Biliopancreatic Diversion with Duodenal Switch (BPD) is a bariatric surgery that is both restrictive and malabsorptive, which means that it reduces a patient’s capacity for food and also changes the way that calories and nutrients are absorbed by the body. This surgery has been shown to be effective for patients with severe morbid obesity.*
How Does Duodenal Switch Work?
In most cases, the Duodenal Switch procedure can be done with laparoscopic technique to minimize scarring and improve recovery time. A portion of the stomach is removed and this creates a smaller capacity for food, reducing the amount that a patient can eat in one sitting. A portion of the small intestine, called the duodenum, is divided and redirected, circumventing pancreatic and bile drainage. This step changes the way the body digests food so that fewer calories are absorbed.
The Benefits of Duodenal Switch*
- Biliopancreatic Diversion with Duodenal Switch resolves 99.1% of hyperlipidemia 3
- Studies show excellent results in reversal rates of other obesity related diseases such as Type 2 diabetes, sleep apnea, hypertension, high cholesterol and high blood pressure 4
- Patients typically lose over 50% of excess weight within one year of surgery. 5
Loop Duodenal Switch
If you are interested in losing weight using the Duodenal Switch (DS), you may be a candidate for the Loop Duodenal Switch (SADI-S). The Loop Duodenal Switch is a variation of the Duodenal Switch procedure which may have favorable outcomes for some patients. The Loop Duodenal Switch surgery is both restrictive and malabsorptive, meaning the size of the stomach is reduced and there is less absorption of calories. Weight loss is achieved by diminished appetite and capacity for food as well as reduced calorie absorption due to a reduction of the small intestine. In the Loop Duodenal Switch procedure, the small intestine retains more of its length in order to maximize the absorption of nutrients.
Benefits the Loop Duodenal Switch*
- Increased nutrient absorption compared with traditional Duodenal Switch
- Studies show more than 90 percent of the patients experienced complete remission of Type 2 diabetes 1
- Studies show hypertension was controlled in 98 percent of the patients and remission rate was 58 percent 2
Am I a Candidate for Duodenal Switch?*
Duodenal Switch is a surgical option for patients with severe morbid obesity. As with any surgery, there are risks and medical factors to consider. However, the effectiveness of Duodenal Switch to improve critical obesity related conditions is an important advantage to patients suffering with obesity.* Patients report a vast improvement to their quality of life after BPD.* As with all weight loss surgeries, patients must be prepared to follow all dietary instructions and devote energy to living a healthier lifestyle.
