I too have lost my valve but luckily I don't have D all the time. Some people that have problems after resection with D use Questran to help firm up their stool. Maybe you could ask your GI about
it. Also, my second resection was because I had another stricture at the reconnection site. I was told that when Crohns returns after a resection it usually comes back at the reconnection site....Hope that helps.
