ABSTRACT
AIM:
Endoscopic ultrasound (EUS) has become an indispensable method for diagnosis in gastroenterology and new indications for EUS continue to emerge. However, there are limited data regarding the accuracy of EUS-guided biopsy of hepatic focal lesions. The aim of this study was to assess the diagnostic yield of EUS-guided fine needle aspiration (FNA) of focal liver lesions. MATERIAL ANDMETHODS:
We conducted a prospective study in which patients with focal liver lesions, detected by transabdominal ultrasound and computed tomography or magnetic resonance imaging, underwent EUS-guided FNA to determine the diagnostic yield of the procedure.RESULTS:
In 47/48 of patients, the results of EUS-FNA were positive for malignancy, while in one case the acquired fragment was insufficient for appropriate histological analysis. Diagnostic yield was 0.98. In 83% of the cases biopsies were taken from the left lobe and in 17% from the right lobe with the same technical success rate. The most common diagnosis was metastatic adenocarcinoma of the pancreas (26% cases) followed by cholangiocarcinoma (17% cases). Concurrent sampling of other sites in addition to the liver and/or primary tumor was realized in 35% of the cases, with results that correlated with the liver biopsy and with the primary tumor biopsy. We reported no immediate or long-term complications in any of the patients.CONCLUSIONS:
EUS guided fine needle aspiration/biopsy of focal liver lesions is safe, provides a very high diagnostic accuracy and should not be considered only as a rescue method after failure of percutaneous guided biopsies.
