SADI-S

Service Description

SADI-S: Single Anastomosis Duodeno–Ileal Bypass with Sleeve A modern, powerful option for weight loss and metabolic disease The SADI-S procedure (Single Anastomosis Duodeno–Ileal Bypass with Sleeve Gastrectomy) is a powerful, next-generation bariatric and metabolic surgery that combines Vertical Sleeve Gastrectomy (VSG) with a simplified version of the Duodenal Switch. 🔍 What is SADI-S? SADI-S is a hybrid bariatric surgery that: - Starts with a Vertical Sleeve Gastrectomy, reducing the stomach volume. - Then reroutes a portion of the small intestine with a single duodeno–ileal anastomosis (unlike the traditional biliopancreatic diversion with duodenal switch, which has two). - This results in restriction (less food intake) and malabsorption (less nutrient and calorie absorption), making it one of the most potent metabolic procedures currently available. 🔧 How the Anatomy Works - The sleeve restricts food intake. - The duodenum is transected just past the pylorus. - A loop of the ileum (typically 250–300 cm from the ileocecal valve) is connected to the duodenum—creating one anastomosis. - The food bypasses much of the jejunum, reducing calorie and fat absorption. ✅ Advantages of SADI-S - Superior weight loss (often >85% of excess weight) - Very high remission rates of type 2 diabetes (up to 95% in some series) - Single anastomosis = fewer complications than classic DS - Preserves pylorus → reduced dumping syndrome - Excellent durability for long-term weight control - Fewer bowel movements than classic BPD-DS ⚠️ Considerations / Risks - Vitamin and mineral deficiencies (requires strict lifelong supplementation) - Risk of diarrhea or steatorrhea (fatty stools) - Not recommended for patients who won’t adhere to close follow-up - Protein malnutrition risk if dietary compliance is poor - Not currently FDA-approved in the U.S., but commonly performed under IRB or internationally Ideal Candidates - BMI >50 or super-obese patients - Patients with poor glycemic control or metabolic syndrome - Those needing a revisional surgery after failed VSG - Compliant patients committed to long-term follow-up 📍 In Summary SADI-S is a powerful and simplified metabolic surgery option for severe obesity and metabolic disease. It combines the simplicity of a single anastomosis with the efficacy of duodenal switch physiology—making it an excellent option for experienced surgical centers and committed patients.
