¹Cannulation using a sphincterotome with or without a guidewire;

²Cannulation with a needle-knife after failure with a sphincterotome;

³Two minor papillotomy procedures using the needle-knife were performed along a guidewire after successful cannulation with the sphincterotome;

⁴Times were recorded in 17 procedures using a sphincterotome and 5 procedures using a needle-knife. ERCP: Endoscopic retrograde cholangiopancreatography; ENPD: Endoscopic naso-pancreatic drainage.
