[Postoperative intussusception in children].

The authors present diagnosis and treatment of two children with postoperative intussusception. A 6-month baby with retroperitoneal teratoma developed clinical signs of intestinal obstruction in 2 days after surgery. The child underwent redo laparotomy, and ileocecal intussusception was found. In the second case, a 6-month baby with choledochal cyst underwent laparotomy, cyst excision and Roux-en-Y-hepaticojejunostomy. Six days later, clinical deterioration with signs of bowel obstruction appeared. Redo laparotomy was performed for early adhesive ileus, and ileoileal intussusception was observed. In both cases, postoperative intussusception was diagnosed during relaparatomy that confirms the complexity of diagnosis.
