What is Lap Band Surgery?
A Gastric Band, commonly referred to as a lap-band, is a silicon-based adjustable device, surgically placed around the upper stomach and sutured in place. It is rarely performed in Australia.
This effectively shrinks the overall volume of the stomach, from 500ml to 50 to 80ml, and restricts solid food from entering the stomach for several hours, causing the sensation of ‘feeling full’ to occur after smaller portions and for longer time frames.
Advantages
- Safe, with low immediate complication risk
- Reversible, as anatomy is not altered
- Doesn’t involve dividing or removing any part of your stomach or intestine
- 40% excess weight loss
- Fast recovery and minimal scarring
Disadvantages
- Lifetime monitoring, with 40% to 50% need for
revisional surgery - Risk of 1 in 300 of stomach or oesophagus damage causing leak
- Reduces quality of eating
- Mechanical problems, slippage or erosion over time
- Access port flipping or infection
- Oesophageal dilatation
How it’s performed?
Lap band surgery is a straightforward procedure that typically lasts about an hour and is performed under general anaesthesia. To access the stomach, four to five small incisions, each measuring 1 to 2 cm, are made to facilitate the passage of instruments. The lap band itself consists of a small piece of tubing connected to a band, which can be adjusted for tightness. This band is connected to a reservoir implanted beneath the skin, below the ribs on the left side.
Five weeks after the surgery, patients undergo their first “fill” procedure. This involves injecting a small amount of saline into the reservoir, causing the band to tighten around the stomach. This restriction leads to a sensation of fullness and prompts the commencement of weight loss.
