Gastric Sleeve Surgery

What is Gastric Sleeve Surgery?

Gastric sleeve surgery, also known as "Sleeve Gastrectomy"; It is commonly known as stomach reduction surgery, however, it is one of the most popular surgical procedures. Gastric sleeve surgery has become a stand-alone surgical procedure since the year it became popular. Over time, with the advancement of technology, it has become a surgical procedure that leaves less scars, and the postoperative hospital stay has decreased. With this situation, there has been a great increase in the popularity of sleeve gastrectomy surgery.

How is Gastric Sleeve Surgery Applied?

General anesthesia is administered to patients before surgery. The operation varies between 45-90 minutes on average. Gastric sleeve surgery is performed by forming a tube from the stomach to the esophagus through a small hole in the stomach area. During this procedure, a large part of the stomach is removed. As the stomach shrinks, food intake decreases. Since the fundus, the region where the appetite hormone is secreted in the stomach, is removed, the feeling of appetite is greatly reduced after the surgery. With the removal of the reservoir area, the passage of food into the intestine is faster than normal, and thus the satiety hormone is secreted early. Thus, patients experience the feeling of fullness soon after eating.

For Which Patients Is Gastric Sleeve Surgery Suitable?

Gastric sleeve surgery is the method used for obese patients today. Although it is not as effective as the classical metabolic surgery or gastric bypass surgery group, positive results are also obtained in correcting Type 2 diabetes. Gastric sleeve surgery is not recommended for obese patients with uncontrolled diabetes or severe reflux problems. There is an opportunity to convert sleeve gastrectomy surgery to other surgical techniques in the future. It is much easier to convert sleeve gastrectomy to metabolic techniques such as gastric bypass or Duodenal Switch with a second surgical procedure.

Post Gastric Sleeve Surgery Process

After gastric sleeve surgery, rapid weight loss is experienced, especially during the first 3 months. Patients who see that they lose weight quickly experience the desire to stop the exercises. If the exercise and healthy nutrition recommendations are not taken into account, the rate of weight loss will decrease in the future, and the efficiency obtained from the surgery will decrease.


Postoperative weight loss varies from person to person. In this regard, the factors around the person are also extremely important. Patients who eat healthy and do regular sports get rid of 80% of their excess weight in about 1-2 years.



Possible complications of Gastric Sleeve Surgery include bleeding, organ injury, embolism and anesthesia-related complications, as in all surgical procedures.

Complications that will occur in the surgery are the leakage from the cut and sutured part of the stomach. During the operation, the stomach is inflated with a special blue dyed serum, and the suture line is checked, and the tightness test is performed. Thus, the risk is minimized. Sometimes a second surgery or non-surgical interventions may be required.
