Mexico Bariatric Center® (MBC) is revolutionizing weight loss solutions with the introduction of the innovative SASI-S (Single Anastomosis Sleeve Ileal bypass) procedure. This advanced technique combines the benefits of a sleeve gastrectomy with an intestinal bypass, offering a powerful path to lasting weight loss and improved metabolic health.

MBC’s pioneer surgeon, Dr. Jacqui Osuna, offers this new and promising procedure to our patients exclusively.

SASI yields superior outcomes compared to Roux-en-Y (RNY) and mini-gastric bypass. It exhibits similar effectiveness to highly malabsorptive procedures such as duodenal switch (DS/BPD and SADI) with a simpler surgical approach, lower risk, reduced stomach pressure and malabsorption, and improved reversibility.

Get Sassy with SASI: A New Era in Bariatric Surgery

SASI-S Single Anastomosis Stomach-Ileal Bypass Schematic Mexico Bariatric Center-ProcedureLOVE-SASI-SThe SASI-S procedure is a variation of hypoabsorptive (ileal) procedures, designed to provide significant and sustained weight loss while addressing obesity-related conditions such as type 2 diabetes, hypertension, and sleep apnea. SASI-S stands out due to its simplified surgical approach, which involves reducing stomach size and creating only one anastomosis (connection). SASI’s simplified surgical technique and the preservation of the duodenum can contribute to a lower risk and side effects, including nutrient deficiencies, when compared to duodenal switch (DS/BPD) and single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S).

Beyond restriction and malabsorption, SASI-S triggers beneficial hormonal changes, including SADI-S, which help curb hunger and regulate blood sugar levels. Patients undergoing this procedure can expect to lose between 65%-75% of their excess weight in the first year alone, and a high percentage of type 2 diabetes patients experience remission after surgery.

SASI-S procedure is gaining recognition as a promising revisional bariatric surgery option for patients who have experienced challenges with previous surgeries, including lap band, gastric sleeve, and bypass. This procedure also stands out for its versatility, as it can be easily converted or revised if a patient’s needs change.
