Intrahepatic bile duct papilloma (IPNB) is a rare benign tumour from the bile duct epithelium and has a high malignant transformation rate. Early radical resection can obviously improve the prognosis of patients, but it is difficult to be sure of the diagnosis of IPNB before operating.
This study included 28 patients with intraductal papilloma admitted to the First Hospital of Jilin University from January 2010 to November 2020 and recorded their clinical manifestations, imaging features, complications and prognosis. There were 12 males and 16 females with an average age of 61.36 ± 8.03 years. Most patients had symptoms of biliary obstruction. Biliary dilatation and cystic mass could be seen on imaging. After surgery, IPNB was diagnosed by pathology.
IPNB is a rare benign tumour in the bile duct. Early diagnosis and timely R0 resection can improve the prognosis of IPNB.
Core Tip: Intrahepatic bile duct papilloma (IPNB) is a rare benign tumour in the bile duct. An early radical operation can improve the prognosis. This study analysed the clinical manifestations, imaging features, complications and prognosis of IPNB. IPNB should be considered in patients with bile duct recurrent infection, cholestasis and biliary obstruction, if imaging examination shows cystic dilatation of the bile duct, if there are mural nodules or papillary tumours with delayed enhancement, if the cystic-solid tumours communicate with the bile duct and if the upstream and downstream bile ducts dilate.
