OP18.02: Hysterosalpingo‐contrast‐sonography for tubal patency assessment in patients with endometriosis

Material and methods This study was based on the retrospective analysis of a prospectively collected database of patients with endometriosis who underwent HyCoSy and subsequently had tubal patency assessment during laparoscopy. Patients had histological diagnosis of endometriosis. At the time of ultrasonography, a standardized assessment of the presence of deep endometriosis and ovarian endometriomas was performed. Exclusion criteria for the study were: ultrasonographic diagnosis of hydrosalpinx, previous uni or bilateral adnexectomy or salpingectomy, major uterine malformations. The intensity of pain perceived during HyCoSy was assessed by visual analogue scale (VAS). The findings of HyCoSy were compared with surgical assessment of tubal patency. The McNemar's test was used to compare the diagnostic performance of the two exams. These findings were confirmed when the analysis was restricted to patients with ovarian endometriomas (p =0.247). Overall, 156 patients (57.1%) did not complain any pain during HyCoSy; mild pain (VAS score < 3) was reported by 62 patients (22.7%); 38 patients (13.9%) complained moderate pain (VAS score 4-7) and 17 patients (6.2%) had severe pain (VAS > 7).
