Laparoscopic adjustable gastric banding: initial Tasmanian experience

Abstract

Background: The laparoscopic adjustable gastric band (LAGB) is a minimally invasive, adjustable and reversible bariatric procedure. The present paper reports an initial 2 year experience at Royal Hobart Hospital, Tasmania.

Methods: Between February 1999 and June 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%).

Results: The average weight loss was 12.4 kg at 3 months, 25.3 kg at 1 year and 34.8 kg 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. Reoperation for band slippage occurred in 24 patients (11%), and the injection reservoir required changes in 22 patients (11%). There were three perforations while inserting the LAGB, two non-fatal pulmonary emboli (1%) and two cases of deep vein thrombosis (1%). There has been no mortality.

Conclusions: Laparoscopic adjustable gastric banding is a safe and effective method of achieving significant (P < 0.0001) weight reduction in the morbidly obese.
