Biliary atresia: the Brazilian experience.

Area of Science:

• Pediatric Surgery
• Hepatology
• Clinical Epidemiology

Background:

• Biliary atresia is a severe neonatal liver disease requiring timely intervention.
• Early diagnosis and surgical treatment, such as portoenterostomy, are critical for improving prognosis.
• Liver transplantation (LTx) is a life-saving option for advanced cases.

Purpose of the Study:

• To analyze the epidemiological, clinical, and prognostic factors of biliary atresia in Brazilian children.
• To evaluate the impact of surgical timing and treatment strategies on patient survival.
• To identify regional disparities in the management of biliary atresia within Brazil.

Main Methods:

• A multicenter retrospective study involving 513 children diagnosed with biliary atresia between 1982 and 2008.
• Data collected included age at portoenterostomy, liver transplantation (LTx) status, and survival outcomes.
• Patient data were analyzed across different decades of surgery and geographical regions in Brazil.

Main Results:

• Portoenterostomy was performed in 76.4% of patients, with a median age of 82.6 days; 46.6% underwent LTx.
• Survival rates significantly improved over the decades, from the 1980s to the 2000s (p < 0.001).
• Delayed portoenterostomy (>90 days) was associated with lower native liver survival (26.6%) and overall survival (60.5%).

Conclusions:

• Late referral for biliary atresia remains a significant challenge in Brazil, negatively affecting patient survival.
• Improved survival trends correlate with increased rates of liver transplantation over time.
• Developing strategies for earlier detection and referral is essential to decrease the burden of biliary atresia and the need for LTx.
