Mini Gastric Bypass

The Mini gastric bypass is a newer form of gastric bypass surgery.

What is a Mini Gastric Bypass Procedure?

The Mini Gastric Bypass procedure is performed laparoscopically and again involves making the stomach smaller. In this operation there is only one anastomosis or join. It is slightly easier to perform and usually would take less time than a standard Roux-en -Y bypass.

It works by a mixture of restriction (with a small stomach) and malabsorption (as food bypasses 150-200cm of small bowel and cannot be absorbed in this section). Like all bariatric procedures there are advantages and disadvantages.

What are the advantages of a Mini Gastric Bypass?

  • Weight loss is similar to the standard Roux-en-Y and may be more than sleeve gastrectomy.
  • Because there is only one join, there is less potential for internal herniation and blockages that are known to occur after Roux-en-Y , sometimes years later.
  • Good results in the treatment and remission of Type 2 Diabetes.
  • Takes less time to perform, has a shorter learning curve and is associated with fewer major complications in the postoperative period.

What are the disadvantages of a Mini Gastric Bypass?

  • As a segment of bowel is excluded and there is a degree of malabsorption it will be important for patients to take multivitamin supplementation lifelong and attend for yearly follow up with blood tests to ensure there are no deficiencies.
  • The procedure is relatively new, commencing in 1997. Long term data is not yet available.
  • There are concerns about bile reflux, possible gastric ulceration and concerns about long term risk of stomach or oesophageal cancer. No evidence yet exists to show an increase in cancers though.

Who is a candidate for a Mini Gastric Bypass (MGB)?

We currently see MGB as a potential option for sleeve patients battling weight regain. It is not an option for patients with significant reflux as it may make their reflux worse.
