Gastric Sleeve Surgery for Weight Loss

Experience long-lasting transformation with vertical gastric sleeve surgery

What is Gastric Sleeve Surgery?

The sleeve gastrectomy (otherwise known as the vertical sleeve gastrectomy or the gastric sleeve) is the most common weight-loss surgical procedure in Australia and worldwide. In fact, it makes up over 70% of all weight loss surgery procedures in Australia, so it’s nice to know you are not alone. With experience in well over 1000 successful cases, Dr Andrew Kiyingi is one of the leading bariatric surgeons specialising in gastric sleeve surgery in Perth and Western Australia.

A sleeve gastrectomy is a weight-loss surgical procedure on your stomach performed through small keyhole incisions which:

  • Firstly, reduces the size of the stomach, leaving you with a new small narrow stomach about the size and shape of a banana (approximately 150ml)
  • Secondly, reduces the level of the body’s hunger hormone called Ghrelin

During the sleeve gastrectomy procedure, Dr Andrew Kiyingi passes a narrow flexible tube into your stomach. This is called a “bougie” and this acts as a sizing guide for your new stomach. He then carefully staples along this sizing guide so that each staple forms a tight seal. This technique ensures that all the sleeve gastrectomy surgeries Dr Andrew Kiyingi performs are measured to the correct size to maximise success and minimise complications.

If the gastric sleeve is made too tight, problems such as swallowing and vomiting can develop. Conversely, if the sleeve gastrectomy is too loose and your stomach volume is too large, this can result in poor weight loss or very early weight regain.

The sleeve gastrectomy procedure achieves weight loss by allowing you to:

  • Eat smaller meals of normal food and still feel full
  • Feel less hungry between meals

Following your gastric sleeve surgery, you can expect to lose weight over the first 12 to 18 months. After which you will maintain your new lower weight through a healthy active lifestyle and enjoy a great quality of life.

Sleeve Gastrectomy is 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. In fact, there are over 230 medical conditions linked to obesity and many people may not even be aware that they already suffer from them.

These include:

  • Type 2 diabetes
  • Depression
  • Infertility both male and male
  • Obstructive sleep apnoea
  • Heart disease
  • High blood pressure (hypertension)
  • Stroke
  • Joint problems such as osteoarthritis and gout
  • Some cancers including breast and colon (bowel) cancer
  • Polycystic ovarian syndrome
  • Liver disease

Just to name a few. Many of these conditions will have a long-term impact on your quality of life and shorten your life expectancy. Bariatric surgery (also known as weight loss or obesity surgery) can help you achieve lasting results. These surgical procedures have continued to advance with research and technology and are safe and effective.

During the journey you will meet our whole team including Dr Andrew Kiyingi and our specialist dietician and physician. We will organise the necessary medical investigations required for your safe surgery.

What happens on the day of your gastric sleeve surgery?
  • After the completion of the pre-operative surgery programme, you will be ready for a safe and successful sleeve gastrectomy procedure. It is perfectly normal 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.

  • Feel free to ask further questions when you will be again greeted by Dr Andrew Kiyingi and his team on the day of surgery.
What happens on during your Sleeve Gastrectomy Operation?
  • The sleeve gastrectomy is performed under general anaesthesia.
  • Dr Kiyingi will make 5 small (key-hole) 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.
  • Dr Andrew Kiyingi, will then 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.
  • When you wake up, 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.
Your 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.

Diet after Your Gastric Sleeve

Firstly, rest assured that you will be able to comfortably eat normal everyday food once your gastric sleeve has healed after 8-10 weeks following surgery. You should not expect to suffer with recurrent vomiting unlike old fashioned weight loss procedures such as the gastric band.

Our specialist dietician will provide you with a staged diet plan, starting with a high protein fluid diet for the first 2 weeks following surgery. From then you will follow the plan and slowly upgrade food textures over approximately 2 weekly intervals over 8 – 10 weeks till you resume a normal diet. Strictly adhering to this post gastric sleeve surgery diet plan is critical to avoid complications from surgery in the weeks after surgery.

Frequently Asked Questions (FAQs)

What is a sleeve gastrectomy procedure?

A sleeve gastrectomy (also known as gastric sleeve surgery or bariatric sleeve), is a laparoscopic keyhole surgery 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 “outer” portion of the stomach is permanently removed leaving behind a stomach that is 75-80% smaller. The permanent change in the stomach following gastric sleeve surgery provides more durable long term weight loss results compared to less effective “temporary” weight loss options such as medications and gastric banding.

Will I be in a lot of pain after gastric sleeve surgery?

Dr Andrew Kiyingi patients routinely experience some of the lowest pain level among Perth gastric sleeve patients. Effectively managing pain is a priority during your operation.

1 – 1.5 hours is the average operating time for sleeve gastrectomy surgery.

What is the Average recovery time off work sleeve gastrectomy surgery?

What are the staples used during gastric sleeve surgery made of?

Medical-grade titanium. They are miniature staples, unlike the staples in your office. A single cartridge of the stapling device fires 108 staples. Don’t worry they are so small that you won’t set off any metal detectors.

How do I avoid regaining weight after Gastric Sleeve Surgery?

This is a very complex topic; however, good healthy food habits everyday are the key preventing weight regain after Sleeve Gastrectomy surgery. Attending regular ongoing follow-ups with your surgical team has been shown to reduce the risk of regaining weight. Also, avoiding habits of snacking and high sugar and high alcohol foods is important. Weight loss surgery is only the start of your weight loss journey.

Will I need a General Anaesthetic for Gastric Sleeve Surgery?

All weight loss surgery including sleeve gastrectomy is performed under general anaesthetic which means you will be completely asleep and when you wake up the operation will be complete.

Even though general anaesthetic is very safe, at Perth Bariatric Surgery undertake additional medical preparation is to ensure you are fully prepared.

Is a sleeve gastrectomy and lap band the same thing?

No. Whilst the sleeve gastrectomy procedure involves the removal of part of the stomach, a lap band surgery instead involves the placement of a tight silicone 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 is a more effective weight loss surgery than lap band surgery, without the additional complications of lap band surgery such as extreme vomiting and food intolerance.

Is sleeve gastrectomy arthroscopic or laparoscopic?

A sleeve gastrectomy a laparoscopic procedure, which refers to “key-hole”, not arthroscopic procedure which refers to inside a joint (arth = joint). Gastric Sleeve surgery is a minimally invasive operation, where the surgeon only needs to make a few small incisions.

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 increase fertility.
