Gerges B, Li W, Leonardi M, et al. - Researchers investigated the diagnostic accuracy and ascertained the optimum imaging modality for the identification of rectosigmoid deep endometriosis (DE) in women with a clinical history of endometriosis. Via conducting a systematic review using PubMed, Medline, Scopus, Embase and Google Scholar, they identified 1,977 references; out of these, 30 studies (n = 3,374) were included in the analysis. Findings suggest slightly better sensitivity of transvaginal sonography (TVS) for the detection of DE than magnetic resonance imaging (MRI), although transrectal endoscopic sonography was noted to be superior to both of these. Both TVS and MRI were noted to have excellent specificity. As TVS is the simpler, faster, and more readily available tool, it is supported to be the first line diagnostic tool for the women with suspected DE.
