Dose complete mesocolic excision contribute to improving the clinical outcomes of colon cancer?

For new surgical procedures to become widely adopted, first of all, technical safety has to be confirmed. After that, these procedures have to be shown to be superior in long-term outcome compared with established procedure. In terms of complete mesocolic excision (CME), the technical safety seems to be almost considered acceptable. To date, there is still no conclusive data about which approach is better among open surgery or laparoscopic surgery or robotic surgery or single port surgery. Additionally, there are few reliable data in terms of long-term outcome of CME from high quality prospective study, which might confuse a lot of surgeons when deciding to perform CME or not.
