초록

Background: A number of randomized trials addressing alternative operative and multimodality approaches to gastric cancer have characterized early postoperative morbidity and mortality rates. The aim of this study was to compare mortality and morbidity and disease free survival after D1 and D2 gastrectomy for adenocarcinomas of the stomach Materials and Methods: From June 2006 to January 2012, patients were selected according to information of the cancer administrator center of Ahvaz Jundishapur Medical University. The inclusion criteria were age between 20-85 years and histologically proven adenocarcinoma of the stomach without evidence of distant metastasis. Patients were excluded if they had previous or coexisting cancer or disability disease. In this research, D1 was compared to D2 gastrectomy. Results: 131 patients were randomised, 49 allocated to D1 and 82 to D2 gastrectomy. The two groups were comparable for age, sex, site of tumors, and type of resection performed. The overall post-operative morbidity rate was 17.5%. Complications developed in 14.2% of patients after D1 and in 19.5% of patients after D2 gastrectomy (p=0.07). Postoperative mortality rate was 0.8% (one death); it was 2% after D1 and 0% after D2 gastrectomy. In this research disease free-survival after 3 years was 71.2 % with 63.2% after D1 and 76.8% after D2 gasterctomy. Conclusions: This study indicates that D2 gastrectomy with pancreas preservation is not followed by significantly higher morbidity and mortality than D1 resection. Based on the results of present study, D2 resection should be recommended as the standard surgical approach for resectable gastric cancer.
