Diagnostic value of sonohysterography in the evaluation of submucosal fibroids and endometrial polyps

Endometrial polyps. An evidence-based diagnosis and management guide

OBJECTIVE

To provide an updated practice guideline for the management of patients with endometrial polyps.

MATERIALS AND METHODS

A committee of six expert researchers draw the recommendations according to AGREE II Reporting Guideline. An electronic search was performed querying the following databases MEDLINE (accessed through PubMed), Scopus, PROSPERO, EMBASE, CINAHL, Cochrane Library (including the Cochrane Database of Systematic Reviews), Scielo.br, Google Scholar, from inception to May 2020. A combination of text-words and Medical Subject Headings (MeSH) regarding endometrial polyps, diagnosis, management and treatment was used. Trials were assessed for methodologic rigor and graded using the United States Preventive Services Task Force classification system.

RECOMMENDATIONS

Transvaginal ultrasonography (TVUS) should be the imaging modality of choice for the detection of endometrial polyps in woman of fertile age (level B). Its accuracy increases when color-doppler, 3D investigation and contrast are used (level B). Dilation and Curettage (D&C) should be avoided for the diagnosis and management of polyps (level A). In office hysteroscopy showed the highest diagnostic accuracy in infertile patients with suspected endometrial polyps (level B). Polyps might alter endometrial receptivity, and embryo implantation reducing pregnancy rates (level C). Hysteroscopic polypectomy is feasible and safe with negligeble risk of intrauterine adhesion formation (level B). Polypectomy does not compromise reproductive outcomes from subsequent IVF procedures but the removal of polyps as a routine practice in sub-fertile women is not currently supported by the evidence (level B). Cost-effectiveness analysis suggest performing office polypectomy in women desiring to conceive (level B). Saline infused sonohysterography is highly accurate in detecting polyps in asymptomatic postmenopausal women (level B). Postmenopausal women with vaginal bleeding and suspected endometrial polyp should be offered diagnostic hysteroscopy with hysteroscopic polypectomy if endometrial polyps are present (level B). In-office hysteroscopy has the highest diagnostic accuracy with high cost-benefits ratio for premalignant and malignant pathologies of the uterine cavity (level B). Due to risk of malignancy, histopathological analysis of the polyp is mandatory (level B). Blind D&C should be avoided due to inaccuracy for the diagnosis of focal endometrial pathology (level A). Expectant management is not recommended in symptomatic patients especially in postmenopausal women (level B). In case of atypical hyperplasia or carcinoma on a polyp, hysterectomy is recommended in all post-menopausal patients and in premenopausal patients without desire of future fertility (level B). Asymptomatic endometrial polyps in postmenopausal women should be removed in case of large diameter (> 2 cm) or in patients with risk factors for endometrial carcinoma (level B). Excision of polyps smaller than 2 cm in asymptomatic postmenopausal patients has no impact on cost-effectiveness or survival (level B). Removal of asymptomatic polyps in premenopausal women should be considered in patients with risk factors for endometrial cancer (level B).

Unravelling the endometrium: a pictorial review of saline infusion sonohysterography in the evaluation of abnormal uterine bleeding

This article describes the diagnosis of causes of abnormal uterine bleeding with experience of the biggest medical institute in Kashmir, India. We work in a low resource setting where unavailabity of hysteroscopy made us acknowledge the accuracy and efficacy of saline infusion sonohysterography in diagnosis of patients with AUB thus helping guide their management.

Role of 3-Dimensional Sonography in the Assessment of Submucous Fibroids: A Pilot Study

OBJECTIVES

To investigate the accuracy and reliability of 3-dimensional (3D) transvaginal sonography in classifying submucous fibroids using the International Federation of Gynecology and Obstetrics PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified) classification and protrusion (percent) compared to 2-dimensional (2D) transvaginal sonography, 2D saline infusion sonography, and 3D saline infusion sonography, using hysteroscopy as a reference test.

METHODS

A prospective cohort pilot study was performed among 14 consecutive patients undergoing hysteroscopic surgery, preceded by routine sonography (2D transvaginal sonography, 2D saline infusion sonography, 3D transvaginal sonography, and 3D saline infusion sonography).

RESULTS

The intraclass correlation coefficient (ICC) for 2D transvaginal sonography versus hysteroscopy was 0.69 (95% confidence interval [CI], 0.06, 0.90) compared to 0.94 (95% CI, 0.83, 0.98) for 2D saline infusion sonography. The ICCs for 3D transvaginal sonography versus hysteroscopy were 0.69 (95% CI, 0.03, 0.90 [investigator A]) and 0.55 (95% CI, -0.48, 0.86 [investigator B]). The ICCs for 3D saline infusion sonography versus hysteroscopy were 0.94 (95% CI, 0.81, 0.98 [investigator A]) and 0.87 (95% CI, 0.60, 0.96 [investigator B]). Interobserver agreement of 3D transvaginal sonography was 0.81 (95% CI, 0.43, 0.94) compared to 0.86 (95% CI, 0.56, 0.96) for 3D saline infusion sonography.

CONCLUSIONS

In these preliminary data, 3D transvaginal sonography was not as accurate as 2D or 3D saline infusion sonography and was not more accurate than 2D transvaginal sonography. There was moderate interobserver agreement for 3D transvaginal sonography. There might be room for improvement, as 3D transvaginal sonography is more accurate when endometrial thickness increases. Further study is warranted to evaluate in which patients saline infusion sonography eventually can be obviated.

[Role of hydrosonography in prevention and screening of premalignant and malignant endometrial disease]

INTRODUCTION

The study emphasizes the significance of hydrosonography in prevention and early diagnostics of endometrial pathology.

OBJECTIVE

To express the significance of hydrosonography in relation to timely detection and treatment of premalignant and malignant endometrial disease.

METHOD

Our study included 104 patients referred to transvaginal sonography, after which hydrosonography was recommended in order to obtain precise visualization of the endometrium because of suspected endometrial pathology. After hydrosonography, dilatation and curettage with endometrial biopsy were performed in all patients. Biopsy specimens were histologically analyzed.

RESULTS

The application of contrast sonography described in our research helped diagnose and timely treat as many as 30.8% of patients suffering from premalignant and malignant endometrial disease (23.2% of premalignant and 7.6% of malignant). Discomforts (bleeding and pelvic pain) occurred in 72.1% of patients, out of whom 43.3% had already undergone curettage once or more than once because of the same or similar symptoms, while 27.9% of cases presented for regular control, i.e. they were symptom free. The obtained results clearly emphasized the significance of application of contrast sonohysterography as a method for timely detection of endometrial pathology and its adequate treatment.

CONCLUSION

The study shows that application of contrast sonohysterography before exploratory curettage significantly facilitates the use of invasive diagnostics and improves accuracy and validity of the obtained results, especially in cases of endometrial focal changes; consequently, it is also possible to achieve positive cost-benefit effect.

Comparison of hysterosalpingography, hysterosonography and hysteroscopy in evaluation of the uterine cavity in patients with recurrent pregnancy losses

AIM

To evaluate the accuracy and acceptability of hysterosonography (HS) in the diagnosis of uterine anomalies in patients with recurrent pregnancy loss.

METHOD

Sixty non-pregnant patients with a history of at least three previous recurrent miscarriages were submitted to the HS, HSG and hysteroscopy (HTC) exams. The findings fall into three categories: synechiae, polypoid lesions and abnormal uterine cavity shape. The HTC exam was used as the gold standard. The findings of the HS and the HSG were compared to the HTC's and the agreement was evaluated using the Kappa coefficient. Significance was established at < 0.05. Sensitivity, specificity, positive and negative predictive values were determined for each method.

RESULT

Uterine anomalies were present in 38.3% (23) of the patients: 16 (26.7%) with synechiae, 3 (5.0%) with polypoid lesions and 8 (13.3%) with abnormal uterine cavity shape. Accuracy of the HS and the HSG was 90.9 and 85.2%. General sensitivity of the HS was superior to the HSG (90.5 vs. 75.0%). It also had a higher degree of agreement with the HTC (Kappa = 0.81 vs. 0.68). The HS caused significantly less pain than the other two methods.

CONCLUSIONS

The HS had higher diagnostic accuracy in the detection of uterine cavity anomalies and it was better tolerated by the patients when compared to hysterosalpingography and hysteroscopy.

Recurrent implantation failure in assisted reproduction: how to counsel and manage. A. General considerations and treatment options that may benefit the couple

Recurrent implantation failure is a distressing phenomenon, both for the infertile couple and for the physician responsible for their treatment. Aetiology is often not clear and treatment options are vague. Particularly when transferred embryos are of good quality, recurrent implantation failure may be attributed to less than optimal embryo transfer technique, pathological lesions of the uterine cavity, the presence of hydrosalpinges, fibroids and endometriosis. Poor embryo quality, especially when repetitive, is a major impediment to successful implantation and cannot be corrected at the present time. Molecular abnormalities at the endometrial level and abnormal embryo-endometrium dialogue may be responsible for some cases of recurrent implantation failure. Furthermore, there may be over- or under-expressed genes that may be related to successful implantation. At the present time, the physician confronted with a couple presenting with recurrent implantation failure should discuss openly the potential causes of this phenomenon, with special emphasis on correctable causes, and offer remedies that are evidence based.
