We report a case of laparoscopic cholecystectomy that was performed using a robotic surgical system. A 70-year-old woman underwent laparoscopic robotic cholecystectomy ZEUS, the robotic system used in our study, has three interactive robotic arms fixed to the side of the operating table. The arms are controlled by the surgeon, who sits at a remote computer console. The surgeon's movements can be scaled down, and tremor is filtered out. The robotic-assisted laparoscopic cholecystectomy was completed in 42 min. The time to set up the robot was 22 mins. All of the surgically reproducible robotic maneuvers were performed without any particular difficulty. The robotic movements were stable, accurate, and reliable, as well as easy to control with precision. Our preliminary experience indicates that robotic laparoscopic cholecystectomy is safe and can be as fast as conventional laparoscopic cholecystectomy. However, further clinical applications of robotic surgery are needed to confirm this observation.
