Condition: Pancreatic Masses · Sponsor: Mahidol University
Endoscopic Ultrasound-Guided Fine Needle Aspiration (EUS-FNA) is a well-established technique for pancreatic tissue acquisition, offering a high diagnostic accuracy ranging from 78% to 95%, along with a favorable safety profile. Over time, numerous studies have sought to optimize this procedure by investigating various contributing factors, including needle size, sampling techniques, adequacy of tissue acquisition, the number of passes required, and needle type. These insights have largely been incorporated into routine clinical practice, refining the diagnostic capabilities of EUS-FNA. Despite its widespread use, EUS-FNA has limitations, particularly in the diagnosis of certain pancreatic pathologies such as lymphoma, gastrointestinal stromal tumors (GISTs), and autoimmune pancreatitis. These conditions often require histologic samples for ancillary studies, which cytologic specimens obtained via FNA cannot sufficiently provide. To overcome this limitation, Fine Needle Biopsy (FNB) needles were developed. These needles enable the procurement of core tissue samples, thereby enhancing histopathological assessment and reducing reliance on rapid on-site cytological evaluation (ROSE). Additionally, FNB allows for fewer needle passes, which can shorten procedure time and reduce associated complications. Among FNB technologies, the third generation of needles has garnered particular attention due to improved sample adequacy and diagnostic reliability. While earlier research compa…
