Conventional versus contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for diagnosis of solid pancreatic lesions: A prospective randomized trial

Fewer needle passes were required to obtain samples from solid pancreatic lesions using CEH-EUS-FNA than those required using conventional EUS-FNA. Therefore, CEH-EUS-FNA may be more efficient and safer than conventional EUS-FNA for the diagnosis of solid pancreatic lesions.
