Multicenter, randomized comparison of the diagnostic accuracy of 19-gauge stainless steel and nitinol-based needles for endoscopic ultrasound-guided fine-needle biopsy of solid pancreatic masses.

ABSTRACT:

Background

The use of 19-gauge (G) stainless steel needles for endoscopic ultrasound-guided fine-needle biopsy of a pancreatic mass often results in technical difficulties due to an inability to advance the relatively rigid needle out of the endoscope. More flexible nitinol-based needles might decrease such technical difficulties and thus increase diagnostic accuracy.

Objective

In this prospective multicenter randomized single-blinded study we compared the diagnostic value of those two needle types in patients with a solid pancreatic lesion.

Methods

Patients with a solid pancreatic mass were diagnosed with endoscopic ultrasound-guided fine-needle biopsy using one puncture with each needle in a randomized fashion. The primary endpoint was the diagnostic accuracy of eac
