Procedure Information
Gastric Band (Lap Band Surgery)Average of 58% excess weight in one year; 64.8% excess weight at two years; 47.1% excess weight loss maintained at 15 years▼
The LAP-BAND® System is placed around the top of the stomach during a 30-45 minute laparoscopic procedure, applying constant gentle pressure to increase a feeling of satiety on a smaller amount of food. It is completely reversible and adjustable via an access port beneath the skin.
Gastric Sleeve (Sleeve Gastrectomy)60 to 80% of excess weight loss over 2 years; 50 to 80% of excess body weight in the first six months to one year▼
The Sleeve Gastrectomy is a restrictive weight loss surgery that removes approximately 80% of the stomach, reducing it from 2 litres to 100-150mls. It is the most common weight loss surgery performed in Australia and is the procedure of choice for volume eaters and those with a history of eating disorders. The removed portion includes the fundus which produces the hunger hormone Ghrelin.
Roux-En-Y Gastric BypassAround 80% of excess weight in the first year; reduced to approximately 50 to 60% excess weight loss at 10 years▼
The Gastric Bypass takes advantage of both restriction and malabsorption. It involves formation of a small 20-30cc gastric pouch using stapling devices and rerouting of the small intestine. It is one of the most effective weight loss procedures and is generally reserved in Australia for patients who have failed sleeve surgery or are super obese.
Gastric Balloon (ORBERA® System)Average of 10-15kg or 10% of initial weight at 6 months; 3.1x the weight lost compared to diet and exercise alone▼
The intra-gastric balloon is a temporary, non-surgical weight loss procedure where an inflatable balloon is placed in the stomach under sedation and filled with saline up to 400-700mls. It must be removed after six months and can be replaced. It is used to kick-start weight loss or as a bridge to definitive surgery in severely morbidly obese patients.
Weight Loss Revision Surgery▼
Revision surgery addresses complications or weight regain following previous weight loss operations. Between 10 to 30 percent of patients having any type of weight loss surgery will need later surgery. Options include fixing complications, repairing operations no longer working, or converting from one procedure to another (band/sleeve/bypass).
