    Abstract:
    Percutaneous needle sampling of malignant tumors carried out by fine-needle cytologic aspiration and large-needle cutting techniques both possess certain limitations. A fine caliber 22 gauge cutting needle and a modified sampling technique used in 78 patients with suspected abdominal neoplasms are described. Both cytologic and histologic samples were sought in each case and overall successful diagnoses were made in 88% of 50 proved cases, with specific histologic diagnoses in 56%. Cytologic specimens were more sensitive in 14 cases in the detection of malignancy, while histologic results were more specific in nine cases. No significant complications were encountered. This modified method has not replaced the former cytologic aspiration technique in this institution.
