The most frequent symptom of gastric anisakidosis was epigastric pain. But symptoms of intestinal anisakidosis were variable. Anisakis allergic patients showed abdominal pain and urticaria symptom in common.
The anisakids were most frequently located in the stomach, followed by colon and small intestine. The most obvious change was the appearance of allergy patients since 2006. Allergic cases failed to find larva with gastrofiberscopy, although all patients had eaten raw fish. But they showed specific IgE response to A. simplex antigen.
Sea eels and squid were still the most common species to cause infection. In more than half of the cases, however, the Anisakis species could not be identified. The identified anisakid species was almost Anisakis species, except 3 cases which were diagnosed to Pseudoterranova species. The species identification was not available in allergic cases and some eosinophilic granuloma cases.
The gastrofiberscopy was the most widely used tool in anisakidosis. The colonoscopy was also applied frequently in intestinal anisakidosis. The treatment was accomplished simply by removing the worms in 19 cases, followed by a resection of affected lesion. No treatment was done in allergic cases.
*All six cases diagnosed stomach involvement showed epigastric pain.
