ABSTRACT To determine whether portoenterostomy (PE) revision in patients afflicted with biliary atresia (BA) is a viable treatment option and, if so, identify which patients may benefit.
BA, the most common cause of neonatal liver disease, results in biliary tract obstruction and hepatic fibrosis. Kasai PE is the initial surgical intervention performed and, if successful, restores drainage and preserves the native liver. Portoenterostomy failure warrants liver transplantation, but because of complications related to transplantation, treatment strategies to salvage the native liver may be beneficial. Using uniformly applied criteria, we have revised PEs to delay or avoid transplantation.
A retrospective review of medical records of patients diagnosed with BA since 1983 was performed. Patient demographics, symptoms, indications for revision, laboratory values, and outcomes were recorded. A cohort of patients who underwent revision after initial PE was identified. Survival rates were assessed using the Kaplan-Meier method. For patients who required transplantation, operative data from the revised PE cohort were compared with those from the unrevised PE cohort. A Cox proportional hazards model was used to determine covariates predictive of a favorable outcome.
Of 181 children who underwent PE, 24 underwent revision. Adequate biliary drainage, as evidenced by normalized conjugated bilirubin levels, was achieved in 75% of revised patients. Overall survival in patients who underwent revision, regardless of transplantation, was 87%. Among patients who underwent PE revision, 46% have survived with their native liver.
Experience at our center suggests that with appropriate patient selection, PE revision may delay the need for liver transplanation yielding encouraging patient outcomes.

    ABSTRACT: This study was conducted to reappraise the efficacy of redo-Kasai (or revision) in the era of liver transplantation as a treatment option in those patients with recurrent jaundice after initially successful Kasai procedure. We studied ten patients that received redo-Kasai, among a total of 102 patients diagnosed with biliary atresia after receiving Kasai operation from 1986 to 2011. Kasai operation was done at a median age of 55 days and redo-Kasai at 150 days. The bilirubin levels returned to normal in six patients after the procedure. Four of six enjoyed jaundice-free survival with native liver till the time of last follow-up. Three patients died and three received liver transplantation (LT). Only one out of seven patients with three or more episodes of cholangitis survived with native liver, while all the three patients with 1 or 0 episode survived with native liver. The difference was significant (P = 0.033). Re-do Kasai did not result in more blood loss or operative time during LT. Redo-Kasai is still valuable in the era of LT and the episodes of cholangitis are the decisive factors affecting the outcome of the procedure.
