Summary
Sonography demonstrates high diagnostic accuracy for acute appendicitis, with 97.5% sensitivity and 95.12% specificity. This imaging approach aids in managing appendicitis cases, reducing unnecessary surgeries.
Area of Science:
- Medical Imaging
- Diagnostic Ultrasound
- Surgical Gastroenterology
Background:
- Acute appendicitis is a common surgical emergency.
- Accurate diagnosis is crucial to avoid complications and negative laparotomies.
- Sonography is a widely available imaging modality.
Purpose of the Study:
- To evaluate the diagnostic value of sonography in patients presenting with clinical signs of acute appendicitis.
- To assess the effectiveness of sonographic parameters in guiding surgical management.
Main Methods:
- Retrospective analysis of patients with suspected acute appendicitis.
- Sonographic evaluation of appendiceal morphology, maximal diameter, and wall thickness.
- Correlation of sonographic findings with clinical presentation and surgical outcomes.
Main Results:
- Sonography achieved a sensitivity of 97.5% and a specificity of 95.12% for diagnosing acute appendicitis.
- Morphological assessment and measurement of the appendix and its wall were key diagnostic indicators.
- Integration of sonographic data with clinical findings facilitated restrictive surgical management.
Conclusions:
- Sonography is a highly accurate tool for diagnosing acute appendicitis.
- Ultrasound findings, combined with clinical assessment, can effectively guide treatment decisions.
- Utilizing sonography reduces the rate of negative laparotomies in suspected appendicitis cases.
