Multiple Transient Idiopathic Small Bowel Intussusceptions in an Adult: A Rare Intraoperative Finding

Adult small bowel intussusception is an uncommon clinical condition and is most frequently associated with a single pathological lead point. The occurrence of multiple synchronous small bowel intussusceptions in the absence of an identifiable cause is exceptionally rare and usually associated with Peutz-Jeghers syndrome. We report the case of a 32-year-old male who presented with persistent lower abdominal pain and was found on imaging to have a short-segment small bowel intussusception without evidence of ischemia. Diagnostic laparoscopy revealed multiple transient entero-enteric intussusceptions occurring at several locations along the small bowel, all of which reduced easily with manipulation; however, they would intussuscept with ongoing peristalsis. No pathological lead point was identified. The patient recovered uneventfully, and follow-up imaging demonstrated no small bowel lesions and no recurrence. This case highlights the diagnostic challenges and management considerations associated with idiopathic, multifocal adult small bowel intussusception.
