Lainy: I have to respond to your last post. When they 'killed' Tom's tumor that was 'blocking' the bile duct, the radiation also apparently destroyed that bile duct so that is why they could not get a stent internalized. Bile ducts can also become 'restricted' or 'narrowed' which would cause the bili level to climb as the bile is not flowing through that restricted bile duct. Many times a tumor can completely block a bile duct which would also cause the bili level to climb.
Scar tissue can also 'block' a bile duct. Scar tissue from a 'dead' tumor, or scar tissue from a surgery. All of these things can result in a person's bili level to climb.
Additionally there are a whole host of other things that can cause the bili levels to climb. Even a tube exchange will call the bili level to rise, or an infection in the liver.
Don't want to step on anyone's toes, but just had to chime in on this one.
Hugs,
Margaret
