Mixed feelings about the Dr's appt.

Today I was told about all my results. So, the biopsy is great, the liver is doing good. No virus attacking or anything weird. The the blood test, even better that the last one. But according to the MRI I have a little stenosis and so they want to do a RCP to see if I need a stent in the bile duct.
Anyway, I don't understand if the blood test don't show anything why they want to do this. After all, it's a type of surgery, and I am not sure if we shouldn't wait until it starts bothering me, like getting a little yellow, or something similar. I think I will talk to another surgeon of the team and see if he can explain to me why I should do this.
Well, I have until the 29th of April to think about it. That's my next appointment.
