Idiopathic proximal small bowel intussusception in an adult

Rationale: Intussusception is fairly uncommon in adults accounting for 5% of all intussusception cases and is a cause in 1% of intestinal obstruction cases. The condition is usually associated with a pathological lead point. Idiopathic intussusception is comparatively rarer in adults. Patient Concerns: 24-year-old male with right lower abdominal pain and intermittent loose stools for fifteen days. Diagnosis: Proximal small bowel intussusception. Intervention: Resection of the involved segment with primary jejunojejunal anastomosis. Outcome: Uneventful postoperative course and full recovery. Lessons: Idiopathic intussusception, though rare in adults, should be suspected in all adults presenting with non-specific abdominal pain particularly in absence of distinct abdominal signs. Management is surgical and usually entails resection of the involved bowel.
