VP62.08: Ultrasound diagnosis of tubo‐ovarian endometriosis and its adhesion status

To determine the accuracy and impact of ultrasound in the diagnosis of ovarian endometriosis and its adhesion status in surgical specimen. Retrospective analysis of surgical interventions, anatomopathological specimen and ultrasound diagnosis in women diagnosed of endometriosis during the last 3 years (2017–2019). During the study period we performed 450 tubo-ovarian surgical procedures (cystectomies, oophorectomies or adnexectomies), 100 of which were related to ovarian endometriosis (22.22%). In 60 patients (60.0%) there was a moderate-severe adhesion status described in surgical procedures (moderate: N: 34, 34.0%; severe: N: 26, 26.0%), while in 40 cases (40.0 %) there were none (N:33) or mild (N:7) adhesions. Of the 67 cases of women with any adhesion status, not specially trained sonographers without a special protocol for detecting pelvic adhesions, in only 14 cases made a reference in their diagnosis (20.9%). Most of the women (79.1%) had surgery without having the information of a possible adhesion status that would complicate the surgery. Some surgeries in cases of moderate-severe pelvic adhesions were unsuccessful because of complexity, required experienced surgeons and took a longer time in the operating room. Tubo-ovarian endometriosis can be frequently associated with pelvic adhesions. Sonographers suspecting tubo-ovarian endometriosis should follow a protocol of exploration in order to discard a moderate-severe adhesion status which can be an important item for surgeons to plan surgery.
