Accuracy of transvaginal ultrasound for diagnosis of deep endometriosis in the rectosigmoid: systematic review and meta‐analysis

Abstract

Objectives To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of rectosigmoid endometriosis in patients with clinical suspicion of deep infiltrating endometriosis (DIE), comparing enhanced (E-TVS) and non-enhanced approaches. Methods 97% (95%CI,[95][96][97][98] 33.0 (95%CI,, respectively. Significant heterogeneity was found for sensitivity (I 2 , 90.8%; Cochran Q, 195.2; P < 0.001) and specificity (I 2 , 76.8%; Cochran Q, 77.7; P < 0.001). We did not find statistical differences between

Transvaginal ultrasound vs magnetic resonance imaging for diagnosing deep infiltrating endometriosis: systematic review and meta‐analysis

“…Comparing with the other published meta‐analyses, we observed lower sensitivities than did Nisenblat et al . for both methods (90% for TVS and 92% for MRI) and Guerriero et al . for TVS (91%), while our overall sensitivity was similar to that of Noventa et al .…”

“…With respect to the diagnostic performance of TVS and MRI for the detection of DIE involving the rectosigmoid, the pooled sensitivity, specificity, LR+ and LR– of the two techniques were similar, with 85% sensitivity for both MRI and TVS and specificity of 95% and 96%, respectively. Comparing with the other published meta‐analyses, we observed lower sensitivities than did Nisenblat et al . for both methods (90% for TVS and 92% for MRI) and Guerriero et al .…”

Sonographic Pitfall in Endometriotic Ovarian Cysts: A Rare Case of a Spontaneous Sigmoid Colonic Perforation in a Nonpregnant Woman

“…3 Transvaginal sonography is considered an effective technique for staging pelvic endometriosis. 8 In this case, the periovarian abscess was multilocular, with low-level echogenicity and poor peripheral vascularization (color score of 2). The sonographic features of typical endometriomas are the presence of a unilocular cyst with "ground glass" echogenicity and no or poor peripheral vascularization (color score of 1 or 2).…”

To determine the optimal ultrasonographic screening method for rectal/rectosigmoid deep endometriosis: Ultrasound “sliding sign,” transvaginal ultrasound direct visualization or both?

“…Deep endometriosis (DE) is defined as the presence of endometrial subperitoneal implants of ≥5 mm and can occur in the rectum/rectosigmoid bowel, uterosacral ligaments (USL), rectovaginal septum (RVS), vagina and/or bladder . Bowel endometriosis involvement is estimated to occur in 5.3‐12% of women with endometriosis, and the rectum and rectosigmoid junction together account for 70‐93% of all intestinal endometriotic sites …”
