目的 探讨ERCP联合MRI在诊断胰 胆管疾病中的临床价值。方法 选取我院 2015年1月-2016年1月期间收治的90例胰 胆管疾病患者，均行ERCP与MRI检查，所 有患者经过手术、活检及病理证实为胆总 管结石45例、胰腺癌20例、胆管癌并梗阻 12例、慢性胰腺炎8例、胆道蛔虫感染5 例，临床表现为黄疸、反复上腹部疼痛、 恶心呕吐。结果 ERCP对胆总管结石、胰 腺癌、胆管癌并梗阻、慢性胰腺炎、胆 道蛔虫感染诊断准确率依次为95.56%、 100%、75.00%、87.50%、100%，MRI诊断 准确率依次为86.67%、85.00%、75.00%、 87.50%、80.00%，ERCP对胰胆管疾病的诊 断准确率略高于MRI诊断准确率，但比较 无统计学意义(P＞0.05)；ERCP与MRI胰胆 管疾病的影像特征表现不同。结论 ERCP 与MRI对诊断诊断胰胆管疾病有较高的一 致性，二者联合应用可大大提高诊断疾病 准确率，并可根据影像特点互补诊断。

Objective To explore the clinical value of ERCP combined with MRI in the diagnosis of pancreaticobiliary diseases. Methods Ninety patients with pancreaticobiliary diseases who were admitted into our hospital between January 2015 and January 2016 were examined by ERCP and MRI examination. All patients were confirmed by surgery, biopsy and pathology. There were 45 cases with choledocholithiasis, 20 cases with pancreatic cancer, 12 cases with bile duct carcinoma complicated with obstruction, 8 cases with chronic pancreatitis and 5 cases with biliary tract roundworm infection. The clinical manifestations included jaundice, repeated upper abdominal pain, nausea and vomiting. Results The accuracy rates of ERCP in the diagnosis of choledocholithiasis, pancreatic cancer, bile duct carcinoma with obstruction, chronic pancreatitis and biliary tract roundworm infection were 95.56%, 100%, 75.00%, 87.50% and 100% while those of MRI were 86.67%, 85.00%, 75.00%, 87.50% and 80.00%. The accuracy rate of ERCP in the diagnosis of pancreaticobiliary diseases was slightly higher than that of MRI but there was no statistical difference (P>0.05). The ERCP and MRI features of pancreaticobiliary diseases were different. Conclusion ERCP and MRI have high consistency in the diagnosis of pancreaticobiliary diseases. The combined application of the two can greatly improve the accuracy of diagnosis and both of the two can be used as complementary diagnosis according to the imaging features.
