Table 3 Rescue cannulation techniques

Variables	Dome tip	Tapered tip	P value1
Switching the sphincterotome to either a dome tip or a tapered tip	7	2	0.34
Pancreatic duct guidewire technique	3	3	0.60
Precut sphincterotomy	1	1	0.59
Total	11	6

¹P values were calculated using the t-test for continuous variables and χ² test for categorical variables.
