RESUMO
OBJECTIVE: To explore the relationship between the hepatobiliary pathological changes under B-ultrasound examinations and Clonorchis sinensis infection, so as to provide the evidence for further prevention and control. METHODS: The stool test and ELISA were applied to test the pathogeny and antibody to C. sinensis of the suspicious patients who had the hepatobiliary pathological changes under B-ultrasound examinations in People's Hospital of Wuxuan County from Jan. 2010 to Dec. 2013. RESULTS: Totally 113 suspicious patients of C. sinensis infection were investigated, and the positive rates of egg and serum antibody were 64.60% (73 cases) and 66.37% (75 cases) respectively. The positive rates of the male and those aged ≥ 50 years were significantly higher than those of the female and the cases younger than 50 years respectively (χ² = 3.554, 6.267, both P < 0.05). In the C. sinensis infected patients, the degree of pathological changes of hepatobiliary was positively correlated with the infectiosity of C. sinensis (χ² = 64.952, P < 0.01). CONCLUSION: The hepatobiliary pathological changes under B-ultrasound examinations may be resulted from the infection of C. sinensis, and the patients with the changes should be further investigated for the pathogen and antibody to C. sinensis.
