This surgical technique is used in obesity patients with diabetes mellitus and in revision and conversion procedures.
In this surgical technique, in the first phase, stomach is incised from incisura angularis, stomach capacity is reduced and tube-shape is given. In the 2nd phase, small intestine is specified between 150-200 cm on average (this length varies depending on body mass index, diabetes mellitus presence, total length of small intestine and metabolic rate of the patient). In 3rd phase, single anastomosis (connection) is applied between specified small intestine part and stomach, so that food entering the stomach passes with bypass through the that part of the small intestine.
