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.展开更多

METHODS： Robot-assisted laparoscopic cholecystectomy was performed in 40 patients between May 2004 and July 2005. The operating procedures and a variety of clinical parameters were recorded and analyzed. RESULTS： Forty laparoscopic cholecystectomy procedures were successfully completed with Zeus robotic system. And there were no post-operative complications. Total operating time, system setup time and performing time were 100.3±18.5 min, 27.7±8.8 min and 65.6±18.3 min, respectively. The blood loss and postoperative hospital stay were 30.6±10.2 mL and 2.8±0.8 d, respectively. Camera clearing times and time used for operative field adjustment were 1.1±1.0 min and 2.0±0.8 rain, respectively. The operative error was 7.5%. CONCLUSION： Robot-assisted laparoscopic cholecystectomy following the principles of laparoscopic operation has specific performing essentials. It preserves the benefits of minimally invasive surgery and offers enhanced ability of controlling operation field, precise and stable operative manipulations.展开更多
