Fecal incontinence in children is defined as involuntary defecation at inappropriate times, occurring after the typical age of completed toilet training (generally 4 years of age or older).

In most cases, caused by overflow soiling associated with chronic constipation and severe fecal impaction in an otherwise healthy child without underlying anatomical abnormalities.

May have a significant negative impact on the quality of life for the child and the family.

A thorough history and physical examination are the crux of diagnosis. Laboratory and radiological studies may be used on a case-by-case basis to determine the underlying etiology.

The goal of therapy is for patients to pass stool 1 to 3 times per day in the toilet with no episodes of soiling.

Treatment involves complete colon disimpaction, long-term treatment with laxatives and stool softeners, and bowel re-education. Any underlying causes should also be addressed.

Definition

Fecal incontinence in children is the involuntary passage of stool from the rectum through the anus resulting in episodes of stooling at inappropriate times, occurring at an age after which toilet training is typically complete (in most, 4 years of age or older).
