Objectives: Laparoscopic myomectomy (LM) is a procedure with a high rate of postoperative adhesions, which can lead to complications such as bowel obstruction and subsequent surgical problems, making anti-adhesion measures important. Various anti-adhesion materials are already on the market and have shown efficacy, but dextrin hydrogel spray (AdSpray™), an anti-adhesion material launched in 2017, has not yet been reported in the field of gynecology, although there are papers showing its usefulness in the surgical field such as repeat hepatectomy and ileostomy closure. Thereby, we investigated the postoperative status of AdSpray™ in LM. Materials and Methods: We report 24 cases in which AdSpray™ was used at Teine Keijinkai Hospital from 2018 to 2021 for LM, followed by cesarean section (CS) from 2019 to 2022. Adverse effects related to AdSpray™ and the presence of uterine adhesions in CS were examined. Results: Adhesions were observed in 4 (16.7%) cases, none of which resulted in significant adverse effects of AdSpray™. Conclusion: AdSpray™ was effective in preventing adhesion and may be an option as an anti-adhesion material in LM. [ABSTRACT FROM AUTHOR]

This prospective cohort study aimed to evaluate the performance of Flora select™ (FS), a newly developed real-time PCR test, for the assessment of the vaginal microbiome during early pregnancy. Five hundred and fifty-six pregnant women underwent examinations of FS, Nugent score—a Gram-staining scoring system for the diagnosis of bacterial vaginosis (BV)—and conventional bacterial culture between 8 weeks and 12 gestational weeks. Nugent scores of 0–3, 4–6, and ≥7 were found in 469 (84.2%), 41 (7.4%), and 47 (8.5%) of the women, respectively. Relative dominance rates of Lactobacillus species of high (≥80% medium (50%≤, <80%), and low (0.1≤, <50%), and no detection (<0.1%) were 63.0%, 8.8%, 17.1%, and 11.2%, respectively. Gardnerella, Prevotella, Atopobium, Streptococcus, Ureaplasma, and Mycoplasma species were detected in 23.9%, 17.6%, 17.1%, 7.0%, 23.0%, and 4.9% of the women, respectively. Gardnerella species were detected in all women with Nugent scores ≥7 and Ureaplasma were detected in 40.4% of them. BV-associated bacterial species were also detected in 70.7% of women with Nugent scores of 4–6. Gardnerella, Prevotella, Atopobium, Streptococcus, Ureaplasma, and Mycoplasma species were highly prevalent in women with Nugent scores ≥4 or Lactobacillus species <50%. FS detected Gardnerella, Prevotella, and Atopobium species more effectively than conventional bacterial culture. FS could determine relative dominance rates of Lactobacillus species in the vaginal microbiome, and simultaneously detect four kinds of BV-associated bacteria, Ureaplasma and Mycoplasma species. Therefore, FS may be clinically useful for the screening of the vaginal microbiome during pregnancy to prevent preterm birth and for the assessment of the vaginal microbiome after BV treatments.

Objectives: This prospective study evaluated whether endometriosis is associated with chronic endometritis (CE) and affects the uterine endometrium microbiome (UEM) in women with repeated implantation failure (RIF). Methods: Forty-three women with RIF were divided into 12 with endometriosis (EM) and 31 without endometriosis (non-EM). The UEM was examined by 16S ribosomal RNA (rRNA) sequencing, and CE was determined by CD 138 staining (plasma cells > 5.15/10 mm2) simultaneously. Results: The EM group had a higher bacterial number (EM vs. non-EM; median [range], 6.5 vs. 3 [3–11, 1–16], p = 0.009), while the frequency of Lactobacillus species did not change. The rates of presence of Dialister (41.7% [5/12] vs. 3.3% [1/31], p = 0.004) and Streptococcus species (58.3% [7/12] vs. 16.1% [5/31], p = 0.017) were higher in the EM group. The prevalence of CE did not differ between the two groups. Multivariable logistic regression analysis revealed that the presence of Dialister species (odds ratio, 10.97, 95% confidence interval, 1.17–249.37, p = 0.036) was associated with endometriosis. In the EM group, five women with Dialister species had a higher number of bacterial species (10 vs. 5 [6–11, 3–7], p = 0.021) and higher Shannon diversity index (0.50 vs. 0.20 [0.19–1.39, 0.03–0.46], p = 0.026) than seven without Dialister species. Conclusions: Dialister and Streptococcus species, and the increased number of bacterial species in UEM may be related to the pathogenesis of RIF complicated by endometriosis. [ABSTRACT FROM AUTHOR]

Objectives: The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes. Materials and Methods: The retrospective cohort study included 43 pregnant cases with adenomyosis who did not undergo laparoscopic surgery before pregnancy (nonsurgery group; 26 cases) and did (surgery group; 17 cases). To evaluate the impact of surgery on perinatal outcomes, nine obstetric complications including preterm delivery, hypertensive disorder of pregnancy, placental malposition, oligohydramnios, gestational diabetes mellitus, uterine rupture, abruptio placentae, and postpartum hemorrhage were selected. One obstetric complication was counted as one point (Maximum 9 points for one person). The obstetrical morbidity was compared by adding up the number of relevant events (0--9) between the two groups. Apgar score, umbilical artery pH (UApH), neonatal intensive care unit (NICU) admission, and neonatal death were also examined. Results: The surgery group had a significantly lower prevalence of fetal growth restriction compared to the nonsurgery group (nonsurgery vs. surgery; 26.9%, 7/26 vs. 0%, 0/17: P = 0.031). No differences were found in the morbidity of the nine obstetric complications (19.2%, 45/234 vs. 13.7%, 21/153), gestational weeks (mean ± standard deviation, 37.2 ± 2.4 vs. 36.4 ± 3.2), birth weight (2573.6 ± 557.9 vs. 2555.4 ± 680.8 g), Apgar score (1, 5 min; 8.0 ± 0.7 vs. 7.7 ± 1.2, 8.9 ± 0.6 vs. 8.5 ± 1.8), UApH (7.28 ± 0.08 vs. 7.28 ± 0.06), NICU admission (26.9%, 7/26 vs. 41.2%, 7/17), and neonatal death (0%, 0%) between both groups. Conclusion: Laparoscopic adenomyomectomy may not increase obstetric complications, although attention must be paid to uterine rupture during pregnancy. [ABSTRACT FROM AUTHOR]

Retained products of conception (RPOC) is a condition in which trophoblastic tissue remains in the uterus after pregnancy, causing massive hemorrhage in some cases. Though RPOC is commonly treated by intrauterine curettage or hysteroscopic resection uterine artery embolization or hysterectomy may be performed in case of massive bleeding. We experienced two cases of RPOC after surgery for missed abortion that failed to respond to conservative treatment and required surgical treatment. They were treated by hysteroscopic resection with temporary balloon catheter occlusion of bilateral internal iliac arteries for fertility preservation. After the balloon catheters were inflated, the reduction of blood flow to RPOC was observed under transvaginal ultrasound. In both cases, good visualization was maintained throughout the surgery with minimal bleeding. They were discharged the next day and resumed menstruation 1 month after surgery. This paper demonstrates the usefulness of this procedure as a minimally invasive and fertility‐preserving surgery. [ABSTRACT FROM AUTHOR]
