Additional management measures to treat benign biliary obstruction
After an initial drainage procedure, what additional management measures may be performed to treat benign biliary obstruction?
Biliary drainage provides access to the bile ducts that may allow for retrieval of biliary calculi. Balloon dilation of benign ductal strictures with gradual upsizing of drainage catheter diameter may allow for remodeling of the bile duct with eventual relief of obstruction and removal of the drainage catheter. This therapy, which is successful in approximately two thirds of cases, usually takes several months. If unsuccessful, surgical intervention may still be possible, or catheters may be left in place indefinitely.
