Brief Summary:
The diagnosis of acute appendicitis is difficult and despite important advances in medical sciences, detailed patient questioning and precise medical examination are the main keystones of the diagnosis of acute appendicitis and up to now, results still unsatisfactory.

Condition or disease Intervention/treatment
Appendicitis Biological: C-reactive protein measurement

Detailed Description:

Acute appendicitis is the most common surgical emergency and the most common source of community-acquired intra-abdominal infections. The lack of accuracy in the diagnosis of acute appendicitis yields often to two types of outcomes: a delay in diagnosis leads to perforation and peritonitis in up to 15% of the cases and unnecessary appendectomy is associated with post-operative complications such as wound infection and adhesions. CRP is an acute phase protein that is often used by many surgeons as a diagnostic marker of acute appendicitis. During the evaluation of patients with possible appendicitis in the emergency department (ED), repeated physical examination of the abdomen may provide further information about the decision making. However, the role of repeated laboratory examinations is not proven.

The purpose of this study was to investigate whether repeated serum CRP measures could be useful to predict acute appendicitis, after 3 hours of observation, in comparison with the histopathological findings.

Group/Cohort Intervention/treatment
Acute appendicitis
all patients admitted to our hospital with a clinically suspected acute appendicitis.
Biological: C-reactive protein measurement
All patients included in this study underwent a blood sample analysis for C-reactive protein concentrations at admission and 3 hours later.

Primary Outcome Measures :
  1. Final diagnosis of acute appendicitis [ Time Frame: 15 days from patients inclusion ]
    The final diagnosis of acute appendicitis was based, in operated patients, on the results of the histologic examination of the excised appendix and, in non operated patients, on the absence of acute appendicitis at the 2 weeks follow-up visit.
