[Needle puncture biopsy: the contribution of extemporaneous examination of samples in the diagnosis of malignant liver tumors].
In this retrospective study, the authors compared the sensitivity and specificity, in terms of the diagnosis of malignancy, of two techniques of ultrasound-guided biopsy of liver tumours. The first technique involving fine needle biopsy with cytological and histological analysis of the specimen was carried out in 39 patients. A technique using a wide calibre needle with frozen section examination of the fragment obtained was performed in 27 patients. All patients had one or more malignant liver tumours. Sensitivity and specificity of the technique with frozen section histology were both 100 per cent, while figures for the technique with delayed histological study were 84.6 and 87.4 per cent. This study suggests that frozen section histology might be associated with greater sensitivity than delayed histology.
