Jejunojejunal intussusception with internal herniation in the stomach.

Jejunojejunal intussusception with internal herniation of the stomach through a gastrojejunostomy stoma is one of the rarest complications of the previous gastric surgery. The incidence is reported to be less than 0.1 %. An elderly male presented to the emergency room with signs of intestinal obstruction for 1 day. There was also history of appearance of a lump in the mid-abdomen. A primarily healed midline scar of the previous surgery was present; the details of which were not known. X ray abdomen in the erect posture showed multiple air fluid levels. Ultrasonography (USG) revealed dilated stomach with central hyperechogenicity with a peripheral rim of decreased echogenecity. Contrast-enhanced computed tomography (CECT) scan showed jejunojejunal intussusception with internal herniation of the stomach. On laparotomy, it was found that there was a previous gastrojejunostomy with jejunal invagination leading to gangrene of a segment. Resection anastomosis was done. The postoperative period was uneventful.
