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

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

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

New diagnostic criteria and severity assessment of acute cholangitis in revised Tokyo guidelines. J Hepatobiliary Pancreat Sci (2012) 19:548–556

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

A-2: abnormal WBC, raised CRP and other changes indicating inflammation

B-2: raised ALP, r-GTP (GGT), AST and ALT levels

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

TG13 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

Grade II ( moderate )- Any 2 of the following

1. Abnormal WBC count (>12000/mm3, < 4000/mm3)

2. High fever (>=39C)

3. Age (>=75 years)

4. Hyperbilirubinemia (total bilirubin >=5 mg/ dl)

5. Hypoalbuminemia (< STD x 0.7)

Grade I (mild)- Does not meet criteria for Grade II or Grade

III at initial diagnosis

Tokyo guidelines

Minimal recognition outside JapanSeveral retrospective studies have validated its

diagnostic value

Verification of the Tokyo guidelines for acute cholangitis secondary to benign and malignant biliary obstruction: experience from a Chinese tertiary hospital. Hepatobiliary Pancreat Dis Int, Vol 12, No 4, August 1, 2013.

Tokyo guidelines 2007

Based on Japanese studies- Sensitivity: 63.9-94% - Charcot’s triad < 40%

Accuracy of the Tokyo Guidelines for the diagnosis of acute cholangitis and

cholecystitis taking into consideration the clinical practice pattern in Japan. J

Tokyo guidelines 2007

Classification into mild or moderate grade using the Tokyo Guidelines is difficult when early biliary drainage is routinely performed.

Journal of Hepato-Biliary-Pancreatic Sci, July 2012, Volume 19, Issue 4, pp 487-491. Verification of Tokyo Guidelines for diagnosis and management of acute cholangitis

“Verification of the Tokyo guidelines for acute cholangitis secondary to benign and malignant biliary obstruction: experience from a Chinese tertiary hospital”

First study to verify the application of TG07 for diagnosis and treatment of cholangitis in Chinese patients

At Chinese PLA General Hospital, Beijing120 patients 82 benign; 38 malignantRetrospective from ERCP database

Definite diagnosis - 68 (82.9%) benign patients- 36 (94.7%) malignant- 104 (86.7%) overall

Charcot’s triad- 61 (50.8%) overall

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.

Compliance

60842 acute cholangitis patients from the Japanese administrative database associated with the Diagnosis Procedure Combination (DPC) system.

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

(score 0 = 0% to score 10 = 100%)Evaluation of compliance with the Tokyo Guidelines for the management of acute cholangitis based on the Japanese administrative database associated with the Diagnosis Procedure Combination system. Journal of Hepato-Biliary-Pancreatic Sciences, January 2011, Volume 18, Issue 1, pp 53-59

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
