What is duodenal switch surgery?

Duodenal switch surgery is an advanced procedure that modifies both the stomach and small intestine. By rerouting part of the duodenum away from direct connection with the stomach, it enables food to bypass a significant portion, potentially rendering gastric bypass surgery unnecessary.

This innovative bariatric surgery has emerged as one of the most effective options for weight loss. On average, patients experience a weight loss of 80.8 pounds more compared to gastric banding.

Although reversible, duodenal switch surgery carries its own risks. Continue reading for further information on these risks.

How does duodenal switch surgery work?

Switch surgery combines both restrictive and malabsorptive techniques. Surgeons create a smaller stomach pouch, leaving about 40% of its original amount of food intake. Additionally, a portion of the small intestine is redirected to this pouch, reducing nutrient absorption. 

This rearrangement involves attaching the duodenum directly above the bypassed section rather than passing beneath it.

The gastric reduction duodenal switch operation

For DS switch surgery, you’ll be under general anesthesia to stay unconscious. Here’s the process:

  1. A small incision in your abdomen guides the surgeon with a camera.
  2. The surgeon removes a portion of the stomach to form a new pouch using staples or stitches.
  3. The new pouch is connected to a section of the intestine, creating two separate pouches for digestion.
  4. Any remaining parts of the stomach are sealed to create a “J-Pouch” valve for bile flow.
