Gastrointestinal manifestations and management of anisakiasis.

Anisakiasis is a parasitic disease of the gastrointestinal tract acquired by ingestion of raw fish containing stage 3 larvae. In the present report, we describe a patient who frequently ate raw fish who presented with acute onset of epigastric abdominal pain and a peripheral blood eosinophilia. His symptoms resolved with endoscopic removal of the nematode. Given the increasing consumption of raw fish in Western cultures, anisakiasis should be considered in patients with abdominal pain and a history of raw fish consumption.
