ARTICLE HIGHLIGHTS
Research background

Acute cholangitis is associated with a high mortality when the diagnosis and treatment is delayed. After the diagnosis is made, the most common method for source control is endoscopic retrograde cholangiopancreatography (ERCP). The exact timing of ERCP and its outcomes remains unclear.

Research motivation

The recent 2018 Tokyo guidelines suggest “early” ERCP for mild cholangitis, and “urgent” ERCP for severe cholangitis with no clear defining parameters.

Research objectives

The objectives of this study was to determine the effect of early ERCP vs late ERCP on mortality and readmissions in a large nationally representative sample with acute cholangitis. This could help determine the optimal timing for ERCP as a guide to practicing clinicians.

Research methods

We used the 2014 National Readmissions Database to identify patients hospitalized with acute cholangitis. Early ERCP was defined as ERCP performed < 48 h from admission, and late ERCP was defined as ERCP performed > 48 h. Multivariate logistic regression was used to calculate the adjusted odds of association of ERCP timing with in-hospital mortality, 30-d mortality, and 30-d readmissions, controlling for age, sex, severe disease and comorbidities.

Research results

Four thousand five hundred and ninety-two patients satisfied the inclusion criteria; 65.9% had early ERCP, while 34.1% had late ERCP. Early ERCP was associated with lower in-hospital mortality (1.2% vs 2.4%) adjusted odds ratio (aOR), lower 30-d mortality (1.5% vs 3.3%), and a lower 30-d readmission rate (9.7% vs 15.1%). When stratified by severity of cholangitis, there was a similar benefit.

Research conclusion

There is a clear benefit from performing an early ERCP, specifically < 48 h from admission, for biliary drainage in patients with acute cholangitis regardless of severity. The benefits include, lower in-hospital mortality, 30-d mortality, 30-d readmission and reduced hospitalization costs.

Research prospective

Early ERCP seems to offer a mortality benefit compared to later ERCP. This data adds to the body of evidence from other studies about the benefit of early ERCP. Therefore hospitals should have the resources to perform ERCP early in patients with cholangitis, regardless of severity.
