Solo surgery--with the aid of a robotic assistant.

In the interests of cost containment this study was performed to compare the cost-effectiveness of utilizing a robotic assistant instead of a human assistant. Twelve patients undergoing laparoscopic bladder neck suspension were studied retrospectively. In six of these cases a human assistant was utilized and in another six a robot arm was utilized to hold and manoeuvre the laparoscope and camera. Evaluations have previously been made showing the improved steadiness and clarity of picture when utilizing the robot rather than a human and in this case the length of surgery was compared and the cost of the equipment and all personnel evaluated. The differences in length of surgery between both groups was not statistically significant. The cost of the robotic arm was less than that of human systems. This depends on the volume of surgery and may vary between institutions. In conclusion, a robotic assistant is seen to be a cost-effective device taking the place of the traditional assistant.
