Abstract

Rapid onsite evaluation (ROSE) following endoscopic ultrasonography (EUS)-guided fine-needle aspiration contributes to the establishment of a diagnosis for various organs. Newly designed three-plane symmetric needles for EUS-guided fine-needle biopsy (EUS-FNB), such as the Franseen needle, have been developed to enable histological core tissue acquisition. However, EUS-guided tissue acquisition for hypervascular splenic lesions remains challenging. Tissue acquisition in cases of splenic malignant lymphoma by using a conventional needle with multiple strokes and suction may result in indeterminate ROSE due to blood contamination and tiny fragments of lymphoma tissue, whereas EUS-FNB by using the Franseen needle with a minimal number of strokes with suction demonstrates qualified specimens for the ROSE as well as histological examination. For splenic malignant lymphomas, EUS-FNB by using the Franseen needle with a limited number of strokes may facilitate qualified specimen acquisition.
