What is an inguinoscrotal swelling?

What are pediatric hernias?

The protrusion of intra-abdominal contents through any defect in the abdominal wall is known as a hernia. In children of both sexes the most common site of hernia is the groin. The other sites being umbilical, paraumbilical, epigastric and lumbar. During the fetal life there is a normal protrusion of the lining of the abdomen through the deep ring in the groin, known as the processus vaginalis. This opening should normally close after birth. In some children this remains open and manifests as a groin hernia.

What is a pediatric hydrocele?

It is a condition when there is a collection of fluid around the testis of the child. The testis appears much bigger than the other side. This is usually due to a tiny opening in the deep ring though which only fluid can come down. At times the testis might be normal but there might be a fluid filled swelling in the groin. This is called an encysted hydrocele of the cord.

What are the problems that are caused for my child due to hernias or hydroceles?

Hernias and hydroceles are usually painless swellings that do not cause any form of discomfort for the child. At times however in hernias the contents might get stuck at the neck. This is known as an incarcerated hernia. Incarcerated hernias can lead to intestinal obstruction, loss of blood flow to the trapped organ and gangrene of the trapped organ. This is an emergency and needs to be managed immediately.
Hydroceles are relatively benign and may be observed till the child is older. They however do increase the chances of injury to the area especially in a toddler. It is very important to differentiate a hydrocele from an hernia.

How are pediatric hernias and hydroceles treated?

As explained above the cause of hernias and hydroceles is the failure of closure of the deep ring. Therefore medications are not needed for the treatment of the same. A small surgery is done by putting a small cut on the deep ring and tying of the patent processus vaginalis. It is a day care procedure which means that the child is admitted on the day of the surgery and is discharged home on the same day.
The child does complain of a little pain in the operated area that is managed with pain killers. The child is sent home with a waterproof dressing that is removed by the doctor later during the follow up visit. No special care of the child is needed after this procedure.

Can the surgery be done laparoscopically?

In case of hydrocele one may wait till the child is 2 years old or later. In case of other hernias the decision is based on the child and the specific type of the hernia.

What are the long term implications of the hernia surgery for my child?
