Comparing CT scan reports and the AIR score in adults having an appendectomy for suspected appendicitis.

Prospective Evaluation of the Impact of Computed Tomography Reporting and AIR Scoring System on Negative Appendectomy Rates in Patients With Acute Appendicitis

Observational Sanliurfa Education and Research Hospital · NCT07496723

This will try to see if CT scan reports and the Appendicitis Inflammatory Response (AIR) score can accurately identify true appendicitis in adults who have an appendectomy after a CT suggests appendicitis.

What this trial studies

This single-center prospective observational study enrolls adults presenting to the emergency department who receive a CT scan reported as compatible with acute appendicitis and subsequently undergo appendectomy. Clinical and demographic data, routine labs, and AIR score components are collected prospectively, and CT findings are taken from routine radiology reports. Surgeons will grade intraoperative severity using the AAST appendicitis scale and final diagnosis will be based on histopathology. The primary outcome is the negative appendectomy rate, with secondary analyses comparing agreement and diagnostic performance between AIR score, CT reports, intraoperative grading, and pathology across subgroups.

Who should consider this trial

Good fit: Adults aged 18 years or older who had a CT reported as compatible with appendicitis and then underwent appendectomy after emergency department evaluation.

Not a fit: Patients taken directly to surgery without a preoperative CT, children, pregnant patients, or those with other intraoperative pathologies are excluded and will not benefit from this study's findings.

Why it matters

Potential benefit: If successful, this could help reduce unnecessary appendectomies and improve diagnostic confidence by clarifying how CT reports and the AIR score agree with pathology.

How similar studies have performed: Prior research shows CT and clinical scores like the AIR score can lower negative appendectomy rates, but prospective single-center data specifically linking CT reports, AIR score, intraoperative grading, and pathology are limited.
