局部进展期胃上部癌的腹腔镜淋巴结清扫策略与应用前景

局部进展期胃上部癌行腹腔镜根治性手术必须遵循与开腹手术相同的淋巴结清扫范围。按从下至上程序化的步骤进行淋巴结清扫，不仅能使手术进程更加顺畅，而且能达到“整块切除”的要求。脾门区淋巴结清扫是腹腔镜局部进展期胃上部癌D2根治术的难点，选择正确的手术入路、熟识脾门区血管解剖类型以及整个手术团队的默契配合有助于缩短该术式的学习曲线。尽管目前对于局部进展期胃上部癌进行腹腔镜淋巴结清扫术仍处于探索性开展阶段，但相信随着更多高级别循证学证据的出现，其有望成为治疗局部进展期胃上部癌的标准清扫术式之一。

Strategy and prospect of laparoscopic lymph node dissection for locally advanced upper-third gastric cancer

Laparoscopic D2 lymphadenectomy for locally advanced upper-third gastric cancer （LAUGC） must follow the same lymph node dissection extent with open surgery. Following the surgical steps can make the operation process more smoothly and achieve en bloc resection. Laparoscopic spleen-preserving splenic hilar lymph node dissection is the difficult point during total gastrectomy for LAUGC. Selecting the right surgical approach, mastering spleen vascular anatomical types, and the cooperation of surgical team can help to shorten the learning curve of the operation. Although laparoscopic lymph node dissection for LAUGC is still in the exploratory stage, we believe that with the emergence of evidence-based medicine, it is expected to become one of the standard operations for LAUGC.
