The Roux-en-Y Gastric Bypass (RYGB) is the procedure of choice in morbid obesity with metabolic disorders in most of the reference centers. Recent data describes the SASI Bipartition as being as efficient on weight loss and co-morbidities as the RYGB, with the advantage of being less technically difficult and less morbidity. In order to draw definite conclusions regarding the procedure, larger series with longer follow-up are necessary.~Patients with BMI over 40, or with BMI over 35 with comorbidities are offered SASI Bipartition with 300 cm common limb or standard RYGB. Follow up is performed through visits at 3, 12, 24, 36, 48, and 60 months after surgery.~Results on weight loss, comorbidities resolution, complications, and need of supplements are registered.
The main aim of this project is to assess the safety and efficiency of the SASI Bipartition.
