Transvaginal sonography demonstrated 88% diagnostic accuracy for pelvic endometriosis, with high specificity (95%) and sensitivity (53%), particularly for deep endometriosis.

This prospective study evaluated the diagnostic accuracy of transvaginal sonography (TVS) compared with laparoscopy as the gold standard in women scheduled for laparoscopy due to infertility assessment. Consecutive participants underwent preoperative TVS and laparoscopic findings were used to calculate sensitivity, specificity, positive and negative predictive values, and overall accuracy for pelvic endometriosis, including deep disease. Among 262 women (78 with endometriosis), TVS showed 53% sensitivity and 95% specificity, with PPV 63% and NPV 92%, yielding 88% diagnostic accuracy; the authors report that TVS performed particularly well for deep endometriosis. The paper does not explicitly discuss limitations in the provided text. This paper is centrally about endometriosis — it assesses TVS accuracy against laparoscopy for pelvic and deep endometriosis diagnosis.

Abstract

Background: To evaluate diagnostic accuracy of transvaginal sonography and laparoscopy in the diagnosis of endometriosis. Patients and Methods: This was a prospective study of women scheduled for laparoscopy because of infertility assessment. Consecutive patients were assessed prospectively using TVS before laparoscopy and the findings of preoperative TVS were compared with the results obtained by laparoscopy as a gold standard. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values, and accuracy were calculated for the diagnosis of endometriosis. Results: In total, 262 women (mean age 31 + 4.47) had preoperative TVS and laparoscopies. Of these, 78 had endometriosis. Diagnostic accuracy was assessed; the sensitivity and specificity of the TVS in the diagnosis of pelvic endometriosis were 53% and 95%, respectively, and the positive and negative predictive value were 63% and 92%, respectively. The diagnostic accuracy was 88%. Conclusions: TVS is a good test for assessing pelvic endometriosis. Good specificity and sensitivity were obtained in the diagnosis of deep endometriosis. TVS is particularly accurate in detecting deep endometriosis, which could facilitate more effective triaging of women for appropriate surgical care.
