Emergency appendicectomy: a one year audit

A retrospective study of emergency appendicectomy over a one-year period at Beaumont Hospital was carried out. The overall normal appendicectomy rate was 22.8%, and was twice as high in women (31%) as in men (15%). Gangrenous or perforated appendicitis was present in 20% of cases. The overall mean assessment-surgery interval was 16.7 hours. Considerable variation in the use of antimicrobial agents was noted in the study, and many haematological and radiological investigations performed did not appear to improve diagnostic accuracy. Among patients with clinical features typical of appendicitis, 16% proved to have a normal appendix. These results point to a number of aspects of the diagnosis and management of appendicitis where there appears to be room for future improvement.
