Non-randomized Prospective Comparison Between SASI Bipartition and RYGB

SASI Bipartition is performed with a sleeve gastrectomy over a 32 French gastric bougie and a 300 cm common limb. Side-to-side gastroileostomy with a diameter of approximately 2.5 cm at the anterior part of antrum, 6 cm proximal to pylorus.

A small gastric pouch (15 mL) is created, and the jejunum brought up as an antecolic and antegastric fashion. Routine limb lengths were 150 cm for the alimentary limb and 60 cm for the bilio-pancreatic limb. Both mesenteric defects are closed with the Endohernia® stapler.
