“…More than half of the larvae were identified in the greater curvature of the stomach body. These findings support the previous report that Anisakis prefer to penetrate into the mucosa in the greater curvature (13,14). The reason for this preference is unknown, however, the gastric mucosa in the greater curvature may provide a good environment for larvae to penetrate the gastric wall.…”

Multiple Acute Infection by <i>Anisakis</i>: A Case Series

et al. 2016

The ingestion of raw seafood infected with nematode larvae of the Anisakidae family can lead to gastric anisakiasis. The majority of the infections involve a single larva, however, there have been instances of multiple infection. The incidence rate and the characteristics of multiple infection by Anisakis remain poorly understood. We herein present a case of parasitization by multiple Anisakis larvae and describe 14 cases of multiple parasitization representing the largest reported case series to date. Endoscopists should therefore be aware of the potential for multiple infection by Anisakis and the need for a thorough inspection of all parts of the stomach when encountering such cases.

“…Most reports on anisakiasis have indicated that the most frequent parasitic location was the greater curvature of the gastric lower, mid and upper body. The reason for the recovery of worms primarily from the greater curvature is not clear, but Shibata et al [ 9 ] noted that the great curvature provides a good environment for the Anisakis larvae to penetrate the gastric wall, due to the large number of folds and the more active secretion of mucus in this region. In the present case, the SMT was also distributed over the greater curvature of the gastric midbody.…”

Chronic gastric anisakiasis provoking a bleeding gastric ulcer

2014

View full text Add to dashboard Cite

Gastric anisakiasis is a parasitic disease caused by the gastric mucosal penetration of the Anisakis larvae ingested with raw fish. Acute gastric anisakiasis is diagnosed by the endoscopic visualization of Anisakis larvae along with mucosal edema, erythema, hemorrhage, and/or an ulcer, whereas chronic anisakiasis is often observed as a localized tumor commonly occurring in the submucosal layer, and is characterized by eosinophilic granuloma with edema and embedded Anisakis larvae on pathological examination of surgical specimens. We report here a case of chronic gastric anisakiasis provoking a bleeding gastric ulcer, which is a rare clinical manifestation of this condition.

“…The reason why the worms are recovered primarily from the great curvature is not clear. Shibata et al (1989) noted that the great curvature provides a good environment for anisakid larvae for penetrating the gastric wall, due to the large number of folds and the more active secretion of mucus in this region.…”
