| [ Summary ] |
The indications for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for pancreatic lesions are as follows：differential diagnosis of benign and malignant lesions and characterization of neoplasms and cancer staging. The sensitivity, specificity and accuracy of EUSFNA for diagnosing pancreatic cancer are reportedly 80-90%, 100%, and 85-95%, respecitvely. The overall complication rate appears to be 0.5-2.5%.
Recently, second generation contrast agents for ultrasonography have been developed and contrast-enhanced harmonic imaging with EUS (CH-EUS) is now available. In a contrast-enhanced harmonic EUS study, using the ExPHD mode, pancreatic tumors were classified into four vascular patterns (avascular, hypovascular, isovascular and hypervascular). |
