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.
Mini gastric bypass, one anastomosis gastric bypass (OAGB), single anastomosis gastric bypass and omega loop gastric bypass are all names for the same operation. Despite the name, it is not a smaller or lighter version of weight loss surgery. It is a full bariatric procedure, performed as keyhole surgery by our Melbourne bariatric surgeons with two bariatric trained surgeons at every operation.

It remains major surgery with its own risks and benefits, which our surgeons will discuss with you against the traditional Roux-en-Y gastric bypass.
Patients typically lose 65 to 80 per cent of their excess weight within 12 to 18 months. Individual results vary, and long term success depends on the lifestyle changes our multidisciplinary team supports you through.
