我国进展期胃癌占多数，治疗效果仍不容乐观。由于胃周血供来源多、需要多处血管根部处理，解剖分离层次多、范围广，淋巴引清扫区域多、操作复杂，消化道重建选择多样，传统2D腹腔镜胃癌根治手术难度大、学习曲线长。随着3D腹腔镜在普外科手术的推广和普及，其立体纵深的全新手术视野，解剖层次更加清晰，操作更加精准，给术者带来全新体验。3D腹腔镜应用于胃癌根治，可以明显缩短术者的学习曲线，尤其在胃癌根治手术中立体脉络化淋巴结清扫、膜解剖指导下的网膜囊切除、完全腹腔镜下消化道重建更显其优势。

The mostgastric cancer cases were advancedin China, the surgical treatment outcomewas still dissatisfactory. Because of more regional vessles ligation, more anatomical planes dissection, more regions of lymph node dissection, more types of reconstructionanastomosis, traditional 2D-laparoscopic radical gastrectomy requires hightechniques and a long learning curve, so is a technically difficult and time-consuming procedure. With the development and popularization of 3D laparoscopic technique in general surgery, it provided a new surgical vision field of tridimensional spatial depth perception and clear anatomic planes, and a new experience of precision operation for the surgeons. 3D laparoscopic radical gastrectomy can shorten a learning curve for novice surgeons, and has more advantages over 2D laparoscopy especially in tridimensional skeletonized lymphadenectomy, membrane anatomy-directed complete buesectomy and total laparoscopic digestive reconstruction.
