Risk of Association of Placenta Praevia with History of Uterine Scar

Background: In Placenta Previa the placenta is implanted in the lower uterine segment in pregnancy with previous Caesarian Section there is risk of placenta being adherent with the scar, leading to devastating hemorrhage. The aim of this study was to find out the risk of association of placenta praevia with history of uterine scar. Methods: It was a hospital based observational cross-sectional study and was carried out in Department of Obstetrics and Gynecology. Dhaka Medical College and Hospital, Dhaka from May 2013 to October 2013. Total 50 patients were enrolled as diagnosed case of placental praevia. Patients clinical condition and course of management, perinatal outcome were observed, recorded & categorized Data were analyzed using computer with Statistical Package for Social Sciences (SPSS) software for Windows version 20. Results: This study shows commonest age group was 26-30 years, which included 46%, 36% belonged to 31-35 years age group. The average age was 29.80 years. Most (94%) of the patients were multigravida Maximum (54%) number of cases were admitted during the gestational period of 35-38 weeks. Common clinical presentations were anaemia (80%) and per vaginal bleeding (84%). Regarding management, 76% patients were managed actively and 24% patients were managed expectantly. It was observed that placenta praevia with uterine scar is seen more frequently (66%) in cases of previous caesarean sections. Among 30 patients, 84% were live births, 10% were still births and 6% were neonatal deaths. No maternal death was observed in this study. Conclusion: This study shows strong association between previous caesarean section, uterine curettage and hysterotomy and placenta praevia. Most of the patients were provided with active modality of management. Hence the study advocates the use of contraceptive, advanced antenatal care & early referral to hospital and expectant management of patients after proper selection to reduce the premature birth.

Comparation of abdominal aortic balloon occlusion versus uterine artery embolization in the treatment of cesarean scar pregnancy.

This study is to uncover the advantages of abdominal aortic balloon occlusion in the uterine curettage treatment for patients with cesarean scar pregnancy (CSP). To retrospectively analyze the clinical data of eighty patients with CSP after treatment in our hospital from 01/10/2019 to 01/05/2021. The 80 patients were divided into 2 groups: 41 patients were treated with abdominal aortic balloon occlusion and the control group (n = 39) underwent Uterine artery embolization (UAE). The amount of bleeding during the operation, the operation time of the uterine curettage, the X-ray fluoroscopy time under DSA, the surface dose in radiation, the length of hospital stay (LOS), and the postoperative complications were compared between these 2 groups (type II and type III). All the operations successfully retained the uterus. No balloon-related complications occurred in the experimental group. And in the control group, there were 14 cases of fever and 19 cases of pain after UAE. The fluoroscopy time of experimental group and control group were: (type II: (20.3 ± 7.1)s vs. (593.7 ± 284.5)s, p < 0.01), (type III: (21.2 ± 7.2)s vs. (509.8 ± 164.2)s, p < 0.01), the surface dose in radiation: (type II: (1.9 ± 0.7)mGy vs. (248.3 ± 85.9)mGy, p < 0.01), (type III: (2.1 ± 0.8)mGy vs.(252.0 ± 74.9)mGy, p < 0.01), the amount of bleeding during the operation: (type II:30.0(20.0, 50.0)ml vs. 20.0(10.0, 50.0)ml, p = 0.113), (type III:50.0 (17.5,162.5)ml vs. 50.0 (22.5, 72.5)ml, p = 0.623), the operation time of the uterine curettage:(type II: (54.8 ± 19.4)min vs.(43.9 ± 21.9)min, p = 0.071), (type III: (65.2 ± 50.4)min vs.(52.8 ± 20.1)min, p = 0.426), LOS: (type II:(5.4 ± 1.7)d vs.(5.4 ± 1.2)d, p = 0.816), (type III:(5.8 ± 2.4)d vs. (7.0 ± 1.7)d, p = 0.161). The follow-up was more than 3 months. No adverse reaction in the experimental group and 6 patients in the control group presented menstrual volume decrease. No balloon-related complications occurred in the abdominal aortic balloon occlusion and lower radiation exposure for both the operator and patient. And both abdominal aortic balloon occlusion and UAE can effectively reduce the bleeding during uterine curettage in patients with type II and III CSP.

Analysis of Fertility Prognosis and Risk Factors in Patients Post-Gestational Trophoblastic Disease.

To retrospectively analyze the fertility outcomes and prognosis of gestational trophoblastic disease (GTD) patients, providing a basis for targeted fertility guidance and counseling. 82 GTD patients of childbearing age who received treatment at the Obstetrics and Gynecology Department of Lanzhou University First Hospital from January 2016 to January 2023 were stratified into re-pregnancy (n = 20) and non-re-pregnancy (n = 33) cohorts based on their pregnancy outcomes. The impacts of various factors on pregnancy outcomes were subsequently evaluated, encompassing the rates of subsequent pregnancies, live births, miscarriages, ectopic pregnancies, and ongoing pregnancies. Finally, logistics regression model was employed to analyze the risk factors affecting re-pregnancy in GTD patients. The study delineated those patients with different GTD pathologies had varying re-pregnancy rates (mole, erosive mole and choriocarcinoma accounted for 66.04%, 30.19% and 3.77%, respectively). Treatment predominantly involved uterine curettage, with fewer cases receiving chemotherapy alone or in conjunction with curettage accounted for 67.92%, 5.66%, and 26.42%, respectively. The average chemotherapy frequency was 4.59 ± 2.43 sessions, and a majority sought reproductive counseling. Re-pregnancy occurred in 37.74% of patients. The live birth rate was 65.00%, with miscarriage and ectopic pregnancy rates at 25.00% and 5.00% respectively. Logistic regression analysis pinpointed the absence of pre-pregnancy counseling as a significant independent risk factor for re-pregnancy in GTD patients (p < 0.05). While chemotherapy may influence ovarian function, with the majority of patients desiring children post-recovery, pregnancy rates remain high. Fertility counseling significantly enhances re-pregnancy success rates in GTD survivors, emphasizing its recommendation for those aiming to conceive post-recovery.

Fertility-sparing surgical interventions for low-risk, non-metastatic gestational trophoblastic neoplasia.

The primary treatment approach for addressing low-risk nonmetastatic gestational trophoblastic neoplasia (LR-NMGTN) in women desiring fertility preservation involves chemotherapy. An alternative option for treatment is fertility-sparing surgical interventions, either alone or in combination with adjuvant chemotherapy. The hypothesised advantages of choosing fertility-sparing surgery in cases of LR-NMGTN include potential avoidance of adverse effects associated with chemotherapy, potential reduction in the number of chemotherapy cycles required to achieve complete remission, and potential reduction in time to remission. To measure the benefits and harms of fertility-sparing surgical interventions, with or without adjuvant chemotherapy, compared to primary chemotherapy alone, for the treatment of women with low-risk, non-metastatic gestational trophoblastic neoplasia (LR-NMGTN). We searched CENTRAL, MEDLINE, Embase, Web of Science, ClinicalTrials.gov and WHO ICTRP on 31 January 2024. We also searched abstracts of scientific meetings and reference lists of included studies. We included all randomised controlled trials (RCTs) comparing fertility-sparing surgical interventions, with or without subsequent adjuvant chemotherapy, versus primary chemotherapy as standard care for the treatment of women with LR-NMGTN. We employed standard Cochrane methodological procedures. We used the GRADE approach to assess the certainty of evidence for each outcome, if available. We focused on the following outcomes: treatment success rate, relapse, disease-specific mortality, death due to treatment, pregnancy rate, quality of life, and any adverse events. We included two RCTs, with a total of 151 participants contributing data to our analyses. Both studies used uterine curettage as the fertility-sparing surgical intervention. Fertility-sparing surgical intervention without subsequent adjuvant chemotherapy versus primary chemotherapy alone One RCT involving 62 participants with varying hCG (human chorionic gonadotrophin) levels evaluated this comparison. Most of our outcomes of interest were not measured in this study. The relative risk of experiencing any adverse event could not be estimated as chemotherapy adverse effects were not reported. The study reported that there were no surgical complications. Chemotherapy was administered to 50% of participants in the intervention group after curettage because their hCG levels increased. Fertility-sparing surgical intervention with subsequent adjuvant chemotherapy versus primary chemotherapy alone One RCT involving 89 participants with hCG levels < 5000 IU/L evaluated this comparison. We judged the risk of bias in the study to be high. The evidence was very uncertain about the effect of uterine curettage with subsequent adjuvant chemotherapy on treatment success rate (RR 1.03, 95% CI 0.86 to1.23; 86 participants), relapse (RR 0.5, 95% CI 0.05 to 5.31; 86 participants), pregnancy rate (RR 0.86, 95% CI 0.31 to 2.34; 86 participants), and rate of adverse events (RR 1.15, 95% CI 0.63 to 2.13; 86 participants), all very low certainty evidence. The relative risks of disease-specific mortality and death due to treatment could not be estimated as there were no deaths in either group. There were no results for quality of life as this outcome was not reported. Uterine curettage is the only fertility-sparing surgical intervention for LR-NMGTN that has been evaluated in a randomised controlled trial. The evidence is very uncertain about the benefits and harms of uterine curettage, with or without subsequent adjuvant chemotherapy, compared to primary chemotherapy alone. The two available studies are small with a high risk of bias, and future research may find substantially different results for all reported outcomes. Larger RCTs, with appropriate clinical outcome measures, would be required to determine the benefits or harms of fertility-sparing surgical interventions for this population.

Uterine Artery Embolization for Iatrogenic Uterine Vascular Injuries

Abstract Purpose Uterine curettage or surgery can lead to uterine vascular injuries such as arteriovenous malformations (AVMs) or pseudoaneurysms (PsAs), and patients may present with life-threatening uterine bleeding. The purpose of our study is to evaluate the effectiveness of uterine artery embolization (UAE) in patients with abnormal uterine bleeding due to iatrogenic vascular injuries. Methods This is a retrospective review of 22 patients who underwent UAE at our institution between January 2019 and January 2023. Sixteen patients had a history of iatrogenic procedures. Uterine curettage was done in 12 patients, manual vacuum aspiration in 1 patient, and cesarean surgery in 3 patients. The outcomes were assessed in the form of technical feasibility, cessation of bleeding, recurrence, and pregnancy on follow-up. Results Eighteen (18/22) patients had vascular malformations and 4 (4/22) had PsA on computed tomography. Eight patients had typical AVM features with early draining vein and 10 patients had hypertrophied vessels with no early draining veins. A total of 35 uterine arteries were embolized in 22 patients. The most commonly used embolic material was polyvinyl alcohol particles (28/35 arteries). Postembolization, bleeding symptoms subsided in 19 patients (86.4%). Three patients had recurrence of bleeding symptoms for which they underwent repeat embolization. Six patients (27%) became pregnant during the follow-up period of 15 months. Conclusion UAE is a safe and effective treatment for iatrogenic uterine vascular injuries. This procedure allows for the preservation of uterine function with the possibility of future pregnancy and should be considered as a primary treatment option.

Heterotopic pregnancy: a case report of intrauterine hydatidiform mole with tubal pregnancy.

We herein report a rare case of simultaneous intrauterine molar pregnancy and tubal pregnancy. A woman of childbearing age who had never been pregnant underwent an ultrasound examination 70 days after the onset of menopause. She had a history of ovulation induction. The ultrasound findings suggested a partial hydatidiform mole. She was then pathologically confirmed to have a complete hydatidiform mole after uterine suction dilation and curettage. On postoperative day 4, an ultrasound examination before discharge showed an inhomogeneous mass in the left adnexal region with mild lower abdominal pain. On postoperative day 17, the blood human chorionic gonadotropin level did not drop as expected, and a follow-up examination still indicated a mass in the left adnexal region. We were unable to rule out an ectopic hydatidiform mole. Hysteroscopy with laparoscopic exploration of the left adnexal mass and salpingotomy suggested a diagnosis of intrauterine hydatidiform mole combined with left tubal pregnancy.

MSCs promote the efferocytosis of large peritoneal macrophages to eliminate ferroptotic monocytes/macrophages in the injured endometria.

Endometria are one of the important components of the uterus, which is located in the peritoneal cavity. Endometrial injury usually leads to intrauterine adhesions (IUA), accompanied by inflammation and cell death. We previously reported that both the endometrial ferroptosis was increased and monocytes/macrophages were involved in endometrial injury of IUA. Large peritoneal macrophages (LPMs) are recently reported to migrate into the injured tissues and phagocytose dead cells to repair the tissues. We previously demonstrated that mesenchymal stromal cells (MSCs) had made excellent progress in the repair of endometrial injury. However, it is unclear whether MSCs regulate the LPM efferocytosis against ferroptotic monocytes/macrophages in the injured endometria. Here, endometrial injury in IUA mouse model was conducted by uterine curettage and LPS injection surgery and the samples were collected at different times to detect the changes of LPMs and ferroptotic monocytes/macrophages. We conducted LPMs depletion assay in vivo and LPMs and Erastin-induced ferroptotic THP-1 cells coculture systems in vitro to detect the LPM efferocytosis against ferroptotic monocytes/macrophages. The IUA model was treated with MSCs, and their effects on LPMs and endometrial repair were analyzed. Flow cytometry, western blotting, quantitative real-time PCR, immunohistochemical analysis, ELISA, and RNA-sequencing were performed. We found that LPMs migrated to the injured uteri in response to the damage in early phase (3h), and sustained to a later stage (7 days). Astonishingly, we found that ferroptotic monocytes/macrophages were significantly increased in the injured uteri since 12h after injury. Moreover, LPMs cocultured with Erastin-induced ferroptotic THP-1 cells in vitro, efferocytosis of LPMs against ferroptotic monocytes/macrophages was emerged. The mRNA expression profiles revealed that LPM efferocytosis against ferroptotic monocytes/macrophages was an induction of glycolysis program and depended on the PPARγ-HK2 pathway. Importantly, we validated that MSCs promoted the efferocytic capability and migration of LPMs to the injured uteri via secreting stanniocalcin-1 (STC-1). The data collectively demonstrated first the roles of LPMs via removal of ferroptotic monocytes/macrophages and provided a novel mechanism of MSCs in repairing the endometrial injury.

Analysis of CDO1, PITX2, and CDH13 Gene Methylation in Early Endometrial Cancer for Prediction of Medical Treatment Outcomes.

To determine CDO1, PITX2, and CDH13 gene methylation levels in early endometrial cancer and atypical hyperplasia specimens obtained before organ-preserving treatment in the patients with adequate response and with insufficient response to hormonal treatment. A total of 41 endometrial specimens obtained during diagnostic uterine curettage in women with EC (n = 28) and AEH (n = 13), willing to preserve reproductive function, were studied; 18 specimens of uterine cancer IA stage G1 from peri- and early postmenopausal women (comparison group) were included in the study. The control group included 18 endometrial specimens from healthy women obtained by diagnostic curettage for missed abortion and/or intrauterine adhesions. Methylation levels were analyzed using the modified MS-HRM method. All 13 women with AEH had a complete response (CR) to medical treatment. In the group undergoing organ-preserving treatment for uterine cancer IA stage G1 (n = 28), 14 patients had a complete response (EC CR group) and 14 did not (EC non-CR group). It was found that all groups had statistically significant differences in CDO1 gene methylation levels compared to the control group (p < 0.001) except for the EC CR group (p = 0.21). The p-value for the difference between EC CR and EC non-CR groups was <0.001. The differences in PITX2 gene methylation levels between the control and study groups were also significantly different (p < 0.001), except for the AEH group (p = 0.21). For the difference between EC CR and EC non-CR groups, the p-value was 0.43. For CDH13 gene methylation levels, statistically significant differences were found between the control and EC non-CR groups (p < 0.001), and the control and EC comparison groups (p = 0.005). When comparing the EC CR group with EC non-CR group, the p-value for this gene was <0.001. The simultaneous assessment of CDO1 and CDH13 genes methylation allowed for an accurate distinction between EC CR and EC non-CR groups (AUC = 0.96). The assessment of CDO1 and CDH13 gene methylation in endometrial specimens from patients with endometrial cancer (IA stage G1), scheduled for medical treatment, can predict the treatment outcome.

Janus adhesive microneedle patch loaded with exosomes for intrauterine adhesion treatment.

Intrauterine adhesions (IUAs) are common sequelae of cervical mucosa damage caused by uterine curettage. Establishing an anti-adhesion barrier between the damaged endometrium with a sustained-release drug capability and hence promoting endogenous regeneration of the endometrium is an available treatment for IUA. However, current therapy lacks long-term intracavitary residence, drug-delivery permeability, and tissue anti-adhesion to the endometrium. Here, we report the design of a Janus microneedle patch consisting of two layers: an adhesive inner layer with an exosomes-loaded microneedle, which endows the patch with a tissue adhesive capability as well as transdermal drug-delivery capability; and an anti-adhesion outer layer, which prevents the intrauterine membrane from postoperative adhesion. This Janus adhesive microneedle patch firmly adhered to uterine tissue, and sustainedly released ∼80% of the total loaded exosomes in 7 days, hence promoting the expression of vascular- and endothelial-related cell signals. Furthermore, the anti-adhesive layer of the microneedle patch exhibited low cell and protein adhesion performance. In rats, the microneedle patch successfully prevented uterine adhesions, improved endometrial angiogenesis, proliferation, and hormone response levels. This study provides a stable anti-adhesion barrier as well as efficient drug-release capability treatment for intrauterine adhesion treatment.

Analysis of uterine evacuation methods in postabortion care after implementation of a surveillance network (CLAP MUSA-Network) at a university hospital

Background Management of uterine evacuation is essential for increasing safe abortion care. Monitoring through surveillance systems tracks changes in clinical practice and provides information to improve equity in abortion care quality. Objective This study aimed to evaluate the frequency of manual vacuum aspiration (MVA) and medical abortion (MA), and identify the factors associated with each uterine evacuation method after surveillance network installation at a Brazilian hospital. Methods This cross-sectional study included women admitted for abortion or miscarriage to the University of Campinas Women’s Hospital, Brazil, between July 2017 and November 2020. The dependent variables were the use of MVA and MA with misoprostol. The independent variables were the patients’ clinical and sociodemographic data. The Cochran–Armitage, chi-square, and Mann–Whitney U tests, as well as multiple logistic regression analysis, were used to compare uterine evacuation methods. Results We enrolled 474 women in the study, 91.35% of whom underwent uterine evacuation via uterine curettage (78.75%), MVA (9.46%), or MA (11.54%). MVA use increased during the study period (Z = 9.85, p &lt; 0.001). Admission in 2020 (odds ratio [OR] 64.22; 95% confidence interval [CI] 3.79–1086.69) and lower gestational age (OR 0.837; 95% CI 0.724–0.967) were independently associated with MVA, whereas the only factor independently associated with MA was a higher education level (OR 2.66; 95% CI 1.30–5.46). Conclusion MVA use increased following the installation of a surveillance network for good clinical practice. Being part of a network that encourages the use of evidence-based methods provides an opportunity for healthcare facilities to increase access to safe abortions.

РАЗРЫВ НЕОПЕРИРОВАННОЙ МАТКИ В ПЕРВОЙ ПОЛОВИНЕ БЕРЕМЕННОСТИ: КЛИНИЧЕСКОЕ НАБЛЮДЕНИЕ

Abstract. Introduction. Uterine rupture is a rare and life-threatening complication for patient and fetus. This pathology is mostly associated with pregnancy and occurs in late preterm periods, but there are also some cases of non-pregnant uterus ruptures described. Aim. This study is aimed at showing and analyzing the importance of uterine ruptures, even without any uterine scars and in the first half of pregnancy. Materials and Methods. This paper describes the clinical case of a multigravida patient with the rupture of unscarred uterus in the second trimester of pregnancy. Results and Discussion. A 32-year-old female patient was admitted to the department of gynecology at the gestational age of 16 weeks, complaining of severe abdominal pains, with the signs of intraabdominal bleeding. Histopathic rupture of the uterus was detected in the emergency laparotomy. Conclusions. Absence of uterine scars does not prevent from potential rupture of the uterus Timely diagnosis is necessary, and an emergency surgical intervention must be performed to save the patient’s life at any suspicion on uterine rupture. Even with early pregnancies, uterine rupture risks must be considered, especially regarding women with a history of uterine cavity surgeries. There is a question of the necessity to perform elective hysteroscopy during pregnancy planning to patients with the past history of uterine curettage

The incidence, indications, risk factors and pregnancy outcomes of peripartum hysterectomy at a tertiary hospital between 2013 and 2022.

To analyze the incidence, indications, risk factors and pregnancy outcomes of postpartum hemorrhage resulting in peripartum hysterectomy (PH). We retrospectively reviewed patients with postpartum hemorrhage requiring surgical procedures at ≥ 28weeks of gestation from January 1, 2013 to December 31, 2022 at a tertiary hospital in Shanghai, China. The patients were divided into a PH group and a non-PH group. Maternal clinical characteristics, the management of postpartum hemorrhage, pregnancy outcomes were compared between groups. Logistic regression was used to analyze the correlations between risk factors and PH. The incidence of hysterectomy was 0.2/1000 deliveries (31/150194). The variables significantly associated with PH were placenta previa with placenta increta/percreta (OR36.26), uterine rupture (OR266.16) and an estimated blood loss ≥ 3513mL (OR431.11). The proportion of cases involving hemorrhagic shock, disseminated intravascular coagulation, bladder injury, neonatal severe asphyxia, neonatal death and hypoxic-ischemic encephalopathy were significantly higher in the PH group (P < 0.05). The most common indications of PH were placental pathology. Efforts should be made to reduce the rate of cesarean deliveries and uterine curettage to lower the probability of abnormal placental invasion and appropriate medical indications for trial of labor after cesarean should be strictly followed to avoid the risk of uterine rupture.

Risk factors for postpartum haemorrhage in women with histologically verified placenta accreta spectrum disorders: a retrospective single-centre cross-sectional study

BackgroundPlacenta accreta spectrum (PAS) disorders have been reported with an increasing frequency of up to 3%. The increase in the incidence can be explained by the rising rate of Caesarean section (CS), assisted reproductive technology (ART) and previous uterine surgeries. PAS disorders are usually associated with postpartum haemorrhage (PPH). In our study, we investigated the risk factors for increased blood loss in women with histologically verified PAS disorders independent of delivery mode.MethodsIn a retrospective single-centre cross-sectional study, 2,223 pregnant women with histologically verified PAS disorders were included. Risk factors for PPH in women with PAS disorders were examined and compared between women with PPH (study group; n = 879) and women with normal blood loss (control group; n = 1150), independent of delivery mode. PAS disorders were diagnosed histologically from the following specimens: placenta, placental-bed specimens, uterine curettage, uterine resection and/or total/partial hysterectomy. Medical data were extracted from clinical records of pregnant women with PAS disorders delivering at the University Hospital Basel between 1986 and 2019. The placenta data of women with PAS disorders were obtained and identified through a search from the database of the Department of Pathology, University Hospital Basel.ResultsBetween 1986 and 2019, there were 64,472 deliveries at the University Hospital Basel. PAS disorders were histologically verified in 2,223 women (2,223/64,472), and the prevalence of PAS disorders was 3.45%. A total of 879 women with PAS disorders showed PPH, independent of delivery mode (43.3%). Due to missing data for 194 women, the final analysis was conducted with the remaining 2,029 women. Placenta praevia (O.R. = 6.087; 95% CI, 3.813 to 9.778), previous endometritis (O.R. = 3.011; 95% CI, 1.060 to 9.018), previous manual placenta removal (O.R. = 2.530; 95% CI, 1.700 to 3.796), ART (O.R. = 2.169; 95% CI, 1.593 to 2.960) and vaginal operative birth (O.R. = 1.715; 95% CI, 1.225–2.428) can be considered important risk factors, and previous CS (O.R. = 1.408; 95% CI, 1.016 to 1.950) can be considered a moderate potential risk factor of PPH in women with PAS disorders.ConclusionsPlacenta praevia, previous endometritis, previous placenta removal, ART and vaginal operative birth can be considered important risk factors of PPH in women with PAS disorders.Study registrationThe study was registered under http://www.ClinicalTrials.gov (NCT05542043) on 15 September 2022.

The rationale for the choice of preventive intraoperative anesthesia for uterine curettage in patients with individual intolerance to amide anesthetics

Background. Uterine curettage (UC) is widely used in global clinical practice owing to its great diagnostic and therapeutic value. At the same time, UC leads to a damage to the integrity of soft tissues, causing development of postoperative pain syndrome. Some patients have an individual intolerance to amide anesthetics, which limits their use in this cohort. Purpose: to improve the quality of providing anesthetic care in the early postoperative period after UC to women who have a history of individual intolerance to amide anesthetics through selection of a comprehensive method of preventive intraoperative anesthesia for this category of patients. Materials and methods. Ninety females took part in the study. Clinical, laboratory, and mathematical and statistical research methods were used to study the preventive analgesic effectiveness of the compared methods of anesthesia. Five samples of biological material, called the control points, were taken: before surgery, immediately after it, then 1, 3 and 6 hours after intervention. In this way, an idea was got about the initial level of the studied indicators and their changes during the postoperative stay in the hospital. Properties of various combinations of propofol, ketamine, fentanyl, and dexketoprofen were studied. Results. It was revealed that a combination of propofol (2 mg/kg), fentanyl (0.1 µg/kg), ketamine (0.1 mg/kg), as well as additional intravenous administration of dexketoprofen (50 mg) at the stage of premedication has the advantages in terms of preventive intraoperative analgesia. Effectiveness of the proposed method of anesthesia was proved by significantly better indicators of vital functions (heart rate, mean arterial pressure) and serum levels of some laboratory markers of stress (glucose, cortisol, insulin, cortisol-insulin index). Differences in the studied parameters were recorded both when comparing them between the groups at the same control time points and conside-ring the development and regression of the postoperative pain syndrome severity within the groups. Conclusions. The proposed method of anesthesia has a reliable advantage in terms of preventive reduction of the postoperative pain syndrome of UC in patients who cannot have application anesthesia due to individual intolerance to amide drugs. The specified method has a positive effect on vital functions and serum levels of some laboratory markers of stress, and the fastest recovery of patients is caused by a lower suppressive action of the anesthetic drugs used.

Transvaginal Ultrasound Evaluation Of Cesarean Section Niche Scar During Pregnancy: A Prospective Longitudinal Study

Background and Objectives: To determine the prevalence of a CS scar niche during pregnancy using transvaginal ultrasound imaging, and to determine the relationship between the evolution of the CS scar niche and the ultimate pregnancy result. Materials and Methods: Transvaginal sonography was used in this prospective observational research to look at the uterine scars of 100 women at 11+0-13+6, 18+0-20+6 and 32+0-35+6 weeks of pregnancy. When the region of hypoechogenic myometrial discontinuity of the lower uterine section was discovered, a scar was discernible while pregnant. An indentation at the location of the CS scar with a depth of at least 2 mm in the sagittal axis was designated as the CS scar niche (or "defect"). Myometrial thickness next to the niche and the remaining myometrial thickness were used to quantify the hypoechogenic portion of the CS niche in two dimensions. (RMT). The entire lower uterine segment (LUS) thickness and the myometrial layer thickness were measured during the second and third trimesters of pregnancy at the thinnest portion of the scar area. In a non-selected subset of patients (n=20), CS scars were measured by two separate examiners. Scar visibility was evaluated using descriptive analysis, and the intraclass correlation coefficient (ICC) was computed to demonstrate the degree of absolute agreement between two observers for measuring scars. Maternal age, BMI, smoking status, prior vaginal deliveries, obstetric complications, and a history of uterine curettage were among the factors looked into as potential contributors to the CS scar niche. The hospital's computerized medical database provided clinical statistics on pregnancy outcomes and complications. Results: 80.9% of the ladies could see the scar. A CS scar niche was prevalent in 53.6% of people with a noticeable CS scar. Excellent intra- and interobserver agreement was observed for CS scar niche readings. There was no statistically significant correlation between maternal age, BMI, gestational diabetes, smoking status, previous vaginal delivery after CS, and niche development when subgroups of women were compared in terms of CS scar niche and non-niche. In contrast to 34.4 % of the women who did not have uterine curettage, 56.3% of the women who had done uterine curettage had uterine scar niches. Conclusions: The CS scar niche could be reproducibly measured by a transvaginal scan in half of the cases with a visible CS scar at the first trimester of pregnancy, according to an ultrasonography evaluation. An increased chance of uterine niche formation in a subsequent pregnancy was linked to prior uterine curettage. The CS scar area may be connected to uterine scar dehiscence.

Vaginal Approach to Cesarean Section Scar Pregnancies: A Standardized 10-step Surgical Procedure

To show a 10-step standardized vaginal surgical technique to treat first trimester C-Section scar pregnancies. Video Article with a stepwise demonstration captured in an Operation Room of a tertiary medical center of a Low-Income country (Bolivia). C-Section scar pregnancies have a wide variety of management options. We present a vaginal surgical approach which has been developed by our group with no observed complications in 6 consecutive cases at the time of this publication. Ten-Step technique: 1.- Patient positioning, 2.- Cervical exposure and traction, 3.- Cervical infiltration with vasoconstrictor solution. 4.- Anterior mucosal incision and dissection of vesicovaginal space, 5.- Identification of vascular pedicle and ligation, 6.- Cold-Knife isthmocele incision and ectopic pregnancy evacuation, 7.- Uterine cavity curettage, 8.- Hysterorraphy with interrupted suture, 9.- Cystoscopy, 10.- Vaginal mucosa closure with running suture. We have used this technique in 6 consecutive patients. Operating time ranged between 20 - 25 minutes. All patients were discharged in postoperative day 1. We prefer surgical options for these patients since it provides both a complete removal of the ectopic pregnancy and repair of the isthmocele. A vaginal approach to such cases has proven to be a safe, simple and fully reproductible technique. We find it applicable for any patient with this pathology but especially suitable for low resource or somehow financially challenged hospitals.

Development and validation of a nomogram to predict spontaneous preterm birth in singleton gestation with short cervix and no history of spontaneous preterm birth

BackgroundSpontaneous preterm birth (sPTB) stands as a leading cause of neonatal mortality. Consequently, preventing sPTB has emerged as a paramount concern in healthcare. Therefore, our study aimed to develop a nomogram, encompassing patient characteristics and cervical elastography, to predict sPTB in singleton pregnancies. Specifically, we targeted those with a short cervix length (CL), no history of sPTB, and who were receiving vaginal progesterone therapy. MethodsA total of 568 patients were included in this study. Data from 392 patients, collected between January 2016 and October 2019, constituted the training cohort. Meanwhile, records from 176 patients, spanning November 2019 to January 2022, formed the validation cohort. Following the univariate logistic regression analysis, variables exhibiting a P-value less than 0.05 were integrated into a multivariable logistic regression analysis. The primary objective of this subsequent analysis was to identify the independent predictors linked to sPTB in the training cohort. Next, we formulated a nomogram utilizing the identified independent predictors. This tool was designed to estimate the likelihood of sPTB in singleton pregnancies, particularly those with a short CL, devoid of any sPTB history, and undergoing vaginal progesterone therapy. The C-index, Hosmer-Lemeshow (HL) test, calibration curves, decision curve analysis (DCA), and receiver operating characteristic (ROC) were used to validate the performance of the nomogram. ResultsUpon finalizing the univariate analysis, we progressed to a multivariable analysis, integrating 8 variables with P < 0.05 from the univariate analysis. The multivariable analysis identified 7 independent risk factors: maternal age (OR = 1.072; P < 0.001), cervical length (OR = 0.854; P < 0.001), uterine curettage (OR = 7.208; P < 0.001), GDM (OR = 3.570; P = 0.006), HDP (OR = 4.661; P = 0.003), C-reactive protein (OR = 1.138; P < 0.001), and strain of AI (OR = 7.985; P < 0.001). The nomogram, tailored for sPTB prediction, was grounded on these 7 independent predictors. In predicting sPTB, the C-indices manifested as 0.873 (95% CI, 0.827–0.918) for the training cohort and 0.916 (95%CI, 0.870–0.962) for the validation cohorts, underscoring a good discrimination of the model. Additionally, the ROC curves served to evaluate the discrimination of nomogram model across both cohorts. Calibration curves were delineated, revealing no statistically significant differences in both the training (χ2 = 5.355; P = 0.719) and validation (χ2 = 2.708; P = 0.951) cohorts as evidenced by the HL tests. Furthermore, the DCA underscored the model's excellence as a predictive tool for sPTB. ConclusionsBy amalgamating patient characteristics and cervical elastography data from the second trimester, the nomogram emerged as a visually intuitive and dependable tool for predicting sPTB. Its relevance was particularly pronounced for singleton pregnancies characterized by a short CL, an absence of prior sPTB incidents, and those receiving vaginal progesterone therapy.

Efficacy and Safety of the Surgery-First Approach Compared to the Chemotherapy-First Approach for Treating Low-Risk Gestational Trophoblastic Neoplasia: A Systematic Review and Meta-Analysis.

For gestational trophoblastic neoplasia (GTN) affecting women of reproductive age, the chemotherapy-first approach is often preferred over the surgery-first approach. Low-risk GTN is treated with a chemotherapy-first approach, but the number of courses required can affect fertility. A surgery-first approach may decrease the number of chemotherapy courses, but its efficacy and safety compared to a chemotherapy-first approach are unclear. Thus, we investigated the efficacy and safety of the surgery-first approach compared to the chemotherapy-first approach in treating low-risk GTN. We searched the MEDLINE, Embase, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform databases for relevant articles in July 2023. A systematic review and meta-analysis of outcome measures were conducted using a random-effects model. The primary outcomes were remission, the mean number of chemotherapy courses required to cure, and adverse events. The certainty of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation approach. This study protocol was registered in the Open Science Framework (https://osf.io/kysvn/). Studies for low-risk GTN included a qualitative synthesis (with 2,192 participants and ten studies, eight of which were about second uterine curettage and two about hysterectomy) and a meta-analysis (with 138 participants and two randomized controlled trials (RCTs) that compared first-line treatments of second uterine curettage and chemotherapy). Second uterine curettage may result in little to no difference in remission (risk ratio: 1.00, 95% confidence interval: 0.96-1.05; low certainty) and a slight reduction in adverse events (risk ratio: 0.87, 95% confidence interval: 0.47-1.60; low certainty). The evidence is very uncertain on the mean number of chemotherapy courses (mean difference: 2.84 lower, 95% confidence interval: 7.31 lower to 1.63 higher; very low certainty). Based on clinical outcomes, second uterine curettage can be comparable to the chemotherapy-first approach as a first-line treatment option for low-risk GTN; however, the overall certainty of the evidence was low or very low.

The readmission of a parturient with natural delivery after discharge due to residual fetal membrane: A case report.

Placental residue is a relatively common and sophisticated disease among obstetric delivery complications. A failure to detect placental residue in time may cause poor outcomes such as postpartum hemorrhage and puerperal infection. We present the case of a 33-year-old full-term singleton parturient with placental residue. Upon precipitate labor and childbirth, the placenta and fetal membranes were examined to be intact. However, 1 day after discharge, she felt that there was discharge from the vagina and thus presented to our emergency department. The patient was diagnosed with residual membranes and readmitted to the hospital for uterine curettage. Uterine curettage was performed under B-ultrasound guidance. The patient was discharged smoothly without any postoperative complications. This paper can provide significant enlightenment for the prevention and early treatment of placental residue, including enhancing the risk awareness of high-risk patients, standardizing the process of clinical examination of the placenta, and early uterine contraction promotion to assist in the discharge of residual tissue, so as to reduce the occurrence of placental residue.

Transvaginal Evisceration Following Uterine Perforation by Abortion Procedure: About a Case Treated at the Reference Health Center of Commune 1 of Bamako

We report a case of bowel evisceration following uterine perforation after an abortive manoeuvre by unqualified personnel. After the procedure, there was abundant vaginal bleeding and a complication was encountered: small bowel evisceration approximately 1 metre long via the vagina, certainly following the seizure of these small bowels and their successive traction which led first to the uterine cavity, then the vagina and finally to the vulva. Given the author's fear, the patient was referred urgently for treatment. After a transfusion of two units of blood and a triple laparotomy, a 1 m resection of the small intestine with end-to-end anastomosis was performed; suture of the uterine perforation and curettage of the cavity. The patient was discharged from the centre 10 days after surgery. Conclusion: This case shows the clandestine nature of induced abortions, which are responsible for multiple complications, including visceral lesions and uterine perforations.
