Abstract

Since its introduction in the early 1980s, endoscopic ultrasound (EUS) has revolutionized the imaging of the pancreas. The technique has proved reliable in the detection and assessment of small pancreatic lesions and accurate in the preoperative staging of pancreatic carcinoma when compared with other techniques such as abdominal ultrasound, endoscopic retrograde cholangiopancreatography, computed tomography, and nuclear magnetic resonance imaging. Other indications in which EUS has shown to be valuable include acute and chronic pancreatitis, tumors of the papilla of Vater, choledocholithiasis, as well as common bile duct tumors. Interventional EUS, including fine-needle aspiration puncture of pancreatic tumors and celiac plexus neurolysis for the palliation of pain in chronic pancreatitis or pancreatic carcinoma, is increasingly being performed. In this article, EUS imaging in pancreatic diseases is described, pointing out its uses and accuracy in various lesions.
