If your child has functional constipation and is not responding well to a bowel management program, pediatric colorectal specialists and gastroenterologists will perform a series of diagnostic tests to determine the underlying cause of the condition. 

If your child is a candidate for surgery, the type of surgery your child will need and when to perform it is based on a comprehensive evaluation of the anorectal and colorectal anatomy and physiology.

The following diagnostic tests and tools are performed to diagnose the causes of functional constipation:


Contrast Enema

Sitz Marker Study

Colonic Nuclear Transit Study (Colonic Transit Scintigraphy)

Colonic Manometric Tests

SmartPill™ Motility System (Medtronic)

Anorectal Manometry
