Abstract
Objectives This study aimed to evaluate the effectiveness of prophylactic laparoscopic surgery for avoiding adnexal torsion in pregnant women with benign adnexal masses. Materials and Methods This report contains two analyses, each for a different group of patients. Analysis 1: Surgical and pregnancy outcomes were examined among the 126 cases who underwent laparoscopic assisted cystectomy for adnexal masses during pregnancy in our hospital between January 2001 and December 2020. Analysis 2: The incidence of adnexal torsion during pregnancy was evaluated among the cases with adnexal masses ≥5 cm who opted for conservative follow-up in our hospital between January 2011 and December 2020. Results In analysis 1, the most common pathological diagnosis was a mature cystic teratoma (76.2%). The mean gestational age at surgery was 13.1 ± 1.3 weeks. No cases were converted to laparotomy and oophorectomy. Regarding delivery outcomes, 97.4% of cases went on to have full-term deliveries. In Analysis 2, the incidence of adnexal mass ≥5 cm that did not resolve spontaneously during pregnancy was 89 cases (0.8%). The frequency of malignancy was 3 cases (0.03%). In 28 cases who opted for conservative treatment, 5 (17.9%) underwent emergency surgery for adnexal torsion. Conclusion Prophylactic surgery for benign adnexal masses during pregnancy can be performed laparoscopically and preserved ovarian functions. In pregnant women with adnexal masses that do not resolve spontaneously, planning laparoscopic surgery is considered beneficial for complications, such as adnexal torsion.

Abstract
Functionally rejuvenated human papilloma virus-specific cytotoxic T lymphocytes (HPV-rejTs) generated from induced pluripotent stem cells robustly suppress cervical cancer. However, autologous rejT generation is time consuming, leading to difficulty in treating patients with advanced cancer. Although use of allogeneic HPV-rejTs can obviate this, the major obstacle is rejection by the patient immune system. To overcome this, we develop HLA-A24&-E dual integrated HPV-rejTs after erasing HLA class I antigens. These rejTs effectively suppress recipient immune rejection while maintaining more robust cytotoxicity than original cytotoxic T lymphocytes. Single-cell RNA sequencing performed to gain deeper insights reveal that HPV-rejTs are highly enriched with tissue resident memory T cells, which enhance cytotoxicity against cervical cancer through TGFβR signaling, with increased CD103 expression. Genes associated with the immunological synapse also are upregulated, suggesting that these features promote stronger activation of T cell receptor (TCR) and increased TCR-mediated target cell death. We believe that our work will contribute to feasible "off-the-shelf" T cell therapy with robust anti-cervical cancer effects.

Abstract
AIMS To determine the association between drinking habits and social factors among women undergoing assisted reproductive technology (ART) treatment in Japan. METHODS The study participants who provided answers for the questionnaire concerning alcohol consumption were 1017 female patients undergoing ART treatment were enrolled in the Japan-Female Employment and Mental Health in assisted reproductive technology (J-FEMA) study between August and December 2018. Patient characteristics, including demographic, clinical, and socioeconomic status, were assessed using a self-administered questionnaire which was distributed only once during the period, regardless of their first or follow-up examination. We defined current drinkers who drank ≥46 g of ethanol per week as the habitual drinking group. The risk factors for habitual drinking were analyzed using multivariable-adjusted logistic regression. RESULTS The proportion of habitual drinkers was 15.5% in this study population. The multivariable-adjusted odds ratios (95% confidence interval) for habitual drinking were 2.27 (0.99-5.21) for women aged ≥35 years versus those <35 years, 4.26 (1.98-9.16) for women having partners who currently drink compared to those with partners without current drinking, 1.84 (1.08-3.12) for women without a history of childbirth versus those with, and 1.77 (1.00-3.14) for working women compared with those not working. CONCLUSIONS In our study, habitual drinking among women undergoing ART treatment was significantly associated with older age, no history of childbirth, partner's current drinking status, and working.

Abstract
Introduction Chronic endometritis (CE) is a persistent inflammatory condition of the endometrium characterized by the infiltration of plasma cells in the endometrial stroma. CD138 immunohistochemistry is considered to improve the CE diagnosis rate. Methods Using the number of CD138-positive cells equal or greater than five as a diagnostic criterion for CE, we identified 24 CE and 33 non-CE cases among women with infertility. We conducted RNA-sequencing analysis for these 57 cases in total as an attempt to elucidate the molecular pathogenesis of CE and to search for new biomarkers for CE. Results and Discussion By comparing CE and non-CE groups, we identified 20 genes upregulated in the endometria of CE patients, including 12 immunoglobulin-related genes and eight non-immunoglobulin genes as differentially expressed genes. The eight genes were MUC5AC, LTF, CAPN9, MESP1, ACSM1, TVP23A, ALOX15, and MZB1. By analyzing samples in the proliferative and secretory phases of the menstrual cycle separately, we also identified four additional non-immunoglobulin genes upregulated in CE endometria: CCDC13 by comparing the samples in the proliferative phase, and OVGP1, MTUS2, and CLIC6 by comparing the samples in the secretory phase. Although the genes upregulated in CE may serve as novel diagnostic markers of CE, many of them were upregulated only in a limited number of CE cases showing an extremely high number of CD138-positive cells near or over one hundred. Exceptionally, TVP23A was upregulated in the majority of CE cases regardless of the number of CD138-positive cells. The upregulation of TVP23A in the endometria of CE cases may reflect the pathophysiology of a cell-type or cell-types intrinsic to the endometrium rather than the accumulation of plasma cells. Our data, consisting of clinical and transcriptomic information for CE and non-CE cases, helped us identify gene expression signatures associated with CE.

Abstract
AIM Even though 95% of struma ovarii are benign, it is often overtreated because of the difficulty to distinguish it from malignancy. In this study, our aim was to evaluate the current state of the preoperative diagnosis and the selection of the surgical procedure, and to improve preoperative diagnostic accuracy by retrospectively reviewing imaging findings. METHODS We retrospectively reviewed the clinical course and imaging characteristics of 18 patients who were diagnosed postoperatively with struma ovarii, pathologically, at our institution between 2015 and 2021. RESULTS The preoperative diagnoses included benign ovarian tumor in eight cases, borderline in four cases, and malignant in six cases. None of the cases were diagnosed as struma ovarii preoperatively. Of the seven patients who had confirmed a desire for future childbearing, four patients were suspected for borderline or malignant tumor preoperatively, and underwent abdominal adnexectomy. In patients without a desire for childbearing, laparoscopic surgery was performed in only 45% of the patients whose preoperative diagnosis was benign. On magnetic resonance imaging (MRI), 54% of the cases showed enhanced solid components, which is characteristic of malignant tumors, but diffusion restriction was observed in only 11%. On computed tomography (CT), 78% of the cases showed a high attenuation lesion reflecting thyroid tissue. CONCLUSIONS Struma ovarii is difficult to distinguish from malignancy preoperatively, making the choice of surgical approach complicated. A comprehensive evaluation of diffusion-weighted MRI and CT findings may improve the accuracy of preoperative diagnosis of struma ovarii.

Abstract
Purpose Sleep is an essential factor for athletes, and it is important to intervene in sleep to manage it. We need a device that can evaluate sleep easily and constantly. Consumer wearable devices can be useful tools for athletes. In order to use consumer wearable devices in clinical research, it is essential to conduct a validation study. Thus, we conducted a validation study to assess the Fitbit Alta HRTM (FBA)- a consumer wearable device with an accelerometer and a heart rate monitor to detect sleep stages and quality against electroencephalographic (EEG) studies in athletes. Patients and Methods Forty college athletes participated in the study. EEG was applied to participants simultaneously while wearing FBA. Results Regarding sleep parameters, there was a strong correlation between the total sleep time (TST)-EEG and the TST-Fitbit (r = 0.83; p < 0.001). Regarding the sleep stages, there was a modest correlation between the N3 sleep-EEG and the N3 sleep-Fitbit (r = 0.68; p < 0.001). In addition, there was a strong correlation between the percentage of N3 sleep in between sleep onset and initial rapid eye movement sleep-EEG and those on Fitbit (r = 0.73; p < 0.001). Conclusion These results demonstrate that FBA facilitates sleep monitoring and exhibits acceptable agreement with EEG. Therefore, FBA is a useful tool in athletes' sleep management.

Abstract
Pyomyoma is an extremely rare complication, defined as an infection of a uterine leiomyoma. We describe two cases of pyomyoma that were initially considered to be tubo-ovarian abscesses but were later diagnosed as pyomyomas and managed with laparoscopic surgery. Case 1 was a 26-year-old nulliparous woman who was previously diagnosed with bilateral endometriomas and presented to the hospital with lower abdominal pain. Magnetic resonance imaging revealed bilateral endometrial cysts and a 4-cm mass consistent with a tubo-ovarian abscess. The patient experienced continuous pain, and the cyst in the left adnexa enlarged; thus, laparoscopic surgery was performed. The cystic tumor in her uterus contained purulent fluid. Therefore, an abscess in the degenerative subserous myoma was diagnosed. Case 2 was a 47-year-old nulliparous woman who had undergone total mastectomy and postoperative radiotherapy for breast cancer. She was undergoing hormone therapy when she presented to the hospital with lower abdominal pain, fever, and increased inflammatory markers. Computed tomography revealed a 7-cm tumor with rim enhancement in her left adnexa; therefore, a tubo-ovarian abscess was suspected. After admission, drainage was performed under transvaginal ultrasound guidance, and antibiotics were administered. However, these treatments did not relieve her abdominal pain. Emergency laparoscopic surgery was performed, and intraoperative findings demonstrated an abscess in the degenerative subserous myoma of the uterus with normal adnexa. Laparoscopic hysterectomy and bilateral salpingectomy were performed. Laparoscopic surgery was effective for both patients. Delayed diagnosis of pyomyoma can result in serious complications. Timely surgery with concomitant antibiotic treatment may facilitate good outcomes. Pyomyoma is extremely rare and can be difficult to diagnose. Symptoms of pyomyoma are similar to those of other reproductive conditions. Pymyoma may occur in young women. Surgery, in addition to antibiotic treatment, should be considered for pyomyoma.

Abstract
INTRODUCTION We aimed to identify the characteristics of cases involving postoperative bleeding after laparoscopic gynecologic surgery, and to clarify the optimal cutoff value of postoperative drainage and vital sign trends for predicting the need for re-laparoscopy. METHODS Of 6366 patients with gynecologic benign pathologies who underwent laparoscopic surgery at our institution between 2009 and 2018, 13 (0.2%) required re-laparoscopy for postoperative bleeding. After reviewing the perioperative course in the re-laparoscopy group, we examined the postoperative total drainage volume (mL), drainage flow rate (mL/h), and vital sign trends in the re-laparoscopy group (n = 13) and among patients with substantial drainage volume ≥300 mL at 12 hours postoperatively but who did not need re-laparoscopy (observation group, n = 107). RESULTS In the re-laparoscopy group, initial laparoscopic surgery included uterine surgery (myomectomy, n = 7; hysterectomy, n = 1), adnexal surgery (n = 3), and uterine plus adnexal surgery (n = 2). Postoperative bleeding sites included the uterine wound (n = 6), adnexal wound (n = 5), umbilical trocar site (n = 1), and mesentery (n = 1). The re-laparoscopy and observation groups did not differ regarding initial surgical characteristics or postoperative vital sign trends. For distinguishing between the re-laparoscopy and observation groups, the drainage flow rate was superior to total drainage volume. Continuous excessive drainage (flow rate >50 mL/h) at 3 hours postoperatively was associated with a remarkably increased risk for re-laparoscopy (odds ratio, 40.07; 95% confidence interval, 5.44 to 1776.41, P < 0.001). CONCLUSION In cases with continuous excessive drainage later than 3 hours postoperatively (flow rate >50 mL/h) should be considered for exploratory re-laparoscopy to enable prompt diagnosis and intervention.

Abstract
Sleep is essential for athletes to recover physical fitness. It has been suggested that sleep is affected by muscle volume. Compared to female athletes, male athletes with greater muscle volume may have inferior objective sleep quality. This study aimed to assess the relationship between body composition and objective sleep parameters in male and female athletes. The body composition of 17 male and 19 female collegiate athletes were measured, and they underwent overnight home sleep monitoring. Compared with female athletes, male athletes had more muscle mass and less fat mass. Moreover, male athletes had lower sleep efficiency, longer sleep onset latency, higher arousal index, less rapid eye movement (REM) sleep, and lower percentage of slow-wave (N3) sleep in the initial non-REM sleep. Furthermore, the percentage of muscle mass was inversely related, whereas fat mass or percentage of fat mass was directly related to the percentage of N3 sleep in the initial non-REM sleep. Overall, there were no significant association between sex and sleep parameters. However, a significant correlation was found within both subgroups. Objective sleep quality was suggested to be worse in male athletes than in female athletes, implying that sleep architecture may be related to the muscle volume.

Abstract
AIM We aimed to describe the clinical presentation, operative or medical management, and postoperative recurrence of bladder endometriosis (BE). METHODS We conducted a national survey to investigate BE cases from 2006 to 2016 in Japan. Histologically diagnosed cases were extracted and then investigated for the following factors: age at diagnosis, body mass index, symptoms, imaging modalities, surgical therapy, hormonal therapy, follow-up period, and postoperative recurrence. RESULTS Eighty-nine patients with pathologically benign BE were identified. Eighty patients underwent surgery, whereas nine did not. Moreover, 34 and 44 patients underwent transurethral resection (TUR) and partial cystectomy (PC), respectively. Cumulative recurrence rates were significantly higher with TUR than with PC (p < 0.05). The recurrence rate tended to be higher after laparoscopic PC (n = 24) than after open PC (n = 20), but the difference was not statistically significant (p = 0.0879). Of the nine nonsurgical patients, eight received hormonal therapy and one did not. Efficacy rates of dienogest, GnRH agonist, and OC were 85.7%, 66.7%, and 66.7%, respectively. Of five patients with BE extending to the ureter or ureteral orifices, two underwent PC and ureteroneocystostomy and one underwent total nephroureterectomy due to renal function loss. CONCLUSION To our knowledge, this is the first study to compare the postoperative recurrence of BE after TUR and PC. We found that cumulative recurrence rate is significantly lower after PC than after TUR. BE extending to the ureter or ureteral orifices is a very challenging condition. Further studies are required for the optimal management of BE.

Abstract
The aim of this publication is to disseminate the clinical practice guidelines for the treatment of intestinal, bladder/ureteral, thoracic and umbilical endometriosis, already published in Japanese, to non-Japanese speakers. For developing the original Japanese guidelines, the clinical practice guideline committee was formed by the research team for extragenital endometriosis, which is part of the research program of intractable disease of the Japanese Ministry of Health, Labor and Welfare. The clinical practice guideline committee formulated eight clinical questions for the treatment of extragenital endometriosis, which were intestinal, bladder/ureteral, thoracic and umbilical endometriosis. The committee performed a systematic review of the literature to provide responses to clinical questions and developed clinical guidelines for extragenital endometriosis, according to the process proposed by the Medical Information Network Distribution Service. The recommendation level was determined using modified Delphi methods. The clinical practice guidelines were officially approved by the Japan Society of Obstetrics and Gynecology and the Japan Society of Endometriosis. This English version was translated from the Japanese version.

Abstract
AIM The aim of the study was to assess the incidence of postoperative adhesion by baseball running suture using barbed suture (BS) in laparoscopic myomectomy in comparison with sutures using an absorbable thread. METHODS Two hundred fifteen patients who underwent second-look laparoscopy (SLL) 6 months after laparoscopic myomectomy at our hospital between 2010 and 2014 were retrospectively reviewed. The incidence, numbers, types, and extent of adhesions were evaluated according to the more comprehensive adhesion scoring method. Propensity score matching (PS) (1:1) between the groups was performed by using the diameter of the largest myoma, the number of enucleated myomas, and the type of adhesion barrier. RESULTS Running baseball sutures and running sutures were applied to 28 and 187 patients with unidirectional BS and absorbable thread, respectively, to close the incised serosal wounds enucleating largest myomas during laparoscopic myomectomy. After PS matching for the patients, surgical findings and the incidence of postoperative wound adhesions were compared between the groups, including 22 patients each. The surgical findings were similar between the groups, except for the total surgical duration and blood loss (medians), which were significantly shorter and lower in the BS group than in the absorbable thread group (70 vs. 100 min; p = 0.01, 50 vs. 100 mL; p = 0.02). Regarding findings of SLL, no significant differences in the incidence of postoperative wound adhesions were found between the groups (BS, 4/22 [18.2%] versus absorbable thread, 8/22 [36.4%]; p = 0.31). CONCLUSION Our data indicated that the incidence of postoperative adhesion following the use of BS for wound closure in laparoscopic myomectomy was similar to that following the use of conventional suture.

Abstract
AbstractPreviously we reported laparoscopic removal of compression sutures due to uterine ischemia and related pain, which has two of the difficult aspects: (1) maneuvering the curved needle to perform compression suturing in the narrow surgical field, and (2) distinguishing between the threads of the cesarean section wound sutures versus the vertical compression sutures during removal, as the threads are the same white color. We performed vertical compression sutures for intrapartum hemorrhage with total placental previa, and modified both the needle type and the color of the thread used for uterine compression sutures during cesarean section. After the operation, we performed successful laparoscopic removal of compression sutures for postoperative focal pain. Changing the needle type and color helped to perform operations. The present case supports the concept that the laparoscopic removal of uterine compression suturing is useful for controlling pain in cases where general analgesics are ineffective.

Abstract
Cervicovaginal atresia with a functional uterus is rare. There are no established surgical methods to treat this condition, and only a few reports have been published on surgical techniques. Furthermore, postoperative complications, such as restenosis, often require reoperation. A 19-year-old woman was pointed out cervical hypoplasia and referred to our hospital for further examination and treatment. A pelvic examination revealed that the vagina had a slight recession with a blind end. Transrectal ultrasound and pelvic magnetic resonance imaging revealed congenital vaginal agenesis and cervical hypoplasia. Elective surgery was performed after reshaping the vagina. A radical surgery was performed 10 months later after sufficient self-dilation by using Frank's technique in an outpatient setting. At first, we approached by laparoscopically to correct autologous peritoneum and to bladder detach, then the cervical canal was identified. Next, a skin biopsy punch was used several times to hollow out the cervical tissue to shape and expand the cervical canal. A catheter was then placed in the uterus and autologous peritoneum was wrapped around it and fixed to the cervical canal. The catheter was removed 6 weeks postoperatively, and the patient continued dilating her vagina until she was able to have sexual intercourse, and then stopped the self-dilation. Eight months postoperatively, the patient did not report any menstrual irregularities. It is important to make corrections to prevent restenosis of the vagina and cervical canal and prevent the symptoms from recurring. Make use of autologous peritoneum as graft onto the cervical canal is effective method for the treatment of cervicovaginal atresia.

Abstract
BACKGROUND Sleep is an important recovery period for athletes. In general, women are not satisfied with their sleep quality, which is also true for female soccer players, although the reasons remain to be elucidated. This study aimed to confirm sex difference in sleep quality among athletes from various fields of sport, and to investigate factors related to poor subjective sleep quality in male and female athletes. METHODS We collected data concerning subjective sleep quality, measured by Pittsburgh Sleep Quality Index (PSQI), from athletes who were 16 to 40 years of age and played various types of sports. Data concerning their sports, lifestyle, and sleep issues and sleep environments, and also menstrual issues for females, were collected. RESULTS Data from 207 male athletes and 215 female athletes were assessed. Among them, 31.4% of men and 48.8% of women had poor subjective sleep quality (i.e., PSQI≥6). In male athletes, witnessed apnea, episodes of disorientation or confusion during the time of sleep, long time gap between dinner and bedtime, and turning on the heating in the winter, were identified as factors associated with poor sleep quality by multivariate analysis, whereas in female athletes, bathing close to bedtime, habitual drinking, and being annoyed by noises at bedtime were identified. CONCLUSIONS In both populations, females had poorer subjective sleep quality than males. Sex differences exist in factors associated with poor subjective sleep quality. Thus, different approaches should be considered to improve their sleep quality.

Abstract
AIM Decidualization is essential for embryo implantation and placental development. We aimed to obtain transcriptome and epigenome profiles for primary endometrial stromal cells (ESCs) and in vitro decidualized cells. MATERIALS & METHODS ESCs isolated from human endometrial tissues remained untreated (D0), or decidualized for 4 days (D4) and 8 days (D8) in the presence of 8-bromo-cAMP and progesterone. RESULTS Among the epigenetic modifications examined (DNA methylation, H3K27ac, H3K9me3 and H3K27me3), the H3K27ac patterns changed most dramatically, with a moderate correlation with gene expression changes, upon decidualization. Subsets of up- and down-regulated genes upon decidualization were associated with reciprocal changes of H3K27ac and H3K27me3 modifications at their promoter region, and were enriched with genes essential for decidualization such as WNT4, ZBTB16, PROK1 and GREB1. CONCLUSION Our dataset is useful to further elucidate the molecular mechanisms underlying decidualization.

Abstract
AIM Since 2014, Japan Society of Gynecologic and Obstetric Endoscopy and minimally invasive therapy (JSGOE) conducted a nationwide survey on gynecologic endoscopic surgery. We aimed to evaluate the current status and complications associated with endoscopic surgery by Japan gynecologic and obstetric endoscopy-database registry system (JOE-D). METHODS Electrical medical records concerning the endoscopic surgery were generated from the daily use of reporting system. The subjects were all patients who underwent gynecologic endoscopic surgery. In addition to assessment of actual numbers, diagnosis, and operative methods, adverse events were registered. RESULTS Total 203 970 patients performed laparoscopic, hysteroscopic and falloposcopic surgery for 3 years, 2014-2016. The numbers of endoscopic surgeries conducted in 2016 were increased more than 67 000, 13 000 or 450 cases, respectively. Incidence rates of complications involving these three types of surgeries in each year were approximately 3.1%. Incidences of intraoperative complications were relatively high in malignant diseases, laparoscopic-assisted vaginal hysterectomy (LAVH) and myomectomy (LAM). In total laparoscopic hysterectomy/laparoscopic hysterectomy (TLH/LH) performed from 2014 to 2016, ureteral injury as intra and postoperative complication occurred in 0.35%. In the past 3 years, the rates of vascular injury, urinary tract, and bowel injury as intraoperative complications caused by laparoscopic surgery were approximately 0.1%. In the hysteroscopic surgery, the rates of total intra- and postoperative complications were 0.78%. CONCLUSION We exhibited the current status by the nationwide survey of gynecologic endoscopic surgery all over Japan. Severe intra or postoperative complications were identified over the 3 years at a rate of 0.04%.

Abstract
PURPOSE To investigate the impact of adenomyosis on the complications and outcomes of pregnancy in Japan. METHODS We carried out a multicenter retrospective questionnaire survey. A questionnaire regarding pregnancy complications and the outcomes of pregnancy was sent to 725 facilities. RESULTS Data were obtained on the cases of 272 pregnant women with adenomyosis from 65 facilities. The complications of pregnancy included miscarriage before 12 weeks of pregnancy (14.8%), miscarriage after 12 weeks of pregnancy (9.9%), preterm delivery (24.4%), fetal growth restriction (11.8%), pregnancy-induced hypertension (9.9%), intrauterine infection (7.3%), and cervical incompetency (5.3%). The rates of pregnancy complications in the three groups classified according to pretreatment for adenomyosis (no pretreatment, medication, surgery) did not differ to a statistically significant extent. The rates of miscarriage (>12 weeks) and cervical incompetency increased according to the size of the adenomyosis. The rates of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis were higher than that in patients with focal-type adenomyosis. CONCLUSIONS Our results show that the increased size and diffuse type of adenomyosis are associated with adverse pregnancy outcome. We should be aware of the higher incidence of pregnancy-induced hypertension and uterine infection in patients with diffuse-type adenomyosis.

Abstract
Background/Aims: Despite the benefits of laparoscopic surgery, which is being performed with increasing frequency, complications that do not occur during laparotomy are sometimes encountered. Such complications commonly occur during the initial trocar insertion, making this a procedural step of critical importance. Methods: In 2002, we experienced, upon initial trocar insertion, a serious major vascular injury (MVI) that led to hemorrhagic shock, and we thus modified the conventional closed entry method to an approach that we have found to be safe. We began developing the method by first measuring, in a patient undergoing laparoscopic cystectomy, the distance between the inner surface of the abdominal wall and the anterior spine when the abdominal wall was lifted manually for trocar insertion and when it was lifted by other methods, and we determined which method provided the greatest distance. We then devised a new approach, summarized as follows: The umbilical ring is elevated with Kocher forceps. The umbilicus is everted, and the base is incised longitudinally. This allows penetration of the abdominal wall at its thinnest point, and it shortens the distance to the abdominal cavity. A bladeless trocar (Step trocar) is used to allow insertion of the Veress needle. We began applying the new entry technique in July 2002, and by December 2014, we had applied it to 9676 patients undergoing laparoscopic gynecology surgery. Results: All entries were performed successfully, and no MVI occurred. The umbilical incision often resulted in an umbilical deformity, but in a questionnaire-based survey, patients generally reported satisfaction with the cosmetic outcome. Conclusion: A current new approach provides safe outcome with a minor cosmetic problem.

Abstract
Aim A multicenter, retrospective survey was conducted in order to investigate the current clinical status of adenomyosis in Japan. Methods The questionnaires covered the management of infertile women with adenomyosis and the outcomes of infertility treatment in women with adenomyosis. The questionnaires were sent to 1149 facilities in Japan. Results The data were obtained on 535 infertile women with adenomyosis from 190 facilities. Regarding management, infertility treatment was performed without pretreatment for adenomyosis in 37 facilities, after medication in eight facilities, and after an operation in four facilities. Management policies were not established in 106 facilities. Regarding outcomes, the pregnancy rate was 41.7% and the abortion rate was 29.8%. Eighty‐five patients received medication and 89 patients underwent surgery as a pretreatment before infertility treatment, while 361 patients had no pretreatment. In relation to the type of adenomyosis, 162 patients had the focal type and 336 patients had the diffuse type. The pregnancy rate and abortion rate were not affected by pretreatment or the type of adenomyosis. Conclusion The management policy for infertile women with adenomyosis has not been established. The pregnancy rate of infertility treatment is about 40%. There were no data to suggest that medication or surgery as a pretreatment for adenomyosis increased the pregnancy rate in infertile women.

Abstract
Upon breaching of the endometrial surface epithelium, the implanting embryo embeds in the decidualizing stroma. Retinoic acid (RA), a metabolite of vitamin A, is an important morphogen during embryonic and fetal development, although the role of the RA pathway in the surrounding decidual cells is not understood. Here we show that decidual transformation of human endometrial stromal cells (HESCs) results in profound reprogramming of the RA signaling and metabolism pathways. Differentiating HESCs downregulate the intracellular carrier proteins CRABP2 and FABP5, responsible for transfer and binding of RA to the nuclear receptors RAR and PPARβ/δ, respectively. Furthermore, the expression of RAR, the receptor that mediates the pro-apoptotic effects of RA, was also inhibited. By contrast, PPARβ/δ, which transduces the differentiation responses of RA, was upregulated. Decidualization was also associated with increased expression of retinol-binding protein 4 (RBP4) and various enzymes involved in the metabolism of RA and its precursor, retinaldehyde (Rald), including CYP26A1, DHRS3, and RDH12. Exposure of differentiating HESCs to RA or Rald reversed the inhibition of the CRABP2-RAR pathway, perturbed the expression of decidual marker genes and triggered cell death. Taken together, the data demonstrate that decidualizing HESCs silence RA signaling by downregulating key cytoplasmic binding proteins and by increasing retinoid metabolism. However, excessive RA exposure is toxic for decidual cells and triggers a response that may lead to pregnancy failure.

Abstract
Background Ovarian endometriomas affect a substantial proportion of women of reproductive age who may have a potential risk of diminished ovarian reserve (DOR) after ovarian cystectomy. Here, we investigated the risk factors for pre-surgical DOR in patients with ovarian endometriomas and for DOR after laparoscopic ovarian cystectomy for endometriomas and evaluated the feasibility of the pre-surgical prediction of post-surgical DOR based on the Bologna criteria. Methods A total of 143 patients with ovarian endometriomas who underwent laparoscopic cystectomy from January 2009 to May 2015 at our hospital were prospectively enrolled and evaluated. Serum anti-Müllerian hormone (AMH) concentrations were measured pre-surgically and at 3 and 6 months after surgery. In accordance with the Bologna criteria, the patients whose AMH concentrations were <1.1 ng/mL before surgery and 3 or 6 months after surgery were classified into pre- and post-surgical adverse DOR (aDOR) groups, respectively. Results Thirty-one (21.7 %) of 143 patients were classified as pre-surgical aDOR. Patient age and serum follicle-stimulating hormone level were significantly positively correlated with pre-surgical aDOR [odds ratios (ORs), 1.26 and 1.16; p < 0.001 and p = 0.003, respectively]. Among the remaining 112 patients, 38 patients (33.9 %) had post-surgical aDOR 3 and 6 months after surgery. Bilateral cystectomy was positively correlated with post-surgical aDOR (at 3 months: OR, 4.7; p = 0.001; at 6 months: OR, 3.71; p = 0.006); conversely, pre-surgical serum AMH concentrations were negatively correlated with post-surgical aDOR (at 3 months: OR, 0.65; p = 0.005; at 6 months: OR, 0.43; p < 0.001). The optimal cut-off point of pre-surgical AMH concentrations for predicting aDOR at 3 and 6 months in the patients undergoing unilateral cystectomy was 2.1 ng/mL. In contrast, the optimal cut-off points at 3 and 6 months in the patients undergoing bilateral cystectomy were 3.0 and 3.5 ng/mL, respectively. Conclusions Our data suggest that the pre-surgical serum AMH concentrations and bilateral cystectomy are significant factors for the risk of aDOR following surgery and that predicting post-surgical aDOR according to the Bologna criteria could be feasible using pre-operative measurements of serum AMH concentrations.

Abstract
We aimed to improve the efficiency of isolating endometrial epithelial and stromal cells (EMECs and EMSCs) from the human endometrium. We revealed by immunohistochemical staining that the large tissue fragments remaining after collagenase treatment, which are usually discarded after the first filtration in the conventional protocol, consisted of glandular epithelial and stromal cells. Therefore, we established protease treatment and cell suspension conditions to dissociate single cells from the tissue fragments and isolated epithelial (EPCAM-positive) and stromal (CD13-positive) cells by fluorescence-activated cell sorting. Four independent experiments showed that, on average, 1.2 × 10(6) of EMECs and 2.8 × 10(6) EMSCs were isolated from one hysterectomy specimen. We confirmed that the isolated cells presented transcriptomic features highly similar to those of epithelial and stromal cells obtained by the conventional method. Our improved protocol facilitates future studies to better understand the molecular mechanisms underlying the dynamic changes of the endometrium during the menstrual cycle.

Abstract
Gastric adenocarcinoma of fundic gland type [chief cell predominant type; (GA-FD-CCP)] is a rare gastric cancer variant arising from non-atrophic mucosa without Helicobacter pylori infection in the upper third portion of the stomach. GA-FD-CCP originates deep in the mucosal layer; hence, endoscopic lesion detection is often difficult at an early stage because of a minimal change in the mucosal surface. Here we present a 66-year-old man with an early stage of GA-FD-CCP showing characteristic endoscopic features. Esophagogastroduodenoscopy demonstrated a flat, slightly reddish area with black pigment dispersion and irregular micro-surface structure at the gastric fornix. The tumor was resected by endoscopic submucosal dissection and was pathologically diagnosed as GA-FD-CCP. Prussian blue staining revealed that the black pigment was a hemosiderin deposition. We reported a rare case of successfully treated GA-FD-CCP with black pigmentation that aided in early lesion detection.

Abstract
Background Myomectomy is now often performed laparoscopically rather than by laparotomy to alleviate the risk of postoperative adhesions and reduce postoperative pain. However, intracorporeal knot-tying under direct laparoscopy is difficult and requires proficiency. We conducted a retrospective study comparing the results of a long unidirectional barbed suturing technique (with V-Loc180 suture) and the results of conventional suturing as applied to laparoscopic myomectomy. Methods In women who underwent laparoscopic myomectomy in our university hospital between January 2011 and April 2013, uninterrupted suturing of 2 or more layers was performed. These women were divided into 2 groups according to the method of suturing: those in whom standard absorbable sutures were used (group P, n =42) and those in whom our suturing technique was used (group V, n =41). Patient characteristics and surgical variables were compared between the 2 groups. Results No significant between-group difference was observed in age (p = .975), body mass index (p = .778), GnRHa administration (p = .059), intraoperative vasopressin dose (p = .364), intraoperative blood loss (73.8 ± 64.1 vs. 59.3 ± 54.0 mL, respectively; p = .199), myoma mass (212.6 ± 133.3 vs. 208.3 ± 198.4 g, respectively; p = .134), ΔHb (p = .517), or postoperative hospital stay (p = .314). Operation time (mean ± SD) was significantly shorter for group V (71.2 ± 22.9 minutes; range, 28.0–110.0 minutes; p < .001) than for group P (94.4 ± 27.2 minutes; range, 53.0–165.0 minutes). No patient required intraoperative transfusion or conversion to laparotomy. Conclusions Our suturing technique exploits the features of unidirectional barbed sutures and can be used in the same way as the conventional method when performing continuous suturing for laparoscopic myomectomy. Our data suggest that operation time can be reduced by as much as 25% with this new technique.

Abstract
OBJECTIVE To investigate the incidence of port-site adhesions following use of radially expanding trocars (RETs) at laparoscopic myomectomy by observation via second-look laparoscopy (SLL). METHODS In a retrospective study, data from patients who underwent SLL after laparoscopic myomectomy between January 2007 and June 2012 at Juntendo University Hospital, Tokyo, were assessed for the incidence of port-site adhesions forming below RET incisional scars when fascial and peritoneal defects had not been closed. RESULTS During the study period, 554 patients underwent SLL, and 2176 incisional scars were examined. Adhesions were detected in 15 patients (2.8%); thus, the incidence of port-site adhesions under scars was 0.7% (15/2176). Among these 15 patients, the wounds with adhesions were located as follows: 6 (1.1%) under the umbilical scar, 5 (0.9%) under the right lower abdominal scar, 2 (0.4%) under the left upper abdominal scar, and 2 (0.4%) under the left lower abdominal scar. According to multiple regression analysis, the duration of laparoscopic myomectomy was positively associated with port-site adhesions (odds ratio, 1.79; 95% confidence interval, 1.09-2.94; P=0.02). CONCLUSION The present data suggest that the incidence of port-site hernias and adhesions under RET incisional scars is low despite the non-closure of fascial and peritoneal defects.

Abstract
Development of targeted therapy for hepatocellular carcinoma (HCC) remains a major challenge. We have recently identified an elevated expression of the fifth subunit of COP9 signalosome (CSN5) in early HCC as compared to dysplastic stage. In the present study, we explored the possibility of CSN5 being a potential therapeutic target for HCC. Our results show that CSN5 knockdown by small interfering (si) RNA caused a strong induction of apoptosis and inhibition of cell cycle progression in HCC cells in vitro. The downregulation of CSN5 was sufficient to interfere with CSN function as evidenced by the accumulation of neddylated Cullin1 and changes in the protein levels of CSN controlled substrates SKP2, p53, p27 and NF-kB, albeit to a different degree depending on the HCC cell line, which could account for the CSN5 knockdown phenotype. The transcriptomic analysis of CSN5 knockdown signature showed that the anti-proliferative effect was driven by a common subset of molecular alterations including downregulation of CDK6 and ITGB1, which were functionally interconnected with key oncogenic regulators MYC and TGFβ1 involved in the control of proliferation, apoptotic cell death and HCC progression. Consistent with microarray analysis, western blotting revealed that CSN5 depletion increased phosphorylation of Smad 2/3, key mediators of TGFβ1 signaling, decreased the protein levels of ITGB1, CDK6, and cyclin D1 and caused reduced expression of anti-apoptotic Bcl-2 while elevating the levels of pro-apoptotic Bak. A chemically modified variant of CSN5 siRNA was then selected for in vivo application based on the growth inhibitory effect and minimal induction of unwanted immune response. Systemic delivery of the CSN5 3/8 variant by stable-nucleic-acid-lipid-particles (SNALP) significantly suppressed the tumor growth in Huh7-luc+ orthotopic xenograft model. Taken together, these results indicate that CSN5 plays a pivotal role in HCC pathogenesis and maybe an attractive molecular target for systemic HCC therapy.
