Hysteroscopic evaluation of menopausal patients with sonographically atrophic endometrium

STUDY OBJECTIVE: To assess the diagnostic and operative potential of hysteroscopy in postmenopausal patients selected by ultrasound criteria. DESIGN: Prospective evaluation (Canadian Task Force classification II-2). SETTING: Outpatient ultrasound and hysteroscopy department of a university-affiliated hospital. PATIENTS: Two hundred twelve women with an endometrial thickness less than 4 mm on ultrasound and in menopause for at least 1 year. INTERVENTIONS: Transvaginal ultrasound and office hysteroscopy, with eye-directed biopsy specimens obtained with a 5-mm, continuous-flow operative hysteroscope, and performed without anesthesia. MEASUREMENTS AND MAIN RESULTS: Only 13 (6%) patients were symptomatic (irregular bleeding). Hysteroscopic diagnosis of endometrial polyps in three women (23%) was confirmed by histology. In the remaining 199 (94%) asymptomatic patients with atrophic endometrium on ultrasound, hysteroscopy showed an endometrial pathology in 10% (16 polyps, 4 submucous myomas); in one patient histologic evaluation disclosed focal adenocarcinoma in an endometrial polyp. CONCLUSION: Hysteroscopy allows a proper histologic diagnosis, even in asymptomatic postmenopausal women with atrophic endometrium on ultrasound.     

Direct aspiration endometrial biopsy via flexible hysteroscopy

Study ObjectiveTo determine feasibility and efficacy of direct aspiration endometrial biopsy via the fluid channel of a flexible diagnostic hysteroscope.DesignRetrospective review (Canadian Task Force classification II-3).SettingAbnormal uterine bleeding clinic in a tertiary care center.PatientsAll women who underwent direct aspiration endometrial biopsy from January 2007 through August 2011 via a flexible diagnostic hysteroscope because traditional office-based endometrial biopsy using a suction piston device was not technically possible.InterventionsDiagnostic hysteroscopy followed by direct aspiration endometrial biopsy, accomplished by applying suction to the fluid channel of a 3.1-mm flexible diagnostic hysteroscope via a 10-mL syringe. The hysteroscope tip was agitated within the uterine cavity to obtain a tissue sample.Measurements and Main ResultsThe median age of the 32 identified patients was 50 years; 18 women (56%) were nulliparous, and 10 (31%) were postmenopausal. Thirty-one patients underwent hysteroscopy/direct aspiration biopsy because of abnormal uterine bleeding or postmenopausal bleeding. The vaginoscopic approach was used in 19 patients (59%). Indications for direct aspiration endometrial biopsy included cervical stenosis, inability to pass the endometrial biopsy instrument into the uterine cavity, and patient intolerance of endometrial biopsy. Adequate endometrial samples were obtained in 28 patients (87.5%). In 3 of 4 patients in whom direct aspiration endometrial biopsy did not provide sufficient tissue, hysteroscopy revealed an atrophic-appearing endometrium. The direct aspiration endometrial biopsy diagnosis was confirmed in 5 of 7 patients who subsequently underwent dilation and curettage or hysterectomy.ConclusionDirect aspiration endometrial biopsy is a simple and effective endometrial sampling method when traditional office-based endometrial biopsy is not feasible. Further prospective studies including larger populations are needed to confirm these results.

Detection of benign intracavitary lesions in postmenopausal women with abnormal uterine bleeding: a prospective comparative study on outpatient hysteroscopy and blind biopsy

STUDY OBJECTIVE: To evaluate the specificity of blind biopsy in detecting benign intracavitary lesions as causes of postmenopausal bleeding in comparison with directed biopsy via hysteroscopy. DESIGN: Prospective trial without randomization (Canadian Task Force classification II-1). SETTING: University hospital. PATIENTS: Three hundred nineteen postmenopausal women with abnormal uterine bleeding. INTERVENTIONS: All patients underwent both blind biopsy (Novak's curette) and directed biopsy via hysteroscopy (after at least a week). All patients with benign intracavitary lesions underwent operative hysteroscopy to enable the removal of polyps and intracavitary myomas or endometrial resection if required. All patients with pathologic reports of complex hyperplasia and atypical hyperplasia (20 patients) underwent vaginal hysterectomy with bilateral adnexectomy. All patients with histology reports of endometrial carcinoma (15 patients) underwent abdominal hysterectomy, bilateral adnexectomy, and pelvic lymphadenectomy. Histopathologic findings from endometrial specimens obtained after operative hysteroscopy or uterine specimens obtained after hysterectomy were used as a reference test to establish the prevalence of disease. MEASUREMENTS AND MAIN RESULTS: The sensitivity, specificity, accuracy, and positive and negative predictive values of blind biopsy and hysteroscopy were assessed to distinguish benign intracavitary formations such as polyps, submucous myomas, and endometrial hyperplasia in postmenopausal patients with abnormal uterine bleeding. The level of agreement was evaluated by use of the coefficient of concordance kappa. Blind biopsy showed a sensitivity of 11% and a specificity of 93%, with an accuracy of 59% in detecting endometrial polyps, a sensitivity and specificity of 13% and 100%, respectively, with an accuracy of 98% for submucous myomas, and values of 25%, 92%, and 80%, respectively, in diagnosing hyperplasia. On the other hand, hysteroscopy demonstrated a sensitivity of 100% and a specificity of 97%, with an accuracy of 91% in diagnosing endometrial polyps, a sensitivity and specificity of 100% and 98%, respectively, with an accuracy of 99% for submucous myomas. The coefficient of concordance kappa (95% CI) was 0.12 for blind biopsy and 0.82 for hysteroscopy, corresponding, respectively, to slight concordance and almost perfect agreement with final pathologic diagnosis. CONCLUSIONS: Blind biopsy (Novak's curette) demonstrates very low sensitivity and accuracy in the diagnosis of benign focal intracavitary lesions. Hysteroscopy is confirmed as the gold standard in the assessment of abnormal uterine bleeding in menopause, permitting the elimination of the false-negative results of blind biopsy through direct visualization of the uterine cavity and the performance of targeted biopsy in case of doubt.     

Hysteroscopic evaluation of menopausal women with endometrial thickness of 4 mm or more

STUDY OBJECTIVE: To assess the diagnostic and operative potential of hysteroscopy in postmenopausal patients selected by ultrasound criteria. DESIGN: Cohort study (Canadian Task Force classification II-2). SETTING: Outpatient ultrasound and hysteroscopy department of a university-affiliated hospital. PATIENTS: One hundred fifty-five postmenopausal women with endometrial thickness of 4 mm or more by ultrasound, in menopause for at least 1 year, with or without menopausal complaints. INTERVENTIONS: Transvaginal ultrasound and office hysteroscopy with eye-directed biopsy specimens using a 5-mm, continuous-flow, operative hysteroscope. MEASUREMENTS AND MAIN RESULTS: Of the 155 women, 129 (83%) were asymptomatic (irregular bleeding). Hysteroscopy showed endometrial pathology in 28% of asymptomatic patients (23 polyps, 5 cases of hyperplasia, 8 submucous myomata) and 76% of symptomatic women (13 polyps, 6 hyperplasia, 1 submucous myoma). Hysteroscopic results compared with histologic diagnosis showed a positive predictive value equal to 97. 1% and 95% in asymptomatic and symptomatic women, respectively, and a negative predictive value equal to 100% in both groups. CONCLUSION: Office hysteroscopy with endometrial biopsy samples has a diagnostic and operative role in postmenopausal patients selected based on endometrial thickness on ultrasound, in view of the high prevalence of endometrial pathology in both symptomatic and asymptomatic women.     

Endometrial thickness in tamoxifen-treated patients: an independent predictor of endometrial disease.

OBJECTIVE: To assess the independent contribution of transvaginal ultrasound in identifying women at risk for endometrial disorders, and determine whether a cutoff value identifies women who need endometrial histologic assessment. METHODS: Postmenopausal women with breast cancer who were receiving tamoxifen, with ultrasonographic endometrial thickness greater than 4 mm or vaginal bleeding, had hysteroscopy with selective endometrial biopsies. Endometrial thickness, duration of tamoxifen therapy, and endometrial histology were studied. Parametric and nonparametric tests and logistic regression and receiver operating characteristic curves were used for statistical analysis. RESULTS: The study population consisted of 163 women, 46 with vaginal bleeding. The proportion of women with abnormal histologic findings was greater among those with endometrial thicknesses exceeding 9 mm compared with those with endometrial thicknesses 9 mm or less (60% versus 6.1%, P < .001) and among women who received tamoxifen for more than 27 months than those who received it for less time (46% versus 16%, P < .005). Logistic regression showed that endometrial thickness greater than 9 mm and vaginal bleeding were independent predictors of abnormal findings at hysteroscopy. CONCLUSION: In women taking tamoxifen, sonographic endometrial thickness exceeding 9 mm and the presence of vaginal bleeding are independent predictors of endometrial disease. If either exists, hysteroscopy and biopsy should be done.     

Uterine cavity assessment in infertile women: comparison of transvaginal sonography and hysteroscopy.

OBJECTIVES: To evaluate the diagnostic accuracy of transvaginal sonography (TVS) in detecting uterine cavity abnormalities in infertile patients, with reference to hysteroscopy as the gold standard method. STUDY DESIGN: At the Institute of Obstetrics and Gynaecology, University of Bari, 134 infertile women were investigated with both TVS and hysteroscopy. In all cases endometrial biopsy was performed. Sensitivity, specificity, and positive and negative predictive values were calculated for TVS, considering hysteroscopic diagnosis as the gold standard. Statistical analysis was performed by using McNemar test. RESULTS: There was one failed insertion of hysteroscope. Hysteroscopy diagnosed pathological findings in 58 out of 133 cases (44%). TVS was in agreement with 50 of the 58 (86%) of the pathological findings diagnosed at hysteroscopy. As a test for the detection of uterine cavity abnormalities, TVS in comparison with hysteroscopy had 84.5% sensitivity and 98.7% specificity, 98.0% positive predictive value and 89.2% negative predictive value. CONCLUSIONS: TVS is able to diagnose polyps, septum and submucous fibroids with quite significant accuracy, while hysteroscopy is indicated for their confirmation and removal. Thus, hysteroscopy provides both diagnostic and therapeutic capabilities, but TVS permits to proceed directly to operative hysteroscopy avoiding the need for a separate diagnostic procedure.     

Sonographic, hysteroscopic, histological correlation in the early diagnosis of endometrial carcinoma.

The authors evaluate the diagnostic role of hysteroscopy and sonography in the early detection of endometrial cancer. In their experience diagnostic accuracy of transabdominal ultrasound was 87.5%; the introduction of transvaginal sonography increased it up to 95.8%, whereas hysteroscopy had diagnostic accuracy of 100%. The hysteroscopy allowed us to establish cervical canal involvement in 100% of cases. Since sonography is well accepted by patients, the authors propose to perform it in high risk patients once a year as a first level exam to show abnormal endometrial echoes. Therefore patients can be selected to undergo hysteroscopy and, if necessary, biopsy.     

Uterine pathologies in patients undergoing tamoxifen therapy for breast cancer: ultrasonographic, hysteroscopic and histological findings

PURPOSE OF INVESTIGATION: To evaluate endometrial abnormalities by ultrasonography, hysteroscopy and biopsy in postmenopausal patients treated with tamoxifen as adjuvant therapy for breast cancer. METHODS: The study was carried out on 113 patients who underwent vaginal ultrasonography, hysteroscopy and endometrial biopsy. RESULTS: There was a significative relation between ultrasonographic and hysteroscopic features (p < 0.001); 58 polyps were diagnosed at hysteroscopy, although 35 were not found at ultrasonography. A significant relation between ultrasonographic and histological findings was also documented (p < 0.005). A significant relation between histological findings and symptomatology was found (p < 0.05), although pathologies were also present in asymptomatic women. CONCLUSIONS: These results show that long-term tamoxifen therapy in breast cancer patients is associated with a higher incidence of uterine pathology. No significant relation has been documented between duration of treatment and grade of endometrial lesion (p > 0.05). Ultrasonography alone is useful in asymptomatic patients because it selects patients with increased endometrial thickness who should undergo hysteroscopy. Hysteroscopy is more accurate in detecting polyps, hyperplastic and neoplastic changes. Asymptomatic tamoxifen treated women should be evaluated as symptomatic patients.     

Reliability of out-patient hysteroscopy in one-stop clinic for abnormal uterine bleeding

This study aims to estimate the effect of adding office hysteroscopy to the preoperative diagnostic work-up in abnormal uterine bleeding on the diagnostic accuracy. It is a prospective comparative diagnostic trial at a tertiary care referral facility and a university hospital. There were a total of 295 patients, more than 35?years old, with abnormal uterine bleeding. The patients had vaginal sonography, office hysteroscopy, and office endometrial biopsy on one-stop bases. The diagnostic accuracy of each method in diagnosing focal lesion and endometrial hyperplasia was measured as the main outcome of this paper. Combined hysteroscopy and biopsy were taken as the gold standard for diagnosing focal lesion while endometrial biopsy alone was the gold standard for diagnosing endometrial hyperplasia. Office hysteroscopy was superior to other methods for diagnosing focal lesion with about half of the focal lesions failing to be diagnosed with the other two methods. Office hysteroscopy was superior to vaginal sonography in diagnosing endometrial hyperplasia. Office hysteroscopy is an indispensable tool for diagnosing abnormal uterine bleeding and without its use, half of the focal lesions could be missed. Office setting and the one-stop approach greatly facilitate the use of the combination of office hysteroscopy with vaginal sonography and office endometrial sample.     

Hysteroscopy and transvaginal ultrasonography in postmenopausal women with uterine bleeding.

OBJECTIVE: To evaluate the accuracy of hysteroscopy and transvaginal ultrasonography (TU), based on a histopathological report from endometrial specimens, in diagnosing endometrial pathology in menopausal women with uterine bleeding. METHODS: Four-hundred and nineteen postmenopausal women with uterine bleeding underwent TU, hysteroscopy and endometrial biopsy. Hysteroscopic and sonographic findings have been evaluated on the basis of the final diagnosis established by histologic examination. Sensitivity, specificity and positive predictive value of TU at an endometrial thickness cut-off point of 4 and 8 mm (double layer technique) and of panoramic hysteroscopy have been detected. RESULTS: Normal and abnormal endometrium was found in 222 and in 197 women, respectively. TU showed sensitivity of 95.1%, specificity of 54.8% and positive predictive value of 63.7% at a cut-off limit of 4 mm. With a cut-off limit of 8 mm the corresponding figures were 83.8%, 81.3% and 79.4%. Hysteroscopy demonstrated a sensitivity of 96.5%, specificity of 93.6% and positive predictive value of 92.6%. The combination of the two diagnostic tools showed a 100% sensitivity, 94.8% specificity and 93.3% positive predictive value. CONCLUSIONS: With cut-off limit of 4 mm, TU can be considered the first choice modality of endometrial investigation in women with postmenopausal uterine bleeding to select patients at risk to carry endometrial pathology. Hysteroscopy is a more accurate technique than TU because of better specificity and must be indicated for all patients showing an endometrial strip more than 4 mm. When an endometrial thickness below 4 mm is detected by ultrasound, hysteroscopy may be indicated on clinical background because of the possibility to miss infrequent (2.5% in our series), but relevant endometrial pathologies. Endometrial sampling should follow hysteroscopic view in all cases showing abnormal or suspicious lesions as well as in all cases with irregularly shaped endometrial lining and/or suboptimal endoscopic vision.     

Pretreatment and prospective assessment of endometrium in menopausal women taking tamoxifen for breast cancer

OBJECTIVES: To estimate the pretreatment incidence of endometrial pathology and to prospectively assess the endometrial morbidity emerging during tamoxifen intake for breast cancer. STUDY DESIGN: One-hundred and forty-six menopausal breast cancer patients, candidate to receive tamoxifen underwent endometrial assessment by Transvaginal Ultrasonography (TU) before the start of therapy. A double-layered endometrial stripe measuring more than 4mm indicated hysteroscopy and endometrial biopsy. Endometrial abnormalities detected before the start of tamoxifen were treated by operative hysteroscopy or by hysterectomy; no therapy and yearly hysteroscopic follow-up was scheduled for patients showing non-atypical hyperplasias. All women were asked to undergo TU on a yearly basis; during the follow-up period, indication for hysteroscopy and endometrial biopsy were the following: (i) an endometrial lining measured above 4mm at the first time, (ii) at least a 50% increase of endometrial thickness since the last finding in patients previously assessed by hysteroscopy, (iii) a recorded vaginal bleeding, and (iv) previous findings of endometrial hyperplasia. Histopathologic result from biopsy or hysterectomy was the reference test to establish the baseline prevalence of endometrial pathology and the emerging prevalences of morbidity after 12, 24, 36, 48 and 60 months of tamoxifen therapy. RESULTS: One-hundred and five patients were followed for 60 months, whereas 113, 126, 137 and 141 patients were evaluated up to 48, 36, 24 and 12 months, respectively. In 44 out of 146 patients, pretreatment TU showed an endometrium thicker than 4mm and in 31 (21.2%) of these patients abnormalities consisting of 16 endometrial polyps, seven polyps harboring simple hyperplasia, four simple hyperplasias, three atypical hyperplasias and one adenocarcinoma were found. During tamoxifen intake benign endometrial abnormalities were detected in 36 out of 114 assessable patients showing normal endometrium before the start of tamoxifen therapy (31.5%) and in seven out of 27 patients with baseline endometrial abnormalities (25.9%). Overall, an endometrial pathology emerged in 30.4% of patients during tamoxifen administration and in no patients we found an atypical lesion. CONCLUSIONS: In menopausal breast cancer patients the incidence of endometrial abnormalities before the start of tamoxifen therapy is high and includes 2.7% of atypical pathology. After the diagnosis and treatment of baseline atypical lesions were accomplished, no atypical endometrial lesion emerged after the start of tamoxifen administration. Based on these findings, we believe that pretreatment assessment of endometrium is recommended in all menopausal women candidate to receive tamoxifen therapy.     

Vaginoscopic hysteroscopy in management for women with post-menopausal vaginal bleeding

ObjectivesThe feasibility of vaginoscopic hysteroscopy combined with office endometrial biopsy after ultrasonography for management of post-menopausal vaginal bleeding (PMB).Materials and methodsA prospective observational study of with PMB whom attending the Outpatient Clinic of Kang Ning Hospital during a four months period (1st Feb to 31st May 2018) was included. Vaginoscopic hysteroscopy was performed with endometrial biopsy after the initial clinical pelvic examination and transvaginal ultrasound examination.ResultsA total of 45 consecutive women with PMB was included. The hysteroscopy and endometrial biopsy were successful in 44 out of 45 (98%), a complete view in 82%, adequate tissue was in 91%, only one case was failed both procedures due to pain. The correlation between hysteroscopy and endometrial biopsy by was 100%. The mean operation time was 229 ± 68 s. The most common histological findings was atrophic endometrium 18 (42%). Five endometrial polyps and 2 submucosal leiomyomas were found. One rare case of endometrial carcinosarcoma (2%) was detected. Patients reported less pain for hysteroscopy than endometrial biopsy with rated VAS pain score was 3.5 ± 2.2, with 5 more score in 18%, and for endometrial biopsy 4.2 ± 2 and 33% respectively (p < 0.001). Six cases (13%) experienced vasovagal attacks immediately after the procedure. There is no other complication.ConclusionThe Vaginoscopic hysteroscopy combined endometrial biopsy is safe and feasible for assessment of endometrial pathology with postmenopausal bleeding.     

Hysteroscopic evaluation of the endometrium in postmenopausal women taking tamoxifen

STUDY OBJECTIVE: To evaluate hysteroscopic endometrial changes due to tamoxifen therapy in postmenopausal women with breast cancer. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. Patients. Eighty-eight postmenopausal women (or with iatrogenic amenorrhea) receiving tamoxifen 20 mg/day for at least 1 year for breast cancer. INTERVENTION: Record review of patients undergoing transvaginal sonography (TVS) and office hysteroscopy with eye-directed biopsy specimens obtained with a 5-mm, continuous-flow, operative hysteroscope. MEASUREMENTS AND MAIN RESULTS: Patients with thickened endometrium and pathologic findings at hysteroscopy had taken tamoxifen for significantly longer times than those without such findings (p < 0.05). CONCLUSION: Our findings confirm the estrogenic effect of tamoxifen on endometrium. Endometrial evaluation by TVS suggests further diagnostic procedures, but only hysteroscopy allows the surgeon to visualize endometrial lesions and obtain eye-directed biopsy tissue.

目的:探讨宫腔镜注水膨宫时经腹超声评估剖宫产术后子宫切口憩室大小、残余肌层厚度的应用价值。方法:选取剖宫产术后出现月经经期改变,伴随月经前后点滴出血的患者37例,同时采用经阴道超声及宫腔镜注水膨宫下经腹超声测量憩室长、宽、高、深及残余肌层厚度,比较两种检测手段对于评估子宫切口愈合情况的优劣。结果:宫腔镜注水膨宫时经腹超声检测憩室长、宽、高各径线均大于普通阴道超声(P0.05),而残余肌层厚度更薄(P0.05)。3例患者普通阴道超声未检测出憩室,而宫腔镜膨宫下能观察到典型的憩室形态。结论:宫腔镜注水膨宫时经腹超声在测量憩室大小的同时能直观地观察憩室内部形态,取得病理,排除子宫内膜其他良恶性病变,与普通经阴道超声相比,能更好地评估憩室。     

Comparison of ultrasonography,hysteroscopy, and biopsy in the diagnosis of endometrial lesions in postmenopausal tamoxifen-treated patients

BACKGROUND: At present, no proven recommendations can be made for the surveillance of tamoxifen-treated women. The aim of the present study was to evaluate ultrasonography and hysteroscopy in this setting. METHODS: Three hundred and ten postmenopausal patients using tamoxifen underwent vaginal ultrasonography, hysteroscopy, and endometrial biopsy; 274 were asymptomatic and 49 had abnormal bleeding. Ultrasonographic endometrial thickness and echotexture were recorded. Hysteroscopic endometrial appearance, presence of focal endometrial lesions and polyps were also recorded. General or selective endometrial biopsy was performed. Ultrasonographic and hysteroscopic follow up was provided. RESULTS: At ultrasonography, mean endometrial thickness was 10.8 mm. At hysteroscopy, cystic atrophy and suspect focal lesions were detected in 49.2% and 5.3% of women, respectively. Polyps were present in 44.8% of women; 38.9% of these polyps were missed at ultrasonography, whereas 11.4% were suspected but were not found at hysteroscopy. At biopsy, non-atypical hyperplasia and atypical changes were found in 4.8% and 1.3% of patients, respectively. Three carcinomas were found, all in asymptomatic women. Logistic regression analysis showed that only suspect focal lesions at hysteroscopy were significantly associated with abnormal histology. With a 6-mm cut-off value for endometrial thickness, negative and positive predictive values for ultrasonography in detecting hyperplastic or neoplastic changes were 96% and 8%, respectively; the corresponding values for hysteroscopy were 96% and 65%. No additional carcinoma was found at follow up. CONCLUSIONS: No single ultrasonographic feature (echotexture and borders) is significantly associated with the detection of endometrial hyperplasia or carcinoma; hysteroscopy, although not predictive unless revealing a focal lesion, is more accurate in detecting polyps and hyperplastic changes.     

Hysteroscopy in perimenopausal and postmenopausal women with abnormal uterine bleeding

From February 1983 to January 1985, we performed outpatient microhysteroscopic examinations on 618 women 45 years of age or older with abnormal uterine bleeding (AUB). Three hundred thirty-four (54%) had normal and functional or hypoatrophic endometrium, 78 (12.6%) had low-risk hyperplasia, 8 (1.3%) had high-risk hyperplasia, and 66 (10.6%) had adenocarcinoma. Correlation with histologic findings revealed the considerable diagnostic accuracy of the technique: its reliability approaches 100% when one deals with endometrial neoplasia, 87.5% with high-risk hyperplasia and 65.2% with low-risk hyperplasia. The diagnosis cannot rely on hysteroscopic examination only. A biopsy can be performed during the examination or immediately thereafter. In 54.1% of AUB patients, no endometrial changes could be detected on hysteroscopy and biopsy. Curettage, therefore, would have resulted in overtreatment of these patients. Moreover, the usefulness of dilatation and curettage in about half of AUB patients over 45 should be questioned seriously.     

Accuracy of preoperative diagnostic tools and outcome of hysteroscopic management of menstrual dysfunction

STUDY OBJECTIVES: To review diagnoses, complications, and surgical findings in women treated for abnormal uterine bleeding by operative hysteroscopy, and to assess the accuracy of preoperative transvaginal ultrasound (TVS), saline-infusion sonography (SIS), diagnostic hysteroscopy, and endometrial biopsy. DESIGN: Retrospective study (Canadian task force classification II-2). SETTING: Tertiary care academic medical center. PATIENTS: Three hundred seventy-five women. Intervention. Operative hysteroscopy for abnormal uterine bleeding. MEASUREMENTS AND MAIN RESULTS: Main indications for hysteroscopy were postmenopausal bleeding (164 patients, 43.7%) and abnormal premenopausal uterine bleeding (211, 56.3%). Main pathology findings were endometrial polyps (172, 45.9%) and submucous myomas (105, 28%). Polyps had histologic abnormalities in 18 patients. Sensitivity of preoperative diagnostic tools for all intrauterine abnormalities and specifically for myomas and polyps was TVS 74% and 39%, SIS 96% and 96%, hysteroscopy 100% and 99%, and Pipelle biopsy 24% and 10%. The complication rate was 1.3%. Postmenopausal women felt significantly more improvement in symptoms (p = 0.02), and were more satisfied (p 相似文献   

Atypical hyperplasia of endometrium and hysteroscopy

OBJECTIVE: To evaluate the risk of discovering an endometrial cancer when atypical hyperplasia was diagnosed by either endometrial samples using the pipelle device or hysteroscopic resection products. PATIENTS AND METHODS: A retrospective monocentric study from january 1990 to july 2000. Twenty-three patients with atypical hyperplasia were included. Initial endometrial status was provided by endometrial biopsyduring diagnosis hysteroscopy (12 cases) or by operative hysteroscopic resection products (11 cases). For 23 patients, operative hysteroscopy and analyse of products resected were performed. For all patients, there was no hysteroscopical aspect evocative of adenocarcinoma. For 23 patients, histopathological analysis of the hysterectomy piece precised the final diagnosis. RESULTS: Among the 23 hysterectomy pieces, 7 adenocarcinomas were diagnosed (30.4%). Risk for discovering adenocarcinoma when atypical hyperplasia was diagnosed by means of the pipelle biopsy device was 50% (6/12). Risk for discovering adenocarcinoma when atypical hyperplasia was diagnosed by means of operative hysteroscopy resection products was 5.9 % (1/17). DISCUSSION AND CONCLUSION: Atypical endometrial hyperplasia evidenced by pipelle biopsy device is often associated with adenocarcinoma. Diagnosis hysteroscopy however does not show evident pathological aspect of adenocarcinoma in such cases. Operative hysteroscopy allows in most cases correction of endometrial status. Risk of omitting adenocarcinoma when atypical hyperplasia is discovered on hysteroscopic resection pieces is low.     

Comparison of transvaginal ultrasonography and vaginal sonohysterography in the detection of endometrial polyps

BACKGROUND: The diagnostic accuracy of transvaginal ultrasonography and vaginal sonohysterography in detecting endometrial polyps in women suffering abnormal uterine bleeding are compared. METHODS: One hundred and six patients suffering from menometrorrhagia were studied. To detect whether there was endometrial polyp or not, these patients were subjected to transvaginal ultrasonographic examination as well as to sonohysterography. The final diagnosis was established by diagnostic hysteroscopy and its guided biopsy. RESULTS: Transvaginal ultrasonography resulted in false positive and false negative rates of 25% and 36.2% respectively while the figures with sonohysterography were 5.4% and 8% respectively. Combining both techniques further improved such rates to 2.9% and 2.8% respectively but not significantly (p>0.1). The sensitivity and specificity were 64.5%, 75.5% for transvaginal ultrasonography, and 93.1%, 93.9% for sonohysterography (significantly higher: p<0.001). CONCLUSIONS: Sonohysterography is significantly more accurate than transvaginal ultrasonography in the detection of endometrial polyps in cases with abnormal uterine bleeding. Combining both techniques did not significantly improve the diagnostic accuracy. Sonohysterography is an accurate and cost effective method which requires a little skill.
