Validation and Comparison of the Appendicitis Inflammatory Response Score and Adult Appendicitis Score
Validation and Comparison of the Appendicitis Inflammatory Response Score and Adult Appendicitis Score
Acute appendicitis is one of the most frequent reasons of emergency laparotomy in adults.
 Symptoms of acute appendicitis overlap with other clinical conditions and might present as a
 challenge, especially in the early phases. Despite the advances and widespread use of imaging
 modalities, still negative laparotomies are performed with the initial diagnosis of acute
 appendicitis. Several scoring systems are developed by using various clinical and laboratory
 parameters in order to improve the diagnostic accuracy and prevent unnecessary laparotomies.
In the recent guideline of World Society of Emergency Surgeons (WSES) recommendations
 regarding the clinical scoring systems for acute appendicitis are remarkable. It is stated
 that clinical scoring systems, on their own, can be used to exclude acute appendicitis and
 decrease negative laparotomy rates. Currently Appendicitis Inflammatory Response Score (AIR)
 and Adult Appendicitis Score (AAS) are the best clinically performing scoring systems. As a
 result, based on strong evidence the use of these two systems are recommended. Both scoring
 systems are developed on the basis of clinical findings and laboratory parameters.

 The aim of this study is to validate both systems as well as to compare the efficiency of
 both systems on excluding negative laparotomies and on the determination of severity of acute
 appendicitis.
