Treatment of intractable cholangitis in children with biliary atresia: Impact on outcome.

Abstract

To evaluate the response and outcome with prolonged intravenous antibiotics including home-based intravenous antibiotics in children with intractable cholangitis (IC) after Kasai portoenterostomy (KPE) for biliary atresia (BA). A retrospective review of treatment and outcome of children with IC post KPE (no resolution after fourweeks of antibiotics) was donebetween 2014 and 2020. A protocol-based antibiotic regimen was used based on sensitivity and hospital antibiogram. Children afebrile for more than threedays were discharged on home intravenous antibiotics (HIVA). Twenty children with IC were managed with prolonged antibiotic regimen, including HIVA. All patients were initially listed for liver transplantation (LT) with indication being IC (n = 20) with portal hypertension (n = 12). Seven patients had bile lakes of which four underwent percutaneous transhepatic biliary drainage. Bile culture grew Klebsiella in four and Escherichia coli and Pseudomonas one each. There were eight children with IC who had positive blood culture with most of these organisms being gram-negative (Escherichia coli: 5, Klebsiella pneumoniae: 2, Enterococcus: 1). Median duration of antibiotics was 58days (interquartile range [IQR] 56-84). Median follow-up period post cholangitis was threeyears (IQR 2-4). Following treatment, 14 patients were successfully delisted from LT waitlist and are presently jaundice-free. Two of the five patients undergoing LT died of sepsis. One patient died awaiting LT. Timely and aggressive step-up antibiotic regimen may successfully treat IC and prevent/delay LT. HIVA provides a cost-effective and comfortable environment for a child which might improve compliance with intravenous antibiotics.
