Endoscopic ultrasound (EUS) elastography-guided fine-needle aspiration cytology (FNAC) versus conventional EUS FNAC for solid pancreatic lesions: A pilot randomized trial.

Background: Endoscopic ultrasound guided fine-needle aspiration (EUS FNA) is the first-line modality to diagnose suspected solid pancreatic malignant lesions. Elastography-guided FNA has been shown to improve the diagnostic yield of EUS FNA but prospective studies are limited. The aim of the study was to compare diagnostic accuracy, sensitivity and specificity of conventional and elastography-guided EUS FNA in patients with suspected malignant pancreatic solid masses.
