If you are getting panreatitis and the blood levels are elevated then the obstruction must be in the common bile duct. This doesn't exclude other problems but the acute symptoms are currently indicating an obstructed bile duct. It would require the ducts to be cleared by the surgeon during the operation.
You have to look through the fear in your mind and make a decision because it can't be left unattended. The only possible solutions are, surgery or liver-flushing.
If the liver-flush doesn't work out you still have a choice!
