The presence of rapid on-site evaluation did not increase the adequacy and diagnostic accuracy of endoscopic ultrasound-guided tissue acquisition of solid pancreatic lesions with core needle
BackgroundRapid on-site evaluation (ROSE) improves the adequacy and accuracy of EUS-guided tissue acquisition, although it is not routinely widely available. Evidence suggested that core needles might overcome the absence of ROSE. The aim of this study was to evaluate the influence of ROSE on the adequacy and accuracy of EUS-guided tissue acquisition with core needles in patients with pancreatic solid lesions.
