A rare case of ileo-ileal intussusception due to a bleeding lipomatous mass treated by laparoscopic ileal resection.

Introduction: Adult intussusception is a rare cause of bowel obstruction with atypical presentation. It can be associated with primary or secondary intestinal tumors and, rarely, with lipomatous masses.

Case Report: We report the case of a 69-year old man presenting with a history of gastrointestinal bleeding and anemia. Upper and lower endoscopies were negative for bleeding. On abdominal contrast enhanced computerized tomography (CT) scan, a trans-omental hernia in the right lower abdominal quadrant was diagnosed with no active bleeding or evidence of tumor. On exploratory laparoscopy we detected an ileo-ileal intussusception caused by a submucosal mass in the distal ileum, which was reduced and we then performed a segmental resection of the involved small bowel tract. The patient fully recovered by postoperative day 3 when he was discharged home. Final pathology confirmed an ileal lipoma.

Conclusion: Ileal intussusception caused by lipoma is a rare condition, which can be diagnosed with endoscopy, barium enema, and abdominal ultrasound or CT scanning, but preoperative diagnosis may be difficult. The treatment of choice is the reduction of the intussusception and the resection (laparoscopic or open) of the involved tract.
