Our results imply that GSC has a wide range of LN metastases, including LN within jejunal mesentery in B-II reconstruction cases, and curable resection may obtain better results. Therefore, we suggest that radical operation for B-I patients needs removal of gastroduodenectomy anastomosis and the above LNs, and that B-II patients need removal of 10 cm of jejunum besides gastrojejunostomy anastomosis, and clearance of LN within its mesentery, in addition to B-I GSC.
