The Tokyo Guidelines for Cholangitis
Cholangitis
Biliary infection associated with partial or complete obstruction of the biliary tree
Diagnosis based on clinical findings, such as Charcot’s triad, with laboratory data and imaging findings
Charcot’s triad- Fever- Jaundice- Abdominal pain
Reynold’s Pentad- + Hypotension- + Mental obtundation
Lai EC, Tam PC, Paterson IA, Ng MM, Fan ST, Choi TK, et al. Emergency surgery for severe acute cholangitis. The high-risk patients. Ann Surg 1990;211:55–9.
There was no standard criteria for the diagnosis and severity assessment
Tokyo guidelines
Based on a systematic review of literature and consensus of experts at the International Consensus Meeting in Tokyo 2006
TG07
A. Clinical contest and clinical manifestations
1. History of biliary disease2. Fever and/or chills3. Jaundice4. Abdominal pain (RUQ or upper
abdominal)
B. Laboratory data 5. Evidence of inflammatory response6. Abnormal liver function tests
C. Imaging findings 7. Biliary dilatation, or evidence of an etiology (stricture, stone, stent etc)
Suspected diagnosis 2 or more items in A
Definite diagnosis (1)Charcot’s triad (2+3+4)(2)Two or more items in A + both
items in B and item CDiagnostic criteria and severity assessment of acute cholangitis: Tokyo Guidelines. J Hepatobiliary Pancreat Surg (2007) 14:52–58
B-5: abnormal WBC, raised CRP and other changes indicating inflammation
B-6: raised ALP, r-GTP (GGT), AST and ALT levels
Severity assessment criteria 2007
Mild (grade I):acute cholangitis which responds to the initial medical treatment
Moderate (grade II) acute cholangitis which does not respond to the initial medical treatment and is not accompanied by organ dysfunction
TG07 Severity assessment criteria
Grade III (severe)- Associated with onset of dysfunction in at
least one of the following organs/ systems
1. Cardiovascular dysfunction Hypotension requiring dopamine >=5ug/kg per min, or any dose of norepinephrine
2. Neurological dysfunction Disturbance of consciousness
3. Respiratory dysfunction PaO2/FiO2 ratio < 300
4. Renal dysfunction Oiguria, serum creatinine > 2.0mg/dl
5. Hepatic dysfunction PT-INR > 1.5
6. Hematological dysfunction Platelet count < 100000/mm3
Because of new information, the Tokyo Guidelines Revision Committee was organized to develop the update Tokyo guidelines (TG13)
Multiple tertiary centers in JapanFrom Jan 2007 and July 2011794 patients with cholangitis
Revision of TG07
The diagnostic criteria was adjusted to achieve the highest sensitivity and specificity

TG13 diagnostic criteria
A. Systemic inflammation A-1. Fever +/- shaking chills A-2. Laboratory data: evidence of inflammatory response
B. Cholestasis B-1. Jaundice B-2. Laboratory data: abnormal liver function tests
C Imaging C-1. Biliary dilatation C-2. Evidence of etiology on imaging (stricture, stone, stent, etc)
Suspected diagnosis: one item in A + one item in either B or C
Definite diagnosis: one item in A, one item in B and one item in C

With suspected diagnosis, early biliary drainage and source control of infection can be provided
Formulation of new severity assessment
TG07 insufficient in separating Grade I and Grade II
Need 24 hour observation periodDefinition of grade II ambiguous

No significant difference in clinical outcome was observed in patients of different severity grades
Conclusion: The TG07 are more reliable than Charcot's triad for the diagnosis of acute cholangitis albeit with limited prognostic values.

Grade III: 7.6 ± 2.1 Grade II: 6.5 ± 3.0 Grade I: 2.9 ± 0.9, p < 0.001

Improved prognosis of in-hospital mortality with odds ratio of 0.856 among patients with high compliance with the TG07
Take home message
The Tokyo guidelines are more sensitive than Charcot’s triad for diagnosis of cholangitis
TG13 produces a new standard for diagnosis, severity grading and management of acute cholangitis
Awaiting further validation on TG13
