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.
ABSTRACT
Through analyzing and considering on concrete conditions of the clinical engineering, which finds that the function allocation of department is not accurate and summarizes that should based on the technical support work and gain the development opportunity in the initial stage. According to the service theory of "all patients as the center" combines with economic and social benefits to analyze the specific circumstances of provincial and municipal hospitals, the functions location and development idea of clinical engineering department in all levels of hospital are researched respectively so that all work can be carried out smoothly and complete the important mission which hospital endow with the subject.
