胃上部癌腹腔镜脾门淋巴结清扫术的研究进展

Updates in the research of laparoscopic splenic hilar lymphadectomy for upper-third gastric cancer

随着胃上部癌腹腔镜全胃切除术的不断成熟,该术式已逐渐被经验丰富的外科医师接受.不同于腹腔镜远端胃切除术中已经规范化、程序化的D2淋巴结清扫,胃上部癌腹腔镜脾门淋巴结清扫的指征和方式尚存争议,阻碍其推广的问题涉及是否联合脏器切除、手术路径选择以及对脾门区血管多变的解剖结构的认识等.同时,腹腔镜脾门淋巴结清扫的安全性和远期疗效也有待更多高级别循证医学证据的进一步证实.随着手术理念和技术的不断进步,胃上部癌腹腔镜脾门淋巴结清扫术将会不断成熟.

Laparoscopic surgery for upper-third gastric cancer has gradually been accepted by experienced surgeons as the mature of this technique.Different from the standardized and programmed D2 lymph node dissection in Laparoscopy-assisted Billroth Ⅰ gastrectomy,the indications and methods for laparoscopic splenic hilar lymphadectomy in the upper-third gastric cancer remains controversial.Unsolved problems include joint organs resection,appropriate surgical approach selection and variable vascular anatomy of the splenic hilum.Meanwhile,the long-term efficacy and safety of laparoscopic splenic hilar lymphadectomy for the upper-third gastric surgery need to be confirmed by evidence-based medical trials.With the advance of the theory and clinical practice,laparoscopic splenic hilar lymph node dissection will continue to progress.
