Abstract

Adult intussusception is rare involving of only 1% of the causes of bowel obstruction. We report a case of a 39-year-old female with intussusceptions due to inverted Meckel's diverticulum. She visited our hospital for diffuse abdominal pain during 1 week and aggravated abdominal pain for 2 days. Vital signs were stable, and there was periumbilical tenderness. She had no history of abdominal operation. CT scan showed a 3.7x2.1 cm of fatty mass with focal intussusception in the distal ileum. When the emergency operation was performed, the patient was found to be suffering from ileocolic intussusception. A manual reduction of intussusception showed inverted Meckel's deverticulum at 65 cm proximal to the ileocecal valve, and the segmental resection of small bowel including a Meckel's diverticulum was performed. Pathologic examination revealed a Meckel's diverticulum containing a 0.6x0.6 cm sized aberrant pancreas.

  Fig. 1 CT scan shows fatty mass with focal intussusception in the distal ileum.

  Fig. 2 Operative findings. (A) An ileoileal intussusception is noted. (B) After manual reduction of the intussusception, Meckel's diverticulum is found with a yellow colored soft mass on the tip.

• 

  Fig. 3 Histologic findings. (A) The mucosal layer is composed of gastric, colonic or small intestinal mucosa. And the proper muscle layer is also found (H&E stain, ×40). (B) In the subserosal area, pancreatic tissue is noted forming round aggregate approximately 1.0×1.0 cm in size. The pancreatic tissue is composed of ductal epithelium and scattered clusters of endocrine cells in the fibrotic background (H&E stain, ×100).
