Robotic-assisted metabolic and bariatric surgery (MBS) is being performed with increased frequency in the United States, including for revisional MBS. However, little is known about perioperative outcomes between racial and ethnic cohorts after revisional robotic-assisted MBS. The goal of our study was to determine if there are racial differences in outcomes after robotic-assisted revisional MBS. University Hospital, United States. Using the 2015–2017 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, we identified patients undergoing revisional MBS by a robotic-assisted approach. Univariate analyses were performed of unmatched and matched racial and ethnic cohorts, comparing black versus white patients and Hispanic versus white patients. Of 2027 robotic-assisted revisional MBS cases in the database, 1922 were included in our analysis, including 67%, 22.6%, and 10.4% white, black, and Hispanic patients, respectively. At baseline, there were some differences in patient characteristics between racial and ethnic cohorts. After propensity matching, outcomes between black and white patients were similar, except for higher rates of superficial surgical site infection among white patients (P = .05) and higher rates of organ space surgical site infection in black patients (P = .05). Outcomes were also similar between matched white and Hispanic patients, except for a higher bleeding in white patients (2% versus 0%, P = .04). There were no mortality or morbidity differences between racial and ethnic cohorts. Morbidity and mortality after robotic-assisted revisional MBS do not seem to be mediated by race or ethnicity.
