title: Robotic revisional bariatric surgery: a comparative study with laparoscopic and open surgery.
abstract: BACKGROUND
  Revisional bariatric procedures (RBP) can be technically challenging. While robotics might provide help for complex procedures, the study aim was to report our experience with robotic RBP.
  
  
  METHODS
  From March 2000 to June 2013, 60 consecutive RBP (11 robotic, 21 laparoscopic, 28 open) have been prospectively entered into a dedicated database and reviewed retrospectively. Outcomes have been compared between the three approaches.
  
  
  RESULTS
  The robotic group had fewer complications (0 vs. 14.3% for laparoscopy, vs. 10.7% for open; P > 0.05), but took longer than the other approaches (352 vs. 270 vs. 250 minutes respectively; P < 0.05). There were fewer conversions in the robotic group (0 vs. 14.3% for laparoscopy; P > 0.05), and a significantly shorter hospital stay (6 vs. 8 vs. 9 days, respectively).
  
  
  CONCLUSIONS
  Robotic RBP is feasible and safe, but at the price of a longer operative time. The exact role of robotics remains yet to be defined for this indication in larger studies.
