Biliary atresia, cytomegalovirus, and age at referral.

Abstract

CMV infection is present in an unexpectedly large proportion of patients with EHBA at the time of referral. The establishment of CMV infection in infants with cholestasis should not deter the search for EHBA. Physicians should strive to reduce the age of referral of patients with EHBA to pediatric surgical centers by evaluating infants who remained jaundiced at 4 weeks of age.
