Fine needle trucut biopsy of focal liver lesions: a new technique.
A series of 77 ultrasound guided biopsies were performed in 72 patients with an ultrasonographically diagnosed focal liver lesion using a new semiautomated biopsy gun (Temno Biopty Gun) with a 21 G trucut needle. The rate of insufficient sampling was very low (1.5%), and more precise identification of malignant as well as benign lesions was possible when compared with the results of other fine-needle techniques available in the literature. No higher complication rate was noted. Our results show a sensitivity of 88%, a specificity of 100%, and an overall accuracy of 91% in identifying malignancy. Therefore we conclude that fine-needle trucut biopsy is a safe and accurate procedure combining the safety of the fine needle with the better sample quality of a large-bore needle biopsy technique.
