[Discussion on relationship between hepatobiliary pathological changes under B-ultrasound and Clonorchis sinensis...

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.

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.

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).

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.
