OC-042 Endoscopic Ultrasound Guided Fine Needle Aspiration of Pancreatic Mass Lesions can be Less Accurate with a Metallic Stent in Situ but should not Delay Treatment of Obstructive Jaundice
Abstract:Introduction
Endoscopic ultrasound (EUS) examination and fine needle aspiration (FNA)of the pancreas is now a routine method of obtaining diagnositic tissue for suspected pancreatic mass lesions, however if a biliary self expanding metal stent (SEMS) is in situ it can cast an acoustic shadow and cause local inflammation making EUS visualisation and FNA interpretation more challenging. Despite this it is common for a SEMS to be in place at the time of EUS due to the early treatment required for obstructive jaun… Show more
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.
