Postoperative intussusception is an uncommon but serious condition in infants and children.Here,we report seven cases of postoperative intussusception in infants and children who were seen at our institution over the last 13 y.The patients showed increased nasogastric drainage,vomiting,lack of stool,and/or growing abdominal distension 2 to 9 d following abdominal surgery.Manual reduction was successful in five cases.In two cases,necro-sis was found and intestinal resection and anastomosis were carried out.No recurrence was observed at six months of follow-up.Postoperative intussusception should be suspected in pediatric surgical patients who showed signs of intestinal obstruction in the early postoperative period.
