Rev. esp. enferm. dig. [online]. 2017, vol.109, n.3, pp.202-210. ISSN 1130-0108.  https://dx.doi.org/10.17235/reed.2017.4358/2016.

Aims: To analyze the risk factors for hemorrhage during endoscopic retrograde cholangiopancreatography and the impact of antithrombotic drugs. Material and methods: Data sources: papers indexed in PubMed have been reviewed, as well as those found during the analysis of the bibliography of meta-analysis and reviews. Selection criteria: the references have been firstly evaluated by review of the abstract. After selecting the most significant articles (mainly randomized trials and well-designed case series) these have been deeply analyzed. Evaluation of the studies and synthesis: criteria by the Oxford Centre for Evidence-Based Medicine have been used for the analysis of the references and elaboration of evidence levels. Results: Seven hundred and sixty-five references were found, 753 in PubMed and the Cochrane Library. Twelve studies were selected during the analysis of other published articles (systematic reviews, meta-analysis and clinical practice guidelines). After analyzing the title or the abstract, 655 studies were excluded. Finally, 83 high quality trials or descriptive studies have been included in the analysis. Conclusions: Seven conclusions regarding the risk factors for bleeding and the impact of antithrombotic drugs have been defined.

Keywords : Antithrombotic drugs; Clopidogrel; Aspirin; Anticoagulants; Sphincterotomy; Bleeding.
