Gastric Sleeve

Which is called “Sleeve Gastrectomy” in the medical language, Gastric Sleeve Surgery; Generally known as stomach reduction surgery, it is one of the most popular surgical procedures performed worldwide. The sleeve gastrectomy, which was first applied as a part of the Duedonal Switch surgery in 1988, was performed with the open method, exactly 11 years later, with another first in the medical world. 

The real breakthrough in sleeve gastrectomy surgery was realized when it was started to be applied with the laparoscopic surgery method. Because, thanks to this method, it has become a surgical procedure that leaves less scars, and the duration of hospitalization after the operation has decreased.

How is Gastric Sleeve Surgery Performed?

Gastric sleeve surgery is performed by laparoscopic method. Laparoscopic surgery is a closed surgical technique. As in open surgeries, 10-15 cm incisions are not opened. Instead, a few holes of 0.5 cm in average are opened and the camera and treatment tools are sent to the abdomen through these holes.

In the laparoscopic method, this means that in the closed sleeve gastrectomy surgery, the stomach is first transformed into a thin long tube. Then, an average of 80% of the stomach is removed after the cutting process. In this way, your stomach’s need for food becomes much more limited than before, and your appetite decreases at the same rate. In addition, the body’s insulin resistance is broken.

During the procedure, there is no disruption in the continuity of the digestive system by protecting the inlet and outlet parts of the stomach. Therefore, the risk of stomach reduction surgery is extremely low.
