<b><i>Background:</i></b> Acute cholangitis (AC) is a common emergency with a significant mortality risk. The Tokyo Guidelines (TG) provide recommendations for diagnosis, severity stratification, and management of AC. However, validation of the TG remains poor. This study aims to validate TG07, TG13, and TG18 criteria and identify predictors of in-hospital mortality in patients with AC. <b><i>Methods:</i></b> This is a retrospective audit of patients with a discharge diagnosis of AC in the year 2016. Demographic, clinical, investigation, management and mortality data were documented. We performed a multinomial logistic regression analysis with stepwise variable selection to identify severity predictors for in-hospital mortality. <b><i>Results:</i></b> Two hundred sixty-two patients with a median age of 75.9 years (IQR 64.8–82.8) years were included for analysis. TG13/TG18 diagnostic criteria were more sensitive than TG07 diagnostic criteria (85.1 vs. 75.2%; <i>p</i> < 0.006). The majority of the patients (<i>n</i> = 178; 67.9%) presented with abdominal pain, pyrexia (<i>n</i> = 156; 59.5%), and vomiting (<i>n</i> = 123; 46.9%). Blood cultures were positive in 95 (36.3%) patients, and 79 (83.2%) patients had monomicrobial growth. The 30-day, 90-day, and in-hospital mortality numbers were 3 (1.1%), 11 (4.2%), and 15 (5.7%), respectively. In multivariate analysis, type 2 diabetes mellitus (OR = 12.531; 95% CI 0.354–116.015; <i>p</i> = 0.026), systolic blood pressure <100 mm Hg (OR = 10.108; 95% CI 1.094–93.395; <i>p</i> = 0.041), Glasgow coma score <15 (OR = 38.16; 95% CI 1.804–807.191; <i>p</i> = 0.019), and malignancy (OR = 14.135; 95% CI 1.017–196.394; <i>p</i> = 0.049) predicted in-hospital mortality. <b><i>Conclusion:</i></b> TG13/18 diagnostic criteria are more sensitive than TG07 diagnostic criteria. Type 2 diabetes mellitus, systolic blood pressure <100 mm Hg, Glasgow coma score <15, and malignant etiology predict in-hospital mortality in patients with AC. These predictors could be considered in acute stratification and treatment of patients with AC.
Aim of the study This study aims to validate Tokyo guidelines (TG) TG07/TG13/TG18 criteria and identify predictors of in-hospital mortality in acute cholangitis (AC) patients over 80 years old. Material and methods This is a retrospective audit of AC patients from January 2009 to December 2016. Demographic, clinical, investigation, management, and mortality data were studied. Multinomial logistic regression analysis with stepwise variable selection identified predictors for in-hospital mortality. Results Three hundred and eighty-eight patients were treated for AC. One hundred and sixty-two (41.8%) patients were male. 230 (59.3%) patients had a history of biliary disease, 161 (41.5%) patients had type 2 diabetes mellitus (T2DM), and 98 (25.3%) patients had ischaemic heart disease (IHD). Abdominal pain ( n = 226, 58.2%), pyrexia ( n = 247, 63.7%), and vomiting ( n = 159, 41.0%) were the common presenting symptoms. 191 (49.2%) patients had abdominal tenderness. Positive blood cultures were recorded in patients 158 (40.7%) patients. Escherichia coli was the most commonly identified organism ( n = 117, 30.2%). 77 (19.8%), 188 (48.5%) and 123 (31.7%) patients were graded with mild, moderate, and severe AC, respectively. 30-day, 90-day, and in-hospital mortality were 9 (2.3%), 19 (4.9%) and 38 (9.8%), respectively. On multivariate analysis, systolic blood pressure ≤ 100 mmHg (OR = 3.817, 95% CI: 1.365-10.761, p = 0.011), hypoalbuminaemia < 28 gm/l (OR = 6.052, 95% CI: 2.635-13.904, p < 0.001), serum creatinine ≥ 176.8 (OR = 2.787, 95% CI: 1.146-6.778, p = 0.024) and international normalized ratio (INR) > 1.5 (OR = 3.247, 95% CI: 1.234-8.544, p = 0.017) were independent predictors of in-hospital mortality. Conclusions Hypotension, hypoalbuminaemia, elevated creatinine, and elevated INR predict in-hospital mortality in AC patients over 80 years old.
