What is Sleeve Gastrectomy?

Laparoscopic Sleeve Gastrectomy is an obesity surgery that removes about 80% of the stomach and restricting food intake. While approximately 65% of metabolic and obesity surgeries are performed all over the world, in our country, this rate reaches 95% because a very large proportion of surgeons dealing with obesity prefer only laparoscopic sleeve gastrectomy.

How Is Sleeve Gastrectomy Performed?

A large portion of the stomach is removed and left behind a banana-shaped narrow gastric “tube” or “sleeve”. The volume of this remaining stomach is around 120-150 cc.

After sleeve gastrectomy surgery, the person is unable to eat large amounts of food as they used to and feels quickly full. Because fewer calories are taken, the signals and hormones between the stomach and brain change and the person becomes less hungry.

With the removal of the fundus region of the stomach, the hormone called “Ghrelin”, known as the hunger hormone secreted from this region, decreases and makes the person less hungry. Something known as false needs to be corrected, Ghrelin is secreted not only from the stomach but also from the instentine and pancreas.

Since it’s observed that weight loss improves in all systems including metabolic syndrome, people express themselves healthier and feel better.

Obesity Surgery in Turkey

Almost a third of the world’s population is obese. This problem does not pass either rich or poor. The World Health Organization (WHO) estimates the problem of overweight and obesity as a global epidemic. Obesity directly affects the life expectancy of a person, and for the worse. In addition to obvious health problems, being overweight is often the cause of condemnation in society. At the same time, advertising magic diet pills and popular shows sometimes form an unreasonably light attitude to the problem. People put off solving the problem until later, which ultimately can lead to critical body weight and exacerbation of disease. Conservative methods of treating obesity have a lasting effect in only 5% of cases. As a rule, when discontinuing medication or returning to a normal lifestyle and diet, patients again gain weight, sometimes exceeding the initial one. Obesity surgery is recommended if there is no effect of classical therapy.

About Sleeve Gastrectomy Operation

It is known as “Stomach Reduction” or “Tube Stomach”. With this operation, it is aimed to reduce the volume of the stomach to approximately 60-100 cc and to feel full by taking a reasonable amount of food.

A certain part of the stomach is surgically removed and left with a tube section (about the size of a banana). In addition, the hunger hormone secreting part of the stomach is removed, the patient is prevented from feeling extreme hunger. With this operation, only the amount of food taken is limited. Since the absorption of foods continues in the same way, the patient does not need to take vitamin or mineral supplements from the outside.

How Is Surgery Performed?

Sleeve gastrectomy surgery is performed by laparoscopic method. The surgery is performed with 5-6 small incisions according to the weight of the patient. General anesthesia is applied to the patient during the surgery.


Approximately 6-8 hours after surgery, patients begin to be able to walk. 24 hours after the operation, the leakage test (Metinel liquid) is done and the X-ray is taken with medication after 48 hours. After checking the test results, patients can easily feel full by taking small volumes of food. After a while, this feeling of full turns into a normalisation of appetite, food intake decreases and it is possible to get rid of 80-90% of the excess weight within a few years following surgery.
