Advances in the differential diagnosis of malignant bile duct stenosis / 临床肝胆病杂志

ABSTRACT

There are various etiologies for extrahepatic bile duct stenosis， and pharmacotherapy and endoscopic intervention can achieve a good clinical effect in benign stenosis. Early diagnosis and timely surgical treatment of malignant stenosis may prolong the survival time of patients. However， there are still difficulties in the differential diagnosis of malignant bile duct stenosis. This article reviews the application of serology， radiology， endoscopic techniques， and artificial intelligence in the differential diagnosis of malignant bile duct stenosis， so as to provide strategies and references for formulating clinical diagnosis and treatment regimens.
