Abstract
Using a new method of ultrasonically guided fine needle biopsy under permanent visual control, it is now possible to biopsy tumor-suspect changes of the pancreas and other abdominal organs reliably. The risk for the patient is reduced to a minimum. The method leads to considerable improvement in obtaining biopsy material, is easily performed and may be repeated. The correct diagnosis was established in 18 patients with pancreatic disease by cytological investigation. Sonographic interpretation of space occupying pancreatic lesions was successful in 16 patients.
