Summary
Robotic Roux-en-Y gastric bypass (rRYGB) is a safe and feasible minimally invasive bariatric surgery. This technique shows good outcomes and minimal complications, making it a promising option for treating severe obesity.
Area of Science:
- Bariatric Surgery
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Minimally invasive bariatric surgery offers superior outcomes compared to open procedures.
- Roux-en-Y gastric bypass (RYGB) is a common bariatric procedure.
- Robotic surgery enhances laparoscopic techniques with improved ergonomics and visualization.
Purpose of the Study:
- To present a standardized Robotic Roux-en-Y gastric bypass (rRYGB) technique.
- To report outcomes from a case series of rRYGB.
- To evaluate the feasibility and safety of rRYGB.
Main Methods:
- Retrospective analysis of a prospective database.
- Inclusion of patients who underwent rRYGB between April 2015 and July 2019.
- Detailed description and illustration of the surgical technique.
Main Results:
- 329 patients underwent rRYGB using da Vinci Si and Xi platforms.
- Mean patient age was 34.4 years, with a median BMI of 44.2 kg/m2.
- Mean console time was 102 minutes, with no conversions and no 30-day readmissions.
Conclusions:
- rRYGB is technically feasible and safe.
- The standardized technique yields good short-term outcomes.
- rRYGB may offer advantages in bariatric surgery with minimal complications.
