Risk Prediction Scoring System to Predict the Postsurgical Outcomes of Biliary Atresia.

Area of Science:

• Pediatric Surgery
• Hepatology
• Gastroenterology

Background:

• Biliary atresia (BA) is a severe neonatal liver disease requiring timely surgical intervention.
• Kasai Portoenterostomy (KPE) is the primary surgical procedure for BA, but outcomes vary.
• Predicting KPE success is crucial for patient management and prognosis.

Purpose of the Study:

• To investigate the association between liver function, liver histopathology, and outcomes following KPE in biliary atresia.
• To develop a predictive scoring system for successful KPE outcomes.

Main Methods:

• Retrospective analysis of 26 pediatric patients who underwent KPE.
• Collected data included liver function tests (bilirubin, AST, ALT, GGT), coagulation profile, and histopathology (fibrosis grade, bile ductular size).
• Statistical analysis identified significant parameters and developed a risk prediction model using Receiver Operating Characteristic (ROC) curves.

Main Results:

• The ratio of Aspartate transaminase (AST) to Alanine transaminase (ALT), AST to Platelet Ratio Index (APRi), and fibrosis grade were statistically significant predictors of KPE success.
• A combination of AST/ALT ratio < 2.1, APRi < 1.8, and fibrosis grade < 4 predicted successful KPE with 96.2% probability.
• A novel scoring system and risk prediction model were constructed.

Conclusions:

• The developed scoring system and risk prediction model can effectively guide the management and post-operative follow-up of children with biliary atresia.
• Further validation in a prospective trial is intended.
• The model suggests KPE for patients with a score < 7 and consideration for those with scores between 8 and 16 out of 20.
