Brief Summary
Hirschsprung's disease is a complex genetic disorder. The etiology of this disease is not completely understood. It is characterized by the absence of ganglia (nerve cells) in de distal colon. This impairs bowel relaxation which can lead to bowel disfunction, toxic megacolon, ileus and enterocolitis. So far, several genes have been identified that play a role in Hirschsprung's disease. The precise mechanisms however, remain unclear. This study wants to identify new mutations and hopefully clarify more about the etiology of the disease.

Outcome Measures
Primary Outcomes (1)
New somatic mutation
Primary outcome measure of this study is to identify new (previously unknown) somatic mutations as a cause for the development of Hirschsprung's disease. Tissue to find these mutations will be gathered during surgery for all patients (see protocol). When sufficient samples are collected (est 25 samples) a first comparative analysis for new somatic mutations will be performed. After the end of the study a final analysis for new somatic mutation will be performed.
During surgery (coolection); after inclusion of approx. 25 patients (preliminairy analysis); final analysis after end of the study (approx. 3 years from first inclusion)
Secondary Outcomes (1)
Correlation disease type
At the end of the study (approximately 3 years after inclusion of first patient)
Eligibility Criteria

You may qualify if:
- All children with Hirschsprung's disease that will receive a corrective pull through procedure
You may not qualify if:
- None
