Unanticipated death from enterocolitis occurred in five children 3 wee
ks to 20 months after uncomplicated reconstruction for Hirschsprung's
disease. In each case the presenting symptoms of enterocolitis were mi

rocolitis is a well-known complication of Hirschsprung's disease, emph
asis is usually placed on preoperative enterocolitis. Fatal postoperat
ive enterocolitis is not a new entity associated with Hirschsprung's d
isease, but physician awareness of this possibility is obviously defic
ient. We strongly recommend extensive parent education and better post
operative communication between the surgeon and the referring physicia
