During a period of three years, 51 patients with focal hepatic changes were submitted to 55 ultrasonically guided Biopty-biopsies. Histological diagnoses could be established in 45 patients at the first biopsy which corresponds to a diagnostic certainty of 88.2% Histological diagnoses were established in 49 patients which corresponds to a certainty of 96%. The frequency of complications was 3.9%. Biopty-biopsy is recommended as a good method because it is easy to carry out and provides just as good results as other methods of biopsy.
