Tokyo Guidelines 2018 — Acute Cholecystitis Severity
Tokyo Guidelines 2018 (TG18) for grading severity of acute cholecystitis to guide timing of cholecystectomy.
Score interpretation
Grade I: mild acute cholecystitis — no organ dysfunction or moderate features
→ Early laparoscopic cholecystectomy (within 72h); IV antibiotics; low risk
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: 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.
