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. Postoperati
vely, a ceco-colic type of intussusception occurred, necessitating a right
hemicolectomy. We speculate that the causative factors are twofolds: the em
bedded 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.
