Common questions
What does Acute Cholangitis Severity & Management (TG18) do?
Use to assign TG18 severity (organ dysfunction or moderate criteria) and time biliary drainage, from urgent in Grade III to response-based in Grade I.
How is the result calculated?
Grade III = any new organ dysfunction → urgent drainage once stable. Grade II = ≥ 2 moderate criteria → early drainage. Grade I → antibiotics, drainage if no response within 24 h. ERCP preferred, PTBD if not feasible.
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
