Type IV

The dilated extrahepatic duct is completely excised and a Roux-en-Y hepaticojejunostomy is performed to restore continuity. Intrahepatic ductal disease does not require dedicated therapy unless hepatolithiasis, intrahepatic ductal strictures, and hepatic abscesses are present. In such instances, the affected segment or lobe of the liver is resected.
