I had TPN while in the hospital. I improved and did not have to come home with it. TPN gives the gut a rest and that is good for Crohn's. The nutrition will make you feel better. The symptoms of Crohn's will quieten down. At least, this is what it did for me.
I know that when it was discussed that I would be discharged on TPN, a nurse was scheduled to come in 2X a day for a while and then 1X a day. There is not a need for a "pole". I was supposed to be able to go to work with no problems with the TPN.
It really made a tremendous difference for me.
Hugs,
