Inguinal Hernia in Children
Overview
A hernia occurs when a part of the intestine or other abdominal
tissue pushes through a weakness in the belly (abdominal) muscles. A soft bulge shows
up
under the skin where the hernia is. A hernia in the groin area is called an inguinal
hernia.
Causes
A hernia can develop in the first few months after a baby is born. It happens because
of a weakness in the abdomen muscles. Straining and crying don’t cause hernias. But
the increased pressure in the belly can make a hernia more easily seen.
As a male baby grows during pregnancy, the testicles develop in the abdomen. Then
they move down into the scrotum through the inguinal canal. Shortly after the baby
is born, the inguinal canal closes. This stops the testicles from moving back into
the abdomen. If this area does not fully close, a part of the intestine can move into
the canal through the weakened area of the lower belly wall. This causes a hernia.
In some cases, the part of intestine that pushes through a hernia may become stuck.
It is no longer reducible. This means it can’t be gently pushed back into the belly.
When this happens, that part of the intestine may not get enough blood. A good blood
supply is needed for the intestine to be healthy and to work the right way.
Girls don’t have testicles. But
they do have an inguinal canal. So they can also have hernias in the groin.
Risk Factors
Hernias happen more often in babies who are born early. They are also more common
in children who have:
- A parent or sibling who had a hernia as an infant
- Cystic fibrosis
- Developmental dysplasia of the hip
- Undescended testes
- Problems with the urethra
Symptoms
Inguinal hernias look like a bulge
or swelling in the groin or scrotum. You may be able to see the swelling more easily
when the baby cries. It may get smaller or go away when the baby relaxes. If your
child’s healthcare provider gently pushes on this bulge when your child is calm and
lying down, it will often get smaller or go back into the belly.
If the hernia can’t be pushed back into the belly, the loop of intestine may be stuck
in the weakened part of abdominal muscle. If that happens, symptoms may include:
- A full, round belly
- Vomiting
- Pain or fussiness
- Redness or a color that's not
normal
- Fever
- Firm and tender bulge
These symptoms may look like other
health problems. Make sure your child sees their healthcare provider for a
diagnosis.
Diagnosis
To diagnose a hernia, your child’s healthcare provider will do a
physical exam. They will check if the hernia can be pushed back into the abdomen
(reducible).
Treatment
Treatment will depend on your
child’s symptoms, age, and general health. It will also depend on how severe the
condition is.
Your child will need surgery for an
inguinal hernia. The surgery will happen fairly soon after the hernia is found. That’s
because the intestine can become stuck in the inguinal canal. When this happens, the
blood supply to the intestine can be cut off. The intestine can then become damaged.
Surgery is often done before this damage can occur.
During surgery for a hernia, your
child will be given medicine to put them to sleep (anesthesia). The surgeon makes
a
small cut (incision) in the area of the hernia. The surgeon puts the loop of intestine
back into the abdominal area. They stitch the muscles together. Sometimes a piece
of
meshed material is used to help strengthen the area where the muscles are fixed.
Complications
Complications of an inguinal hernia include:
- Part of the intestine becoming stuck in the belly muscles
- Lifelong (permanent) damage to the
intestine because of not enough blood flow
Key Points
- A hernia occurs when a part of the
intestine or other abdominal tissue pushes through a weakness in the belly muscles.
When that happens in the groin area, it’s called an inguinal hernia.
- Inguinal hernias often occur in
newborns.
- Babies born early or who have a family
history of hernias are more likely to develop one.
- Inguinal hernias show up as a bulge or
swelling in the groin or scrotum. Sometimes they can be pushed back into the
belly.
- Your child needs surgery to treat an
inguinal hernia.
Next Steps
Tips to help you get the most from a visit to your child’s healthcare provider:
- Know the reason for the visit and what you want to happen.
- Before your visit, write down questions you want answered.
- At the visit, write down the name of a
new diagnosis, and any new medicines, treatments, or tests. Also write down any new
directions your provider gives you for your child.
- Know why a new medicine or treatment
is prescribed and how it will help your child. Also know what the side effects
are.
- Ask if your child’s condition can be treated in other ways.
- Know why a test or procedure is recommended and what the results could mean.
- Know what to expect if your child does not take the medicine or have the test or procedure.
- If your child has a follow-up appointment, write down the date, time, and purpose
for that visit.
- Know how you can contact your child’s
healthcare provider after office hours. This is important if your child becomes ill
and you have questions or need advice.
