磁共振胰胆管成像在肝外胆结石中的诊断价值

Diagnostic value of MR cholangiopancreatography in extrahepatic cholelithiasis

目的分析腹部CT诊断方法和磁共振胰胆管成像诊断方法在肝外胆结石患者临床诊断中的应用价值。方法选取2017年4月-2019年9月高唐县人民医院诊断的50例肝外胆结石患者作为观察对象,所有患者采取手术病理诊断或是经内镜逆行性胰胆管造影术诊断最终确诊都存在肝外胆结石。依据随机双盲法将患者分为研究组和对照组各25例,研究组选用磁共振胰胆管成像诊断方法,对照组选用腹部CT诊断方法,比较两组肝外胆结石的总确诊率、<9 mm结石的总检出率、患者总满意率。结果研究组肝外胆结石的总确诊率为88.00%,高于对照组的60.00%;研究组<9 mm结石的总检出率为80.95%,高于对照组的50.00%;研究组患者总满意率为96.00%,高于对照组的76.00%,差异均有统计学意义(P<0.05)。结论在肝外胆结石患者临床诊断中,运用磁共振胰胆管成像诊断方法的诊断效果优于腹部CT诊断方法,值得临床推广应用。

Objective To analyze the application value of abdominal CT diagnosis and MR cholangiopancreatography in the clinical diagnosis of extrahepatic cholelithiasis. Methods From April 2017 to September 2019,50 patients with extrahepatic cholelithiasis diagnosed by Gaotang County People’s Hospital were selected as the observation objects. All patients were diagnosed with extrahepatic cholelithiasis by surgical pathology or by endoscopic retrograde cholangiopancreatography. According to the randomized double-blind method,the patients were randomly divided into study group and control group with 25 cases in each group. The diagnostic method of MR cholangiopancreatography was used in the study group,and the diagnostic method of abdominal CT was used in the control group. The total diagnosis rate of extrahepatic cholelithiasis,the total detection rate of gallstones less than 9 mm,and the total satisfaction rate of patients were comparted between the two group. Results The total diagnosis rate of extrahepatic cholelithiasis in the study group was 88.00%,which was higher than 60.00% of the control group;the total detection rate of gallstones less than 9 mm in the study group was 80.95%,which was higher than 50.00%in the control group;the total satisfaction rate of the study group was 96.00%,which was higher than 76.00% of the control group,and the differences above all were statistically significant(P <0.05).Conclusion In the clinical diagnosis of patients with extrahepatic cholelithiasis,the diagnostic effect of MR cholangiopancreatography was better than that of abdominal CT,which was worthy of clinical promotion and application.
