ABSTRACT
ObjectiveTo summarize the experience of gastric D2 operation and evaluate the feasibility and safety of peripheral vascular choroid of lymph node dissection.Methods A retrospective study was adopted to analyze the redical D2 operation procedure and operation results 24 advanced gastric cancer cases,summarizing the experience of D2 radical gastrectomy operation for gastric cancer.The number of resected lymph nodes,operation bleeding volume,postoperative complications were analyzed to evaluate the feasibility and safety of operation.Results All 24 cases undergoing D2 radical gastrectomy operation of advanced gastric cancer were successful,and got the R0 resection.A total of 634 lymph nodes were excised in all the cases,averaged 26.42.A totle of 206 metastatic lymph nodes were found,metastasis rate being 32.49％.Operation bleeding volume was averaged 264.58 mL.The postoperative complication rate was 25％,anastomotic bleeding in 1 case,input loop jejunum fistula of esophageal jejunum anastomosis in 1 case,hyperamylasemia and 2 cases reflux esophagitis in 2 cases respectively.Conclusions D2 radical gastrectomy operation of gastric cancer is safe and feasible on the basis of mastering perigastric anatomy and master of lymph node excision technology and anatomical hierarchy separation.
