Treatment Overview
Single Anastomosis Duodeno‑Ileal Bypass with Sleeve Gastrectomy (SADI‑S) in Korea is an advanced bariatric procedure designed for patients with severe obesity and metabolic disorders. The surgery combines a sleeve gastrectomy with a single intestinal bypass, connecting the duodenum to the ileum. This approach restricts stomach capacity while reducing nutrient absorption, leading to significant weight loss and improvement in metabolic health.
Korean hospitals perform SADI‑S using minimally invasive laparoscopic or robotic-assisted techniques. The procedure is supported by multidisciplinary care, including nutritionists, endocrinologists, and physiotherapists, ensuring comprehensive treatment for both local and international patients.
Purpose & Benefits
The primary purpose of SADI‑S is to provide effective weight loss and metabolic improvement for patients with severe obesity.
Key benefits include:
- Substantial and sustained weight loss
- Significant improvement or resolution of type 2 diabetes, hypertension, and dyslipidemia
- Hormonal changes that promote satiety and reduce appetite
- Minimally invasive surgery with smaller incisions and faster recovery
- Reduced long-term risk of cardiovascular and metabolic complications
- Enhanced energy, mobility, and overall quality of life
- Single anastomosis technique reduces surgical complexity compared to traditional duodenal switch procedures
Ideal Candidates
SADI‑S is suitable for patients who:
- Have a Body Mass Index (BMI) ≥ 40, or ≥ 35 with severe obesity-related comorbidities
- Require both restrictive and malabsorptive effects for optimal weight loss
- Have not achieved sufficient results with lifestyle interventions or previous bariatric surgery
- Are medically fit for surgery and committed to lifestyle modifications post-operatively
- Seek long-term improvement in metabolic disorders alongside weight reduction
Korean hospitals offer advanced care programs, making it ideal for international patients seeking complex bariatric solutions.
Possible Risks & Complications
Although generally safe, SADI‑S carries potential risks:
- Bleeding or infection
- Anastomotic leaks
- Nutritional deficiencies due to reduced absorption of proteins, vitamins, and minerals
- Gastrointestinal complications such as diarrhea, dumping syndrome, or reflux
- Rare complications including blood clots or anesthesia-related events
Korean bariatric centers perform meticulous pre-operative evaluations and provide nutritional planning to minimize risks and ensure safe outcomes.
Techniques & Technology Used
SADI‑S in Korea is performed using advanced laparoscopic or robotic-assisted techniques, featuring:
- High-definition laparoscopic cameras for precision
- Stapling devices and single anastomosis techniques for safe intestinal connection
- Pre- and post-operative nutritional assessment and supplementation
- Monitoring of metabolic health, weight progress, and post-operative recovery
Pre-operative preparation includes lab tests, imaging, and metabolic evaluation, while post-operative care emphasizes diet progression, supplementation, and lifestyle guidance.
Treatment Process in Korea
- Consultation & Assessment: Evaluation of medical history, BMI, metabolic health, and prior surgeries if applicable.
- Pre-Operative Preparation: Nutritional counseling, lab tests, and metabolic assessment.
- Surgery: Laparoscopic or robotic-assisted SADI‑S, typically lasting 2–3 hours.
- Hospital Stay: Usually 3–5 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Follow-up visits to monitor weight, metabolic parameters, nutrient levels, and lifestyle adherence. International patients are assisted with travel arrangements and care coordination.
Recovery & After-Care
Recovery involves:
- Mild post-operative discomfort managed with medications
- Gradual return to normal activities within 1–2 weeks
- Adherence to post-operative diet, supplementation, and exercise program
- Regular monitoring of weight, blood sugar, lipid profile, and nutrient levels
- Long-term guidance for maintaining weight loss and metabolic improvements
Structured post-operative care ensures safe recovery and optimal long-term results.
Results & Longevity
Patients can expect:
- Significant weight loss, often exceeding 70% of excess body weight within 12–18 months
- Resolution or improvement of obesity-related comorbidities
- Enhanced energy, mobility, and overall quality of life
- Long-term maintenance of weight and metabolic health with adherence to dietary and lifestyle recommendations
Results depend on individual health, surgical complexity, and commitment to follow-up care.
