Repeat EUS-FNA of pancreatic masses after nondiagnostic or inconclusive results

Post written by Andrea Lisotti, MD, from the Gastroenterology Unit, Hospital of Imola, Department of Medical and Surgical Sciences, University of Bologna, Bologna, Italy. Endoscopic ultrasound (EUS) has a pivotal role in the management of pancreatic cancer, one of the most lethal neoplasms with a 5-year survival that has not significantly increased over the last …

Comparison between fine-needle biopsy and fine-needle aspiration for EUS-guided sampling of subepithelial lesions

Post written by Antonio Facciorusso, MD, PhD, from the Gastroenterology Unit, University of Foggia, Foggia, Italy. Endoscopic ultrasound (EUS) fine-needle aspiration (FNA) did not prove to outperform bite-on-bite biopsy in patients with subepithelial lesions (SELs) showing a pooled diagnostic yield as high as 60%. Based on this evidence, current guidelines recommend EUS-guided sampling only in …

On-site stereomicroscope quality evaluations to estimate white core cutoff lengths using EUS-FNA biopsy sampling

Post written by Kosuke Okuwaki, MD, PhD, from the Department of Gastroenterology, Kitasato University School of Medicine, Kanagawa, Japan. The primary aim of this prospective exploratory study was to use stereomicroscopy to estimate the stereomicroscopically visible white core (SVWC) cutoff length required for the pathological diagnosis of samples obtained using 22-gauge needles. Rapid on-site cytologic …

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 …

Endoscopic unroofing drainage with a needle-knife for gastric wall abscess

Post written by Yusuke Hashimoto, MD, from the Department of Hepatobiliary and Pancreatic Oncology, National Cancer Center Hospital East, Kashiwa, Japan. This case describes a 68-year-old diabetic woman was referred for evaluation of a pancreatic tail mass (maximum diameter, 3.2 cm). To obtain specimens for histologic examination before neoadjuvant chemotherapy, transgastric EUS-FNA was performed with …

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 …
