VP62.17: Ultrasonographic diagnosis of endometriosis associated at congenital uterine anomalies

According to the theory of retrograde menstruation, endometriosis would be due to the existence of Müllerian anomalies (MA) causing obstruction of the menstruation outflow tract. The aim of the present study to describe endometriosis findings in patients who had MA according ESHRE-ESGE consensus. From January 2018 to December 2019 a sample of patients with MA and endometriosis diagnosed by ultrasound were included. MA were classified according to the ESHRE-ESGE consensus of uterine anomalies. We recorded the presence of endometriosis in ovaries (OE), utero-sacral ligaments (USL), recto-sigmoid (RS), torus (T), vaginal fornix (VF) and anterior compartment (AC). The presence of each localisation of endometriosis was plotted against each class of anomaly. 226 uterine anomalies were diagnosed, of which 24 (10.61%) had endometriosis affectation. Relationship of endometriosis location and uterine anomaly and relative frequency (%) are shown in table 1. No findings of endometriosis in the anterior compartment or in the hypoplasia group (U5) were observed. The most prevalent MA were associated with endometriosis corresponds to U2 or septate uterus, frequently associated with ovary and recto-sigmoid locations. We believe that in patients with Müllerian anomalies a thorough search for endometriosis disease must be performed, especially in the cases of septate uterus. VP62.17: Table 1.
