Postoperative intussusception after surgery for malrotation and appendicectomy in a newborn.

Postoperative intussusception in the newborn is an infrequent condition. A 17-day-old female with duodenal stenosis and malrotation underwent excision of the membrane in the duodenum and incidental appendicectomy. Postoperatively, a ceco-colic type of intussusception occurred, necessitating a right hemicolectomy. We speculate that the causative factors are twofolds: the embedded appendiceal stump, a polyp-like protrusion that became a lead point, and the non-fixation of the ileocecal mesentery, which facilitated a ceco-colic type of invagination.
