What is the appendix? — The appendix is a long, thin pouch shaped like a finger. It hangs down from the large intestine, which is also called the colon (figure 1).
What is appendicitis? — Appendicitis is the term doctors use when the appendix gets infected and swells. When that happens, the appendix can sometimes burst. A burst appendix can be serious, because it can cause a bad infection.
Appendicitis can happen in children and adults. When it happens in children, it is more likely to affect older children and teens than babies or younger children.
What are the symptoms of appendicitis? — Symptoms can be different, depending on a child's age. The most common symptoms are:
●Belly pain – In older children and teens, belly pain is usually the first symptom. The pain might start around the belly button and then move to the right side of the lower belly. Children can also have belly pain that gets worse with coughing or hopping.
●Loss of appetite
●Nausea and vomiting
●Fever – Fever often starts after 1 to 2 days.
Should my child see a doctor? — Yes. Call your child's doctor or nurse if your child has the symptoms listed above.
If your child does have appendicitis, get treatment as soon as possible. The risk of the appendix bursting is much higher after the first 24 hours of symptoms.
Will my child need tests? — Maybe. Your child's doctor or nurse will first ask about the symptoms and do an exam. They might be able to tell if your child has appendicitis without doing any tests.
If the doctor or nurse can't tell for sure if your child has appendicitis, they might do 1 or more of the following tests:
●Blood tests
●Urine tests
●An imaging test such as an ultrasound or CT scan – Imaging tests create pictures of the inside of the body.
No test can say for sure if a child has appendicitis. But the doctor or nurse can use the test results, symptoms, and exam to figure out how likely it is that your child has appendicitis.
How is appendicitis treated? — The main treatment for appendicitis is surgery to remove the appendix. This surgery can be done in 2 ways:
●Open surgery – During open surgery, the doctor makes a cut in the belly near the appendix. Then, they remove the appendix through that opening.
●Laparoscopic surgery – During laparoscopic surgery, the doctor makes a few cuts in the belly that are much smaller than the cuts for open surgery. They put long, thin tools into the belly through these openings. One of the tools has a camera (called a "laparoscope") on the end, which sends pictures to a TV screen. The doctor can look at the image on the screen to know where to cut and what to remove. Then, they use the tools to do the surgery.
If your child's appendix burst, the doctor will do surgery to remove the appendix. During the surgery, they will also clean out the area in the belly around the appendix to wash away the material that spilled out of the burst appendix. This surgery can be more complicated than the surgery that is done if the appendix has not burst.
If it has been more than a few days since your child's appendix burst, the body sometimes forms a wall around the appendix to block off the infection. When this happens, the treatment plan depends on the situation and how sick the child is. Your child's doctor will talk to you about the best approach. After the doctor treats the infection, they will schedule surgery to take out the appendix. Without surgery, there is a higher risk of problems.
Can appendicitis be treated without surgery? — Appendicitis is usually treated with surgery. But in certain cases, if it is found very early and the appendix has not burst, doctors might try treating it with antibiotics in the hospital. This is not an option for all children.
