Aim: To evaluate the efficacy of an articulating laparoscopic needle holder in laparoscopic surgery for cesarean scar defect. Methods: We performed a retrospective case–control study at the Shiga University of Medical Science. Patients who underwent laparoscopic uterine scar repair were divided into an articulating laparoscopic needle holder (ArtiSential®) group and a rigid needle holder (conventional) group to compare the suture and total operative times. Uterine myometrial suturing involves a double‐layer interrupted suture, including a modified Gambee suture for the first layer. We measured the residual myometrial thickness using magnetic resonance imaging preoperatively and at 3 months postoperatively. Results: Both groups comprised 10 patients each. The time per stitch for the first and second layers was significantly shorter in the ArtiSential group than in the conventional group (median 208 s vs. 403 s, p < 0.0001 and median 17 s vs. 29 s; p < 0.0001, respectively). The total operating time was significantly shorter in the ArtiSential group (mean 188 min vs. 240 min, p = 0.0015). The postoperative residual myometrial thickness (mean 9.1 mm in the ArtiSential group and 9.6 mm in the conventional group) was significantly higher than the preoperative residual myometrial thickness (mean 1.6 mm in the ArtiSential group and 1.6 mm in the conventional group) (p < 0.0001 in both groups). Conclusions: An articulating needle holder is useful in laparoscopic surgery for cesarean scar defect, especially when a modified Gambee suture is required. [ABSTRACT FROM AUTHOR]

Background: Postpartum hemorrhage (PPH) and post-abortion hemorrhage (PAH) are life-threatening conditions. Purpose: To evaluate the efficacy and safety of uterine arterial embolization (UAE) for PPH and PAH and to investigate future fertility after UAE. Material and Methods: This study included 57 consecutive patients (mean age = 34 years) who underwent UAE for PPH (n = 46) and PAH (n = 11) at our institution between January 2011 and December 2022. Technical success, non-visualization of the peripheral portion of bilateral uterine arteries on angiography, and clinical success, complete hemostasis after UAE, were assessed. UAE-associated complications and factors related to clinical success were analyzed. Pregnancy outcomes after UAE and complications during subsequent pregnancy were investigated in 16 patients who desired fertility and were followed up for >1 year. Results: The technical and clinical success rates were 100% and 84.2%, respectively. Sepsis (n = 1) and uterine empyema (n = 1) were observed as severe complications. Placental disorder, bleeding within 24 h after delivery or abortion, ≥1.5 shock index, ≥6 units of transfusion erythrocytes, and ≥8 obstetrical disseminated intravascular coagulation score were significantly associated with unfavorable clinical outcomes. In total, 16 pregnancies were observed in 12 patients after UAE, three of which were miscarriages and 13 were successful live births. During pregnancy, uterine rupture (n = 1) and accreta (n = 1) were observed. Conclusion: UAE is an effective treatment for PPH and PAH. Although UAE could preserve future fertility, careful attention should be paid to perinatal management for unusual complications. [ABSTRACT FROM AUTHOR]

Background: Pregnancy and lactation-associated osteoporosis (PLO), as well as premenopausal osteoporosis, might be a predictor of future fracture. This study aimed to describe the clinical features of PLO as a subtype of premenopausal osteoporosis and to evaluate medical interventions for it. Methods: From an administrative claims database including 4,224,246 people in Japan, we classified women for whom the date of childbirth had been defined and who had suffered low-trauma fracture between the ages of 18–47 years as the premenopausal osteoporosis group. A fracture site for which the odds ratio for fractures occurring between 5 months before and 12 months after childbirth (around childbirth) was greater than 1 was considered the PLO site. We classified patients with a fracture at the PLO site around childbirth as the PLO group. The control group consisted of 500 women without fragility fractures. We investigated some drugs and diseases to explore fracture-causing factors, as well as medical interventions such as osteoporosis diagnosis, bone densitometry, anti-osteoporosis pharmacotherapy, and lactation inhibitors. Results: In total, 231 parous women were classified into the premenopausal osteoporosis group. The most common fracture was vertebral fracture and was likely to occur around childbirth, followed by distal radius and sacral fractures, which were rare around childbirth. Considering vertebral, pelvic, and proximal femoral fractures as PLO sites, 56 women with 57 PLO fractures were classified into the PLO group. The incidence of PLO was estimated at 460 per million deliveries. Ovulation disorder and high maternal age were associated with the development of PLO. Vertebral fracture was the most common PLO fracture. It was mainly diagnosed a few months, and possibly up to 1 year, postpartum. PLO patients with vertebral fractures underwent more medical interventions than did those with other fractures, but they were still inadequate. Conclusions: PLO with vertebral fracture was one of the major types of premenopausal osteoporosis. The prevalence of PLO is considered to be higher than previously thought, indicating the presence of potentially overlooked patients. More timely interventions for PLO might lead to the improved management of latent patients with premenopausal osteoporosis and reduce future fracture risk. [ABSTRACT FROM AUTHOR]

Chemotherapy and radiation therapy can cause gonadal dysfunction in women of reproductive age. Ovarian tissue cryopreservation is performed to restore fertility by allowing transplantation of the patient's frozen-thawed ovarian tissue or through future in vitro maturation and in vitro fertilization of frozen-thawed oocytes. Herein, we describe our initial experience with vaginal natural orifice transluminal endoscopic surgery for ovarian tissue preservation in a young woman with malignant tumor. A 23-year-old woman with anaplastic lymphoma kinase-positive malignant lymphoma was scheduled for hematopoietic stem cell transplantation after experiencing relapse following R-cyclophosphamide, doxorubicin, vincristine, and prednisolone therapy. Ovarian tissue cryopreservation was selected as only MII2 oocytes were collected. Vaginal natural orifice transluminal endoscopic surgery was performed to excise the left ovary. Ovarian tissues were frozen using the vitrification method. The operative time was 37 min, and blood loss was minimal. Pathological examination revealed no metastatic findings of malignant lymphoma and no thermal damage to the ovarian tissue due to bipolar disorder. The patient was discharged on the first day postoperatively, and her postoperative course was uneventful. The vaginal natural orifice transluminal endoscopic surgery technique can provide a safe and effective alternative to laparoscopy or laparotomy for the cryopreservation of ovarian tissue in young patients with cancer. We believe this method has potential application in sexually mature female cancer survivors. Plain language summary: Ovarian tissue cryopreservation with vaginal natural orifice transluminal endoscopic surgery Chemotherapy and radiotherapy can affect a woman's ability to have children by reducing ovarian function. This can make it hard to conceive even with fertility treatments. Freezing healthy ovaries before these treatments can help restore fertility. This can be done by freezing and later transplanting ovarian tissue or by fertilizing frozen eggs in a lab. Traditional surgery to remove ovaries can cause cosmetic issues and pain. But now, a new method called vaginal spontaneous opening transperitoneal endoscopic surgery is becoming more common. This surgery is less invasive, quicker, and causes less bleeding. We recently used this method to preserve ovarian tissue in young women with cancer. The surgery was successful with minimal complications. This new approach could offer a safer option for preserving fertility in female cancer survivors. [ABSTRACT FROM AUTHOR]

Factor XIII deficiency is an extremely rare autosomal recessive genetic disorder, occurring in 1 of 3–5 million people, and is associated with perinatal complications, such as habitual abortion and prolonged bleeding. Although plasma‐derived factor XIII (Fibrogamin®) carries a risk of infection and contains very low concentrated forms of factor XIII (FXIII) used for a pregnant woman with congenital coagulation factor XIII deficiency, recombinant factor XIII (rFXIII, Novo Thirteen®; Tretten®, Novo Nordisk, Bagsværd, Denmark), which has no risk of infection and is highly concentrated, has emerged as a novel formulation. Herein, we report the first case of a Japanese pregnant woman with congenital coagulation factor XIII deficiency successfully managed by rFXIII. She had a good perinatal course without pregnancy‐related complications and transfusion through the perinatal period. [ABSTRACT FROM AUTHOR]

Introduction: Epithelioid endothelial tumor (ETT) is an extremely rare tumor that typically occurs in women of reproductive age. The diagnosis tends to be delayed because it often necessitates a total hysterectomy. Therefore, it is important to understand ETT macroscopic and imaging findings. Here, we report a case of ETT with detailed macroscopic and imaging findings. Case Presentation: A 39-year-old woman with positive pregnancy test results was admitted to a nearby hospital. No gestational sac was found in the uterus, and magnetic resonance imaging (MRI) revealed a cystic mass of approximately 7 cm that extended continuously from the anterior wall of the lower uterine segment into the pelvic cavity. She underwent laparoscopic and hysteroscopic surgeries for a ruptured cervical pregnancy. Pathology of the specimens obtained from this surgery did not allow for the diagnosis of ETT. Two months after the surgery, as the serum human chorionic gonadotropin β subunit (β-HCG) level did not decrease, she was diagnosed with low-grade gestational trophoblastic neoplasia, leading to the administration of chemotherapy. After three regimens of chemotherapy over 9 months, her β-HCG level decreased but did not reach normal levels. Ultimately, a total hysterectomy was performed. The pathological diagnosis was mixed ETT and choriocarcinoma. A literature review revealed several cases similar to ours. Conclusion: ETT in the lower uterus often perforates the myometrium and forms cystic lesions in the retroperitoneal space or subserosa. The MRI and laparoscopic/hysteroscopic findings in this case may have contributed to the early diagnosis of ETT. [ABSTRACT FROM AUTHOR]

Thoracoamniotic shunting (TAS) is an effective treatment for fetal pleural effusion. We report a case of bilateral fetal pleural effusion in which catheter displacement into the amniotic cavity occurred due to fetal movement after TAS. Initially, left TAS was performed twice using a 60-mm catheter, resulting in displacement and the catheter being pinched between the fetal fingers. Subsequently, a 50-mm catheter was employed for left TAS, which successfully prevented further displacement. Labor was induced at 35 weeks and three days of gestation due to an increase in right fetal pleural effusion. Following delivery, the infant was managed with directional positive airway pressure and drainage of the pleural effusion and remained stable on respiratory support. This case highlights the importance of tailoring catheter length and placement based on the thickness of the fetal chest wall to minimize displacement risks associated with fetal movement., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: There is no consensus on whether platinum doublet chemotherapy or lenvatinib and pembrolizumab (LEN/PEM) is superior for advanced or recurrent endometrial cancer. Thus, this study aimed to compare the prognosis and adverse events in patients with advanced or recurrent endometrial cancer treated with platinum doublet chemotherapy or LEN/PEM., Methods: We retrospectively reviewed the medical records of patients who received platinum doublet chemotherapy or LEN/PEM at our institution for advanced or recurrent endometrial cancer and had a history of platinum-based chemotherapy between January 2013 and August 2023., Results: During the study period, 11 regimens were identified in the platinum doublet chemotherapy group, and 11 regimens were identified in the LEN/PEM group. The objective response rates of the platinum doublet chemotherapy and LEN/PEM groups were 36.4% and 54.5% (P=0.67), respectively. The 6-month progression-free survival (PFS) rates of the platinum doublet chemotherapy and LEN/PEM groups were 27.3% (95% confidence interval [CI], 13.8-40.7%) and 70.0% (95% CI, 55.5-84.5%), respectively. The differences were significant between the two groups. Multivariate analyses of histology, prior lines of chemotherapy, platinum-free intervals, and regimens revealed that the LEN/PEM group had significantly better PFS rates., Conclusion: Treatment with LEN/PEM resulted in significantly longer PFS than that of treatment with platinum doublet chemotherapy in patients with advanced and recurrent endometrial cancer. However, further large-scale studies are required to validate these findings.

Umbilical cord rupture, though rare, is a severe obstetric complication with significant implications for neonatal morbidity and mortality. We present the case of a 38-year-old primiparous female diagnosed with a single umbilical artery (SUA) and velamentous cord insertion (VCI) in late pregnancy. At 40 weeks of gestation, during labor induction, the patient suddenly experienced massive vaginal bleeding and fetal bradycardia, necessitating an emergency cesarean section. Postoperatively, it was confirmed that the umbilical cord had ruptured. The neonate required immediate and intensive resuscitation, including blood transfusion and therapeutic hypothermia. Remarkably, despite the critical initial condition, the neonate exhibited no neurological deficits and was discharged in stable condition on the 27th day. The presence of SUA and VCI likely increased the vulnerability of the umbilical cord, predisposing it to rupture. This case emphasizes the importance of prenatal ultrasound in detecting umbilical cord abnormalities such as SUA and VCI. The early detection of these abnormalities allows for proactive management, including closer monitoring and timely surgical intervention, which are crucial for optimizing neonatal outcomes. This report provides valuable insights into the pathophysiology and management of umbilical cord rupture., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Pemphigoid gestationis (PG) is a rare autoimmune blistering disorder that typically manifests during the second or third trimester of pregnancy. It is characterized by intensely pruritic urticarial plaques and blister formation, driven by an autoimmune response against the BP180 protein in the basement membrane. In this report, three cases of PG are presented, each illustrating distinct clinical courses and management strategies. The first case involves a 32-year-old primigravida at 31 weeks of gestation who presented with abdominal blisters that were unresponsive to topical steroids. Oral prednisone at a dosage of 15 mg was initiated at 33 weeks, leading to the resolution of the rash by 37 weeks. She subsequently delivered vaginally at 40 weeks. The second case concerns a 37-year-old multigravida who developed blisters on her limbs and abdomen at 27 weeks, which improved with the application of topical steroids. Due to a history of a previous cesarean section, she delivered via elective cesarean section at 38 weeks. The third case involves a 35-year-old multigravida who experienced fetal growth restriction starting from 29 weeks. She developed a mild erythematous, pruritic rash, and blisters at 33 weeks and required an emergency cesarean section at 33 weeks due to non-reassuring fetal status. The diagnosis of PG was confirmed postpartum. These cases underscore the clinical variability and potential complications associated with PG. They also suggest that the severity of PG's cutaneous manifestations may not directly correlate with pregnancy outcomes. Early detection and individualized management are crucial to optimizing both maternal and neonatal outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Adnexal cyst torsion in late preterm pregnancies is rare, but it frequently causes secondary uterine contractions. Thus, deciding on performing a simultaneous cesarean section due to the potential for early postoperative labor onset is crucial despite no obstetric indications. Here, we report a case of adnexal torsion at 34 weeks of gestation treated with emergency surgery, followed by a full-term vaginal delivery, along with a literature review. A 31-year-old primigravida at 34 weeks and four days of gestation presented to the emergency department with right lower abdominal pain. An emergency laparotomy was performed to achieve term delivery, suspecting right ovarian cyst torsion without signs of fetal distress. General anesthesia with sevoflurane was selected over spinal anesthesia, considering the incision height. The patient was placed in the left lateral decubitus position on the operating table to ensure proper visualization and maintain uterine circulation. A 4-cm transverse skin incision was made under ultrasound guidance, revealing the twisted right paratubal cyst immediately beneath. The cyst was excised, and the torsion was relieved. The postoperative course was uneventful, and spontaneous labor occurred at 39 weeks and six days of gestation, resulting in a vaginal delivery at 40 weeks. This case demonstrates that even late preterm adnexal torsion can be managed safely with appropriate surgical techniques, allowing for a subsequent term vaginal delivery., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: To identify a relatively high-risk population in postoperative intermediate-risk cervical cancer and evaluate the effect of platinum-based adjuvant chemotherapy (CT)., Methods: We retrospectively reviewed the medical records of patients with stage IA2-IIA cervical cancer who had been treated with radical hysterectomy and pelvic lymphadenectomy and classified as the intermediate-risk group for recurrence by postoperative pathological examination from January 2007 to December 2018 at 3 medical centers in Japan. First, patients with intermediate-risk were stratified by histological type and the number of intermediate-risk factors (IRF; large tumor diameter, lymph vascular space invasion, and deep cervical stromal invasion) and then divided into 2 groups: high and low-risk population (estimated 5-year recurrence-free survival [RFS] rate with no further therapy [NFT] <90% and ≥90%, respectively). Second, the efficacy of CT for the high-risk population was evaluated by comparing RFS and overall survival (OS) between the patients receiving CT and those with NFT., Results: In total, 133 patients were included in the analysis. Among patients with squamous cell carcinoma (SCC) with all IRF or those with non-SCC with 2 to 3 IRF, the 5-year estimated RFS was <90% when treated with NFT. In this population, adjuvant CT was significantly superior to NFT regarding RFS (log-rank, p=0.014), although there was no statistical difference in OS., Conclusion: Patients with SCC with all 3 IRFs and those with non-SCC with 2 to 3 IRFs were at high risk for recurrence. Adjuvant CT is a valid treatment option for these populations., Competing Interests: No potential conflict of interest relevant to this article was reported., (© 2025.

Objective: To investigate the association between cesarean section (CS) and postpartum fertility and dysmenorrhea using data from a Japanese insurance registry., Methods: This retrospective cohort study used a data set of patients registered between 2007 and 2021 in an insurance registry comprising specific employee-based health insurance companies in Japan. Of those data sets, we included data from participants who had their first recorded childbirth between 2014 and 2018. The exclusion criteria were any prior deliveries, dysmenorrhea, or complications that would affect the next pregnancy or postpartum dysmenorrhea since 2007. The occurrence of subsequent childbirth and postpartum dysmenorrhea until 2021 was compared between the CS and vaginal delivery (VD) groups using the log-rank test and Cox proportional hazards model with stratification according to age and age matching., Results: This study included 25,984 (5,926 after age matching) and 5,926 participants in the VD and CS groups, respectively. After age matching, the rate of subsequent childbirth was 18.3% and 16.3%, and the rate of postpartum dysmenorrhea was 6.5% and 7.8% in the VD and CS groups, respectively. There were fewer subsequent childbirths in the CS group than in the VD group after age matching in the stratified Cox proportional hazards model (hazard ratio [HR] 95% confidence interval [CI]: 0.86 [0.79-0.94]). The CS group had a significantly higher risk of dysmenorrhea (HR [95% CI]: 1.18 [1.03-1.36])., Conclusions: Although confounding might be existing, our study suggests that CS might be associated with decreased postpartum fertility and increased dysmenorrhea. The medical indications for CS should be carefully determined; post-CS women should be meticulously followed up., Competing Interests: The authors declare no conflict of interest., (© Mizuki Ohashi et al., 2023; Published by Mary Ann Liebert, Inc.)
