Background: Robotic technique has been proposed to overcome the limitations of laparoscopic surgery. In this study, we aimed at determining whether robotic complete mesocolic excision (CME) for right-sided colon cancer can be safe and effective as conventional right hemicolectomy (CLRH). Materials Methods: Between February 2015 September 2017, patients undergoing CME CLRH with curative intent were included. Patient characteristics, short-term histopathological outcomes compared between...
