Usefulness of endoscopic ultrasound‐guided sampling using core biopsy needle as a percutaneous biopsy rescue for diagnosis of solid liver mass: Combined histological‐cytological analysis

Endoscopic ultrasound (EUS)‐guided fine needle aspiration (EUS‐FNA) is one of the alternative methods for tissue sampling of liver solid mass. However, the diagnostic efficacy using cytology alone was limited. In this study, we evaluate the diagnostic accuracy of EUS‐guided fine needle biopsy (EUS‐FNB) as a percutaneous biopsy rescue for liver solid mass.
