A Case of Gastric Anisakiasis Causing Mallory - Weiss Syndrome / 대한소화기내시경학회지

Anisakiasis is an infection in humans caused by larval nematodes of the family Anisakidae and is encountered in people who eat inadequately prepared raw, salt-water fish or "sashimi". This clinical syndrome is characterized by severe cramping abdominal pain, nausea, and vomiting. Because Koreans like to eat raw fish, anisakiasis of the stomach has been reported occasionally, but the incidences of upper gastrointestinal bleeding caused by anisakiasis has been very rare. The present case is a 30 year-old male Admitted with an episode of hematemesis. A gastrofibroscopy revealed a mucosal laceration and the larva of Anisakis on the esophagogastric junction. We report one case of Mallory-Weiss Syndrome due to gastric Anisakis larva, confirmed by an endoscopy.

A Case of Lymphatic Metastasis to Ampulla of Vater from Gastric Adenocarcinoma / 대한내과학회지

Cancer of the stomach is responsible for approximately 650,000 deaths globally each year and is probably second only to lung cancer worldwide as an overall cause of cancer-related mortality. Similar to the situation with most adenocarcinomas of the gastointestinal tract, carcinomas of the stomach can spread by local extension to adjacent normal structures and can develop lymphatic, peritoneal, and distant metastases. The tumor cells, can also permeate diffusely into the lymphatic plexus of the bowel, more often at the level of the upper duodenum hut sometimes down into the distal ileum and the large bowel. We report a case of lymphatic metastasis of gastric adenocarcinoma to the ampulla of Vater with review of the literature.

A Case of Strongyloides Stercoralis Infection Associated with Long-term Adminstration of Steroid in a Patient with Alcoholic Liver Disease / 대한소화기내시경학회지

Strongyloides stercoralis is distinguished by a capacity, unusual among helminths to replicate within the human host, thereby permitting on going cycle of autoinfection due to internal production of internal larvae. It has a worldwide distribution but is much more common in tropical climates where the warm, moist soil offers an environment suited to the development of the larvae. In immunocompromised hosts who receiving corticosteroids, immunosupressive drugs, or radiotherapy in these with AIDS, large numbers of invasive strongyloides larvae can disseminate widely and be fatal. The presents case is a 76 year-old-woman presenting with vomiting and epigastric pain. The patient had a long history of adminstration of steroid and alcohol. A gastrofibroscopic biopsy and stool examination revealed rhabditoid larvae. The patient seems to have suffered from autoinfection with S. stercoralis. We report this case with the review of literatures.
