Abstract
We studied on clinical manifestations of possible anisakiasis intestinalis causing acute intestinal obstruction.
We have experienced 26 patients (males 22, females 4, mean age 42.4yr.) from January 1980 to March 1983. In 21 patients such episodes occured in winter and 21 patients had eaten raw fish within 2 days from the onset of the symptoms. The signs and symptoms were severe intermittent abdominal pain with slight vomiting, low grade fever and mild leukocytosis. In almost all cases eosinophilia occured within 2 weeks after the onset of the symptoms. X-ray revealed localized dilation of the small intestine. By conservative treatment for a few days all patients could be cured completely, so usually surgery is not necessary for the treatment.
For the diagnosis of possible anisakiasis intestinalis, signs and symptoms, clinical course and eosinophilia within 2 weeks after the onset are helpful.
