OBJECTIVES: To identify the endoscopic findings and clinical manifestations of anisakiasis, we studied 87 cases of gastric anisakiasis. METHODS: Patient information was analyzed by means of patient records. The interval between the day of intake of Anisakis and endoscopic examination was determined in 86 cases. Then the endoscopic findings of each interval were elucidated. RESULTS: Moderate to severe gastric mucosal edema tends to occur within 1 or 2 days after Anisakis infection, accompanied by leukocytosis. As to the sites of penetration of Anisakis, 55% of cases were found in the greater curvature with severe mucosal edema. Among 87 cases, four patients experienced anisakiasis twice during the interval examined, and six patients had past histories of anisakiasis before the investigated interval. CONCLUSIONS: Gastric anisakiasis may be caused by an allergic reaction to the Anisakis antigen. There is a classic relationship between clinical and endoscopic findings and the interval after Anisakis administration. Anisakis usually is found in the greater curvature.
