Randomized trial comparing fanning with standard technique for endoscopic ultrasound-guided fine-needle aspiration of solid pancreatic mass lesions

Background and study aims: The fanning technique for endoscopic ultrasound-guided fine-needle aspiration (EUS – FNA) involves sampling multiple areas within a lesion with each pass. The aim of this study was to compare the fanning and standard techniques for EUS – FNA of solid pancreatic masses. Patients and methods: Consecutive patients with solid pancreatic mass lesions were randomized to undergo EUS – FNA using either the...
