What is a Mini Gastric Bypass?

The ‘Mini Gastric Bypass’ or, more accurately, the One Anastomosis Gastric Bypass is a simplified version of the Standard Roux-en-Y Gastric bypass that has become popular in recent years due to its reduction in technical difficulty and operating time. In this surgery, a new, small stomach is made which is joined to the small intestine bypassing 1.5 to 2 metres of small intestine without dividing the bowel. There is some data suggesting weight loss outcomes may be equivalent to the traditional Gastric bypass, however the data is not conclusive. We are happy to discuss the latest evidence, risks and benefits of this technique and whether this would be suitable for you.
