There are three main types of bariatric procedures conducted in Australia. These are as follows:
- Laporoscopic Adjustable Gastric Banding (The LAP BAND system).
- Gastric Bypass.
- Non-Adjustable gastric bypass (Sleeve Gastrectomy).
Of the three major forms of bariatric procedures executed in Australia, the LAP-BAND system is the most commonly used (recent research gathered that 95% of patients have chosen to use this type of surgery).
Studies also verify that a gastric banding can lose just over 60% of their surplus weight within the first year.
LAP BAND Procedure
The LAP BAND procedure is a straightforward 20-minute procedure performed by an accomplished surgeon in a day surgery clinic where an adjustable ‘restrictive band’ is positioned around the peak of the stomach. The adjustable gastric band works by condensing the amount of food that can be eaten in a sitting and by aiding you to feel ‘full’ more speedily. Ultimately, you feel more fulfilled more immediately and the urge to overeat is taken away.
- The LAP BANDS system is adjustable and reversible.
- The surgery is performed through small incisions and with long shafted instruments.
- There are no major cuts to the abdomen.
- The gastric band, like a belt, is fastened around the top of the stomach.
- Unlike other bariatric surgery, the stomach and intestines re not cut or re routed.
- The band presses on the stomach creating sensations of fullness. The band can be adjusted to increase or decrease hunger sensations.
- Only small amounts of food can be eaten at once because of the tiny pouch above the band.
- Even though weight loss surgery patients often have many other serious illnesses, the comparable risk is about the same as for a laparoscip cholecystectomy (gallbladder removal).
- Wound complications
- Clots in leg veins
- Erosion of the band (breaking down of the band)
- Prolapse (where the band slips down)
- Port infection (skin infection where the tubing exits the body)
- Device failure (such as a tubing fracture)
With this procedure a tiny stomach pouch is fashioned. A Y shaped part of the small intestine is then connected to the pouch to permit food to bypass the lower stomach, the first segment of the small intestine, and the second segment of the small intestine. This bypass decreases the absorption of nutrients and so reduces the calorie intake leading to weight loss.

The sleeve gastrectomy procedure requires utilizing staples to produce a lengthy tubular sleeve of stomach beside the lesser arc side of the stomach, together with the majority of the fundus and the body of the stomach, being detached permanently.
The new, lengthy and slim ‘sleeve’ of a stomach is smaller than the original stomach, limiting the quantity of food that it is able to hold, and so supporting weight loss. The key outcome of the procedure is to take out the piece of the stomach that produces ghrelin (a hormone that plays a chief function in determining how hungry we are). As weight decreases the stomach starts to generate an amplified amount of ghrelin that informs the brain to amplify appetite. Patients who have had a sleeve gastrectomy usually have a significantly condensed appetite and as they lose weight do not experience the hunger pains that other dieters tend to do.
The benefit of sleeve gastrectomy over the other restrictive operations is that with the sleeve gastrectomy the whole gastric tube fills when eating so patients feel full rather than obstructed. As the sleeve gastrectomy does not have a band, there are not many food intolerances in the long term.
