Ileocolic Invagination in Adults: A Totally Minimally Invasive Endoscopic and Laparoscopic Staged Approach

Adult intussusception of the bowel is a rare clinical entity, and its management remains debated. The timing of treatment is not yet standardised, and no guidelines exist. We report a case of an 83-year-old woman presenting to the emergency department of our hospital with a history of increasing abdominal pain in the right iliac fossa. A contrast-enhanced computed tomography scan showed the presence of a large ileocolic intussusception with evidence of the terminal ileus invaginated within the right colon and the ileocolic vessels dragged and trapped into the intussusception. A colonoscopy confirmed the ileocolic invagination with a large right colonic lesion as leading point, and a partial pneumatic (carbon dioxide) and hydrostatic reduction was achieved. Subsequent laparoscopic right colectomy was performed according to oncological principles. A totally minimally invasive approach of this rare condition has been achieved but the literature lacks about the correct management of this entity.
