Transvaginal Sonography for the Preoperative Assessment of Parametrial Deep Infiltrating Endometriosis: A Diagnostic Accuracy Study.

TVS performed following a systematic approach for assessing the lateral parametria seems to have good diagnostic accuracy for PE with large changes in the posttest probability of parametrial involvement based on the TVS evaluation. Considering the clinical and surgical implications of PE, further studies implementing a standardized approach for assessing the parametrium by TVS are recommended to confirm our observations and implement a standardized protocol in clinical practice.
