Application status of robotic surgical system for rectal cancer

With the advantages of stable and three-dimension image and the convenience of surgery manipulation of robotic surgical system, it is widely applied in the surgery of rectal cancer. In this paper, the surgical technique and application change of robotic surgical system are reviewed and its outlook is discussed. Currently, it is reported that robotic surgery for colorectal cancer is safe and feasible. However, no short-term or long-term clinical outcomes are found between the two groups. With the development of surgical instruments and ongoing of large sample studies, robotic surgical system will play a more active role in the treatment of rectal cancer.
