This paper deals with two cases of anisakiasis of the small intestine, which is rare, causing strangulated ileus in which emergency surgery was performed. Patient 1, a 37-year-old woman, was seen at the hospital because of epigastralgia and vomiting. Patient 2, a 57-year-old man, was seen at the hospital because of lower abdominal pain. Both patients were suspected to have strangulated ileus by abdominal CT scan and underwent emergency surgery. During surgery for the patient 1, we saw an induration with inflammation in the ileal wall which was adherent to the greater omentum to form a band, through where the small intestine herniated to be strangulated. In the patient 2, the ileum herniated through a band, which had been formed due to adhesions after an operation for appendicitis, and was strangulated there; an induration was found at part of the herniated ileal wall which had caused the herniation. Postoperative pathological studies disclosed larvae of family of Anisakidae in the indurations in both patients. Strangulated ileus caused by anisakiasis of the small intestine was definitely diagnosed.
