Appendicitis is a painful swelling and infection of the appendix. It is a medical emergency. The appendix can burst or rupture. This is serious and can lead to more infection. If not treated, it can be fatal.
The appendix is a thin, finger-shaped tube that is joined to the large intestine. It sits in the lower right part of the belly (abdomen). Experts don’t know for sure what role the appendix has in the body. It is not a vital organ. Removing it is not harmful.
Surgery to remove the appendix is called an appendectomy. It is the most common type of emergency surgery for children. Most children recover with no long-term problems.
Appendicitis happens when the inside of the appendix is blocked by something, causing an infection. The blockage may be caused by nose or mouth fluid, called mucus. It can also occur because of stool or parasites. Or the blockage may be caused by a bend or twist in the appendix itself.
The appendix then becomes sore and inflamed or swollen. This is because the germs (bacteria) in the appendix begin to increase quickly. As the swelling and soreness get worse, the blood supply to the appendix is cut off.
All parts of the body need the right amount of blood flow to stay healthy. When blood flow is reduced, the appendix starts to die. The appendix will burst or rupture as its walls start to get holes. These holes let stool, mucus, and other substances leak through and get inside the belly or abdomen. A serious infection called peritonitis may occur in the belly when the appendix bursts. If not treated, it can be fatal.
Each child’s symptoms may vary. Below are some common symptoms of appendicitis.
Pain in the belly (abdomen) is the most common symptom. This pain:
Other common symptoms include:
Your child’s healthcare provider will take a health history and do a physical exam. The provider may also order tests, including:

Symptoms of appendicitis may look like other health problems. Always see your child’s healthcare provider for a diagnosis.
Treatment will depend on your child’s symptoms, age, and general health. Appendicitis is a medical emergency. It is likely the appendix will burst and cause a serious, deadly infection. For this reason, your child’s healthcare provider will likely advise that your child have surgery to remove the appendix.
The appendix may be removed in two ways:
Sometimes the appendix bursts, and a collection of infected fluid or pus (abscess) may form. If this happens and your child is stable, the provider may recommend not removing the appendix right away. Instead, the provider may want to treat the infection first and drain the infected fluid from the abscess. The appendix will be removed later. This delayed surgery is called an interval appendectomy.
For an interval appendectomy, your child may first have IV antibiotics. These are given through an IV tube called a PICC line, or a peripherally inserted central catheter. This is done for about 10 to 14 days. In addition, the provider may use CT or ultrasound-guided images to drain the abscess. Once the infection and inflammation are gone, your child will have surgery to remove the appendix about 6 to 8 weeks later.
A child whose appendix ruptured will have to stay in the hospital longer than a child whose appendix was removed before it burst. Some children will need to take antibiotics by mouth for a certain period of time after they go home.
After surgery, your child will not be allowed to eat or drink anything for a certain period of time. This lets the intestine heal. During this time, fluids will be given by IV into the bloodstream. Your child will also have antibiotics and medicines to ease pain through the IV.
At some point, your child will be able to drink clear liquids such as water, sports drinks, or apple juice. He or she will slowly move on to solid foods.
After your child leaves the hospital, the healthcare provider will likely limit his or her activities. Your child should not do any heavy lifting or play contact sports for a few weeks after surgery. If a drain is still in place when your child goes home, he or she should not take a bath or go swimming until the drain is removed.
You will be given a prescription for pain medicine for your child to take at home. Some pain medicines can make a child constipated, so ask your healthcare provider or pharmacist about any side effects. Moving around after surgery rather than lying in bed can help prevent constipation. Drinking fruit juices may also help. Once your child can have solid foods again, eating fruits, whole grain cereals and breads, and vegetables can also help stop constipation.
Most children who have their appendix removed will have no long-term problems.
