There are few reports on the histological diagnostic ability of endoscopic ultrasonography‐guided fine needle aspiration (EUS‐FNA) in a large‐series of pancreatic masses. In the present study therefore we retrospectively evaluated the histological diagnostic ability of EUS‐FNA in pancreatic masses without on‐site cytopathologist. In 355 patients with pancreatic solid masses, EUS‐FNA was carried out. EUS‐FNA histology showed accuracy, 90.7%; sensitivity, 89.5%; specificity, 95.6%; positive predict value, 98.8%; negative predict value, 68.8% by intention‐to‐treat analysis. Except for 10 with inadequate materials, EUS‐FNA histology showed accuracy, 93.3%; sensitivity, 91.8%; specificity, 100%; positive predict value, 100%; negative predict value, 77.6%. The mean number of puncture was 2.88 (range 1 to 8). There was two (0.6%) procedure‐related bleeding. In conclusion, diagnostic ability of EUS‐FNA by histological materials was similar to previous literature on the EUS‐FNA without on‐site cytopathologist.
