Evaluating different techniques for endoscopic ultrasound fine needle biopsy

Diagnostic Efficacy Of 3 Endoscopic Ultrasound-Guided Fine Needle Biopsy Techniques In Solid Masses: A Randomized Clinical Trial

Phase 4 Interventional Hospital Universitario Insular Gran Canaria · NCT05825729

This study is testing three different ways to perform a needle biopsy using endoscopic ultrasound to see which method gives the best results for diagnosing abdominal lesions in patients.

What this trial studies

This study evaluates the diagnostic efficacy of three different endoscopic ultrasound fine needle biopsy (EUS-FNB) techniques: dry suction, slow-pull, and wet suction. It aims to determine which technique provides the best results in obtaining accurate cytological and histological samples from intra-abdominal lesions. The study will involve patients who have been referred for EUS-FNB after imaging tests and will assess factors such as needle size and the number of passes made on the lesion. The findings could help refine biopsy techniques and improve diagnostic accuracy for gastrointestinal cancers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with lesions greater than 1 cm that require biopsy following imaging tests.

Not a fit: Patients with coagulopathy, severe heart or respiratory failure, or those on anticoagulants that cannot be suspended may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of diagnosing intra-abdominal lesions, leading to better patient outcomes.

How similar studies have performed: While EUS-FNB techniques have been widely used, this specific comparison of techniques is novel and has not been extensively tested in prior studies.
