Diagnostic yield of small histological cores obtained with a new EUS-guided fine needle biopsy system

As endoscopic ultrasound-guided tissue acquisition techniques evolve, there is increasing interest in obtaining optimal histological samples to improve diagnostic accuracy. In this study, we aimed to assess the tissue acquisition success rate and test performance characteristics of a novel endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) system. We performed a retrospective review of consecutive patients undergoing EUS-guided tissue...
