 The end result is appendiceal rupture (a 'burst appendix') causing peritonitis, which may lead to sepsis and eventually death.These events are responsible for the slowly evolving abdominal pain and other commonly associated symptoms.The causative agents include bezoars, foreign bodies, trauma, intestinal worms, lymphadenitis and, most commonly, calcified fecal deposits that are known as appendicoliths or fecaliths.
