title: Laparoscopic evaluation of patients with suspected acute appendicitis.
abstract: BACKGROUND
  High error rates are reported in the clinical diagnosis of acute appendicitis. This study was undertaken to discover what additional value laparoscopy has in the diagnosis of suspected acute appendicitis.
  
  
  METHODS
  From April 1995 to November 1996, a diagnostic laparoscopy, before open appendicectomy, was performed in 100 consecutive patients with suspected acute appendicitis. Appendicectomy was performed only if the appendix showed signs of inflammation at laparoscopy or if the appendix could not be visualized.
  
  
  RESULTS
  Twenty-four patients were spared an appendicectomy, and in half of them a new diagnosis was established during laparoscopy. The rate of misdiagnosis was 41% in female patients of reproductive age and 8% in male patients. There were no cases of missed appendicitis in this trial, and all removed appendices showed signs of inflammation at histology.
  
  
  CONCLUSIONS
  It is safe to rely on the diagnosis made at laparoscopy. Its use for establishing diagnosis before appendicectomy in women of reproductive age is recommended.
