Anisakiasis usually occurs in the stomach and can easily be diagnosed by digestive tract endoscopy as opposed to enteric anisakiasis which is very rare and difficult to be diagnosed definitively. The most important and useful tool in diagnosing enteric anisakiasis is obtaining an accurate patient history of having eaten raw fish before the onset of symptoms. We report a case of small bowel obstruction caused by acute invasive enteric anisakiasis. A 60-year-old woman visited the emergency room suffering from sudden abdominal pain. She had eaten raw fish 1 day before the onset of symptom. Radiologic studies showed small bowel obstruction. However, no definitive cause could be found. An emergency laparotomy revealed edematous and dilated proximal jejunum and a focal stenosis of the distal jejunum. Segmental resection of the jejunum was performed, and histopathological examination revealed enteric anisakiasis. The patient was discharged on the 7th day after surgery following an uneventful course of recovery.
异尖线虫病通常发生在胃部，通过消化道内镜检查很容易诊断，而肠道异尖线虫病非常罕见，难以明确诊断。诊断肠道异尖线虫病最重要且有用的工具是在症状出现前获取准确的食用生鱼病史。我们报告一例由急性侵袭性肠道异尖线虫病引起的小肠梗阻病例。一名60岁女性因突发腹痛前往急诊室。她在症状出现前1天食用了生鱼。影像学检查显示小肠梗阻。然而，未发现明确病因。急诊剖腹探查发现近端空肠水肿、扩张，远端空肠有局灶性狭窄。对空肠进行了节段性切除，组织病理学检查显示为肠道异尖线虫病。患者在术后第7天顺利康复出院。
