Endoscopic ultrasound‐guided fine needle aspiration of pancreatic lesions with 22 versus 25 Gauge needles: A meta‐analysis

Background Robust data in favour of a clear superiority of 22 versus 25 Gauge needles for endoscopic ultrasound‐guided fine needle aspiration are still lacking. Objective We aimed to compare the diagnostic sensitivity, specificity and safety of these two needles for endoscopic ultrasound‐guided fine needle aspiration of solid pancreatic lesions. Methods A computerized bibliographic search was restricted to randomized controlled trials only....
