Mucosal dysplasia of the liver and the intraductal variant of peripheral cholangiocarcinoma in hepatolithiasis

Hepatolithiasis combined with intrahepatic cholangiocarcinoma

Hepatolithiasis is a relatively common disease in East Asian countries. It is one of the leading causes of intrahepatic cholangiocarcinoma. The long-term stimulation of bile duct stones and hepatolithiasis-induced bile duct stricture or obstruction cause chronic irritation of cholestasis. In the presence of bacterial infection and other etiological factors, chronic proliferative inflammation of bile ducts will be caused. Eventually, biliary epithelial dysplasia, metaplasia, and even malignant transformation develop. In this paper, we describe the etiology, clinical manifestations, pathological characteristics, imaging diagnosis, and treatment of hepatolithiasis with intrahepatic cholangiocarcinoma. Diagnosis and treatment of hepatolithiasis with intrahepatic cholangiocarcinoma represent a great challenge to surgeons.
