0.05)。结论针对胃癌手术后影响腹腔感染相关因素，需要及时纠正原发症状，减少淋巴结清扫，从而降低并发症发生率，有效改善预后情况。
