Randomized trial of contrast-enhanced harmonic guidance versus fanning technique for EUS-guided fine-needle biopsy sampling of solid pancreatic lesions

For EUS-guided fine-needle biopsy sampling (EUS-FNB) of solid pancreatic lesions (SPLs), the role of sampling strategy between targeted biopsy sampling and wide sampling has not been reported. This study aimed to investigate the benefits of the 2 sampling techniques on EUS-FNB using rapid on-site evaluation.
