胃癌是最常见、病死率最高的恶性肿瘤之一。当前，外科手术治疗是胃癌最主要的治疗方法，根治性的切除是胃癌病人获得治愈的唯一手段。据报道，D2淋巴结清扫术将使胃癌病人在生存时间上获益，对于进展期胃癌，D2手术被广泛地接受和应用。淋巴结清扫是胃癌根治性手术中最重要的部分，同时连同淋巴一起整块的切除是胃癌手术的难点所在。

Abstract    Gastric cancer is one of the most common malignancies and a leading cause of cancer death. Nowadays, surgical management is the major treatment method for gastric cancer. Complete resection is still the only treatment for patients with gastric cancer. It was reported that improved prognosis was gotten in patients with gastric cancer who underwent D2 lymphadenectomy. D2 radical resection has been widely performed for advanced gastric cancer. Lymphadenectomy is the most important part of curative resection, but safe en bloc lymph node dissection is also the most difficult.
