A recent retrospective study (PC Hopkins, N Yazigi, CM Nylund. J Pediatr 2017; 187: 253-7) provides an update on the recent incidence of biliary atresia in the US from 1997-2012. This study relied on coding for biliary atresia or Kasai hepatoportoenterostomy to identify cases using HCUP-KID database. This database provides a nationally representative sample of pediatric hospitalizations and captures ~96% of pediatric hospitalizations in the US.
Key findings:
- Incidence of biliary atresia (BA) was 4.47 per 100,000 (1 in 22,371 infants)
- BA was more common in females (RR 1.43), Asian/Pacific Islanders (RR 1.89), and blacks (RR 1.30)
- Median age at the time of the Kasai procedure was 63 days with no improvement over the course of the study period. More than 50% of all children underwent the Kasai procedure after the optimal window of 60 days of life
My take: In my view, at this time, obtaining a blood test for direct bilirubin in the first two weeks of life will need to be adopted broadly if we are going to diagnose biliary atresia at an earlier age.
