title: Five-year weight loss experience of outpatients receiving laparoscopic adjustable gastric band surgery.
abstract: BACKGROUND
  This study evaluated the efficacy and safety of laparoscopic adjustable gastric banding (LAGB) in a large cohort of morbidly obese patients followed for up to 5 years.
  
  
  METHODS
  Morbidly obese patients, ≥ 16 years of age, who underwent LAGB surgery at the Surgical Weight Loss Clinic in Ontario, Canada, between May 2005 and January 2011 were eligible for this retrospective chart review. Electronic files were searched to identify all patients who met the inclusion/exclusion criteria. Demographics, weights at baseline and follow-up visits (up to 60 months following surgery), and post-operative complications were documented. As follow-up visits occurred at unevenly spaced intervals within and across patients, modeling methods were used to more accurately assess mean % weight loss (WL) and % excess weight loss (EWL) over time.
  
  
  RESULTS
  This study included 2,815 patients (82 % female, mean age 43 years, mean baseline BMI 44.6 kg/m(2)) followed for a mean of 21.8 ± 15.4 months. Complications developed in 238 patients (8.5 %), the most frequent being prolapse/slippage (4.2 %), tubing/access port problems (1.2 %), and explantation (1.2 %). Mean %WL and %EWL progressed continuously over the first 2.5 years post-LAGB, plateauing at 20 and 49 %, respectively, for up to 5 years of follow up. Factors associated with increased weight loss were time since surgery, greater baseline weight (excess weight), older age at time of surgery, and male gender.
  
  
  CONCLUSIONS
  Weight loss was maintained for up to 5 years in our population of patients who underwent LAGB for the treatment of morbid obesity.
