An appendicular abscess (abscess in the appendix) is a complication of acute appendicitis – invasion of the appendix of the large intestine by bacteria usually due to an obstruction. The appendix exists at the junction of the small and large intestine and is exposed to the movement of digested food, waste matter and is teeming with bacteria. It is therefore prone to becoming blocked and coupled with an infection, acute appendicitis can even be life threatening. An abscess is not the only possible complication. Other complications include gangrene, appendicular masses, rupture and general peritoneal infections. These complications associated with appendicitis is more likely to occur in a patient who delays in seeking medical attention.
What is an appendicular abscess?
An appendicular abscess is a collection of pus resulting from perforation or rupture of acutely inflamed appendix. The pus remains localized close to the appendix, because it is walled off by adhesions formed by the surrounding abdominal structures. This prevents the pus from leaking and the infection spreading throughout the peritoneal cavity.
