BACKGROUND: Biliary drainage via endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for acute cholangitis. Despite the established effectiveness of urgent biliary drainage in patients with severe acute cholangitis, the indication of this procedure for non-severe acute cholangitis is controversial. AIMS: To assess the safety of elective drainage (≥ 12 h of admission) for non-severe acute cholangitis. METHODS: We retrospectively identified 461 patients with non-severe acute cholangitis who underwent endoscopic biliary drainage. Using linear regression models with adjustment for a variety of potential confounders, we compared elective versus urgent biliary drainage (< 12 h of admission) in terms of clinical outcomes. The primary outcome was the length of stay. RESULTS: There were 98 and 201 patients who underwent elective and urgent biliary drainage, respectively. The median length of stay was 11 days in both groups (P = 0.52). The timing of ERCP was not associated with length of stay in the multivariable model (P = 0.52). Secondary outcomes including in-hospital mortality and recurrence of cholangitis were not different between the groups. CONCLUSIONS: Elective biliary drainage was not associated with worse clinical outcomes of non-severe acute cholangitis as compared to urgent drainage. Further investigation is warranted to justify the elective drainage for non-severe cholangitis.
