    Abstract:
    BACKGROUND: For over a decade, the laparoscopic adjustable gastric band (LAGB) was 1 of the most performed bariatric procedures in Europe. This study is a retrospective analysis with prospectively collected data of the experience in 1 specialized Dutch center with the adjustable gastric band over 14 years. METHODS: Between 1995 and 2003, 201 patients underwent an LAGB for morbid obesity in our hospital. Data on preoperative clinical characteristic, postoperative outcome and weight loss patterns, and co-morbidities for up to 18 years are presented and evaluated using the Bariatric Analysis and Reporting Outcome System (BAROS). RESULTS: Average follow-up was 13.6 (± 2.0) years (163 mo) and 99% of patients with complete follow-up. Two thirds of patients reached an excess weight loss (EWL)>50% at some point after LAGB placement. However, due to insufficient weight loss or complications in 53% of patients, the LAGB had to be removed or converted to a Roux-en-Y gastric bypass. Additionally, half of the remaining patients had disappointing results according to the BAROS score. In total, less than one quarter (22%) of patients had a functioning band with a good result after the follow-up period. Although initially the number of patients experiencing co-morbidities was reduced, most of them returned and a large number of patients developed new co-morbidities. Complications, other than weight regain, were numerous as 47% of patients experienced at least 1. In total, 204 reoperations were performed in 137 (68%) patients. Furthermore, patients who were lost to follow-up did almost twice as bad in terms of EWL compared to patients who had regular follow-up. CONCLUSION: Morbid obesity is a chronic disease that can be resolved with bariatric surgery. One of the treatment options is the LAGB, which in the short term shows good results in terms of EWL and co-morbidity reduction. In the long term, however, EWL and co-morbidity reduction are disappointing, and the LAGB does not seem to live up to expectations. Besides the decrease in EWL over time, the number of reoperations required is alarming. In total, less than a quarter of patients still had a functioning band after a mean 14 years of follow-up.
