Evaluation of selective cholangiography under the guidance of endoscopic ultrasonograpy / 中华消化内镜杂志

ABSTRACT

Objective To determine the diagnostic value of endoscopic ultrasound-guided cholangiography(EUSGC)with fine needle puncture .Methods Twenty-six patients with obstructive jaundice failed i n previous endoscopic retrograde cholangiopancreatography(ERCP) and magnetic res onance cholangiopancrcatography(MRCP) or have metallic foreign materials in some where of body. By a linear scanning echoendoscopy in conjunction with a 22-gau ge aspiration needle, transduodenal selective cholangiography was attempted.Results Cholangiography was successfully performed in all patie nts (EUSGC success 100% vs. ERCP 0%). No complications occurred in the patients. In 19 patients, abnormalities were found from EUSGC. Choledocholithiasis have b een confirmed by sphincterotomy(n=5),common bile duct strictures were confirmed by surgical operation(n=11).Three other patients have delayed excretion of co ntract medium.Conclusion EUSGC allows a safe and accurate alternative method for obtaining cholangiography in those patients when ERCP or MRCP failed.
