title: Prospective evaluation and 7-year follow-up of Swedish adjustable gastric banding in adults with extreme obesity.
abstract: BACKGROUND
  Swedish adjustable gastric banding (SAGB) is a widespread laparoscopic procedure in bariatric surgery. Few long-term data is available.
  
  
  OBJECTIVE
  To determine long-term outcome after SAGB in 196 patients studied prospectively.
  
  
  METHODS
  196 patients, 40 men, and 156 women have been operated from 1996 to 2005. Age was 38 +/- 1 (mean +/- sem) years. Mean follow-up was 63 +/- 2 months.
  
  
  RESULTS
  Hospital morbidity was 3% (0.5% early reoperation); mortality was 0. Late complications were band migration (1%), leakage (5%), slipping (4%), or pouch dilatation (8%). Minor reoperations (tube replacement, port-related, and hernias) were needed in 7.5%. Cumulative major reoperation rate reached 32%. Eighteen percent had a band replacement; 14% had removal of band anatomy. Late mortality was 0.5%. Exactly 7 years after SAGB, BMI decreased from 45 +/- 1 kg/m2 to 33 +/- 1 kg/m2, and excess weight loss (EWL) was 61 +/- 4%. Sixty-eight percent of the patients reached > or = 50% EWL.
  
  
  CONCLUSIONS
  In 14% of the patients, the band anatomy had to be removed. Seven years of intact band anatomy leads to a successful EWL of 61 +/- 4% and to EWL of > or = 50% in 68%. However, cumulative major reoperation rate of 32% in 7 years makes it mandatory to offer and discuss other bariatric procedures to the respective patients.
