Summary
Anorectal manometry effectively assesses anorectal function in children, particularly for constipation and malformations. This study highlights its utility in diagnosing conditions like Hirschsprung disease.
Area of Science:
- Pediatric Gastroenterology
- Diagnostic Procedures
Background:
- Anorectal manometry is a valuable, non-invasive tool for evaluating anorectal function.
- Its application in pediatric populations requires further analysis of diagnostic yield and specific conditions.
Purpose of the Study:
- To review anorectal manometry studies performed in children over five years.
- To evaluate the diagnostic accuracy and findings in various anorectal disorders, including constipation and malformations.
Main Methods:
- Retrospective review of 234 anorectal manometry procedures in patients aged 21 years or younger.
- Analysis of indications, completion rates, and manometric findings, including internal and external anal sphincter pressures.
Main Results:
- Constipation was the primary indication (78.20%).
- Patients with anorectal malformations showed statistically lower internal anal sphincter pressure and a higher rate of inconclusive studies compared to constipated patients.
- Manometry suggested Hirschsprung disease in 43 patients, with 91.66% confirmed by histology.
Conclusions:
- Anorectal manometry is a useful tool for assessing anal sphincter integrity, especially in pediatric anorectal malformations.
- The study supports its role in the diagnostic workup of complex pediatric anorectal conditions, including suspected Hirschsprung disease.
