A case of abdominal syndrome caused by the presence of a large number of Anisakis larvae.

A 58-year-old woman living in Shizuoka Prefecture, Japan, complained of severe epigastric pain and nausea about 8 h after having eaten 'Sashimi'. A gastrocamera examination undertaken as a result of her clinical history of gastric anisakiasis indicated that a large number of worms had penetrated the posterior walls. Fifty-six larval nematodes were directly removed from the greater curvature of the stomach with a gastroendoscopic biopsy clipper, and were identified as the larvae of Anisakis simplex.
