Kay,
Dr. Miller is listed as professor of surgery in the Division of Trauma & Surgical Critical Care here at the university. I am not sure if he is considered a doctor for colonic inertia. I had a condition called diverticilosis and it got infected and ruptured. I had to have emergency surgery that day and Dr. Miller took out the bad part of the intestine and put in the colostomy. All I know is he knew exactly what to do. He left the wound open so that it would heal from the inside out. I am sure if you contacted his office they could fill you in on his expertise.
