Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) can be inconclusive in diagnosing solid pancreatic masses. The aim of the present study was to evaluate the impact of an inconclusive EUS-FNA in the management of patients with solid pancreatic masses. ⋯ Inconclusive EUS-FNA could lead to unnecessary surgical procedures in patients with resectable solid pancreatic masses if no cytopathological diagnosis is obtained through either repeat or alternative diagnostic modalities. Repeat EUS-FNA provided a conclusive diagnosis in a majority of cases, and therefore should be strongly considered ahead of other modalities.
