10792 Appendicitis In Children

Overview

Appendicitis is swelling and infection of the appendix, a small tube-shaped pouch attached to the large intestine. If it is not treated quickly, the appendix can burst, which can be very dangerous. In children, appendicitis is a medical emergency that usually requires surgery to remove the appendix.

Appendicitis is fairly common, affecting about 1 in every 1000 children each year. It is one of the most common reasons for emergency abdominal surgery in children.

Appendicitis can happen at any age, but it is most common in children and young people between 10 and 20 years old. It is slightly more common in boys than in girls.

Symptoms

Common symptoms

• Pain that starts near the belly button and moves to the lower right side of the belly
• Pain that gets worse over time, often over 12 to 24 hours
• Loss of appetite
• Nausea or vomiting
• Swollen belly
• Fever, usually not very high at first

Symptoms in children

• Young children may not be able to describe the pain clearly and may just cry or hold their belly.
• They may complain that walking, jumping, or being bumped hurts the belly.
• They may have a low fever and vomit.
• Your child may refuse to eat and may seem unusually tired or irritable.

Symptoms in older adults

• Older adults with appendicitis may have milder pain and a lower fever, which can delay diagnosis.
• They may not have the classic lower right belly pain, so the condition can be harder to spot.

Causes

Main causes

• The appendix becomes blocked, often by a small piece of stool, a swollen lymph node, or an infection.
• Blockage causes the appendix to swell, which can stop blood flow and allow bacteria to grow.
• If the swelling continues, the appendix can burst and spread infection inside the belly.

Risk factors

• Age: most common in older children and teenagers
• Family history: appendicitis may run in some families
• Digestive conditions: conditions that cause inflammation in the gut may increase risk

When to see a doctor

See a doctor urgently if:

• See a doctor the same day if your child has belly pain that is getting worse, lasts more than a few hours, or moves to the lower right side.
• Call your local health service or take your child to urgent care if they have belly pain with vomiting, fever, or loss of appetite.

Book a routine appointment if:

• If your child has mild belly pain that comes and goes and no other symptoms, you can usually wait a few hours and monitor. But if it persists, see a doctor.

Diagnosis

A doctor will ask about your child's symptoms and examine their belly by gently pressing on different areas. The doctor will also ask about pain with movement and other signs.

Tests that may be done

• Blood tests to check for signs of infection or inflammation
• Urine test to rule out a urine infection
• Imaging tests, such as an ultrasound or sometimes a CT scan, to look at the appendix

What to expect at your appointment

Your child may need to stay in the hospital for observations and tests. If the doctor is not sure about the diagnosis, they may wait a few hours and re-examine your child. This is normal and helps avoid unnecessary surgery.

Treatment

The standard treatment for appendicitis in children is surgery to remove the appendix, called an appendicectomy or appendectomy. This is usually done quickly to prevent the appendix from bursting. In some mild cases, antibiotics alone may be used, but surgery remains the most reliable treatment.

Self-care at home

• Do not give your child any painkillers before seeing a doctor, as they can mask symptoms.
• Do not give your child anything to eat or drink if surgery is likely, as they may need an empty stomach.
• If your child is at home and being observed, follow the doctor's advice on what to do.

Medical treatments

Treatment always starts with a full medical assessment. If appendicitis is confirmed, your child will usually have surgery to remove the appendix. This can be done as keyhole surgery (laparoscopy) or through a small cut in the lower belly. Your child will also receive fluids through a drip and antibiotics through a vein before and after surgery to fight infection. You will be given specific instructions on how to care for the wound and when your child can return to normal activities.

When is surgery considered?

Surgery is the standard treatment for appendicitis in children. If the appendix has already burst, surgery is still needed to clean the belly and remove the appendix. Some children with a small, well-contained infection may be treated with antibiotics first and surgery later, but this depends on the child's situation.

Living with this condition

After surgery, most children feel much better within a few days. They may need to stay in the hospital for 1 to 3 days, or longer if the appendix had burst. The surgical wound should be kept clean and dry. Your child can gently move around but should avoid heavy lifting, sports, or rough play for a few weeks.

Lifestyle tips

• Encourage your child to rest and take it easy for the first week at home.
• Keep follow-up appointments with the doctor or surgeon.
• Watch for signs of infection, such as redness, swelling, or discharge from the wound.
• Encourage a healthy diet and plenty of fluids to help recovery.

Diet and exercise

Your child can usually start with clear fluids, then soft foods, and return to a normal diet as tolerated. After surgery, it is important to avoid intense physical activities for about 2 to 4 weeks, but walking and light play are fine. Always follow the surgeon's advice on when it is safe to go back to school and sports.

Mental health and emotional wellbeing

Having surgery can be scary for a child. They may feel anxious, sad, or frustrated about missing school and activities. Talk to your child openly, reassure them that the pain will go away, and let them know it is okay to feel upset. Offer comfort and calm distractions like books, games, or movies.

Prevention

There is no proven way to prevent appendicitis. It usually happens without warning. The best thing you can do is recognize the symptoms early and seek medical help quickly, which prevents the worst complications.

Vaccines

There is no vaccine to prevent appendicitis.

Screening programmes

There is no routine screening test for appendicitis in children.

Complications

If left untreated

• The appendix can burst, causing infection to spread inside the belly (peritonitis).
• A collection of pus (abscess) may form around the appendix.
• A burst appendix can lead to a longer hospital stay, more pain, and a more complicated recovery.
• In rare cases, the infection can spread into the bloodstream, which can be life-threatening.

Long-term outlook

With prompt medical care, the outlook for children with appendicitis is excellent. Most children recover fully with no long-term problems. They can live a completely normal and healthy life without their appendix. The surgery is safe, and most children are back to their usual routines within a few weeks.
