Guidewire Management in ERCP

Intra-procedural guidewire management is a parameter whose impact remains incompletely understood in terms of its association with post- endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). Inadvertent guidewire cannulation of the pancreatic duct (PD) when attempting common bile duct (CBD) cannulation is recognized as a risk factor for PEP. However, to date, no studies have assessed whether a single PD wire cannulation is associated with a higher PEP risk compared to no PD cannulations. Similarly, the relationship between each additional PD cannulation and the incremental magnitude of PEP risk remains unclear. In this study, the investigators will aim to assess whether a single inadvertent PD cannulation (versus no PD cannulation) is associated with an increased risk of PEP (the primary outcome).
