Percutaneous fine-needle aspiration biopsies were performed in 51 patients with various intra-abdominal masses localized by palpation, radiologic studies, ultrasonography or radioisotope scanning. Biopsy specimens were considered positive for malignant disease in 35 (85%) of the 41 patients with such disease, including 26 (96%) of the 27 with metastases. There was one false-positive diagnosis of malignant disease from the biopsy specimens. Surgery became unnecessary as a result of aspiration biopsy in at least 12 patients. One patient showed evidence of intrahepatic bleeding during liver biopsy but recovered spontaneously, and the liver appeared normal at laparotomy 3 weeks later. Aspiration biopsy is an accurate, relatively painless, inexpensive and safe method of establishing a diagnosis of intraabdominal malignant disease. Considerable experience of the cytologist is necessary for good results. |
