There are several types of gastric bypass surgery. Not every surgical procedure is suitable for each patient, which is why accurate examinations are necessary to find the right variant. Which types of gastric bypass exist and what they look like, you will find below.
The gastric bypass
It is the most established and widely used method in bariatric surgery, gastric bypass. The goal is, as with all other variants, that the patient loses significant weight. The stomach is massively reduced during the operation. Patients can therefore eat much less food. However, unlike a stomach operation, the remainder of the stomach remains in the body and can continue to produce digestive juices. The small intestine is redirected within the operation in such a way that digestive juices and food can only be mixed together with delay in the small intestine. Because of this fact, portions of ingested calories cannot be digested as by sugar and fat. These simply leave the body of the patient with the bowel movement.
The Omega Loop Bypass
The omega loop bypass is also referred to as a so-called mini-bypass and also targets the effect of a reduction of the stomach and weight loss. In this variant, there is a clear advantage in the comparatively short operation time. But the risk is minimized, as seams are saved. Critically, however, the risk of increased risk of ulceration is. However, there are no long-term studies, so this assumption could not be proven yet. With an Omega Loop Bypass, it is also not necessary that the small intestine is severed, as within the operation of a slightly larger gastric pouch is created.
The classic gastric band
Using small cuts in the abdominal wall, which are only a few centimetres in size, a band is placed around the upper area of the stomach and placed under the skin. Without additional surgery, the gastric band can then be adjusted via the reservoir from the outside. The band separates the forestomach from the remaining part of the stomach and thus achieves a restrictive effect. The intake of food is restricted and the feeling of satiety occurs much earlier due to the elongation of the forestomach. An advantage here too is the fact that no irreversible changes have to be made to the digestive tract. Important for you as a patient, the procedure can be undone at any time.
The gastric pacemaker
The gastric pacemaker is implanted within a minimally invasive surgical operation. The so-called ability system has the goal that the activity and eating habits of the patient are recorded. Following this, an adapted eating behaviour of the patient should bring about a permanent weight reduction. The gastric pacemaker is suitable for people with a BMI between 35 and 55. This method also does not interfere with the digestive tract and its anatomy. If the gastric pacemaker is activated, then the food intake in liquid and solid form are registered and stored. In addition, the gastric pacemaker sends pulses to the stomach, which should provide a feeling of fullness, even before it has come to a real filling of the stomach.
