I am having a Proctocolectomy and Ileostomy on Feb.7th.I have already had 2 colostomy surgeries,neither one has functioned right and my new colo-rectal surgeon at the University of Kentucky, says my insides are wrecked and I need the proctocolectomy.I have Crohn's disease that turned into rectal cancer and the Chemo and Radiation did a number on my insides,has anyone else had this problem and how is an ileostomy different from a colostomy.
