Anisakiasis is a parasitic disease acquired by humans when ingesting raw or undercooked fish infected with L3 larvae of the nematode genus Anisakis or Pseudoterranova. Here we report the first case of human anisakiasis in China. The patient, male, 56 years old, Dalian citizen, was admitted into the hospital with vomiting, peripheral umbilicus and abdominal distension, and frequent mucous diarrhea. The patient was examined using an electronic gastroscope, which displayed a parasite residing in the stomach, and subsequently gastroscope-assisted surgery was implemented. A white round worm was removed from the patient and stained. It was identified as L3 larvae of Anisakis. After the removal of the L3 larvae of Anisakis, the inflammation symptoms disappeared. As the first report of clinical case of Anisakis infection in China, the morphology of L3 Anisakis larvae from the patient is described and discussed. We conclude that anisakiasis should be considered in patients who have a habit of eating raw fish and who display associated symptoms.
异尖线虫病是一种人类因摄入感染了异尖线虫属或拟新地蛔线虫属L3期幼虫的生鱼或未煮熟的鱼而感染的寄生虫病。在此我们报告中国首例人类异尖线虫病病例。患者为男性，56岁，大连市民，因呕吐、脐周及腹胀、频繁黏液便入院。对患者进行电子胃镜检查，发现胃内有寄生虫，随后实施了胃镜辅助手术。从患者体内取出一条白色圆形线虫并进行染色。鉴定为异尖线虫L3期幼虫。取出异尖线虫L3期幼虫后，炎症症状消失。作为中国首例异尖线虫感染临床病例报告，对患者体内异尖线虫L3期幼虫的形态进行了描述和讨论。我们得出结论，对于有食生鱼习惯且出现相关症状的患者，应考虑异尖线虫病。
