I think most of the people on this board who have colonic inertia have had a straight-pull-through, that is their rectum is preserved and their small intestine has been connected to the rectum while tossing the colon. I had j-pouch surgery (removal of colon and rectum) for chronic ulcerative colitis. Hopefully someone with CI will see your post and respond.
