Robotic Surgery for Colon and Rectal Cancer.

Abstract

Robotic surgery, used generally for colorectal cancer, has the advantages of a three-dimensional surgical view, steadiness, and seven degrees of robotic arms. However, there are disadvantages, such as a decreased sense of touch, extra time needed to dock the robotic cart, and high cost. Robotic surgery is performed using various techniques, with or without laparoscopic surgery. Because the results of this approach are reported to be similar to or less favorable than those of laparoscopic surgery, the learning curve for robotic colorectal surgery remains controversial. However, according to short- and long-term oncologic outcomes, robotic colorectal surgery is feasible and safe compared with conventional surgery. Advanced technologies in robotic surgery have resulted in favorable intraoperative and perioperative clinical outcomes as well as functional outcomes. As the technical advances in robotic surgery improve surgical performance as well as outcomes, it increasingly is being regarded as a treatment option for colorectal surgery. However, a multicenter, randomized clinical trial is needed to validate this approach.
