BACKGROUND/AIM: The purpose of this study was to reveal the optimal lymph node (LN) dissection in remnant gastric cancer (RGC) patients.
We retrospectively analyzed 46 RGC patients divided into two groups: patients who underwent initial gastrectomy for benign (group B) and malignant (group M) diseases.
Metastasis was more frequently observed at the left (nos. 2, 4sa, 4sb, 10, and 11p/d) and right (nos. 1, 3, 4d, 7, 8a, and 12a) side LNs of RGC in groups M and B. Modified IEBLD scores (frequency of LN metastasis by median survival time of patients with metastatic LNs) were high at station nos. 10 (4.7), 11p/d (4.3/9.9), and 16 (4.3) in group M and nos. 1 (2.1), 7 (1.9) and mesojejunal (3.0) in group B.
After lymphadenectomy for initial gastric cancer, lymphatic flow toward the splenic artery was predominant. Therefore, splenectomy with para-aortic LN dissection is an option.
背景/目的：本研究旨在揭示残胃癌（RGC）患者的最佳淋巴结清扫方式。
我们回顾性分析了46例RGC患者，将其分为两组：因良性疾病（B组）和恶性疾病（M组）接受初次胃切除术的患者。
在M组和B组的RGC患者中，左侧（第2、4sa、4sb、10和11p/d组）和右侧（第1、3、4d、7、8a和12a组）淋巴结转移更为常见。改良IEBLD评分（转移淋巴结患者的中位生存时间的淋巴结转移频率）在M组的第10组（4.7）、11p/d组（4.3/9.9）和第16组（4.3）以及B组的第1组（2.1）、第7组（1.9）和空肠系膜组（3.0）较高。
初次胃癌淋巴结清扫术后，流向脾动脉的淋巴流占主导。因此，脾切除联合主动脉旁淋巴结清扫是一种选择。
