VP62.32: Prevalence of endometriosis at transvaginal ultrasound in women with dyspareunia

To determine the prevalence of endometriosis detected at ultrasound examination in different localisations in women with dyspareunia and suspected endometriosis. Women with dyspareunia and suspected endometriosis underwent transvaginal ultrasound examination by experienced examiner in 2014–2019. Ultrasound examinations were performed using GE E8 and E10 ultrasound machines with vaginal transducer of 5-9 MHz according to standardised endometriosis examination protocol. All abnormal findings in the uterus, ovaries, bowels, urinary bladder, sacrouterine ligaments were noted and their size, location, tenderness and mobility described. Women were asked about their symptoms (dyspareunia, dysmenorrhoea, chronic pelvic pain, dyschezia, dysuria) and hormonal treatment. Out of 556 women with moderate to severe dyspareunia, 73 women were excluded because of previously known endometriosis. Out of 483 women included, 224 (46%) had normal ultrasound findings, 138 (29%) had visible endometriosis in the pelvis and 121 (25%) women had other pathological findings. Endometriosis was found in only one anatomical location in 57% (79/138), in two or more locations in 43% (59/138). Endometrioma and adenomyosis were found in 54% (74/138) and 38% (53/138) of women, respectively. The prevalence of deep endometriosis in the bowel, sacrouterine ligaments with pouch of Douglas, rectovaginal septum and urinary bladder were 35%, 34%, 9% and 2%, respectively. Obliteration of pouch of Douglas was found in 14% (19/138) women. Almost one of three women with dyspareunia and clinically suspected endometriosis seeking for medical care had endometriosis features at ultrasound examination. Most women had one location of endometriosis and the most common finding was endometrioma.
