“…We even did a comparison with the 2 existing robotic systems ZEUS vs. DaVinci, and laparoscopic surgery, showing no real differences and advantages [13] . One difficulty in comparing laparoscopic surgery and robotic surgery is the added 3D vision with robotic surgery, and one had to wonder if we are really comparing surgical systems or visual systems, as comparison between 2D and 3D systems in laparoscopic surgery has shown an advantage for non-experience or poorer proficient surgeons [14,15] . It seems to me that this is what is captured in the comparison of robotic vs. laparoscopic surgery using the existing system, mostly a 3D effect.…”
