title: [Comparative results between vertical ringed gastroplasty and duodenal switch in morbid obesity].
abstract: BACKGROUND
  The only effective long-term treatment for morbid obesity is bariatric surgery. AIM. To compare the long-term results of vertical banded gastroplasty (VBG) and duodenal switch (DS). Quality of life, weight loss and reoperations were evaluated.
  
  
  METHODS
  A retrospective study of 85 patients with VBG and 49 with DS with a follow-up of more than 5 years was performed. The mean preoperative body mass index (BMI) was 48.8 kg/m2 in VBG patients and 50.33 kg/m2 in DS patients.
  
  
  RESULTS
  At 5 years, 87.5% of patients with DS had maintained a percentage of excess weight lost (%EWL) of more than 50%, and were therefore counted as successes, compared with 55% of those with VBG (p < 0.0001). Eight VBG patients (9.4%) and one DS patient (2.04%) required re-operations due to failure of the technique. None of the VBG patients with a %EWL of more than 50% could eat a normal diet, whereas more than 80% of patients with DS had no dietary restrictions.
  
  
  CONCLUSIONS
  At 60 months follow up, only the DS patients fulfilled the requirements of the American Society of Bariatric Surgery of %EWL superior to 50% in more than 75% of the patients.
