[appendix + -itis]
Inflammation of the vermiform appendix, caused by blockage of the lumen of the appendix followed by infection. It may be acute, subacute, or chronic and occasionally is difficult to diagnose because many other illnesses may cause acute abdominal pain.

TREATMENT
Surgery is typically required. Preoperative intravenous hydration and antibiotics are given in most instances.
