Treatment Overview
Sleeve Gastrectomy with Duodenal Bypass is an advanced bariatric surgery that combines vertical sleeve gastrectomy with a partial bypass of the duodenum to enhance weight loss and improve metabolic health. The procedure reduces stomach size while rerouting the small intestine, limiting calorie absorption and promoting hormonal changes that aid in appetite control and blood sugar regulation.
In Korea, this surgery is performed at specialized bariatric centers using minimally invasive laparoscopic or robotic-assisted techniques. It is particularly suitable for patients with severe obesity or those with obesity-related conditions like type 2 diabetes who require more effective metabolic outcomes. Korean clinics offer experienced surgeons, advanced technology, and comprehensive pre- and post-operative care for both domestic and international patients.
Purpose & Benefits
The main purpose of sleeve gastrectomy with duodenal bypass is to achieve significant weight loss and improve obesity-related metabolic disorders.
Key benefits include:
- Enhanced weight reduction compared to standard sleeve gastrectomy
- Improvement or resolution of type 2 diabetes, hypertension, and dyslipidemia
- Hormonal regulation that reduces hunger and improves satiety
- Minimally invasive procedure with faster recovery
- Reduced risk of obesity-related complications
- Long-term improvement in quality of life, mobility, and energy levels
Ideal Candidates
This surgery is ideal for patients who:
- Have a Body Mass Index (BMI) ≥ 40, or ≥ 35 with significant obesity-related comorbidities
- Require enhanced metabolic benefits beyond standard sleeve gastrectomy
- Have experienced insufficient weight loss with previous bariatric procedures
- Are medically fit and motivated to follow post-operative lifestyle changes
International patients seeking advanced bariatric and metabolic surgery can benefit from Korea’s high standards and comprehensive medical tourism support.
Possible Risks & Complications
Although generally safe, the surgery carries potential risks including:
- Bleeding or infection
- Leakage at the staple line or duodenal connection
- Nutritional deficiencies if post-operative diet and supplementation are not followed
- Gastrointestinal discomfort, reflux, or dumping syndrome
- Rare complications such as blood clots or anesthesia reactions
Korean clinics perform thorough 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 sleeve gastrectomy with duodenal bypass. These approaches allow precise resection of the stomach and careful rerouting of the duodenum with minimal invasiveness.
Pre-operative preparation includes endoscopy, imaging, lab tests, and nutritional counseling. Post-operative care involves diet progression, vitamin and mineral supplementation, and close monitoring for complications.
Treatment Process in Korea
- Consultation & Assessment: Review of medical history, BMI, comorbidities, and prior surgical records if applicable.
- Pre-Operative Preparation: Nutritional guidance, lab tests, and lifestyle instructions.
- Surgery: Laparoscopic or robotic-assisted sleeve gastrectomy with partial duodenal bypass. Procedure generally takes 2–3 hours.
- Hospital Stay: Typically 3–5 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Gradual diet progression, regular follow-up, and lifestyle counseling for long-term weight management and metabolic health.
International patients are supported by coordinators who assist with hospital admission, travel arrangements, and post-operative care.
Recovery & After-Care
Recovery generally includes:
- Mild pain and discomfort managed with medication
- Gradual return to daily activities within 1–2 weeks
- Strict adherence to dietary guidelines, portion control, and supplementation
- Regular follow-up to monitor weight loss, nutrient levels, and health improvements
Patients are encouraged to maintain physical activity and long-term lifestyle changes to ensure optimal outcomes.
Results & Longevity
Patients can expect:
- Significant weight loss exceeding standard sleeve gastrectomy outcomes
- Improvement or resolution of type 2 diabetes, hypertension, and other metabolic disorders
- Enhanced hormonal regulation of appetite and blood sugar
- Long-term improvement in energy, mobility, and overall quality of life
Results depend on adherence to post-operative care, diet, and lifestyle modifications.
