目的探讨超声对华支睾吸虫感染导致的胆道梗阻的诊断价值。方法选取2014年10月至2015年10月华支睾吸虫感染患者54例,回顾性分析其超声影像学表现,并与胆道疾病性胆道梗阻超声影像学表现相鉴别。结果超声影像学表现为胆管分支扩张,肝内胆管壁厚度升高回声增强,似实质性,胆道边缘明显;部分患者胆道内有类似絮状物,回声增强。结论华支睾吸虫感染性胆道梗阻与胆道疾病性胆道梗阻有超声影像学表现差异,超声可作为初步筛查华支睾吸虫感染的有效方法。 Objective To investigate the diagnostic value of ultrasound on biliary obstruction caused by Clonorchis sinensis infection. Methods Fifty-four patients with Clonorchis sinensis infection from October 2014 to October 2015 were retrospectively analyzed, and their imaging features were compared with ultrasound imaging findings of biliary tract obstruction. Results Ultrasound imaging showed dilatation of bile duct branches, increased intrahepatic bile duct wall thickness increased echogenicity, it seems substantive, biliary margin obvious; some patients have similar biliary flocculus, echo enhancement. Conclusion Ultrasound can be used as an effective method for the preliminary screening of Clonorchis sinensis infection in biliary tract infection and biliary obstruction.
