Papillary Morphology, Periampullary Diverticulum, and Comorbidity Burden in Relation to Cannulation Outcomes and Procedural Difficulty in ERCP

Background

Although it has been suggested that papillary morphology and periampullary diverticulum (PAD) may affect the outcomes of endoscopic retrograde cholangiopancreatography (ERCP), the independent effects of these factors have not been clearly established. In this study, we aimed to evaluate the association of papillary morphology and PAD with ERCP success, procedural difficulty, and post-ERCP complications.
