Validation and Comparison of the Appendicitis Inflammatory Response Score and Adult Appendicitis Score

Completed

• Conditions: Acute Appendicitis; Acute Appendicitis With Rupture
• Interventions: Diagnostic Test: Appendicitis Inflammatory Response; Diagnostic Test: Adult Appendicitis Score

• Registration Number: NCT04730752
• Lead Sponsor: Nigde Omer Halisdemir University

Brief Summary

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.

Detailed Description

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.
