Bariatric surgery has been established as the most effective long-term treatment for morbid obesity and obesity-related comorbidities. Despite this success, racial disparities exist that preclude Hispanic patients from being considered for bariatric surgery and the optimal operative approach in this ethnic group has yet to be defined.


We performed a retrospective review of obese patients treated at our institute between 2008 and 2013. We identified self-reported Hispanic patients who underwent a laparoscopic gastric bypass (LGBP), sleeve gastrectomy (LSG), or gastric banding (LGB). The primary end point for this study was excess weight loss (EWL) at 6, 12, and 24 months. Secondary end points included improvement of obesity-related metabolic parameters at 1 year.


We identified 416 Hispanic patients who underwent bariatric surgery (233 LGBP, 114 LSG, 69 LGB) at our institute from 2008-2013. Follow-up at 6, 12, and 24 months was 57.7%, 54.3%, and 45.2%, respectively. Mean preoperative BMI for all patients was 47.1+14.2 kg/m². EWL was significantly more pronounced for patients in the LGBP group than in the LSG or LGB group (Figure). Obesity-related metabolic parameters decreased in all 3 surgical groups (Table) and were not significantly different.


LGBP seems to yield more effective EWL than LSG and LGB among Hispanic patients. At 1 year, obesity-related metabolic parameters had comparable improvement irrespective of the bariatric procedure performed.
