Laparoscopic complete mesocolic excision

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.
