Abstract
Objective. To determine the effect of laparoscopic adjustable gastric banding (LAGB) on weight loss and the association between initial body mass index (BMI) and successful weight loss, defined as >50% excess weight loss (EWL) among obese Filipino adults at St. Luke’s Medical Center. Methodology. Data from 97 patients who were at least 18 years old at the time of gastric banding were reviewed retrospectively. Patient follow-up was poor 2 years post-surgery, which precluded analysis of follow-up data beyond 2 years. Changes in weight loss parameters from baseline to the different observation periods were carried out using paired t- test. To determine the association of different factors with success in weight loss, Independent t-test and Chi-square tests were used. A p-value ≤0.05 was considered significant. Results. Majority of the patients were female (61%) and Southeast Asian (77%). Ages ranged from 18 to 68 years. Mean BMI was 44.1 ± 0.1 kg/m 2 and mean excess weight was 61.4 ± 26.5 kg. Excess weight loss of 43.84 ± 25.09% and BMI reduction of 21.54 ± 13.39% were attained at 2 years. Lower initial BMI with a mean of 38.12±3.28 kg/m 2 was associated with successful weight loss, 1 year after gastric banding (p<0.001). Conclusion. Patients attained 43.84% EWL 2 years after gastric banding. Those with higher initial BMI were less likely to achieve successful weight loss 1 year after gastric banding.
