Treatment Overview
Single Anastomosis Duodeno‑Ileal Bypass with Sleeve Gastrectomy (SADI‑S) is an advanced bariatric and metabolic surgery designed for patients with severe obesity and metabolic disorders. The procedure combines a sleeve gastrectomy with a single intestinal bypass, connecting the duodenum directly to the ileum. This reduces stomach size, limits calorie absorption, and promotes hormonal changes that improve appetite control and blood sugar regulation.
In Korea, SADI‑S is offered at specialized bariatric centers using minimally invasive laparoscopic or robotic-assisted techniques. It is particularly suitable for patients requiring significant weight loss or those who have not achieved sufficient results from previous bariatric procedures. Korean clinics provide experienced surgeons, state-of-the-art technology, and comprehensive care tailored to both domestic and international patients.
Purpose & Benefits
The main purpose of SADI‑S is to achieve maximum weight loss and improve metabolic health.
Key benefits include:
- Significant and sustained weight reduction
- Improvement or resolution of type 2 diabetes, hypertension, and dyslipidemia
- Hormonal regulation that reduces appetite and enhances satiety
- Minimally invasive approach with reduced recovery time
- Enhanced nutrient absorption control to prevent weight regain
- Long-term improvement in quality of life, mobility, and overall health
Ideal Candidates
SADI‑S is ideal for patients who:
- Have a Body Mass Index (BMI) ≥ 50, or ≥ 40 with obesity-related comorbidities
- Require advanced metabolic benefits beyond standard sleeve gastrectomy or duodenal bypass
- Have experienced insufficient weight loss with previous bariatric procedures
- Are medically fit and committed to lifelong dietary and lifestyle adjustments
International patients benefit from Korea’s expertise in complex bariatric surgeries, advanced technology, and dedicated medical tourism support.
Possible Risks & Complications
While generally safe, SADI‑S carries potential risks including:
- Bleeding or infection
- Staple line leaks or complications at the intestinal connection
- Nutritional deficiencies if post-operative guidelines are not followed
- Gastrointestinal discomfort or diarrhea
- Rare complications such as blood clots or anesthesia-related reactions
Korean clinics conduct comprehensive pre-operative assessments, imaging, and nutritional counseling to minimize risks and ensure patient safety.
Techniques & Technology Used
Korean bariatric centers use advanced laparoscopic and robotic-assisted techniques for SADI‑S, allowing precise sleeve formation and intestinal bypass with minimal invasiveness.
Pre-operative preparation includes lab tests, imaging studies, endoscopy, and nutritional assessment. Post-operative care focuses on diet progression, vitamin and mineral supplementation, and close monitoring to optimize weight loss and metabolic outcomes.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI, comorbidities, and prior surgeries if applicable.
- Pre-Operative Preparation: Nutritional counseling, lab tests, and lifestyle guidance.
- Surgery: Laparoscopic or robotic-assisted sleeve gastrectomy with single anastomosis duodeno-ileal bypass, typically lasting 2–3 hours.
- Hospital Stay: Usually 4–6 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Gradual diet progression, regular follow-up, and long-term lifestyle counseling to maintain weight loss and metabolic improvements.
International patients are supported by coordinators for travel, hospital admission, and post-operative care.
Recovery & After-Care
Recovery involves:
- Mild post-operative pain managed with medications
- Gradual return to daily activities within 1–2 weeks
- Adherence to strict dietary guidelines and nutritional supplementation
- Regular follow-up to monitor weight loss, nutrient levels, and health improvements
Patients are advised to maintain physical activity and lifelong lifestyle modifications for optimal outcomes.
Results & Longevity
Patients can expect:
- Significant and sustained weight loss exceeding standard bariatric procedures
- Improvement or resolution of type 2 diabetes, hypertension, and other metabolic disorders
- Enhanced hormonal regulation and appetite control
- Long-term benefits in mobility, energy, and overall health
Results vary depending on individual health, adherence to post-operative care, and lifestyle adjustments.
