The clinical symptoms are cramping abdominal pain, nausea, vomiting, diarrhea, tarry stool, and epigastric fulling sensation. We experienced six cases of acute gastric Anisakiasis and one case of duodenal Anisakiasis and all patients had a history of ingestion of raw sea fish and squid as "sashimi". Immediate endoscopic examination showed the whitish linear worm on stomach or doudenal bulb. Clinical symptoms was improved after removal by biopsy forcep.
