Classification
Based on the extent of colon involvement Hirschsprung's disease can be classified into the following:
Rectosigmoid (short) form:
- It is the most common form and is seen in 80 to 75% of infants diagnosed with Hirschsprung's disease.
Long segment colonic Hirschsprung disease:
- also known as total colonic aganglionosis.
- The disease has ileal involvement up to 50 cm proximal to the ileocecal junction.
- It is uncommon and accounts for 5 to 7% of cases diagnosed with Hirschsprung's disease.
Ultra short segment Hirschsprung's disease:
- Only the internal anal sphincter is affected.
- It is also called as internal anal sphincter achalasia.
