Abstract

Background: Rapid 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. Methods: Patients who underwent EUS-guided tissue acquisition of pancreatic mass lesions were retrospectively identified at three tertiary referral centers and those performed with the core needle were included. Adequacy, defined as the rate of cases in which a tissue specimen for proper examination was achieved, with and without ROSE was the primary outcome measure. The diagnostic accuracy and tissue core acquisition were the secondary outcome measures. Results: A total of 333 patients with pancreatic solid mass lesions were included in the study; 140 cases sampled with ROSE and 193 cases without ROSE. The adequacy was 92.1 % in the group sampled with ROSE and 88.1 % in the group without ROSE (p = 0.227). In the ROSE group sensitivity, specificity, and accuracy were 90.7, 100 and 92.1 %, respectively. In the group without ROSE, sensitivity, specificity, and accuracy were 87.2, 100, and 88.1 %, respectively. No difference for all these figures was observed between the two groups. The tissue core was available in 61.4 and 53.4 % of cases with and without ROSE, respectively (p = 0.143). Conclusion: In the absence of ROSE, EUS-based tissue acquisition with Core needle should be considered since it achieves comparable tissue sampling adequacy and accuracy.
