淋巴结转移是影响残胃癌预后的重要因素，残胃癌治愈性切除的累积5 年存活率可达50%以上。残胃癌的淋巴结转移率，N0：76%，N1：18%，N2：18%，N3：6%。残胃癌的淋巴结转移部位除胃周的第1 站外，脾门、脾动脉干淋巴结，肠系膜根部淋巴结、腹主动脉周围淋巴结和下纵隔淋巴结均有高频度的转移率。熟知残胃的淋巴流向和淋巴结转移规律，积极、合理的淋巴结清扫，有助于改善残胃癌的预后。

Pattern of lymph node metastasis in gastric stump carcinoma HU Xiang. Department of General Surgery, the First Affiliated Hospital, Dalian Medical University, Dalian 116011, China Abstract Lymph node metastasis is a crucial factor influencing the prognosis of gastric stump carcinoma. The overall 5-year survival rates are up to 50% for curative resection cases of gastric stump carcinoma. Incidence of lymph node metastasis for gastric stump carcinoma is N0 76%, N1 18%, N2 18%, N3 6%. Except for the metastasis in N1 regional lymph nodes around the stomach, the lymph nodes around the area of splenic hilum, splenic artery, the radix of jejunal mesentery, abdominal aorta and infradiaphragm show high metastatic incidence. Mastering the particular lymph flow and pattern in lymph node metastasis, appropriate lymphadenectomy will contribute to improve the prognosis of gastric stump carcinoma.
