Purpose:
The aim of this study is to investigate the correlation between the magnetic resonance imaging (MRI) and intraoperative findings of deep infiltrating endometriosis using the #ENZIAN score.
Methods:
This retrospective study included 64 patients who underwent surgery for deep infiltrating endometriosis between January 2017 and August 2020. Preoperative abdominopelvic MRI assessment was evaluated and scored using the #ENZIAN classification. Operative scores were considered the gold standard, and the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of MRI for each category were calculated.
Results:
MRI has higher sensitivity and specificity in showing the lesions of the compartments O (ovarian lesions), A (rectovaginal septum and posterior vaginal fornix), and B (uterosacral ligaments and parametrium) (100-100%, 100-100%, and 97-100%, respectively, p < 0.001) compared to the other compartments. The lowest sensitivity, specificity, accuracy, and PPV of the MRI was found in compartment P (14%, 76%, 70%, and 7%, respectively).
Conclusion:
We demonstrated that the #ENZIAN classification in MRI reports has significant sensitivity and specificity in compartments A, B (uterosacral ligaments and parametrium), and O. Furthermore, the determination of peritoneal lesions via MRI is inadequate.
Insights
Magnetic resonance imaging (#MRI) using the #ENZIAN score effectively identifies deep infiltrating endometriosis lesions in ovarian, rectovaginal septum, and parametrial compartments. However, MRI is less accurate for detecting peritoneal lesions.
Area of Science:
- Gynecologic imaging
- Surgical assessment
- Endometriosis classification
Background:
- Deep infiltrating endometriosis (DIE) requires accurate preoperative assessment for surgical planning.
- The #ENZIAN score is a classification system used to standardize the evaluation of DIE.
- Correlation between preoperative imaging and intraoperative findings is crucial for DIE management.
Purpose of the Study:
- To evaluate the accuracy of magnetic resonance imaging (#MRI) in assessing deep infiltrating endometriosis using the #ENZIAN score.
- To compare #MRI findings with intraoperative surgical data.
- To determine the sensitivity and specificity of #MRI for different DIE compartments.
Main Methods:
- Retrospective analysis of 64 patients with DIE who underwent surgery.
- Preoperative abdominopelvic #MRI was scored using the #ENZIAN classification.
- Surgical findings served as the gold standard to calculate diagnostic performance metrics (sensitivity, specificity, PPV, NPV).
Main Results:
- #MRI demonstrated high sensitivity and specificity for ovarian (O), rectovaginal septum (A), and parametrial (B) compartments (97-100%).
- The #ENZIAN classification on #MRI showed excellent performance in compartments O, A, and B.
- MRI exhibited low sensitivity and accuracy for detecting peritoneal lesions (compartment P).
Conclusions:
- The #ENZIAN classification via #MRI is a reliable tool for evaluating DIE in specific anatomical locations.
- #MRI is highly sensitive and specific for ovarian, rectovaginal septum, and parametrial DIE.
- Preoperative #MRI assessment of peritoneal DIE requires further refinement.
