Touch imprint cytology on endoscopic ultrasound fine‐needle biopsy provides comparable sample quality and diagnostic yield to standard endoscopic ultrasound fine‐needle aspiration specimens in the evaluation of solid pancreatic lesions

Objectives Endoscopic ultrasound‐guided fine‐needle aspiration ( EUS ‐ FNA ) is the gold standard for the diagnosis of solid pancreatic lesions ( SPL s). Cytological samples can also be obtained using touch imprint cytology ( TIC ) on EUS fine‐needle biopsy ( FNB ) specimens. We aimed to compare sample quality and diagnostic yield of EUS ‐ FNA ‐standard cytology ( EUS ‐ FNA ‐ SC ) to that of EUS ‐ FNB ‐ TIC in a series of patients with SPL s....
