Hello there. I am Operator Doctor Türker Karabuğa. I have been performing obesity and diabetes surgery for about fifteen years. In this video, I would like to give some information about sleeve gastrectomy. Sleeve gastrectomy is the process of removing approximately eighty percent of the stomach together with the part that secretes appetite hormone and removing it by closed method using special devices. This procedure takes approximately forty-five to fifty minutes. After this procedure, since there is a serious loss in the patient's appetite and a serious loss in the volume of the stomach, the patient reaches his ideal weight in about a year. During this process, since the patients are under constant follow-up with us, we frequently make the necessary interventions and necessary controls. Gastric sleeve gastrectomy is one of the most widely used, most reliable, least risky and most applied methods in the world.
