To assess the efficiency of transvaginal ultrasonography in the screening of endometriomas and in differentiating endometriomas from other ovarian masses.
Prospective study with surgical and pathological confirmation of the sonographic diagnosis.
Department of Obstetrics and Gynecology at the University of Cagliari, Cagliari, Italy.
All premenopausal nonpregnant women (n = 236) submitted to laparotomy or laparoscopy from May 1991 to December 1992.
Transvaginal ultrasonographic examinations were done within 1 week before surgery. Ultrasonographic diagnosis was compared with surgical and histopathological findings.
The visualization of round-shaped homogeneous hypoechoic "tissue" of low-level echoes within the ovary was chosen as characteristic ultrasonographic finding of endometrioma. Sensitivity, specificity, and predicted values were calculated for each visualized ovary (group A) to assess the efficiency in the screening, and for each visualized cyst (group B) to assess the efficiency in differentiating endometriomas from other ovarian masses.
Four hundred twenty-three of 466 ovaries were visualized. Of the 82 visualized cysts, 27 were suspected to be endometriomas, and the diagnosis was confirmed by pathology in 21. The sensitivity and the specificity were 75% and 99%, respectively, in group A, and 84% and 90%, respectively, in group B.
The study demonstrates that transvaginal ultrasonography has an efficiency of 88% in differentiating endometriomas from other ovarian masses with a specificity of 90%.
评估经阴道超声检查在子宫内膜异位囊肿筛查以及将子宫内膜异位囊肿与其他卵巢肿物相鉴别方面的效能。
一项通过手术及病理检查对超声诊断进行确认的前瞻性研究。
意大利卡利亚里市卡利亚里大学妇产科。
1991年5月至1992年12月期间接受剖腹手术或腹腔镜检查的所有绝经前非妊娠女性（n = 236）。
在手术前1周内进行经阴道超声检查。将超声诊断结果与手术及组织病理学检查结果进行比较。
将卵巢内圆形均匀低回声“组织”的可视化表现选为子宫内膜异位囊肿的特征性超声表现。计算每个可视化卵巢（A组）的敏感性、特异性和预测值，以评估筛查效能；计算每个可视化囊肿（B组）的敏感性、特异性和预测值，以评估将子宫内膜异位囊肿与其他卵巢肿物相鉴别的效能。
466个卵巢中，423个可被可视化。在82个可视化囊肿中，27个疑似为子宫内膜异位囊肿，其中21个经病理确诊。A组的敏感性和特异性分别为75%和99%，B组的敏感性和特异性分别为84%和90%。
该研究表明，经阴道超声检查在将子宫内膜异位囊肿与其他卵巢肿物相鉴别方面的效能为88%，特异性为90%。
