 Anisakiasis is a disease caused by the migration of the third stage larvae of Anisakis or other related nematoda. This disease is divided into two types; gastric and intestinal type, each of which is further separated into fulminant (acute) and mild (chronic) form. It is known that the pathogenesis and clinical features differ among these types and forms.

 Anisakiasis was first reported by van Thiel in Netherlands. In Japan, Asami reported the first case in 1964. Since then, up to 1981, as many as 980 papers excluding ours have been published concerning this disease. In reviewing 1,823 cases of Japanese anisakiasis, 1,524 cases fell into gastric type and 223 into intestinal type, and the latter was predominantly of fulminant form.

 Preponderance of the gastric type seems to be explained by the fact that gastric type is easy to diagnose by using endoscope, while intestinal one is difficult to diagnose because it is not routine to use endoscope in the small intestine.

 Acute intestinal anisakiasis is characterized by acute ileitic condition, and most cases are found at emergency operation. Histological study shows that its acuteness is derived from the antigenecity of the parasite itself rather than eosinophil chemotactic factor released from it. So we conclude that this form represents re-infection of the parasite.
