The main objective of the study is: the identification of independent factors associated with an increased risk of post-ERCP complications. Other objectives are: the development of a predictive model of events post-ERCP adverse events and its validation; geographic validation of a predictive model already published in the literature using data collected during the study and the evaluation of the rate of post-ERCP AEs in the centers involved in the study.
