• A case of small-bowel obstruction occurred secondary to an uncommon parasitic disease, anisakiasis. Intestinal obstruction is a rare manifestation of this disease. Anisakiasis may be seen initially with nausea and vomiting or may mimic acute appendicitis or Crohn's disease. The predisposing factor in all cases is the ingestion of raw fish, and the disease is preventable by cooking fish at greater than 60 °C for a short time or by freezing at less than −20°C for more than 24 hours. Anisakiasis should be considered in the differential diagnosis of small-bowel obstruction in patients whose diet includes raw fish.
