Comparative accuracy of needle sizes and designs for EUS tissue sampling of solid pancreatic masses

Post written by Antonio Facciorusso, MD, PhD, from the Endoscopy Unit, University of Foggia, Foggia, Italy. EUS-guided tissue acquisition (EUS-TA) for cytology through fine-needle aspiration (FNA) or fine-needle biopsy (FNB) using specialized core needles has become a central technique in the assessment of pancreatic masses. The most important pitfall associated with this procedure is a …

EUS-FNA of 2 right atrial masses

Post written by Rafael Romero-Castro, MD, PhD, from the Hospital Universitario Virgen Macarena, Seville, Spain. We report EUS-FNA in 2 patients with right atrial masses, 1 of them requiring 3 passes to obtain diagnostic cytologic material. I think these 2 cases deserve to be known by the community of endosonographers because of 2 main reasons. …

A trial comparing a 25-gauge EUS-FNA device with a 20-gauge EUS-FNB device

Post written by Priscilla A. van Riet, MD, from the Department of Gastroenterology and Hepatology, Erasmus MC University Medical Center, Rotterdam, the Netherlands. Our study focused on the optimization of EUS-guided tissue sampling. For this, we compared the diagnostic performance of a newly designed FNB needle, the 20G ProCore needle with a forward-facing bevel, to …

The 25G EUS-FNA needle

Shyam Varadarajulu, MD from the Center for Interventional Endoscopy at Florida Hospital in Orlando, Florida, USA discusses his Original Article "The 25G EUS-FNA needle: Good for onsite but poor for offsite evaluation?" When rapid onsite cytology evaluation is not available, cell block is used as a technique for off-site interpretation of endoscopic ultrasound-fine needle aspiration …
