  ABSTRACT: Introduction: Jejunojejunal intussusception is rare in adults. Peutz-Jeghers syndrome is one of the etiologies in young adults. Case Report: This was a 19-year-old patient admitted to the Emergency Department of Saint Louis Hospital in La Rochelle with a clinical presentation of bowel obstruction, characterized by sudden-onset severe abdominal pain and vomiting. On examination, an abdominal mass was palpable in the left periumbilical and epigastric regions, with guarding. Abdominopelvic computed tomography revealed a large jejunojejunal intussusception without signs of ischemia. Surgical exploration by laparotomy showed that the intussusception was located approximately 50 cm from the duodenojejunal flexure. Reduction was performed, followed by surgical resection of 75 cm of jejunum with a mechanical side-to-side anastomosis. The postoperative course was uneventful, and histological examination of the surgical specimen concluded that the lead point was a Peutz-Jeghers hamartomatous polyp. Rationale: Limited data are available in France on adult intestinal intussusception. The report highlights an important benign lead point to consider in young adults with small-bowel intussusception.
