There is one guy here with short bowel syndrome (solely due to Crohn's, no cancer involved) and who has been on TPN for 13 years. He hasn't posted in a long time unfortunately :-/
There is also a UK guy called Michael Seres who had a small bowel transplant for Crohn's and short gut syndrome, and who was on TPN for years. He has a website:
www.michaelseres.com/. Maybe your son-in-law could consider having a small bowel transplant...?
I'm sorry, I don't have anything else, but I do hope your son-in-law can find the specialist care he clearly needs :-/
Edit: Great minds think alike... >.>
