Background:
Laparoscopic adjustable gastric banding (LAGB) has been our operation of choice for morbid obesity since 2003. The aim of this study was to review 5 years of LAGB procedures at a single institution in China.
Methods:
All patients who underwent LAGB at our institution from June 2003 to November 2009 were analyzed retrospectively. A telephone survey of patients was conducted in 2010.
Results:
This study included 188 Chinese patients, of which 69.7 % were female and 8 (4.3 %) were super-obese (body mass index (BMI) >50 kg/m(2)). The mean age of patients was 27.2 ± 9.1 years (range, 14-55 years), mean weight was 106.8 ± 24.7 kg (range, 67-230 kg), and mean BMI was 37.5 ± 6.2 kg/m(2) (range, 26.1-61.7 kg/m(2)). The mortality rate was 0 %. Six bands were removed (four for slippage). One operation was converted to an open procedure. Ninety-eight patients were surveyed by telephone. The mean weight loss was 17.6 ± 12.5 kg, and the mean follow-up time was 23.6 months. Percentage excess weight loss (%EWL) at 3 months, 6 months, 1 year, and 2 years was 27.8 ± 16.4, 39.0 ± 23.1, 44.1 ± 27.3, and 43.1 ± 28.4 %, respectively. The nonresponder rate (%EWL <30 %) at 2 years was 33.3 % (20/60). Weight regain of more than 10 kg from nadir was observed in 10 of the 98 patients (10.2 %).
Conclusions:
LAGB is a relatively safe procedure with few major complications. However, a minority of morbidly obese patients did not benefit sufficiently from their surgery.
