Zeus robot-assisted laparoscopic cholecystectomy in comparison with manual laparoscopic cholecystectomy / 中国普通外科杂志

ABSTRACT

Objective To evaluate Zeus robot-assisted laparoscopic cholecystectomy. Methods Forty patients were divided into two groups receiving respectively Zeus robot-assisted laparoscopic cholecystectomy (group A, 20 cases), and laparoscopic cholecystectomy (group B, 20 cases). A variety of clinical parameters were evaluated. Compared between these two groups. Results Camera clearing (1.1?1.0) times and time used for operation field adjustment in group A (2.2?0.7) min were significantly less than those in group B (4.5?1.5,7.5?1.2) min. Dissection actions(337?86)times and operative errors(10%) in group A were less than those in group B(389?94) times,25%. The operation time(104.9?20.5) min and setup time (29.5?9.8) min in group A were longer than those in group B (78.6?17.1) min,(12.6?2.5) min. The blood loss,and postoperative hospital stay were similar. There were no postoperative complications in either groups, and conversion to open surgery was done in one each patients. Conclusions Compared with laparoscopic technique, Zeus robotic surgical system offers greater ability of controlling operation field, precise and stable operative manipulations though it requires longer operation time.
