Prospective Evaluation of Advanced Molecular Markers and Imaging Techniques in Patients With Indeterminate Bile Duct Strictures

DIA, FISH, and IDUS enhance the accuracy of standard techniques in evaluation of indeterminate bile duct strictures, allowing diagnosis of malignancy in a substantial number of patients with false-negative cytology and histology. These findings support the routine use of these newer diagnostic modalities in patients with indeterminate biliary strictures.
