磁共振胰胆管成像在胆囊结石并发胆总管扩张患者中的应用价值

Application value of MRCP examination in cholecystolithiasis patients with bile duct dialatation

目的探讨磁共振胰胆管成像(magnetic resonance cholangiopancreatography,MRCP)在胆囊结石并发胆总管扩张患者中的应用价值。方法对200例超声诊断为胆囊结石并发胆总管扩张的患者实施MRCP检查,并根据MRCP诊断结果分为胆总管结石组和单纯胆囊结石组,对比分析2组患者的临床资料。结果 200例患者中胆总管结石组122例,单纯胆囊结石组78例,最终内镜逆行性胰胆管造影(endoscopic retrograde cholangiopancreatography,ERCP)证实胆总管结石119例。胆总管结石组患者胆总管直径、胆总管扩张程度分级、胆红素水平、碱性磷酸酶、γ-谷氨酰转移酶(γ-glutamyltransferase,γ-GT)、胰腺炎病史均高于单纯胆囊结石组,差异有统计学意义(P<0.05)。结论对于超声诊断为胆囊结石伴有胆总管扩张的患者,应积极行MRCP检查,以降低漏诊率。

Objective To explore the application value of magnetic resonance cholangiopancreatography（MRCP）examination in cholecystolithiasis patients with choledochectasia.Methods Prospective analysis was performed in the clinical data of 200 cholecystolithiasis with bile duct dialatation patients by ultrasound.MRCP examination was made for the patients,and,then the patients were divided into choledocholithiasis group and control group according to the MRCP founding.The data of two groups were compared.Results According to the MRCP founding,there were 122 of 200 patients in the choledocholithiasis group and 78 patients in the control group.And finally there were 119 patients with choledocholithiasis according to the endoscopic retrograde cholangiopancreatography（ERCP）therapy.And the data of diameter of bile common duct,classification of common bile duct dilation,bilirubin,alkaline phosphatase,γ-glutamyltransferase（γ-GT）between two groups had statistical differences.Conclusion To the patients diagnosed as cholecystolithiasis with choledochectasia by ultrasound,MRCP examination should actively perform in order to reduce the missed diagnosis rate.
