Abstract:
BACKGROUND AND AIMS: When acute gastric anisakiasis is clinically suspected, endoscopic removal of larva is the only definite treatment method. However, there has been little known for endoscopic findings of gastric anisakiasis. METHODS: In 39 patients with gastric anisakiasis, the ingested species of marine products and clinical findings were investigated. The form of larvae, the mucosal changes of the insertion site, close and distant area were also analysed during endoscopic examination. RESULTS: Twelve patients (30.8%) ate raw Astroconger myriaster solely, and the most frequent mucosal insertion site of larvae was around the greater curvature of the body (59.5%). Endoscopic findings of erosion (33.3%), hemorrhagic erosion (33.3%) and redness of the mucosa (11.9%) were observed at the insertion site. The adjacent mucosal changes were edema and fold enlargement. All patients were treated medically. CONCLUSIONS: When acute gastric anisakiasis is suspected, the careful endoscopic examination of larva was necessary for confirmatory diagnosis and definite treatment of the disease.
