Gastric Sleeve Perth

Gastric Sleeve Surgery for Weight Loss

The first step is easy.

“Weight loss (Bariatric) Surgery has significant health benefits such as reducing the risk of death from many causes. It is important to maintain a healthy lifestyle even after surgery”


Gastric Sleeve surgery (also known as Sleeve Gastrectomy) is one of the most commonly performed weight loss procedures.

A laparoscopic gastric sleeve involves a key hole (laparoscopic) surgery procedure that involves permanently removing a portion (approximately three quarters) of the stomach. It does not involve any re-routing of the intestine. As a result, the stomach size becomes much smaller (approximately 150mls), allowing the patient to feel full after eating only a small meal. Food passes as normal down the oesophagus, through the resized stomach and into the small intestine.

A gastric sleeve operation also leads to a reduction in the body’s hunger hormone called Ghrelin. As a result, patients also feel less hungry between meals.

Gastric Sleeve Surgery

It’s Not Just Weight Loss.
It’s Health Gain.

Being overweight or obese is one of the leading risk factors for ill health in Australia. The longer you live with obesity, the greater the negative effect on your physical health, mental health and wellbeing.

Unfortunately, diets won’t work for many people and this is when bariatric surgery (also known as weight loss or obesity surgery) can help you achieve lasting results. These surgeries have continued to advance with research and technology and are safe and effective.

Surgery works by influencing hunger and the way in which the body process food/calories. It is expected that following weight loss surgery, a patient is able to eat every day normal healthy food (in a smaller quantity), participate in normal every day activities and enjoy a great quality of life.

Your Gastric Sleeve Surgery

Your Gastric Sleeve Surgery

After the completion of the pre-operative surgery programme, everything will be in place for a safe and successful sleeve gastrectomy procedure. It is perfectly normal, and actually quite common to be nervous on the day of surgery. Dr Andrew Kiyingi’s reputation as a meticulous surgeon should help to relieve some of these anxieties.

Try to have a light and relaxed schedule the day prior to surgery and a good night’s sleep. Please pay extra attention to the diet and fasting instructions from our Bariatric Anaesthetist and please understand that fasting includes no chewing gum.

  • Feel free to ask further questions when you will be again greeted by Dr Andrew Kiyingi and his Specialist team on the day of surgery. The procedure is performed under general anaesthesia.

  • In the laparoscopic gastric sleeve procedure, Dr Kiyingi will make 5 small incisions (2cm) on your abdomen. To see organs clearly, carbon dioxide gas will be used to expand your abdomen.

  • An instrument with a special, narrow camera called a laparoscope, will be inserted through one incision to send pictures on a tv screen or monitor. It will allow Dr Andrew Kiyingi to perform the surgery.

  • Additional small instruments will be inserted through the other small incisions as required to complete the operation.

  • During gastric sleeve surgery, your liver will be gently lifted up and the stomach will then be carefully unbound from its attachments and surrounding organs.

  • A stomach sizing guide called a bougie will be passed into your stomach, to ensure consistent and precise sizing of your new gastric sleeve.

  • Then, weight loss surgeon, Dr Andrew Kiyingi, will carefully staple along this sizing guide ensuring that each staple forms a tight seal. This will divide the old stomach from the new gastric sleeve.

  • Once the old stomach is removed through one of your keyhole incisions, Dr Andrew Kiyingi will apply special local anaesthesia to minimise any discomfort following surgery.

  • At the end of the bariatric sleeve procedure, the incisions are closed with dissolving sutures and covered with a waterproof dressing.

The operation will be complete when you wake up and you will stay in the recovery unit for some time until you are ready to return to the surgical ward. It is normal to feel tired after surgery.

Gastric Sleeve Surgery After Care

Gastric Sleeve Surgery After Care

  • Dr Andrew Kiyingi will review you daily after your gastric sleeve operation. The average length of stay is about 2 nights, though this can vary and will be assessed on a case-by-case basis.

  • You will be kept relaxed with anti-nausea medications and pain relief. You will also be encouraged to do some gentle walking. Generally, patients report very little pain following surgery. However, we always try to make your stay more comfortable, so please feel free to inform the health care team if there is anything we can do.

  • Our specialist dietician will provide you with after-surgery diet information. Initially, this will involve a clear fluid diet provided by the hospital. For some patients, you can also bring some additional drinks of your choice.

Dr Andrew Kiyingi will review again at the time of your hospital discharge and answer your additional questions. Once you arrive home you can begin taking your twice-daily chewable multivitamin (BN Brand only).

It will be essential to follow the dietary, protein and fluid advice suggested by our experienced dietician and surgeon. Many patients enjoy casual comfortable walks each day. We know that you will have enough on your mind at this part of your recovery so we generally recommend hiding your scales for now!

Frequently Asked Questions (FAQs)

What is a sleeve gastrectomy procedure?

A sleeve gastrectomy (also known as gastric sleeve surgery or bariatric sleeve), is a procedure in which the surgeon removes around 75% of the patient’s stomach. This leaves what is often referred to as a small “sleeve” of the remaining stomach, which then connects to the intestines of the patient. Ultimately, it aims to reduce the amount of food that the stomach can hold, helping to reduce the appetite of patients, and leading to more benefits in the long term.

Is a sleeve gastrectomy permanent?

Yes, a sleeve gastrectomy is a permanent procedure, as the GSA surgeons remove part of your stomach in the operation. This is one of the key differential factors between gastric sleeve surgery and other options, in particular the lap band surgery. Some patients don’t like the permanency of the operation, and may decide on a different bariatric surgery because of this fact. 

Is a sleeve gastrectomy and lap band the same thing?

Although both surgeries involve the reduction of the stomach space, helping people to eat less food, a sleeve gastrectomy and a lap band surgery are two very separate procedures. Whilst the sleeve gastrectomy procedure involves the removal of part of the stomach, a lap band surgery instead involves the placement of a small band around the stomach. This band then creates two different sections in the stomach: a smaller upper pouch, and a larger lower section. The band itself can be adjusted over time, to help tighten the band and increase the efficacy, or may even be removed altogether.

A sleeve gastrectomy tends to see more effective weight loss than lap band surgery, and does not involve a rerouting of the digestive process. The problem that many patients see with a lap band surgery is that they don’t lose a significant amount of weight, with some patients actually seeing an increase in their weight over the years.

Is sleeve gastrectomy arthroscopic or laparoscopic?

A sleeve gastrectomy is not an arthroscopic procedure, as it does not involve doctors treating an issue inside a joint (arth = joint). However, it is a minimally invasive operation, where the surgeon only needs to make a few incisions. In this respect, it is known as a key-hole surgery, or a laparoscopic gastric sleeve.

Can I still get pregnant after a sleeve gastrectomy?

Yes, you can still get pregnant after a sleeve gastrectomy procedure, though it is recommended that you wait at least 18 months before trying to get pregnant. This allows an adequate amount of time for your weight to stabilise after the surgery, ensuring you can have a healthy and safe pregnancy. In some circumstances, if a woman’s infertility was related to her obesity, a gastric sleeve operation can actually help her to get pregnant.
