应用肝脏超声波检查方法普查血防巩固地区无自觉症状“健康者”2,789人,结果超声肝脾大者2,024人,超声与体检符合率72.6%;有症状者100人,超声与直肠镜检符合率99.0%。无症状者出现齿状波占多数(48.8%),直肠镜检阳性170人中齿状波占77.0%,阴性718人中齿状波占49.0%。认为在血防巩固地区,对无血吸虫病史者,本法可作为普查过筛工具,可确定肝脾大小,对出现齿状波的“阴性”对象应再做直肠镜检。 The results of ultrasonography were 2,024 with ultrasound and liver biopsy. The coincidence rate of ultrasound and physical examination was 72.6%. The coincidence rate of ultrasound and rectal examination was 99.0 %. In asymptomatic patients, the majority of odontoid waves (48.8%), dentition-like waves in rectal examination positive 170 cases accounted for 77.0%, and negative 718 persons accounted for 49.0%. That in the blood defensive areas, the history of non-schistosomiasis, the law can be used as screening screening tools to determine the size of the liver and spleen, the occurrence of dentate waves “negative” object should do rectal microscopy.
