Two Cases of Gastric Anisakiasis Caused by Peudoterranova decipiens With Acute Abdominal Pain and Upper Gastrointestinal Bleeding
Abstract
- Human Anisakiasis is caused by the accidental human infestation of larvae of marine mammals. The larvae are usually introduced into human body by the intake of saltwater fish and squid. The common clinical symptoms are colicky pain, diffuse abdominal tenderness, nausea, vomiting, fever, and leukocytosis. Sometimes, they are severe enough to need acute abdominal surgery. The larvae invade the gastrointestinal mucosa, and occasionally result in upper gastrointestinal bleeding. Infestation by Anisakis type I is observed more often than that by Peudoterranova decipiens in Korea. The characteristic intestinal cecum which protrudes towards the ventriculus can be seen in Peudoterranova decipiens. While the characteristics of Anisakis type I and Peudoterranova decipiens are a little different, the clinical manifestation and treatment seem to be the same. We report two cases of gastric Anisakiasis caused by Peudoterranova decipiens larvae, which present acute abdominal pain and upper gastrointestinal bleeding.
