Reclaim your life with gastric sleeve surgery

The sleeve gastrectomy (otherwise known as vertical sleeve gastrectomy or the gastric sleeve) is the most common weight-loss surgical procedure in Australia and worldwide. This safe and effective procedure makes up over 70% of all weight loss surgery procedures in Australia, so 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
Before and after gastric sleeve surgery

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.

If you’re struggling with weight loss and ready to take the next step towards a healthier lifestyle, a sleeve gastrectomy may be the perfect solution for you. Contact us today to learn more about this revolutionary procedure and schedule a consultation with Dr. Andrew Kiyingi.

Do you have any questions related to bariatric surgery in Perth? Talk to Dr Andrew Kiyingi today.


    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. Following years of experience, Dr Andrew Kiyingi’s has fine-tuned his pain management protocol and most patients would expect to only require simple pain relief within 72hrs of surgery.

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

    When can I drive After sleeve gastrectomy surgery?

    We recommend waiting at least 10 days following gastric sleeve surgery before driving. However if you still have pain or feel uncomfortable, it is advisable to wait a bit longer till that settles.

    Which hospitals does Dr Andrew Kiyingi perform bariatric surgery?

    Dr Andrew Kiyingi performs bariatric surgery at St John of God Subiaco (Subiaco), The Mount Hospital (Perth CBD), St John of God Murdoch (Murdoch) , St John of God Mt Lawley (Mt Lawley). Note that you may be allocated a SPECIFIC hospital depending on your underlying medical conditions and date of 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. If you go back to your old eating habits, then you may find that your weight returns also.

    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.
