摘　　要：BACKGROUND Complete mesocolic excision(CME)with central vascular ligation(CVL)was proposed by Hohenberger in 2009.The CME principle has gradually become the technical standard for colon cancer surgery.How to achieve CME with CVL in laparoscopic right hemicolectomy(LRH)is controversial,and a unified standard approach is not yet available.In recent years,the authors’team has integrated the theory of membrane anatomy,tried to combine the cephalic approach with the classic medial approach(MA)for technical optimization,and proposed a cranialmedial mixed dominant approach(CMA).AIM To explore the feasibility of operational approaches for LRH with CME.METHODS In this retrospective cohort study,the clinical data of 57 patients with right-sided colon cancer(TNM stage I,II,or III)who underwent LRH with CME from January 2016 to June 2020 were collected and summarized.There were 31 patients in the traditional MA group and 26 in the CMA group.RESULTS There were no significant differences in baseline data between the two groups.The operation was shorter and the number of lymph nodes dissected was higher in the CMA group than in the MA group,but there was no significant difference in the number of positive lymph nodes,intraoperative blood loss,postoperative exhaust time,feeding time,postoperative hospital stay or postoperative complication incidence.CONCLUSION Our study shows that the CMA is a safe and feasible procedure for LRH with CME and has a unique advantage.
