Introduction:
Bariatric surgery is associated with 20-30% weight recidivism. As a result, revisional bariatric operation is increasingly performed. Disparity in bariatric outcomes remains controversial and very little is known about revisional bariatric surgery outcomes in ethnic cohorts.
Methods:
Revisional bariatric cases were identified from the 2015 and 2016 Bariatric Surgery Accreditation and Quality Improvement Program Participant Use Data File. 1:1 case-control matching was performed and perioperative outcomes compared between racial cohorts.
Results:
24,197 cases were analyzed, including 20.78% Black patients. At baseline, there were differences in demographics and pre-existing conditions between racial cohorts. Matched analysis compared 7,286 Black and White patients. Operative duration (p = 0.008) and length of stay (p = 0.0003) were longer in Black patients. Readmission (6.8% vs. 5.4%, p = 0.009) was higher in Black patients. Bleeding (0.82% vs. 0.38%, p = 0.02) and surgical site infection (SSI) (2.6% vs. 1.8%, p = 0.01) were higher in White patients.
Conclusion:
Revisional bariatric surgery is safe. Apart from a higher rate of bleeding, SSI and readmission, outcomes were not mediated by race.
