The intraoperative findings showed a small bowel tight intussusception of the biliary limb into the enteric limb with full-thickness necrosis (Fig. 1).
Gross appearance of the resected specimen showing the thickened segment of the small bowel (intussusceptum) on the right side and the dilated part (intususcepiens) on the left side. A hemorrhagic polyp which is partly removed for microscopic examination, is seen at the junction between the thickened and dilated segments. The mucosa is hemorrhagic and the external surface is covered by fibrinoinflammatory exudate indicative of acute peritonitis.
