Comparing the Efficacy of Endoscopic FNA vs FNB in Diagnosing Solid Gastrointestinal Lesions

November 18, 2014 updated by: Stony Brook University

Comparing the Overall Efficacy of Endoscopic Ultrasound Fine Needle Aspiration Versus Fine Needle Biopsy in the Diagnosis of Solid Lesions: A Multicenter, Randomized Clinical Trial

The purpose of this study is to determine if fine needle aspiration or fine needle biopsy is more efficacious and cost-effective than the other while maintaining diagnostic accuracy in the setting of solid gastrointestinal lesions.

Study Overview

Detailed Description

When ultrasound is used during endoscopy, we are able to visualize the structures adjacent to the gastrointestinal tract in close detail. Once the mass is visualized, we use endoscopic ultrasound to obtain a tissue sample, which the pathologist can examine in order to provide a diagnosis.

The conventional method for obtaining a sample of tissue with endoscopic ultrasound is called fine needle aspiration (FNA). This involves the insertion of a thin needle into the mass and obtaining a small sample of tissue which the pathologist can examine. An alternative technique is called fine needle biopsy (FNB), and involves the insertion of a thin double-edged needle into the mass. This double-edged needle may potentially provide a larger sample of tissue to examine.

Both of these techniques are commonly used, and both methods are equally safe. However, it is not known if one of these techniques is more effective at obtaining a sample of tissue or if one of these techniques is more cost-effective than the other. The purpose of this study is to determine if one method is more efficacious and cost-effective than the other while maintaining diagnostic accuracy. The results of this study may alter the way gastroenterologists obtain tissue samples during endoscopic ultrasound, improving the utility of the exam and reducing unnecessary healthcare costs.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Fine needle aspiration (FNA)
Endoscopic ultrasound guided needle tissue acquisition: Tissue acquisition using a standard FNA needle
Endoscopic ultrasound with fine needle aspiration (FNA) allows for the safe and efficacious sampling of solid lesions that are in close proximity to the gastrointestinal tract, including extraintestinal masses, subepithelial tumors, and peri-intestinal lymphadenopathy. Fine needle core biopsy (FNB) has the potential of accruing larger tissue samples during biopsies, which may make the procedure more efficacious. In our study, we are comparing the overall efficacy between these two needles which are currently both used as standard of care.
