Appendicitis
From Wikipedia, the free encyclopedia |
Appendicitis is a medical emergency characterized by inflammation of the appendix, many cases of which require removal of the inflamed appendix, either by laparotomy or laparoscopy. Untreated, mortality is high, mainly because of the risk of rupture leading to infection and inflammation of the intestinal lining (peritoneum) and eventual sepsis, clinically known as peritonitis which can lead to circulatory shock. Reginald Fitz first described acute and chronic appendicitis in 1886, and it has been recognized as one of the most common causes of severe acute abdominal pain worldwide. A correctly diagnosed non-acute form of appendicitis is known as "rumbling appendicitis". Appendicitis is most common between the ages of 5 and 40; the median age is 28. It tends to affect males, those in lower income groups, and, for unknown reasons, people living in rural areas.
The term "pseudoappendicitis" is used to describe a condition mimicking appendicitis. It can be associated with Yersinia enterocolitica. acute appendicitis appendicitis of acute onset, requiring prompt surgery, and usually marked by pain in the right lower abdominal quadrant, referred rebound tenderness, overlying muscle spasm, and cutaneous hyperesthesia. chronic appendicitis
1. that characterized by fibrotic thickening of the organ wall due to previous acute inflammation.
2. formerly, chronic or recurrent pain in the appendiceal area, without evidence of acute inflammation. fulminating appendicitis that marked by sudden onset and usually death. gangrenous appendicitis that complicated by gangrene of the organ, due to interference of blood supply. obstructive appendicitis a common form with obstruction of the lumen, usually by a fecalith.
