[Anorectal manometry in children with chronic functional constipation and encopresis]

Area of Science:

• Pediatric Gastroenterology
• Colorectal Physiology

Background:

• Encopresis and chronic functional constipation are common pediatric conditions.
• Rectal motility studies assess the neuromuscular function of the rectum.

Purpose of the Study:

• To compare rectal motility patterns in children with encopresis versus chronic functional constipation.
• To identify potential physiological differences contributing to encopresis.

Main Methods:

• A rectal motility study using a three-balloon Schuster technique was conducted.
• Pressure changes within the rectum were recorded in pediatric patients.
• The presence or absence of the
• inflation
• reflex was specifically assessed.

Main Results:

• The
• inflation
• reflex was absent in 59% of children with encopresis (23/39).
• In contrast, the reflex was absent in 26.8% of children with chronic functional constipation (11/41).
• This difference was statistically significant (p < 0.05).

Conclusions:

• An absent
• inflation
• reflex is a more frequent finding in children with encopresis.
• This suggests a potential physiological basis for encopresis distinct from chronic constipation.
