Single-port robotic cholecystectomy: results from a first human use clinical study of the new da Vinci single-site surgical platform.

OBJECTIVES To report our results from a first human use clinical study with the da Vinci Surgical single-site instrumentation in patients with gallbladder disease and to perform a retrospective comparison with traditional multiport laparoscopic cholecystectomy. DESIGN Ten patients underwent robotic single-port cholecystectomy performed with the da Vinci Si robot and novel da Vinci single-site instrumentation. Outcomes and operative times were compared with patients undergoing traditional multiport laparoscopic cholecystectomy during the same period. SETTING Tertiary care Veterans Administration hospital. PATIENTS Outpatients older than 18 years with an American Society of Anesthesiologists class of 1 to 3, no prior upper abdominal surgery, and diagnosis of noninflammatory biliary disease. INTERVENTION Single-site robotic cholecystectomy. MAIN OUTCOME MEASURES Operative time, complications up to 30 days, pain scores, and overall satisfaction. RESULTS Nine of 10 patients had completion of robotic single-site cholecystectomy. Average operating room time was 105.3 minutes compared with an average of 106.1 minutes in the standard laparoscopic group. There were no serious adverse events in the robotic surgery group, with an average follow-up of 3 or more months. CONCLUSION Robotic single-port cholecystectomy is feasible and comparable with standard laparoscopic cholecystectomy in the Veterans Administration medical center setting.
