Aims Endoscopic retrograde cholangiopancreatography (ERCP) has a pivotal role in the management
of acute gallstone cholangitis (AGC), although timing is controversial. Tokyo 2018
Criteria (TC2018) allow severity categorisation, however stratifying the risk to determine
ideal “Emergency Room (ER) to ERCP time” (ER-ERCPt) is an unmet need.
Aims: To assess the utility of TC2018 in predicting clinical outcomes (intrahospital
mortality [IHM], admission to Intensive Care Unit [ICU] and length of stay [LOS]).
To identify additional predictors and evaluate the impact of ER-ERCPt on clinical
outcomes.
Methods Retrospective review of AGC admissions who met TC2018 for definite cholangitis and
underwent ERCP, from January 2015 to December 2019. TC2018 were applied retrospectively.
Results 189 patients were included (average age:74.1±13.2 years;52.6 % male), 60 of which
had mild, 84 moderate and 45 severe disease. Multivariate logistic regression analysis
showed severe AGC (odds ratio(OR):18.3;p = 0.01), C-reactive protein(CPR)≥15 mg/dL
(OR:7.1;p = 0.009) and lactate≥2 mmol/L (OR:10.5;p = 0.01) at admission as independent
risk factors for ICU admission. Median LOS was 7 days with interquartile range 2-13.
Severe AGC (p = 0.001), CPR≥15 mg/dL (p = 0.001) and lactate≥2 mmol/L (p = 0.01) were
associated with significantly longer LOS. The IHM was 2,6 % (n=5; all severe AC).
Lactate≥2 mmol/L was predictor of IHM (OR:15.7;p = 0.015). 53.3 % of severe patients
had an ER-ERCPt<48 hours(h) (moderate:20.3 %;mild 21.3 %;p = 0.01). ER-ERCPt<48h was
associated with lower LOS (p = 0.03), but not with significantly lower rate of ICU
admission and IHM. Among severe patients, ER-ERCPt<24h was significantly associated
with a greater reduction in organ failures (OF) in the first 48h of hospitalization
(OR:0.24;p = 0.04).
Conclusions Severe AGC, lactate≥2 mmol/L and CPR≥15 mg/dL are independent prognostic factors
of adverse outcomes (LOS and ICU admission). A shorter ER-ERCPt had positive impact
in reducing LOS and number of OF. Inclusion of lactate and CPR may improve the current
TC2018 with respect to risk stratification and subsequent management.
