Research advances in intraductal papillary mucinous neoplasm of the bile tract / 临床肝胆病杂志

Intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) is a special type of tumor occurring in the biliary system, with no specific clinical manifestations and imaging findings, and thus it is difficult to diagnose before surgery. It is often considered when a large amount of mucus is found in the bile duct during surgery and then it is forced to change the surgical plan. Clinicians lack an understanding of this disease due to its low incidence rate. This article reviews the recent research advances in the etiology and classification, clinical features, differential diagnosis, treatment, and prognosis of IPMN-B, so as to improve the clinical diagnosis and treatment of IPMN-B among clinicians.
