总结
在2例急腹症患者胃内嗜酸性肉芽肿中发现长度超过2厘米的幼虫线虫。根据与抹香鲸上鉴定为未成熟异尖线虫属的蠕虫的形态比较，1例的幼虫被鉴定为异尖线虫属，而另一种被鉴定为不同但密切相关的物种。幼虫的显著特征是延伸到体腔内的大Y形侧线，以及形成肠壁的许多高柱状上皮细胞，以及沿食道和肠上部沿着的大腺体样器官。
据推测，感染是通过吃生鱼获得的，这是日本人普遍的习俗。预计在出现急腹症症状的日本患者中可能会发现类似病例。
Summary
Larval nematodes more than 2 centimeters in length were found in eosinophilic granulomas in the stomach of two patients suffering from acute abdominal symptoms. On the basis of morphological comparison with worms identified as immature Anisakis sp. from the sperm whale, the larva of one case was identified as Anisakis sp., and that of the other was identified as a different but closely related species. Striking features of the larvae were large Y-shaped lateral chords extending into the body cavity, and numerous, high columnar epithelial cells forming the wall of the intestine as well as a large gland-like organ along the esophagus and upper intestine.
The infections presumably were acquired by eating raw fish, a custom that is widespread among the Japanese. It is expected that similar cases may be found among Japanese patients presenting with acute abdominal symptoms.
