Comparative accuracy of needle sizes and designs for EUS tissue sampling of solid pancreatic masses: a network meta-analysis

Background and Aims Variable diagnostic performance of sampling techniques during EUS-guided tissue acquisition of solid pancreatic masses based on needle type (FNA versus fine-needle biopsy [FNB]) and gauge (19-gauge vs 22-gauge vs 25-gauge) has been reported. We performed a systematic review with network meta-analysis to compare the diagnostic accuracy of EUS-guided techniques for sampling solid pancreatic masses. Methods Through a systematic...
