The infection status of anisakid larvae was examined in 290 marine fish of 25 species and in 108 cephalopods of 3 species purchased in Bayuquan region, Yingko city nearby the coast of the Bohai Sea from may to August 1992. A total of 7,327 larvae were collected from 156 fish of 19 species and 8 squids of one species. The 3rd-stage larvae of Anisakis simplex were collected from 121 fish (63.4%) of 15 species (N = 191) and from 8 squids (14.8%) of one species (N = 54), and they were total, 5,992 (81.8%). Out of remaining 1,335 larvae, 154 (2.1%) were classified as Thynnascaris type B from 23 fish of 4 species, 1,013 (13.8%) as Thynnascaris type C from 79 fish of 13 species. 164 (2.2%) as Hysterothylacium China type V from 20 fish of 4 species, 3 (0.04%) as Raphidascaris from 3 fish of 2 species and one was Pseudoterranova decipiens larva.

BACKGROUND/AIMS: The thickened gastric wall are seen in a great number of benign and malignant conditions. Sometimes the differential diagnosis with either upper gastrointestinal X-ray or endoscopy of those lesions is difficult. We evaluated the usefulness of the endoscopic ultrasonogrphy (EUS) in the differential diagnosis for the thickened gastric wall of benign and malignant lesions. METHODS: Fifty Borrmann type 4 advanced gastric cancers, 7 gastric lymphomas, 4 hypertrophic gastropathies, 3 acute gastric mucosal lesions, and one anisakiasis were included. We measured the full thickness of the gastric wall, the thickness of each layer and the preservation of the five-layered structure of the gastric wall, and then compared them with the endosonographic findings of 11 healthy controls. RESULTS: Endosonographic findings of Borrmann type 4 advanced gastric cancers showed a diffuse thickening of all five layers, especially the third and fourth layers. Endosonographic findings of gastric lymphomas showed enlargement of the second, third, and fourth layers in 4 patients, the second and third layers in 1 patient, and only the second layer in 2 patients. The second layer was thickened in hypertrophic gastropathies, the second and third layers were thickened in acute gastric mucosal lesions, and the third layer was thickened in anisakiasis. The fourth ultrasound layer corresponding to the muscularis propria was significantly thickened only in malignant lesions. CONCLUSIONS: EUS can clearly visualize the wall architecture of the thickened gastric wall. EUS may be useful for the differential diagnosis of the thickened gastric wall and the differentiation of benign from malignant gastric lesions.

Anisakiasis is a rare finding in the colon in comparison with its involvement in the stomach. Also, anisakiasis of the colon is usually incidentally diagnosed during either endoscopy or on operation for intestinal obstruction due to the fact that anisakiasis of the colon does not have typical clinical features. In other words, the diagnosis of colonic anisakiasis is usually made after surgical exploration. We herein report on two cases of anisakiasis of the colon that were treated successfully by colonoscopic removal of the worm without any surgery. A review of the related literature is included.

Eosinophilic enteritis is characterized by massive infiltration of eosinophil throughout the entire or each layer of intestinal wall with marked submucosal edema. The etiology of this disease is not clear until now, and parasite infestation should be considered as a cause of eosinophilic enteritis like this case. We experienced a case of eosinophilic enteritis manifested by intermittent periumbilical pain and bloody ascites. After partial resection of ileum, we confirmed the eosinophilic abscess from Anisakis infestation and successfully treated this patient without sequalae and report it with literatures review.

BACKGROUND AND AIMS: When acute gastric anisakiasis is clinically suspected, endoscopic removal of larva is the only definite treatment method. However, there has been little known for endoscopic findings of gastric anisakiasis. METHODS: In 39 patients with gastric anisakiasis, the ingested species of marine products and clinical findings were investigated. The form of larvae, the mucosal changes of the insertion site, close and distant area were also analysed during endoscopic examination. RESULTS: Twelve patients (30.8%) ate raw Astroconger myriaster solely, and the most frequent mucosal insertion site of larvae was around the greater curvature of the body (59.5%). Endoscopic findings of erosion (33.3%), hemorrhagic erosion (33.3%) and redness of the mucosa (11.9%) were observed at the insertion site. The adjacent mucosal changes were edema and fold enlargement. All patients were treated medically. CONCLUSIONS: When acute gastric anisakiasis is suspected, the careful endoscopic examination of larva was necessary for confirmatory diagnosis and definite treatment of the disease.

Anisakiasis is a disease caused by human infection by the Anisakis larvae, a marine nematode found in raw or undercooked fish. Most of anisakiasis are found in gastric or intestinal mucosa, but Anisakiasis in the oral cavity is rare. So, we elaborate on it in the present report with a review of literatures. This is the first report about anisakiasis of oral cavity in the recent literatures in Korea.

Human anisakiasis is a disease caused by an infestation of the third stage larvae of family anisakidae. The ingested larvae invade the gastrointestinal wall, causing clinical symptoms that include abdomen pain, nausea, and vomiting. Although enteric anisakiasis is extremely rare, it can induce intestinal obstruction. We report a case in which emergency surgery was needed due to intestinal obstruction that coincided with symptoms related to anisakiasis, along with a brief literature review.

BACKGROUND/AIMS: Although the overall infection rate of infection with parasites has decreased, the rate of food-mediated infection with parasites has not declined. This study was conducted to define the various endoscopic and clinical characteristics of gastrointestinal (GI) parasite infections diagnosed endoscopically. METHODS: We reviewed retrospectively the medical records including the endoscopic reports of 27 patients with GI parasite infections diagnosed endoscopically at University Hospital from January 1993 through September 2006. RESULTS: Among 27 patients with a GI parasite infection, 66.7% were female and food-mediated parasite infections including anisakiasis accounted for 77.8% of all of the infections. Soil-mediated parasites were still detected. Extremely rare cases of echinostomiasis and diphyllobothriasis were also identified. Abdominal pain was most frequent symptom (48.1%) and even intestinal or biliary obstructions were seen. The most common endoscopic finding was a visible worm, and various findings including the presence of a pseudotumor were observed. The median period from symptom onset to endoscopy was 15 days for anisakiasis with a pseudotumor compared to 1 day for anisakiasis without a pseudotumor. CONCLUSIONS: Endoscopy revealed the presence of various GI parasite infections as well as the presence of anisakiasis, a food-mediated parasitic disease. Various clinical and endoscopic features were seen, including GI bleeding, obstruction, and a pseudotumor. Therefore, a thorough endoscopic examination is required promptly together with detailed history taking concerning the consumption of raw fish.
