Evaluates imaging techniques and biopsy for Hirschsprung disease diagnosis in neonates, suggesting reliable confirmatory methods.
Contrast enema is the primary modality for diagnosing Hirschsprung’s disease in the neonate. The most common findings on imaging are a rectosigmoid transitional zone, an abnormal rectosigmoid index, and a saw-tooth pattern depicting impaired peristalsis. The absence of a transitional zone in the neonate may observed due to immature bowel. A suction rectal biopsy is the gold standard to confirm the diagnosis.
