From: Wire-guided cannulation over a pancreatic stent versus double guidewire technique in patients with difficult biliary cannulation

  WGC-PS (n = 90) DGT (n = 87) P value
Initial success rate, n (%) 60 (66.7) 61 (70.1) 0.632
Success rate without NKF, n (%) 60 (66.7) 75 (86.2)* 0.003
Overall success rate, n (%) 87 (96.6) 86 (98.9) 1.000
Pancreatitis, total, n (%) 3 (3.3) 9 (10.3) 0.077
Mild, n 3 7  
Moderate, n 0 2  
Bleeding, n 0 0  
Perforation, n 0 0  
  1. WGC-PS wire-guided cannulation over a pancreatic stent, DGT double guidewire technique, NKF needle-knife fistulotomy
  2. *In 26 patients who had failed DGT, WGC-PS was sequentially performed, and cannulation was successful in 14 of these patients
