Core Tip

Core Tip: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) has been established in the evaluation of pancreatic masses and recently developed fine needle biopsy (FNB) needles improve the diagnostic yield of EUS-TA providing tissue blocks for performing immunohistochemistry and flow cytometry. We prospectively evaluated the Franseen needle when sampling pancreatic solid lesions. EUS-FNB with the 22-gauge Franseen needle achieved a high rate of histological core procurement and high diagnostic accuracy after only two passes and flushing out the acquired samples directly into formalin, without a rapid on-site evaluation by a cytopathologist or macroscopic on-site evaluation by the endoscopist.
