Five Year Trends in the Utilization of Robotic Bariatric Surgery Procedures, United States 2015–2019

Purpose Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes. Methods Retrospective analysis of 2015–2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher’s exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes. Results The use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 ( N = 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26–38 min). Conclusion Robotic MBS shows higher intervention and readmission even after controlling for cofounding variables. Graphical Abstract
