ABSTRACT
Objective To evaluate the effectiveness and safety of the double-guidewire technique (DGT) using a new double-guidewire-supported sphincterotome (MagicTome) for patients who required endoscopic retrograde cholangiopancreatography (ERCP) for biliary cannulation. Methods This prospective multicenter randomized feasibility trial involved patients with difficult biliary cannulation at any of the three study sites from June 2017 to October 2018. Patients were assigned to the DGT with MagicTome (MDGT) initially performed group and the conventional DGT (CDGT) initially performed group. The success rates of biliary cannulation by MDGT and CDGT and the ERCP-related complications were evaluated. Results Twenty-eight patients were included in this study. No significant difference was observed in the success rates of first attempts and crossover attempts between the groups (p=0.69 and p=1.00). Furthermore, no significant difference was observed in the success rate of biliary cannulation between MDGT and CDGT (62.5% and 75.0%, respectively; p=0.48). CDGT was successful in two of four patients with malignant biliary obstruction. MDGT was successful in all four patients with malignant biliary obstruction, including the two for whom CDGT was unsuccessful. Post-ERCP pancreatitis occurred in only one MDGT case. Conclusion MDGT is safe for biliary cannulation and can be used in cases where biliary cannulation by CDGT is difficult.
