Contrast-enhanced harmonic endoscopic ultrasound-guided fine-needle aspiration versus standard fine-needle aspiration in pancreatic masses: a meta-analysis

It is still unclear whether endoscopic ultrasound (EUS) contrast-enhanced fine-needle aspiration (CH-EUS-FNA) determines superior results in comparison to standard EUS-FNA in tissue acquisition of pancreatic masses. Aim of this meta-analysis was to compare the diagnostic outcomes of these two techniques.We searched the PubMed/Medline and Embase database through October 2020 and identified 6 studies, of which 2 randomized controlled trials...
