Rupture
A rupture is when the appendix bursts or tears. Infants, young children, and older adults are at highest risk of a rupture. If appendicitis is not diagnosed quickly and goes untreated, this particular complication will most likely occur.
Peritonitis or Abscess
Peritonitis is a dangerous infection. This complication can occur when bacteria and other contents of the torn appendix leak into the abdomen (stomach). A ruptured appendix can lead to peritonitis and abscess. An abscess usually takes the form of a swollen mass filled with fluid and bacteria.
