Sleeve gastrectomy in Korea: what should you know?

Why it may be considered

Sleeve gastrectomy does not bypass the small intestine, and food continues through the normal gastrointestinal route. It is commonly used as a bariatric and metabolic procedure in appropriately selected patients.

What must be reviewed before treatment

A specialist review may include:

• BMI and weight history;
• type 2 diabetes and other obesity-related conditions;
• previous weight-loss treatment;
• current medication, including GLP-1-based medication;
• laboratory and metabolic tests;
• reflux symptoms and gastrointestinal history;
• upper gastrointestinal endoscopy where indicated;
• anaesthesia risk;
• nutritional status;
• previous abdominal surgery.

Reflux and gastric evaluation

Sleeve gastrectomy may not be the best option for every patient with significant reflux or certain oesophageal findings. Pre-operative endoscopy can therefore be important in deciding whether sleeve gastrectomy or another procedure should be discussed.

Potential benefits

In eligible patients, sleeve gastrectomy can produce substantial weight loss and may improve obesity-related metabolic conditions, including type 2 diabetes. Individual results vary.

Risks and long-term considerations

Possible risks include:

• bleeding;
• infection;
• staple-line leak;
• blood clots;
• anaesthesia-related complications;
• reflux;
• nutritional deficiency;
• insufficient weight loss or later weight regain.

Recovery and follow-up

Recovery usually includes a staged progression from liquids to soft foods and then to a long-term eating pattern. Patients commonly require:

• protein and nutrition guidance;
• vitamin and mineral supplementation;
• scheduled blood testing;
• review of medications;
• long-term follow-up after returning home.

Questions to ask

• Is sleeve gastrectomy suitable for my medical profile?
• Does reflux or an endoscopic finding affect the procedure choice?
• What pre-operative tests will I need?
• How will my nutrition be monitored?
• What follow-up can be continued in my home country?
• How long should I stay in Korea before flying home?
