Bile Duct Brushings

Slide 6

September 2011

Obtaining bile duct brush cytologic specimens is the usual approach for distinguishing malignant from benign pancreatobiliary strictures. Bile duct strictures are obtained for cytology during endoscopic retrograde cholangiopancreatography or ERCP. The bile duct brushing cytology is important since it is sometimes able to provide a positive diagnosis for cases in which biopsies are negative or often inadequate. These specimens are obtained by passing an endoscope orally down to the level of the ampulla. The instrument used in this technique is a side-viewing instrument, allowing access to the ampulla. The ampulla is cannulated and a wire brush can be passed up the appropriate duct for obtaining cytologic specimens via the brush approach.
