Diagnostic Accuracy of Ultrasonography in Diagnosis of Acute Appendicitis in Pediatric Population

Background: One of the most frequent reasons why children require emergency abdominal surgery is acute appendicitis. In order to avoid problems including perforation, abscess formation, and needless surgery, an accurate and prompt diagnosis is essential. Because it is non-invasive and radiation-free, ultrasound (USG) is commonly utilized as a first imaging modality, particularly for young patients. Objective: The purpose of this study was to compare sonographic findings with intraoperative and histological data in order to assess the diagnostic accuracy of ultrasonography in identifying acute appendicitis in the pediatric population. Methodology: Over the course of six months, a qualitative study was carried out in a tertiary care hospital's emergency room from November 2024 to May 2025. Ultrasonography was performed on 130 children, ages 5 to 18, who had a clinical suspicion of appendicitis. To evaluate sensitivity, specificity, and predictive qualities, USG results were contrasted with surgical and histological results. Results: The results showed that ultrasonography had a 90.2% sensitivity, 57.1% specificity, 88.5% positive predictive value, and 61.5% negative predictive value. Non-compressible tubular structure >6 mm (75.4%) and wall thickening (70.8%) were common sonographic findings. 102 cases (78.5%) had appendicitis confirmed by final diagnosis; the stages included suppurative, gangrenous, and perforated types. Conclusion: Ultrasonography is a safe, dependable, and reasonably priced method for identifying children's acute appendicitis early on. Even if it depends on the operator, it is essential for directing clinical judgements and minimizing needless procedures, especially in environments with limited resources.
