Revision Kasai portoenterostomy: A review of indications and outcomes.

The Kasai portoenterostomy (KPE) can provide a surgical cure for children with biliary atresia (BA), without the need for a liver transplant (OLTxp). Revision KPE can be attempted following a failed initial KPE where biliary clearance is not achieved. The most common indications for revision KPE are recurrent jaundice or recurrent cholangitis, although it has also been performed for persistent jaundice or bile lakes. Outcomes are heterogenous but the best results appear to be with recurrent jaundice or limited episodes of recurrent cholangitis. In the setting of a failed KPE, providers must make a patient-specific decision about whether to attempt revision KPE versus proceed with OLTxp. While the choice is multifactorial, patients who undergo revision KPE likely do not have worse long-term outcomes than patients who undergo a single KPE.
