If a stomach-OP using a bypass technique is carried out in Turkey, a part of the digestive tract is bypassed by the surgical procedure. This results in reduced food intake, which supports the weight-reduction in two ways. In Parallel, however, it also limits the absorption of nutrients, wherefore often a danger of deficiencies occurs, and the patient has to take lifelong vitamins (e.g., vitamin B12), trace elements as well as proteins.

The Gastric Bypass

The gastric bypass is the most complicated stomach OP within the bariatric surgery, in which the capacity is reduced to about 15-20 ml. The rest of the stomach is then sewn together with a loop of the small intestine (= bypass). In Turkey, the gastric bypass operation is performed under general anesthesia, and the patients will be stationed in the intensive care unit for controlling.

At the beginning of the gastric surgery, the surgeon reduces the stomach (to 15-20 mm) and sutures it with a low-lying part of the small intestine, so that the twelve-finger intestine is excluded from digestion. Thus, food and digestive juices first intermingle in the middle small intestine, which results in a lower calorie intake.

Gastric Bypass surgery in Turkey

The Roux-Y-gastric Bypass

The roux-x-gastric bypass is one of the most commonly performed gastric-OPs worldwide and helps to reduce – within the first two years after the laparoscopic surgery – up to 70 % of the body weight. Again, your surgeon in Turkey separates the pyloric part from the stomach, in order to form an about 20 ml large gastric pouch. The advantage of this gastric surgical method is, that the rest of the stomach remains in the patient, so theoretically – even if only rarely – a complete deconstruction of the original stomach would be possible.

The Omega (Mini) Bypass

In the case of the omega bypass or mini bypass, the surgeon does not sever the small intestine, but connects it to the gastric bag about two meters after the duodenum. In particular, this bypass variant has found a general application within the obesity surgery, and is thus one of the most commonly used variant in Turkey.

The Transit Bipartition (according to Santoro)

A transit bipartition according to Santoro is a new gastric bypass technique which is especially used when obesity is associated with diabetes (type-2). Transit bipartition stands for ‘intestine division’ – i.e., besides the direct diversion of food through the small intestine, it can also enter the intestine via the normal way. This not only activates the natural hormonal mechanisms that lead to an early satiety, a poor absorption of nutrients is prevented at the same time (malabsorption).

The Biliopancreatic Diversion

In the biliopancreatic diversion (BPD), the surgeon reduces the stomach to a size of approximately 20-30 cm. Here, the rest of the stomach is sutured with a loop of the small intestine, so that the duodenum is bypassed. As a result of this gastric surgery, in which only about 7.5-10 cm of small intestine remain, the intake of fats and carbohydrates is greatly reduced and thus the weight loss is promoted.

The Duodenal Switch

In the case of the BPD with duodenal switch (DS), the specialist located in Turkey removes the large portion of the stomach (corpus and fundus) and forms a stomach-tube. Here, the duodenum is transected and the stomach is sutured to the small intestine (approximately 100 cm in front of the colon), too. Advantages of this method are both the preservation of the stomach gatekeeper as well as the sphincter muscle at the stomach exit. In this way, the so-called “dumping syndrome” is prevented: If sugar-containing food too quickly reaches the small intestine and thus into the blood, the patient can experience hypoglycemia, which can lead, for example, to nausea and sweating.
