[Trends in the incidence of acute appendicitis in Italy during the past 30 years]

Abstract

The incidence and mortality rate of acute appendicitis for the years 1955 and 1987 were calculated on the basis of data used by ISTAT. In 1955 the incidence was 5.7 per 1000 whereas in 1987 this had fallen to 3.7 per 1000. In both years examined there was a prevalence of females (in 1987 females accounted for 4.3 per 1000 in comparison to 3 per 1000 recorded for for males). In 1987 the lowest incidence was recorded in the over 60 years olds, whereas the highest incidence was in males between 1 and 14 years old (7.57 per 1000) and females between 15 and 24 years old (12.17 per 1000). Mortality diminished from 0.42% in 1955 to 0.05% in 1987. The highest rate of mortality was recorded in those patients over 60 years old (1.5%).
