Comparison between wedge and needle biopsies for evaluating the degree of cirrhosis

J Hepatol. 1993 Feb;17(2):215-9. doi: 10.1016/s0168-8278(05)80041-8.


To examine whether the biopsy method could affect histological evaluation, the volumetric ratio of human liver parenchyma was estimated in specimens from subcapsular and intralobar areas, and also in specimens obtained by needle biopsy (Tru-Cut needle). A new method of morphometric analysis was performed using a computer-aided color image analyzer. Eighteen cirrhotic, 7 fibrotic, and 4 normal liver biopsies were taken during hepatic resection and analyzed. The parenchymal cell volume ratio in the intralobar area was significantly correlated with that in the subcapsular area, and less significantly with needle biopsy samples (r = 0.844, p < 0.001; r = 0.577, p < 0.01, respectively). Both showed one-to-one correspondence. These results suggest that both wedged and needle biopsy samples are appropriate for assessing the degree of fibrosis or cirrhosis, although the sampling variability of the latter is greater than the former.
