Randomized controlled trial of endoscopic ultrasound-guided fine-needle sampling with or without suction for better cytological diagnosis

Abstract

This prospective randomized study showed that EUS-guided fine-needle sampling of solid masses using suction yields a higher number of slides without increasing bloodiness. Although, the proportion of target cells was relatively similar between the suction and non-suction sampling techniques, the sensitivity and negative predictive values of the procedure were significantly higher when suction was added.
