title: Patients' experience and outcomes after laparoscopic adjustable gastric banding in Washington state.
abstract: BACKGROUND
  There is very little evidence regarding the real world experience and outcomes after laparoscopic adjustable gastric banding (LAGB). Our objective was to estimate the amount of postoperative weight loss, change in co-morbidity status, and complications after LAGB. The setting was LAGB surgical centers in Washington state.
  
  
  METHODS
  A cross-sectional survey was developed to collect primary data from patients who had undergone LAGB in Washington state from 2004 to 2010. The survey contained questions on patient characteristics, weight change, co-morbidities, and complications after LAGB surgery. We used descriptive and other statistical tests to evaluate our key research questions by the period since LAGB.
  
  
  RESULTS
  A total of 1556 surveys were sent out, and 790 were returned (response rate 50.8%). Responders were categorized into 4 groups according to the follow-up period: <2, 2-3, 3-4, and >4 years. The corresponding average body mass index reduction in each group was 21.0%, 22.5%, 21.3%, and 20.4%. Of the respondents, 21.7%, 34.8%, 44.6%, and 38.7% indicated they did not have any adjustments in the year preceding the survey. The percentage of respondents who had undergone additional operations related to LAGB was 8.6%. Specifically, 3.6% of the respondents had undergone either band removal or conversion to another type of bariatric operation.
  
  
  CONCLUSIONS
  We found that although LAGB appeared to be beneficial for weight reduction and improving co-morbidities, the underuse of band adjustments and significant rate of treatment failure might limit the long-term effectiveness of LAGB.
