This makes me so angry, that they would even say you would have a bag! If by chance you ever need to have your colon removed, you will not have to have a bag, you can have a J-Pouch which means they remove your colon, attach your small intestine to it and your small intestine acts as your colon. My son has this. You are wise to keep getting others opinions on this. MD Anderson in Texas is world renowned for their works with this, so if the Mayo can't help, try them.
