There is no doubt that obesity is an epidemic that affects not only developed but also underdeveloped countries. This “globalization” of the disease has led to the current surgery, as a therapeutic method of this pathology, to evolve in terms of its techniques implemented to patients [1]. Within these evolutions is the single anastomosis gastric bypass (SAGB) too called one-anastomosis gastric bypass (OAGB), which although it has few years of application, many centers of the world have adopted it successfully with good results. This technique has about 15 years, but it is in the last 5 years in which it showed a surprising development [2]. It consists of performing a gastric pouch and a single gastroenteroanastomosis, without Roux-en-Y reconstruction. In this way surgery is achieved with equal or better results with a less anastomosis and all that implies.

We will then develop the technique, results, and conclusions.
