Treatment Overview
Roux‑en‑Y Omega Loop Gastric Bypass (RYOLGB) is an advanced bariatric surgery designed to achieve significant weight loss and improve metabolic health. The procedure involves creating a small stomach pouch and rerouting the small intestine in a single loop (Omega Loop), reducing calorie absorption and triggering hormonal changes that improve insulin sensitivity and appetite control. Korea is recognized for performing RYOLGB with advanced laparoscopic and robotic-assisted techniques, offering precise surgery and comprehensive care for international patients.
Purpose & Benefits
RYOLGB offers multiple benefits for patients:
- Significant and sustained weight loss.
- Improvement or remission of type 2 diabetes and insulin resistance.
- Reduction of obesity-related conditions such as hypertension, dyslipidemia, and sleep apnea.
- Faster recovery and shorter hospital stay compared to traditional Roux‑en‑Y.
- Improved metabolic health through hormonal regulation and appetite control.
Ideal Candidates
RYOLGB is suitable for:
- Adults with BMI ≥ 35.
- Patients with BMI 30–34.9 who have obesity-related metabolic disorders.
- Individuals with type 2 diabetes or metabolic syndrome seeking effective surgical intervention.
- Adults aged 18–65 committed to long-term lifestyle changes, dietary compliance, and follow-up care.
Possible Risks & Complications
While generally safe, potential risks include:
- Surgical complications such as bleeding, infection, or anesthesia reactions.
- Nutritional deficiencies (vitamins B12, D, calcium, iron) if dietary guidance is not followed.
- Dumping syndrome or gastrointestinal disturbances.
- Rare complications such as leaks at the surgical site, bowel obstruction, or ulcers.
Korean hospitals minimize risks with meticulous pre-operative evaluation, minimally invasive techniques, and structured post-operative monitoring.
Techniques & Technology Used
Korean hospitals use advanced methods to ensure optimal outcomes:
- Laparoscopic RYOLGB: Minimally invasive surgery reduces recovery time and scarring.
- Robotic-Assisted Surgery (optional): Provides enhanced precision for complex cases.
- Single-Loop (Omega) Technique: Simplifies the surgery while maintaining effective weight loss and metabolic results.
- Post-Operative Monitoring: Tracks weight loss, nutritional intake, and metabolic improvements.
- Multidisciplinary Care: Surgeons, dietitians, endocrinologists, and psychologists collaborate for comprehensive support.
Treatment Process in Korea
- Consultation: Assessment of BMI, metabolic health, and comorbidities.
- Pre-Operative Testing: Blood tests, imaging, nutritional and hormonal evaluation.
- Surgery: Performed under general anesthesia, typically lasting 2–3 hours.
- Hospital Stay: 2–3 days with multidisciplinary monitoring.
- Post-Operative Care: Includes dietary guidance, exercise planning, metabolic monitoring, and regular follow-ups.
Recovery & After-Care
- Immediate Post-Surgery: Early ambulation, hydration, and liquid diet.
- Weeks 2–4: Gradual transition from liquid to soft foods, then solid foods under dietitian supervision.
- Nutritional Supplements: Essential vitamins and minerals to prevent deficiencies.
- Lifestyle Support: Balanced diet, portion control, exercise, and behavioral counseling.
- Regular Follow-Ups: Ensure proper weight loss, metabolic improvements, and nutritional balance.
Results & Longevity
- Patients typically achieve 60–80% excess weight loss within 12–18 months.
- Significant improvement or remission of type 2 diabetes, hypertension, and dyslipidemia.
- Lifelong adherence to diet, supplements, and follow-ups ensures sustained outcomes.
- High patient satisfaction due to simplified procedure, fast recovery, and comprehensive care.
