Biliopancreatic diversion with duodenal switch (BPD/DS)
About this test
A biliopancreatic diversion with duodenal switch (BPD/DS) is a less common weight-loss procedure that is done in two major steps. The first step is sleeve gastrectomy in which about 80% of the stomach is removed. This leaves a smaller tube-shaped stomach the size of a banana. The valve that releases food to the small intestine, called the pyloric valve, remains. A limited part of the small intestine that connects to the stomach, called the duodenum, also remains.
Why it's done
A BPD/DS is done to help you lose excess weight and reduce your risk of possibly life-threatening weight-related health problems, including: Heart disease. High blood pressure. High cholesterol. Severe sleep apnea. Type 2 diabetes. Stroke. Cancer. Infertility. A BPD/DS is typically done only after you've tried to lose weight by improving your diet and exercise habits. But a BPD/DS isn't for everyone who is severely overweight. You likely will have an extensive screening process to see if you qualify. You also must be willing to make permanent changes to lead a healthier lifestyle both before and after surgery. This may include long-term follow-up plans that involve monitoring your nutrition, your lifestyle and behavior, and your medical conditions. Check with your health insurance plan or your regional Medicare or Medicaid office to find out if your policy covers weight-loss surgery.
Risks and complications
As with any major surgery, a BPD/DS poses possible health risks, both in the short term and the long term. Risks associated with BPD/DS are similar to those of any abdominal surgery and can include: Excessive bleeding. Infection. Reactions to anesthesia. Blood clots. Lung or breathing problems. Leaks in the gastrointestinal system. Longer term risks and complications of a BPD/DS may include: Blockage of the bowel, called an obstruction. Dumping syndrome, which can cause diarrhea, nausea or vomiting. Gallstones. Hernias. Low blood sugar, known as hypoglycemia. Malnutrition. Stomach perforation. Ulcers. Vomiting. Ongoing diarrhea. Rarely, complications of a BPD/DS can be fatal.
How to prepare
In the weeks leading up to your surgery, you may be required to start a physical activity program and to stop any tobacco use. Right before your procedure, you may have restrictions on eating and drinking and which medicines you can take. Now is a good time to plan for your recovery after surgery. For instance, arrange for help at home if you think you'll need it.
What to expect
BPD/DS is done in the hospital. The length of your hospital stay will depend on your recovery and which procedure you're having done. When the surgery is performed laparoscopically, your hospital stay may last around 1 to 2 days.
Understanding your results
After a BPD/DS, it may be possible to lose 70% to 80% of your excess weight within two years. However, the amount of weight you lose also depends on your change in lifestyle habits. In addition to helping with weight loss, a BPD/DS may improve or resolve conditions often related to being overweight, including: Gastroesophageal reflux disease. Heart disease. High blood pressure. High cholesterol. Obstructive sleep apnea. Type 2 diabetes. Stroke. Infertility. A BPD/DS also can improve your ability to perform routine daily activities, which could help improve your quality of life.
