General Features
It is both a restrictive and a calorie-reducing operation.
It is the most commonly used bariatric surgery method in the United States and many European countries.
Rny gastric Bypass surgery
A patient whose stomach has been reduced by RNY gastric Bypass surgery can consume smaller portions, but with these small portions, they can eat without feeling hungry.
Rny Gastric Bypass also reduces the absorption rate of consumed foods.
After surgery, the level of the appetite hormone, called the ghrelin hormone, drops, and the patient’s appetite is clearly reduced.
Because excessive/rapid consumption of high-calorie foods (especially carbohydrate-containing foods) after surgery can disturb patients, patients make their eating/drinking habits healthier.
(A tendency is exhibited by patients to avoid sweet and fatty foods).
Rny gastric Bypass surgery
1. In the first way, the initial part of the esophagus, stomach and small intestine is located.
2. In rny gastric Bypass surgery, in the upper part of the stomach, with the help of staples, the stomach is divided into one small large part, so that the patient can eat smaller portions in quantity (restrictive effect).
3. The small intestine is divided and (A) ready for connection to the reduced stomach.
4. The small intestine (A) is pulled up from where it divides and connected to the reduced stomach by circular staples.
At a point further than the newly created small gastrointestinal connection point, the intestine (B) from the remaining stomach is reconnected to the main line. In this way, the enzymes and liquids produced by the remaining stomach(B) combine with the food taken and continue on their normal path, since the necessary vitamins continue to be taken by the body, there is no deficiency.
One of the biggest advantages of this operation is that the food taken and the remaining (non-food) fluids produced by the stomach (enzymes, bile and pancreatic fluids) merge at an advanced point, not immediately. In this way, fat and sugar absorption, that is, calorie absorption, is reduced. (absorption reducing effect)
In addition, by the fact that the transition point of the reduced stomach to the intestine is smaller than normal, the slow emptying of the stomach is achieved and a longer feeling of satiety is created in patients.
