Your guide to gastric sleeve surgery

Gastric sleeve surgery is the top weight-loss surgery not just in Australia, but globally. In fact, it accounts for over 70% of bariatric procedures. A minimally invasive procedure, it reduces your stomach to the size of a banana (around 150-200ml) and lowers your hunger hormone levels, meaning you feel full with smaller meals.

During your sleeve gastrectomy, Dr Andrew Kiyingi inserts a narrow tube called a ‘bougie’ into your stomach as a sizing guide. He carefully staples along this guide, ensuring each staple forms a tight seal. This precise technique maximises success and minimises complications, ensuring your new stomach size is accurate for the best results.

After your surgery, you can expect significant weight loss over 12-18 months, leading to a healthier, more active lifestyle. With well over 1000 successful surgeries, Dr Andrew Kiyingi is one of Perth and Western Australia’s leading bariatric surgeons.

    These include:

    • Type 2 diabetes
    • Depression
    • Infertility both male and female
      • Obstructive sleep apnoea

    Bariatric surgery can help you achieve lasting results. These surgical procedures have continued to advance with research and technology and are safe and effective.

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

    Our patients consistently report some of the lowest pain levels among Perth gastric sleeve patients. With a focus on effective pain management, Dr Kiyingi has fine-tuned his protocol through years of experience. Most patients typically only need simple pain relief within 72 hours of surgery.

    What is the average operating time for sleeve gastrectomy surgery?

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

    What do recovery time frames look like?

    The average recovery time of sleeve gastrectomy surgery varies depending on the demands of your work. On average, expect two weeks off for office-based work.

    The average length of stay in hospital after gastric sleeve surgery is 1-2 nights.

    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.

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

    Dr Andrew Kiyingi uses medical-grade titanium miniature staples, not like office staples. Each cartridge of the stapling device fires 108 tiny staples–so small that you won’t set off metal detectors!

    Will I need a general anaesthetic for gastric sleeve surgery?

    All weight loss surgery, including gastric sleeve surgery, is performed under general anaesthesia, ensuring you’re completely asleep during the operation. Although general anaesthesia is very safe, we take extra medical precautions to ensure you’re fully prepared for surgery.

    Can I still get pregnant after a sleeve gastrectomy?

    Yes, you can still get pregnant after a sleeve gastrectomy, but it’s recommended to wait at least 18 months post-surgery. This allows your weight to stabilise and ensures a healthy, safe pregnancy.

    If obesity-related infertility is an issue, a gastric sleeve procedure can actually help increase fertility.

    What are the post-operative side effects of a gastric sleeve?

    Post-operative side effects of a gastric sleeve can include nausea, vomiting, acid reflux, and food intolerance. Some patients may experience difficulty swallowing, dehydration, or nutrient deficiencies.

    Rarely, there’s a risk of infection, bleeding, and blood clots. Long-term effects can include changes in bowel habits and possible weight regain if dietary guidelines aren’t followed.

    It’s important to stay in close contact with your medical team to manage and mitigate these side effects.
