Anisakiasis in the Upper Esophagus: A Case Report.

Anisakiasis is caused by consuming raw fish contaminated with Anisakis sp. larvae and is extremely rare, especially when originating in the esophagus. We present a case of esophageal anisakiasis in a 61-year-old male who experienced severe precordial pain and radiating discomfort to the neck after consuming raw fish sashimi. Upper gastrointestinal endoscopy revealed the presence of a larva in the upper esophagus. On the basis of anatomo-morphological features, the worm was provisionally identified as Anisakis sp. and was easily extracted with forceps, which led to a prompt improvement in the patient's symptoms. This case highlights the importance of considering anisakiasis as a differential diagnosis in patients with gastrointestinal symptoms and a history of consuming raw fish.

A Case of Esophageal Anisakiasis Presenting as Chest Pain Mimicking Angina / 대한소화기내시경학회지

Chest pain of a non-cardiac origin is frequently seen in medical practice. This kind of chest pain is often difficult to differentiate from chest pain of a cardiac origin. Esophageal anisakis is a rare finding, but it can cause chest pain. We report here on a patient who had a history of acute myocardial infarction and who also had one stent inserted in his left anterior descending coronary artery two month previously. The patient presented with substernal chest pain that mimicked anginal chest pain. Endoscopic examination revealed a whitish linear worm that had had invaded the esophagogastric junction, and we removed the worm with biopsy forceps. We report here on a patient with an esophageal anisakiasis as a rare cause of noncardiac chest pain that mimicked anginal chest pain.

A Case of Anisakiasis Concurrently Invading Esophagus and Stomach, and Another Case of Esophageal Anisakiasis / 대한소화기내시경학회지

Human anisakiasis may occur after ingestion of raw marine fish infected with the nematode larvae of Anisakidae. Clinical symptoms such as cramping abdominal pain, nausea, vomiting, diarrhea and epigastric fullness, usually develop within 12 hours after having eaten infected raw sea fish. Anisakiasis is most commonly found in the stomach, and is rarely identified in the small intestine, large intestine, and esophagus. We report two cases of of anisakiasis, one with concurrent invasion of the stomach and esophagus, and the other case with esophageal anisakiasis. Both were treated by endoscopic extraction of the larvae.
