Background and Aim: Selective bile duct cannulation is a prerequisite for performing therapeutic endoscopic biliary intervention. This study aimed to evaluate if using a soft‐tipped guidewire to cannulate the bile duct would increase the success rate of needle‐knife fistulotomy for difficult bile duct access. Methods: We reviewed sixty 60 patients with difficult bile duct access who underwent conventional cannulation with radiocontrast dye (29) or guidewire cannulation (31) after needle‐knife fistulotomy. Results: There were no significant differences in the demographic data between the two groups. The initial success rate of selective bile duct cannulation was significantly higher in the guidewire cannulation group compared with the conventional cannulation group: 100% versus 79.3%, P = 0.009. The success rate of selective biliary cannulation in the patients with non‐dilated common bile duct (< 8 mm) was significantly higher in the guidewire cannulation group compared with the conventional cannulation group: 100% versus 68.4%, P = 0.003. The incidence of post‐endoscopic retrograde cholangiopancreatography pancreatitis was not significantly different between the two groups. No serious complications occurred in either group. Conclusions: In this retrospective and small case series, guidewire cannulation after needle‐knife fistulotomy increased the success rate of selective bile duct cannulation in patients with difficult bile duct access.
