Mini Gastric Bypass Surgery

As the name suggests, mini gastric bypass surgery (MGBP) is a simplified form of a standard gastric bypass surgery. The surgery uses a combination of restrictive and malabsorptive techniques to reduce the size of the stomach and alter hormones involved in appetite control.

It is also an operation which is gaining recognition for eradication of diabetes in insulin and non-insulin dependent patients.

Advantages of mini gastric bypass surgery

The mini gastric bypass was developed to reduce operating time, simplify the procedure and reduce complications. The procedure involves less re-routing of the intestines and fewer connection of intestines (anastomosis).

Studies which specifically evaluated the effectiveness of mini gastric bypass showed the procedure to be equally successful as a gastric bypass surgery.

How is mini gastric bypass surgery performed?

Mini gastric bypass surgery begins by dividing the stomach to create a small restrictive pouch and limit the amount of food taken at any one time.

This is followed by the surgeon joining the reduced stomach (between 150-200cm long) to the lower part of the bowel. This process is known as anastamosis.

Food bypasses between 60cm – 215cm of intestines before absorption of calories can take place and resumes the normal digestive process in the new tube-like stomach.

Preparing for mini gastric bypass surgery

Before the procedure Dr Dolan will run a series of tests to ensure patients are ready for surgery. Patients will also need to follow an eating plan set out by their surgeon and dietitian.

Dr Dolan will go over the specific instructions for preoperative care, but generally patients will need to:

  • Go on a liquid diet a week before surgery.
  • Be nil by mouth after midnight, the day before surgery.
  • Ask a friend or family member to be at the hospital for support and comfort.

What can I expect after mini gastric bypass surgery?

Post-surgery you may experience abdominal pain, particularly at your incision sites. You will typically be required to stay overnight in the hospital.

Before you are discharged, you will receive detailed instructions to help you care for your incisions and surgical area, and your follow-up date with Dr Dolan. We will also prescribe medication to aid in the healing process and reduce the risk of infection. It’s essential that you follow all instructions carefully to ensure the best possible outcome.

The average weight loss is approximately 50% in the first year and can increase to 80% by the third year following surgery. The results will vary and depend greatly on the patient’s ability to follow instructions, improve their lifestyle and their dietary habits.

What does mini gastric bypass surgery cost? Is there payment plans?

There are a number of factors which may influence the final cost of surgery. Dr Dolan will be able to provide a more detailed quote during your initial consultation.

Patients can choose from a variety of payment options available depending on their financial circumstances and insurance status.

  • Out of pocket expenses are $4,500 for insured patients.
  • It may also be possible to access your superannuation.
  • We offer flexible payment plans for patients.

Risks and complications

Complications are similar to gastric bypass surgery; however these are very rare under the prevision and expertise of Dr Kevin Dolan.

Preparing for your mini gastric bypass surgery should involve understanding the risks and symptoms of minor and major complications.

Minor complications can include ulcers, hernias at the surgical site, and minor incision infections.

Major complications can include staple line leaks, pulmonary embolisms, and strictures, among other risks. These typically occur within the first three weeks after surgery and should be addressed promptly by your surgeon.
