近年来,胃上部癌的发病率呈逐年上升的趋势~([1-2])。根据《日本胃癌治疗指南》的规定,对于进展期胃癌行根治性全胃切除术时必须清扫脾门淋巴结~([3])。但是,由于脾门区的血管解剖较为复杂,位置深在,空间狭小,并且常常被覆较多的网膜脂肪组织,使得保留脾脏的脾门淋巴结清扫一度成为胃癌外科手术的难点之一。直至2008年韩国学者Hyung等~([4])才首次报道了腹腔镜保留脾脏的脾门淋 In recent years, the incidence of upper gastric cancer showed a trend of rising year by year ~ ([1-2]). According to the “Guidelines for the Treatment of Gastric Cancer in Japan”, splenic lymph nodes must be dissected during radical gastrectomy for advanced gastric cancer. [3] However, due to the more complicated vascular anatomy of the splenomembranous region, the location is deep, the space is narrow, and often covered by omental adipose tissue, making spleen lymph node dissection retained spleen once became one of the difficulties of gastric cancer surgery. Until 2008, Korean scholar Hyung et al. ([4]) reported for the first time laparoscopic splenic lymphoid spleen retention
