Causes and Risks of the Infection Appendicitis occurs when bowel contents that flow into the appendix are blocked and cannot flow out. Normal intestinal bacteria get trapped and multiply, causing swelling and infection. The blockage may be due to very thick bowel contents or another obstruction. While cancer of the appendix is very rare, the block is occasionally due to a benign tumor called a carcinoid.Treatment & Prevention of Appendicitis
- Surgery to remove the appendix is called an appendectomy.
- Some people need antibiotics too, to help avoid or cure infection.
- A ruptured appendix may require more extensive surgery. As many as one in five people with this condition end up with a second abdominal abscess (collection of pus).
