title: An adjustable vertical banded gastroplasty does not eliminate the risk of staple-line disruption.
abstract: BACKGROUND
  The two main reasons for reoperation after vertical banded gastroplasty (VBG) in the treatment of obesity are staple-line disruption and stomal stenosis.
  
  
  METHODS
  Seven morbidly obese patients of mean (+/-SEM) body mass index (BMI) 43.7 +/- 1.9 kg/m2 treated with an adjustable vertical banded gastroplasty (AVBG).
  
  
  RESULTS
  No complications of the band system were reported. Weight-loss [BMI at 2 years follow-up 33.9 +/- 6.9 kg/m2 (n = 5)] was equivalent to that seen after VBG with a fixed band. Two of the patients developed staple-line disruption at 18 and 24 months after surgery.
  
  
  CONCLUSIONS
  AVBG allows adjustment of the stoma, but staple-line disruption was common in this small series. It is possible that an excessive filling of the band in order to achieve excess weight loss results in a high pressure in the upper pouch which increases the risk of staple-line disruption.
