My personal preference would be to make a good effort to save your J pouch, especially if you were pleased with its function prior to your current situation. Dr. Shen and others at Cleveland Clinic are a good choice for necessary medical support. If it is determined that your pouch cannot be saved, you have the options of an end ileostomy and a K pouch or BCIR. When faced with this choice, I selected to go for a BCIR since I adamantly did not want the bag. I wish you the best of luck.
