磁共振胰胆管成像征象分析对良恶性胆道梗阻的诊断价值

Diagnostic value of magnetic resonance cholangiopancreatography in the diagnosis of benign and malignant biliary tract obstructive disease

目的分析磁共振胰胆管成像征象分析对良恶性胆道梗阻的诊断价值。方法对我院收治的124例临床怀疑有胆道梗阻疾病患者的MRCP影像及全部临床资料进行回顾性分析,所有患者均详细询问病史、查体及行相关实验室检查后再行MRCP检查,结果最终由手术病理或随访证实。分析所有患者的MRCP影像学特点。结果"软藤征""双管征""三管征"及"四管征"等在恶性胆道梗阻患者中的发生率显著高于良性胆道梗阻患者(P<0.05);而"枯树征"在良性胆道梗阻患者中的发生率显著高于恶性胆道梗阻患者(P<0.05)。结论 MRCP可准确反应胆道扩张的特征,其对良恶性胆道梗阻显示率高,诊断具有一定的特异性征象。

Objective To analyze the diagnostic value of magnetic resonance cholangiopancreatography（MRCP） in the diagnosis of benign and malignant biliary tract obstructive disease. Methods The MRCP imaging and clinical data of 124 patients with clinical suspicion of biliary obstructive diseases admitted in our hospital were retrospectively analyzed. All the patients received MRCP after asking detailed medical history, taking physical examination and related laboratory examinations, the results were confirmed by surgery pathology or follow-up. The MRCP imaging features of all the patients were analyzed. Results The incidences of ＂soft rattan sign＂, ＂double segment sign＂, ＂three-segment sign＂ and ＂four-segment sign＂ in the malignant biliary tract obstructive disease patients were higher than those in the benign biliary tract obstructive disease patients（P〈0.05）. The incidence of ＂dead branches syndrome＂ in the benign biliary tract obstructive disease patients was higher than that in the malignant biliary tract obstructive disease patients（P〈0.05）. Conclusion MRCP can accurately reflect the characteristics of biliary tract dilatation and show a high rate of benign and malignant biliary obstruction, which has some specific signs.
