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.
