Duodenal Switch


Duodenal Switch is an obesity surgery method that provides weight overruns that are both restrictive in the stomach and malabsorptive. The restrictive part of the surgery involves the removal of approximately 70-75% of the stomach and a large part of the duodenum, or twelve finger intestines. For this restriction, the left side of the patient’s stomach is removed first. As a result, the stomach becomes a thin and long tube. This part, which is applied in the surgery, is a procedure that can no longer be reversed. The most important part of the surgery is to reroute a long part of the small intestine to create two separate paths and a common channel. The shortest of these two ways is the small intestine that will take the stomach to the canal. The longer part of the intestine is the part where bile and other digestive enzymes mix with food and cause absorption. Briefly, the purpose of these regulations is to selectively limit fat absorption by reducing the time it takes for the body to absorb calories from food in the small intestine. After Duodenal Switch surgery, patients lose two-thirds of their excess weight within 2 years. This method is a heavier operation than other surgeries, but thanks to this method, more effective weight loss is observed.

After Duodanal Switch, you can feed with small and frequent meals. Because your new and small stomach cannot take large meals. Likewise, your stomach cannot tolerate large amounts of fat, alcohol or sugar. For this reason, if you want to survive this surgery with minimal complications, you will definitely need to reduce your fat intake, fast food, sugar-containing cakes, frozen foods, sweets, cookies and candies.

After Duodenal Switch surgery, you lose two-thirds of your excess weight, on average, within two years. Although this surgery is a more severe operation compared to other surgeries, a more effective weight loss is experienced compared to other surgeries.

After the surgery, the stomach is tubed and thus food intake is restricted, while absorption will decrease as the last 250 cm of the small intestine is used for food passage. In this way, you have the advantage of more effective weight loss. Since the valve at the stomach outlet will not deteriorate, there is no leakage of bile and, accordingly, gastric ulcer. Since this valve is protected, symptoms such as low blood pressure, fainting and vomiting due to the passage of food into the small intestine, namely Dumping Syndrome, will not be seen. As in bypass surgeries, a dysfunctional stomach part that cannot be reached is not left in the body. Duodenal Switch surgeries are known as one of the most effective methods for the treatment of morbid obesity and the control of diabetes. For those who gain weight in the long term after sleeve gastrectomy surgery, the transition to this surgery will be very simple.

As with all malabsorption procedures, electrolyte and vitamin deficiencies can also be seen in this surgery.
