Roux-en-Y Gastric-Bypass

How does the Gastric-Bypass work?
- A small, 15 to 20cc, pouch is created at the top of the stomach.
- The small bowel is divided. The biliopancreatic limb is reattached to the small bowel.
- The other end is connected to the pouch, creating the Roux limb.
- The small pouch releases food slowly, causing a sensation of fullness with very little food.
- The biliopancreatic limb preserves the action of the digestive tract.
