Endometrial abnormalities: evaluation with transvaginal sonography

Twenty-eight women with postmenopausal bleeding were retrospectively studied to assess the accuracy of transvaginal sonography (TVS) and hysteroscopy for diagnosing endometrial pathology. TVS was performed in all patients. Considering a cutoff value of < 5 mm as normal, TVS showed normal findings in 14 patients (50%) and suggested endometrial abnormalities in other 14 (50%). Hysteroscopy could be performed in 24 patients (85.7%). In 17 (70.2%) cases no abnormality was found; an endometrial polyp was suspected in 6 (25%) and endometrial hyperplasia in 1 (4.8%) patient. All patients underwent endometrial biopsy or dilatation and curettage for histopathologic study. Sensitivity, specificity, and positive and negative predictive values for TVS and hysteroscopy were 100, 60.8, 35.7, and 100% and 100, 89.4, 71.4, and 100%, respectively. In our experience, both methods were highly sensitive, but hysteroscopy was more specific than TVS.

“…Hysteroscopy using microhysteroscopes may allow di rect visualization of the uterine cavity without cervical dilatation, and the procedure can be performed in an out patient basis [5], More recently, transvaginal sonography (TVS) has greatly improved the accuracy in evaluating the endometrium by sonography [6,7],…”

Comparative Study of Transvaginal Ultrasonography and Hysteroscopy in Postmenopausal Bleeding

Alcázar

Laparte²

1996

“…Transvaginal ultrasonography is a relatively new endosonographic technique, whereby the use of high-frequency transducers results in higher resolution for better imaging of the endometrium, the uterus, and the ovaries [7][8][9]. The transvaginal technique is found to be useful in the evaluation of endometrial growth in fertile women and also in postmenopausal women in the diagnosis of endometrial cancer [10][11][12][13].…”

Transvaginal Ultrasonographic Evaluation of the Endometrium Related to the Histological Findings in Pre- and Perimenopausal Women

“…Transvaginal ultrasonography is a new endoscopic technique in which high-frequency transducers are placed in the vaginal vault to directly image pelvic struc tures [ 1 ]. The technique was initially developed to follow ovarian follicular maturation and guiding oocyte har vesting for in vitro fertilization [2,3].…”

Efficiency of Transvaginal Scanning in Obstetric and Gynecologic Fields

Hata

Hata²,

Aoki³

et al. 1990

Transvaginal ultrasonography was done on 26 pregnant women ranging from 5 to 27 weeks of gestation and 12 patients with gynecologic diseases. In early gestation, significant correlations were found among gestational age, crown-rump length, diameter of yolk sac and fetal heart rate. The maximal length of the gestational sac did not correlate with any other parameter. Transvaginal image quality was better in 76.2% in obstetric field and in 66.7 % in gynecologic field, as compared to findings with conventional abdominal ultrasonography, respectively. Fine structures and individual organs were better evidenced transvaginally. Therefore, transvaginal ultrasound affords pertinent information complementary to that obtained with the transabdominal technique.
