ABSTRACT

INTRODUCTION: Guidelines recommend early endoscopic retrograde cholangiopancreatography for the management of acute cholangitis, but the definition of the term "early" remains debatable. This study analyzed national trends in the timing of endoscopic retrograde cholangiopancreatography and identified the ideal time to perform preoperative endoscopic retrograde cholangiopancreatography in patients with acute cholangitis.

METHODS: The 2005 to 2016 National Inpatient Sample was used to identify patients undergoing cholecystectomy for acute cholangitis. Severity of cholangitis was defined using the 2013 Tokyo Grading Criteria, where Tokyo grade III patients were defined as having organ dysfunction and non-Tokyo grade III patients were defined as grades I and II. Multivariable regressions (accounting for patient and hospital characteristics) were used to identify the timing of preoperative endoscopic retrograde cholangiopancreatography associated with the least mortality risk.

RESULTS: Of 91,051 patients undergoing cholecystectomy for cholangitis, 55% underwent preoperative endoscopic retrograde cholangiopancreatography: 24% of patients received endoscopic retrograde cholangiopancreatography on the day of admission, 41% on hospital day 2, and the use of endoscopic retrograde cholangiopancreatography decreased gradually thereafter. Mortality rates remained under 1% if endoscopic retrograde cholangiopancreatography was performed during the first 3 days and increased as endoscopic retrograde cholangiopancreatography was performed during days 4 to 7 (P < .001). On multivariable regression, endoscopic retrograde cholangiopancreatography performed >72 hours after admission was associated with increased mortality (adjusted odds ratio 1.80, P = .01). Receiving endoscopic retrograde cholangiopancreatography P > 72 hours increased risk of death among Tokyo grade III patients (adjusted odds ratio 1.88, P = .01). Overall, during the study period, the utilization of preoperative endoscopic retrograde cholangiopancreatography for all grades of acute cholangitis increased from 39% of patients in 2005 to 51% in 2016 (P < .001).

CONCLUSION: There has been an increase in the use of endoscopic retrograde cholangiopancreatography for acute cholangitis. Although endoscopic retrograde cholangiopancreatography on the day of admission was not associated with a decrease in mortality in patients with Tokyo grade III disease, endoscopic retrograde cholangiopancreatography within 72 hours of hospitalization was associated with decreased in-hospital mortality.
