Robotic Roux en Y gastric bypass can be safe and cost-effective in a rural setting: clinical outcomes from a community hospital bariatric program.

Robotic Roux en Y gastric bypass (R-RYGB) is becoming more common due to the shifting trend toward robotic gastrointestinal surgery. The goal of this study is to determine if R-RYGB can be safely implemented at a robotic bariatric surgery program in a community hospital with similar results to laparoscopic RYGB (L-RYGB) in a cost-effective manner. A total of 50 R-RYGB procedures were performed with the Xi and the X da Vinci systems and compared with 50 L-RYGB cases by a single surgeon from October 2018 to January 2020 at an acute-care community hospital in a rural setting with a high-volume MBSAQIP-accredited program. A retrospective chart review was conducted with IRB approval and statistical analysis of 30-day morbidity, mortality, re-interventions, and resolution of co-morbidities, with financial analysis of cost reduction. Both groups were similar in age, gender, ASA class, co-morbidities, and body mass index (BMI). There was no mortality or anastomotic leak. The 30-day morbidity for R-RYGB was 10.0% with a re-operation rate of 4.0%. There were no conversions to open, and the mean hospital length of stay was 2.22 ± 1.19 days. There were no statistically significant differences between R-RYGB and L-RYGB with respect to any measured outcome, including intraoperative time (121.94 vs. 113.52, respectively; p = 0.1495). However, when incidences and percentages were used, R-RYGB had improved performance for most of the outcomes measuring safety. There was an average cost reduction of $816.90 per case (total saving of $40,845.00 for 50 cases) in the R-RYGB by transitioning from a hybrid approach to a totally robotic approach. R-RYGB appears to be as safe as L-RYGB and can be performed in a rural community hospital while maintaining a low complication rate, achieving a high co-morbidity resolution rate, and saving costs with a totally robotic approach.
