Randomized trial comparing the 25G and 22G Franseen needles in endoscopic ultrasound‐guided tissue acquisition from solid pancreatic masses for adequate histological assessment

Background The effects of the Franseen needle size in endoscopic ultrasound‐guided fine‐needle biopsy (EUS‐FNB) of solid pancreatic masses remain unclear. This study aimed to compare 25G and 22G Franseen needles in terms of adequate tissue acquisition from solid pancreatic masses. Methods In this single‐center, crossover, randomized noninferiority trial, eligible patients underwent EUS‐FNB with both 25G and 22G Franseen needles in a randomized...
