Background: Laparoscopic adjustable gastric banding (LAGB) is now the most common surgical treatment for obesity. However, few data exist on the outcome of LAGB in our setting.

Objective: This study aimed to assess the outcome of obese adults after LAGB in terms of weight loss.

Methods: We conducted a retrospective review of records of all patients who underwent LAGB between January 2004 and December 2009 at St Luke’s Medical Center. Patients were included in the analysis if they were at least 18 years old at the time of surgery and had one or more recorded weight measured during the follow-up period. Outcome was assessed using percentage excess weight loss (%EWL) at 1 year ±6 months intervals. Analysis of variance was used to compare three or more groups of continuous variables while chi-square or Fischer’s exact were used to analyse categorical variables. Logistic regression was done to determine independent factors that predict successful weight loss after gastric banding.

Results: A total of 97 patients met the inclusion criteria. The majority of the patients were Filipino (77%), and female (61%). Their ages ranged from 18 to 68 (mean 36.1 years ±12.2). The mean BMI was 44.1±0.1 kg/m2 and mean excess weight was 61.4±26.5 kg. Greatest %EWL (43.46%) and BMI reduction (21.55%) were attained at 2 years but was not sustained thereafter. The highest success rate (%EWL >50%) was also achieved at 2 years (48%). Follow up rate was high at 6 months (98%) and 1 year (68%), but, thereafter fell below the accepted value of 61%. Independent predictor of successful LAGB at 1 year was BMI <43.4 kg/m2.

Conclusion: Obese adults achieved a substantial mean weight loss of 43.46% at 2 years after LAGB.
