Treatment Overview
Revisional Sleeve Gastrectomy in Korea is a specialized bariatric surgery designed for patients who have previously undergone weight loss surgery but require a revision due to insufficient weight loss, weight regain, or complications from the original procedure. This surgery involves modifying or redoing the initial sleeve gastrectomy to optimize stomach size and restore effective weight control.
Korean hospitals perform revisional procedures using advanced laparoscopic or robotic-assisted techniques, combining surgical precision with comprehensive pre- and post-operative care. This ensures safe, effective outcomes for both domestic and international patients.
Purpose & Benefits
The main purpose of revisional sleeve gastrectomy is to correct issues from prior bariatric surgery and achieve sustainable weight loss and metabolic improvement.
Key benefits include:
- Correction of anatomical or functional issues from previous surgery
- Enhanced and sustained weight loss after revision
- Improvement or resolution of obesity-related comorbidities such as type 2 diabetes, hypertension, and sleep apnea
- Minimally invasive surgery with reduced pain and faster recovery
- Hormonal and metabolic improvements for appetite control and satiety
- Improved quality of life and overall health outcomes
Ideal Candidates
This procedure is suitable for patients who:
- Experienced insufficient weight loss or weight regain after initial sleeve gastrectomy or other bariatric procedures
- Have complications from previous surgery, such as sleeve dilation or reflux
- Are physically fit for revisional surgery and committed to lifestyle modifications
- Seek to improve metabolic health and achieve sustainable weight loss
- Require expert care for complex surgical scenarios
Korean hospitals provide multidisciplinary support, making it ideal for international patients seeking advanced revisional bariatric surgery.
Possible Risks & Complications
Revisional bariatric surgery carries higher risks than primary procedures. Potential complications include:
- Bleeding or infection
- Staple line leaks or perforation
- Nutritional deficiencies if dietary guidelines are not followed
- Gastroesophageal reflux or gastrointestinal obstruction
- Rare complications such as blood clots or anesthesia-related issues
Korean bariatric centers perform thorough pre-operative evaluations, imaging, and nutritional counseling to minimize risks and ensure safety.
Techniques & Technology Used
Korean hospitals employ advanced laparoscopic and robotic-assisted techniques for revisional sleeve gastrectomy. Key features include:
- High-definition laparoscopic cameras for precise visualization
- Advanced stapling devices for safe revision of the stomach sleeve
- Pre- and post-operative nutritional assessment
- Monitoring of metabolic health, weight progress, and post-operative complications
The process includes meticulous pre-operative planning to assess prior surgical outcomes and identify potential risks.
Treatment Process in Korea
- Consultation & Assessment: Review of previous surgical history, BMI, and comorbidities.
- Pre-Operative Planning: Imaging, lab tests, and nutritional counseling to prepare for revision.
- Surgery: Laparoscopic or robotic-assisted revisional sleeve gastrectomy, typically lasting 2–3 hours depending on complexity.
- Hospital Stay: Usually 3–5 days for monitoring, pain management, and early mobilization.
- Postoperative Care: Follow-up visits for weight, nutritional status, metabolic health, and lifestyle guidance. International patients receive travel and care coordination support.
Recovery & After-Care
Recovery involves:
- Mild post-operative discomfort managed with medications
- Gradual return to daily activities over 1–2 weeks
- Adherence to post-operative diet, supplementation, and exercise recommendations
- Regular follow-ups to monitor weight, nutrient levels, and overall health
Structured follow-up ensures early detection of complications and promotes long-term success.
Results & Longevity
Patients can expect:
- Significant weight loss after revision, often restoring or exceeding initial results
- Improvement or resolution of obesity-related comorbidities
- Enhanced energy, mobility, and overall quality of life
- Long-term maintenance of weight and metabolic health through adherence to dietary and lifestyle guidelines
Outcomes depend on individual health, surgical complexity, and compliance with post-operative care.
