Hello Sweet green, I am sorry for your loss of your husband, I am a resected cc patient and recently an MRI indicated the site of my bile duct resection is becoming restricted, and I questioned what to do,concerned this could be the beginning of it’s return, the doctors all consulted one another, took a while and they came back with “it is scar tissue building up at the site of duct resection, if it becomes a problem, stent it.” and he added, yours is a variety of cc that is “cyst like” I believe he said, and not to worry about it . ??Reading this article makes cystic bilary tumors worse than cc with equally bad survival numbers. I am very blessed in many ways, it seems my bile duct cleared itself, and I can eat chicken skin without pain if I wish (love it, can do a little ) So who knows ? If I had rushed to get a stent then they need bimonthly replacement and now you risk pancreatitis every time you get one.You are your own advocate and educate yourself and make your own decisions. I am the only one in my family with any symptoms of liver problems. I have not seen my onc since all of this, I am due in feb. sometime. Perhaps I will learn more then….best wishes, Pat
