Final answer:
If the appendix ruptures, the life-threatening condition that develops is peritonitis. It is the inflammation of the peritoneum caused by the spillage of gastrointestinal contents due to a ruptured appendix, and it necessitates emergency medical treatment.
Step-by-step explanation:
If the appendix ruptures, the resulting medical condition that quickly becomes life-threatening is peritonitis. Appendicitis is the inflammation of the appendix, which if left untreated can lead to perforation or rupture. This rupture allows the contents of the gastrointestinal tract, including bacteria, to spill into the abdominal cavity and cause peritonitis. Peritonitis is inflammation of the peritoneum, the lining of the abdominal cavity. This is a serious condition that often requires emergency surgery to remove the infected material and intensive antibiotic therapy to tackle the infection.
Bacterial infections that lead to conditions like appendicitis and colonic diverticulitis are some of the causes of peritonitis. Historically, peritonitis had a high mortality rate, but advancements in medical treatments have improved survival rates. Nonetheless, mortality still ranges from 30 to 40 percent, making immediate medical attention crucial.
