Abstract

Background: Race may affect outcomes after bariatric surgery. This study compares outcomes in terms of weight loss and comorbidity resolution between African-Americans and whites after laparoscopic adjustable gastric banding (LAGB).

Methods: Data from 959 patients undergoing LAGB between July 2001 and July 2004 were prospectively collected and entered into an electronic registry. Propensity score matching analysis was used to match whites to African-Americans on the basis of age, gender, and preoperative body mass index (BMI). Preoperative comorbidities (diabetes, hypertension, obstructive sleep apnea, hypercholesterolemia, and hypertriglyceridemia) were also compared. Operative time (OR), length of stay (LOS), comorbidity resolution, and percent excess weight loss (%EWL) at 1, 2, and 3 years were analyzed. All data were updated through May 2006.

Results: A total of 65 white LAGB patients were matched to 58 African-American LAGB patients on the basis of age, gender, and preoperative BMI. The preoperative mean age and BMI were 37 +/- 19 years and 47 +/- 7 kg/m2, respectively. A total of 55% of the white group and 64% of the African-American group had one or more comorbidities (P = NS). Median OR time and LOS were similar in both groups: 50 minutes and 23 hours, respectively. The majority of patients in both groups had major improvement or resolution of one or more comorbidities (61% whites vs 77% African-Americans, P = NS). There was, however, a significant difference in %EWL between whites and African-Americans at each time interval (49% vs 39% at 1 year; 55% vs 44% at 2 years; 52% vs 41% at 3 years; P < .05 for all values.).

Conclusion: Despite the disparity in weight loss with the LAGB in African-Americans and whites, both patient populations experienced a similar improvement/resolution of obesity-related comorbidities.
