Abstract

Background and Aims: Cannulation of the major papilla can be problematic, and selective biliary cannulation may fail in up to 18% of cases. Various techniques, such as double-guidewire technique (DGWT), wire-guided cannulation over a pancreatic stent (WGC-PS), the precut endoscopic sphincterotomy (needle-knife precutting technique (NKP), and transpancreatic septostomy have been used to improve the success rate of biliary cannulation. We conducted a prospective, randomized study in order to compare the biliary cannulation success rates of DGWT and WGC-PS techniques in patients with inadvertent passage of guidewire to the pancreatic duct.
