Anal endosonography in children with chronic constipation

Area of Science:

• Pediatric Gastroenterology
• Anorectal Physiology
• Diagnostic Imaging

Background:

• Internal anal sphincter (IAS) hypertrophy is observed in some children.
• The clinical significance of IAS hypertrophy in pediatric chronic constipation remains undetermined.

Purpose of the Study:

• To evaluate anal endosonographic findings in children diagnosed with chronic constipation.
• To compare endosonographic measurements with established normal values for pediatric anal sphincters.

Main Methods:

• Anal endosonography was performed on a cohort of 46 children with chronic constipation.
• Sphincter thickness was measured and compared to normal reference ranges.
• Correlation with age and clinical response to medical management was assessed.

Main Results:

• No significant relationship was identified between patient age and the thickness of either the internal or external anal sphincters.
• The clinical outcomes of medical management did not vary between children with and without evidence of sphincter hypertrophy.

Conclusions:

• The study found no significant correlation between anal sphincter hypertrophy and the presence of constipation or patient age in the pediatric cohort.
• Further investigation is warranted to elucidate the role of anal sphincter hypertrophy in anorectal pathology and its diagnostic utility.
