    Aims:

    Endoscopic access to common bile duct remains difficult in 10% of cases undergoing endoscopic retrograde cholangiopancreaticography (ERCP). Different guidewires with various tip shapes have been used for increasing biliary cannulation rate. In current study, we evaluated the effectiveness of the Visiglide2(®) guidewire for biliary cannulation.

    Methods:

    We conducted a prospective, randomized controlled study involving patients with a naïve papilla who required biliary cannulation. We randomly allocated the patients to the Visiglide2 guidewire (Group V) or conventional guidewire (Group C). The primary success rate of selective biliary cannulation was defined when the cannulation was achieved within 10 min and incidental pancreatic duct cannulation was not occurred over 3 times. The primary success biliary cannulation rate, the time for cannulation, the number of papillary attempts, the number of pancreatic duct cannulation, the time for total procedure and final success rate were recorded during endoscopic procedure. The complications related with ERCP were evaluated for 2 days after procedure.

    Results:

    One hundred patients were enrolled and assigned to group V (n = 50) and C (n = 50) in current study. The primary success biliary cannulation rate was 96% (48/50) for group V and 86% (43/50) for group C (P = 0.08). The final success rate for biliary cannulation was 100% in both groups. The mean times for biliary cannulation were 174.9 s for group V and 363.5 s for group C (P = 0.04). The number of papillary attempt for cannulation (group V, 1.84; group C, 3.44; P < 0.01) and the frequency of incidental pancreatic duct cannulation (0.48; 0.8; P = 0.15) was significant lower in group V than those of group C. The incidence of total adverse event related with procedure was not significantly difference between groups.

    Conclusions:

    The biliary cannulation rate was significantly improved using by Visiglide2 guidewire compared to conventional guidewire
