[Ultrasonically guided fine-needle biopsy of space-occupying lesions in liver]

105 patients with liver space-occupying lesions were biopsied with fine-needle guided by ultrasound. Smear cytologic examination was performed in all and histologic examination was done simultaneously in some. The diagnosis accuracy rate was 95.2%, sensitivity was 94.9%, specificity was 96.2% which were higher than those diagnosed by ultrasound only (accuracy rate 86.7%) and no complications occurred. The results of cytology, histology and both methods combined are analysed and compared. It shows that the combined examination may increase the diagnosis accuracy rate.
