What is the number of anastomotic sites in BPD/DS?

In biliopancreatic diversion with duodenal switch (BPD/DS), there are indeed two primary anastomotic sites involved in the procedure. The first is the anastomosis between the stomach and the ileum, where a portion of the stomach is connected to the ileum after a significant portion of the stomach is removed. This allows for both restrictive and malabsorptive components to aid in weight loss.

The second anastomosis is formed between the duodenum and the ileum after the bypass. This portion helps ensure that bile and pancreatic juices can mix with food at the appropriate point in the digestive tract, allowing for some normal absorption of nutrients, while also promoting the malabsorptive effects that contribute to weight loss.

The specific design of the BPD/DS aims to maximize weight loss while still allowing for some nutrient absorption, which is crucial for patient health. Understanding the number of anastomotic sites involved in this procedure provides insight into the surgical complexity and the impact on the patient’s digestive function post-surgery.
