Hi Linda,
Sorry to hear what you're going through, that is a difficult diagnosis.
Hopefully others will confirm my thoughts regarding a surgeon. I believe you need to see a hepatobilliary specialist. A surgeon that does these types of surgeries often. You don't want any surgical procedure having to do with the liver and bile ducts done by just a general surgeon. In other words, don't let them practice on you.
In November of '08 we took my mother to Abbott Northwestern in Minnesota ( 1,000 miles away ) to see a hepatobilliary specialist that came recommended to us. My mom had the horrible Whipple surgery and has come through it very well with no complications.
You can find out what your surgeon recommends, but I would definitely have a specialist do any surgery. Don't know why you would need to see and oncologist right now unless surgery isn't an option.
If you want the name of the surgeon that did my mom's surgery, just send me a private message and I will locate the contact numbers for his assistant. We just called and went there and worried about the insurance later.
I believe it's very important for you to act quickly. Be your own advocate, you'll need help with this.
Did they do a fine needle biopsy or ERCP, how did they confirm it was malignant?
