Introduction

While laparoscopy remains the predominant approach for bariatric procedures, recent national data suggest that robotic platforms are now used in up to 35% of bariatric surgeries (Spurzem et al., Surg Obes Relat Dis 21:372-81, 2025); (Spurzem et al., Surg Endosc 38:6294-304, 2024). As robotic surgery continues to gain popularity, it is important to understand the potential advantages it may offer over conventional laparoscopy. Our aim in this study is to evaluate the short- and long-term outcomes of primary robotic gastric bypass surgery.

Methods

This retrospective cohort study included patients from two high-volume tertiary academic centers in the United States (January 2014–December 2024). We analyzed demographics, comorbidities, BMI, perioperative metrics, and surgical outcomes, including early and late complications, rehospitalizations, and reinterventions.

Results

A total of 1,039 patients underwent primary robotic Roux-en-Y gastric bypass with the mean age of 45.61 ± 12.20 years, and 83.6% female population. There were no conversions to open surgery. Early postoperative complications occurred in 132 (12.70%) patients, predominantly minor (Clavien–Dindo I–II). Major complications (Clavien–Dindo III –V) occurred in 34 (3.27%) patients, including one case of sepsis requiring ICU admission (0.1%) and one 30-day mortality (0.1%). There were no anastomotic leaks. Thirty-day readmission occurred in 91 (8.76%) patients, and early reintervention in 34 (3.27%) patients. Late complications occurred in 127 (12.22%) patients, most commonly small bowel obstruction, and 101 (9.72%) patients required readmission. Late reintervention occurred in 91 (8.76%) patients, resulting in a total of 104 reinterventions (10.01%). The estimated 10-year cumulative incidence was 9% for small bowel obstruction, 1% for gastrojejunal ulceration, and 13% for late reinterventions. Mean BMI decreased from 43.9 ± 8.5 kg/m² preoperatively to 33.97 ± 10.6 kg/m² at 6 months and 30.22 ± 8.7 kg/m² at 12 months, corresponding to total body weight loss of 20.96% and 22.84%, respectively.

Conclusion

Robotic-assisted gastric bypass is safe and effective, with complication rates similar to or even lower than laparoscopic RYGB. The extremely low leak rate (0.1%) suggests robotic assistance may further reduce serious complications, highlighting its growing role in metabolic and bariatric surgery (MBS).
