Biliopancreatic Duodenal Switch Gastric Bypass is a well-studied but rather complex bariatric technique for patients with high degrees of obesity.
Weight loss is provided by a combination of restrictive and malabsorptive methods – during the operation, the volume of the stomach is reduced and the small intestine is reconstructed, achieving a decrease in the absorption of nutrients.The most important part of the operation is rerouting the long part of the small intestine to create two separate paths and a common canal.
The shortest of these two pathways created is the small intestine, which will take whatever comes from the stomach into the canal. The longer part of the intestine is where bile and other digestive enzymes mix with food and cause absorption.
In short, the goal of these rules 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 more difficult operation than other operations, but thanks to this method, more effective weight loss is observed.
Patient’s profile:
This operation is indicated for people with a high BMI, from 45 kg / m2 and above. This is a very strong operation that combines two mechanisms of weight loss due to vertical gastroplasty, the stomach is reduced and food absorption is reduced due to duodenal switching of the intestine.
Laparoscopic technique allows patients to quickly rehabilitate even after such a complex intervention.
In some cases, the operation is performed in two stages: vertical gastrectomy – a narrow tube with a volume of 80-120 ml is formed from the stomach and after a while biliopancreatic shunting – reconstruction of the intestine to limit the absorption of nutrients.
During biliopancreatic shunting, cholecystectomy can be performed simultaneously.
Expected result of Biliopancreatic Bypass surgery:
The average result of losing weight after Duodenal Switch is the loss of about 80% of excess weight and stable weight retention for many years, getting rid of type 2 diabetes, sleep apnea, and hypertension.
After Duodenal Switch, you can feed yourself small, frequent meals. Because your new and small stomach cannot take big meals. Similarly, your stomach cannot tolerate large amounts of fat, alcohol, or sugar.
For this reason, if you want to survive this operation with minimal complications, you should definitely cut down on fat, fast food, sugary cakes, frozen foods, sweets, cookies, and candies.
After Duodenal Switch surgery, you lose an average of two-thirds of your excess weight within two years.
Although this surgery is more severe than other surgeries, there is more effective weight loss compared to other surgeries.
After surgery, the stomach is tightened so food intake is limited and absorption is reduced as the last 250 cm of the small intestine is used to pass food. Thus, you get the benefit of more effective weight loss. Since the valve at the outlet of the stomach does not deteriorate, there is no leakage of bile and, accordingly, a stomach ulcer. Since this valve is protected, symptoms such as low blood pressure, fainting and vomiting due to food entering the small intestine, namely dumping syndrome, will not be visible. As with bypass surgery, there is no unreachable part of the stomach in the body that does not work. Duodenal Switch surgery is known as one of the most effective treatments for morbid obesity and diabetes control. For those who gain weight for a long time after sleeve gastrectomy surgery, the transition to this operation will be very simple.
As with all malabsorption procedures, electrolyte and vitamin deficiencies can also occur with this operation.
