Endoscopic ultrasound (EUS)-guided fine needle aspiration with or without biopsy (FNA/FNB) are the primary diagnostic tools for gastrointestinal submucosal tumors. EUS-guided fine needle aspiration (EUS-FNA) is considered a first line diagnostic method for the characterization of pancreatic and upper gastrointestinal lesions, since it allows for the direct visualization of the collection of specimens for cytopathologic analysis. EUS-FNA is most effective and accurate when immediate cytologic assessment is permitted by the presence of a cytopathologist on site. Unfortunately, the accuracy and thus the diagnostic yield of collected specimens suffer without this immediate analysis. Recently, a EUS-FNB needle capable of obtaining core samples (fine needle biopsy, FNB) has been developed and has shown promising results. This new tool adds a new dimension to the diagnostic and therapeutic utility of this technique. The aim of the present review is to compare the efficacy of EUS-FNA to that afforded by EUS-FNB in the characterization of pancreatic masses and of upper and lower gastrointestinal submucosal tumors.
Endoscopic ultrasound (EUS)-guided transluminal drainage of obstructed bile duct with conventional metal and plastic stents has been in practice for several years, but this modality carries its own potential complications and obstacles. Nevertheless, the novel Hot AXIOS stent (Boston Scientific Corp., Marlborough, MA) has been shown to overcome some of those factors, which justifies its application in a variety of clinical indications, such as EUS-guided choledochoduodenostomy (EUS-CDS) for biliary drainage after failed endoscopic retrograde cholangiopancreatography. We present a case of EUS-CDS with an electrocautery enhanced lumen-apposing stent for biliary drainage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
