Maybe to manage his pain and to get some food into him he should be in the hospital. People who are in pain, depressed and not eating properly... well it's a downward spiral. Ideally they should put him in give him an NG tube and IV (for pain meds and fluid). Otherwise he'll be in brutal shape for the surgery and healing will be that much harder. Also if he is in the hospital if something happens (like a cancellation) - he's ready to go - they'll take him. JMHO best of luck
