Ratio of Preoperative and Postoperative Serum Bilirubin Levels Predicts Early Outcome Following Biliary Atresia Surgery
Overview
Affiliations
Aim: This study investigates the fall in total serum bilirubin levels within 1 week after surgery, as a marker to predict early outcome in biliary atresia (BA) patients post-Kasai portoenterostomy (KP).
Methods: The ratio of total serum bilirubin levels at the 7 postoperative day to the preoperative level (TB7/TB0) in patients undergoing KP was calculated (January 2011-July 2015). Patients were stratified after 3-months follow-up into outcome groups depending on the clinical clearance of jaundice and TB7/TB0 ratio was correlated to outcome and liver histopathological changes in these groups.
Results: Sixty-one patients (M:F = 44:17), median age 75 days were included. At the end of 3 months, 27 (44.39%) were anicteric while 26 (42.6%) were still clinically jaundiced. Patients with a higher median value of TB7/TB0, that is, 0.856 were more likely to have jaundice at the end of 3 months as compared to patients with a lower median value of 0.615 ( < 0.0001). A cutoff TB7/TB0 ratio >0.723 predicted the KP outcome with 84.6% sensitivity and 81.5% specificity. The difference in TB7/TB0 ratio between patients with varying severity of liver histopathological changes was also significant, namely, cholestasis ( = 0.01), hepatocellular damage ( = 0.03), portal inflammation ( = 0.04), and portal fibrosis ( = 0.02).
Conclusions: The rapidity of fall in the total serum bilirubin levels within 1 week post-KP was able to predict the likely outcome in BA patients.
