Summary
Ultrasonography is a poor diagnostic tool for acute appendicitis, with low sensitivity. This study found it unreliable for evaluating patients with suspected appendicitis.
Area of Science:
- Medical Imaging
- Surgical Diagnosis
- Gastroenterology
Background:
- Acute appendicitis is a common surgical emergency.
- Accurate diagnosis is crucial for timely intervention and preventing complications.
- Diagnostic imaging modalities are frequently used to support clinical diagnosis.
Purpose of the Study:
- To evaluate the diagnostic accuracy of graded compression ultrasonography for acute appendicitis.
- To compare ultrasonographic findings with surgical outcomes in patients with suspected appendicitis.
Main Methods:
- Prospective clinical study involving 21 patients with a clinical diagnosis of acute appendicitis.
- Graded compression ultrasonography was performed on all patients.
- Ultrasonographic findings were compared with surgical findings.
Main Results:
- The study included 21 patients.
- Ultrasonography demonstrated 100% specificity but only 52.9% sensitivity.
- There were 8 false-negative results, indicating missed diagnoses of appendicitis.
- 9 true-positive and 11 true-negative results were recorded.
Conclusions:
- Ultrasonography is a poor modality for evaluating acute appendicitis.
- The low sensitivity suggests a significant rate of missed diagnoses.
- Findings contrast with some other studies, highlighting limitations of ultrasonography in this context.
