Insights
Children with Down syndrome and Hirschsprung's disease often experience persistent bowel dysfunction, including incontinence and diarrhea. However, symptoms like constipation and fecal incontinence tend to improve with age in these patients.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Genetics
Background:
- Hirschsprung's disease (HSCR) is frequently diagnosed in children with Down syndrome (DS).
- The long-term bowel function and continence outcomes for children with co-occurring DS and HSCR remain poorly understood.
- This study investigates the natural history of bowel function in this specific pediatric population.
Purpose of the Study:
- To determine the natural history of bowel function in children diagnosed with both Down syndrome and Hirschsprung's disease.
- To assess the prevalence of continence issues and other bowel dysfunctions in this cohort.
- To identify potential factors influencing bowel function over time.
Main Methods:
- A retrospective study was conducted on patients diagnosed with both DS and HSCR.
- Data was collected from medical records at the Royal Children's Hospital, Melbourne, between 1974 and 2001.
- A structured questionnaire was used to gather information on bowel function and continence from eligible patients.
Main Results:
- Fecal incontinence was reported by 87% of patients, with 40% experiencing diarrhea and perianal excoriation.
- Persistent constipation was less common, affecting 20% of the cohort.
- A significant improvement in bowel dysfunction, including sensation, constipation, diarrhea, and excoriation, was observed with increasing age (P < 0.05).
- An unexpectedly high prevalence of adverse food reactions (90%), particularly to fruits and vegetables, was noted.
Conclusions:
- Children with Down syndrome and Hirschsprung's disease commonly experience persistent bowel dysfunction.
- Evidence suggests that bowel function, including continence, improves with age in this population.
- A high incidence of adverse reactions to food warrants further investigation in this patient group.
Background And Aim:
Hirschsprung's disease is more common in children with Down syndrome, but the outcome for continence in this group is unclear. The aim of the present study was to determine the natural history of bowel function in children with Down syndrome and Hirschsprung's disease.
Methods:
We undertook a retrospective study of all patients with both Down syndrome and Hirschsprung's disease diagnosed at the Royal Children's Hospital, Melbourne, between 1974 and 2001 using a structured questionnaire.
Results:
Ten of the 20 eligible patients were interviewed. Fecal incontinence was common (87%), as were episodes of diarrhea and perianal excoriation (40%). Persistent constipation was relatively unusual (20%). Adverse reactions to food, especially vegetables and fruit, were very common (90%). There was evidence that bowel dysfunction improved with age, particularly sensation of impending stool (P < 0.05), ability to discriminate stool consistency (P = 0.05), constipation (P < 0.05), episodes of diarrhea (P = 0.08) and excoriation (P < 0.05).
Conclusion:
Persistent bowel dysfunction is common in children with Down syndrome and Hirschsprung's disease, but there is evidence of improvement with age. There was an unexpectedly high prevalence of food-related adverse reactions.
