Post-ERCP hemorrhage in patients with choledocholithiasis: risk factors and prevention / 中华消化内镜杂志

ABSTRACT

Objective To investigate the risk factors and prevention of the ERCP-related upper gastrointestinal bleeding in patients with choledocholithiasis.Methods The clinical data of 678 patients who received ERCP in Yijishan Hospital of Wannan Medical College between January 2014 and December 2014 were reviewed.Univariate and multivariate analyses were performed to define the independent risk factor(s) for delayed hemorrhage following ERCP.Results A total of 383 patients,in whom 157 were males and 226 were females,the age ranged from 19 to 88 years,were recruited to the study.ERCP-related upper gastrointestinal bleeding occurred in 41 patients(10.7％),intraoperative bleeding occurred in 27(7.0％) and postoperative hemorrhage in 14 (3.7％).Twenty-eight cases were mild bleeding,9 moderate (4 caused by laceration of the cardiac mucosa) and 4 were severe bleeding.All patients recovered and were discharged,and no death occurred.No single case required surgical conversion.Univariate analysis revealed that cholangitis,medical history of aspirin/clopidogrel,giant diverticulum and the major papilla inside the diverticulum were risk factors for delayed hemorrhage following ERCP (P ＜ 0.05).Multivariate analysis indicated that independent risk factors were associated with cholangitis (OR =4.125,95％ CI1.306-13.031,P ＜ 0.05),medical history of aspirin/clopidogrel (OR =10.220,95％ CI2.997-34.853,P ＜ 0.01) and major papilla occurred inside the diverticulum(OR =14.064,95％ CI1.888-104.762,P ＜ 0.05).Conclusion Cholangitis,medical history of aspirin/clopidogrel and major papilla at the diverticulum may increase the risks for upper gastrointestinal bleeding in ERCP in patients with choledocholithiasis.However,the hemorrhage should be actively managed,especially in endoscopy,once the bleeding occurs.
