This systematic review and meta-analysis evaluated the diagnostic performance of saline/gel sonovaginography (SVG) for detecting deep infiltrating endometriosis (DE) in the posterior compartments among 1221 patients across 10 studies. The analysis revealed a pooled specificity of 99% and sensitivity of 82% for rectovaginal septum lesions, and a specificity of 96% and sensitivity of 87% for rectosigmoid lesions.
Key findings
- For rectovaginal septum lesions, pooled specificity was 99% and sensitivity was 82%.
- Rectosigmoid lesions showed a specificity of 96% and sensitivity of 87%.
- Vaginal fornices had a perfect specificity of 99% but moderate sensitivity of 65%.
- Uterosacral ligament lesions had the lowest diagnostic odds ratio at 31.45.
Why it matters
The findings highlight the effectiveness of SVG as a non-invasive and cost-effective method for accurately diagnosing deep infiltrating endometriosis, which is crucial for treatment planning and improving patient outcomes.
