    Tokyo Guidelines for Acute Cholangitis 2018

    Provides diagnostic criteria and severity grading for acute cholangitis.
    When to Use
    Pearls/Pitfalls
    Why Use

    Use in patients with suspected acute cholangitis (i.e., fever, jaundice, right upper quadrant pain, altered mental status, and/or hemodynamic instability).

    • More extensively studied in non-US populations.

    • Conditions such as acute hepatitis and acute cholecystitis may have some similarities in presentation and should be ruled out.

    • Although MRI and MRCP have the highest sensitivity/specificity for bile duct dilation, abdominal US followed by CT abdomen are more readily available and cost-effective, and thus should be performed initially.

    • Procalcitonin is useful in assessing the severity of cholangitis, not in the diagnosis.

    • For patients with grade II-III (moderate to severe) cholangitis, transfer to a hospital that can perform biliary drainage and provide ICU level care is recommended.

    • Objectively guides diagnosis and management of patients with acute cholangitis in terms of timing and need for biliary drainage and supportive care.

    • Charcot’s triad (fever, right upper quadrant pain, jaundice) has high specificity but low sensitivity for acute cholangitis (Kiriyama et al 2017).
