EUS-Guided Fine-Needle Aspiration of Suspected Hilar Cholangiocarcinoma in Potentially Operable Patients with Negative Brush Cytology

Abstract

These results suggest that EUS-FNA is of value as a new, less-invasive approach for tissue diagnosis of hilar strictures of unknown cause. It was technically feasible without significant risks, when other diagnostic tests were inconclusive and was able to change preplanned management in about half of the patients.
