麝猫后睾吸虫(Opisthorchis viverrini)寄生于人的肝胆管内,人因吃了含囊蚴的生鱼而感染,成为泰国东北部重要的公共卫生问题,约有七百万人受染。麝猫后睾吸虫的流行区以及它的近亲华支睾吸虫的流行区,胆管癌的发病率亦高。此外,后睾吸虫感染还与几种无症状的肝胆异常有关,这些异常可用B型超声波发现,它包括左肝叶和胆囊的增大,胆囊收缩力的丧失、门静脉根部瘀积及超声异常。最近的研究表明了感染的强度和异常的程度有直接关系。本文观察了治疗后患者肝胆管的变化。
Opisthorchis viverrini is parasitic in the human hepatobiliary tract and infects humans as a result of eating raw fish containing metacercaria. It has become an important public health problem in northeastern Thailand, affecting about 7 million people. The prevalence of testis in Civet cat and its close relatives, Clonorchis sinensis, also have a high incidence of cholangiocarcinoma. In addition, post-testis infection is also associated with several asymptomatic hepatobiliary abnormalities that can be detected with type B ultrasound, including increased left hepatic lobe and gallbladder, loss of gallbladder contractility, portal vein root mass stasis and ultrasound abnormalities. Recent studies have shown that the intensity of the infection is directly related to the extent of the abnormality. This article looked at the change of the hepatobiliary tract in patients after treatment.
