Abstract: Right colon cancer is a kind of clinically common colorectal cancer. Surgical resection is the main treatment and the only curative method for patients. Improvement of surgical methods in recent years is one of the hotspots in the surgical treatment of colorectal cancer. There are controversies in laparoscopic surgery or traditional open surgery, intestine resection extent, D3 radical surgery or complete mesocolic excision, selective arterial guidance or venous guidance, pyloric lymph nodes (No.6 group lymph nodes) dissection, and most of the issues are currently lacking of prospectively randomized controlled trials. Therefore, this article discusses the above problems. At the same time, in view of the complicated operation of right hemicolectomy, and the greater risk of surgery, the author consulted the relevant literature and combined his clinical experience to introduce the key techniques of the operation.
