腹腔镜右半结肠癌淋巴结清扫范围目前东西方的指南仍然存在较大的差异。近年来，随着全结肠系膜切除(CME)理念的提出和完善，以及腹腔镜技术在结肠癌手术中的广泛应用，许多结直肠专科医生认为腹腔镜CME手术应该成为右半结肠的"标准"术式。CME原则在右半结肠外科手术入路和标本质量控制方面作用巨大，沿胚胎学解剖层面的腹腔镜外科手术逐步成为规范，在理论上完整切除了可能存在转移、播散的病变肠管系膜，最大限度地清扫了区域淋巴结。这样的切除和淋巴清扫范围并未明显增加手术相关并发症，且能提高生存时间。但是，按照CME原则的根治术在手术风险以及肿瘤学获益方面的优势主要来源于回顾性研究的结果。因此，需要更高级别循证医学证据的研究结果来进一步证实目前的观点或共识。

There are still significant differences between Western and Eastern in terms of current guidelines for the criterion of lymphadenectomy in laparoscopic right colectomy for colon cancer. In recent years, with the proposal and improvement of complete mesocolic excision (CME) and the wide application of laparoscopic technique in colon cancer surgery, many colorectal specialists believe that laparoscopic CME surgery should become a " standard" operation for the right colon cancer. The CME principle plays critical role in the surgical approach and quality control of the right colectomy. Based on CME principle, anatomical level should always be kept during laparoscopic surgery, which ensured the radical resection of metastatic and disseminated enteric mesenteric membrane, as well as regional lymph nodes. Such excision and lymph node dissection did not significantly increase the complications related to the operation, and could improve postoperative survival. However, due to the limitation of retrospective studies, its advantages of surgical safety and oncology benefit are unconvincing. The findings of high level evidence-based medical evidence are still needed in the future.
