Summary
Robotic-assisted bariatric surgery uptake tripled, showing largely equivalent short- and long-term outcomes compared to laparoscopic methods. However, robotic surgery was linked to higher reoperation rates at seven years.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technology
- Bariatric Surgery Outcomes
Background:
- Robotic-assisted surgery adoption in bariatric procedures is rising.
- Comparative safety data between robotic and laparoscopic approaches remain limited.
Purpose of the Study:
- To assess the increasing utilization of robotic-assisted bariatric surgery.
- To compare the safety and efficacy of robotic versus laparoscopic bariatric surgery.
Main Methods:
- Retrospective analysis of a national Medicare claims database (2012-2020).
- Inclusion of adult patients undergoing sleeve gastrectomy or gastric bypass.
- Instrumental variables analysis for risk-adjusted outcomes up to 7 years post-surgery.
Main Results:
- Robotic approach adoption surged significantly for both sleeve gastrectomy (250%) and gastric bypass (361%).
- No significant differences in 90-day outcomes or 7-year complication rates were observed.
- Robotic surgery was associated with a higher 7-year reoperation rate for both procedures.
Conclusions:
- Robotic-assisted bariatric surgery use more than tripled over a decade.
- Short- and long-term outcomes were generally comparable between robotic and laparoscopic approaches.
- Increased reoperation rates warrant further investigation for robotic bariatric surgery.
