ACUTE GASTRIC ANISAKIASIS - 28 CASES DURING THE LAST 10 YEARS

Anisakiasis is a disease which occurs following eating raw fish infect ed with anisakis larvae. Many cases have been reported from Japan and from other countries with increasing opportunities of eating raw fish such as ''sushi'' and ''sashimi.'' We have reviewed 28 patients with a cute gastric anisakiasis during the last 10 years from November 1984 t o October 1994. This disease has rarely been detected in persons over 60 years of age and in patients with gastric surgery. Therefore it is postulated that gastric acid secretion influences the activities of an isakis larvae. An alkaline gastric pH could interfere with the toxicit y of anisakis larvae.
