There is a growing enthusiasm for robotics in many surgical specialities. This enthusiasm is often not supported by data on clinical or cost-effectiveness derived from rigorous evaluation by randomised controlled trials. This is the case for robotic-assisted rectal cancer surgery. Given the expense associated with the robotic systems and the limited evidence to support clinical and economic benefits, it is essential that a proper assessment of this new technology is performed in timely manner before its widespread recommendation or implementation. A randomized trial of robotic-assisted versus standard laparoscopic rectal cancer surgery is now urgently needed.
