Abstract
Background/Aims:
Few studies have addressed the relationship between the occurrence of adverse events (AEs) associated with endoscopic retrograde cholangiopancreatography (ERCP) and hospital case volume or the experience of the endoscopist, but the results have been inconsistent. The aim of our study was to investigate the impact of hospital case volume and the experience of the endoscopist on the AEs associated with ERCP and to analyze patient- and procedure-related risk factors for post-ERCP AEs.

Methods:
From January 2015 to December 2015, we prospectively enrolled patients with naïve papilla who underwent ERCP at six centers. Patient- and procedure-related variables were recorded on data collection sheets at the time of and after ERCP.

Results:
A total of 1,191 patients (median age, 71 years) were consecutively enrolled; 846 (71.0%) were from four high-volume centers, and 345 (29.0%) were from two low-volume centers. The overall success rate of deep bile duct cannulation was 96.6%. Overall, 244 patients (20.5%) experienced post-ERCP AEs, including pancreatitis (9.0%), bleeding (11.8%), perforation (0.4%), cholangitis (1.2%), and others (0.9%). While post-ERCP pancreatitis (PEP) was more common when the procedure was performed by less experienced endoscopists, bleeding was more common when the procedure was performed in high-volume centers and by less experienced endoscopists. Multivariate analysis showed that a less experience in ERCP was significantly associated with PEP (odds ratio [OR], 1.630; 95% confidence interval [CI], 1.050 to 2.531; p=0.030) and post- ERCP bleeding (OR, 1.439; 95% CI, 1.003 to 2.062; p=0.048).

Conclusions:
Our study demonstrated that overall AEs following ERCP were associated with the experience of the endoscopist. To minimize post-ERCP AEs, rigorous training with a sufficient case volume is required, and treatment strategies should be modified according to the endoscopist’s expertise
