A new biopsy needle and its clinical use

Area of Science:

• Interventional Radiology
• Pathology
• Oncology

Background:

• Percutaneous biopsy is crucial for diagnosing various pathologies.
• Minimally invasive techniques are preferred for tissue acquisition.
• The need for simple, effective, and safe biopsy devices persists.

Purpose of the Study:

• To evaluate the efficacy and safety of a new aspirating and severing soft tissue biopsy needle.
• To assess the diagnostic accuracy of the needle for diverse lesions.
• To document any complications associated with its use.

Main Methods:

• A new small, disposable, thin-walled biopsy needle with 3 components was utilized.
• The needle was employed percutaneously for biopsies of chest, abdomen, pelvis, extremities, subcutaneous masses, and lytic spinal bodies.
• Tissue cores were assessed for suitability for histologic cell block preparation.

Main Results:

• Pulmonary biopsies (n=143) achieved 89% diagnostic accuracy.
• Non-pulmonary biopsies (n=81) showed 88% diagnostic accuracy with no complications.
• Complications included 16 small pneumothoraces, 6 large pneumothoraces, and 9 mild hemoptyses in pulmonary biopsies.

Conclusions:

• The new biopsy needle is effective for percutaneous tissue sampling across multiple anatomical sites.
• The device provides sufficient tissue for histological analysis with high diagnostic yield.
• It offers a safe and minimally invasive option for tissue diagnosis, particularly in pulmonary applications.
