Intrahepatic bile duct (IHBD) stones are usually removed under endoscopic retrograde cholangiopancreatography (ERCP) [1] [2] [3]. However, ERCP can be challenging when patients have a complicated surgical anatomy. Various intervention techniques under endoscopic ultrasound (EUS) guidance, such as antegrade stone removal, have been applied [4], but right IHBD stone removal can be difficult owing to device limitations.
