title: Leakage of adjustable gastric bands.
abstract: BACKGROUND
  Surgery for morbid obesity has increased since the introduction of the adjustable gastric bands. Their advantage is the adjustability of the band, which can be inflated or deflated percutaneously according to weight loss without altering the anatomy of the stomach. We present 5 cases of leakage of the Swedish adjustable gastric band (SAGB) as a result of tearing of the balloon.
  
  
  METHODS
  In our series, 29 patients received an SAGB; the remaining 20 received the LapBand. All but 4 procedures were performed laparoscopically. The adjustable gastric band (AGB) was inflated according to passage seen on gastro-esophagogram. According to weight loss or complaints of passage, the gastroesophagogram was repeated, and the AGB was inflated or deflated.
  
  
  RESULTS
  No major complications were observed postoperatively. All but 5 patients showed weight loss and restriction of food intake after filling of the AGB. These 5 patients had all received an SAGB. High-pressure filling with contrast medium showed leakage of the SAGB. After removal the SAGB, 4 showed a tear at the site of fixation of the balloon to the band, and 1 showed a puncture of the balloon. The tears most probably occurred as a result of inadequate fixation while the SAGB was positioned around the stomach.
  
  
  CONCLUSIONS
  To our knowledge, this complication has not been described before. The manufacturer of the SAGB has been notified, and consequently the fixation site has been reinforced.
