Selective bile duct cannulation is the most important step in endoscopic retrograde cholangiopancreatography (ERCP) for treatment of benign and malignant pancreatobiliary diseases, but it may fail in up to 15% of cases. Precut papillotomy is an advanced ERCP cannulation technique recommended by guidelines for rescue of difficult biliary access, but it is not without limitations. Endoscopic ultrasound (EUS)-guided biliary drainage is a novel interventional EUS technique that has been increasingly performed after failed biliary access by advanced ERCP cannulation techniques.
