[Clinical study of ileus like symptom due to eating of raw firefly squid, Watasenia scintillans].
We report 12 patients who ate raw firefly squid, Watasenia scintillans. The patients experienced abdominal pain one or two days after eating them. Ileus was suspected by abdominal X-ray, but abdominal muscle guarding was not recognized. No specific findings was revealed on laboratory data. Patients were recovered two or three days after admission by only drip infusion. Recently, type X larva of the suborder Spirurina is recognized in 3.3% of firefly squid viscus. Indirect fluorescent antibody test using antigen of the type X larva was evaluated for the sera of the 8 ileus patients who were admitted in 1993. The antibody titers were positive in 5 patients and were negative in 3 patients. These results suggested that the ileus like symptom we reported here was attributed to the type X larva of the suborder Spirurina.
