Background. Laparoscopic cholecystectomy has been the gold standard treatment for symptomatic cholelithiasis for more than 3 decades. Robotic techniques are gaining traction in surgery, and recently, the Senhance™ robotic system was introduced. The system offers advantages over other robotic systems such as improved ergonomics, haptic feedback, eye tracking, and usability of standard laparoscopic trocars and reusable instruments. The Senhance was evaluated to understand the feasibility, benefits, and drawbacks of its use in cholecystectomy. Study Design. A prospectively maintained database of the first 20 patients undergoing cholecystectomy with the Senhance was reviewed at a single hospital. Data including operative time, console time, set up time, and adverse events were collected, with clinical outcome and operative time as primary outcome measures. A cohort of 20 patients having laparoscopic cholecystectomy performed by the same surgeon was used as a comparator group. Results. The 2 groups had comparable demographic data (age, sex, and body mass index). In the Senhance group, 19 of the 20 procedures (95%) were completed robotically. The median (interquartile range) total operating, docking, and console times were 86.5 (60.5-106.5), 11.5 (9-13), and 30.8 (23.5-35) minutes, respectively. In the laparoscopic group, the median (interquartile range) operating time was 31.5 (26-41) minutes. Postoperatively, only one patient had a surgical complication, namely a wound infection treated with antibiotics. Conclusion. Our results suggest that Senhance-assisted cholecystectomy is safe, feasible, and effective, but currently has longer operative times. Further prospective and randomized trials are required to determine whether this approach can offer any other benefits over other minimally invasive surgical techniques.
