Outcomes and Trends of Endoscopic Bariatric Therapies (EBT) Among Minority Populations.

Abstract

Endoscopic bariatric therapies (EBT) have emerged as effective options for weight loss. While the benefits of EBT have been documented, data regarding such therapies among minority populations remains scant. We aim to investigate EBT trends and outcomes in minority populations. Data were extracted from the 2015 to 2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) databases. Intragastric balloon (IGB) and endoscopic sleeve gastroplasty (ESG) cases were identified, and procedure volume assessed by year and race/ethnicity. Measures of interest included year-to-year mortality, surgical complications, and 30-day adverse outcomes. Of 966,646 cases in the MBSAQIP databases, 5209 (0.54%) IGB and ESG cases were included. 10.7% were black, and 81.6% were female patients. Compared to white patients, black and Hispanic patients were younger (p < 0.01) with a higher body mass index (p < 0.001). Mortality (0.03% vs. 0% vs. 0%, p = 0.99), reoperation (1.1% vs. 0.8% vs. 0.6%, p = 0.30), and reintervention (3.9% vs. 3.2% vs. 2.3%, p = 0.09) rates were similar between racial/ethnic cohorts. All complications were similar between racial/ethnic cohorts, except a higher rate of venous thromboembolism, in Hispanic (1.04%, p < 0.01) compared to black (0.18%) and white (0.21%) patients. IGB and ESG were predominantly performed in white and Hispanic patients, respectively. ESG was associated with a higher leak (0.6% vs. 0.02%, p < 0.01) and venous thromboembolism (VTE) (1.0% vs. 0.12%, p < 0.01) rate. While EBTs have increased annually, they are performed less in black patients. Future studies are needed to identify access barriers for black patients. They are safely performed with similar outcomes in racial/ethnic cohorts, except for a higher VTE rate in Hispanic patients.
