Age Is Not a Criterion in Patient Selection for Kasai Portoenterostomy.

ABSTRACT

AIMS: The aim of our study was to compare the outcome of Kasai portoenterostomy (KPE) in children with biliary atresia (BA) older than 90 days to children less than 90 days and to study its safety and efficacy in children older than 90 days. SUBJECTS AND METHODS: Relevant data were collected from our prospectively maintained database of all children with BA who underwent KPE over a 5-year period. Children were divided into two groups Group 1 ≤90 days and Group 2 >90 days. Data analyzed and compared included total and direct bilirubin, aspartate aminotransferase-to-platelet ratio index (APRI), and the outcome of procedure which was defined as a serum direct bilirubin <2 mg/dl within 6 months after surgery. Standard statistical tests were used for analysis. RESULTS: Out of 62 children, 45 children were in Group 1 and 17 children were in Group 2. Children in Group 2 had similar total and direct bilirubin compared to children in Group 1. APRI, an indicator of fibrosis, was significantly increased in Group 2 (P = 0.08). About 47% of children in Group 2 had Stage III fibrosis on liver histology compared to 22% of children in Group 1. None of the children in Group 2 had synthetic liver failure (refractory ascites, hypoalbuminemia, or coagulopathy unresponsive to Vitamin K) or portal hypertension. KPE was successful in 29.4% of children in Group 2 and 44% in children in Group 1. There was no perioperative mortality in our group. CONCLUSIONS: KPE was successful in a third of children over 90 days of age and can be safely performed in this group. In the absence of synthetic liver failure, age should not be a disqualification for performing KPE.
