Hirschsprung's disease complicating colon atresia

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Neonatal Medicine

Background:

• Colon atresia and Hirschsprung's disease are rare congenital gastrointestinal anomalies.
• Congenital cardiac defects, such as tetralogy of Fallot, can occur alongside gastrointestinal malformations.

Observation:

• A rare case of an infant presenting with a combination of colon atresia, total colonic Hirschsprung's disease, and tetralogy of Fallot is described.
• Initial surgical interventions for colon atresia were unsuccessful due to the coexisting, unrecognized aganglionosis characteristic of Hirschsprung's disease.
• Histological examinations of resected colon initially showed normal results, with the absence of ganglion cells only appreciated upon review prompted by clinical deterioration.

Findings:

• This is the first reported case of Hirschsprung's disease associated with both colon atresia and congenital cardiac disease.
• Functional obstruction persisted after initial surgeries due to the misdiagnosis of aganglionosis.

Implications:

• Highlights the critical importance of suspecting coexisting Hirschsprung's disease in infants with colon atresia presenting with functional obstruction.
• Underscores the need for careful histological review and clinical correlation to ensure accurate diagnosis and appropriate management of complex neonatal surgical conditions.
• Suggests a potential link or shared etiology between these rare congenital anomalies, warranting further investigation.
