Deciding to have surgery requires careful thought and discussion. Dr Andrew Kiyingi and his team can explain what each procedure involves & recommend the best one for you.

“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”

Omega loop bypass surgery is also known as Mini Gastric Bypass Surgery or Single Anastomosis Gastric Bypass Surgery. This procedure was developed 20 years ago and has increasingly become more popular due to its effectiveness in weight loss.

This process involves 2 main steps:

Similar to gastric sleeve surgery, the first step is creating a small stomach mini sleeve (also called pouch) and sealed off with a surgical stapler. This sleeve is slightly shorter in this case though.
The second step involved joining the small intestine to the lower end of the stomach pouch.

As a result, you will feel full soon while eating. However, because the intestine is attached to the stomach further along, the food essentially is able to take a shortcut through the small intestine and approximately 200cm of the small intestine is bypassed. As a result of this shortcut, less calories are absorbed after eating.

The mini gastric bypass surgery also has an significant effect on a range of digestive hormones. This results in:

Reduced hunger
Improved blood sugar control particularly in people with type 2 diabetes
A reset in the body’s normal weight range which is often known as the set-point.

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.

The Procedure

Following the completion of the pre-operative surgery programme everything will be in place for safe and successful surgery. It is natural to be anxious on the day of surgery. Rest assured that the Dr. Andrew Kiyingi has a reputation as a meticulous surgeon. Try to have a light and relaxed schedule the day prior to surgery and good night sleep. Please pay extra special attention to the diet and fasting instructions from our Specialist Bariatric Anaethetist. It’s important to note that fasting includes no chewing gum.

On the day of surgery, you will be again greeted by Dr. Andrew Kiyingi and his Specialist Anaethetist. Please feel free to ask any additional questions. The procedure is performed under general anaesthesia. The key-hole (laparoscopic) procedure involves making 6 small incisions (2cm) on your abdomen. Carbon dioxide gas will be used to expand your abdomen, allowing the organs to be seen. A special narrow camera called a laparoscope, will be inserted through one incision and a video image will be relayed to a tv screen to allow Dr. Andrew Kiyingi to perform the surgery. Further small instruments will be inserted through the other incisions as required to complete the operation. During surgery your liver will be gently lifted up to reveal the stomach. The stomach will then be carefully freed from its attachments and surrounding organs. Dr. Andrew Kiyingi will assess if you have a Hiatus Hernia defect and repair it if required (read more here). A stomach sizing guide called a bougie will then be passed into your stomach. This bougie ensures consistent and accurate sizing of your new smaller stomach pouch. Dr. Andrew Kiyingi with then carefully staples along this sizing guide ensuring that each staple forms a tight seal. This stapler will divide the old stomach from the new smaller stomach pouch. The old stomach is not removed and remains healthy in the abdomen but does not receive food.

Dr. Andrew Kiyingi will then accurately measure the small intestine and determine the appropriate length to bypass (usually 150 – 200cm). This loop of intestine is then brought up and joined to the small stomach pouch. A special leak test is then performed to ensure everything is secure. Dr. Kiyingi will then apply special local anaesthesia to minimise any discomfort following surgery.

At the end of the 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 till you are ready to return to the surgical ward. It is common to feel tired after surgery.
