CRITICAL CARE Liver function test abnormalities after traumatic brain injury: is hepato-biliary ultrasound a sensitive diagnostic tool?

Editor’s key points † Abnormal liver function test results are common among intensive care unit patients with traumatic brain injury. † This often occurs in the absence of any pre-existing liver dysfunction. † Hepato-biliary ultrasound scans are frequently requested to exclude treatable causes. † The authors assessed the diagnostic yield of scans performed for this reason. Background. This study was to evaluate the usefulness of hepato-biliary ultrasound (HBUS) for the investigation of isolated liver function tests (LFTs) abnormalities.
