Summary Background : Although fragmentation of a liver biopsy specimen has been considered to be suggestive of cirrhosis, the evidence for this is difficult to find in the published literature. Aim : To determine whether fragmentation of percutaneous liver biopsy specimens correlates with the degree of fibrosis. Methods : One hundred and eighty‐six patients underwent percutaneous liver biopsy prospectively. The specimens were measured for the length and number of fragments. The extent of fibrosis was scored by a pathologist blind to the clinical data. Length and fragmentation data were compared between the different stages. Results : The overall median fragment length was 1.85 cm and the median fragment number was four. Specimens with advanced fibrosis (stages III–IV) had more fragments than those with no or mild fibrosis (stages 0–II) ( P < 0.0001). The aggregate fragment length decreased with increasing stage of fibrosis ( P < 0.0001). Specimens with greater than 12 fragments were seen only with advanced fibrosis. Conclusions : Fragmentation of percutaneous liver biopsy specimens is common and increases with progression from early to advanced fibrosis. Fibrotic specimens fragment more often and more extensively.
