[Is percutaneous liver biopsy using the Trucut (Travenol) needle superior to Menghini puncture?].
The aim of this study was to compare the quality of biopsy cylinders obtained by the Menghini or Trucut liver biopsy-method as well as the frequency of complications observed with both these methods. For this purpose, 74 Menghini and 62 Trucut biopsies were analyzed. Both groups were comparable with respect to histologic diagnosis, but no final diagnosis could be made in eight cases of Menghini biopsy because of insufficiency of the material obtained. Fragmentation of the sample occurred significantly more often in the Menghini group (p less than 0.05; chi 2 test). Trucut biopsies were significantly longer (12 mm versus 8 mm mean value; p less than 0.001; Wilcoxon rank sum test) and contained significantly more portal tracts (16 versus 6 mean value; p less than 0.001). None of the total 136 biopsies led to serious complications. We conclude that Trucut liver biopsy is superior to the Menghini method since tissue yield is better and both methods are equally safe.
