Background: Endometriosis is one of the most common gynecological disorders, which causes pain and reduces fertility. An accurate diagnostic technique would be helpful in the management of these patients preoperatively. The objective of this study was to do a comparative evaluation of uterosacral involvement in deep infiltrative endometriosis by transvaginal sonography (TVS) and laparoscopic biopsy.
Methods: TVS and laparoscopy were done in all patients suspected to have endometriosis. TVS examination was carried out to identify endometriotic lesions, and in suspicious laparoscopic views, biopsy was done and laparoscopic findings were confirmed by pathologic report. Then, TVS and pathological findings in laparoscopy were compared and data analyzed by SPSS Version 23.
Results: In our study on 80 patients, the mean age was 34.47 ± 5.94 (mean ± SD) years. Comparison of ultrasound with laparoscopic examinations showed that ultrasound as the gold standard method, has sensitivity, specificity, and positive and negative predictive values of 93%, 65%, and 87%, and 78.9%, respectively, while in the diagnosis of increased uterosacral ligament thickness showed 82%, 100%, and 100% and 6.66%, respectively. While in the diagnosis of nodules in the uterosacral ligament, 100% for all four parameters in the diagnosis of endometrioma in the ovaries, and 71%, 96.4%, and 97.3% and 64.2%, respectively, in the diagnosis of rectal, bladder, and ureteral involvement.
Conclusion: TVS can be used in the diagnosis of endometriosis by examining the increase in the thickness of the uterosacral ligament and the presence of hypoechoic nodules in it; also, this method demonstrates acceptable sensitivity and specificity in ovarian endometrioma. |
