The SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy) is an advanced bariatric procedure for patients with severe obesity or those who haven't achieved adequate results from other weight loss surgeries. Dr. Murat Üstün performs this procedure at Liv Hospital Vadistanbul. SADI-S combines a sleeve gastrectomy with intestinal bypass, offering superior weight loss results particularly for patients with a BMI over 50 or those with metabolic conditions like type 2 diabetes.
