Abstract

BACKGROUND: The rate of robotic-assisted metabolic and bariatric surgery (MBS) is increasing. While discord remains about racial disparity in primary MBS, there are no data on robotic MBS outcomes in racial cohorts.

OBJECTIVES: To determine whether outcomes following robotic-assisted Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are mediated by race or ethnicity.

SETTING: University Hospital, United States.

METHODS: Robotic RYGB and SG cases were identified from the 2015-2017 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) databases using Current Procedure Terminology codes 43644, 43645, and 43775. Selected cases were stratified by race and ethnicity. Case-control matched and logistic regression analyses were performed.

RESULTS: Matched analyses compared outcomes in 2666 RYGB cases of Black versus White patients and 1794 RYGB cases of Hispanic versus White patients. Black RYGB patients had longer operative lengths (OLs; P = .0008) and postoperative lengths of stay (P = .001), and a higher rate of pulmonary embolism (P = .05). Hispanic (versus White) RYGB patients had longer lengths of stay (P = .007). All other outcomes were similar between RYGB racial and ethnic cohorts. Matched analyses also compared outcomes of 8328 SG cases in Black versus White patients and 4852 SG cases in Hispanic versus White patients. Black patients had longer OLs (P = .004), had longer lengths of stay (P < .0001), had higher overall morbidity (P = .02), had higher bariatric-related morbidity (P = .02), had higher rates of readmission (P = .009), and were more likely to have an operative drain present at 30 days (P = .001). All other outcome measures were similar between racial/ethnic SG cohorts.

CONCLUSION: Robotic-assisted SG is associated with higher overall and bariatric-related morbidity, but not mortality. However, robotic-assisted RYGB and SG remain safe, with lower rates of mortality and morbidity.
