Diagnostic accuracy of hysterosalpingo-foam-sonography to confirm tubal occlusion after Essure (R) placement as treatment for hydrosalpinges

摘要

Consensus globally is that hydrosalpinges need to be treated before IVF owing to their negative influence on outcomes. The current standard treatment is laparoscopic salpingectomy. A potential less invasive treatment is proximal occlusion of a hydrosalpinx by hysteroscopic placement of an Essure (R) device. Tubal occlusion after Essure (R) placement needs to be verified by hysterosalpingography (HSG). However, this is a painful examination, that exposes patients to radiation. Hysterosalpingo-foam sonography (HyFoSy) is a less invasive alternative test to confirm proximal tubal occlusion. This prospective diagnostic accuracy study evaluated if HyFoSy is as accurate as HSG to confirm proximal tubal occlusion after placement of an Essure (R) device as treatment for a hydrosalpinx before IVF. Thirty-eight treated hydrosalpinges in 26 women were evaluated. Proximal occlusion was verified by HyFoSy (index test) and HSG (standard reference). The accuracy of HyFoSy was 97.4% (95% CI 92.3% to 100.0%). Sensitivity and specificity were 97.1% (95% CI. 84.6% to 99.5%) and 100.0% (95% CI 40.2% to 100.0%), respectively. After an Essure (R) device is placed as treatment for a hydrosalpinx before IVF, HyFoSy is as able as HSG to confirm proximal tubal occlusion. If HyFoSy demonstrates tubal patency, a subsequent HSG needs to be carried out to validate this finding. (C) 2014 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.
