Our Procedures

The Surgery: 

The sleeve gastrectomy, also called a vertical sleeve gastrectomy or gastric sleeve, is a procedure where about 80% of the stomach is removed, leaving a sleeve-shaped stomach. The procedure is typically performed laparoscopically, through a number of small incisions on the abdomen, under a general anaesthetic. The surgery takes around 1 to 1.5 hours. 

How does it cause weight loss? 

The sleeve gastrectomy is a restrictive procedure. By restricting the size of your stomach, the amount you can eat is limited. Additionally, the hunger-producing hormone, Ghrelin, is mainly created in the stomach. After surgery, the Ghrelin drops significantly, which reduces your food craving. 

How much weight can I expect to lose? 

Studies have found that at one year after surgery, patients have lost 68% of their excess weight. At five years after surgery, patients have lost 53.2% of their excess weight. These amounts are averages, and the amount of weight loss varies from individual to individual.

How long do I need to stay in hospital? 

Typically 1 to 2 nights. You may require longer if you have a complex health history. 

Is the procedure safe? 

The sleeve gastrectomy has a low complication rate, however every surgery has risks. 

Short term risks can include: 

  • Excessive bleeding
  • Infection
  • Blood clots 
  • Stomach leaks

Long term risks can include: 

  • Reflux
  • Malnutrition
  • Hernia 
  • Vomiting 

Though it may seem daunting, the benefits of the surgery often outweigh the risks. Both risks and benefits should be assessed when considering surgery.

How much does the surgery cost?

The Minimiser Ring – Banded Sleeve Gastrectomy
The sleeve gastrectomy is a restrictive weight loss operation, which means the main factor to lose weight is maintaining small portion sizes. Unfortunately, the stomach has the ability to stretch, even after a sleeve gastrectomy, which can happen over time, and lead to increased portion sizes and weight gain. To prevent this from happening, a device called a Minimiser Ring can be placed in the upper part of the sleeve during surgery. It has been shown that this gives better weight loss in the long term, can have a better effect on Type II Diabetes and doesn’t contribute to reflux or heartburn. Sometimes, people with a banded sleeve can experience food getting stuck in their esophagus, especially if they have eaten quickly or larger portion sizes, so it works as a constant reminder to be mindful of your eating habits. If you are interested in a banded sleeve, we are more than happy to discuss this with you.
