Laparoscopic operation after pre-operative reduction of an intussusception-induced inflammatory fibroid polyp.

Intussusception occurs mainly in children but rarely in adults. About 80-90% of adult cases of intussusception are due to benign or malignant neoplasms as a lead point. One of the causes is an inflammatory fibroid polyp (IFP), a rare, benign entity that occurs more frequently in the stomach than the ileum. We describe an uncommon case of a patient who presented with intussusception-induced IFP of the ileum. A 35-year-old woman presented with a 2-day history of abdominal pain. A computed tomography scan demonstrated ileocolic intussusception. During colonoscopy, reduction by pressured air easily released intussusception, and we suspected a submucosal tumour of the ileum. Successful pre-operative colonoscopic reduction was helpful for performing laparoscopic ileocecal resection 2 days later. Results of the histopathological examination confirmed a large IFP. The patient's post-operative course was uneventful. Pre-operative reduction by colonoscopy is effective for the diagnosis and treatment of intussusception-induced IFP.
