Initially described by Vilmann et al. in 1992 1, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a validated diagnostic procedure in the field of gastrointestinal pathology. It is the current standard of care for sampling pancreatic mass lesions, with reported sensitivities ranging from 64 % to 95 %, specificities from 75 % to 100 %, and diagnostic accuracies from 78 % to 95 % 2. However, the actual efficacy of EUS-FNA in practice depends on the site, size, and characteristics of the target tissue 3, as well as the availability of a cytopathologist to render an on-site diagnosis 4. In order to overcome some of the limitations of FNA, needles designed to obtain biopsy specimens (fine-needle biopsy [FNB] needles) have been developed that allow core samples to be collected by shearing tissue from the target lesion. The expectation is that cutting needles will improve diagnostic ac...
