Evaluation of a Combination Study of a Noninvasive Scoring System and Transrectal Ultrasonography to Detect Deeply Infiltrating Endometriosis

Objective:  Noninvasive evaluation must be required for deeply infiltrating endometriosis, typically accompanied by pelvic pain, dyspareunia, and bowel retraction. To explore noninvasive diagnostic methods for deeply infiltrating endometriosis, we employed a combination study of a diagnostic scoring system and transrectal ultrasonography.
Methods:  A prospective diagnostic study was designed for deeply infiltrating endometriosis by noninvasive diagnostic scoring and transrectal ultrasonography ( n  = 40).
Results:  Sixteen out of twenty-four women with positive points in the diagnostic scoring had deeply infiltrating endometriosis on uterosacral ligaments. Uterosacral ligaments were thickened in 83.3% of patients with deeply infiltrating endometriosis on uterosacral ligaments. The patients who had both thickened uterosacral ligaments and a positive diagnostic score were limited to patients with deeply infiltrating endometriosis on uterosacral ligaments.
Conclusion:  Our findings showed that thick uterosacral ligaments associated with a positive diagnostic score strongly designated that the women were affected by deeply infiltrating endometriosis. It is concluded that this combination study has clinical diagnostic value for deeply infiltrating endometriosis at the outpatient department.
