Evaluating how the appearance of the major duodenal papilla affects post-ERCP pancreatitis risk

Prediction of Post-Endoscopic Retrograde Cholangio-Pancreatography Pancreatitis Based on the Appearance of the Major Duodenal Papilla: a Prospective, Observational, Cohort Study

Observational Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT05800626

This study is trying to see if the shape of a specific part of the intestine affects the risk of developing pancreatitis after a procedure called ERCP, which is used to treat bile duct problems.

What this trial studies

This observational study aims to assess the relationship between the morphological appearance of the major duodenal papilla and the occurrence of post-Endoscopic Retrograde CholangioPancreatography (ERCP) acute pancreatitis. By evaluating the difficulty of biliary cannulation based on papilla types, the study seeks to establish metrics for procedural quality and competence. The findings could help identify challenging cases that should be handled by experienced practitioners to reduce the risk of complications during ERCP procedures.

Who should consider this trial

Good fit: Ideal candidates include patients with a native duodenal papilla who require ERCP for biliary indications and can provide informed consent.

Not a fit: Patients undergoing ERCP for non-biliary disorders or those with previous gastrointestinal surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved patient safety and outcomes by minimizing the risk of post-ERCP acute pancreatitis.

How similar studies have performed: While this approach is observational and may build on existing knowledge, it is not widely tested in this specific context, making it a novel investigation.
