Abstract
OBJECTIVE To compare the diagnostic performance of two-dimensional transvaginal sonography (TVS) and saline contrast sonohysterography (SCSH) for the diagnosis of endometrial polyps in studies that used both tests in the same group of patients. METHODS This was a systematic review and meta-analysis. An extensive search was conducted of Medline (PubMed), Cochrane Library and Web of Science, for studies comparing the diagnostic performance of TVS and SCSH for identifying endometrial polyps, published between January 1990 and December 2019, that reported a definition of endometrial polyp on TVS and SCSH and used pathologic analysis as the reference standard. Quality of the included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. A random-effects model was used to determine pooled sensitivity, specificity and positive and negative likelihood ratios of TVS and SCSH in the detection of endometrial polyps. Subanalysis according to menopausal status was performed. RESULTS In total, 1278 citations were identified; after exclusions, 25 studies were included in the meta-analysis. In the included studies, the risk of bias evaluated using QUADAS-2 was low for most of the four domains, except for flow and timing, which had an unclear risk of bias in 13 studies. Pooled sensitivity, specificity and positive and negative likelihood ratios for TVS in the detection of endometrial polyps were 55.0% (95% CI, 46.0-64.0%), 91.0% (95% CI, 86.0-94.0%), 5.8 (95% CI, 3.9-8.7) and 0.5 (95% CI, 0.41-0.61), respectively. The corresponding values for SCSH were 92.0% (95% CI, 87.0-95.0%), 93.0% (95% CI, 91.0-95.0%), 13.9 (95% CI, 9.9-19.5) and 0.08 (95% CI, 0.05-0.14), respectively. Significant differences were found when comparing the methods in terms of sensitivity (P < 0.001), but not for specificity (P = 0.0918). Heterogeneity was high for TVS and moderate for SCSH. On subanalysis according to menopausal status, SCSH was found to have higher diagnostic accuracy in both pre- and postmenopausal women; sensitivity and specificity did not differ significantly between the groups for either TVS or SCSH. CONCLUSION Given that SCSH has better diagnostic positive and negative likelihood ratios than does TVS in both pre- and postmenopausal women, those with clinical suspicion of endometrial polyps should undergo SCSH if TVS findings are inconclusive. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

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. Wideochir Inne Tech Maloinwazyjne 2020; 15:403-415. [PMID: 32904526 PMCID: PMC7457193 DOI: 10.5114/wiitm.2020.93791] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Accepted: 02/23/2020] [Indexed: 11/18/2022] Open
Abstract
Introduction 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. Aim To evaluate and compare the diagnostic accuracy of saline infusion sonohysterography, transvaginal sonography, and hysteroscopy in detecting endometrial polyps in women with AUB. Material and methods 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. Results 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. Conclusions 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.

Abstract
Transvaginal ultrasound (TVUS) is the initial investigation of choice for postmenopausal bleeding (PMB), followed by diagnostic hysteroscopy and endometrial sampling if abnormalities are detected. Saline contrast sonohysterography (SCSH) - injection of saline through the cervix into the uterine cavity prior to TVUS - allowed increased diagnostic accuracy in women with PMB in several small, heterogeneous studies. The objectives of the current study were to evaluate the diagnostic accuracy of SCSH in women with PMB, comparing findings with surgical and pathological reports, highlight the necessity of SCSH in guiding clinical decision-making, and establish if there is an increase/decrease in the number of hysteroscopies performed for PMB and, hence, the adherence of clinicians to imaging referral guidelines. The search strategy included formulating search terms identifying all synonyms of SCSH and postmenopause. The databases searched were MEDLINE, Embase, and the Cochrane Library. Only studies comparing SCSH to an alternative method were selected. The studies were screened and data analysis performed using content analysis. Data reduction was performed through systematic coding and the generation of themes We identified 18 studies, comprising 974 women, using SCSH to evaluate the endometrial cavity in women with PMB; most support SCSH improving diagnostic accuracy through delineating intracavitary structures. In effect, SCSH could be a first-line investigative modality to assess the uterine cavity once a larger, well-designed study has been conducted to clarify its specificity, sensitivity, and positive predictive value (PPV). Owing to its relatively non-invasive nature and potentially high diagnostic accuracy, SCSH could allow for more accurate decisions regarding the need for further investigation and subsequent management.

Abstract
Introduction Different diagnostic tools are available to evaluate endometrial focal lesion such as hysteroscopy, sonohystrography and transvaginal ultrasound. The present study aimed to determine the diagnostic value of saline infusion sonohystrography (SIS) in diagnosis of intrauterine lesions in women with Abnormal Uterine Bleeding (AUB). Methods This cross-sectional study recruited 100 married women with chief complain of AUB referred to gynecologic clinics at the Amir Al-Momenin hospital, Semnan, Iran from March 2014 to February 2016. All participants were in the reproductive age and post-menopausal period that showed abnormal endometrial thickness or endometrial focal lesions through transvaginal ultrasound. Participants underwent SIS, hysteroscopy plus focal lesion resection and endometrial biopsy in order. The gold standard was the histopathology of endometrial specimen reported by pathologist. Results Mean±SD age of women was 41.2±11.3 years. To diagnose the overall focal lesions, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the SIS were 79.6, 89.1, 89.6, and 78.8% respectively. These figures were 75.0, 87.5, 82.5 and 81.7%, respectively to diagnose polyps. The SIS sensitivity, specificity, PPV and NPV values to diagnose the myomas were 60.0, 97.8, 75.0, and 95.7% respectively. Conclusion Findings show that, SIS probably is a proper method for detecting endometrial focal lesion including polyps and myomas. Future studies may help to define further advantages of this procedure.

Abstract
The rapid evolution in ambulatory hysteroscopy (AH) has transformed the approach to diagnose and manage abnormal uterine bleeding (AUB). The medical management in primary care remains the mainstay for initial treatment of this common presentation; however, many women are referred to secondary care for further evaluation. To confirm the diagnosis of suspected intrauterine pathology, the traditional diagnostic tool of day case hysteroscopy and dilatation and curettage in a hospital setting under general anesthesia is now no longer required. The combination of ultrasound diagnostics and modern AH now allows thorough evaluation of uterine cavity in an outpatient setting. Advent of miniature hysteroscopic operative systems has revolutionized the ways in which clinicians can not only diagnose but also treat menstrual disorders such as heavy menstrual bleeding, intermenstrual bleeding and postmenopausal bleeding in most women predominantly in a one-stop clinic. This review discussed the approach to manage women presenting with AUB with a focus on the role of AH in the diagnosis and treatment of this common condition in an outpatient setting.

Abstract
BACKGROUND Endometrial biopsies are undertaken in premenopausal women with abnormal uterine bleeding but the risk of endometrial cancer or atypical hyperplasia is unclear. OBJECTIVES To conduct a systematic literature review to establish the risk of endometrial cancer and atypical hyperplasia in premenopausal women with abnormal uterine bleeding. SEARCH STRATEGY Search of PubMed, Embase and the Cochrane Library from database inception to August 2015. SELECTION CRITERIA Studies reporting rates of endometrial cancer and/or atypical hyperplasia in women with premenopausal abnormal uterine bleeding. DATA COLLECTION AND ANALYSIS Data were independently extracted by two reviewers and cross-checked. For each outcome, the risk and a 95% CI were estimated using logistic regression with robust standard errors to account for clustering by study. MAIN RESULTS Sixty-five articles contributed to the analysis. Risk of endometrial cancer was 0.33% (95% CI 0.23-0.48%, n = 29 059; 97 cases) and risk of endometrial cancer or atypical hyperplasia was 1.31% (95% CI 0.96-1.80, n = 15 772; 207 cases). Risk of endometrial cancer was lower in women with heavy menstrual bleeding (HMB) (0.11%, 95% CI 0.04-0.32%, n = 8352; 9 cases) compared with inter-menstrual bleeding (IMB) (0.52%, 95% CI 0.23-1.16%, n = 3109; 14 cases). Of five studies reporting the rate of atypical hyperplasia in women with HMB, none identified any cases. CONCLUSIONS The risk of endometrial cancer or atypical hyperplasia in premenopausal women with abnormal uterine bleeding is low. Premenopausal women with abnormal uterine bleeding should first undergo conventional medical management. Where this fails, the presence of IMB and older age may be indicators for further investigation. Further research into the risks associated with age and the cumulative risk of co-morbidities is needed. TWEETABLE ABSTRACT Contrary to practice, premenopausal women with heavy periods or inter-menstrual bleeding rarely require biopsy.

Abstract
OBJECTIVE To evaluate the accuracy of transvaginal sonography (TVS) and saline infusion sonohysterography (SIS) for detection of uterine cavity abnormalities in patients with abnormal uterine bleeding (AUB) taking hysteroscopy as the gold standard. METHODS This was a prospective study done in the department of Obstetrics and Gynecology of a tertiary care academic hospital. Sixty premenopausal and postmenopausal women who presented with AUB underwent TVS, SIS, and hysteroscopy. The presence of focal abnormality and the type of abnormality, i.e., polyp, submucous myoma, and endometrial hyperplasia, were noted. The results of TVS and SIS were compared with hysteroscopy. RESULTS On hysteroscopy, 76.67 % (n = 46) patients were diagnosed with intra cavity abnormalities. SIS showed sensitivity, specificity, PPV, and NPV of 89.1, 100, 100, and 73.7 %, respectively. In comparison, TVS showed sensitivity, specificity, PPV, and NPV of 43.48, 78.57, 86.96, and 29.73 %, respectively. CONCLUSIONS SIS was found to be more sensitive and specific than TVS in detection of intra cavity abnormalities.

Abstract
STUDY OBJECTIVE To compare 2-dimensional (2D) sonohysterography (SHG) and 3D-SHG with saline solution infusion vs diagnostic hysteroscopy for investigation of intrauterine lesions in perimenopausal and postmenopausal women with abnormal uterine bleeding. DESIGN Comparative observational cross-sectional study (Canadian Task Force classification II-1). SETTING University hospital. PATIENTS Fifty perimenopausal and 20 postmenopausal women with abnormal intrauterine bleeding with clinically or ultrasonically suspected intrauterine lesions. INTERVENTIONS Conventional 2D- and 3D ultrasonography and 2D- and 3D-SHG with saline solution infusion followed by diagnostic hysteroscopy, and endometrial curettage or subsequent operative treatment (e.g., hysterectomy, myomectomy, or polypectomy). Ultrasonographic and hysteroscopic findings were compared with histopathologic findings. MEASUREMENTS AND MAIN RESULTS For 2D-SHG, sensitivity, specificity, positive predictive value, negative predictive value, overall accuracy, likelihood ratio for a positive result, and likelihood ratio for a negative result were 79%, 72%, 89%, 54%, 76%, 2.82, and 0.29, respectively, and for 3D-SHG, were 92%, 89%, 96%, 80%, 91%, 8.36, and 0.09, respectively; and for diagnostic hysteroscopy, were 94%, 89%, 96%, 84%, 93%, 8.55, and 0.07, respectively. Thus, 3D-SHG was superior to 2D SHG (p = .02) and comparable to diagnostic hysteroscopy (p = .75) for diagnosis of intrauterine lesions. CONCLUSION 3D-SHG can be used in the initial investigation of intrauterine lesions in perimenopausal and postmenopausal women with abnormal uterine bleeding before resorting to invasive procedures such as diagnostic hysteroscopy. Further studies of computer-reconstructed 3D-SHG virtual hysteroscopy are recommended.

Abstract
INTRODUCTION To compare the diagnostic values of three-dimensional sonohysterography (3DSH), transvaginal ultrasound (TVUS), and 2-dimensional sonohysterography (2DSH) in the work-up of abnormal uterine bleeding (AUB), in particular the ability of each method to identify intracavitary lesions arising from the endometrium or uterine wall. MATERIALS AND METHODS 24 patients referred for AUB underwent TVUS followed by 2-D and 3-D HS in the same session. Three-dimensional data were acquired with a free-hand technique during maximal distention of the uterus. Within 10 days of the sonographic session, each patient underwent hysteroscopy, which was considered the reference standard. For each of the 3 imaging methods, we calculated sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. RESULTS Hysteroscopy demonstrated the presence of an intrauterine lesion in 21/24 patients (87.5%). In 3/24 patients hysteroscopy was negative. For TVUS, 2DSH, and 3DSH, sensitivity was 76% (16/21), 90% (19/21), 100% (21/21), respectively; specificity was 100% (3/3), 100% (19/19), 100% (21/21); PPV was 100%, 100%, 100%; NPV was 37%, 60%, 100%; accuracy was 76%, 90%, 100%. CONCLUSIONS 3DSH is more sensitive that 2DSH or TVUS in the detection of intrauterine lesions. If these preliminary results are confirmed in larger studies, 3DSH could be proposed as a valuable alternative to diagnostic hysteroscopy.
