Background: Super obese (SO) patients with a Body Mass Index (BMI) ≥ 50 kg/m(2) still represent a real anesthesiological and surgical challenge. While the best procedure to perform in this population remains unclear, robotic technology has been proposed to accomplish Roux-en-Y gastric bypass (RYGB). The study aim is to report our experience of robotic RYGB for SO patients and to compare it with open and laparoscopic surgery.
Methods: From July 1997 to March 2014, all consecutive RYGB cases for SO patients were collected in a dedicated database and reviewed retrospectively. Two hundred and fourteen SO patients were operated on: 65 by a robotic approach (30.4%), 54 by a laparoscopic approach (25.2%), and 95 using an open approach (44.4%). Peri- and post-operative data were compared between the three approaches.
Results: There were more male patients in the robotic group, but with a slightly lower BMI. The operative time was longer for the robotic (+27 min) and laparoscopic (+21 min) groups in comparison with the open group (P < 0.05). Overall, there were less reoperations (P < 0.05) and a shorter hospital stay (P < 0.05) in the robotic group in comparison with other groups. Of note there was also a trend in favor of robotics with less conversions (P = 0.08) and less postoperative complications (P ≥ 0.05).
Conclusions: Robotic RYGB can be performed safely in super obese patients with results that compare favorably with laparoscopic and open surgery. However, the robotic approach has a longer operative time. The exact role of robotics for super obese population needs to be clarified in larger and randomized trials before drawing definitive conclusions. Copyright © 2015 John Wiley & Sons, Ltd.
