Schematic diagram of uncut Roux-en-y anastomosis (URYA). URYA includes an end-to-side gastrojejunostomy which was constructed approximately 20 cm distal to Treitz ligament and a “Braun enteroenterostomy” which was performed by joining the afferent to efferent limb about 10 and 35 cm away from gastrointestinal anastomosis, respectively, and then the afferent limb was occluded 3 cm away from gastrointestinal anastomosis. a Represented iso-URYA and b represented anti-URYA. For both a, b, A represented duodenal stump; B represented Braun enteroenterostomy; C represented afferent occlusion; D represented gastrointestinal anastomosis; E represented efferent loop
