Kim, Park, Park, Jeon, Jung, Son, Choi, and Kim: Anisakiasis Induced Segmental Jejunum Obstruction

Abstract

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.
