摘要腹腔镜胃癌切除术已被广泛应用于胃癌外科治疗领域，腹腔镜胃癌手术指征也在不断扩展。基于CLASS-01的研究结果，腹腔镜远端胃癌根治术已作为局部进展期胃癌的标准推荐手术方式之一。随着胃上部癌和食管胃结合部腺癌的发病率不断增加，近端胃切除术和全胃切除术的比例逐渐上升。但是，由于肿瘤复发风险高和术后严重胃酸反流症状，近端胃切除术的手术指征越来越严格。考虑到腹腔镜的微创优势，对于符合手术指征的患者，腹腔镜近端胃切除术仍不失为一种可选择的手术方式。众所周知，淋巴结清扫是标准胃癌根治术的关键步骤，根据日本胃癌协会(JGCA)胃癌治疗指南，近端胃癌根治术的标准手术方式为近端胃切除术联合D 1(第1、2、3a、4sa、4sb、7组淋巴结)或D 1＋(D 1淋巴结＋第8a、9、11p组淋巴结)淋巴结清扫。笔者就近端胃癌根治术淋巴结清扫范围进行阐述，并对腹腔镜近端胃癌淋巴结清扫技术标准进行解读。

abstractsLaparoscopic gastrectomy has been widely applied in the surgical treatment for gastric cancer. The indications of laparoscopic gastrectomy for gastric cancer are also expanding. Based on the results of CLASS-01 study, laparoscopic distal gastrectomy is one of standard recommended surgical procedures for locally advanced gastric cancer. With the increased incidence of proximal gastric cancer and adenocarcinoma of esophagogastric junction, the proportion of total and proximal gastrectomy is gradually increasing. However, in consideration of tumor recurrence risk and severe gastroesophageal reflux symptoms after operation, the indication for proximal gastrectomy is more rigorous. Considering the minimally invasive advantage of laparoscopy, laparoscopic proximal gastrectomy is still an alternative surgical method for patients with surgical indications. It is well known that lymphadenectomy is the key procedure in stan-dard radical gastrectomy for gastric cancer. According to the Japanese gastric cancer treatment guideline of Japanese Gastric Cancer Association (JACA), the standard surgery of proximal gastrectomy is proximal gastrectomy combined with D 1 (No.1, 2, 3a, 4sa, 4sb, 7) or D 1+ (D 1+ No.8a, 9, 11p) lymphadenectomy. The authors describe the extent and procedure of lymphadenectomy and interpret technical standards for laparoscopic proximal gastrectomy.
