No Association of Timing of Endoscopic Biliary Drainage with Clinical Outcomes in Patients with Non-severe Acute Cholangitis

摘要

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 (
