Ros C, de Guirior C, Mension E, et al. - Researchers herein evaluated the diagnostic preciseness of transvaginal sonography (TVS) in predicting the presence of deep endometriosis (DE) in the uterosacral ligaments (USLs), torus uterinus (TU) and posterior vaginal fornix (PVF) in women with suspected endometriosis scheduled for laparoscopic surgery. In addition, they determined the correlation of DE in other pelvic locations and linked symptoms with the presence of DE in the USLs, TU and PVF. Study participants were 172 women with clinically suspected or proven pelvic endometriosis who were scheduled for laparoscopic surgery. Findings revealed TVS to have correlation with high accuracy, sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio (LR+) and LH- for the assessment of DE in the USLs, TU and PVF. In Logistic regression analysis, they noted a significant correlation between DE in USL/TU/PVF and DE in the rectosigmoid.
