Ultrasound may spot endometriosis without surgery
NCT ID NCT07427849
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a specific ultrasound measurement can reliably detect superficial endometriosis on the uterosacral ligaments. Researchers will compare ultrasound findings with laparoscopic surgery results in 64 women undergoing gynecological surgery. If a clear cutoff thickness is found, it could lead to a non-surgical diagnostic tool.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could establish a reliable ultrasound cutoff to diagnose superficial endometriosis without surgery, enabling earlier and less invasive detection.
- What could go wrong
- This is an observational study with only 64 participants, so results may not apply to all patients. The ultrasound cutoff may not be accurate enough to replace laparoscopy in practice.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
the study is conducted in patients of childbearing age undergoing laparoscopic surgery for benign or malignant gynecological pathology in early stage. The study does not include changes to the standard care pathway. The indication for surgical treatment is given following the most up-to-date guidelines on the subject. Patients who are younger, postmenopausal, or have undergone previous pelvic surgery are excluded as these factors could alter the anatomy and ultrasound evaluation of LUS (uterosacral ligament).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * patients who need to undergo gynecological surgery with a laparoscopic approach for benign pathology (endometriosis, uterine fibroids, adenomyosis, chronic pelvic pain, benign ovarian cysts) or non-advanced malignant pathology (stage I endometrium and cervix, stage I and II ovary). * patients who performed a level II gynecological ultrasound with an experienced operator in the preoperative pathway. * technical possibility of performing a transvaginal ultrasound and the patient's willingness to undergo such an investigation. * patients of childbearing age (18 - 50 years). * Signing of informed consent. Exclusion Criteria: * presence of endometriosis deeply infiltrating the posterior compartment. This may interfere with the interpretation of uterosacral ligament (LUS) thickness as a specific marker of superficial endometriosis * technical impossibility of performing a transvaginal ultrasound (patient virgo, patient refusal). * incomplete ultrasound evaluation of the uterosacral ligaments for anatomical reasons or for the presence of endometriosis nodules from other sites with partial involvement of the LUS (uterosacral ligament). * advanced malignant disease (\>Stage I for endometrium and cervix, \> Stage II for ovary) * pelvic organ prolapse * PID or other pelvic inflammatory diseases * medical emergencies (ovarian torsion, hemoperitoneum) * postmenopausal patients * previous pelvic surgery
