Randomized trial comparing the Franseen and Fork-tip needles for EUS-guided fine-needle biopsy sampling of solid pancreatic mass lesions

Background and Aims Recently, a 3-plane symmetric needle with Franseen geometry and a Fork-tip biopsy needle have been developed for histologic tissue procurement. We compared 22-gauge Franseen and 22-gauge Fork-tip needles in patients undergoing EUS-guided sampling of pancreatic masses. Methods Fifty patients underwent sampling using both 22-gauge Franseen and 22-gauge Fork-tip needles, with randomization of needle order. Two dedicated passes...
