[Ultrasonically guided percutaneous needle aspiration biopsies (author's transl)]

Abstract

Ultrasonically guided percutaneous fine needle aspiration biopsies were carried out in 179 patients with sonographically proven space occupying lesions of the liver, pancreas and kidneys as well as the retroperitoneal space. The fine needle aspiration biopsies were done using a B-scan-aspiration-biopsy transducer with a special needle having an outer diameter of 0,4--0,6 mm. Liver metastases were proven cytologically in 57/70 patients (81%), pancreatic carcinomas in 20/31 patients (64%), kidney tumours in 15/20 patients (75%), retroperitoneal lymph node metastases and primary malignant lymphomas in 20/32 patients (62%). The ultrasonically guided fine needle aspiration biopsy is simple, practically without pain, risk or complications for the patient, and is an economically feasible examination method.
