According to the latest Japanese treatment guidelines for gastric cancer, dissection of the splenic hilar lymph nodes is required during the radical treatment for this condition. This study reports a D2 radical total gastrectomy employing the curettage and dissection techniques, in which the resection of the anterior lobe of transverse mesocolon, vascular denudation and splenic hilar lymph node dissection were successfully completed.展开更多
