摘要
目的:探讨B超、MSCT和MRCP在胆道梗阻性疾病中的诊断价值。方法:采用前瞻性的对照研究方法,病例入组标准为:①每例患者均行3种检查方法;②每例均经病理或综合检查证实为胆道梗阻性疾病。于2010年10月至2011年10月间共获得96例病例,包括胆管结石24例,胆管炎性狭窄11例,慢性胰腺炎15例,胆总管囊肿3例,肝门胆管癌9例,胆总管癌6例,胰头癌13例,壶腹癌5例,胆囊癌10例。分析其影像学表现,对3种检查方法进行比较。结果:B超、MSCT和MRCP对良性病变的定性准确率分别为79.2%、96.2%、92.5%;对恶性病变的定性准确率分别为76.7%、97.7%、93.0%;总的定性准确率分别为78.1%、96.9%、92.7%;总的定位准确率分别为86.5%、97.9%、99.0%。结论:3种检查方法对胆道梗阻疾病的准确率不同,且各有优缺点,建议临床采用综合的检查方法。
Purpose： To study the diagnostic value of B ultrasound, 64-slice spiral CT and MRCP in biliary obstructive diseases. Methods： The prospective case-control study was performed and the criteria for every case into the group were as follows： QEvery patient underwent these three methods~ @Every case was confirmed by pathology or a comprehensive examination result of the biliary obstructive disease. From October 2010 to October 2011, a total of 96 cases were obtained, including 24 cases of bile duct stones, 11 cases of cholangitis stenosis, 15 cases of chronic pancreatitis, 3 cases of congenital choledochal cyst, 9 cases of hilar bile duct carcinoma, 6 cases of common bile duct carcinoma, 13 cases of pancreas head carcinoma, 5 cases of ampulla carcinoma, and 10 cases of gallbladder carcinoma. The images of the B ultrasound, CT and MRCP were analyzed, and the results of them were compared. Results： The accuracies of B ultrasound, MSCT and MRCP in evaluating the nature of benign diseases were 79.2%, 96.2%, 92.5%, respectively. The accuracies in evaluating the nature of malignant diseases were 76.7%, 97.7%, 93.0%, respectively. The total accuracies in evaluating the nature of biliary diseases were 78.1%, 96.9%, 92.7%, respectively. The total accuracies in evaluating the site of biliary diseases were 86.5%, 97.9%, 99.0%, respectively. Conclu- sion： The accuracy of three methods for diagnosis of obstructive diseases were different and every methods has advantages and disadvantages, so comprehensive imaging methods were recommended in clinical applications.
