Abstract BACKGROUND: Although experts have demonstrated the efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in cholangitis, the effectiveness of ERCP in unselected patients has not been measured. The aim was to investigate the clinical impact of ERCP performed at any time and of early ERCP (within 24 hours of admission) in patients with a primary discharge diagnosis of cholangitis. METHODS: A retrospective record review of patients admitted to eight area hospitals with an International Classification of Diseases (ICD)-9 diagnosis consistent with cholangitis was performed. Extracted data included clinical characteristics, ERCP findings, and patient outcome. The associations of ERCP overall and early ERCP with length of stay were examined. Confounding factors including severity of illness, etiology of cholangitis, and hospital type were adjusted for in a multivariate analysis. RESULTS: A total of 116 patients were studied. ERCP was performed in 71 patients with endoscopic therapy administered in 57 (80\%). ERCP overall was not associated with any change in length of hospital stay. However, compared with other invasive biliary procedures, ERCP was associated with a shorter hospital stay (median 5 vs. 9.5 days, p = 0.01) and a 36\% (95\% CI [5\%, 57\%]) reduction in severity-adjusted length of stay. Patients who had early ERCP had a significantly shorter hospital stay than those who had delayed ERCP (median 4 vs. 7 days, p < 0.005) and early ERCP was associated with a 34\% (95\% CI [11\%, 48\%]) reduction in severity-adjusted length of stay. CONCLUSION: Early ERCP may be an effective strategy for shortening the length of stay in patients hospitalized with cholangitis.
