title: Adult intussusception caused by Meckel's diverticulum complicated by anisakiasis of the small intestine: report of a case.
abstract: We report an extremely rare case of adult intussusception caused by Meckel's diverticulum complicated by anisakiasis of the small intestine. A 48-year-old female was admitted to our hospital with vomiting and abdominal pain 3 days after eating raw fish. The abdomen was distended with tenderness. Computed tomography demonstrated a target-shaped mass in the ileum and wall thickness of the distal ileum. We diagnosed intussusception and performed emergency surgery. At laparotomy, intussusception was already released. Since Meckel's diverticulum was observed at 40 cm and wall thickness was observed at 20 cm from the terminal ileum, we performed partial ileal resection including these lesions. On pathology, the anisakis body was found in the resected specimen of the ileum with wall thickness. The patient was discharged 8 days after surgery.
