Advanced techniques yield 100% final success in difficult biliary cannulation, crucial for ensuring effective ERCP outcomes.

• Initial cannulation success: 72% (double-guidewire), 68% (trans-pancreatic sphincterotomy), 68% (precut fistulotomy).
• Precut technique used less contrast dye (p<0.005).

Consider individualizing the technique based on patient anatomy and operator skill for optimal outcomes.

• Post-ERCP pancreatitis rates were 10% (dgt), 22% (tps), and 24% (precut) with no significant differences in other adverse events.
