BACKGROUND:Wire-guided cannulation has become a common biliary cannulation technique worldwide. Different guidewires with various tip shapes and materials have been reportedly used for wire-guided cannulation. However, there are apparently no studies reporting changes in the biliary cannulation rate according to the type of guidewire used. AIMS: We evaluated the effectiveness of the J-tip guidewire for biliary cannulation. METHODS: We conducted a prospective, multicenter, controlled study involving patients with a native papilla who required biliary cannulation. We allocated the patients to the J-tip guidewire or angled-tip guidewire groups (groups J and A, respectively). If biliary cannulation was not achieved within 10 min, the GW was changed and cannulation was continued. RESULTS: Groups J and A consisted of 66 and 65 enrolled patients, respectively. The biliary cannulation rate with a single guidewire for the first 10 min was 84.8 % (56/66) for group J and 80.0 % (52/65) for group A. The final success rate for biliary cannulation was 100 % in both groups. The mean times necessary for biliary cannulation were 285.8 and 267.6 s in group J and group A, respectively. The incidence rates of complications (i.e., all mild pancreatitis) were 3.0 % (2/66) and 6.2 % (4/65) in group J and group A, respectively. The mean amylase concentrations were 168.0 and 297.7 IU/L in group J and group A, respectively. There were no significant differences in any results between both groups. CONCLUSION: The biliary cannulation rate of the J-tip guidewire was not significantly different from those of standard guidewires.
