Clinicopathological Pattern of Endometrial Specimens in Women with Abnormal Uterine Bleeding and Ultrasonography Correlation

BACKGROUND

Abnormal uterine bleeding (AUB) refers to any symptomatic deviation from normal menstruation. AUB is a common gynecological disorder in non-pregnant women of reproductive age, accounting for approximately 33% of gynecological outpatient visits. The early diagnosis and management cause of AUB is important because of increased incidence of endometrial carcinoma with rapid growth. Transvaginal ultrasound is non-invasive imaging technique used to find endometrial carcinoma before referring patients for invasive techniques. Dilatation and curettage (D&C) and endometrial biopsy are surgical procedures that scrape the endometrial lining of the uterus for diagnosis and treatment. The aim of this study is to describe the clinicopathologic pattern of endometrial specimens in women with AUB and ultrasonographic correlation.

METHODS

Tissues from endometrial biopsy and curettage of 411 patients with AUB who referred to Shahid Mohammadi hospital were prospectively selected from 2021 to 2023. Patients were divided into three groups based on age and menstrual status including: premenopausal (18-39 years), perimenopausal (40-49 years) and postmenopausal (≥50 years). The results were correlated to patient's age and other data and evaluated with statistical analysis.

RESULTS

During the two-year study period, a total of 411 endometrial specimens with clinical diagnosis of AUB were submitted and the results were analyzed. The youngest patient presenting with AUB was 21 years old, while the oldest was 77 years old. The most common complaint was menorrhagia in 201 (48.0%) out of 411 patients. The most common pathology finding in three groups was polyp in 100 (24.3%) cases. Hormonal effect was the next commonly observed pattern seen in 70 (17.0%) cases. P value was calculated as 0.003 which was significant using chi-square for the trend seen in age.

CONCLUSION

Endometrial sampling is a useful tool for evaluation of women with AUB and referring patients for treatment. Histopathological evaluation of the endometrium is very useful in detecting the etiology of AUB. Transvaginal sonography has high sensitivity in detecting polyps.

D&C has the best concordance between preoperative and postoperative grades among morbidly obese endometrial cancer patients

AIM

Endometrial cancer is diagnosed by obtaining uterine biopsies by pipelle, dilatation and curettage (D&C), or hysteroscopy. In 15%-25% of the cases, the preoperative and postoperative grades do not match. This discrepancy may carry significant clinical and prognostic consequences. We aimed to assess how body mass index (BMI) affects preoperative and postoperative grade mismatches and whether biopsy methods mitigate this effect.

METHODS

We conducted a retrospective review of patients with endometrial cancer who underwent surgery at our center between 2014 and 2022. We stratified patients into six classes of BMI based on the WHO classification. Preoperative and postoperative grades were compared for concordance with regards to patient BMI and sampling method.

RESULTS

A total of 158 patients were included, diagnosed by pipelle (n = 99), hysteroscopy (n = 15), or D&C (n = 44). For all methods, every unit increase in BMI increased the odds of having a gap between histology grades by 5.2%. In the pipelle group, the odds of a larger gap between the histology grades was 62% higher than that of women in the other groups. Among the D&C group, the odds of having a bigger difference between histology grades were 91.8% lower compared to the other groups. Patients with BMI over 30 had nearly 50% discrepancy when diagnosed with pipelle or hysteroscopy, but less than 10% with D&C.

CONCLUSIONS

Increasing BMI is associated with decreasing concordance between preoperative and postoperative grades in endometrial cancer, especially when it exceeds 30. This effect is much less pronounced, however, when the diagnostic method is D&C.

Does repetitive dilatation and curettage or hysteroscopic biopsy in patients treated with progestins for endometrial hyperplasia or carcinoma affect subsequent fetomaternal outcomes? A population-based study using the National Health Insurance Research Database of Taiwan

OBJECTIVE

To investigate the impact of repeated dilatation and curettage or hysteroscopic biopsy on fetomaternal outcomes in patients receiving progestin treatment for endometrial hyperplasia or early-stage carcinoma.

METHOD

This was a population-based study using the Taiwan National Health Insurance Research Database between 2009 and 2017 of women who gave birth and had a history of endometrial hyperplasia and early-stage carcinoma treated with progestins. Logistic regression analysis was used to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) reflecting the association between repeated procedures and fetomaternal outcomes.

RESULTS

A total of 6956 women with 8690 deliveries were identified. Compared with those who had two or fewer procedures, women who received more than two procedures had a significantly higher risk for cervical insufficiency (aOR, 5.09 [95 CI, 2.31-11.24]). Furthermore, women who had more than two procedures were prone to have adverse neonatal outcomes, including Apgar score < 7 at 1 min (aOR, 1.97 [95% CI, 1.13-3.43]) and 5 min (aOR, 3.11 [95% CI, 1.33-7.23]) and preterm delivery <32 weeks (aOR, 2.86 [95% CI, 1.50-5.45]).

CONCLUSION

Undergoing more than two procedures was associated with subsequent maternal cervical insufficiency, preterm delivery <32 weeks, and low neonatal Apgar score. Health care providers should be aware of the potential risks and balance the benefits and harms of repeated procedures.

Hysteroscopic biopsy compared with endometrial curettage to assess the preoperative rate of atypical hyperplasia underestimating endometrial carcinoma

PURPOSE

To evaluate the rate of atypical hyperplasia (AH) underestimating endometrial cancer (EC) comparing endometrial biopsy (EB) accomplished by hysteroscopic biopsy with dilatation and curettage (D&C). Second, to compare the two techniques to foresee EC grading.

METHODS

This trial was based on the findings of two Gynecological Departments within the same Public Utility, sharing pathological service and database but routinely performing EB under hysteroscopic visualization (group A) or hysteroscopy followed by D&C (group B). We retrieved the clinical data of patients showing EC on hysterectomy throughout a 10-year period. The accuracy of hysteroscopic-view diagnosis and EB pathology were compared, having the pathologic findings of hysterectomy as reference.

RESULTS

A total of 161 patients met the inclusion criteria. Among these, 109 and 52 were included in groups A and B, respectively. In group A, 32.1% of patients underwent EB in an out-patient setting. To foresee EC, hysteroscopic view showed a sensitivity of 82.5% and 70.2% in groups A and B, respectively (P = 0.019). An underestimation of EC diagnosed as AH on EB was found in 20 patients (12.4%). Among these, 18 (16.5%) and 2 (3.8%) were included in groups A and B, respectively (P = 0.022). In group A, a fault diagnosis of AH resulted higher when EB was performed as out-patient setting (P = 0.006). EB allowed the grading of EC in 73.3% and 90.3% of patients in groups A and B, respectively. The agreement was 73.7% and 85.1%, leading to moderate (κ = 0.56) and good (κ = 0.77) "κ" coefficient of concordance for groups A and B, respectively.

CONCLUSIONS

EB performed by D&C lowers the rate of AH underestimating concurrent EC and improves the grading agreement when compared with hysteroscopic sampling.

Obstetric outcomes after medroxyprogesterone acetate treatment for early stage endometrial cancer or atypical endometrial hyperplasia: a single hospital-based study

BACKGROUND

To investigate perinatal outcomes in pregnancy after high-dose medroxyprogesterone acetate (MPA) therapy for early stage endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) and to determine whether pregnancy after MPA therapy is at a higher risk of placenta accreta.

METHODS

Data of 51 pregnancies in 46 women who received MPA therapy for EC or AEH and delivered after 22 weeks of gestation at Keio University Hospital were reviewed. A retrospective matched case-control study was performed to determine the risk of placenta accreta in pregnancy after MPA therapy compared with singleton pregnancies without any history of maternal malignancy treatments.

RESULTS

The incidence of placenta accreta was higher in the MPA group than in the control group (15.7 vs. 0%, p = 0.0058). However, no differences in other perinatal outcomes were observed between groups. While gestational weeks at delivery in the MPA group were later than those in the control group (p = 0.0058), no difference in the incidence of preterm delivery was recorded between groups. In the MPA therapy group, the number of patients who underwent ≥ 6 dilation and curettage (D&C) was higher in the placenta accreta group than in the non-placenta accreta group (50.0 vs. 14.0%, p = 0.018). Patients with ≥ 6 D&Cs demonstrated a 6.0-fold increased risk of placenta accreta (p = 0.043, 95% CI 1.05-34.1) than those receiving ≤ 3 D&Cs.

CONCLUSION

Pregnancy after MPA therapy is associated with a high risk of placenta accreta. In cases in which the frequency of D&C is high, placenta accreta should be considered.

Effect of an Active vs Expectant Management Strategy on Successful Resolution of Pregnancy Among Patients With a Persisting Pregnancy of Unknown Location: The ACT or NOT Randomized Clinical Trial

IMPORTANCE

Women with an early nonviable pregnancy of unknown location are at high risk of ectopic pregnancy and its inherent morbidity and mortality. Successful and timely resolution of the gestation, while minimizing unscheduled interventions, are important priorities.

OBJECTIVE

To determine if active management is more effective in achieving pregnancy resolution than expectant management and whether the use of empirical methotrexate is noninferior to uterine evacuation followed by methotrexate if needed.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter randomized clinical trial recruited 255 hemodynamically stable women with a diagnosed persisting pregnancy of unknown location between July 25, 2014, and June 4, 2019, in 12 medical centers in the United States (final follow up, August 19, 2019).

INTERVENTIONS

Eligible patients were randomized in a 1:1:1 ratio to expectant management (n = 86), active management with uterine evacuation followed by methotrexate if needed (n = 87), or active management with empirical methotrexate using a 2-dose protocol (n = 82).

MAIN OUTCOMES AND MEASURES

The primary outcome was successful resolution of the pregnancy without change from initial strategy. The primary hypothesis tested for superiority of the active groups combined vs expectant management, and a secondary hypothesis tested for noninferiority of empirical methotrexate compared with uterine evacuation with methotrexate as needed using a noninferiority margin of -12%.

RESULTS

Among 255 patients who were randomized (median age, 31 years; interquartile range, 27-36 years), 253 (99.2%) completed the trial. Ninety-nine patients (39%) declined their randomized allocation (26.7% declined expectant management, 48.3% declined uterine evacuation, and 41.5% declined empirical methotrexate) and crossed over to a different group. Compared with patients randomized to receive expectant management (n = 86), women randomized to receive active management (n = 169) were significantly more likely to experience successful pregnancy resolution without change in their initial management strategy (51.5% vs 36.0%; difference, 15.4% [95% CI, 2.8% to 28.1%]; rate ratio, 1.43 [95% CI, 1.04 to 1.96]). Among active management strategies, empirical methotrexate was noninferior to uterine evacuation followed by methotrexate if needed with regard to successful pregnancy resolution without change in management strategy (54.9% vs 48.3%; difference, 6.6% [1-sided 97.5% CI, -8.4% to ∞]). The most common adverse event was vaginal bleeding for all of the 3 management groups (44.2%-52.9%).

CONCLUSIONS AND RELEVANCE

Among patients with a persisting pregnancy of unknown location, patients randomized to receive active management, compared with those randomized to receive expectant management, more frequently achieved successful pregnancy resolution without change from the initial management strategy. The substantial crossover between groups should be considered when interpreting the results.

Caesarean scar ectopic pregnancy: a case series and case report to highlight the experience in regional New Zealand

AIMS

To evaluate the approach to diagnosis and management of caesarean scar pregnancy (CSP) at a regional New Zealand hospital.

METHODS

A retrospective case series of ten patients between June 2015 and May 2020. The data review included demographic information, ultrasound findings, human chorionic gonadotropin (HCG) levels, primary and subsequent treatment, outcomes and complications.

RESULTS

Nine women were diagnosed with CSP at a gestational age between four and ten weeks. One of these women was treated twice for two separate CSP within the study period. Treatment varied according to clinical presentation, HCG levels, gestational age, ultrasound findings and patient preference. Two thirds of women were successfully treated with primary management, with one third requiring multiple treatment modalities. We report one severe life-threatening haemorrhage and three cases resulting in hysterectomy. We also show a disproportionate number of Māori women presenting with CSP.

CONCLUSION

We present a series of ten cases of CSP and demonstrate similar challenges in regional New Zealand to those reported elsewhere. Management is heterogeneous with little guidance from the literature, and primary management was successful in seven out of ten cases. We report a disproportionately high number of cases in Māori women. Our results would support the development of a national register for caesarean scar pregnancy to improve diagnosis and management across New Zealand.

Homelessness, housing instability, and abortion outcomes at an urban abortion clinic in the United States

BACKGROUND

Adverse reproductive health outcomes are well documented among people experiencing homelessness or housing instability. Little is known about abortion outcomes among this population.

OBJECTIVE

This study aimed to investigate the relationship between housing status and abortion outcomes and whether gestational age mediates this relationship.

STUDY DESIGN

Our sample comprised 1903 individuals who had abortions at an urban clinic in San Francisco, CA, from 2015 to 2017. We defined homelessness or housing instability as a binary exposure, which included staying outside, with friends and/or family, or in a tent, vehicle, shelter, transitional program, or hotel. We evaluated gestational duration of ≥20 weeks as a mediator variable. Our primary outcome was any abortion complication. Logistic regression models were adjusted for age, race, substance use, mental health diagnoses, and previous vaginal and cesarean deliveries.

RESULTS

Approximately 19% (n=356) of abortions were among people experiencing homelessness or housing instability. Compared with those with stable housing, people experiencing homelessness or housing instability presented later in pregnancy (mean gestational duration, 13.3 vs 9.5 weeks; P<.001) and had more frequent complications (6.5% vs 2.8%; P<.001; odds ratio, 2.2; 95% confidence interval, 1.2-3.9). Adjusting for race, substance use, mental health diagnoses, and previous cesarean deliveries, individuals experiencing homelessness or housing instability were more likely to have abortion complications (odds ratio, 2.3; 95% confidence interval, 1.3-4.0). However, the relationship was attenuated after adjusting for gestational duration (odds ratio, 1.4; 95% confidence interval, 0.7-2.6), suggesting that gestational duration mediates the relationship between housing status and abortion complications.

CONCLUSION

Patients experiencing homelessness or housing instability presented later in gestation, which seems to contribute to the increased frequency of abortion complications.

Distinguishing between interstitial and angular pregnancies: Is there a role for saline infusion sonohysterography?

OBJECTIVE

Interstitial pregnancy occurs in the intramural segment of the Fallopian tubes, while angular pregnancy is one that is located in one of the lateral angles of the uterine cavity. The differential diagnosis and treatment of these conditions are important. We have used saline infusion sonohysterography (SIS) to help in differential diagnosis.

CASE REPORT

A 36-year-old female with a case of suspected left interstitial ectopic pregnancy was admitted. Her diagnostic laparoscopy showed no tubal ectopic pregnancy, and D&C demonstrated no villi. She underwent SIS which showed a sac in the interstitial part but close to the tubal ostium. The second case involves a 21-year-old female who was 9-weeks pregnant. Ultrasonography could not differentiate between interstitial and angular pregnancy. SIS clearly demonstrated angular pregnancy with a missed abortion, and therapeutic D&C was done smoothly.

CONCLUSION

From reviewing past literature, SIS does not appear to have any proven adverse effect on the pregnancy although it is not widely accepted. This article highlights the benefits of using SIS to aid in the differential diagnosis between the two conditions, especially in unusual cases like ours.

Mifepristone and Misoprostol Vs Misoprostol Alone in Second Trimester Termination of Pregnancy

Introduction

During the last decade, medical methods for second trimester abortion have considerably improved and become safe and more accessible. The combination of mifepristone and misoprostol is now an established and highly effective method for second trimester abortion. But where mifepristone is not available or affordable, misoprostol alone has also been shown to be effective. The objective of this study is to compare the efficacy of mifepristone with misoprostol and misoprostol alone for second trimester termination of pregnancy.

Methods

It is a comparative study conducted on 60 patients from 13 to 18 weeks of gestation admitted for second trimester termination on legal indications.

Results

Mean induction abortion interval was comparable in both the groups. Of the 30 cases in each group, nine cases in each Group A and six cases in Group B had incomplete/failed expulsion. Among these 15 cases, only nine required check curettage for complete evacuation while others received oxytocics only for completion. The distribution of these cases was also comparable in both the groups. Only one patient in Group B had complete failure of expulsion and underwent surgical evacuation. However, the difference in dosage of misoprostol required for complete expulsion and incidence of side effects were significantly higher in the group B.

Conclusions

Mifepristone and misoprostol combined together is now an established, highly effective and safe method for medical method of second trimester termination. However, when mifepristone is not available or affordable, misoprostol alone can also be used effectively, although a higher total dose is needed and side effects are higher than with the combined regimen.

Decision satisfaction among women choosing a method of pregnancy termination in the setting of fetal anomalies and other pregnancy complications: A qualitative study

OBJECTIVE

The decision to undergo a surgical or medical method of second-trimester termination for pregnancy complications should be preference-sensitive. Decision satisfaction has not been described in this population; understanding how women describe decision satisfaction in this setting could inform decision support efforts.

METHODS

We conducted qualitative interviews with women one to three weeks after termination who chose either a surgical or medical termination for fetal anomalies, pregnancy complications or fetal demise. We analyzed transcripts using modified grounded theory in an iterative manner with a generative thematic approach.

RESULTS

We interviewed 36 women (24 surgical and 12 medical). Subjects connected decision satisfaction with counseling experiences and their personal values, including (1) importance of adequate information, (2) autonomous decision making, and (3) choosing the method that facilitates coping.

CONCLUSION

Offering women a choice between surgical and medical termination procedures in the setting of pregnancy complications is integral to decision satisfaction. Women in our study reported wanting this decision to be driven by their personal values.

PRACTICE IMPLICATIONS

Women should be able to choose between surgical and medical termination based on preference and not availability of services. Decision support from women's health providers should be based on values clarification and providing accurate information.

Optimal treatment for women with a persisting pregnancy of unknown location, a randomized controlled trial: The ACT-or-NOT trial

OBJECTIVE

Pregnancy of unknown location (PUL) is not a diagnosis but a transient state used to classify a woman when she has a positive pregnancy test without definitive evidence of an intra-uterine or extra-uterine pregnancy on transvaginal ultrasonography. Management of a persisting PUL varies substantially, including expectant or active management. Active management can include uterine cavity evacuation or systemic administration of methotrexate. To date, no consensus has been reached on whether either management strategy is superior or non-inferior to the other.

DESIGN

Randomized controlled trial.

SETTING

Academic medical centers.

PATIENTS

We plan to randomize 276 persisting PUL-diagnosed women who are 18 years or older from Reproductive Medicine Network clinics and additional interested sites, all patients will be followed for 2 years for fertility and patient satisfaction outcomes.

INTERVENTIONS

Randomization will be 1:1:1 ratio between expectant management, uterine evacuation and empiric use of methotrexate. After randomization to initial management plan, all patients will be followed by their clinicians until resolution of the PUL. The clinician will determine whether there is a change in management, based on clinical symptoms, and/or serial human chorionic gonadotropin (hCG) concentrations and/or additional ultrasonography.

MAIN OUTCOME

The primary outcome measure in each of the 3 treatment arms is the uneventful clinical resolution of a persistent PUL without change from the initial management strategy. Secondary outcome measures include: number of ruptured ectopic pregnancies, number and type of re-interventions (additional methotrexate injections or surgical procedures), treatment complications, adverse events, number of visits, time to resolution, patient satisfaction, and future fertility.

CONCLUSION

This multicenter randomized controlled trial will provide guidance for evidence-based management for women who have persisting pregnancy of unknown location.

Oral contraceptive pills as an option for non-surgical management of retained products of conception - a preliminary study

Many Patients with persistent retained products of conception prefers to avoid surgical interventions, such as a dilatation and curettage (D&C) that might pose an additional future risk to their already compromised fertility or obstetric performance. The aim of this study was to the possibility of induced withdrawal bleeding following oral contraceptive administration as a non-surgical treatment for patients with persistent retained products of conception (RPOC). A retrospective study of patients presenting with retained products of conception (RPOC) after failed expectant management or after treatment with PGE1 was performed. Twelve women presenting with RPOC at ≤8 weeks gestation with minimal to mild vaginal bleeding and no signs of infection were treated with oral contraceptive pill (OCP) containing 0.03 mg ethinylestradiol and 0.15 mg of desogestrel for 3 weeks. Out of the 12 patients treated, nine women (75%) successfully expelled the RPOC after completing the three-week course of OCPs. The three cases (25%) that did not resolve following OCP treatment had pregnancy products with positive blood flow on Doppler examination. We conclude that OCPs may be a useful medical treatment option for persisting RPOC in selected patients with absence blood flow on Doppler examination wishing to avoid surgical intervention.

Hysteroscopy and Endometrial Cancer Diagnosis: A Review of 2007 Consecutive Examinations in Self-Referred Patients

The authors reviewed 2007 consecutive outpatient hysteroscopies performed in self-referred women to assess the detection rate of uterine cancer and the validity of different selection criteria for hysteroscopy. Thirty cases of uterine cancer (29 endometrial, 1 carcinosarcoma) were detected. Abnormal uterine bleeding was the indication most commonly associated with cancer (26 of 30 cases, cancer detection rate = 2.1 %), whereas the presence of cervical polyps had no predictive value. Patients age was correlated to cancer detection rate, and the investigation of uterine cancer under the age of 45 was poorly cost effective. Hysteroscopy and endometrial biopsy, performed by Permacurette or Novak curette immediately after hysteroscopy, missed respectively 8 and 2 of 30 cancers. Hysteroscopy should be employed in combination with endometrial biopsy as a standard outpatient investigation whenever endometrial cancer is suspected. These procedures are safe and accurate and rule out more aggressive and costly procedures, such as dilatation and curettage, in most cases.

Lipoma of round ligament on the intraperitoneal portion (abdominal site): a case report

Primary tumors of round ligament are rare, and when found are typically leiomyomas. Endometrioma, and mesothelial cysts are the benign lesions recognized as involving the round ligament. We report a case of lipoma of the round ligament in a 48-year-old premenopausal woman. Round ligament lipoma on the intraperitoneal portion (abdominal site) is very rare and it should be kept in the differential diagnosis of ovarian and abdominal masses.

Agreement of histopathological findings of uterine curettage and hysterectomy specimens in women with abnormal uterine bleeding

Objectives:

To examined the diagnostic value of dilatation and curettage (D&C) in patients with abnormal uterine bleeding (AUB) by conducting a histopathological examination of endometrial tissues by D&C and hysterectomy.

Methods:

In this retrospective study, the medical records of 163 women who had been hospitalized in the Obstetrics and Gynecology Ward, Amir-al-Momenin Hospital, Semnan, Iran between 2010 and 2015 for diagnostic curettage due to AUB and who had undergone hysterectomy were investigated. The patients’ characteristics and histopathologic results of curettage and hysterectomy were extracted, and sensitivity and specificity and positive and negative predictive values of curettage were calculated.

Results:

The mean ± standard deviation age of the patients was 49.8±7.8 years. The sensitivity values of D&C in the diagnosis of endometrial pathologies was 49.1%, specificity 84.5%, positive 60.5%, and negative predictive 77.5%. The sensitivities of D&C in the diagnosis of various endometrial hyperplasia was 62.5%, disordered proliferative endometrium 36.8%, and endometrial cancer 83.3%. Of 6 patients with endometrial polyps on performing hysterectomy, no patient was diagnosed by curettage.

Conclusions:

Dilatation and curettage has acceptable sensitivity in the diagnosis of endometrial cancer, low sensitivity in the diagnosis of endometrial hyperplasia, and very low sensitivity in the diagnosis of disordered proliferative endometrium and endometrial polyps.

Pooled analysis on the necessity of random 4-quadrant cervical biopsies and endocervical curettage in women with positive screening but negative colposcopy

Controversy remains over whether random cervical biopsies and endocervical curettage (ECC) should be used in women with positive screening but negative colposcopy. Our paper aims to determine the indications for random biopsies and ECC among these screened positive women.Three thousand two hundred thirteen women with any positive screening test result but negative colposcopy, who received random 4-quadrant biopsies, were pooled from 17 population-based cervical cancer screening studies done in China from 1999 to 2008. The detection rates of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and CIN grade 3 or worse (CIN3+) stratified by cytology and high-risk human papillomavirus (HR-HPV) status were assessed, as well as the false negative rates for CIN2+ and CIN3+ by random biopsies without ECC.Compared with women with negative cytology and positive HR-HPV, those with atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion (ASC-US/LSIL) and negative HR-HPV had the equivalent lower risks of CIN2+ and CIN3+, but ascending risks were observed in the groups of ASC-US/LSIL and positive HR-HPV, and atypical glandular cells/atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion/high-grade squamous intraepithelial lesion or worse (AGC/ASC-H/HSIL+). If random biopsies were only taken without ECC, 9.3% of CIN2+ and 18.5% of CIN3+ would have been missed.For women with any positive screening but negative colposcopy, in areas with good cytological infrastructure, it was necessary to perform random biopsies plus ECC on those with cytological ASC-US/LSIL and positive HR-HPV, AGC, ASC-H, or HSIL+. In contrast, those with other results should be followed up.

One-stop clinical assessment of risk for endometrial hyperplasia (OSCAR-Endo): a fast-track protocol for evaluating endometrial pathologies

PURPOSE

To evaluate a one-stop clinical assessment of risk for assessing endometrial pathologies (OSCAR-Endo), consisting of a fast-track protocol with hysteroscopy, dilation and curettage (D&C) with intraoperative frozen section analysis of the removed tissue in cases of hysteroscopic suspicion of malignancy.

METHODS

In this prospective clinical trial, a total of 304 consecutive women with sonographically suspected endometrial hyperplasia and/or postmenopausal bleeding, underwent D&C with intraoperative frozen section analysis between May 2013 and September 2015. Based on the results of the hysteroscopy and/or frozen section, the OSCAR-Endo score was reported: negative, when no frozen section was regarded necessary or the frozen section yielded a negative result; equivocal, when the frozen section reported an equivocal result; positive, when frozen section reported either complex hyperplasia with atypia or cancer.

RESULTS

Frozen sections were required by the surgeons in 59 (19.4%) of cases. When compared with the final histology after D&C, frozen section showed a sensitivity, specificity, PPV, NPV, and overall test accuracy of 91.3, 100, 100, 94.1, and 96.3% for predicting malignant disease, respectively. The OSCAR-Endo score showed a sensitivity, specificity, PPV, NPV, and overall test accuracy of 84, 100, 100, 98.6, and 98.7% for predicting malignant disease, respectively.

CONCLUSION

The OSCAR-Endo protocol is easy to perform in daily clinical practice reaching an excellent test accuracy. It helps in immediate postoperative counseling of affected patients. Clinical Trial Registration http://www.clinicaltrials.gov ; NCT01961102.

Comparison of cytogenetics and molecular karyotyping for chromosome testing of miscarriage specimens

OBJECTIVE

To compare chromosome testing of miscarriage specimens between traditional cytogenetic analysis and molecular karyotyping using single nucleotide polymorphism microarrays (SNP) and array comparative genomic hybridization (aCGH).

DESIGN

Prospective blinded cohort study.

SETTING

University-based practice.

PATIENT(S)

Women undergoing dilation and curettage for first-trimester miscarriage between March 2014 and December 2015.

INTERVENTION(S)

None.

MAIN OUTCOME MEASURE(S)

Chromosome analysis from chorionic villi separated equally and submitted for cytogenetics, SNP microarray, and aCGH testing.

RESULT(S)

Sixty samples were analyzed, of which 47 (78%) were chromosomally abnormal. A correct call was defined when a result was concordant with at least one other testing platform. The correct call rate was 85%, 93%, and 85% using cytogenetics, SNP array, and aCGH, respectively. We found a 33% overall discordance rate between results. Discordances were due to maternal cell contamination, balanced chromosome rearrangements, polyploidy, and placental mosaicism. Mosaicism was detected in 18% of all samples. Growth failure occurred in four samples sent to cytogenetics, of which three were chromosomally abnormal by molecular testing.

CONCLUSION(S)

This study demonstrates the many technical limitations of the three testing modalities. Our rates of maternal cell contamination were low, but it is important to note that this is a commonly reported limitation of cytogenetics. Given the similar overall performance of the three testing modalities, providers may choose a method based on individual availability and consideration of limitations as it applies to each clinical scenario. The unexpected high rate of placental mosaicism warrants further investigation.

Hysteroscopy combined dilatation and curettage, serum CA125 and CA19-9 play an important role in preserving fertility or endocrine function for early-stage endometrial cancer patients

OBJECTIVE

The aim of the study was to evaluate the role of hysteroscopy combined dilatation and curettage (D&C), serum CA125 and CA19-9 in endometrial cancer (EC) patients who desire to preserve fertility or endocrine function.

MATERIALS AND METHODS

This retrospective study included a total of 622 patients with EC between January 2006 and December 2014. The consistency of preoperative and postoperative histopathological findings were compared in patients who underwent D&C with or without hysteroscopy. The incidence of positive peritoneal cytology was also compared to assess the safety of hysteroscopy. Receiver operating characteristic (ROC) curve was used to evaluate the role of preoperative serum CA125 and CA19-9 in predicting extrauterine metastasis.

RESULTS

In 151 patients who underwent hysteroscopy combined D&C, the consistency of pre- and postoperative pathology was higher than the remaining 447 patients who underwent classical D&C alone (83.44% vs. 74.94%,p < 0.05) and there was no significant difference in the incidence of positive peritoneal cytology between the two groups (2.64% vs. 2.73%, p > 0.05). ROC curve analysis results showed the CA125 serum level of 31.75 U/ml and CA19-9 serum level of 35.40 U/ml were the best cutoff to predict extrauterine metastasis in endometrial cancer, with 66.7% sensitivity, 83% specificity, and 61.9% sensitivity and 84.9% of specificity, respectively.

CONCLUSIONS

Hysteroscopy combined D&C should be recommended for early-stage EC patients who desire to preserve fertility or endocrine function, and the preoperative serum levels of CA125 and CA19-9 were powerful in predicting tumor stage in these patients.

Direct uterine sampling using the SAP-l sampler device to detect endometrial lesions during histopathological examination

AIMS

To evaluate the sampling adequacy and diagnostic accuracy of the endometrial SAP-l sampling device in detecting endometrial lesions based on histopathological examination.

MATERIALS AND METHODS

In total, 182 patients who required an endometrial biopsy were enrolled in this study. All of the patients underwent endometrial biopsies with the SAP-l sampler prior to hysteroscopy (169/182) or dilatation and curettage (D&C) (13/182). Endometrial tissues were obtained at biopsy for histopathological examination.

RESULTS

Ad- equate endometrial specimens were obtained in 148 of 182 patients (81.32%). Menopause (p = 0.000), endometrial thickness (p = 0.004), and the types of endometrial diseases (p = 0.009) differed significantly between the two groups. Among the 169 patients who underwent hysteroscopy, sampling scratches were observed in the uterine cavity in 147 cases (86.98%). Compared to traditional methods, such as hysteroscopy and D&C, the sampling diagnostic sensitivity, specificity, and positive and negative predictive values were 82.35%, 100%, 100% , and 97.76% for endometrial carcinoma (n=17) and 37.5%, 100%, 100% and 97.76% for endometrial atypical hyperplasia (n=8), respectively. Those that were misdiagnosed occurred because the lesions were focal or localized in a small part of the uterine cavity. The sampling diagnostic sensitivity for polyps (n=32) was 12.5%. Two patients with submucosal leiomyoma went undiagnosed based on the sample specimens.

CONCLUSION

Endometrial sampling using the SAP-l sampler is a minimally invasive altemative technique for obtaining adequate endometrial specimens for histopathological examination. The SAP-l sampler was useful in detecting endometrial carcinoma and atypical hyperplasia cases that were not highly suspected to be localized; however, this method was not useful in detecting endometrial polyps and submucosal leiomyomas.

[Anesthetic Management of a Patient with Double Outlet Right Ventricle and Situs Inversus for Dilatation and Curettage of the Uterus]

A 30-year-old woman with a double outlet right ven- tricle and situs inversus was scheduled for dilatation and curettage of the uterus. We selected intravenous anesthesia which allowed spontaneous respiration, because of the short operation time and the low invasive surgery. We administered dexmedetomidine hydrochloride 1.1 μg · kg⁻¹ · hr⁻¹ and fentanyl (total amount 150 μg, three doses of 50 μg each) during operation. We accomplished anesthesia without appar- ent hemodynamic change or respiratory depression. We should select anesthetic method and anesthetic cautiously, considering patient's state.

[Evaluation of Anesthesia Method to Minimize Intraoperative Body Movement and Respiratory Depression for Dilatation and Curettage A Retrospective Study]

BACKGROUND

The optimal level of anesthesia and the dose of the agent to procure the least intraoperative body movement and respiratory depression have not been evaluated in dilatation of the cervix and curettage of the uterus (D & C).

METHODS

Sixty-eight patients were divided to one of the three groups. Group S: the use of sevoflurane (1-2%) [n=22]. Group 2.5 K: high dose (1.6-2.5 mg · kg(-1) of ketamine with fentanyl (50-100 μg) and midazolam (2 mg) [n=23]. Group 1.5 K: the standard dosage of ketamine (0.5-1.5 mg · kg(-1) with fentanyl (50-100 μg) and midazolam (2 mg) [n=23]. Patient's intraoperative body movement and the necessity of jaw-lift and assisted manual ventilation were evaluated.

RESULTS

Intraoperative body movement was significantly higher in Group 1.5 than in Groups S or 2.5 K (P<0.05). Necessity of jaw-lift and assisted manual ventilation was significantly higher in Group S than in Groups 1.5 K or 2.5 K (P<0.05).

CONCLUSIONS

Intravenous anesthesia using increasing doses of ketamine (1.6-2.5 mg · kg(-1) with fentanyl (50-100 μg) and midazolam (2 mg) reduces the intraoperative body movement without exacerbating respiratory depression during D&C.

Accuracy of hysteroscopic biopsy, compared to dilation and curettage, as a predictor of final pathology in patients with endometrial cancer

OBJECTIVE

To compare the methods of transcervical resectoscopy versus dilation and curettage (D&C) for endometrial biopsy and to compare these methods for the percentage of histological upgrades at the final posthysterectomy pathology findings in endometrial cancer.

MATERIALS AND METHODS

We retrospectively reviewed 253 cases of uterine cancer diagnosed from May 1995 to January 2014. Included in the study were patients who received transcervical resectoscopy (TCR) or D&C biopsy as the diagnostic method and underwent laparoscopic staging at our institution. The International Federation of Gynecologists and Obstetricians (FIGO) grade in the pathological report of the biopsy and final hysterectomy were recorded. The extrauterine risk was stratified using the initial FIGO grade and depth of myometrium invasion. It was compared to the actual risk using final pathological findings.

RESULTS

We identified 203 cases of endometrial cancer; 18 (8.9%) patients had a higher histological grade at the final hysterectomy. Among the 203 patients, 76 patients underwent TCR biopsy and 127 underwent D&C biopsy. The histological grade was upgraded in two (2.6%) patients in the TCR group. Three (3.9%) patients had positive peritoneal washings. In the D&C group, 16 (12.6%) patients with three (2.4%) positive peritoneal washings were upgraded.

CONCLUSION

Transcervical resectoscopy could provide more precise grading information, compared to D&C (2.6% vs. 12.6%). Doctors could therefore make a more accurate staging plan, based on the preoperative risk evaluation.

Comparison of the histopathological results of the endometrial thickness detected by transvaginal ultrasound of symptomatic and asymptomatic postmenopausal women

OBJECTIVE

The purpose of the study was to assess the reliability of transvaginal ultrasound (TVUSG) in endometrial pathologies by comparing the ultrasonographic and histopathologic findings in symptomatic and asymptomatic postmenopausal women.

MATERIALS AND METHODS

In this retrospective study the data of 129 postmenopausal women that underwent dilatation and curettage was reviewed by dividing them two groups as symptomatic and asymptomatic. Symptomatic group was divided into subgroups according to the value of endometrial thickness obtained by TVUSG.

RESULTS

Among all subjects the cancer rate was found statistically 3.043 times higher in patients with the endometrial thickness of 15 mm and greater and atrophic endometrium rate was 75% in patients with the endometrial thickness of less than five mm. Endometrial thickness was found significantly higher in cancer patients than the others (p < 0.05). Among the patients with endometrial thickness of 15 mm and greater, the cancer rate was found higher in symptomatic group than in the asymptomatic group. The cancer rate was found statistically higher in patients with bleeding compared to asymptomatic ones with the endometrial thickness between 5-14.99 mm (p < 0.05). Cancer was not detected in any of the symptomatic patients with the endometrial thickness of less than five mm.

CONCLUSION

Postmenopausal patients with the symptom of bleeding should undergo detailed gynecological and ultrasonographic examination. The authors believe that this study may be a strong support to the success of TVUSG as a screening method in both symptomatic and asymptomatic postmenopausal women. Furthermore if the patient is symptomatic with a thick endometrium, to exclude the malignancy, endometrial biopsy must be performed.

The impact of uterine curettage postpartum on maternal sFlt-1 concentration

Our purpose was to investigate the influence of a uterine curettage on the immediate maternal sFlt-1 concentration post partum. Forty-six patients booked for delivery via primary caesarean section were included in a prospective open, case control study. Eighteen of them achieved an intraoperative curettage and formed the treatment group, 28 patients without curettage were enrolled in the control group. Maternal sFlt-1 serum values were measured immediately before and 24 h after delivery. Patients who underwent a uterine curettage showed a relative decrease of 70% (median 3670±1110 pg/mL-1143±270 pg/mL) in comparison to the control group with 65% (median 3132±636 pg/mL-1098±611 pg/mL; P=0.558). Additionally, three patients with preeclampsia and curettage were included, who showed a relative decrease of 76%. A uterine curettage may slightly accelerate the fall of the postpartal sFlt-1 concentration. The previously described benefit of curettage in patients with preeclampsia regarding faster recovery or treatment of postpartum seizures may be partly explained as mediated by anti-angiogenic factors.

The effect of medical versus surgical treatment of spontaneous miscarriage on subsequent in vitro fertilization cycles

OBJECTIVE

To evaluate the effect of dilation and curettage (D&C) and misoprostol as treatments for spontaneous miscarriage (SM) on in vitro fertilization (IVF) parameters in the subsequent IVF cycle.

DESIGN

Multicenter, retrospective, cohort study. Women treated for SM after IVF treatment with D&C or misoprostol and underwent a subsequent IVF cycle was included. The main outcome measures were ovarian response, endometrial thickness and pregnancy rate in the subsequent IVF cycle after MA.

RESULTS

Among 73 patients with miscarriage, 41 had D&C and 32 were given misoprostol. Baseline serum follicle stimulating hormone (FSH) levels and ovarian responses before and after treatment of miscarriage were comparable. No significant differences were observed between the D&C and the misoprostol groups in basal FSH levels, endometrial thickness and parameters of ovarian response in the subsequent IVF cycle.

CONCLUSION

D&C and misoprostol are both effective treatments for IVF patients with miscarriage, without an adverse effect on subsequent IVF treatment outcome.

Detection and correlation of pre-operative, frozen section, and final pathology in high-risk endometrial cancer

PURPOSE

To evaluate sensitivity and specificity of pre-operative and frozen section pathologic evaluation (FSA) in predicting high-risk (HR) histology endometrial cancer.

MATERIALS AND METHODS

A retrospective analysis was performed on all patients diagnosed with endometrial cancer at a single institution. Medical records were abstracted for baseline characteristics, surgical reports for staging, and final histology was confirmed by a gynecologic pathologist.

RESULTS

868 patients were identified. Of these, 118 had Grade 3 endometrioid, 36 clear cell carcinoma (CCC), 47 carcinosarcoma (CS), and 84 uterine papillary serous carcinoma (UPSC) histology. Endometrial biopsy (EMB) had an overall sensitivity of 90%, 77% for low grade, 78% for HR, with a specificity of 0%. For dilation and curettage (D&C), overall sensitivity was 85%, 69% for low grade, and 77% for HR. Specificity was 33%. Sensitivities for combined pre-operative testing for G3 endometrioid, CCC, CS, and UPSC were: 56%, 28%, 72%, and 60%, respectively. For frozen section analysis (FSA), overall sensitivity was 77%, and 67% for low and high grade. For G3 endometrioid, CCC, CS, and UPSC, sensitivities were 57%, 20%, 74%, 32%, respectively. Specificity was 95%. FSA identified an additional six patients (8%) with UPSC, CCC or CS that were pre-operatively low risk, providing an 8% improvement in sensitivity but decreased specificity.

CONCLUSIONS

Pre-operative EMB and D&C are overall very sensitive for detecting endometrial cancer; however, sensitivity decreases with HR histology. Pre-op testing will miss 28% of HR diagnoses and FSA provides an opportunity to identify some patients with UPSC, CCC, and CS. If pre-operative results suggest HR cancer, the surgeon should proceed with comprehensive surgical staging without an FSA.

[Medical termination of pregnancy by mifepristone and misoprostol - evaluation of succes rate, complications and satisfaction of patients]

OBJECTIVE

The purpose of this study was to evaluate the success rate and complications of medical termination of pregnancy up to 49 days of amenorrhea and present the outcome of our phone questionaire of satisfaction of patients.

DESIGN

Retrospective analysis.

SETTING

Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno.

METHODS

The analysis of 111 patients, who underwent medical termination of pregnancy at the Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno from 1. 6. 2014 to 30. 6. 2015 using 600 mg of mifepristone (Mifegyne) and 400 µg of misoprostol (Mispregnol). In our set of patients we monitored subjective perception of medical termination of pregnancy (pain, nausea, vomiting, satisfaction with this method) and objective process (hospitalisation, surgical intervention). The view of patients was found out by the phone questionnaire

RESULTS

Complete abortion without a surgical intervention underwent 103 patients. Nausea, pelvic pain, and intensity of bleeding were evaluated as suitable. Only 1 patient (0.9%) was hospitalised for nausea and 1 patient (0.9%) was hospitalised in case of need for an emergency curretage and transfusions. Some kind of contraception after the medical termination of pregnancy started using 98.0% of women. The satisfaction rate of this method was high - 101 patients declared themselves satisfied - 66.7% very satisfied, 24.3% rather satisfied.

CONCLUSION

Medical termination of pregnancy has good efficiency, we consider it safe with minimum side-effects and is well evaluated by patients.

Clinical experience and perception of abortion: A cross-sectional survey of gynecologists in Japan

This study describes aspects of early induced abortion from the experience and perspectives of a sample of gynecologists in Japan. The survey questionnaire data were collected from 343 gynecologists from September to October 2010. Approximately 83% of participants preferred using only dilation and curettage (D&C), and 10.4% used electric vacuum aspiration (EVA). The cost of surgical abortion was not covered by insurance. Most gynecologists used intravenous pain management during abortion. Approximately 50% of the gynecologists were opposed to introducing medical abortion in Japan.

[Feasibility of treatment of cesarean scar pregnancy with dilatation and curettage under ultrasound guidance]

OBJECTIVE

The present study sought to investigate the predictors of successful dilatation and curettage (D&C) in treatment of cesarean scar pregnancy (CSP).

METHODS

Retrospective analysis was conducted in 84 CSP patients undergoing D&C from January 2013 to December 2014. Failure was defined as D&C followed by transcatheter uterine arterial embolization due to uncontrolled hemorrhage. Sub-stratification of success group as residue group or non-residue group was performed according to the residues at the site of cesarean scar after D&C. The univariate logistic regression and linear regression were used to assess the predictors of the failure and residues. ROC curve was used to assess the cut-off values of the predictors.

RESULTS

D&C under ultrasound guidance succeeded in 75 patients (89.3%) and 36 patients had residues at the site of cesarean scar among them (48%), 9 patients failed in D&C (10.7%). High Serum human chorionic-gonadotropin (hCG), small gestation sac (GS), thin cesarean scar myometrium thickness (CSM) and low peritrophoblastic flow resistance index (RI) were risk factors of D&C failure in treatment of CSP. That serum hCG>97 006 U/L was prime predictor of failure (predictive value 100%, 95% CI 94.9%-100%). High success ratio was observed in patients with serum hCG<58 076 U/L, GS≤19 mm, CSM>2.7 mm, and RI>0.25. And days of menopause≤41 d, GS≤15 mm, CSM>3.7 mm, RI>0.4 and serum hCG<3 935 U/L were predictors of complete success of D&C. The postponed restoration of menstruation was observed in patients with residues, which did not induce amenorrhea and disappeared in 1-3 months after procedures.

CONCLUSION

Early diagnosis and treatment is associated with successful D&C in treatment of CSP. HCG, GS, CSM and RI are valuable in predicting the prognosis of D&C in treatment of CSP.

[Diagnostic value of multiply biopsies and endocervical curettage on cervical lesions]

OBJECTIVE

To investigate the value of multiply biopsies and endocervical curettage (ECC) on diagnosing cervical lesions.

METHODS

For the detection of cervical lesions, Shenzhen cervical cancer screening trial II (SHENCCAST II) program combined methods of HPV screening with liquid-based cytology (LBC), any positive indicators was then performed multiply biopsies and ECC under colopscopy. A total of 2,558 clear colposcopic images and pathological diagnoses were reviewed. To analyse the pathological results and primary screening results of the negative colopscopic images for discussing the value of multiply biopsies and ECC.

RESULTS

Overall 2,558 women's colposcopic images and sampling results were completed and validated. 69.98% (1,790/2,558) women had normal colposcopy appearances. Among them, 2.23% (40/1,790) were diagnosed as cervical intraepithelial neoplasia II or worse (CIN II+). The odds ratio of high-grade squamous intraepithelial lesion (HSIL) was 28.37 (P=0.000) and atypical squamous cell cannot exclude HSIL (ASC-H) was 15.07 (P=0.001). HPV types 16, 52, 58, 31, 33 and 18 were related to high-grade cervical lesion with the odds ratio of 3.11 (P=0.017). Hybrid capture II (HC-II) DNA test results shown that women with HPV positive were 3.58 times more risky than those of HPV negative, which was related to high-grade cervical lesion (P=0.025). Among the 2,558 women, CIN II+ detective rate from ECC were 40.7% (44/108) in older group (≥40 years) were higher than that of 19.2% (24/125) in younger group (<40 years; χ2=13.01, P=0.000). CIN II+ detective rate from multiply biopsies were 90.7% (98/108) in older group (≥40 years) were higher than that of 88.8% (111/125) in younger group (<40 years; χ2=0.24, P>0.05). The highest risky items of detecting CIN II+ were as follows: (1) HSIL or ASC-H; (2) HPV types 16, 18, 52 and 58 positive (either one); (3) HC-II HPV positive, at least 2 of the 3 items were included among 32 cases of the 40 CIN II+ with normal colposcopy appearances.

CONCLUSIONS

The results shown that only performed multi-site biopsies with abnormal colposcopy appearances may be missed some highgrade cervical lesion. For the positive indicators during screening should be performed randomly multi-sites biopsies and ECC under colopscopy, which may be helpful to reduce miss diagnosis.

Management of cesarean scar pregnancy in the second trimester: a report of three cases

BACKGROUND

A modern entity of the cesarean scar pregnancy with or without uterine dehiscence has been described and is increasing in incidence. Early diagnosis is difficult, and management in the second trimester poses a significant clinical challenge. The best options for management are unclear due to lack of data in this area.

CASES

Three women presented with cesarean scar pregnancy and underwent suction dilation and curettage (D&C) at 13, 13, and 14 weeks' gestation, respectively. One procedure was complicated by hematometra, and reevacuation was successful. The second and third cases resulted in hysterectomy due to uncontrollable hemorrhage after suction D&C, and pathology revealed pathologically adherent placenta in both cases.

CONCLUSION

Intragestational sac methotrexate has not been reported at these later gestational ages for treatment of cesarean scar.pregnancies. D&C should be used judiciously in these patients due to the high risk of complications.

[Value of hysteroscopy and dilatation and curettage in diagnosis of endometrial cancer]

OBJECTIVE

To evaluated the value of hysteroscopy and dilatation and curettage (DC) in diagnosis of endometrial cancer.

METHODS

This retrospective analysis included clinical pathologic data of 3 676 patients with endometrial cancer from Jan. 1, 2000 to Dec. 31, 2010 in hospitals of endometrial cancer prevention projects in Guangdong Province.

RESULTS

A total of 3 676 patients with endometrial cancer were divided into DC group (3 211 patients) and hysteroscopy group (465 patients). Compared to the results of pathological diagnosis, the accuracy rate between DC group and in hysteroscopy group were no statistically difference was 91.00% (2 922/3 211) vs 90.75% (422/465; χ² = 0.030, P = 0.862). The accuracy rate, sensitivity, specificity, positive predictive value and negative predictive value of cervical involvement between DC group and hysteroscopy group were 81.28% vs 86.45% (P < 0.01), 24.78% vs 23.68% (P > 0.05), 93.76% vs 98.71% (P < 0.01), 46.75% vs 78.26% (P < 0.01) and 84.95% vs 86.88% (P > 0.05), respectively. Rate of positive peritoneal cytology in DC group was 4.76% (153/3 211), and the rate was 3.23% (15/465) in hysteroscopy group, which were no statistically difference (χ² = 2.206, P = 0.137). There were no statistically difference in 5-year overall survival (91.02% vs 92.03%; χ² = 0.033, P = 0.856) and 5-year progression-free survival (89.81% vs 91.83%; χ² = 1.508, P = 0.219) between DC group and hysteroscopy group.

CONCLUSIONS

Hysteroscopy and dilatation and curettage is an effective method in diagnosis of endometrial cancer, especially hysteroscopy is better in diagnosis of cervical involvement. Hysteroscopy don't improve risks of positive peritoneal cytology and don't affect the prognosis of patients with endometrial cancer.

Pyometra in elderly post-menopausal women: a sign of malignity

PURPOSE

To describe the clinical and histopathological characteristics of 12 patients with pyometra and highlight the increased incidence of gynecological malignancy in these patients.

MATERIALS AND METHODS

The authors examined the medical records of 12 patients with pyometra, who were treated between 2009 and 2013.

RESULTS

All patients were post-menopausal, and their mean age was 70.83 ± 6.978 years (min = 61, max = 82). To remove purulent fluid via dilation and because of the probability of malignancy, three patients (25%) underwent cervical biopsy and endometrial curettage; the other nine patients (75%) underwent curettage alone, with suitable antibiotic therapy. Of the 12 patients, nine (75%) had gynecologic malignancy [(endometrial cancer, n = 5, 41.6%), (cervical cancer, n = 3, 25%), (uterine leiomyosarcoma, n = 1, 8.3%)]. In three (25%) patients, the cause of pyometra was benign pathologies, among which the most common were leiomyomas (n = 2, 66.6%).

CONCLUSION

Pyometra diagnosed during the post-menopausal period should be considered a complication caused by gynecological malignancy until proven otherwise.

Invasive mole of the uterus- a rare case diagnosed by ultrasound: a case report

Gestational trophoblastic neoplasias (GTN) are rare tumours that constitute less than 1% of all gynecological malignancies. Invasive mole is a distinct subgroup of GTN, which if not diagnosed and treated early, can result in serious complications like uterine perforation and haemoperitoneum. We present a rare case of an invasive mole of the uterus, which developed following the evacuation of a molar pregnancy. It was accurately diagnosed by transvaginal ultrasound and color Doppler, and successfully treated before any major complications could arise.

[Reservation of fertility for seventeen patients with placental site trophoblastic tumor]

OBJECTIVE

To approach the efficiency and feasibility of preserving the fertility for patients with placental site trophoblastic tumor (PSTT).

METHODS

Totally 2 086 cases of gestational trophoblastic neoplasm (GTN) patients registered in Peking Union Medical College Hospital between 1998 and 2013. Fifty-seven of them were PSTT patients, 40 cases of which suffered hysterectomy, the rest 17 PSTT patients who preserved their fertility were analyzed retrospectively. The computerized database of clinical and pathological reports was reviewed in this cohort.

RESULTS

The clinical manifestation of PSTT was not specific compared to other types of GTN. The average age of the 17 patients was 29.5 years old (range 22-39 years). The most common antecedent pregnancy was term birth (8 cases), the others were spontaneous abortion in 4 case, artificial abortion in 3 cases and molar pregnancy in 2 cases. The baseline serum β-hCG was slightly elevated and 12 patients (12/15) were less than 1 000 U/L. In this cohort, nine of the patients were in stage I, while the other eight cases were in stage III . The patients suffered conservative surgery, including dilation and curettage of uterus in 7 cases, open abdomen uterine lesion excision in 4 cases, laparoscopic uterine lesion excision in 3 cases, hysteroscopic uterine lesion excision in 1 case, and pulmonary lobectomy in 2 cases. Two of the patients didn't received chemotherapy, while the other 15 cases suffered combination chemotherapy. Compared with 40 patients who suffered hysterectomy during the same interval, fertility preservation group did not result in poor outcomes or high risk of relapse rate. Six subsequent pregnancies happened after the therapy, two of them were during their second-trimester, while four patients had healthy babies by vaginal delivery in two and cesarean section in two. The scar of the uterus was fairly well during the cesarean sections.

CONCLUSIONS

Reservation of fertility therapy could be considered in highly-selected patients for young women who strongly desired to preserve their fertility and with localized lesion. Exactitude follow-up after therapy should be recommended. Contraception should also be recommended for at least one year after the chemotherapy. Vaginal delivery could be an option for the future pregnancies.

High-intensity focused ultrasound combined with dilatation and curettage for Cesarean scar pregnancy

We describe a new technique for the management of Cesarean scar pregnancy (CSP), high-intensity focused ultrasound (HIFU) combined with dilatation and curettage (D&C), in four patients managed at our university hospital. All four had elevated serum human chorionic gonadotropin (hCG) levels and large lesions with strong peripheral color Doppler signals, indicating possible risk of profuse bleeding, and all four women wished to preserve their fertility. HIFU was performed under local anesthesia. Success of the treatment in all four cases was indicated by complete primary evacuation of the CSP and return of serum hCG to normal levels (serum hCG < 20 mIU/mL). However, one patient in whom there was a large scar defect and placental implantation underwent laparotomy to remove the trophoblastic tissue and repair the defect, although the hCG level had already returned to normal levels. HIFU, by utilizing ultrasound energy to heat tissue at a focal point, is able to stop embryonic cardiac activity and leads to a rapid reduction in serum hCG levels. Subsequent D&C under hysteroscopic guidance enables complete removal of products of conception following the HIFU procedure.

Comparison of the histopathological diagnoses of preoperative dilatation and curettage and Pipelle biopsy

PURPOSE

To evaluate the accuracy of dilatation and curettage (D&C) and Pipelle biopsy for the diagnosis of endometrial pathologies and determine whether the amount of endometrial tissue obtained using these techniques is sufficient for further histopathology of hysterectomy specimens.

MATERIALS AND METHODS

Patients undergoing hysterectomy for various indications were evaluated via Pipelle endometrial biopsy or D&C from 2009-2011. A total of 267 women were included with 78 women enrolled in the Pipelle group and 189 in the D&C group. Uterine findings were grouped as normal, hyperplasia, focal lesion, atypia, and atrophy. Histological sections from the Pipelle biopsy or D&C specimens were compared to each other and hysterectomy specimens.

RESULTS

The concordance rate between Pipelle biopsy and hysterectomy was 62% and between D&C and hysterectomy was 67%. The sensitivity of Pipelle biopsy and D&C for detecting hyperplasia was 41.7% and 45%, respectively, and for detecting atypia was 71.4% for both techniques. The sensitivity of detecting atrophic endometrial tissue was significantly higher in the D&C group at 80% compared to 37.5% in the Pipelle biopsy group (p = 0.030). All other parameters were similar in both groups.

CONCLUSION

Pipelle biopsy and D&C were equally successful for diagnosing endometrial pathologies. Neither Pipelle biopsy nor D&C was adequate for detecting focal endometrial pathologies and endometrial hyperplasia. In contrast, both techniques were sufficient for the diagnosis of atypia. The Pipelle biopsy technique is a reasonable pre-hysterectomy procedure that is more economical, less invasive, and can easily be performed in multiple clinics.

Clostridium perfringens sepsis following a molar pregnancy

Clostridium perfringens sepsis is rare since the legalization of abortion in 1973. This is a 49 year old female who developed clostridial sepsis after suction dilation and curettage for a molar pregnancy. A hysterectomy was performed after prompt recognition, and the patient survived.

Correlation discrepancies between high-grade squamous intraepithelial lesions and high-grade cervical intraepithelial neoplasia: a cytological/histological correlation study from a single-institution experience

OBJECTIVE

Previous studies have demonstrated diagnostic discrepancies for the detection of high-grade cervical intraepithelial neoplasia (CIN 2/3) from previously confirmed cytological high-grade squamous intraepithelial lesions (HSILs). The goal of this study is to investigate the possible factors which may be responsible for this diagnostic discrepancy.

STUDY DESIGN

The study included all the cytological specimens diagnosed with a HSIL by the Papanicolaou (Pap) test at Temple University Hospital (2000-2010) as well as timely follow-up cervical biopsies. The biopsy tissue types and diagnoses were subsequently categorized and analyzed.

RESULTS

Of the total 842 Pap tests with HSIL diagnosis, 96 cases (11.4%) showed non-CIN 2/3 in follow-up cervical biopsies. Among those cases, the most common biopsy diagnoses were cervicitis (27.9%) and CIN 1 (25%). Endocervical curettage (ECC) samples showed a high percentage of inadequacy for diagnosis (43.7%). Thirty-seven cases had subsequent follow-up biopsy, and CIN 2/3 was found in 15 cases. However, none of the CIN 2/3 cases was detected by ECC sampling.

CONCLUSIONS

Our study indicated that the discrepant correlation between HSIL and CIN 2/3 was most likely due to tissue sampling issues during colposcopic examination. The diagnostic value of ECC remains poor for the detection and grading of cervical intraepithelial dysplasia.

[Different methods for the diagnosis of endometrial histological comparative study]

OBJECTIVE

To evaluate the feasibility of endometrial sampler Pipelle for endometrial histologic diagnosis.

METHODS

Using prospective and self-control methods, 200 patients with endometrial biopsy firstly used Pipelle endometrial sampler for endometrial tissue, then followed by diagnostic curettage, the same pathologist evaluated the specimen quality and made the histologic diagnosis.

RESULTS

Totally 200 patients completed the observation, the specimen satisfaction of Pipelle was 93.0% (in this 200 cases, 186 cases were satisfactory), its pathological accuracy was 85.0% (in this 200 cases, 170 cases' pathological results are highly consistent with diagnostic curettage). There was no significant difference between two kinds of endometrial sampling (P > 0.05). There was no pain for patients during the Pipelle using process.

CONCLUSION

Pipelle could obtain satisfactory samples used for histological diagnosis in normal endometrium, simple hyperplasia, complex hyperplasia, atypical hyperplasia and endometrial cancer disease, because its pathological accuracy is so close to the diagnostic curettage, which may be used as a routine screening tool of endometrial diseases.

Pre-operative endometrial thinning agents before endometrial destruction for heavy menstrual bleeding

BACKGROUND

Heavy menstrual bleeding is one of the most common reasons for referral of premenopausal women to a gynaecologist. Although medical therapy is generally first line, many women eventually will require further treatment. Endometrial ablation by hysteroscopic and more recent "second-generation" devices such as balloon, radiofrequency or microwave ablation offers a day-case surgical alternative to hysterectomy. Complete endometrial destruction is one of the main determinants of treatment success. Surgery is most effective if undertaken when endometrial thickness is less than four millimeters. One option is to perform the surgery in the immediate postmenstrual phase, which is not always practical. The other option is to use hormonal agents that induce endometrial thinning pre-operatively. The most commonly evaluated agents are goserelin (a gonadotrophin-releasing hormone analogue, or GnRHa) and danazol. Other GnRH analogues and progestogens have also been studied, although fewer data are available. It has been suggested that these agents will reduce operating time, improve the intrauterine operating environment and reduce absorption of fluid used for intraoperative uterine cavity distension. They may also improve long-term outcomes, including menstrual loss and dysmenorrhoea.

OBJECTIVES

To investigate the effectiveness and safety of pre-operative endometrial thinning agents (GnRH agonists, danazol, estrogen-progestins and progestogens) versus another agent or placebo when given before endometrial destruction in premenopausal women with heavy menstrual bleeding.

The following electronic databases were searched to April 2013 for published and unpublished randomised controlled trials that met the inclusion criteria: the Menstrual Disorders and Subfertility Group (MDSG) Specialised Register of controlled trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO.Other electronic sources of trials included trial registers for ongoing and registered trials; citation indexes; conference abstracts in the Web of Knowledge; the LILACS database for trials from the Portuguese- and Spanish-speaking world; PubMed; and the OpenSIGLE database and Google for grey literature.All searches were performed in consultation with the MDSG Trials Search Co-ordinator.

SELECTION CRITERIA

Randomised controlled trials (RCTs) were included if they compared the effects of these agents with one other, or with placebo or no treatment, on relevant intraoperative and postoperative treatment outcomes. Selection of trials was carried out independently by two review authors.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for risk of bias and extracted data on surgical outcomes, effectiveness outcomes, proportion of women requiring further surgical therapy during follow-up, endometrial outcome measures, acceptability of use outcomes and quality of life. Data were analysed on an intention-to-treat basis. Dichotomous data were combined for meta-analysis with RevMan software using the Mantel-Haenszel method to estimate pooled risk ratios (RRs). Continuous data were combined for meta-analysis with RevMan software using an inverse variance method to estimate the pooled mean difference (MD) with 95% confidence interval (CI). The overall quality of evidence for the main findings was assessed with the use of GRADE working group methods.

MAIN RESULTS

Twenty studies with 1969 women were included in this review. These studies compared GnRHa, danazol and progestogens versus placebo or no treatment; GnRHa versus danazol, progestogens, GnRH antagonists or dilatation & curettage; and danazol versus progestogens. Four studies performed more than one comparison.When compared with no treatment, GnRHa used before hysteroscopic resection were associated with a higher rate of postoperative amenorrhoea at 12 months (RR 1.6, 95% CI 1.2 to 2.0, 7 RCTs, 605 women, moderate heterogeneity; I(2) = 40%) and at 24 months (RR 1.62, 95% CI 1.04 to 2.52, 2 RCTs, 357 women, no heterogeneity; I(2) = 0%), a slightly shorter duration of surgery (-3.5 minutes, 95% CI -4.7 to -2.3, 5 RCTs, 156 women, substantial heterogeneity; I(2) = 72%) and greater ease of surgery (RR 0.32, 95% CI 0.22 to 0.46, 2 RCTs, 415 women, low heterogeneity; I(2) = 4%). Postoperative dysmenorrhoea was reduced (RR 0.59, 95% CI 0.40 to 0.87, 2 RCTs, 133 women, no heterogeneity; I(2) = 0%). The use of GnRHa had no effect on intraoperative complication rates (RR 1.47, 95% CI 0.35 to 6.06, 5 RCTs, 592 women, no heterogeneity; I(2) = 0%), and participant satisfaction with this surgery was high irrespective of the use of pre-operative endometrial thinning agents (RR 0.99, 95% CI 0.93 to 1.05, 6 RCTs, 599 women, low heterogeneity; I(2) = 11%). GnRHa produced more consistent endometrial atrophy than was produced by danazol (RR 1.84, 95% CI 1.23 to 2.75, 2 RCTs, 142 women, no heterogeneity; I(2) = 0%). For other intraoperative and postoperative outcomes, any differences were minimal, and no benefits of GnRHa pretreatment were noted in studies in which women underwent second-generation ablation techniques. Both GnRHa and danazol produced side effects in a significant proportion of women, although few studies reported these in detail. Few randomised data were available to allow assessment of the effectiveness of progestogens as endometrial thinning agents. When reported, the long-term effects of endometrial thinning agents on benefits such as postoperative amenorrhoea were reduced with time.The main study weaknesses were that most participants received no follow-up beyond 24 months and that the studies used a small sample size. Heterogeneity for outcomes reported ranged from none to substantial. More than half the trials had no blinding of participants or outcome assessment. Most of the trials were determined to have uncertain selection and reporting bias, as they did not report allocation concealment and evidence of selective reporting was noted. The quality of reporting of adverse events was generally poor, but, when described in the studies, they included menopausal symptoms such as hot flushes, vaginal dryness, hirsutism, decreased libido and voice changes, as well as other side effects such as headache and weight gain.

AUTHORS' CONCLUSIONS

Low-quality evidence suggests that endometrial thinning with GnRHa and danazol before hysteroscopic surgery improves operating conditions and short-term postoperative outcomes. GnRHa produced slightly more consistent endometrial thinning than was produced by danazol, although both achieved satisfactory results. The effect of these agents on longer-term postoperative outcomes was reduced with time. No benefits of GnRHa pretreatment were apparent with second-generation ablation techniques. Also, side effects were more common when these agents were used.

Color Doppler sonography as an adjunct to repeat uterine evacuation for gestational trophoblastic disease: case report

Repeat uterine evacuation is a therapeutic option for preserving fertility in patients with gestational trophoblastic neoplasms and chemoresistance, but remains controversial due to the risks of hemorrhage and perforation. A 25-year-old patient with low-risk gestational trophoblastic neoplasm became chemoresistant; however, chemotherapy reduced intrauterine tumor vascularity as observed by color Doppler sonography, suggesting that patients could undergo uterine evacuation without major risk of bleeding. After 18 months, she achieved a normal pregnancy. Serial assessment of tumor vascularity with color Doppler sonography may provide information regarding the appropriate time to perform a repeat uterine evacuation without significant bleeding.

Postabortion care in Pakistan

The current law in Pakistan permits abortion only under narrow circumstances. As a result, women resort to clandestine and unsafe abortion procedures, which often lead to complications. This report summarizes findings from a study that examined the conditions under which women obtain abortion in Pakistan; the incidence, coverage and quality of facility-based postabortion care (PAC); and the extent to which recommended standards for PAC have been implemented in health facilities.
