Randomized trial comparing the 22-gauge aspiration and 22-gauge biopsy needles for EUS-guided sampling of solid pancreatic mass lesions.

ABSTRACT:

Background

To overcome limitations of cytology, biopsy needles have been developed to procure histologic samples during EUS.

Objective

To compare 22-gauge (G) FNA and 22G biopsy needles (FNB) for EUS-guided sampling of solid pancreatic masses.

Design

Randomized trial.

Setting

Tertiary-care medical center.

Patients

This study involved 56 patients with solid pancreatic masses.

Intervention

Sampling of pancreatic masses by using 22G FNA or 22G FNB devices.

Main outcome measurements

Compare the median number of passes required to establish the diagnosis, diagnostic sufficiency, technical performance, complication rates, procurement of the histologic core, and quality of the histologic specimen.

Results

A total of 28 patients were randomi
