At Blackrock WeightCare we perform our sleeve gastrectomy operations either by laparoscopic (keyhole) surgery or using the da Vinci Xi robotic surgical system.

A sleeve gastrectomy reduces the size of the stomach considerably. A stomach ‘sleeve’ is created using a surgical stapler and a tubular sizing device and then the outer area of the stomach is removed.

It’s important to get the stomach sleeve the correct size. This is because if the volume of the stomach is too big, you won’t lose enough weight and if it’s too small, you could develop complications such as tightness or a kink.

Quick guide

How does a sleeve gastrectomy work?

Sleeve gastrectomy surgery reduces the size of your stomach. As your stomach is smaller, you’ll eat reduced portion sizes because you’ll feel full more quickly, and you’ll stay feeling full for longer.

In addition, your appetite will be drastically reduced because the part of the stomach that produces much of the hunger hormone, ghrelin, is removed. 

On average, 12 to 18 months after surgery, you will lose 65% of the extra weight you’re carrying above your estimated normal body weight.

What happens during sleeve gastrectomy surgery?

At Blackrock WeightCare, we can perform sleeve gastrectomy surgery laparoscopically (keyhole) or robotically using the da Vinci Xi robotic surgical system under general anaesthesia.

During the operation, a surgical stapling device is used to staple and seal your stomach. We also use a guide tube to measure the size of the stomach sleeve that’s left behind. About 70% of your stomach is permanently removed, which leaves behind a narrow ‘banana-shaped’ stomach – the sleeve. We don’t remove or bypass any intestines during this surgery, and the surgery usually takes about one hour to perform.

Sleeve Gastrectomy Frequently Asked Questions

Your surgeon could recommend a sleeve gastrectomy as the best operation for you to have successful and sustained weight loss. Also, if your BMI is very high, a sleeve gastrectomy could be used as an initial surgery to help you lose enough weight to undergo a more extensive weight loss operation. Sleeve gastrectomy may also be a safer choice if you are older or have other risk factors such as heart, lung or liver problems. It provides really good results in terms of weight loss but is a shorter operation which can be beneficial for patients who are a higher surgical risk.

Sleeve gastrectomy surgery reduces the risk of potentially life-threatening complications related to obesity, such as diabetes, sleep apnoea, and high blood pressure. These conditions can significantly reduce or often will be completely resolved after a sleeve gastrectomy. This means that your overall health, wellbeing and quality of life will be significantly improved after surgery.

Sleeve gastrectomy cannot be reversed because a part of your stomach will be removed. It is a permanent operation.
