Fluoroscopically guided thin needle aspiration biopsy of the abdomen and retroperitoneum

The results of 49 transabdominal and translumbar thin needle percutaneous aspiration biopsies in patients suspected of having malignant disease are reported. A correct diagnosis was obtained in 40 cases. Placement of the Chiba needle was accomplished by fluoroscopically controlled biplane radiography during constrast examinations. No complications were encountered. The technique allows cytologic diagnosis of malignancy without high risk exploratory surgery, prolonged hospitalization, or delay of treatment. Use of fluoroscopic needle guidance and biplane radiography for confirmation of position using various contrast examinations as markers is felt to be superior to either CT or ultrasound. The technique is readily available in all radiology departments.
