探讨各种超声征象在Caroli病诊断中的应用价值
To Investigate the Application Value of Ultrasonic Signs in Diagnosis of Caroli Disease

目的：探讨各项超声征象在诊断Caroli病中的应用价值。资料与方法：回顾性分析2003年1月~2021年12月于我院就诊的15例Caroli病的超声图像及临床资料，所有病例均经肝穿刺活检组织学或增强CT证实。观察并记录声像图是否存在肝内囊性病变，囊性病变内是否出现“中心圆点征”、“桥征”、“串珠征”、“囊尾征”以及高频线阵探头模式下肝内囊性病变与肝内胆管壁是否存在连续性。结果：①14例超声图像见肝内囊性病变；②单独以腹部低频探头观察到“中心圆点征”、“桥征”、“串珠征”、“囊尾征”作为诊断征象，诊断CD分别为5例、5例、4例、6例，诊断符合率分别为33.3%、33.3%、26.7%、46.7%；单独以高频线阵探头观察到肝内囊性病变与肝内胆管相连续作为诊断征象，诊断CD为11例，诊断符合率为73.3%，与上述征象诊断符合率比较，差异均有统计学意义(P均<0.05)。结论：高频线阵探头观察到肝内囊性病变与肝内胆管相连续是Caroli病最重要的超声诊断征象，超声诊断符合率为73.3%。
Purpose: To investigate the application value of various ultrasonic signs in diagnosis of Caroli dis-ease. Materials and Methods: Ultrasound images and clinical data of 15 patients with Caroli disease admitted to our hospital from January 2003 to December 2021 were retrospectively analyzed. All cases were confirmed by liver biopsy histology or enhanced CT. The ultrasonography was observed and recorded whether there were intrahepatic cystic lesions, whether there were “central dot sign”, “bridge sign”, “beaded sign” and “caudal sign” in the cystic lesions, and whether there was continui-ty between intrahepatic cystic lesions and intrahepatic bile duct wall under high- frequency linear array probe mode. Results: ① Hepatic cystic lesions were observed in 14 cases. ② “Central dot sign”, “bridge sign”, “beaded sign”, and “caudal sign” were observed as diagnostic signs by low-frequency abdominal probes alone, CD was diagnosed in 5, 5, 4 and 6 cases, respectively, and the coincidence rates were 33.3%, 33.3%, 26.7% and 46.7%, respectively. Continuous intrahepatic cystic lesions and intrahepatic bile duct were observed separately by high-frequency linear array probe as diag-nostic signs, CD was diagnosed in 11 cases, and the diagnostic coincidence rate was 73.3%. The dif-ferences were statistically significant compared with the diagnosis coincidence rate of the above signs (P < 0.05). Conclusion: Continuous intrahepatic cystic lesion and intrahepatic bile duct ob-served by high-frequency linear array probe is the most important ultrasonic diagnosis sign of CD, and the coincidence rate of ultrasonic diagnosis is 73.3%.
