Appendicitis is inflammation of the vermiform appendix caused by an obstruction attributable to infection, structure, fecal mass, foreign body, or tumor. Appendicitis can affect either gender at any age, but is most common in males 10 to 30. Appendicitis is the most common disease requiring surgery. If left untreated, appendicitis may progress to abscess, perforation, subsequent peritonitis, and death.
