Objective: Wire-guided cannulation (WGC) reportedly increases the successful biliary cannulation rate and reduces the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis. Currently, various types of guidewires are available. However, the effect of the length of flexible-tip guidewires on the success rate of biliary cannulation under WGC and the rate of adverse events, especially post-endoscopic retrograde cholangiopancreatography pancreatitis, is unclear. The aim of this stu
