Initial clinical experience of a steerable access device for EUS-guided biliary drainage

Post written by Vivek Kumbhari, MD, from the Division of Gastroenterology and Hepatology, Johns Hopkins Medical Institutions, Baltimore, Maryland, USA. EUS-guided biliary drainage (EUS-BD) is an accepted method to treat biliary pathology in those that have failed ERCP. A recent consensus statement recommended that of the 4 major EUS-BD techniques, EUS-guided rendezvous should be the …

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 …

Utility of EUS elastography in the diagnosis of gastric subepithelial tumors: a pilot study

Post written by In Kyung Yoo, MD, PhD, from the Department of Gastroenterology, Cha Bundang Medical Center, Cha University College of Medicine, Seongnam-si, Korea. EUS elastography is a real-time imaging technique that displays the tissue elasticity differences between diseased and normal tissues on the conventional B-mode ultrasound images. It analyzes the degree of tissue deformation …

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 …
