Abstract

Laparoscopic right colectomy is currently considered the standard treatment for right colon cancer. After excision of the right colon, minimally invasive options for ileocolonic anastomosis include extracorporeal anastomosis (EA) and intracorporeal anastomosis (IA). However, the choice of anastomotic technique remains debated. As the entire IA is performed in the abdominal cavity, it is known for its advantages of a faster intestinal recovery and small incision. However, IA is time-consuming and technically difficult, limiting its widespread use. Recently, the robotic approach has increased the adoption of intracorporeal anastomotic techniques owing to the benefits of endowrist-articulated instruments and staplers. Except for a small incision and faster bowel recovery, the outcomes of the two anastomoses methods are inconsistent. To date, there has been no clear conclusion regarding whether IA or EA should be used to treat right colon cancer. This review aimed to investigate the current evidence relating to intraoperative outcomes and shortterm postoperative results between both anastomotic approaches.
