Ano-rectal manometry in the diagnosis of Hirschsprung's disease in infants
Insights
Ano-rectal manometry effectively diagnoses Hirschsprung's disease in infants by assessing internal sphincter response to rectal distension. This non-invasive method shows high accuracy in identifying the condition, aiding early intervention.
Area of Science:
- Pediatric Gastroenterology
- Surgical Diagnostics
- Infant Physiology
Background:
- Hirschsprung's disease is a congenital disorder characterized by the absence of ganglion cells in the distal bowel.
- Accurate and early diagnosis is crucial for effective management and to prevent complications.
- Current diagnostic methods may have limitations in infants.
Purpose of the Study:
- To evaluate the efficacy of ano-rectal manometry in diagnosing Hirschsprung's disease in infants.
- To assess the internal sphincter's response to rectal distension as a diagnostic marker.
- To determine the safety and reliability of ano-rectal manometry in this pediatric population.
Main Methods:
- Manometric recordings of internal sphincter activity during rectal distension were performed.
- 10 healthy infants and 9 infants with suspected Hirschsprung's disease were studied.
- Results were correlated with subsequent rectal biopsy findings.
Main Results:
- Healthy infants and those without Hirschsprung's disease typically exhibited internal sphincter relaxation post-distension.
- Infants diagnosed with Hirschsprung's disease showed an absence of this relaxation.
- The procedure was found to be easy, safe, and well-tolerated by the infants.
Conclusions:
- Ano-rectal manometry is a valuable, accurate, and non-invasive tool for diagnosing Hirschsprung's disease in infants.
- The study reported no false results, highlighting its diagnostic reliability.
- This method offers a low-risk alternative or adjunct to traditional diagnostic procedures.
Abstract:
Manometric recordings of internal sphincter activity were performed during distension of the rectum in 10 healthy control infants and in 9 infants with clinical signs of Hirschsprung's disease. In 8 of the healthy infants relaxations of the internal sphincter were obtained, which were maximal 4 to 7 secs after rectal distension. This was also the case in 5 of the patients who were later proven not to have Hirschsprung's disease. In 3 patients no relaxations of the internal sphincter could be recorded. Subsequent rectal biopsy revealed absence of ganglion cells, confirming the diagnosis Hirschsprung's disease. The remaining 3 infants (2 controls and 1 patient) could not be calmed during the examination and the results were inconclusive. It is concluded that ano-rectal manometry is a valuable method of examination in the diagnosis of Hirschsprung's disease in infants. No false results were obtained in this study. Furthermore, it is an easy procedure without risk or discomfort for the patient.
