Objectives

Narrative objectives1

The double-guidewire technique (DGT), in which a second guidewire is used to attempt biliary cannulation while a guidewire is left in the pancreatic duct, is one of the salvage techniques for difficult biliary cannulation during ERCP. Although DGT has been reported to improve biliary cannulation success in difficult cases, it may also increase the risk of post-ERCP pancreatitis (PEP) because of pancreatic guidewire placement and repeated pancreatic manipulation. However, it remains unclear which components of the DGT procedure are associated with the development or severity of PEP. We therefore conducted a multicenter observational study to investigate the risk factors for PEP in patients undergoing DGT.

Assessment

Primary outcomes

Incidence of post-ERCP pancreatitis (PEP) and identification of risk factors for PEP among patients undergoing the double-guidewire technique (DGT)

Key secondary outcomes

Identification of risk factors for moderate-to-severe PEP, as well as factors associated with prolonged biliary cannulation time and unsuccessful biliary cannulation among patients undergoing DGT
