Aspects of Mucosal Changes in Gastric Anisakiasis
Acute gastric anisakiasis caused by mucosal penetration of Anisakis larvae is fairly common in Japan as many species of fish, including mackerel, are often eaten raw [1–3]. Hence in patients with acute epigastric pain, anisakiasis should always be considered.
As the larvae of Anisakis present in the gastric mucosa can be observed endo-scopically, extraction is for the most part feasible . The clinical features and characteristic findings at endoscopy and in upper gastrointestinal tract series plus the mucosal changes in gastric anisakiasis are described in this chapter.
