1/4. Splenic anisakiasis resulting from a gastric perforation: an unusual occurrence.

    We report a case of gastric perforation by anisakis sp. with consequent localization of the larva in the spleen. An 86-year-old white woman was admitted to our surgical department with a diagnosis of acute abdomen. She had a history of abdominal pain, and her laboratory data showed leukocytosis. In the plain abdominal radiograph, pneumoperitoneum was evident; a computed tomography (CT) scan of the abdomen confirmed the presence of extraluminal air. Anamnesis disclosed the ingestion of raw fish during the week preceding her illness. The patient was underwent emergency laparotomy. A small gastric perforation and a nodular area at the superior pole of the spleen were found. Surgical treatment was performed successfully and consisted of excision of the gastric lesion and splenectomy. The histological diagnosis revealed the presence of gastritis with an ulcer, and in the splenic tissue, some necrotic foci containing cross-sectioned degenerated worms compatible with anisakis larva.

2/4. anisakis infestation: a case of acute abdomen mimicking Crohn's disease and eosinophilic gastroenteritis.

    anisakiasis is a rare parasitic disease transmitted to humans by the ingestion of raw fish, which can initially present with acute abdomen. We report the case of a man, a habitual consumer of raw fish, who underwent surgery for acute abdomen, initially attributed to Crohn's disease and then later interpreted as eosinophilic enteritis. Only the subsequent careful histological examination of the surgical specimen, revealing full thickness eosinophilic infiltrate, generally typical of infestation, led to the detection of anisakis simplex larva. In cases of acute abdomen, in the presence of a positive history of raw fish ingestion, it is therefore reasonable to consider the possibility of anisakiasis.

3/4. Acute abdomen due to small bowel anisakiasis.

    The popularity in Western countries of dishes based on raw fish has led to an increased incidence of anisakiasis, a human parasitic disease caused by the ingestion of live anisakid larvae. The entire digestive tract may be involved, but the stomach and the small intestine are the most frequently affected sites. We report a case of acute abdomen due to anisakis simplex infection that caused small bowel obstruction.

4/4. Intestinal anisakiasis in italy: a case treated by emergency surgery.

    anisakiasis is a fish-borne zoonotic disease. A case of intestinal anisakiasis in a woman who had consumed raw marinated anchovies was reported. The intestinal localization resulted in occlusive acute abdomen which required an emergency surgical treatment. The histological examination of the eosinophilic granuloma removed from the resected colon revealed the presence of larval nematodes of the genus anisakis as causative agents.
