Like the classic gastric bypass, this too is a 'gastric bypass' operation. However, in this operation a very long stomach pouch is fashioned like the sleeve, (by disconnecting from the remnant stomach) and is connected to a loop of the intestine, at about 2 meters length from the latter's starting point. So there is only one connecting anastomosis (instead of two, as in the classic gastric bypass), hence called the “mini” gastric bypass. This reduces the time of operation and complications of intestinal obstruction, with comparable and sometimes, better results to the classic gastric bypass. This is now done in many parts of the world with good results for both, weight loss and diabetes remission. This procedure is also known with many other names like, the omega-loop gastric bypass, single anastomosis gastric bypass, etc., Some are skeptical because there is a potential risk of back flow (reflux) of the bile (intestinal secretions) into the stomach tube, which the classic bypass doesn’t have. So far, no evidence has shown this to be of any great risk. It is routinely done in Europe, Middle-east and South-east Asia, though less commonly done, in the US.
