| PURPOSE : To analyze surgical specimens from patients with acute non-perforated and perforated appendicitis using
high-resolution ultrasonography (US), and to correlate the US features with the pathologic findings.
MATERIALS and METHODS : One hundred and six surgical appendix specimens obtained from patients with suspected
acute appendicitis were evaluated. The following US features were evaluated for differentiating acute non-perforated
appendicitis from perforated appendicitis: circumferential loss of the echogenic submucosal layer, disruption
of the serosal layer, asymmetrical wall thickening, the sum of opposing walls ≥ 9 mm and the presence
of appendicoliths. The sensitivity and specificity of the US findings for diagnosing perforated appendicitis were
determined.
RESULTS : All US features were detected significantly more often in the perforated appendicitis group of specimens.
The disruption of the serosal layer was the most significant independent predictor of perforation (p < .001). The
sensitivity for circumferential loss of the echogenic submucosal layer, disruption of the serosal layer, asymmetrical
wall thickening, wall thickness ≥ 9 mm, and the presence of appendicoliths individually was 84.6%,
69.2%, 61.5%, 73.1% and 46.2%, respectively. The specificity for all of these findings was 86.3%, 98.7%,
95.0%, 85.0% and 85.0%, respectively.
CONCLUSION : High-resolution US of appendiceal specimens was very useful for differentiating acute non-perforated
from perforated appendicitis. |
