Encopresis

Definition

If a child over 4 years of age has been toilet trained, and still passes stool and soils clothes, it is called encopresis. The child may or may not be doing this on purpose.

Alternative Names

Soiling; Incontinence - stool; Constipation - encopresis; Impaction - encopresis

Causes

The child may have constipation. The stool is hard, dry, and stuck in the colon (called fecal impaction). The child then passes only wet or almost liquid stool that flows around the hard stool. It may leak out during the day or night.

Other causes may include:

Not toilet training the child
Starting toilet training when the child was too young
Emotional problems, such as oppositional defiant disorder or conduct disorder

Whatever the cause, the child may feel shame, guilt, or low self-esteem, and may hide signs of encopresis.

Factors that may increase the risk of encopresis include:

Chronic constipation
Low socioeconomic status

Encopresis is much more common in boys than in girls. It tends to go away as the child gets older.

Symptoms

Symptoms can include any of the following:

Being unable to hold stool before getting to a toilet (bowel incontinence)
Passing stool in inappropriate places (as in the child's clothes)
Keeping bowel movements a secret
Having constipation and hard stools
Passing a very large stool sometimes that may block the toilet
Loss of appetite
Urine retention
Refusal to sit on the toilet
Refusal to take medicines
Bloating sensation or pain in the abdomen

Exams and Tests

Your health care provider may feel the stool stuck in the child's rectum (fecal impaction). An x-ray of the child's belly may show impacted stool in the colon.

Your provider may perform an exam of the nervous system to check for a spinal cord problem.

Other tests may include:

Treatment

The goal of treatment is to:

Prevent constipation
Keep good bowel habits

It is best for parents to support, rather than criticize or discourage the child.

Treatments may include any of the following:

Giving the child laxatives or enemas to remove dry, hard stool.
Giving the child stool softeners, such as magnesium hydroxide, lactulose, or polyethylene glycol powder, as recommended by your provider.
Having the child eat a diet high in fiber (fruits, vegetables, whole grains) and drink plenty of fluids to keep the stools soft and comfortable.
Taking flavored mineral oil for a short period of time. This is only a short-term treatment because mineral oil interferes with the absorption of calcium and vitamin D.
Seeing a pediatric gastroenterologist when these treatments are not enough. Your gastroenterologist may use biofeedback, or teach the parents and child how to manage encopresis.
Seeing a psychotherapist to help the child deal with associated shame, guilt, or loss of self-esteem.

For encopresis without constipation, the child may need a psychiatric evaluation to find the cause.

Outlook (Prognosis)

Most children respond well to treatment. Encopresis often recurs, so some children need ongoing treatment.

Possible Complications

If not treated, the child may have low self-esteem and problems making and keeping friends. Other complications may include:

Chronic constipation
Urinary incontinence

When to Contact a Medical Professional

Contact your provider for an appointment if a child is over 4 years old and has encopresis.

Prevention

Encopresis can be prevented by:

Toilet training your child at the right age and in a positive way.
Talking to your provider about things you can do to help your child if your child shows signs of constipation, such as dry, hard, or infrequent stools.
