Randomized Trial Comparing the Flexible 19G and 25G Needles for Endoscopic Ultrasound-Guided Fine Needle Aspiration of Solid Pancreatic Mass Lesions.

ABSTRACT:

Objectives

Although a large gauge needle can procure more tissue at endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), its advantage over smaller needles is unclear. This study compared flexible 19G and 25G needles for EUS-FNA of solid pancreatic masses.

Methods

This was a randomized trial of patients undergoing EUS-FNA of pancreatic masses using flexible 19G or 25G needle. Main outcome measure was to compare median number of passes for on-site diagnosis. Secondary measures were to compare specimen bloodiness, complications, technical failures, and histological core tissue procurement.

Results

One hundred patients were randomized to EUS-FNA using flexible 19G or 25G needle. Median of 1 pass was required to achieve on-site diagnosis of 96% and 92% (P = 0.68
