Histological evolution of fibrosis in patients with biliary atresia
| Resumo: | ABSTRACT Objective: To evaluate the evolution of histological findings of patients with biliary atresia (BA), emphasizing the progression of fibrosis by comparing the diagnostic liver biopsy to the surgical liver biopsy, performed during Kasai portoenterostomy. Methods: Retrospective study with 51 patients with BA submitted to portoenterostomy, and both diagnostic (DLB) and surgical liver biopsies (SLB). The samples were blindly reviewed by two pathologists. Results: Median age at DLB and at SLB was 69 and 77 days, respectively. The median time between biopsies was eight days. Cirrhosis was more frequent in SLB than in DLB, both according to the Metavir score (p = 0.006) and the Ishak score (p = 0.016). The Metavir score increased one or more points in 29/51 (56.9%), with evidence of progression to liver cirrhosis in 11/29 (37.9%) of those who had progression of fibrosis. Median age at surgery of those who had a progression of fibrosis was 77 days, while in those 11 who progressed to cirrhosis, this median was 92 days. Cirrhosis was seen in 12/51 (23.5%) SLB patients. The clinical variable age at surgery had a statistically significant difference regarding the presence or absence of cirrhosis in SLB (p = 0.024). Cirrhosis was not related to survival with native liver or biliary drainage. Conclusion: Most infants with BA have liver fibrosis at diagnosis and it progresses rapidly. The presence of cirrhosis is correlated with the age at surgery, which suggests the importance of this clinical variable in the evolution of fibrosis. |
