Laparoscopic treatment for an inflammatory fibroid polyp complicated with ileocecal intussusception: a case report and literature review.

Introduction and importance: Adult intussusception is a rare clinical entity, accounting for less than 5% of all cases and often associated with an underlying lesion. Inflammatory fibroid polyps (IFPs) are rare benign mesenchymal tumors that may act as a lead point for intussusception, most frequently in the small intestine. Herein, we report the case of a 52-year-old woman presenting with ileocecal intussusception secondary to an IFP. Case presentation: A 52-year-old woman presented with intermittent abdominal pain and symptoms of subacute obstruction. Imaging revealed an ileocolic intussusception due to a polypoid ileal lesion. Laparoscopic ileocecal resection was performed with primary ileocolic anastomosis. Histopathological analysis confirmed the lesion as an inflammatory fibroid lesion. The postoperative course was uneventful, corresponding to Clavien-Dindo Grade 0. The patient remained symptom-free at 6 months of follow-up. Clinical discussion: IFPs most often arise in the stomach and small intestine. In the small bowel, IFPs can serve as a lead point for intussusception, but ileocecal presentations remain uncommon. The laparoscopic approach is safe and provides excellent visualization and is associated with reduced pain and faster recovery. Complete resection of IFPs is curative with rare recurrence rates. Definitive diagnosis relies on histopathology and immunohistochemistry. Conclusion: This case highlights the diagnostic challenges of adult intussusception, particularly when imaging is inconclusive. IFPs should be considered as a differential diagnosis. Moreover, it underscores the importance of laparoscopic surgical management both for diagnostic and therapeutic purposes.
