按照世界卫生组织1990年开罗会议制定的”超声诊断在血吸虫病应用中的试行标准化方法”，在日本血吸虫所致肝脏病理损害超声图上可显示明确特征性的基础上，作者于1992年在血吸虫病重疫区的两个自然村，整群抽样1004例村民进行腹部B超检查。结果显示肝实质有不同程度改变者639人（63．6％），其中肝实质改变为I级者454人（45．2％）、Ⅱ级131人（13．0％）、Ⅲ级54人（5．4％）。肝实质超声图显示异常者中粪检、免疫学检查、直检阳性者与各项检测阴性者进行比较，两组超声异常率分别为74．1％及9．8％（P＜0．01），而非流行村200例配对对照组未发现1例超声异常。另通过对成人和儿童肝、脾、门静脉内径的超声测量结果表明，判断异常的标准值尚有待进一步探讨。本研究再次证实了B超在现场应用中，对人群血吸虫病患病率的评估和防治效果的判断具有实用价值，可作为该病流行病学调查的一种较好的方法。
According to the World Health Organization’s 1990 Cairo Conference “diagnostic ultrasound in the application of schistosomiasis trial standardization method” in Schistosoma japonicum caused by pathological lesions on liver ultrasound can be clearly characterized on the basis of the author in 1992 in schistosomiasis Two natural villages with severe outbreaks and 1004 villagers in a cluster sample were examined by abdominal ultrasonography. The results showed that there were 639 (63.6%) patients with varying degrees of liver parenchyma, including 454 (45.2%) of grade I, 131 (11.0%) of grade II and 54 (5.4%). Liver abnormalities were abnormal in fecal examination, immunological examination, direct test positive and negative test were compared, the two groups were 74.1% and 9.8% respectively (P <0.01 ), While 200 non-endemic villages matched control group found no abnormal ultrasound. Another by adult and children liver, spleen, portal vein diameter measurement results show that the standard value to determine the anomaly remains to be further explored. This study confirms once again that B-ultrasound has practical value in assessing the prevalence of schistosomiasis and preventing and controlling the disease in the field, so it can be used as a good method for epidemiological investigation of this disease.
