Key inclusion criteria

Patients underwent ERCP at our hospital between April 2021 and September 2023 with naive papillae of Vater are enrolled in this study.

Key exclusion criteria

Exclusion criteria include patients who underwent the procedure for the second or subsequent times, previous endoscopic sphincterotomy, use of a forward-viewing endoscope or balloon-assisted enteroscopy was used, and discontinuation of treatment for anatomic reasons such as intestinal stenosis.

Patients underwent ERCP at our hospital between April 2021 and September 2023 with naive papillae of Vater are enrolled in this study. Electronic medical records are used to extract data regarding patient age, sex, body mass index, and endoscopic procedures. Patient data related to the ERCP procedure are recorded, including cannulation success or failure, precut sphincterotomy, final cannulation method (conventional contrast cannulation or salvage techniques), pancreatic stenting, trainee operator, reason for ERCP implementation (benign or malignant), and adverse events. Major duodenal papilla morphology is evaluated using endoscopic recordings and images.
The primary outcome of this study is the rate of deep bile duct cannulation difficulty using pattern recognition. We analyze the success rate of deep cannulation using the conventional contrast method and compared it to that of salvage techniques for several recognition patterns. Factors that may increase the risk of requiring salvage techniques are analyzed using multiple regression analysis and scored based on these results. The secondary outcomes include precut sphincterotomies and adverse event rates.
