Background and Aims Several studies have compared EUS-guided FNA with fine-needle
biopsy (FNB), but none have proven superiority. We performed a multicenter randomized …

Background and Aims EUS-guided FNA primarily provides cytologic samples. EUS-guided
fine-needle biopsy (FNB) with needles that provide histologic specimens may enhance …

Background and Aims Two second-generation, flexible EUS fine-needle biopsy (FNB)
needles have been marketed recently in the United States. Thus far, there have been no …

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 …

BACKGROUND: Current limitations of EUS-guided FNA include the need for multiple
passes and on-site cytology assessment and lack of core specimen. Recently, a new 25 …

Background and Aims EUS-guided fine needle biopsy (FNB) sampling and FNA are
important methods for obtaining core tissues and cytologic aspirates. To improve the …

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 and Aim Recently, a 22‐gauge (G) needle with a Franseen tip design was
developed for endoscopic ultrasonography‐guided fine‐needle biopsy (EUS‐FNB). The …

Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is effective
for tissue diagnosis of pancreatic mass. To improve diagnostic yield and drawbacks, 22 …

BACKGROUND: There is a lack of prospective, randomized studies comparing the
diagnostic yield and complication rates of 22-gauge and 25-gauge needles during EUS …
