Mini Gastric Bypass

The One Anastomosis Gastric Bypass (OAGB) operation is increasingly popular among some surgeons around the world. As seen from the diagram it is a type of Gastric Bypass that uses only one join to the new gastric pouch formed by surgically stapling the stomach. The traditional Roux en Y version of Gastric Bypass (RYGB) uses two joins. OAGB used to be called the Mini Gastric Bypass (MGB) because in the era before laparoscopic (keyhole) surgery it was done via a smaller incision than the RYGB.

Advantages and Disadvantages

Weight loss with the two procedures appears very similar or possibly more with OAGB but we don’t yet know how safe it is. Studies are being done to work this out. A potential advantage of OAGB is that it is easier to do but it may not be possible in everyone. You should talk to your surgeon about this. Potential disadvantages include reflux of bile and digestive juices back into the stomach and gullet which can cause unpleasant symptoms such as heartburn. Another potential disadvantage of OAGB compared to RYGB is that because a longer limb of bowel is used to make the join it could lead to problems with vitamin and micronutrient deficiencies or malnutrition if there is not enough bowel left for adequate absorption.

What are the risks?

Immediate postoperative complications are similar to the RYGB with a reoperation rate of about 3% due to problems such as bleeding, bowel obstruction and staple line leakage. All need prompt management by your surgical team. Other major complications include deep vein thrombosis and blood clots to the lungs (pulmonary embolism). Minor complications include minor wound infections and ulcers. It is important to be aware of the possible complications with all types of surgery.

The operation

The Mini Gastric Bypass operation is performed using laparoscopy keyhole surgery; it is a major operation lasting one and a half hours. You can expect your hospital stay to be two nights, with a recovery time of two to four weeks before you can go back to work.

The operation involves the creation of a pouch, essentially stapling the stomach to make it smaller; this is then connected to the intestine, bypassing the remaining stomach which allows food and beverages to only enter the new smaller stomach.


Two year Mini Gastric Bypass aftercare support package:

  • Access to our specialist weight-loss team, which includes Bariatric Surgeons, Dietitians and Nurses.
  • 24-hour emergency telephone helpline.
  • Post-operative assessment.
  • Six months surgical cover.

You and the future

Prior to having the operation we recommend that you follow our pre-operative diet (also commonly known as the liver reducing diet) to minimise risk and to prepare you for the lifestyle change required after the surgery.

We have an excellent unlimited two year aftercare package to ensure you are fully supported from the start and throughout your journey.
