Encopresis / Paradoxical Diarrhea

What is Encopresis?

Encopresis also referred to as paradoxical diarrhea or fecal soiling refers to the mostly involuntary leakage of stool leading to soiling of clothes. It is usually seen in children who have been toilet trained (above 4 years) but can occur in adults also. The causative factors in children and adults may vary.

In children the most common cause is constipation which typically happens before encopresis. Due to constipation, the accumulated feces becomes hard and remains in the rectum. When the rectum becomes distended and full, liquid stool leaks around the hard impacted feces and stains the clothes.

How do you Diagnose Encopresis?

Parents may seek medical advice due to problems with child’s bowel habits and episodes of fecal soiling.

History and physical examination

The doctor will obtain a detailed history including occurrence of constipation, diet history, details of toilet training and conduct a thorough physical examination to identify cause of constipation and rule out other causes of fecal soiling

Digital rectal examination

The doctor gently introduces a lubricated, gloved finger into the anal opening while gently pressing the lower part of the belly with the other hand and checks for presence of hard impacted fecal mass

Imaging

• Abdominal x-ray to check the amount of stool in the large intestine and demonstrate hard fecal mass
• Contrast enema, a test that gives a clearer picture of the bowel to check for blockage of intestine, any abnormal narrowing or other conditions that may be causing constipation

Psychological evaluation

If the doctor suspects emotional disturbances as the possible cause of fecal soiling, he may recommend a psychological evaluation

How do you Treat Encopresis?

Treating Encopresis in a Child

The earlier treatment begins for encopresis, the better for the child. It is important during evaluation to distinguish whether encopresis in a child is due to constipation or occurs in the absence of constipation because each requires a different treatment.

In encopresis with constipation, laxatives combined with toilet training is the method of treatment. In the absence of constipation, the main form of treatment is toilet training

• Clearing the colon of retained, impacted stool
• Toilet Training
• Lifestyle changes to ensure regular bowel movement
• Psychotherapy

Clearing the Colon

The colon must first be cleared of the impacted feces. This can be done by using

• Laxatives – These are orally administered agents that act by stimulating bowel movement, reducing transit time of digested food in the bowel and softening the stool eg castor oil, senna, milk of magnesia, magnesium sulphate, psyllium
• Enema – A tube is introduced into the rectum to infuse fluid that will stimulate evacuation of bowel. Usually enemas contain a mixture of soap and water or glycerine and water and are used to relieve constipation

Toilet Training

Children should be made to sit on the toilet three times a day, after meals. This is particularly useful since the bowel movement is stimulated when food enters the stomach.

Lifestyle Changes to Avoid Constipation

• Encourage the child to take plenty of fluids
• Consume fiber rich diet - apples, strawberries, dark green leafy vegetables, beans, broccoli
• Consume dairy products as per doctor’s advice
• Training the child to empty bowels as soon as the urge to pass stools is felt
• Placing a foot stool in the toilet can help the child to change the position of the legs to put more pressure on the belly and ease bowel movement
• Laxatives if needed and discontinuing once a regular bowel pattern sets in
• Encouraging activity and play by limiting TV time or smartphone use

Psychotherapy

• Counseling to retrain bowel and cause behavior modification
• Biofeedback
• Be gentle with the child and do not criticize for soiling clothes
• Praise the child for following prescribed diet, going to the toilet and be supportive
• Sometimes when encopresis happens in the absence of constipation psychologic evaluation may be considered to find a possible cause

Encopresis in Adults

A more careful assessment has to be done as there are many underlying conditions that can cause chronic constipation. Finding the cause and treating it is important.

However, initial treatment must include clearing the bowel by prescribing laxatives or giving an enema.

Other measures once the bowel is cleared include lifestyle changes similar to mentioned above and periodic use of stool softeners and fiber supplements to ease bowel movement.
