Appendectomy Clinical Trials

Acute appendicitis is one of the most common surgical emergencies, but diagnostic uncertainty may still lead to unnecessary appendectomy in some patients. This prospective observational study aims to evaluate the diagnostic performance of computed tomography (CT) reporting and the Appendicitis Inflammatory Response (AIR) score in adult patients undergoing appendectomy for suspected acute appendicitis. The primary objective is to determine the negative appendectomy rate based on final histopathology. Secondary objectives are to assess the agreement between AIR score, CT findings, intraoperative severity grading, and pathology results, and to explore diagnostic performance across patient subgroups. No study-specific intervention beyond routine clinical care will be performed.
