Q

How does a laprascopic gastric bypass work?

A
  • Makes a pouch of the upper stomach
  • Connect Jejunum direct to the stomach pouch
  • Connect duodenum to further down jejunum.

This means you don’t eat so much and it bypasses some of the small bowel (while still allowing gastric acid/bile/pancreatic enzymes to reach the main tube.
