whats the difference?
I think pictures/diagrams are most helpful here. Do a google search and click images, pictures of both should come up. They are very different ways to restrict the size of our stomaches. IN RNY ours is stapled in half and then cut apart and sewn over. A length of small intestine is bypassed to produce malabsorption.
IN Lap band a restricting inflatable ring is placed around the stomach. Over certain periods of time the ring is gradually inflated via a port which is in the abdomen.
Check out the images.
