Endoscopic ultrasound-guided tissue acquisition of pancreatic masses

Abstract

Endoscopic ultrasound (EUS) has assumed an increasing role in the management of pancreaticobiliary disease over the past 2 decades but its impact is particularly evident in the management of pancreatic masses. EUS helps improve patients′ outcomes by enhancing tumor detection and staging while providing safe and reliable tissue diagnosis. This review provides an evidence-based approach to the use of EUS for the diagnosis of pancreatic cancer, its staging, and for the determination of resectability compared to other imaging modalities. We will focus on techniques specific to obtaining tissue from solid pancreatic masses and will review best practices in EUS-guided tissue acquisition.
