[Ultrasonically guided biopsy of intra-abdominal changes. Report of the results of a 5-year study]

Ultrasound guided biopsies of intraabdominal changes have been performed in 215 patients within a five-year period. The most frequent pathologic changes were liver neoplasms--liver metastases in 51 patients, angiomas in 16 and primary carcinomas in 17. The most frequent extrahepatic pathologic changes were pancreatic diseases in 22 patients and colonic carcinomas in 17 patients. This method of biopsy enables most rapid and reliable diagnosis and it is also simple and safe.
