Percutaneous Fine Needle Aspiration Biopsy of Pancreatic and Other Abdominal Masses

Abstract

Percutaneous fine needle aspiration biopsy of 18 patients with pancreatic masses, and 19 with other intra-abdominal tumors, showed it to be a safe, accurate procedure. A diagnostic biopsy yield was obtained in over 85% of the cases without clinical complications. Indications for fine needle biopsy are: (a) to avoid surgery by obtaining a histologic diagnosis; (b) to determine the staging of a neoplastic disease process; and (c) to facilitate treatment planning. The technique of "skinny needle" biopsy is discussed.
