Percutaneous fine needle aspiration biopsy of pancreatic and other abdominal masses

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.
