title: [Medicoeconomic evaluation of the treatment of morbid obesity by Swedish adjustable gastric banding (SAGB)].
abstract: BACKGROUND
  Aim of the present study was to analyze the medicoeconomic impact of each treatment for obesity in France, taking into account morbid obesity-associated comorbidities from a health insurance perspective and to calculate the cost-effectiveness ratio of SAGB compared to the non-surgical treatment for various kinds of patients, as well as the budget impact on a given cohort of patients.
  
  
  METHODS
  The model studied surgery-eligible patients and compared the effectiveness of the SAGB treatment to the conventional treatment. The follow-up extended from 1 to 5 years. Costs analyzed were treatment-related direct medical costs, as well as potential comorbidities costs. The effectiveness is determined according to the BMI loss and its maintenance over time, together with the level of improved quality of life.
  
  
  RESULTS
  An evaluation on a series of 1,000 patients shows that the treatment with SAGB is dominant (less expensive, more effective in terms of loss of BMI and its duration) compared to the conventional treatment for patients suffering from type II diabetes or obstructive sleep apnea. The same evaluation in terms of QALYs shows that the treatment with SAGB is dominant compared to the conventional treatment for patients with a BMI >or= 35 kg/m(2) and a type II diabetes, as well as for patients whose BMI >or= 40 kg/m(2) (with or without type II diabetes mellitus).
