Introduction. Thorough quality control (QC) study with systemic monitoring and evaluation is
crucial to optimizing the effectiveness of EUS‐FNA. Methods. Retrospective analysis was …

Background Although rapid on-site cytologic evaluation provides high efficacy of EUS-
guided FNA (EUS-FNA), its availability is limited. Alternatively, macroscopic on-site quality …

Endosonography with fine-needle aspiration biopsy (EUS-FNA) has become a widespreadly
available clinical tool to diagnose numerous different lesions in humans. EUS-FNA is …

Background and Aims 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) …

Background Most endosonographers use an EUS needle with an internal stylet during EUS-
guided FNA (EUS-FNA). Reinserting the stylet into the needle after every pass is tedious …

BACKGROUND: The utility of a repeated EUS by experts is not known. OBJECTIVE: To
define the utility of a repeated EUS for the same indication. DESIGN: A retrospective case …

BACKGROUND: EUS-guided FNA is an efficacious technique for sampling intraintestinal
and extraintestinal mass lesions. However, cytology has limitations to its final yield and …

BACKGROUND: The diagnostic yield of EUS-guided FNA (EUS-FNA) of solid pancreatic
masses is a potential benchmark for EUS-FNA quality, because the majority of EUS-FNA of …

BACKGROUND: EUS-guided FNA (EUS-FNA) permits both morphologic and cytologic
analysis of lesions within or adjacent to the GI tract. Although previous studies have …

EUS-guided tissue acquisition (EUS-TA) by FNA (EUSFNA) and fine-needle biopsy (EUS-
FNB) sampling play a pivotal role in the diagnosis of GI and other non-GI malignancies and …
