Active hepatectomy with “tailor-made” treatment can cure refractory biliary dilatation involving intrahepatic bile ducts. At present, there are still some controversies about the range of hepatectomy and the management of type D lesions in children. At the same time, we should pay close attention to the long-term complications after dilated bile duct resection.
