Why the study?
The optimal surgical approach—laparoscopic versus robotic—for revisional bariatric surgery remains debated.
Does a robotic approach compared to a laparoscopic approach improve early postoperative outcomes in patients undergoing revisional bariatric surgery?
Population
46 matched patients undergoing revisional bariatric conversion procedures at two centers in Switzerland
Comparison
Robotic conversion approach vs laparoscopic conversion approach
Design
Retrospective matched case-control study
Key result
Robotic revisional bariatric surgery resulted in similar overall early postoperative complication rates compared to the laparoscopic approach (17.4% vs. 13.0%, p=0.681) but longer operative times.

Does a robotic approach compared to a laparoscopic approach improve early postoperative outcomes in patients undergoing revisional bariatric surgery?
Absolute Event Rate: 17.4% vs 13%
p-value: p=0.681
Robotic conversion bariatric surgery is associated with longer operative times but may have a trend toward fewer major complications and reoperations compared to the laparoscopic approach.
Burgard et al. (2026) conducted a case-control in Revisional bariatric surgery (n=46). Robotic conversion approach vs. Laparoscopic conversion approach was evaluated on Early postoperative complications (p=0.681). Robotic revisional bariatric surgery resulted in similar overall early postoperative complication rates compared to the laparoscopic approach (17.4% vs. 13.0%, p=0.681) but longer operative times.
