[Clinical aspects of appendicitis]

When evaluating 4232 appendectomies between 1977-1986 there were 12.5% perforations and in 19.3% the diagnosis was not justified. In 5.1% surgical intervention was done without acute appendicitis. The overall lethality was 0.5%, the cases of perforation 2.3%. The diagnosis of lethality was cardiopulmonary disease. In this follow up study we discuss possibilities of giving a secure diagnosis.
