Biliopancreatic Diversion with Duodenal Switch (BPD), commonly known as duodenal switch, is a dual-approach bariatric surgery that can be effective for patients with severe obesity.
What is a Duodenal Switch?
Duodenal switch surgery, or biliopancreatic diversion with duodenal switch (BPD/DS), is a two-part bariatric surgery. This procedure helps patients lose weight through two mechanisms: it is restrictive in that it reduces the size of the stomach, and it is malabsorptive in that it reduces the calories and nutrients the body can absorb. Duodenal switch surgery also impacts hunger hormones, so patients feel less hungry after the procedure.1
Benefits of Duodenal Switch
Resolution of Type 2 Diabetes
Up to 98% of duodenal switch patients see a resolution of Type 2 Diabetes.2
Improved Sleep Apnea
Up to 90% of duodenal switch patients are able to discontinue using their CPAP machine.3
Improved High Cholesterol and High Blood Pressure
Following duodenal switch surgery, more than 70% of patients saw an improvement in high cholesterol, and nearly 79% of patients saw a resolution or improvement in high blood pressure.4
Duodenal Switch Surgery: What to Expect
The Duodenal Switch Procedure
Duodenal switch surgery is performed under general anesthesia. This is a two-part procedure.
In the first stage of duodenal switch surgery, a gastric sleeve is created when 80% of the stomach is removed and creates a narrow sleeve from the remaining part of the stomach.
In the second stage of duodenal switch surgery, the first part of the small intestine (the duodenum) is rerouted, so that food bypasses much of the digestive tract and empties directly into the end of the small intestine.
Duodenal Switch Results
Bariatric surgery is a tool, and patients who commit to healthier lifestyle habits will experience optimal outcomes. Duodenal switch is a malabsorptive procedure and patients will have to pay close attention to nutrition and take daily supplements in order to maintain adequate vitamin and mineral levels. A successful duodenal switch patient may lose up to 80% of excess body weight within two years of surgery.4
Frequently Asked Questions About Duodenal Switch
What is the difference between gastric bypass and duodenal switch?
During gastric bypass surgery, the size of the stomach is made smaller by creating a small pouch that connects to the small intestine. In duodenal switch surgery, a narrow sleeve is created from a small portion of the stomach, then digestion is rerouted to reduce the calories a patient can absorb.
What are the risks of duodenal switch surgery?
Any surgical procedure is associated with some risks and complications. Risks of duodenal switch surgery include:
- Procedure is not fully reversible
- Possible nutrient deficiency
- More frequent bowel movements
