I dont remember, I want to say they did remove the valve. I know there was an inch of large removed and the rest was in the small intestine. The surgeon just really lead him to believe that it would be an instant relief, and he doesn't really feel any better. So he is very frustrated. Thank you all for responding so quickly. Its nice to know that other people share the frustration of CD and we are not alone. It also helps to have imput from people who have had the surgery, just not hear number and percentages. Thank you again.
