Overview
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.
The second step changes the digestive tract to bypass most of the intestine by connecting the end part of the intestine to the duodenum near the stomach. A BPD/DS both limits how much you can eat and reduces the absorption of nutrients, including proteins and fats.
BPD/DS is generally done as a single procedure; however, in some circumstances, the procedure may be performed as two separate operations — sleeve gastrectomy followed by intestinal bypass once weight loss has begun.
While a BPD/DS is very effective, it has risks, including malnutrition and vitamin deficiencies. This procedure is generally recommended for people with a body mass index (BMI) greater than 50.
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.
