BACKGROUND: The Tokyo guidelines from 2007 (TG07) and 2013 (TG13) were compared for the management of acute cholangitis (AC).

METHODS: We reviewed patients with clinically-proven AC by detecting purulent biles during biliary drainage. TG07 and TG13 were compared regarding diagnosis, severity grading and prognostic values. New risk factors for 30-day mortality were investigated.

RESULTS: Definite diagnosis for 120 eligible patients was made in 104 (86.7%) and 101 (84.2%) cases by TG07 and TG13, respectively (P = 0.36), higher than 61 (50.8%) by Charcot's triad (P < 0.001). Diagnostic overlap and concordance (κ) are 90.8% (109/120) and 0.63 (P < 0.0001). Patients classified into mild and moderate grades by TG07 and TG13 differed significantly (P = 0.043). Both guidelines could not predict clinical outcomes except the needs for multi ERCP session by TG13. Intrahepatic obstruction (OR = 11.2, 95% CI: 1.55-226.9) and hypoalbuminemia (≤ 25.0 g/l; OR = 17.3, 95% CI: 3.5-313.6) were independent risk factors for 30-day mortality in multivariate model.

CONCLUSION: Two guidelines are reproducible and reliable in AC diagnosis but different in severity grading. TG13 are more practical for immediate severity grading, enabling planning treatment upon admission. Intrahepatic obstruction is a new candidate predictor of 30-day mortality for further assessment.
