Loop Duodenal Switch

The loop duodenal switch (L-DS) is a single-anastomosis biliopancreatic diversion with a duodenal switch (BPD-DS) procedure. The original BPD-DS has two-anastomosis and is an accepted and approved bariatric procedure by the American Society of Metabolic and Bariatric Surgery.
  • Preserving the pylorus has many advantages over the traditional duodenal switch procedure (BPD-DS or biliopancreatic diversion with duodenal switch).
  • Some advantages to note are less risk for ulcers, bile reflux gastritis, hypoglycemia, nutritional deficiencies or dumping syndrome.
  • In addition, using a loop of intestine to connect the stomach to rather than a traditional Roux limb, allows for only one connection needed rather than the original two decreasing the risk for a leak and eliminating the later risk of an internal hernia.
