Abstract

<p>A 70-year-old woman was admitted to our hospital with acute abdominal pain and vomiting, 2 days after she ate raw bonito. Contrast-enhanced abdominal computed tomography revealed the nearly pathognomonic target sign of intussusception in the ascending colon, with a thickened wall of the terminal ileum, an elevation in fat density, and fluid collection around the ileocolic region. We diagnosed the patient with ileocolic intussusception secondary to suspected ileal anisakiasis. Using a colonoscope, we performed successful endoscopic reduction of the intussusception and removed an Anisakis larva using endoscopic forceps. Her symptoms rapidly improved after endoscopic repositioning of the intussusception, and invasive surgery could be avoided.</p><p>Intussusception secondary to small intestinal anisakiasis is rare. To our knowledge, this is the first case report that describes successful conservative treatment of ileal anisakiasis-induced intussusception, following endoscopic intussusception reduction and removal of the Anisakis larva.</p>
