Indeterminate Biliary Strictures

Interventions

dual-lumen catheter-guided mini-forceps biopsy is performed first:In ERCP procedures, catheter-guided mini-forceps biopsy is performed before biliary brush cytology.
Biliary brush cytology with vacuum aspiration is performed first:In ERCP procedures, biliary brush cytology with vacuum aspiration is performed before dilation catheter-guided mini-forceps biopsy.
