Li Xinxiang, Department of Colorectal Surgery, Cancer Hospital of Fudan University: This kind of surgery can be done either openly or laparoscopically to achieve radical cure. Of course, laparoscopic surgery is less traumatic and faster recovery, but it requires higher technical requirements. The advantages of laparoscopic surgery can only be realized by mature surgeons, and there is a lack of radical resection for immature surgeons.
