Tokyo Guidelines 2018 — Acute Cholangitis Severity

Tokyo Guidelines 2018 (TG18) for grading severity of acute cholangitis to guide management decisions including timing of biliary drainage.

Cardiovascular (hypotension needing dopamine ≥ 5 µg/kg/min or any noradrenaline), neurological (disturbed consciousness), respiratory (PaO₂/FiO₂ < 300), renal (oliguria or creatinine > 2.0 mg/dL), hepatic (PT-INR > 1.5), haematological (platelets < 100 × 10⁹/L)

Score interpretation

Grade I — Mild 1

Grade I: no Grade II or III criteria at diagnosis.

→ Antibiotics; biliary drainage if there is no response to initial treatment within 24 hours; treat the cause (e.g. ERCP for stones) once settled.

Grade II — Moderate 2

Grade II: two or more of the Grade II factors, without organ dysfunction.

→ Antibiotics and early biliary drainage (endoscopic or percutaneous); close monitoring.

Grade III — Severe 3

Grade III: organ dysfunction present (cardiovascular, renal, respiratory, hepatic, haematological, neurological)

→ Organ support (ICU/HDU) and antibiotics, with urgent biliary drainage once stabilised; multidisciplinary care.

Interpretation bands for the TG18 Cholangitis. Apply clinical judgement and local guidance.
