Surgical treatment and reproductive outcomes in caesarean scar pregnancy at a single center.

BACKGROUND: To investigate factors associated with different reproductive outcomes in patients with Caesarean scar pregnancies (CSPs). METHODS: Between May 2017 and July 2022, 549 patients underwent ultrasound-guided uterine aspiration and laparoscopic scar repair at the Gynaecology Department of Hubei Maternal and Child Health Hospital. Ultrasound-guided uterine aspiration was performed in patients with type I and II CSPs, and laparoscopic scar repair was performed in patients with type III CSP. The reproductive outcomes of 100 patients with fertility needs were followed up and compared between the groups. RESULTS: Of 100 patients, 43% had live births (43/100), 19% had abortions (19/100), 38% had secondary infertility (38/100), 15% had recurrent CSPs (RCSPs) (15/100). The reproductive outcomes of patients with CSPs after surgical treatment were not correlated with age, body mass index, time of gestation, yields, abortions, Caesarean sections, length of hospital stay, weeks of menopause during treatment, maximum diameter of the gestational sac, thickness of the remaining muscle layer of the uterine scar, type of CSP, surgical method, uterine artery embolisation during treatment, major bleeding, or presence of uterine adhesions after surgery. Abortion after treatment was the only risk factor affecting RCSPs (odds ratio 11.25, 95% confidence interval, 3.302-38.325; P < 0.01) and it had a certain predictive value for RCSP occurrence (area under the curve, 0.741). CONCLUSIONS: The recurrence probability of CSPs was low, and women with childbearing intentions after CSPs should be encouraged to become pregnant again. Abortion after CSP is a risk factor for RCSP. No significant difference in reproductive outcomes was observed between the patients who underwent ultrasound-guided uterine aspiration and those who underwent laparoscopic scar repair for CSP.

A combination of laparoscopy and bilateral uterine artery occlusion for the treatment of type II cesarean scar pregnancy: a retrospective analysis.

OBJECTIVE: We investigated the efficacy of a combination of laparoscopy and bilateral uterine artery occlusion (BUAO) for the treatment of type II cesarean scar pregnancy (CSP). METHODS: Patients with type II CSP underwent laparoscopy + bilateral uterine artery embolization (control group) or laparoscopy + BUAO (study group). Data regarding the duration of surgery, intraoperative hemorrhage, postoperative complications, the duration of the hospital stay, and the costs of hospitalization were retrospectively collected. One year later, the time to the return of the ß-human chorionic gonadotropin (ß-hCG) concentration to normal and to the return of menstruation were compared. RESULTS: The duration of surgery, time to the return of menstruation, and incidence of postoperative complications in the study group were significantly less than in the control group, but there was no significant difference in the time for ß-hCG to return to normal or the volume of intraoperative hemorrhage. The duration of hospitalization and costs for the control group were higher than those for the study group. CONCLUSION: Laparoscopy in combination with BUAO is associated with minimal trauma, rapid recovery, a short duration of surgery, low cost of hospitalization, and a low postoperative complication rate. Thus, it represents a useful new surgical treatment for type II CSP.

Advances in Treating Cesarean Scar Pregnancy: A Comprehensive Review of Techniques, Clinical Outcomes, and Fertility Preservation.

Cesarean scar pregnancy (CSP) is a rare but potentially dangerous condition that occurs when an embryo implants and develops within the scar tissue from a previous cesarean section. Treatment of cesarean scar pregnancy depends on several factors, including the gestational age of the pregnancy, the presence of complications, and the individual patient's circumstances. We performed a systematic review of the published literature on management of cesarean scar pregnancy and the outcomes, complications, and effects on fertility. A systematic review of recent scientific literature published up to April 2023 in the databases PubMed, Google Scholar, and Web of Science was performed according to the PRISMA guidelines. We used the search keywords "cesarean scar pregnancy," "methotrexate," "systemic," "chemoembolization," and "uterine artery embolization." The baseline search resulted in 413 articles. After the exclusion of 342 irrelevant articles, the abstracts and titles of the remaining 71 articles were read for potential inclusion, resulting in exclusion of a further 16 articles. Therefore, the full texts of 55 articles were investigated. Finally, 42 papers were included in the study. The main finding was that chemoembolization is more successful than systemic methotrexate therapy, and is associated with less blood loss and shorter hospital stay. Transarterial chemoembolization appears to be safe and effective method of treatment in patients with CSP and should thus be considered during multidisciplinary evaluation of these patients.

Early intrauterine pregnancy with an intrauterine device in place and terminated with spontaneous abortion: A case report.

RATIONALE: The overall pregnancy rate in individuals with an intrauterine device (IUD) for contraception is <1%. If pregnancy occurs while an IUD is in place, there is a higher risk of an ectopic pregnancy. We report the case of a woman with an IUD who was 7 weeks pregnant and experienced a spontaneous abortion 1 week later. PATIENT CONCERN: A 32-year-old woman presented to our outpatient department with intermittent vaginal staining for several days. DIAGNOSES: She was 7 weeks pregnant and had an IUD in place for over 4 years. A vaginal examination revealed no vaginal bleeding and no blood clots; however, a parous cervix was observed. The IUD string was not visible. Transvaginal ultrasonography revealed a gestational sac in the uterine cavity, with a fetal pole and a crown-rump length of 11.4 mm. The fetal heart rate was 159 beats/min. The IUD was located in the retroplacental region. The bilateral adnexa appeared normal (right ovary, 2.9 cm; left ovary, 2.5 cm). The patient was diagnosed with an intrauterine pregnancy with an IUD in place and threatened abortion. INTERVENTIONS: Attempts to remove the IUD were abandoned due to its location, and conservative treatment was initiated with Utrogestan (100 mg) administered 3 times a day for 1 week. Bed rest was advised. OUTCOMES: Unfortunately, she experienced a complete abortion 1 week later. LESSONS: The novelty of this case report lies in the rare occurrence of an intrauterine pregnancy with a long-term IUD in place, the challenges posed by the IUD's specific location, and the complex management of threatened abortion in this context. Our case highlights the diagnostic management approach for intrauterine pregnancy with an IUD in place. Furthermore, it explores the impact of IUD location on pregnancy prognosis.

Study on the optimal time limit of frozen embryo transfer and the effect of a long-term frozen embryo on pregnancy outcome.

In this retrospective study conducted at Sichuan Jinxin Xinan Women and Children's Hospital spanning January 2015 to December 2021, our objective was to investigate the impact of embryo cryopreservation duration on outcomes in frozen embryo transfer. Participants, totaling 47,006 cycles, were classified into 3 groups based on cryopreservation duration: ≤1 year (Group 1), 1 to 6 years (Group 2), and ≥6 years (Group 3). Employing various statistical analyses, including 1-way ANOVA, Kruskal-Wallis test, chi-square test, and a generalized estimating equation model, we rigorously adjusted for confounding factors. Primary outcomes encompassed clinical pregnancy rate and Live Birth Rate (LBR), while secondary outcomes included biochemical pregnancy rate, multiple pregnancy rate, ectopic pregnancy rate, early and late miscarriage rates, preterm birth rate, neonatal birth weight, weeks at birth, and newborn sex. Patient distribution across cryopreservation duration groups was as follows: Group 1 (40,461 cycles), Group 2 (6337 cycles), and Group 3 (208 cycles). Postcontrolling for confounding factors, Group 1 exhibited a decreased likelihood of achieving biochemical pregnancy rate, clinical pregnancy rate, and LBR (OR < 1, aOR < 1, P < .05). Furthermore, an elevated incidence of ectopic pregnancy was observed (OR > 1, aOR > 1), notably significant after 6 years of freezing time [aOR = 4.141, 95% confidence intervals (1.013-16.921), P = .05]. Cryopreservation exceeding 1 year was associated with an increased risk of early miscarriage and preterm birth (OR > 1, aOR > 1). No statistically significant differences were observed in birth weight or sex between groups. However, male infant birth rates were consistently higher than those of female infants across all groups. In conclusion, favorable pregnancy outcomes align with embryo cryopreservation durations within 1 year, while freezing for more than 1 year may diminish clinical pregnancy and LBRs, concurrently elevating the risk of ectopic pregnancy and preterm birth.

Dilatation and Curettage after Uterine Artery Embolization versus Methotrexate Injection for the Treatment of Cesarean Scar Pregnancy: A Single-Center Experience.

Background and Objectives: Cesarean scar pregnancy (CSP) represents a type of ectopic pregnancy in which the embryo implants inside the scar of a previous cesarean section. This condition can lead to maternal morbidity and mortality. The best therapeutic approach in terms of clinical effectiveness and patient safety for CSP has not been described yet, although different therapeutic strategies are currently available. The purpose of the present study was to analyze the success rate of two different treatments in a single institution. Materials and Methods: A retrospective study was performed among patients diagnosed with CSP at the Gynecology and Obstetrics Department of the "Cannizzaro" Hospital in Catania (University of Enna-Italy) from January 2016 to December 2022. The diagnosis was made by 2D/3D transvaginal ultrasound, following Timor-Tritsch criteria. Two treatment strategies were performed: local and systemic methotrexate (MTX) injection and uterine artery embolization (UAE) with subsequent dilatation and curettage (D&C). All treated women underwent subsequent clinical and sonographic follow-up. Complete recovery was defined as the reduction of ß-HCG values until it was undetectable and the disappearance of the mass in the uterine scar on ultrasound. Results: Nineteen patients were included; nine were in the MTX group and ten were in the UAE + D&C group. No significant differences were found between the two groups in terms of clinical parameters. Treatment was successful in 4 of 10 (44%) patients in the MTX group and 10 of 10 (100%) in the UAE + D&C group (p = 0.01); the length of hospital stay was significantly shorter in the latter group (p < 0.0001). Conclusions: In our experience, administration of MTX is not recommended as the primary treatment or pre-treatment. Dilatation and curettage after uterine artery embolization are better than methotrexate injection for the treatment of cesarean scar pregnancy in a single-institution series in terms of complete recovery and length of hospital stay.

Differential Diagnostic Value of Two-dimensional Ultrasound Combined with Three-dimensional Ultrasound Imaging Technology for Cesarean Scar Pregnancy.

BACKGROUND: Cesarean scar pregnancy (CSP) refers to the phenomenon in which a fertilized egg implants and develops in the scar of the uterus in a woman with a history of cesarean section. OBJECTIVE: The study aimed to explore the differential diagnostic value of two-dimensional ultrasound (2D US) combined with three-dimensional ultrasound (3D US) for CSP. METHODS: Clinical data of 89 patients with CSP admitted to our hospital from January 2022 to January 2023 were retrospectively analyzed. Of them, 65 patients met the inclusion criteria. Patients underwent 2D US, 3D US, and combined 2D and 3D US imaging. Using the clinical pathological diagnosis as the "gold standard", the differential diagnostic value of 2D US, 3D US, and 2D US combined with 3D US for CSP was compared. RESULTS: The detection rate of CSP using a combined 2D US and 3D US was 98.46%, which was higher than 84.62% and 89.23% achieved with 2D US and 3D US alone, respectively (P<0.05). The pathological results showed that among 65 patients, CSP type I accounted for 24.62%, type II accounted for 55.38%, and type III accounted for 20.00%. The coincidence rate of 2D US combined with 3D US was 98.46%, which was higher than that of 2D US (83.08%) and 3D US 89.23%) alone (P<0.05). The accuracy, specificity, and sensitivity of 2D US combined with 3D US in diagnosing CSP were higher compared to the two methods alone (P<0.05). CONCLUSION: The combination of 2D US and 3D US can accurately detect and classify CSP, further improving diagnostic efficiency.

The effectiveness of hysteroscopy for the treatment of cesarean scar pregnancy: a retrospective cohort study.

BACKGROUND: Cesarean scar pregnancy (CSP) is a long-term complication of cesarean section characterized by the localization of a subsequent gestational sac within the scar area or niche developed as a result of a previous cesarean section. Its incidence has increased substantially because of the high global cesarean section rate in recent decades. Several surgical and drug treatments exist for this condition; however, there is currently no optimal treatment. This study compared the effectiveness of direct hysteroscopic removal of the gestational tissue and hysteroscopy combined with vacuum suction for the treatment of CSP. METHODS: From 2017 to 2023, 521 patients were diagnosed with CSP at our hospital. Of these patients, 45 underwent hysteroscopy. Among them, 28 underwent direct hysteroscopic removal (hysteroscopic removal group) and 17 underwent hysteroscopy combined with vacuum suction (hysteroscopic suction group). The clinical characteristics and outcomes of the hysteroscopic removal group and hysteroscopic suction group were analyzed. RESULTS: Among the 45 patients, the amount of bleeding and hospitalization cost were significantly higher in the hysteroscopic removal group than in the hysteroscopic suction group (33.8 mL vs. 9.9 mL, P < 0.001; and 8744.0 yuan vs. 5473.8 yuan, P < 0.001; respectively). The operation time and duration of hospitalization were significantly longer in the hysteroscopic removal group than in the hysteroscopic suction group (61.4 min vs. 28.2 min, P < 0.001; and 3.8 days vs. 2.4 days, P = 0.026; respectively). Three patients in the hysteroscopic removal group had uterine perforation and received laparoscopic repair during operation. No complications occurred in the hysteroscopic suction group. One patient in the hysteroscopic removal group received ultrasound-guided suction curettage due to postoperative moderate vaginal bleeding, and one patient in the hysteroscopic suction group received ultrasound-guided suction curettage due to postoperative gestational residue and elevated serum beta-human chorionic gonadotropin levels. Reproductive function was preserved in all patients. CONCLUSIONS: Hysteroscopy is an effective method for treating CSP. Compared with direct hysteroscopic removal, hysteroscopy combined with vacuum suction is more suitable for CSP. However, multicenter prospective studies with large sample sizes are required for verification of these findings.

Unusual presentation of late-stage ectopic tubal pregnancy (19 weeks' gestation): Case report and literature review.

Ectopic pregnancy is a medical condition in which a fertilized egg takes an unexpected detour away from the uterine cavity and the fallopian tube becomes a popular host, with the ampulla being the prime location. However, it can occur in other areas such as cervix, ovaries, or abdomen. The most common risk factors are pelvic inflammatory disease, previous pelvic or abdominal surgery, abnormal anatomy of genital organs, endometriosis, previous ectopic pregnancies, assisted reproductive technologies, endocrine disorders, and even the subtle influence of low-dose progestins from contraceptives. We will present a rare case of unrecognized late-stage tubal ectopic pregnancy. The following case report is of a 25-year-old Caucasian female patient (G2, P0) who presented to the emergency department with a 24-hour abdominal pain syndrome. The patient did not have a gynecological examination for this reason. During the examination, taking into account the clinical and ultrasound findings, a suspicion of pregnancy in a bicornuate uterus was raised, and an MRI of the pelvis was performed. MRI showed ectopic pregnancy in the left fallopian tube with a properly developed fetus that corresponded to a gestation of 19 weeks. An emergency laparotomy was performed and the left fallopian tube with the fetus was removed. The early and late course of recovery went smoothly. The patient was discharged after adequate clinical development.

Sequential embryo transfer combined with intrauterine perfusion improved pregnancy outcomes in patients with recurrent implantation failure.

OBJECTIVE: To compare the application of sequential embryo transfer, cleavage embryo transfer, and blastocyst transfer combined with intrauterine perfusion in frozen-thawed embryo transfer cycles in patients with recurrent implantation failure to provide a reference for reproductive clinicians. METHODS: The 166 patients who underwent frozen-thawed embryo transfer due to recurrent implantation failure in the reproductive center from January 2021 to March 2022 were retrospectively analyzed. According to the different embryos transferred, they were divided into cleavage embryo transfer groups (72 cases in Group A), blastocyst transfer group (29 cases in Group B), and sequential transfer group (65 cases in Group C). All three groups were treated with intrauterine perfusion 5 days before embryo transfer. The general data and clinical pregnancy outcome indicators, such as embryo implantation rate, clinical pregnancy rate, ongoing pregnancy rate, live birth rate, twin rate, were compared among the three groups. RESULTS: The embryo implantation rate (53.1%), clinical pregnancy rate (76.9%), ongoing pregnancy rate (67.7%) and live birth rate(66.15%) in the sequential transfer group were significantly higher than those in the other two groups (P < 0.05), and the ectopic pregnancy rate was lower in the sequential transfer group. CONCLUSION: Sequential transfer combined with intrauterine perfusion partially improves clinical pregnancy outcomes and reduces the risk of ectopic pregnancy in frozen embryo cycle transfers in patients with recurrent implantation failure, which may be a favourable transfer reference strategy for patients with recurrent implantation failure.

The body mass index and the risk of ectopic pregnancy: a 5-year retrospective case-control study.

PURPOSE: Acknowledging the associated risk factors may have a positive impact on reducing the incidence of ectopic pregnancy (EP). In recent years, body mass index (BMI) has been mentioned in research. However, few studies are available and controversial on the relationship between EP and BMI. METHODS: We retrospectively studied the EP women as a case group and the deliveries as a control group in the central hospital of Wuhan during 2017 ~ 2021. χ2 test of variables associated with ectopic pregnancy was performed to find differences. Univariate and multivariate binary logistic regression analysis was conducted to analyze the association of the variables of age, parity, history of induced abortion, history of ectopic pregnancy, history of spontaneous abortion, history of appendectomy surgery and BMI (< 18.5 kg/m2, 18.5 ~ 24.9 kg/m2, 25 kg/m2 ~ 29.9 kg/m2, ≥ 30 kg /m2) with EP. RESULTS: They were 659 EP and 1460 deliveries. The variables of age, parity, history of induced abortion, history of ectopic pregnancy and BMI were different significantly(P < 0.05). Multivariate analysis showed that the variables of age > 35 years old [(OR (Odds Ratio), 5.415; 95%CI (Confidence Interval), 4.006 ~ 7.320, P < 0.001], history of ectopic pregnancy (OR, 3.944; 95%CI, 2.405 ~ 6.467; P < 0.001), history of induced abortion(OR, 3.365; 95%CI, 2.724 ~ 4.158, P < 0.001) and low BMI (< 18.5 kg/m2) (OR, 1.929; 95%CI, 1.416 ~ 2.628, P < 0.001])increased the risk of EP. CONCLUSION: The history of ectopic pregnancy, history of induced abortion and age > 35 years old were the risk factors with EP. In addition to these traditional factors, we found low BMI (< 18.5 kg/m2) with women may increase the risk to EP.

Ultrasound-guided suction curettage followed by cervico-isthmic placement of foley threeway catheter for cesarean scar pregnancy's treatment. Retrospective study.

OBJECTIVES: Cesarean scar pregnancy (CSP) is a rare dangerous condition with still no consensus on standard treatment. Suction curettage has been used as the first-line treatment for CSP with controversial outcomes. This study evaluates efficacy of ultrasound-guided suction curettage (UGSC) followed by cervical-isthmic placement of silicon semirigid three-way foley catheter. MATERIALS AND METHODS: This study included 24 women with CSP. Preoperative ultrasound study was conducted. UGSC followed by placement of catheter was performed in all patients. The success rate and incidence of major complication, surgical time and hospital stay were recorded. RESULTS: The success rate of UGSC followed by placement of foley catheter was 100 %, effectively reduced major complications and none of the patients had a blood loss higher than 900 ml. Median hospital stay was 2 days and median foley stay was 1 day. Surgery had limited last with a median of 17 min. CONCLUSION: UGSC followed by foley placement is a safe effective treatment for CSP with a clinical resolution of 100 %. The catheter is easy to place under ultrasound guidance and prevents bleeding, reducing major procedures to solve the bleeding. Suction curettage in CSP treatment should be performed under ultrasound guidance and followed by cervical-isthmic placement of foley balloon.

Predicting intraoperative hemorrhage during curettage treatment of cesarean scar pregnancy using free-breathing GRASP DCE-MRI.

OBJECTIVE: To explore the feasibility of the golden-angle radial sparse parallel (GRASP) dynamic magnetic resonance imaging (MRI) technique in predicting the intraoperative bleeding risk of scar pregnancy. METHODS: A total of 49 patients with cesarean scar pregnancy (CSP) who underwent curettage and GRASP-MRI imaging were retrospectively selected between January 2021 and July 2022. The pharmacokinetic parameters, including Wash-in, Wash-out, time to peck (TTP), initial area under the curve (iAUC), the transfer rate constant (Ktrans), constant flow rate (Kep), and volume of extracellular space (Ve), were calculated. The amount of intraoperative bleeding was recorded by a gynecologist who performed surgery, after which patients were divided into non-hemorrhage (blood loss ≤ 200 mL) and hemorrhage (blood loss > 200 mL) groups. The measured pharmacokinetic parameters were statistically compared using the t-test or Mann-Whitney U test with a significant level set to be p < 0.05. The receiver operating characteristic (ROC) curve was constructed, and the area under the curve (AUC) was calculated to evaluate each parameter's capability in intraoperative hemorrhage subgroup classification. RESULTS: Twenty patients had intraoperative hemorrhage (blood loss > 200 mL) during curettage. The hemorrhage group had larger Wash-in, iAUC, Ktrans, Ve, and shorter TTP than the non-hemorrhage group (all P > 0.05). Wash-in had the highest AUC value (0.90), while Ktrans had the lowest value (0.67). Wash-out and Kep were not significantly different between the two groups. CONCLUSION: GRASP DCE-MRI has the potential to forecast intraoperative hemorrhage during curettage treatment of CSP, with Wash-in exhibiting the highest predictive performance. This data holds promise for advancing personalized treatment. However, further study is required to compare its effectiveness with other risk factors identified through anatomical MRI and ultrasound.

Risk factors of ectopic pregnancy after in vitro fertilization-embryo transfer in Chinese population: A meta-analysis.

BACKGROUND: The prevalence of ectopic pregnancy after assisted reproduction is notably high, posing a significant threat to the life safety of pregnant women. Discrepancies in published results and the lack of a comprehensive description of all risk factors have led to ongoing uncertainties concerning ectopic pregnancy after assisted reproduction. OBJECTIVE: This study aimed to understand the risk factors for ectopic pregnancy after in vitro fertilization-embryo transfer in the Chinese population and provide a reference for targeted prevention and treatment. METHODS: A comprehensive search of the China National Knowledge Infrastructure, Wang fang Database, China Science Technology Journal Database, Chinese Biomedical Literature Database, PubMed, Web of Science, and Embase was conducted to identify relevant literature on the risk factors for ectopic pregnancy in Chinese women after assisted reproductive technology in Chinese women. A meta-analysis of the included studies was performed using Stata17. RESULTS: Overall, 34 articles were included in the analysis. The risk factors for ectopic pregnancy after in vitro fertilization-embryo transfer in the Chinese population included a thin endometrium on the day of HCG administration and embryo transplantation, a history of ectopic pregnancy, secondary infertility, a history of induced abortion, polycystic ovary syndrome, decreased ovarian reserve, tubal factor infertility, cleavage stage embryo transfer, fresh embryo transfer, artificial cycle protocols, elevated estradiol levels on the day of human chorionic gonadotropin administration, a history of tubal surgery, two or more number of embryo transfers, previous pregnancy history, and a history of pelvic surgery. CONCLUSION: This study clarified the factors influencing ectopic pregnancy after in vitro fertilization and embryo transfer in the Chinese population, focusing on high-risk groups. Targeted and personalized intervention measures should be adopted to prevent and detect the disease early to reduce its incidence and harm. TRIAL REGISTRATION: The protocol for this view was registered in PROSPERO (CRD42023414710).

Findings from the Use of Spinal Anesthesia in the Laparoscopic Treatment of Extrauterine Pregnancy: Could It Represent an Alternative to General Anesthesia?

INTRODUCTION: Minimally invasive procedures performed in laparoscopy, such as salpingectomy for ectopic pregnancy, can be combined with a minimally invasive anesthesia. The aim of this study was to assess the feasibility and the intraoperative and postoperative outcomes of laparoscopic surgery for ectopic pregnancy under spinal anesthesia (SA) compared to general anesthesia (GA) from the point of view of the surgeon, anesthesiologist, and patient. METHODS: A retrospective cohort study was performed at DAI Materno Infantile of AOU Federico II of Naples, analyzing all medical records of women who met the inclusion criteria between April 2020 and April 2023. Eighty-two women (35 under SA in group A and 47 under GA in group B) undergone elective or emergency laparoscopic salpingectomy for ectopic tubal or ovarian pregnancy were included. RESULTS: Patients in group A reported less pain at 0 h (adjusted mean difference: -1.5; 95% CI: -2.3 to -0.7; p < 0.001) and after 6 h (adjusted mean difference: -1.1; 95% CI: -2.0 to -0.3; p = 0.01) while no statistically significant differences between the two groups at 12 and 24 h after surgery. No differences were observed among the type of analgesic and during the postoperative observation time, except for paracetamol at 0 h in group B. A faster resumption of bowel motility, patient's mobilization, and a shorter hospital stay were observed in group A compared to group B. Also greater odds of returning faster to daily activities emerged in group A (adjusted OR: 5.39; 95% CI: 1.77-16.37). A greater number of patients in group A were satisfied with the entire procedure compared to those of group B (33 [94.3%] vs. 37 [78.7%]). The general surgeon satisfaction was always very good or excellent in group A. Finally, all surgical steps were well tolerated in group A. CONCLUSION: In specific settings, SA is a feasible and safe procedure for the laparoscopic treatment of ectopic pregnancy.

Predictive value of crossover sign for outcome of ultrasound-guided vacuum aspiration in women with Cesarean scar pregnancy.

OBJECTIVE: To examine the value of the crossover sign (COS) in predicting treatment outcome in women with a Cesarean scar pregnancy (CSP) who were treated with ultrasound-guided vacuum aspiration. METHODS: This was a retrospective cohort study of women with CSP who underwent ultrasound-guided vacuum aspiration. Based on the relationship between the gestational sac, Cesarean scar and anterior wall of the uterus, CSPs were classified by COS type. Analysis was conducted to investigate the association between COS type (COS-1, COS-2) and treatment outcome. The incidence of treatment failure, retained pregnancy tissue, secondary therapy and bleeding ≥ 200 mL were analyzed. RESULTS: In total, 181 eligible patients with CSP, including 90 (49.7%) women with COS-1 and 91 (50.3%) women with COS-2, were analyzed. COS-1 patients had a higher incidence of treatment failure compared with COS-2 patients (25.6% vs 8.8%; P = 0.003), as well as higher rates of retained pregnancy tissue (18.9% vs 6.6%; P = 0.013), secondary therapy (20.0% vs 6.6%; P = 0.002) and bleeding of ≥ 200 mL (13.3% vs 4.4%; P = 0.034). COS-1 and a large gestational sac (30.1-50.0 mm or >50.0 mm in diameter) were associated independently with increased risk of treatment failure (odds ratio, 4.57 (95% CI, 1.66-12.56); P = 0.003, 4.34 (95% CI, 1.35-13.94); P = 0.014 and 10.50 (95% CI, 2.54-43.46); P = 0.001, respectively). CONCLUSIONS: Ultrasound evaluation of the relationship between the gestational sac and the endometrial line (COS classification) in women with CSP may help to predict treatment outcome among those undergoing vacuum aspiration. Among COS-1 patients, especially those with a gestational sac diameter of >30.0 mm, vacuum aspiration may be discouraged. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Evaluation of Cesarean section scar using saline contrast sonohysterography in women with previous Cesarean scar pregnancy.

OBJECTIVE: To evaluate Cesarean scar defects using saline contrast sonohysterography (SCSH) in women with a history of Cesarean scar pregnancy (CSP). METHODS: A cohort of 38 non-pregnant women with a history of CSP treated with combined local and systemic methotrexate was investigated prospectively by SCSH. For the purpose of analysis, they were classified, according to the modified Delphi consensus criteria for CSP in early gestation, into three subgroups based on the depth of the gestational sac herniation in the midsagittal plane. Subgroup A included eight (21.1%) cases, in which the largest part of the gestational sac protruded towards the uterine cavity; Subgroup B included 20 (52.6%) cases, in which the largest part of the gestational sac was embedded in the myometrium; and Subgroup C included 10 (26.3%) cases, in which the gestational sac was located partially outside the outer contour of the cervix or uterus. RESULTS: SCSH revealed that all women in Subgroup C had a uterine niche. The median niche length (P = 0.006) and depth (P = 0.015) were significantly greater in Subgroup C than in Subgroups A or B. The median residual myometrial thickness (RMT) was significantly lower in Subgroup C than in Subgroups A or B (P = 0.006). CONCLUSIONS: Women with prior CSP who had a gestational sac protruding beyond the serosal line had a significantly greater niche length and depth, and lower RMT. This knowledge may guide individualized risk counseling. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

Caesarean scar ectopic pregnancy: A case series.

Caesarean scar ectopic pregnancy (CSEP) is a uncommon presentation of pregnancy with incidence of nearly 1 in 2000 pregnancies. We present this case series of scar pregnancy with a objective to help obstetricians in early diagnosis and appropriate management to prevent its catastrophic complications.

Diagnostic value of enhanced-contrast ultrasound for cesarean scar pregnancy: A systematic review.

BACKGROUND: Cesarean scar pregnancy, an uncommon ectopic pregnancy in which the embryo is implanted in the cesarean scar, poses significant risks without prompt diagnosis and treatment. Its prevalence has risen alongside increased cesarean section rates. Despite various treatment approaches, consensus remains elusive. Ultrasonography, particularly contrast-enhanced ultrasonography, shows promise in cesarean scar pregnancy diagnosis. MAIN BODY: This systematic review, following PRISMA guidelines, explores contrast-enhanced ultrasound's diagnostic potential in cesarean scar pregnancy. We searched PubMed, Scopus, Web of Science, and Google Scholar up to August 2023. Selection involved two stages: title/abstract screening and full-text assessment. The included studies investigated contrast-enhanced ultrasound's diagnostic value in cesarean scar pregnancy, provided adequate data, and were peer-reviewed in English. Quality assessment followed the QUADAS-2 criteria. We extracted the diagnostic accuracy metrics: sensitivity, specificity, and accuracy. Out of 193 records, five studies met the inclusion criteria (2016-2020, China). Contrast-enhanced ultrasound displayed sensitivities of 77%-100% and specificities of 95%-100%. Two studies reported accuracy of 96.9%-97.8%. Compared with conventional ultrasound, contrast-enhanced ultrasound exhibited superior sensitivity, specificity, and accuracy. It also outperformed transvaginal ultrasound. CONCLUSION: Enhanced-contrast ultrasound holds promise for diagnosing and managing cesarean scar pregnancy by visualizing scar vascularization in real-time, thereby reducing severe complication risks. This review highlights contrast-enhanced ultrasound as a transformative diagnostic tool for cesarean scar pregnancy management, despite existing evidence limitations.
