Accuracy of visual on-site evaluation (Vose) In predicting the adequacy of Eus-guided fine needle biopsy: A single center prospective study

Endoscopic ultrasound is the standard procedure for the diagnosis of pancreatic lesions and new needles have been developed to improve tissue acquisition (FNB). Rapid onset evaluation (ROSE) decreases the number of needle passes but is not always available. We introduced an easy and rapid method of direct classification of EUS-FNB sample namely Visual on-site evaluation (VOSE).To assess the accuracy of VOSE in predicting the histological...
