After (what felt like) a million e-mails to various people all over Europe, I have organized the following:
I will get my low-profile j-tube (through my existing gastrostoma) either on the 25th or 26th of October. I also have my friend's Dad on board now, who is an interventional radiologist - he will do my tube changes from now on. I still have to call him tomorrow and talk to him in person, but my friend already talked to him today.
I am so looking forward to the switch! And I really hope my jejunum will start to adapt to the feeds quickly.
I will be the only person in Austria that has this fancy Mic-key low-profile j-tube!
