Abstract

Postoperative intussusception in children is a rare but well recognized phenomenon. The diagnosis is often delayed due to the protean manifestations of the disorder (ileus, distention, and nausea and vomiting) which, when encountered shortly after an abdominal operation, usually result in a low index of suspicion because they are common after laparotomy. Experience with two cases of postoperative intussusception within 24 hours heightened our index of suspicion. Review of our records indicated we had diagnosed and treated postoperative intussusception in 14 children during the preceding 4 years. Patient ages ranged from 4 months to 12 years (mean 39 months, median 20 months), and symptoms appeared on postoperative days 3 to 36 (mean 10 days, median 6 days). Initial operations included excision of a retroperitoneal or abdominal tumor (five cases), Nissen fundoplication and gastrostomy (three), ileal resection (two), Ladd procedure (one), Duhamel operation (one), and operative reduction of ileocolic intussusception (the two most recent cases). Eleven patients had appendectomy (five by the inversion technique), and three had placement of a transgastric small bowel feeding tube. Nine children had had either barium enema or upper gastrointestinal studies because of the postoperative suspicion of obstruction; one patient had both. Diagnostic studies were not done in four patients. Operative reduction was successful in all but one child, who required bowel resection.
