摘要In the latest 50 years,the radical dissection rate of colonic cancer and the 5-year survival rate have been improved as colonic surgery techniques improve.In 1991,Jacob performed the first laparoscopic hemicolorectomy in the world,and data from multiple prospective studies have shown no significant difference between laparoscopic and open radical resection of colonic cancer in aspects of postoperative survival and incidence of tumor recurrence.In the year of 2009,Hohenberger suggested the concept of complete mesocolic excision (CME).Clinical data Showed that CME could further improve the postoperative survival and reduce the incidence of tumor recurrence,and it could become the standard surgical procedure following total mesorectal excision.

abstracts全结肠系膜切除术(complete mesocolic excision,CME)作为结肠癌规范化手术的新理念,于2009年由Hohenberger等[1 ]首次提出.CME主要包括:锐性解剖、分离结肠系膜平面与壁层平面,保持完整结肠系膜;清扫区域与中央淋巴结,强调在根部结扎、切断结肠所属的主干血管.
