Laparoscopic sleeve gastrectomy is the most commonly used method in the treatment of obesity. The operation allows the stomach to take the shape of a tubular tube extending through the small curvature. The avarage volüme of the stomach is about 150 – 200 cc.
There are 2 weight loss mechanism in this surgery; restrictive and hormonal effect. Feeling of satiety with little food after vertically collapsing the stomach is a restrictive effect. The hormonal effect is the loss of appetite with reduced release of the ghrelin hormone produced by the cells in the fundus, which is the upper part of the stomach.
After the operation, the patients lose about 65-70% of their excess weight in about 12 months. The patient can increase this weight loss rate up to 100% with other supportive factors such as sports. One of the greatest advantages of operation of the tube gastric (sleeve gastrectomy) is that there is no problem in the intake of vitamins and minerals since there is no operation that affects the absorption.
Patients only receive temporary supports such as iron during certain periods (first fluid feeding period). As with all obesity surgeons, nutrition gradually changes in this procedure and should be accompanied by a nutritional counselor during adaptation. Following tube stomach operation, 20% of back weight gain can occur in patients with adaptation disorders in nutritional form being the biggest factor.
