Duodenal Switch is both a restrictive and malabsorptive bariatric surgery procedure intended for weight loss. The restrictive part of the operation involves the removal of approximately 70-75% of the stomach and a large proportion of the duodenum. For this restriction, first the left side of the patient’s stomach is removed. As a result, the stomach turns into a thin, long sleeve. This is an irrevocable step of the procedure. The most important step of the procedure involves the rerouting of a long section of the small intestine, in such a way as to create two separate paths and a joint channel. The shorter one of these two paths created is the portion of the small intestine that will deliver things coming from the stomach to the channel. The longer portion of the small intestine is the part that leads to greater absorption, where bile and other digestive enzymes get mix with foods. In short, these regulations are intended to selectively limit the fat absorption, by shortening the time of the body’s caloric intake from the foods in the small intestine. Within 2 years after Duodenal Switch surgery, patients lose two-thirds of their excess weight. This is a surgical procedure more invasive than other bariatric procedures. However, more effective weight losses are observed thanks to this procedure.
What can I eat after Duodenal Switch?
You can eat small frequent meals after Duodanal Switch. This is because your new and small stomach cannot intake big meals. Similarly, your stomach cannot tolerate large amounts of fat, alcohol or sugar. Therefore, if you want to get through the surgery with minimal complications, you will need to definitely reduce your fat intake and consume less fast foods, sugar-containing cakes, frozen foods, desserts, cookies and candies.
How much weight will I be able lose after Duodenal Switch?
Within two years (on average) after Duodenal Switch surgery, you lose two-thirds of your excess weight. This is a surgical procedure more invasive than other bariatric procedures. However, it provides more effective weight loss than other procedures.
What are the advantages of Duodenal Switch surgery?
Since the stomach is given a tubular shape, food intake becomes limited after surgery; and since the last 250 cm of the small intestine is used for food passage, absorption becomes limited as well. In this way, you have the advantage of achieving more effective weight loss. Since the valve at the exit of the stomach will be kept intact, bile leakage and the associated gastric ulcer will not be experienced. Because this valve is preserved, signs such as low blood pressure, fainting and vomiting due to the passage of foods into the small intestine, i.e. Damping Syndrome will not be seen. The inaccessible nonfunctional portion of the stomach is not left in the body, as in other bypass operations. Duodenal Switch operations are known to be one of the most effective procedures for the treatment of morbid obesity and control of diabetes. Switching to this procedure will be very simple for those who regain weight over a long term after sleeve gastrectomy.
Does Duodenal Switch surgery have any disadvantage? If so, what are they?
As in all malabsorptive procedures, electrolyte and vitamin deficiencies can also be seen in this surgical procedure.
