Evaluation of Charcot Triad, Reynolds Pentad, and Tokyo Guidelines for Diagnosis of Cholangitis Secondary to Choledocholithiasis Across Patient Age Groups

Abstract

Objective: To determine the prevalence of Charcot triad, Reynolds pentad, and Tokyo Guidelines criteria and clinical outcomes among patients with cholangitis across different age groups. Patients and Methods: We conducted a retrospective analysis of 257 consecutive hospitalized adult patients with acute cholangitis due to endoscopic retrograde cholangiopancreatography–confirmed choledocholithiasis between January 1, 2015, and December 31, 2019. Patients were divided into 3 age groups: less than 65 years, 65 to 79 years, and 80 years or older. Symptoms, vital signs, and laboratory data on admission were collected. Outcomes included length of hospitalization, intensive care unit stay, and 3-month mortality. Nominal variables were tested with the Pearson χ2 test, and continuous variables were tested with the Wilcoxon rank sum test. Results: Charcot triad decreased with older ages. In the group that was age 80 years or older, malaise was the most common symptom; 33.6% (37 of 110) presented with altered sensorium, 9.1% (10 of 110) had no pain, fever, or jaundice, and positive blood culture results were more frequent. Tokyo cholestasis criterion was present in 96.0% (247 of 257), while inflammation (considered essential for diagnosis) was present in 75.9% (195 of 257). Patients 80 years or older had significantly higher mean length of hospital stay (P<.001) and mean length of intensive care unit stay (P=.021). Conclusion: Compared with patients in younger age groups, patients with cholangitis who are 80 years or older are less likely to have Charcot triad, are more likely to have features of Reynolds pentad, or present with unexplained malaise. Within the Tokyo Guidelines, cholestasis should replace inflammation as an essential diagnostic criterion.
