title: [Hirschsprung in children over 6 years of age].
abstract: BACKGROUND
  Hirschsprung's disease or colonic agangliosis is a rare condition in schoolchildren and adolescents. It is common in infants and chronic constipation is the usual symptom.
  
  
  RESULTS
  In a period of 5 years, 11-years-old patients were diagnosed and treated for Hirschsprung's disease. We studied six male patients; mean age was 8.6 years. All patients had classic disease and nine, severe chronic constipation, and two were admitted with encopresis. One had 10 kg of feces in 40 cm of colon. Diagnosis was established with barium enema and tissue biopsy. All patients had colostomy. In eight patients, Duhamel procedure was performed with good results.
  
  
  CONCLUSIONS
  This disease is a rare condition in older patients and Duhamel procedure is a good surgical option.
