Hello Jemison5, This is Leonard from Alamo California. The doctor's are correct, when jaundice appears, it is a clogged bile duct. A stent is needed to drain the bile from the liver. A Klatshin Tumor is usually located in the in the left and right Hepatic Ducts...it looks like a Y just below the liver. A wipple procedure will not be the answer. If surgery is done, and by the way surgery is the only solution to survive the cancer...the doctor will do a procedure called a Roux-en-Y- procedure.
You dad is dealing with a very serious illness. They are not assuming, they will know when they get the results of scans and/or biopsy. They know something if they are using the term Klatskin.
Question: Where id your dad being treated? My wife was told she had 6 weeks, that was in July 2003. Karen is here with me, not perfect but here. keep in mind what I said about surgery...chemo and radiation are not the means to handle this illness. Also, don't lean towards drinking, Karen did drink at all...maybe a glass of wine, maybe.
Also, has you dad been in Southeast Asia or the Pacific Islands in the past 20 years? And yes this illness can be tied to hereditary. They really can not put their finger on the causes. Very little money is spent on bile duct cancer research...all the money is going to breast cancer...and they still can't figure that one out.
Help this helped a little. By the way, I know Alio...she lives in the UK...after hearing Alio's story I hope you don't live there also.
Take care...Leonard from Alamo, CA
