腹腔镜胃上部癌保脾手术的脾门区淋巴结清扫技术

脾门区淋巴结是进展期胃上部癌患者行D2根治术中必须清扫的淋巴结。随着外科技术的进步和治疗理念的更新．保脾的脾门区淋巴结清扫术目前已逐渐被外科医师所接受。由于脾脏位置深在．脾血管解剖变异多，使得腹腔镜保脾的脾门区淋巴结清扫术操作难度大。术者一方面要把握手术适应证：另一方面应采取合理的手术人路和程序化的手术操作步骤．同时必须熟识腹腔镜下脾门区的血管解剖特点．以血管解剖为基础．才能更好地完成腹腔镜下保脾的脾门淋巴结清扫术。

Laparoscopic spleen-preserving splenic hilar lymph node dissection for proximal gastric cancer

Splenic hilar lymph node （LN） should be removed in a D2 lymph node dissection for the advanced proximal gastric cancer. After improving the surgical technology and renewing treatment concepts, spleen-preserving splenic hilar LN dissection has been accepted by more and more surgeons. Because the anatomy position of spleen is very deep, and the splenic vessel is various, laparoscopic spleen- preserving splenic hilar LN dissection may be more difficult. In order to do better in laparoscopic spleen-preserving splenic hilar LN dissection, surgeons should choose the suitable patients; take reasonable surgical approach and surgical steps. Moreover, knowing the anatomy variance well of splenic vessel is also very important too.
