BACKGROUND: The robotic surgical system overcomes many technological obstacles of conventional laparoscopic surgery, and possesses enormous clinical applied potential. The aim of this study was to compare the efficacy of Zeus robot-assisted laparoscopic cholecystectomy with conventional laparoscopic cholecystectomy. METHODS: Forty patients undergoing elective cholecystectomy were randomly divided into two groups. Patients in group A (n=20) underwent Zeus robot-assisted laparoscopic cholecystectomy, and patients in group B (n=20) received conventional laparoscopic cholecystectomy. The parameters on operative field, operative time, the number of actions, the rate of operative errors and minimal trauma were evaluated and compared between the two groups. RESULTS: The number of cleating camera (1.1±1.0 times) and the time of adjusting the operative field (2.2±0.7 minutes) in group A were significantly less than those (4.5±1.5 times) and (7.5±1.2 minutes) in group B. The number of dissection actions (337±86 times) and the rate of operative errors (10%) in group A were less than those (389±94 times), (25%) in group B. The total operation time (104.9±20.5 minutes) and setup time (29.5±9.8 minutes) in group A were significandy longer than those (78.6±17.1 minutes), (12.6±2.5 minutes) in group B. Blood loss and postoperative hospitalization were similar. No postoperative complications occurred in both groups, and open cholecystectomy was performed in each group. CONCLUSIONS: Zeus robot-assisted cholecystectomy inherits the benefits of minimally invasive surgery. The Zeus robotic surgical system is better than conventional laparoscopic technique in controlling the operative field and can be manipulated precisely and stablely though it requires more operative time.
