Pediatric Appendicitis

Pediatric Appendicitis



Appendicitis means the appendix is infected and inflamed. Acute appendicitis can cause abdominal pain and is a leading cause of emergency pediatric abdominal surgery.

Expanded Overview

Annually, 70,000 cases of pediatric appendicitis occur in the U.S. It occurs most often in children between the ages of 10 and 17.

The rates of appendicitis are higher in developed nations, correlating to diets that are low in fiber and high in sugar. Other risk factors include family history and infection.

The inflammation and infection of the appendix triggers obstructions of drainage and blood flow, so trapped bacteria multiply, distending the appendix and leading to ischemia. Without intervention, necrosis and gangrene occur; a perforated appendix could occur within 72 hours after the original obstruction.

When that happens, bacterial-laden inflammatory fluid leaks into the abdominal cavity, potentially resulting in peritonitis – a serious condition.


  • Abdominal pain
  • Fever
  • Vomiting

Symptoms might not show up in children. Delayed diagnosis increases the risk of rupture and its serious complications.


Conservative approach

Not every case of perforated appendicitis needs an emergency appendectomy; in some cases, medical management of the infection allows for an appendectomy to be postponed.

In that case, patients are started on IV fluids, in place of regular diet, and receive intravenous antibiotic therapy. Patients who fail to improve on medical management will require surgical treatment fairly quickly.


Acute appendicitis requires an appendectomy. Laparoscopic surgery is most often used. Surgeons can drain any abscesses encountered during surgery. Rarely, severe inflammation requires preliminary drainage and dealing with other symptoms before the appendix is removed.
