Insights
Early detection of biliary atresia is crucial. A national screening program using stool color cards can significantly improve diagnosis and outcomes for this serious liver disease in infants.
Area of Science:
- Pediatric Hepatology
- Neonatal Cholangiopathies
Background:
- Biliary atresia is a fatal progressive obstructive cholangiopathy if untreated within two years.
- Delayed diagnosis stems from difficulty distinguishing it from physiologic jaundice and identifying abnormal stool color.
Purpose of the Study:
- To provide an overview of biliary atresia diagnosis.
- To discuss current management strategies for biliary atresia in developing countries.
Main Methods:
- Literature search of PubMed using terms: biliary atresia, Kasai portoenterostomy, pediatric liver transplantation.
- Incorporation of authors' clinical experience.
Main Results:
- A national screening program with stool color cards can enhance early detection of biliary atresia.
- Early diagnosis, referral to specialized units, and timely Kasai portoenterostomy improve outcomes.
- Early Kasai portoenterostomy leads to survival into adolescence for nearly half of affected children, with one-third achieving long-term symptom-free lives.
Conclusions:
- Sequential treatment combining Kasai portoenterostomy and liver transplantation achieves a 90% survival rate for children with biliary atresia.
- Implementing stool color card screening as standard neonatal care is vital for early detection and improved prognosis.
Need And Purpose Of Review:
Biliary atresia is a progressive obstructive cholangiopathy and is fatal if left untreated within 2 years of life. Delay in referral is because of difficulties in differentiating it from physiologic jaundice and identifying an abnormal stool color. This paper presents an overview on the diagnosis and discusses the current strategies in the management of this disease in developing countries.
Methods:
Articles were retrieved from the PubMed database using the terms biliary atresia, Kasai portoenterostomy and pediatric liver transplantation. Contents of the article are also based on personal experience of the authors.
Conclusion:
A national screening program using stool color cards as part of standard care in the neonatal period will greatly improve early detection of biliary atresia. Outcomes will improve if it is diagnosed at the earliest after birth, the child is referred to an experienced pediatric hepatobiliary unit for evaluation, and undergoes an early Kasai procedure. If an early Kasai portoenterostomy is performed, nearly half of all children survive into adolescence, and about one-third are likely to have a long-term, symptom-free life with normal liver biochemistry. Sequential treatment combining Kasai as first line and liver transplantation as second line results in 90% survival for children with biliary atresia.
