Diagnostic Tests in Pediatric Constipation

Area of Science:

• Pediatric Gastroenterology
• Gastrointestinal Motility Disorders

Background:

• Constipation is a common pediatric gastrointestinal symptom, with a 12% prevalence.
• It accounts for 25% of pediatric gastroenterology consultations.
• Most childhood constipation is functional and doesn't require extensive testing.

Purpose of the Study:

• To review diagnostic investigations for severely constipated children.
• To analyze the indications and clinical utility of these assessments.
• To discuss advancements in understanding pediatric colonic and anorectal motility.

Main Methods:

• Narrative review of diagnostic investigations.
• Discussion of techniques for measuring colonic and anorectal motility.
• Analysis of instrumental assessments for evaluating pathophysiologic mechanisms and organic etiologies.

Main Results:

• The review covers various diagnostic tools for severe pediatric constipation.
• It highlights the increased knowledge of pediatric motility over the last decade.
• Different techniques for transit and motility measurement are presented.

Conclusions:

• Instrumental assessment is crucial for children unresponsive to conventional treatment or with significant clinical signs.
• Accurate evaluation helps determine underlying pathophysiologic mechanisms or organic causes.
• Understanding motility is key to managing severe pediatric constipation.
