What is BPD-DS gastric bypass surgery?
Biliopancreatic diversion with duodenal switch (BPD-DS) affects intestinal hormones in a manner that reduces hunger, increases fullness and improves blood sugar control, making it the most effective approved metabolic operation for the treatment of type 2 diabetes.
The Biliopancreatic Diversion with Duodenal Switch (BPD/DS) is a two-part procedure. BPD-DS combines a sleeve gastrectomy with intestinal bypass, which allows food to bypass part of the small intestine, limiting food intake and resulting in a significant decrease in the absorption of calories and nutrients.
First, a portion of the stomach is removed to create a smaller stomach pouch, shaped like a banana and similar to the sleeve gastrectomy procedure. Then, the bottom part of the small intestine is brought up and connected to the new stomach pouch, bypassing a large portion of the small intestine. Food bypasses roughly 75% of the small intestine, the most of the commonly performed and approved weight loss procedures.
Like other weight loss surgeries, BPD/DS initially helps to reduce the amount of food that can be consumed. This effect decreases over time, and patients of this procedure are eventually able to eat almost "normal" amounts of food. Unlike other procedures, BPD/DS bypasses a large part of the small intestine. This process causes a significant decrease in the absorption of calories and nutrients.
- Among the best results for treating obesity
- Impact on bowel hormones helps create a feeling of less hunger and more fullness
- Most effective procedure for treating type 2 diabetes
- The procedure has a slightly higher complication rates than other procedures
- Highest malabsorption and possibility of vitamins and micronutrient deficiencies
- Reflux and heartburn can develop or get worse
- Risk of looser and more frequent bowel movements
- More complex surgery requiring more operative time
