An unusual intestinal infection with the parasite Metagonimus yokogawai was acquired by an American traveling in the Orient. Diarrhea began abroad, and recurred at intervals until she was seen 1 1/2 years later. Stool examinations resulted in the recovery of small operculated ova characteristic of intestinal or biliary fluke infection. Treatment with hexylresorcinol failed to eradicate the infection, but subsequent use of tetrachloroethylene was successful and facilitated recovery of adult parasites, leading to the specific diagnosis of metagonimiasis. Metagonimiasis and related intestinal fluke infections should be considered as a possible cause of persistent diarrhea in travelers returning from endemic areas abroad.
一名前往东方旅行的美国人感染了一种不寻常的肠道寄生虫——横川后睾吸虫。腹泻在国外就已开始，此后间歇性复发，直到1年半后就医。粪便检查发现了具有肠道或胆管吸虫感染特征的有小盖的虫卵。用己基间苯二酚治疗未能根除感染，但随后使用四氯乙烯成功治愈，并使成虫得以恢复，从而确诊为后睾吸虫病。后睾吸虫病及相关的肠道吸虫感染应被视为从国外疫区返回的旅行者持续腹泻的可能病因。
