Abstract
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. Key words: Colonic Neoplasms; Laparoscopy; Lymph Node Excision
