Dunny, After my third resection, my doctor ordered Questran for me, a drug that absorbs bile which can cause D. Bile is usually absorbed in the ileum and when that is removed, the bile passes into the colon and can cause D bigtime. You might want to ask your doctor about that. It stopped my D instantly.
I was on TPN temporarily during surgery because my doctor didn't want me to lose too much weight, in fact he sent me home with it after the surgery in case I wasn't able to eat. Fortunately I could. If you do decide to go ahead with it, it doesn't mean you would need it indefinately. It could give your bowel a chance to heal.
Hope you get the answers you need. Moodindigo.
