Monocentric study of bile aspiration associated with biliary brushing performed during endoscopic retrograde cholangiopancreatography in 239 patients with symptomatic biliary stricture

The cytologic diagnosis obtained by brushing or biopsy in malignant biliary strictures is considered to be highly specific but poorly sensitive. The diagnostic association of biliary brushing and bile exfoliate cytology has been suggested but is rarely performed in clinical practice. The objective of this study was to assess the diagnostic performance of bile aspiration associated with biliary brushing during therapeutic endoscopic retrograde cholangiopancreatography (ERCP).
