An appendectomy is surgery to remove the appendix. The appendix is a small, finger-shaped sac extending from the first part of the large intestine. It is removed when it becomes inflamed or infected. An emergency appendectomy will be necessary if there are symptoms of sudden (acute) appendicitis. These symptoms include:

• Abdominal pain (located in the lower right side)

• Fever

• Reduced appetite

• Nausea and vomiting

The pediatric appendectomy inpatient volume measure is reporting on the total number of admissions to a hospital for appendectomy.
