1128 endoscopic ultrasound is effective for identifying malignant regional lymph nodes in patients with cholangiocarcinoma prior to curative resection or liver transplantation

Both incidence and mortality of cholangiocarcinoma (CCA) are increasing worldwide. The presence of malignant regional lymph node (MRLN) involvement precludes curative surgical resection or liver transplantation. Thus it is critical to determine the status of indeterminate regional lymph nodes (IRLN) during staging. Cross sectional imaging lacks sufficient sensitivity for IRLN identification and poorly discriminates benign from MRLN when IRLN are identified. While limited data have supported the utility of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for detection of MRLN in perihilar CCA (pCCA), there is no data for its role in staging of intrahepatic CCA (iCCA).
