BACKGROUND： Endoscopic ultrasound-guided fine-needle aspiration cytology was demonstrated to be a useful tool for the diagnosis and staging of pancreaticobiliary neoplastic le- sions. Nonetheless, the diagnostic value of this procedure may be limited by low cellularity of the specimen, contamination of intestinal cells and unfeasibility of ancillary immunocy- tochemical procedures. The present study was to evaluate its usefulness in the diagnosis of neoplastic lesions.
