The Laparoscopic Sleeve Gastrectomy (LSG) has been performed in Australia for around 8 years now, and involves up to 85% of the stomach being permanently removed via a stapling device, leaving the remaining stomach to form a tube. Due to the restriction in size, the stomach now holds much less food than previously, resulting in significant weight loss.
This procedure is not reversible, and combined with the BMI comprehensive and high-intensity aftercare programme, patients can achieve optimal health and weight loss results.
Patients experience faster weight loss than with other surgical options like a Gastric Band, with an expected weight loss of around 60% excess weight loss (EWL) at 12 months, which is approximately 40-60kg (depending on the patients starting weight).
As with any weight loss procedure, a key component is the aftercare programme; at BMI, we offer a 24-month high-intensity programme, based on our experience, to ensure patients are well-educated to keep the weight off. The procedure is performed laparoscopically (keyhole), and patients stay in hospital for 2-3 nights post-procedure.
The gastric sleeve is considered a permanent procedure, due to the permanent removal of a portion of the stomach, and has a lower complication risk than other surgical procedures such as the gastric bypass. Unlike the gastric bypass, with the sleeve gastrectomy there are no malabsorption or nutritional issues.
The LSG works in multiple ways, one being the restrictive element to the procedure; patients are only able to eat a small meal (e.g. 1/2 a cup) before the stomach is full.The stomach will then send signals to the brain that tell the brain to feel full. It is important patients chew your food slowly and take time between mouthfuls, as this this allows for these signals to reach the brain so patients no longer feel hungry. The second way the LSG works is the hormonal; when the procedure is performed, part of the stomach that is removed is the part that normally produces ghrelin, a hormone that induces hunger. The combination of these two mechanisms allows patients to lower their caloric intake, resulting in weight loss.
Quick facts about Gastric Sleeve
- Laparoscopic/keyhole surgery – takes around 45-60mins
- Considered permanent due to the removal of up to 85% of the stomach
- Rapid weight loss; most of the weight loss is experienced in the first 12 months
- Average weight loss of around 60% excess weight
- Lower complication risk than other surgical options like Gastric Bypass
- Hospital stay of 2-3 nights
- Minimal complication rate compared to other surgical procedures
- Risks can involve bleeding, re-operation, stricture or narrowing of the sleeve, and reflux, among others.
The Gastric Sleeve is performed by Dr David Links at BMI as part of our 24-month programme, including access to our proprietary patient management programme, BMI Active.
