Long-term prognosis and risk factors associated with 30-day unplanned repeated ERCP in patients with common bile duct stones

Abstract Background: The unplanned repeated endoscopic retrograde cholangiopancreatography (ERCP) in patients with common bile duct stone (CBDS) remains unclear. Objectives: To identify risk factors of unplanned repeated ERCP and its impact on clinical outcomes. Design: Retrospective cohort study. Methods: Patients who underwent ERCP for CBDSs from January 2013 to October 2023 were consecutively reviewed. Risk factors for unplanned repeated ERCP within 1 month were evaluated using logistic regression. The impact of unplanned repeated ERCP on adverse events, including ampullary bleeding,
