Background. Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) have comparable weight loss outcomes in a general bariatric population. Objectives. is study aimed to investigate whether similar outcomes can be observed in Hispanic and African American population. Settings. Community Hospital in New York, New York, United States. Methods. e 5-year prospective data of patients who underwent LRYGB and LSG at a single center were retrospectively reviewed. e long-term weight loss outcomes between patients who had LRYGB and LSG were compared after adjusting for age, sex, race, diabetes mellitus, and hypertension with the linear mixed-effects or logistic regression model. Results. Most patients were Hispanic (59.2%) and African American (22.7%). e mean% total weight loss (%TWL) values of patients with BMI <45kg/m 2 who underwent LRYGB and LSG were 73% and 62% after 1 year, 69% and 56% after 2 years, and 71% and 54% after 5 years, re- spectively. In patients with a BMI of 45–50 kg/m 2 who underwent LRYGB and LSG, the mean %TWL values were 69% and 56% after 1 year, 75% and 58% after 2 years, and 57% and 45% after 5 years, respectively. Meanwhile, the %TWL values of patients with BMI >50kg/m 2 who had LRYGB and LSG were 53% and 42% after 1 year, 53% and 45% after 2 years, and 49% and 36% after 5 years, respectively. All results were statistically significant (p < 0.0001) and remained valid after adjusting for cofactors. Con- clusion. us, LRYGB had consistent and sustained long-term weight loss outcomes compared with LSG in a predominantly ethnically diverse patient population with different BMI. Our study had several limitations in that it is retrospective in nature and some patients were lost to follow-up during the study period. 1.Introduction e prevalence of obesity and its related diseases is in- creasing in the US and other countries worldwide. Obesity in adults is defined as a body mass index (BMI) greater ≥30 kg/m 2. According to the Centers for Disease Control and Prevention, the prevalence rate of obesity is 39.8%, and 93.3 million adults present with such con- dition in the US [1]. e annual cost for the medical management of obesity in the US was approximately $147 billionin2008.In2016,1.9billionadultswereoverweight and 650 million had obesity worldwide [2]. e preva- lence of such condition worldwide has tripled from 1975 to 2016 and is higher in African Americans and Hispanic Hindawi Minimally Invasive Surgery Volume 2021, Article ID 9702976, 6 pages https://doi.org/10.1155/2021/9702976
