Tokyo Guidelines 2018 — Acute Cholecystitis Severity

Tokyo Guidelines 2018 (TG18) for grading severity of acute cholecystitis to guide timing of cholecystectomy.

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 features.

→ Early laparoscopic cholecystectomy (within 72h); IV antibiotics; low risk

Grade II — Moderate 2

Grade II: marked local inflammation — WBC >18, palpable mass, prolonged symptoms or marked local peritonitis

→ Early cholecystectomy by experienced surgeon, or percutaneous cholecystostomy if unfit; IV antibiotics

Grade III — Severe 3

Grade III: organ dysfunction present — high risk of morbidity and mortality

→ Urgent ICU care; IV antibiotics; percutaneous cholecystostomy as bridge; cholecystectomy after stabilisation

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