Indomethacin for Biliary ERCP Patients
Indomethacin vs. no Indomethacin for Patients Undergoing Biliary ERCP With Prior Biliary Sphincterotomy
This study is a randomized clinical trial evaluating the efficacy of rectal indomethacin in preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in patients undergoing biliary ERCP who have a history of prior biliary sphincterotomy. While rectal indomethacin has demonstrated benefits in preventing post-ERCP pancreatitis in high-risk patients, its utility in this specific patient subgroup remains unclear. This trial aims to determine whether prophylactic administration of indomethacin offers a measurable benefit over no intervention in this lower-risk population.
Eligible patients will be identified prior to their scheduled biliary ERCP and screened for inclusion criteria. Following informed consent, participants will be randomized to receive either rectal indomethacin or no indomethacin prior to the procedure.

설명
Inclusion Criteria:
- Male or female ≥ 18 years of age at the time of ERCP.
- Scheduled to undergo routine biliary ERCP with documentation of a prior biliary sphincterotomy.
- Ability to receive rectal medication.
- Ability and willingness to comply with all study procedures and follow-up requirements.
- Written informed consent (and assent when applicable) was obtained from the subject or the subject's legal representative, and the subject's ability to comply with the requirements of the study was confirmed.
Exclusion Criteria:
- Pregnant, breastfeeding, or unwilling to practice birth control during participation in the study.
- Known hypersensitivity or contraindication to indomethacin, other nonsteroidal anti-inflammatory drugs, or suppository components.
- Active gastrointestinal bleeding, history of NSAID-induced gastrointestinal ulceration, or other conditions that contraindicate NSAID use.
- Significant renal impairment (e.g., baseline serum creatinine above institutional upper limit of normal or estimated glomerular filtration rate < 30 mL/min/1.73 m²).
- Current use of other NSAIDs that cannot be safely discontinued per the investigator's judgment.

Incidence of Post-ERCP Pancreatitis
기간: Within 30 days following ERCP Procedure
|
The incidence of post-ERCP pancreatitis (PEP) following biliary ERCP, defined using standard consensus criteria: new or worsened abdominal pain consistent with acute pancreatitis, elevation of serum amylase or lipase to at least three times the upper limit of normal within 24 hours after ERCP, and hospitalization or prolongation of planned admission attributable to pancreatitis.
The outcome will be compared between participants receiving prophylactic rectal indomethacin and those receiving placebo.
