Study Notes
Hirschsprung Disease
- The male-female ratio in Hirschsprung Disease cases is approximately 4:1, indicating a higher prevalence in males.
- In about 80% of cases, the disease is limited to the rectosigmoid, which is the lowest part of the large intestine.
- Hirschsprung Disease is characterized by the congenital absence of parasympathetic innervation of the distal intestine, also known as aganglionosis.
- The estimated occurrence of Hirschsprung Disease in live births is about 1 in 5,000.
- The etiology of Hirschsprung Disease is attributed to a combination of genetic and environmental factors, which lead to the failure of neural crest cells to migrate to the distal intestine during fetal development.
