Symptoms and Sign of Appendicitis

appendicitis
appendicitis symptoms Approximately 7% of people in Western countries have appendicitis at some time during their lives, and about 200,000 appendectomies for acute appendicitis are performed annually in the United States. The incidence has been steadily dropping over the past 25 years, however, while the incidence in developing countries—which in the past has been quite low—has been rising in proportion to economic gains and changes in lifestyle.

Obstruction of the proximal lumen by fibrous bands, lymphoid hyperplasia, fecaliths, calculi, or parasites has long been considered to be the major cause of acute appendicitis, though that theory is doubted by many experts. Evidence of temporal and geographic clustering of cases has suggested a primary infectious etiology. A fecalith or calculus is found in only 10% of acutely inflamed appendices.

As appendicitis symptoms progresses, the blood supply is impaired by bacterial infection in the wall and distention of the lumen by pus; gangrene and perforation occur at about 24 hours, though the timing is highly variable. Gangrene implies microscopic perforation and bacterial peritonitis (which may be localized by adhesions from nearby viscera).We will review sign of appendicitis soon. sign of appendicitis
