P-LUM-06: Diagnostic accuracy of combined needle use of the new 20-gauge procore fine needle biopsy and the 25-gauge fine needle aspiration needle in solid gastrointestinal lesions

ABSTRACT:

Background and Objectives:

Endoscopic ultrasound (EUS) fine needle biopsy (FNB) needles were designed to improve histologic yield, while maintaining the flexibility to permit ease of use. However, the diagnostic benefit of EUS-FNB needles as compared to the conventional fine needle aspiration (FNA) needles remains unclear. This study aimed to identify the diagnostic accuracy of combined needle use of a new 20-gauge ProCore FNB needle and a 25-gauge FNA needle.

Methods:

For this study, cases were selected in which both the 20-gauge ProCore FNB needle and the 25-gauge FNA needle were used during a single EUS procedure for sampling of a solid pancreatic mass, lymph node, or submucosal mass. Tissue acquisition was performed in the course of the ASPRO trial, a multicenter rand
