Background
The sensitivity of brush cytology for biliary strictures has typically been low, usually 30%‐60%. We compared the cellular yield and diagnostic accuracy using a new cytology brush (n = 16) versus standard biliary brushings (n = 16) in 32 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with brushings for evaluation of a biliary stricture for malignancy.
Methods...
Background: Diagnosis of a biliary stricture often hinges on cytological interpretation. In the absence of accompanying stroma, these results can often be equivocal. In theory, advanced shave biopsy techniques would allow for the preservation of tissue architecture and a more accurate definition of biliary pathology.
Objectives: We sought to determine the initial diagnostic utility of the modern...
