Sleeve Gastrectomy is the surgical removal of the part called the fundus that constitutes 80% of the stomach. By removing the fundus section of the stomach, the secretion of the hunger hormone, which in medicine is called the ghrelin hormone, decreases. The ghrelin hormone is a peptide protein secreted from the fundus. It is also an important stimulus for the feeling of hunger in the brain. As sleeve gastrectomy involves the removal of the fundus part of the stomach, less amount of hormone is secreted, and accordingly, the person feels full. In this way, it can significantly contribute to weight loss by reducing appetite.

Since sleeve gastrectomy has fewer postoperative complications and can be converted to malabsorptive surgery when needed, it is practiced more commonly with every passing day all over the world.

Sleeve gastrectomy is performed by laparoscopic (closed surgery) method under general anesthesia, by making 5-6 half-centimeter incisions. During the operation, a tube is inserted into the stomach. With the help of a stapler, a large part of the stomach is removed through a hole of 2 cm, under the guidance of the inserted tube. At the end of the operation, the suture line is checked for bleeding. In addition, the stomach is inflated with special dyes to check for leaks at the suture line. After the control procedures, the tube placed in the stomach is removed and the procedure is ended by placing a drainage system in the abdomen.

Sleeve gastrectomy It is an irreversible surgical procedure. However, it can also be converted to a bypass surgery if necessary.
