What Is Gastric Sleeve Surgery at Acibadem Hospital?

A gastric sleeve, or sleeve gastrectomy, is a powerful and safe bariatric surgery. The procedure works in two ways. First, your surgeon laparoscopically (using “keyhole” incisions) removes about 75-80% of your stomach. This leaves a small, banana-shaped “sleeve,” which restricts the amount of food you can eat, helping you feel full much faster. Second, the removed portion of the stomach is responsible for producing most of the body’s “ghrelin,” the hunger hormone. By removing it, the surgery dramatically reduces your appetite, making it easier to adapt to your new lifestyle.

Having your gastric sleeve at Acibadem means this procedure is performed in one of the most advanced medical environments in the world. Acibadem Health Group is JCI-accredited, which is the “gold standard” for hospital safety and quality, identical to top hospitals in the United States. This means your surgery is supported by:

  • Advanced Technology: State-of-the-art operating theatres equipped for advanced laparoscopic and robotic surgery.
  • Expert Support Staff: Highly trained anaesthesiologists, bariatric nurses, and nutritionists who are all part of a multi-disciplinary team.
  • Strict Safety Protocols: Proven, internationally-audited protocols for everything from infection control to post-operative monitoring.

As a surgeon, Prof. Dr. Karatepe explains that the hospital’s infrastructure is a critical tool for safety. Performing this advanced procedure in a hospital like Acibadem ensures every aspect of your care, from your pre-op tests to your private recovery room, meets the highest possible standard. It is the ideal environment for a safe and smooth gastric sleeve recovery.
