Pre-cut papillotomy significantly increases bleeding risk during ERCP, unlike conventional papillotomy. Low-molecular-weight heparin use also elevates bleeding risk, but abnormal coagulation tests do not predict it.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Hepatology

Background:

  • Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure.
  • Bleeding is a known complication of ERCP, particularly after papillotomy.
  • Identifying risk factors for ERCP-associated bleeding is crucial for patient safety.

Purpose of the Study:

  • To identify risk factors for bleeding associated with ERCP.
  • To evaluate the impact of different papillotomy techniques on bleeding rates.
  • To assess the influence of antithrombotic medications and coagulation parameters on ERCP-related bleeding.

Main Methods:

  • Retrospective analysis of 598 ERCP procedures in 399 patients.
  • Evaluation of bleeding incidence based on procedure type (pre-cut vs. conventional papillotomy) and medication use.

  • Analysis of clotting parameters and hemoglobin levels as potential predictors of bleeding.

    • Main Results:

    • Overall ERCP-associated bleeding rate was 3.0%.
    • Pre-cut papillotomy significantly increased bleeding risk (15.2%) compared to conventional papillotomy (1.9%).
    • Low-molecular-weight heparin use was associated with a significantly higher bleeding incidence (10.3%), while platelet aggregation inhibitors did not show a significant increase.

    Conclusions:

    • Pre-cut papillotomy is a significant risk factor for ERCP-associated bleeding.
    • Low-molecular-weight heparin use during ERCP increases bleeding risk.
    • Abnormal coagulation tests do not reliably predict ERCP-associated bleeding.
