Laparoscopic adjustable gastric banding (LAGB) has been considered by many as the treatment of choice for morbid obesity because of its simplicity and encouraging early results. The aim of this prospective study was to critically assess the effects, complications, and outcome after LAGB in the long-term, based on a 12-year experience. Between June 1998 and June 2009, all patients with implantation of a LAGB have been enrolled in a prospective clinical trial. Results were recorded and classified, with special regard to long-term complications, re-operation rate, and graft survival. LAGB was performed in 167 patients (120 female, 47 male) with a mean age of 40.1 +/- 5.2 years. Operative mortality was 0%, overall 1.2% (not band-related). Overall patient follow-up was 94.0%. Mean excess weight loss (EWL) after 1, 2, 5, 8, and 10 years was 31.1 +/- 7.5% (p < 0.005), 44.2 +/- 6.5% (p < 0.001), 50.3 +/- 6.9% (p < 0.001), 51.7 +/- 6.3% (p < 0.001), and 48.8 +/- 6.0% (p < 0.001), respectively. The non-responder rate (EWL < 30%) after 2, 5, 8, and 10 years was 24.5%, 18.3%, 12.5%, and 16.6%, respectively. The early complication rate (<30 days) was 7.8% (13/167), with 10 minor and three major complications. Late complications (>30 days) occurred in 40.1% (67/167), of whom seven were minor and 60 were major complications (three band infections, two band migrations, 11 band leakages, two slippings/pouch dilatations, two band intolerances, and 40 esophageal dilatations). The overall re-operation rate was 20.4% (34/167). The graft survival of the implanted band after 2, 5, 8, 10, and 12 years was 98.8%, 94.0%, 86.8%, 85.0%, and 85.0%, respectively. The failure rate of the procedure after 2, 5, 8, and 10 years was 25.7%, 24.3%, 25.7%, and 31.6%, respectively. In the present long-term high-participation follow-up study, LAGB is a safe and effective surgical treatment for morbid obesity. However, the high complication, re-operation, and long-term failure rates lead to the conclusion that LAGB should be performed in selected cases only, until reliable criteria for patients at low risk for long-term complications are developed.
