Comparison of diagnostic accuracy of saline infusion sonohysterography, transvaginal sonography, and hysteroscopy in evaluating the endometrial polyps in women with abnormal uterine bleeding: a systematic review and meta-analysis

In women with abnormal uterine bleeding (AUB), endometrial polyps are a frequent finding, and the risk of a focal (pre)malignancy in a polyp is up to 6%. Because of this reported risk, the detection of polyps in these women is important. To evaluate and compare the diagnostic accuracy of saline infu...

Description
Summary:In women with abnormal uterine bleeding (AUB), endometrial polyps are a frequent finding, and the risk of a focal (pre)malignancy in a polyp is up to 6%. Because of this reported risk, the detection of polyps in these women is important. To evaluate and compare the diagnostic accuracy of saline infusion sonohysterography, transvaginal sonography, and hysteroscopy in detecting endometrial polyps in women with AUB. The searches were conducted by two independent researchers to find the relevant studies published from 1/1/2009 until the end of 30/06/2019. We searched for published literature in English language in MEDLINE, EMBASETM, The Cochrane Library, and Trip database. For literature published in other languages, we searched national databases (Magiran and SID), KoreaMed, and LILACS. The risk of bias of every article was evaluated by using QUADAS-2. After selection and quality assessment, 11 studies were included. Based on the random effect model the total prevalence of endometrial polyps in women with abnormal uterine bleeding was 38%. The sensitivity and specificity of saline infusion sonohysterography in diagnosis of endometrial polyps were 0.87 and 0.86, respectively. The sensitivity and specificity of transvaginal ultrasonography were 0.62 and 0.73 and the sensitivity and specificity of hysteroscopy were 0.92 and 0.85, respectively. Although that sonohysterography is a safe and relatively cheap method, which allows ruling out or confirming endometrial polyps, it cannot be replaced with hysteroscopy due to the fact that hysteroscopy combined with biopsy is the gold standard for ruling out malignancies in an endometrial polyp.
