The complete mesocolic excision (CME), first described by Hohenberger et al. involves dissection in the embryological plane between mesocolic and retroperitoneal fascia to remove an intact envelope of mesocolon, central vascular ligation (CVL), resection of sufficient length of proximal and distal bowel, and adequate clearance of draining lymph nodes including apical nodes [1,2,3]. The CME has the advantages of improved specimen quality and superior lymph node yield [1,2]. Better oncological outcomes including lower local recurrence rate and superior long term survival has been demonstrated with CME [1,2,3]. Performing Laparoscopic CME is technically challenging and not routinely performed by many. Recent systematic review and meta-analysis showed improved specimen quality and superior perioperative results [4,5] and non-inferior long term oncological outcomes with Laparoscopic CME [4].

腹腔镜完整结肠系膜切除术 - 一种从内侧到外侧和从尾部到颅侧的组合方法

完整的结肠系膜切除术 (CME)，首先由 Hohenberger等人描述. 包括在结肠系膜和腹膜后筋膜之间的胚胎平面解剖以去除结肠系膜的完整包膜，中央血管结扎（CVL），切除足够长度的近端和远端肠，以及充分清除引流淋巴结，包括顶端淋巴结 [1,2 ,3]。CME 具有提高标本质量和优越淋巴结产量的优势 [1,2]。CME 已经证明了更好的肿瘤学结果，包括更低的局部复发率和更长的长期生存率 [1,2,3]。执行腹腔镜 CME 在技术上具有挑战性，许多人并不经常执行。最近的系统回顾和荟萃分析显示，腹腔镜 CME 可提高标本质量和卓越的围手术期结果 [4,5] 以及非劣效的长期肿瘤学结果 [4]。
