Study of Temporary Biliary Stenting to Prevent Cholangitis After Endoscopic Treatment of Common Bile Duct Stones

Basic Information

Recruitment status Pending
Health condition(s) or Problem(s) studiedCommon bile duct stones without acute cholangitis undergoing complete stone removal by ERCP
Date of first enrollment13/05/2026
Target sample size186
Countries of recruitment
Study typeInterventional
Intervention(s)Patients who undergo complete common bile duct stone removal by ERCP will be randomly assigned to either prophylactic biliary stenting or no stenting. In the intervention group, a spontaneously dislodging plastic biliary stent (BIT stent) will be placed immediately after ERCP for temporary biliary drainage. In the control group, no biliary stent will be placed after ERCP, and patients will receive standard post-ERCP management.

Outcome(s)

Primary OutcomeIncidence of post-ERCP cholangitis within 1-7 days after ERCP based on modified TG18 criteria
Secondary OutcomeSeverity of post ERCP cholangitis Time to onset of post ERCP cholangitis Proportion of patients requiring therapeutic antibiotic treatment after ERCP Proportion of patients requiring repeat ERCP or biliary drainage after ERCP Length of hospital stay after ERCP Incidence of ERCP related adverse events Revisit or readmission rate within 30 days after ERCP
