摘要根治性切除仍是可能治愈胃癌的主要手段。淋巴结转移是胃癌常见的转移方式，局部淋巴结受累及的风险随着胃壁的浸润深度而增加。规范的淋巴结清扫是改善胃癌患者预后的重要步骤。目前，远端胃癌D 2根治术是局部进展期胃癌的标准手术方式。因此，在4K腹腔镜平台基础上，普及、推广胃癌根治术淋巴结清扫手术操作的规范化与标准化，对提升广大胃癌外科医师的治疗水平、为患者提供"同质化"的诊断与治疗服务具有重要意义。

abstractsRadical resection is still the main method to cure gastric cancer. Lymph node metastasis is a common metas-tatic pattern of gastric cancer. The risk of local lymph node invasion increases with the tumor invasion depth of gastric wall. Standard lymph node dissection is an important step to improve the prognosis of patients with gastric cancer. At present, D 2 radical gastrectomy is the standard procedure for locally advanced gastric cancer. Therefore, it is of great significance to popularize the standardization of lymph node dissection in radical gastrectomy on the basis of 4K laparoscopic platform, which can improve the treatment level of gastric cancer surgeons and provide "homogenized" diagnosis and treatment services for patients.
