At Brisbane General & Obesity Surgery, one of our most routinely performed surgeries is the mini gastric bypass / one anastomosis gastric bypass, making up almost half of the procedures performed by our surgeons.
Our selection process for this procedure ensures our excellent results, exceptionally low complication rate and nutritional safety amongst our patients.
Gastric bypass can help a person lose excess weight dramatically, lowering the risk for high blood pressure, sleep apnea, and certain heart problems. It can even reverse Type 2 diabetes.
Dr Jason Wong and his team of surgeons can assess your needs and advise you on whether this procedure is right for you.
Rest assured, Dr Wong’s safety record is exceptional and so are his results.
The internationally recognised name for this procedure is One-Anastomosis Gastric Bypass.
One-anastomosis gastric bypass bypass surgery is also known as mini gastric bypass, single-anastomosis gastric bypass and omega-loop bypass. It is a low-risk procedure that aims to treat obesity by reducing the size of the stomach and rearranging gastrointestinal anatomy to limit food consumption and appetite.
The procedure should also increase satiety, helping patients feel fuller faster, and for longer. This is our procedure of choice for treating patients with higher BMI, severe obesity and metabolic disease such as diabetes. We’ll assess your circumstances, medical history and goals to determine if this procedure is right for you.
The mini gastric bypass is a stronger metabolic procedure than a gastric sleeve and is performed for patients who have a BMI over 35 with comorbidities, or a BMI greater than 40.
If patients have a higher BMI, poorly controlled Type 2 Diabetes, or other poorly-controlled weight-related comorbidities, mini gastric bypass surgery can be a more effective procedure than a sleeve gastrectomy. Gastric bypass is more effective in the treatment of Type 2 diabetes than any medication that exists. That said, every patient is different. We can help determine your suitability for any of our procedures after an in-depth consultation and medical assessment.
After this procedure, most of our patients stay in hospital for just one night. Before the procedure, they will be given detailed instructions on post-surgery care. Pain is well controlled. Most patients simply need paracetamol or occasionally may need stronger pain relief.
After surgery, you will be on a liquid diet for two weeks. However, you will have the support of a dedicated dietitian who will advise you on what to expect before your procedure. Afterwards, they will review your post-surgery diet. They will also provide ongoing care and follow-up after surgery to guide you through your new and modified eating plan.
Eventually, patients who have undergone a mini gastric bypass surgery should be able to eat most normal, healthy foods in significantly reduced portion sizes. Sugary foods or too many carbohydrates may cause diarrhoea (dumping) or lower blood sugars (postprandial hypoglycemia). However, your dietician will be able to assist and support you to modify your diet and activity as needed in the post-surgery phase.
Some patients who receive a mini gastric bypass can get bile reflux. However, only 1% of Dr Wong’s OAGB-MGB patients end up having reflux symptoms. This low rate is achieved by using a good surgical technique for this procedure and ensuring an excellent patient selection process is maintained.
If you think a mini gastric bypass surgery may be suitable for you, we will conduct a medical assessment and in-depth consultation to see which procedure might suit your needs. Before committing to any of our procedures, our doctors always ensure our patients are fully informed with information about the process.
