Biliary tract brush cytology is increasingly being recognized as a favoured method for evaluating abnormalities of the biliary tract. In order to increase the diagnostic accuracy, we devise a new brush processing method finalized to the complete and ideal cytologic examination of the collected material. Small fragments of the mucosa, of inflammatory cell aggregates or of carcinomas are observed and the results are optimally fixed and allow a definitive histological diagnosis.

Abstract
Biliary tract brush cytology is increasingly being recognized as a favoured method for evaluating abnormalities of the biliary tract. In order to increase the diagnostic accuracy, we devise a new brush processing method finalized to the complete and ideal cytologic examination of the collected material. Small fragments of the mucosa, of inflammatory cell aggregates or of carcinomas are observed and the results are optimally fixed and allow a definitive histological diagnosis.
