摘要
目的分析人体感染阔节裂头绦虫虫卵、节片及成虫形态特征,并对阔节裂头绦虫病进行鉴别诊断。方法观察虫卵、节片、成虫形态特征,测量所获虫卵并作鉴别诊断;用槟榔南瓜子法驱虫;与既往病例进行病史、驱虫方法和成虫形态等比较。结果驱虫后获得1条具匙状头节,长度约3m阔节裂头绦虫成虫;镜检虫卵近椭圆形,卵壳较厚,有卵盖,另一端有小棘;50个虫卵测量结果的均值,长67.2μm,宽42.6μm;与既往病例比较,发现病例均因食用未煮熟的鱼肉而感染患病。结论阔节裂头绦虫寄生于肠道,多数感染者因无明显症状而被忽视。感染者可引起胆道梗阻、肠穿孔、恶性贫血等严重并发症。近年少见阔节裂头绦虫感染病例,但仍应引起广泛重视。
Objective To analyze morphological characteristics of egg,segment and adult of Diphyllobothrium latuminfection of human body and make differential diagnosis for the disease.Mathods Morphological characteristics of eggs,segments and adults of Diphyllobothrium latum were observed,measured and the differential diagnosis were made.The worms were expelled by areca and pumpkin seeds.Compared with the previous cases in disease history,worms repellent methods and the morphology characteristics of the adult worm.Results After worms repellent,one adult Diphyllobothrium latum was obtained with spoon shaped head and about 3 min length.The results by microscopic examination,the egg was nearly oval,with thick shell and there was egg cover and small spines at the other end of the egg,The mean length was 67.2μm and the width was 42.6μm(n=50 eggs).Compared with the previous cases,it was found that all the cases were infected by eating uncooked fish.Conclusion Diphyllobothrium latum parasitized in intestinal tract,most of the infected cases ignored the disease because there existed no obvious symptoms.The infected cases can result in serious complications,such as biliary obstruction,intestinal perforation,pernicious anemia and so on.Although infrequent cases with Diphyllobothrium latumcan be found in recent years,but the parasitosis prevention should still be paid more attention.
