目的　探讨胃癌术后切端阳性患者的处理方式。方法　选取胃癌根治术后病人 2 3 7例 ,比较切端阳性与其结果之间的关系。结果　发生切端阳性 2 2例 (9.3 % )。肿瘤切端阳性主要与肿瘤的部位 (P =0 .0 1)和肿瘤细胞分化 (P =0 .0 2 )有关 ,切端阳性提示预后不佳。再按术中淋巴转移与否分类统计 ,提示只有N0 期的病人切端阳性会缩短生存期。结论　胃癌术后切端阳性 ,只有N0 期病人需考虑再次剖腹手术 Objective To investigate the treatment of patients with positive posterior incision of gastric cancer. Methods Twenty-three patients with radical gastrectomy were selected, and the relationship between the positive results and the results was compared. The results occurred in 22 cases of positive incision (9.3%). Tumor resection positive mainly with the tumor site (P = 0. 01) and tumor cell differentiation (P = 0. 02), positive posterior tip of the prognosis is poor. Then according to the classification of lymph node metastasis or not, suggesting that only N0 patients cut the positive side will shorten the survival. Conclusion Gastric cancer is positive after incision, only N0 patients need to consider re-laparotomy
