Diagnostic yield of EUS-guided through-the-needle biopsy in pancreatic cysts
Post written by Antonio Facciorusso, MD, from the Gastroenterology Unit, University of Foggia, Foggia, Italy. The low sensitivity, reported to be as high as 54% in differentiating mucinous from non-mucinous pancreatic cystic lesions (PCLs), represents a major drawback of standard endoscopic ultrasound (EUS) fine-needle aspiration (FNA). Recently, a through-the-needle microforceps biopsy (TTNB) device that can …

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 of smear cytology and liquid-based cytology in EUS-guided FNA of pancreatic lesions
Post written by Kai-xuan Wang, MD, PhD, from the Department of Gastroenterology, Changhai Hospital, Second Military Medical University, Shanghai, China. The objective of this article was to compare the diagnostic efficacy of liquid-based cytology (LBC) and smear cytology (SC) in diagnosing solid pancreatic lesions. The diagnostic efficacy of SC and LBC for cytological samples obtained …
Comparison of liquid-based cytology with conventional smear cytology for EUS-guided FNA of solid pancreatic masses
Post written by Sang Hyub Lee, MD, PhD, and Haeryoung Kim, MD, PhD, from the Department of Internal Medicine and Liver Research Institute, and the Department of Pathology, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, Korea. The purpose of this study was to evaluate the diagnostic …
EUS-guided gastroenteric anastomosis as a bridge to definitive treatment in benign gastric outlet obstruction
Post written by Theodore W. James, MD, from the Division of Gastroenterology and Hepatology, University of North Carolina, Chapel Hill, North Carolina, USA. We evaluated the use of EUS-guided gastroenteric anastomoses for patients with benign gastric outlet obstruction (GOO). We wanted to see if patients were able to successfully avoid surgery using this method. We …
EUS-guided duodenojejunostomy by use of a 2-cm LAMS to treat proximal jejunal stricture in a patient with chronic pancreatitis
Post written by Michael Lajin, MD, from the Sharp Grossmont Hospital, La Mesa, California, USA. A 26-year-old man presented with a 2-week history of nausea and vomiting. His medical history was significant for recurrent pancreatitis secondary to hypertriglyceridemia, infected walled-off necrosis requiring cystogastrostomy, splenic vein thrombosis resulting in severe portal hypertensive gastropathy, and large gastric …
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 …
