Methods
Between 1999 and 2001, 207 patients underwent LAGB insertion (176 female,
31 male). The mean age was 43 years (range: 16-74 years). Mean preoperative
weight was 125 kg (range: 83-210 kg) and mean body mass index (BMI) was
45.9 (range: 32.6-67.0). The Bioenterics LAGB (Inamed, Chullora, NSW,
Australia) was used in all cases. The average follow up was 17 months
(range: 3-24 months). Three patients were lost to follow up (1.5 percent).

Study Results
The average weight loss was 12.4 kg at 3 months, 25.3 kg weight
loss at 1 year and 34.8 kg weight loss at 2 years. The average BMI
was reduced from 45.9 preoperatively to 41.3 at 3 months, 36.9 at
1 year and 33.5 at 2 years. Re-operation for band slippage occurred
in 24 patients (11 percent), and the injection reservoir required
changes in 22 patients (11 percent). There were three perforations
while inserting the LAGB, two non-fatal pulmonary emboli (1 percent)
and two cases of deep vein thrombosis (1 percent). There has been
no mortality.
