[Acute appendicitis. Preoperative observation time and diagnostic accuracy].
The indication for operative treatment of suspected acute appendicitis is based mainly on clinical examination. In this retrospective study of 327 emergency laparotomies the accuracy of the surgeons diagnosis was 69.4%. The overall rate of unnecessary laparotomy was 28.4%, and 45.6% of the operated females, aged 12 to 40 years, did not actually require surgery. The median postadmission delay before operation was three hours 28 minutes. With increasing observation time, the diagnostic accuracy was significantly decreased from 77.7 to 52.2%, and the incidence of perforation rose from 18.6 to 33.3%. 8.7% of the patients with a surgical condition suffered from excessive delay (greater than 12 hours) before surgery. There was no correlation between time of admission and operation and accuracy of diagnosis, but a considerable variation in accuracy between different surgeons. The difficulty in obtaining a correct pre-operative diagnosis in patients with suspected acute appendicitis is still a clinical problem of major concern.
