Definition:

A bezoar is a ball of swallowed foreign material (usually hair or fiber) that collects in the stomach and fails to pass through the intestines.



Alternative Names:

Trichobezoar; Hairball



Causes, incidence, and risk factors:

Chewing on or eating hair or fuzzy materials (or indigestible materials such as plastic bags) can lead to the formation of a bezoar. The rate is very low and the risk is greater among mentally retarded or emotionally disturbed children. Generally bezoars are mostly seen in females aged 10 to 19.



Symptoms:

Signs and tests:

The child may have a lump in the abdomen that can be felt by the health care provider. A barium swallow x-ray will show the mass in the stomach, sometimes a scope is used (endoscopy) to directly view the bezoar.



Treatment:

The bezoar may need to be surgically removed (especially trichobezoars which tend to be large). Sometimes small bezoars can be removed through a scope placed through the mouth and into the stomach (similar to an EGD procedure). Then, follow the prevention measures described.



Support Groups:



Expectations (prognosis):

Full recovery is expected.



Complications:

Persistent vomiting can lead to dehydration .



Calling your health care provider:

Call your health care provider if you suspect your child has a bezoar.



Prevention:

If your child has had a hair bezoar in the past, trim the child's hair short so he or she cannot put the ends in the mouth. Keep indigestible materials away from a child that has a tendency to put items in the mouth.

Be sure to remove the child's access to fuzzy or fiber-filled materials.
