Hi Nina,
Welcome to the site. Sorry that you had to find us all here and sorry to hear what you and your husband are going through with everything, but I am glad that you have joined in with us here as you’ll get a load of support and help from everyone here.
I can’t help you with things too much in Germany but hopefully Marion will be along soon and I am sure that she will have more contact info in Germany for you. In the meantime, you could try using the search forum function on the site for others experiences in Germany and if there are posts on this then that will throw them up.
We have this link as well but it doesn’t have much on Germany –
http://cholangiocarcinoma.org/for-patients/major-cancer-centers/
And this from AMMF in the UK with a comprehensive UK list ing of specialists in the UK –

Please let us know how things go, we are here for you.
My best to you,
Gavin
