Haimovich S, Tanvir T. A Mini-Review of Office Hysteroscopic Techniques for Endometrial Tissue Sampling in Postmenopausal Bleeding. J Midlife Health 2021; 12:21-29.

Abstract
Postmenopausal bleeding (PMB) is a common cause for a gynecological visit. Endometrial cancer risk varies from 3% to 25% in women with PMB. There is a significant concern of malignancy of the endometrium and the endocervical canal by a physician in postmenopausal women, and hence, most prefer operating room hysteroscopies with dilation and curettage (D & C) compared to in-office procedures. With increased availablility of miniaturized instruments such as mini- resectoscope and tissue removal systems, there is high likelihood of blind D & C being replaced by hysteroscopic- guided targetted biopsy or visual D & C. The cost-effectiveness of office hysteroscopy is also well demonstrated. In December 2020, an electronic search was performed of PubMed, MEDLINE, and Cochrane Library to look for articles on office hysteroscopic biopsy techniques in postmenopausal women from 2010 to 2020. Relevant studies were included where various office hysteroscopic techniques are used for endometrial sampling in PMB. Studies with 5 Fr scissors, biopsy forceps, crocodile forceps, cup forceps, bipolar electrode, in-office tissue removal system (morcellator), flexible hysteroscope, and mini-resectoscope were included. Standard reference was used as an adequate endometrial sample for histology. The objective of this review is to explore the current evidence on different office hysteroscopic techniques available for endometrial tissue sampling in PMB.

The thin red line - postmenopausal abnormal uterine bleeding with endometrial thickness less than 4 mm. Contemp Oncol (Pozn) 2019; 23:43-46. [PMID: 31061636 PMCID: PMC6500390 DOI: 10.5114/wo.2019.83816] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Accepted: 01/31/2019] [Indexed: 11/17/2022] Open
Abstract
Aim of the study To evaluate the risk of endometrial malignancy in postmenopausal women with abnormal uterine bleeding (AUB) with endometrial thickness ≤ 4 mm. Material and methods Histological assessment of endometrial samples obtained via hysteroscopy or curettage was performed in 57 women. Results Women with premalignancy or malignancy (24.6%) had higher endometrial thickness (by 9.7%, p = 0.01) compared to women with benign condition. Out of 12 women with atypical hyperplasia (21.1%), 5 women (8.8%) were diagnosed with simple and 7 women (12.3%) had complex hyperplasia, whereas 2 (3.5%) were diagnosed with malignancy. Conclusions Postmenopausal women with AUB and endometrial echo ≤ 4 mm are less likely to have a malignant condition. However, the role of histological evaluation cannot be undermined, especially in women at high risk of endometrial cancer, and routine endometrial biopsy should be considered. We recommend a change in the cut-off to 2 mm in routine practice.

Abstract
Background Even in the face of a substantial increase in the numbers of endometrial cancer cases and in the numbers of women who have risk factors, there is no clear agreement about the indications for assessing the endometria of women with abnormal bleeding or about the tools to use in that assessment. This study sought to determine in a group of high risk women with abnormal uterine bleeding, the probability that an outpatient endometrial aspiration would identify significant pathology. Methods Retrospective cohort study of the histology from endometrial aspirations performed from 2001 to 2008 for abnormal uterine bleeding at Harbor-UCLA Medical Center and its satellite public health clinics. Medical records were reviewed in detail to assess risk factors, descriptions of bleeding abnormalities and histologic results. Results The charts of 1601 women who underwent 1636 endometrial biopsies for a wide variety of abnormal uterine bleeding patterns yielded 73 (4.6 %) cases of endometrial carcinoma, 43 cases of atypical endometrial hyperplasia (2.7 %), for an overall yield of significant pathology of 7.2 %. Hyperplasia without atypia was found in another 83 cases (5.2 %). Obesity, diabetes and postmenopausal age are associated with an increased risk of significant pathology. Bleeding patterns were so poorly documented that analysis of yield by this factor should be viewed with caution. Conclusions The probability of detecting significant uterine pathology is greatest among obese, diabetic postmenopausal women with diabetes (26.3 %). Conversely, the probability of identifying significant pathology in younger women without risk factors is less than 2 %. For women who perceive their individualized risk estimate to be too small to justify an endometrial biopsy, it may be possible to offer oral higher dose progestin therapy on the condition that persistent abnormal bleeding will require more intensive evaluation. These estimates of absolute risk of being diagnosed with significant pathology on endometrial biopsy may be helpful to patients as they consider giving informed consent for the procedure.

Abstract
OBJECTIVE To determine the preoperative pelvic ultrasonographic characteristics of postmenopausal women diagnosed with endometrial cancer (EC) at our institution. METHODS Postmenopausal women with EC who underwent preoperative transvaginal pelvic ultrasound from 1999-2009 were identified from our institutional database. The histologic diagnosis was based on pathologic findings in the hysterectomy specimen. Endometrial echo complex (EEC) thickness was abstracted from ultrasound reports. In all instances, ultrasound preceded the biopsy by a maximum of 3 months. Means with standard deviations were calculated for all categorical data. Differences between type 1 and type 2 ECs were determined using Mann-Whitney U tests and Chi squared/Fisher's exact tests, as appropriate. A p-value of <0.05 was considered statistically significant. RESULTS Among 250 patients with postmenopausal EC, 156 had type 1 EC while 94 had type 2 EC. Thirty-six percent of the cohort had an EEC ≤ 4 mm, including 37% of patients with type 1 EC and 34% of patients with type 2 EC (p=0.63). There were no significant differences between type 1 and type 2 ECs in any demographic characteristic, other than likelihood of postmenopausal bleeding. CONCLUSIONS Current expert opinion recommends no further diagnostic procedure in a woman with postmenopausal bleeding and an EEC ≤ 4 mm. These results indicate that a sizable proportion of women with EC have EECs ≤ 4 mm during their initial evaluation. An EEC ≤ 4 mm does not completely rule out endometrial cancer and cannot supplant histologic evaluation.

Abstract
In the United States, endometrial cancer is the most commonly diagnosed cancer of the female reproductive system. Strategies to sensitively and accurately diagnose premalignant endometrial lesions are sorely needed. We reviewed studies pertaining to the diagnostic challenges of endometrial precancers, their predictive value, and evidence to support management strategies. Currently, two diagnostic schemas are in use: the four-class 1994 World Health Organization hyperplasia system, based on morphologic features of architectural complexity and nuclear atypia and, more recently, the two-class endometrial intraepithelial neoplasia system, which is quantitative. Diagnosis should use criteria and terminology that distinguish between clinicopathologic entities that can be managed differently. In some instances, such as for women with hereditary nonpolyposis colon cancer, biomarkers may aid in diagnosis, but the clinical utility of biomarkers has yet to be determined. Total hysterectomy is curative for atypical endometrial hyperplasia or endometrial intraepithelial neoplasia, and provides a definitive standard for assessment of a concurrent carcinoma, when clinically appropriate. If hysterectomy is performed for atypical endometrial hyperplasia or endometrial intraepithelial neoplasia, then intraoperative assessment of the uterine specimen for occult carcinoma is desirable, but optional. Nonsurgical management may be appropriate for patients who wish to preserve fertility or those for whom surgery is not a viable option. Treatment with progestin therapy may provide a safe alternative to hysterectomy; however, clinical trials of hormonal therapies for atypical endometrial hyperplasia or endometrial intraepithelial neoplasia have not yet established a standard regimen. Future studies will need to determine the optimal nonsurgical management of atypical endometrial hyperplasia or endometrial intraepithelial neoplasia, standardizing agent, dose, schedule, clinical outcomes, and appropriate follow-up.

Abstract
IntroductionThe aim of this study was to develop a multivariable model to predict the risk of endometrial carcinoma in postmenopausal women with vaginal bleeding using individuals' clinical characteristics.Patients and MethodsThis prospective study of consecutive postmenopausal women presenting with vaginal bleeding was conducted at a gynecological oncology center in the United Kingdom for a 46-month period. All women underwent transvaginal ultrasound scanning as the initial investigation tool to evaluate the endometrium. Women found to have an endometrial thickness 5 mm or more had endometrial sampling performed.ResultsOf a total of 3548 women presenting with vaginal bleeding during the study period, 201 (6%) women had a diagnosis of endometrial carcinoma. An investigator-led best model selection approach used to select the best predictors of cancer in the multiple logistic regression model showed that patient's age (odds ratio [OR], 1.06), body mass index (OR, 1.07), recurrent episodes of bleeding (OR, 3.64), and a history of diabetes (OR, 1.48) increased the risk of endometrial malignancy when corrected for other characteristics. The mentioned clinical variables satisfied the criteria for inclusion in our predictive model called FAD 31 (F for the frequency of bleeding episodes, A for the age of the patient, D for diabetes, and the number 31 represents the BMI cut-off value). The total score for the model varies from 0 to 8. The area under the receiver operating characteristics curve for the developed model was 0.73 (95% confidence interval, 0.70-0.77).DiscussionWe have developed a simple model based on patients' clinical characteristics in estimating the risk of endometrial cancer for postmenopausal women presenting with vaginal bleeding. The model shows reasonable discriminatory ability for women with cancer and without, with an area under the receiver operating characteristics curve of 0.73. This will allow clinicians to individualize the diagnostic pathway for women with postmenopausal vaginal bleeding.

Abstract
OBJECTIVE To estimate the accuracy of endometrial thickness measurement in the detection of endometrial cancer among women with postmenopausal bleeding with individual patient data using different meta-analytic strategies. DATA SOURCES Original data sets of studies detected after reviewing the included studies of three previous reviews on this subject. An additional literature search of published articles using MEDLINE databases was preformed from January 2000 to December 2006 to identify articles reporting on endometrial carcinoma and sonographic endometrial thickness measurement in women with postmenopausal bleeding. METHODS OF STUDY SELECTION We identified 90 studies reporting on endometrial thickness measurements and endometrial carcinoma in women with postmenopausal bleeding. TABULATION, INTEGRATION, AND RESULTS We contacted 79 primary investigators to obtain the individual patient data of their reported studies, of which 13 could provide data. Data on 2,896 patients, of which 259 had carcinoma, were included. Several approaches were used in the analyses of the acquired data. First, we performed receiver operator characteristics (ROC) analysis per study, resulting in a summary area under the ROC curve (AUC) calculated as a weighted mean of AUCs from original studies. Second, individual patient data were pooled and analyzed with ROC analyses irrespective of study with standardization of distributional differences across studies using multiples of the median and by random effects logistic regression. Finally, we also used a two-stage procedure, calculating sensitivities and specificities for each study and using the bivariate random effects model to estimate summary estimates for diagnostic accuracy. This resulted in rather comparable ROC curves with AUCs varying between 0.82 and 0.84 and summary estimates for sensitivity and specificity located along these curves. These curves indicated a lower AUC than previously reported meta-analyses using conventional techniques. CONCLUSION Previous meta-analyses on endometrial thickness measurement probably have overestimated its diagnostic accuracy in the detection of endometrial carcinoma. We advise the use of cutoff level of 3 mm for exclusion of endometrial carcinoma in women with postmenopausal bleeding.

Abstract
Endometrial sampling using the Pipelle device is widely used in the UK especially in the investigation of postmenopausal bleeding. This study was aimed at evaluating the clinical benefit and diagnostic accuracy of the procedure in the setting of a dedicated one-stop clinic for women with postmenopausal bleeding. The study also examined the factors that would affect the adequacy of endometrial samples in terms of their suitability for histopathalogical examination. Data from 97 consecutive patients attending the clinic were collected and analysed. All the patients had a transvaginal ultrasound scan and an endometrial Pipelle sample was attempted unless refused by the patient. The analysis revealed that the procedure avoided the need for hysteroscopy in 61.5% of cases with an endometrial thickness of > 4mm. No cases of endometrial cancer were missed after successful Pipelle sampling. The ability to obtain an adequate endometrial sample was primarily affected by the endometrial thickness. There is only a 27% probability of getting an adequate endometrial sample in the group of women with an endometrial thickness of < 5 mm. The study recommends this procedure for the group of women with an endometrial thickness of > 4 mm. However, when the endometrial thickness is < or = 4 mm, little can be gained from endometrial sampling as malignancy is rare and the chance of getting an adequate sample is small.

Abstract
All postmenopausal women with vaginal bleeding need endometrial assessment. Disposable suction piston biopsy devices have virtually replaced dilatation and curettage despite little scientific validation. In patients with known carcinoma, false-negative rates with such devices range from 2.5-32.4%. Large prospective studies have shown that an endometrial thickness <or= 4 mm on transvaginal ultrasound in postmenopausal women with bleeding has a risk of malignancy of 1 in 917. Thus, in postmenopausal patients with bleeding, biopsy is not indicted when endometrial thickness is <or= 4 mm. The significance of a thick endometrial echo in nonbleeding postmenopausal women has not been validated and need not require automatic tissue sampling.

Abstract
OBJECTIVE Endometrial cancer is the most common gynecologic malignancy. The cornerstone of treatment remains surgery according to International Federation of Gynecology and Obstetrics staging. The aim of this study was to evaluate the concordance between myometrial infiltration detected by ultrasonography and gross examination with respect to definitive histologic examination and to select a population in which lymphadenectomy could be excluded. We also evaluated the concordance for the degree of tumor differentiation between diagnostic biopsy and final histologic results. METHODS Our study included 75 patients with International Federation of Gynecology and Obstetrics stage I endometrial cancer. We evaluated preoperative and definitive grading and myometrial infiltration detected by ultrasonography and gross examination. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of the procedures under study were determined with the Bayes theorem. To determine the predictive value of preoperative transvaginal ultrasonography and intraoperative gross examination for myometrial invasion, we used a multiple logistic regression model with a statistical software package. RESULTS Our study showed 60% concordance between biopsy and histologic results. In 80% of the cases with discordant results, the tumor was undergraded. Ultrasonography had diagnostic accuracy of 73%, whereas gross examination correctly determined myometrial invasion in 82.6% of the patients, with sensitivity of 62% and specificity of 79%. CONCLUSIONS Preoperative transvaginal ultrasonography and macroscopic gross examination appear to be simple, fast, and reliable methods to predict in myometrial invasion in patients with a low risk for lymph node metastasis, for which lymphadenectomy can reasonably be avoided.

Abstract
OBJECTIVE To evaluate the clinical and sonographic features in patients with endometrial malignancy in whom endometrial thickness on ultrasound examination had been recorded in our database to be < 5 mm. METHODS This was a retrospective observational study on 187 consecutive patients diagnosed with endometrial malignancy in whom an ultrasound evaluation of the endometrium had been performed in our institution. The characteristics of those patients presenting with an endometrial thickness < 5 mm were analyzed. RESULTS The median endometrial thickness was 15 mm: 12 mm for the women who underwent endometrial sampling before ultrasound examination vs. 17 mm in those who did not (P = 0.0086). In 13 women (6.9%), the endometrial thickness recorded in our database was < 5 mm. In 12 of these the measurement was compromised in some way: nine of these patients had undergone endometrial sampling (Pipelle biopsy in one and dilatation and curettage in eight patients) before the ultrasound examination, in two cases, focal malignant lesions were not included in the recorded endometrial thickness and in one, the endometrial thickness was visualized poorly due to myometrial distortion. In only one case was was the endometrium correctly measured to be < 5 mm; this woman had diffuse uterine and endometrial metastases of a breast cancer. CONCLUSIONS A thin and regular endometrial line is very reliable for the exclusion of endometrial carcinoma. The suspicion of focal lesions as well as incomplete visualization of the endometrium on sonography should be considered abnormal. Recently performed endometrial sampling makes measurement of the endometrial thickness unreliable.

Abstract
OBJECTIVE To evaluate if, and to what extent, Pipelle de Cornier endometrial sampling influences the ultrasonographic features of the endometrium. METHODS This was a prospective descriptive study on 99 consecutive women in whom a Pipelle endometrial biopsy was performed. All patients first underwent a transvaginal ultrasound evaluation of the uterus. The endometrial thickness (ET) was measured and endometrial sonographic features were recorded. Thereafter, a Pipelle endometrial biopsy was taken. Finally, the ultrasound examination was repeated. The patients' characteristics, the sampling procedure, the endometrial histology and the sonographic findings before and after Pipelle biopsy were compared. RESULTS Ninety-nine women, of whom 45% were postmenopausal, entered the study. The mean age was 59.0 years (SD, 9.9) for the postmenopausal women, and 41.6 years (SD, 8.7) for the rest. On histological examination, endometrial cancer was diagnosed in four patients and endometrial hyperplasia in eight patients. The average ET before Pipelle sampling was 9.0 mm (SD, 6.6) vs. 8.6 mm (SD, 7.0) after biopsy (P < 0.0001). After Pipelle sampling, the endometrium was less clearly delineated (P = 0.03) and more echogenic endometrial spots were seen (P < 0.0001). If an endometrial three-layer pattern was noted before sampling, it was not observed in most women after Pipelle biopsy (P = 0.0003). CONCLUSIONS ET measurements are affected by Pipelle sampling and the quality of the ultrasound features tends to be altered by biopsy. Performing the ultrasound examination before proceeding with endometrial sampling may therefore improve diagnostic accuracy of ultrasound.

Abstract
In western countries hormone replacement therapy (HRT) is a widely used therapeutic and/or preventive medication in post-menopausal women. Its impact on the endometrium has been extensively investigated. The critical issue is whether and how to monitor the endometrium in women who are taking HRT. Transvaginal ultrasound is a potential candidate for this role. Evidence for the efficiency of transvaginal sonography (TVS) in this context is limited. The criteria used to define a normal or abnormal result in women taking HRT are based largely on data from post-menopausal women who are not taking this treatment. This extrapolation is probably reasonable as long as some degree of caution is used. The use of normative data from post-menopausal women for those taking selective oestrogen receptor modulators (SORMs) is not advised and should be utilized only in the context of research studies as insufficient data exist on which to base cut-off values to discriminate between normal and abnormal endometria.

Abstract
Transvaginal ultrasound examination can reliably distinguish women with post-menopausal bleeding (PMB) who are at low risk of endometrial pathology (endometrial thickness < or =4 mm) from those who are at high risk (endometrium > or =5 mm) and can rule out focally growing lesions in the uterine cavity using saline infusion into the cavity as a negative contrast agent (hydrosonography). The 5 mm cut-off is applicable irrespective of the use of hormone replacement therapy. It is justified to refrain from endometrial sampling in women with PMB and an endometrial thickness of < or =4 mm because the risk of endometrial cancer in these women is low (0.1-1.0%). However, it is not known whether these women need follow-up. About 80% of women with PMB and an endometrium of > or =5 mm have focally growing pathological lesions in the uterine cavity. These should be removed by operative hysteroscopy because dilatation and curettage (D and C) will fail to diagnose and remove a large proportion of these lesions. However, D and C is a reliable diagnostic method for women without focal lesions in the uterine cavity. It is not known whether simple outpatient sampling devices (e.g. Pipelle) are as reliable as D and C in women without focal lesions. A measurement of endometrial thickness is a simple and accurate method for estimating the risk of endometrial cancer. The reliability of ultrasound evaluation of endometrial morphology and/or vascularization for risk estimation of endometrial malignancy remains to be determined.

Abstract
BACKGROUND The objective was to determine how postmenopausal bleeding (PMB) is managed in Sweden today, and to relate the findings to a new evidence-based algorithm for the management of PMB. METHODS A questionnaire regarding the role of ultrasound and the use of different endometrial biopsy methods in the management of PMB was sent to all 61 gynecologic departments in Sweden. RESULTS Fifty-nine of the 61 departments (97%) satisfactorily answered the questionnaire. Ultrasound was either always (n = 54, 92%) or most commonly (n = 5, 8%) used in the diagnostic work-up of PMB. In women with endometrial thickness < or =4 mm, 18 of the departments (31%) routinely sampled the endometrium; 12 (15%) followed the women with ultrasound; three (5%) did both sampling and follow-up with ultrasound; and the remaining 29 (49%) used expectant management (i.e. no biopsy or routine follow-up). In women with endometrium > or =5 mm, hydrosonography was performed routinely in two departments (3%), occasionally in 37 departments (63%), and never in 20 departments (34%). In women with endometrium > or =5 mm, endometrial biopsy was obtained routinely by Endorette/Pipelle in 39 departments (66%), while in 26 departments (44%) operative hysteroscopy was never performed. CONCLUSION More than one-third of the gynecologic departments in Sweden never perform hydrosonography to rule out focal lesions or operative hysteroscopy for the removal of such lesions. Hydrosonography and hysteroscopy have a central role in the new guidelines for the management of PMB. Therefore, a need exists to broaden the use of hydrosonography and hysteroscopy.

Abstract
OBJECTIVES To determine intraobserver and interobserver reproducibility of ultrasound measurements of endometrial thickness in postmenopausal women. DESIGN Forty-eight postmenopausal women underwent transvaginal ultrasound examination by two examiners. Each observer took three replicate measurements of the endometrium in each woman. Intraobserver repeatability was expressed as the difference between the highest and lowest measurement values obtained by one observer, the repeatability coefficient, and the intraclass correlation coefficient. Interobserver reproducibility was expressed as the difference between the mean of the three measurements of each observer, limits of agreement, and interclass correlation coefficient. The repeatability coefficient and the limits of agreement define the range within which 95% of the differences between two measurements are likely to fall. Data were analyzed for all women, as well as separately for women with endometrium < or = 6 mm and > 6 mm. The agreement between observers in classifying women as having endometrium < or = 4.4 mm or > or= 4.5 mm was determined by calculating Cohen's kappa. RESULTS In women with endometrium <or = 6 mm the intraclass correlation coefficient was 0.95 for Observer 1 and 0.88 for Observer 2, the median difference between the highest and lowest values being 0.4 mm (range, 0-1.4) for Observer 1 and 0.7 mm (range, 0.1-2.2) for Observer 2, and the repeatability coefficient was 0.8 mm and 1.4 mm, respectively. The corresponding figures for women with endometrium > 6 mm were 0.99 and 0.99, 0.7 mm (0-2.9) and 1.0 mm (0.2-3.4), and 1.7 mm and 1.9 mm. In women with endometrium < or = 6 mm the interclass correlation coefficient was 0.77, and the mean interobserver difference was 0.2 mm +/- 1.8 mm (2 standard deviations), when calculations were based on the mean of three measurements per observer (+/- 1.9 mm when calculations were based on only one measurement per observer). The corresponding figures for women with endometrium > 6 mm were 0.98, 0.2 mm +/- 3.1 mm (+/- 3.2 mm). The agreement between observers in classifying women as having an endometrium < or = 4.4 mm or > or = 4.5 mm was very good (kappa 0.81). CONCLUSIONS The reproducibility of endometrial measurements seems to be clinically acceptable and to allow reliable discrimination between postmenopausal women with endometrium < or = 4.4 mm and > or = 4.5 mm. In clinical practice, it is enough to take one endometrial measurement when performing transvaginal ultrasound examination.
