Prevalence and Predictive Factors of Difficult Biliary Cannulation

The main purpose of the study is to evaluate the prevalence of difficult biliary cannulation using endoscopic retrograde cholangiopancreatography (ERCP) according to the criteria defined by the European Society of Gastrointestinal Endoscopy (ESGE) and the American Society for Gastrointestinal Endoscopy (ASGE), as well as the predictive factors for this event in a prospective, multicenter study. Consecutive patients undergoing ERCP will be included in the study We will also assess: Evaluate the failure of biliary cannulation in our setting. Evaluate predictive factors for difficult cannulation and cannulation failure using ESGE criteria. Design an "a priori" predictive model for difficult cannulation and cannulation failure. Cost study: record of materials used.
