Eighty-one cases of acute appendicitis in children aged less than six
years were identifled in the Belfast urban area between 1985 and 1992.
Appendiceal perforation, found in 43%, was related to symptom duratio
n but not to age at presentation. Prolongation of symptoms was related
to parental delay in seeking medical advice (52% > 36 hours), delayed
or inappropriate general practitioner referral to hospital (19%) and
diagnostic delay following surgical consultation (12% > 12 hours). Dia
gnostic delay in hospital was usually the result of nonspecificity of
symptoms and signs and was therefore largely unavoidable. Delayed refe
rral from general practice did not contribute unnecessarily to appendi
ceal perforation, and given that an individual general practitioner wi
ll see a case of preschool appendicitis once in 30 years, diagnostic a
ccuracy was remarkably high.
