Role of EUS in High Risk of Choledocholithiasis

"Endoscopic ultrasound (EUS) is performed with radial scanning echo endoscope (Olympus GF UE260) by four endosonographers.~EUS examination is performed first, and if there is choledocholith, ERCP is performed."

"Endoscopic retrograde cholangiopancreatography (ERCP) is performed with duodenoscope (Olympus JF-260V or TJF-260V) by four endoscopists.~* In the EUS-ERCP group, ERCP is used to remove bile duct stones diagnosed via EUS. Therefore, only ERCP is performed in patients with choledocholithiasis in EUS.~* In the ERCP group, diagnosis and treatment of bile duct stones are performed with ERCP."
