Is the Kasai operation still indicated in children older than 3 months diagnosed with biliary atresia?

Area of Science:

• Pediatric Surgery
• Hepatology
• Transplantation Immunology

Background:

• Biliary atresia prognosis worsens with delayed hepatoportoenterostomy (Kasai operation).
• The efficacy of the Kasai operation after 3 months of age requires further investigation.

Purpose of the Study:

• To evaluate the justification and outcomes of the Kasai operation performed after 3 months of age for biliary atresia.
• To compare survival rates based on the timing of the Kasai operation.

Main Methods:

• Retrospective review of biliary atresia patients in France (1986-1996).
• Classification into three groups: early surgery (<90 days), late surgery (>=90 days), and no Kasai operation (transplant-oriented).
• Kaplan-Meier survival analysis and log-rank tests were used.

Main Results:

• Late Kasai operation (>=90 days) showed lower 5- and 10-year native liver survival compared to early surgery (25% vs 35%).
• Overall 5-year survival was significantly better in the early surgery group (74%) versus late surgery (55%) and transplant-oriented groups (57%).
• Survival post-liver transplantation did not differ significantly across groups, with higher pre-transplant mortality in groups 1 and 3.

Conclusions:

• The Kasai operation may be beneficial in selected patients older than 3 months, potentially obviating the need for liver transplantation.
• Preoperative assessment is vital to identify patients with advanced liver disease who require timely liver transplantation.
• Delayed Kasai operation can be justified, but careful patient selection is paramount to avoid poor outcomes.
