Persistent Ketamine-Induced Cholangiopathy: An Approach to Management.

A 32-year-old man presented with profound jaundice, rigors and decreased appetite. Initial liver function tests (LFTs) were deranged in a cholestatic pattern with imaging demonstrating a dilated biliary system, with no filling defects. It has been observed that LFTs typically improve upon ketamine cessation, but this case demonstrated escalating hyperbilirubinaemia, despite ketamine cessation. Recurrent cholangitis and biliary duct stricturing were demonstrated on magnetic resonance cholangiopancreatography (MRCP). This prompted investigation of other biliary pathology and consideration for intervention.
