My dad is being treated by Dr. Jarnagin at Memorial Sloan Kettering who I believe is Dr. Fong's Boss.
MSK is an amazing hospital and the Liver/Bile Duct team there is outstanding. While I do not know Dr. Fong directly, Dr. Jarnagin is a brilliant well respected surgeon (Mayo suggested we do the surgery with him rather than at Mayo) and I would be very confident with anyone in his department. The level of organization, attention to detail and focus on patient care at MSK is truly amazing. My dad is 13 weeks out of resection surgery and is doing great. If you decide to come to NY for treatment, please let me know, I am happy to help in any way that I can even if it's just someone to have coffee with (though I can also be helpful with the nurses on the liver floor, we're tight)
For what its worth, I would suggest using a surgeon as close to home as reasonably possible. This surgery is tough and requires a great deal of follow up even with great outcomes. That being said, finding a doctor who is GREAT and who you feel comfortable with is paramount.
I wish you the best in the long and difficult journey.
