Modified Duodenal Switch surgery, is showing no signs of slowing down, and continues to be performed at Medical Park Hospitals in Turkey.

In the USA, Modified Duodenal Switch surgery (shortening of the small intestine), which is mentioned as a new trend treatment of obesity and diabete, is performed at Antalya MedicalPark Hospital. Turkey Medicals member General Surgeon Prof. Dr. said the surgery was started to trend for better life to be made.

DT, a 50-year-old resident of Antalya, said that he got rid of obesity and diabetes, which he has been struggling with for 20 years, with the Duodenal Switch method performed for the first time at the Antalya Medical Park Hospital. DT, a father of three children, stated that he started to gain excessive weight after the age of 30, followed a serious diet program and dropped to 110 kgs when I reached 140 kgs.

Referring to the fact that he reached 150 kgs 2 months after quitting the diet, DT said, “The problem I had with obesity, which I met in my 30s, was negatively affecting my life. Two years ago, when I reached 195 kgs, I underwent surgery using the ‘Tube stomach’ method. I’ve lost 132 kgs in 2 years. But obesity and diabetes were continuing to affect my quality of life,” he said.

DT said that he had Duodenal Switch surgery at the Antalya Medical Park Hospital and that he is currently 125 kgs. DT said, “My doctors say that I will reach my ideal weight soon. I am very happy to have got rid of obesity and diabetes,” he said.


The first Modified Duodenal Switch surgery at the Antalya Medical Park Hospital was performed, Prof. Dr. who said that they did it by laparoscopic method gave the following information:

“Our patient has had tube stomach surgery before. After a while, we performed a Modified Duodenal Switch operation on the patient who started gaining weight again. In this method, the last part of the patient’s small intestine is placed in place of the aborted 12 finger  intestine. Thus, the patient gets rid of their excess weight at a serious rate. However, there is also a 95 percent solution to the sugar problem.”


Referring to the fact that the three-hour operation at the Antalya Medical Park Hospital is the second Modified Duodenal Switch surgery performed by laparoscopic method in Turkey, Assoc. Dr. who performed the operation for the first time in Turkey said, “After our patient DT, who came from Antalya, we performed the same surgery on 3 more patients at Altınbaş University Medical Park Bahcelievler, BAU Medical Park Goztepe, İstinye University Hospital in Bahceşehir Istanbul.

At the end of the Duodenal Switch operations, one of which was performed by laparoscopic method, the patients also stopped taking sugar medications.


Duodenal Switch surgery, which can only be performed by about 50 specialist surgeons all over the world, is characterized as a longer and more complicated operation compared to other stomach surgeries. By reducing the stomach with this method, food intake is reduced. Then the small intestine is divided and joined to the stomach, one end of which remains to form the alimentary canal. Food passing through the stomach completely bypasses the duodenum and the middle part of the small intestine and empties into the last part of the small intestine.

Meanwhile, the fluid and bile containing pancreatic enzymes are controlled by pylor at the gastric outlet and connected to the alimentary canal by a leg called the biliopancreatic canal. Along this channel, called the common channel, the absorption of nutrients, vitamins and minerals takes place.”

With this method, overweight patients lose weight better than clamp and gastric bypass methods, in addition to weight loss, it is stated that they also get rid of diabetes disease at a high rate.


Prof. Dr. said that Duodenal Switch surgery is more preferred in the United States, and it is not performed in large numbers in the United States because it is a very complex, difficult and experience-requiring surgery.

Emphasizing that the most effective method of obesity among surgical methods is Duodenal Switch surgery, Prof. Doctor said, “The patient becomes weaker during tube stomach and gastric bypass in Turkey, which are previous surgical interventions related to obesity, but he starts to gain weight again after 5 years. But Duodenal Switch is a surgical method that has been determined by clinical trials that the patient has not gained weight for at least 20 years,” he said.

Prof. Dr. pointed out that with this operation, obesity-related diabetes patients have also regained their health.
