MANAGEMENT OF HIRSCHSPRUNGS-DISEASE IN CHILDREN WITH TRISOMY-21

Thirteen infants and children with trisomy 21 have been treated for Hirschsprung's disease since 1975. Clinical presentation of Hirschsprung's disease included constipation (five); neonatal intestinal obstruction (four); enterocolitis (three); and meconium plug syndrome (one). Additional associated congenital anomalies occurred in 10 patients, of which complex cardiac disease accounted for 25% of the defects. Seven children underwent definitive operation: Duhamel pull-through (four); Soave pull-through (two); and anal myectomy (one). Satisfactory continence occurred in all but one child. Enterocolitis developed in seven patients (54%): two at diagnosis of Hirschsprung's disease; three after colostomy; and two after pull-through. Five children died (38%): one from enterocolitis, two from cardiorespiratory failure after recovery from enterocolitis, and two from end-stage cardiac disease. Children with trisomy 21 can safely undergo definitive operation for Hirschsprung's disease but are at high risk for developing enterocolitis and complications of associated cardiac disease. © 1990 Reed Publishing USA.
