Impact of EUS-guided fine-needle biopsy sampling with a new core needle on the need for onsite cytopathologic assessment: a preliminary study.
FNA is the primary method of EUS tissue acquisition. In an attempt to improve our yield of EUS-guided tissue acquisition, we compared fine-needle biopsy (FNB) sampling without rapid onsite evaluation (ROSE) with FNA with ROSE and assessed the concordance of FNA and FNB sampling. ⋯ FNB sampling without ROSE using a dedicated core needle performed as well as FNA with ROSE in this small cohort, suggesting that FNB sampling with this new core needle may eliminate the need for an onsite cytopathologic assessment, without loss of diagnostic accuracy.
