Abstract    The treatment strategies of gastric stump cancer are mainly based on the depth of tumor invasion. For early gastric stump cancer incompatible with endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), the total gastric resection is employed. The extent of lymph node dissection of intramucosal carcinoma is D1/D1+, and D1+/D2 for submucosal carcinoma, D2 for sutures or anastomotic carcinoma. The treatment principle for advanced gastric stump cancer is total gastric resection and D2 lymph node dissection. On the basis of lymph flow and metastatic regulation，D2+ lymph node dissection，16a2b1 resection and essential combined organ resection should be applied to curatively resectable advanced gastric stump cancer of stage T3 or T4.

Key words: gastric stump cancer, lymph flow, lymph node metastasis
