Seasonal Serum 25(OH) Vitamin D Level and Reproductive or Immune Markers in Reproductive-Aged Women with Infertility: A Cross-Sectional Observational Study in East Japan.

Several studies have reported that vitamin D may modify human reproductive functions; however, the results are conflicting. We aimed to comprehensively evaluate serum vitamin D levels and examine the relationship between serum vitamin D levels and ovarian reserve markers, and immune markers of implantation, in reproductive-aged Japanese women with infertility.in reproductive-aged women with infertility. This cross-sectional, single-center study included reproductive-aged women who underwent preconception screening for fertility. Serum vitamin D levels and reproductive and immune markers were measured. Standard and advanced statistical techniques were used. We observed a statistically significant difference in the seasonal and monthly 25(OH) vitamin D levels; the 25(OH) vitamin D level during winter was the lowest among all seasons. However, there was no linear correlation between 25(OH) vitamin D levels and ovarian reserve markers, such as follicle-stimulating hormone and anti-Müllerian hormone, or the Th1/Th2 cell ratio, which is used as an implantation-related immunological marker. In this large-scale study, we evaluated the serum 25(OH) vitamin D concentration in reproductive-aged women with infertility in Japan; however, there was no association between reproductive function and vitamin D levels.

Impact of Homocysteine as a Preconceptional Screening Factor for In Vitro Fertilization and Prevention of Miscarriage with Folic Acid Supplementation Following Frozen-Thawed Embryo Transfer: A Hospital-Based Retrospective Cohort Study.

Homocysteine is an amino acid naturally produced in the body and metabolized via the methionine cycle. High homocysteine levels can increase the risk of infertility and pregnancy complications, such as preeclampsia, preterm delivery, miscarriage, and low birth weight. Preconceptional homocysteine levels may be reduced by taking folic acid supplements to reduce the risk of such complications. This cross-sectional, hospital-based study was conducted to examine the role of homocysteine in 1060 infertile women with a history of IVF/intracytoplasmic sperm injection (ICSI) failure. We analyzed whether folic acid intervention altered homocysteine levels and influenced reproductive outcome. We found that a higher homocysteine level was statistically associated with a lower fertilization rate in patients with a history of IVF/ICSI failure. There was an inverse relationship between homocysteine levels and serum 25(OH)VD, and a trend towards lower anti mullerian hormone in the group with higher homocysteine levels. This is the first interventional study to identify that folic acid supplementation improved pregnancy outcomes following freeze embryo transfer (FET) in women with a history of FET failure by monitoring the reduction in homocysteine levels. Therefore, folic acid supplementation and homocysteine level monitoring may constitute a novel intervention for improving IVF/ICSI pregnancy outcomes.

Effect of a web-based fertility preservation training program for medical professionals in Japan.

BACKGROUND: Our web-based training program called "Educating Medical Professionals about Reproductive Issues in Cancer Healthcare" aims to help healthcare professionals communicate promptly with patients and survivors who are adolescents and young adults, with information pertinent to reproductive health issues such as the risk of infertility and fertility preservation. METHODS: The study participants were professional healthcare providers, including physicians, nurses, pharmacists, social workers, midwives, psychologists, laboratory technicians, genetic counselors, and dieticians. Pre- and post- and 3-month follow-up tests consisting of 41 questions were administered to measure changes in knowledge and confidence. The participants also received a follow-up survey that covered confidence, communication techniques, and practice habits. A total of 820 healthcare providers participated in this program. RESULTS: The mean total score from the pre-test to the post-test grew significantly (p < 0.01), and participants' self-confidence increased. In addition, there was a change in the behavior of healthcare providers, who began asking about patients' marital status and parity. CONCLUSION: Our web-based fertility preservation training program improved knowledge and self-confidence regarding fertility preservation issues among healthcare providers caring for adolescents and young adult cancer patients and survivors.

An online survey on coping methods for genitourinary syndrome of menopause, including vulvovaginal atrophy, among Japanese women and their satisfaction levels.

BACKGROUND: This study aimed to explore the current situation and existing issues regarding the management of vulvovaginal atrophy (VVA) or the genitourinary syndrome of menopause (GSM). A nationwide web-based questionnaire survey was conducted among 1,031 Japanese women aged 40 years or older. MATERIALS AND METHODS: Eligible women were asked to complete a questionnaire about how they dealt with their symptoms and how satisfied they were with their coping methods. RESULTS: Of those highly conscious of their GSM symptoms (n = 208; 20.2%), 158 had sought medical consultation (15.3%), with only 15 currently continuing to seek consultation (11.5%). Of the specialties consulted, gynecology was the most frequently consulted (55%). Furthermore, those unwilling to seek medical consultation despite their symptoms accounted for the greatest proportion (n = 359; 34.8%), with 42 (23.9%) having never sought consultation. Topical agents, e.g., steroid hormone ointments/creams, were the most frequent treatments provided by the clinics (n = 71; 40.3%), followed by oral and vaginal estrogens (n = 27; 15.5%), suggesting that estrogen therapy was not the first choice of treatment at the clinics. While 65% of patients treated at the clinics reported satisfaction with the treatments, this was inconsistent with the fact that many were reported to have remained untreated and very few continued with treatment. CONCLUSIONS: Survey results suggest that GSM, including VVA, remains underdiagnosed and undertreated in Japan. Medical professionals should deepen their understanding of GSM and raise their level of care to select the appropriate treatment for the condition.

Successful Pregnancy and Delivery at Term Following Intravenous Immunoglobulin Therapy with Heparin for Unexplained Recurrent Pregnancy Loss Suspected of Immunological Abnormalities: A Case Report and Brief Literature Review.

About 60% of cases of recurrent pregnancy loss have unexplained etiology. Immunotherapy for unexplained recurrent pregnancy loss is still unestablished. A 36-year-old woman, not obese, had a stillbirth at 22 gestational weeks and a spontaneous abortion at 8 weeks. She had been examined for recurrent pregnancy loss at previous clinics with no significant findings. When she visited our clinic, a hematologic test showed a Th1/Th2 ratio imbalance. Ultrasonography, hysteroscopy, and semen analysis showed no abnormalities. She successfully conceived by embryo transfer in hormone replacement therapy cycle. However, she had a miscarriage at 19 weeks. The baby had no deformities, but a chromosomal test was not performed, according to the parents' will. The placenta pathologically suggested hemoperfusion problems. Her and her husband's chromosomal tests showed normal karyotypes. Other examinations revealed a repeated Th1/Th2 ratio imbalance and a high resistance index of uterine radial artery blood flow. She was administered low-dose aspirin, intravenous immunoglobulin, and unfractionated heparin after the second embryo was transferred. Her baby was healthily born by cesarean section at 40 weeks. Intravenous immunoglobulin therapy can be a choice for recurrent miscarriage without risk factors because it has clinically beneficial influences on the patient's immunological aberration.

A Nationwide Survey Aimed at Establishing an Appropriate Long-Term Storage and Management System for Fertility Preserving Specimens in Japan.

Purpose: The demand for fertility preservation continues to grow as cancer treatment outcomes improve. The specimen storage period is longer for fertility preservation than for conventional fertility treatment; therefore, a robust management system for stored specimens is required. We conducted the first national survey in Japan on the management of cryopreserved specimens in fertility preservation facilities. Methods: Questionnaires were mailed to 130 fertility preservation facilities. Primary outcomes included the official position of the storage manager, support system in case of facility closure, disaster countermeasures, management and operating system for liquid nitrogen storage containers, preservation costs, and method to confirm the intention to continue storage. Results: The response rate was 63.8%. The facility director most commonly functioned as the storage manager (59.0%). In case of facility closure, 20.5% had an approved transfer site; 59.0% had not made any decisions. In the management of liquid nitrogen containers, 83.1% regularly replenished the liquid nitrogen, 65.1% regularly checked the amount, and 16.9% had alarm monitoring systems. Regarding disaster countermeasures, 70.9% had taken measures to protect specimens. Conclusion: This survey revealed issues such as disparities among facilities regarding long-term specimen storage systems. Accordingly, management standards for fertility preservation facilities should be established.

Current Status and Issues of the Japan Oncofertility Registry.

Purpose: Fertility preservation (FP) is becoming increasingly common among child, adolescent, and young-adult (CAYA) patients with cancer. However, Japan has long lacked definite estimates of utilization rates for FP services among CAYA patients with cancer, and little is known about disease/FP outcomes among users. Therefore, the Japan Society for Fertility Preservation (JSFP) launched the Japan Oncofertility Registry (JOFR) in 2018 and started the online registration of information regarding primary disease, FP, and data on prognosis and pregnancy outcomes. This study reports the analytical results of FP data registered in the JOFR as of 2021. Methods: Data about patients' primary disease(s), treatment courses, cancer and pregnancy outcomes, and specific procedures were extracted from the JOFR and analyzed. Results: In 2021, 1244 patients received counseling or treatment related to FP (540 males, 704 females). While the numbers of males in each age group were approximately equal, most females were aged between 31 and 40 years. In total, 490 male and 540 female patients underwent FP procedures. Leukemia, testicular cancer, and malignant lymphoma accounted for the majority of male cases seeking treatment, whereas breast cancer was the primary disease in two-thirds of the females. Since 1999, 395 patients have accumulatively experienced subsequent pregnancy. Conclusions: As of January 2022, >7000 cases from >100 fertility facilities have been registered in the JOFR. In the future, maintaining JOFR to disseminate information on cancer prognoses, pregnancy rates, and other oncofertility outcomes is expected to drive further expansion of oncofertility services in Japan.

Pregnancy outcomes among female childhood, adolescent, and young adult cancer survivors assessed using internet-based nationwide questionnaire surveys in Japan.

OBJECTIVE: Female cancer survivors planning to become pregnant are concerned about the impact of cancer treatment on their ability to maintain normal pregnancy and the negative impact on their offspring. However, studies on the pregnancy outcomes of cancer survivors in Japan are limited. Therefore, this study aimed to investigate the pregnancy outcomes of female cancer survivors by comparing them with women without a history of malignant tumors in Japan. METHODS: This cross-sectional study included 3308 subjects, based on an internet-based questionnaire (self-reported) survey conducted in Japan. Differences in pregnancy outcomes, including multiple pregnancies, stillbirth, preterm birth (PTB), and infant birthweight, between cancer survivors and subjects without a history of malignant tumors, were evaluated using a generalized linear mixed-effects model with adjustment for possible confounding factors. RESULTS: Of 3308 subjects included in this study, 629 (19.0%) were cancer survivors, among whom cervical (40.4%), breast (19.1%), and thyroid (7.0%) malignancies were most frequent. 71 (2.2%) and 53 (1.6%) participants had a history of multiple pregnancies and stillbirth, respectively; 385 (11.8%), 179 (5.5%), and 137 (4.2%) participants, respectively, had histories of PTB at less than 37, 34, and 32 weeks of gestation. Further, 302 (10.7%), 326 (11.6%), and 330 (11.7%) participants delivered to low birthweight (LBW), small-for-gestational-age (SGA), and large-for-gestational-age (LGA) infants, respectively. Subjects with a history of cervical or breast cancers had significantly higher odds of PTB at <37 weeks of gestation (adjusted odds ratios [ORs], 1.87 [95% CI: 1.25-2.81] and 2.61 [95% CI: 1.77-3.86], respectively), preterm LBW infants (adjusted ORs, 2.70 [95% CI: 1.39-5.24] and 2.76 [95% CI: 1.03-7.38], respectively), and LGA infants (1.98 [95% CI: 1.36-2.89] and 1.99 [95% CI: 1.14-3.49], respectively), compared to those without a history of a malignant tumor. Subjects with a history of thyroid cancer had significantly higher odds of stillbirth (adjusted OR, 5.11 [95% CI: 1.11-23.5]). CONCLUSION: Cancer survivors had a higher risk of adverse pregnancy outcomes than those without a history of malignant tumors in Japan. Healthcare providers should consider the high likelihood of adverse pregnancy outcomes during preconception counseling for cancer survivors.

A case of discrepancy between three ERA tests in a woman with repeated implantation failure complicated by chronic endometritis.

BACKGROUND: Endometrial receptivity array (ERA) is used to determine the timing of embryo transfer (ET) synchronized with the window of implantation (WOI). The effectiveness and evaluation of ERAs in women with recurrent implantation failure remain controversial. We report the case of a patient with recurrent implantation failure that raises the issue of reproducibility of ERA tests. CASE REPORT: A 36-year-old Japanese woman with secondary infertility who had previously given birth failed to conceive after three frozen-thawed embryo transfer (FET) cycles. An ERA test was conducted to confirm the WOI. The first ERA test was performed 125 h after progesterone exposure. The laboratory reported that the endometrium was in a non-receptive (post-receptive) phase, and recommended retesting 101 h after progesterone exposure. A simultaneous chronic endometritis (CE) test showed a score of 3. After the antibiotics administration to treat CE, the second ERA test was performed after 101 h of progesterone exposure. The laboratory reported that the endometrium had not reached the WOI and estimated the WOI to be 113 ± 3 h after progesterone exposure. The third ERA test was performed 113 h after progesterone exposure. The laboratory reported that the endometrium was in a non-receptive (pre-receptive) phase and estimated the WOI to be 137 ± 3 h after progesterone exposure. A CE test performed at the same time as the second and third ERA tests showed a score of 1 for the collected endometrium. According to the third ERA test results, the vitrified-warmed blastocyst was transferred at 137 h of progesterone exposure. Pregnancy was achieved and the patient had an uncomplicated vaginal delivery at 39 weeks. One year later, another pregnancy was achieved after FET at 137 h of progesterone exposure, and the patient delivered at 33 weeks due to an unexpected membrane rupture. CONCLUSION: Because the results of the ERA test may vary in the presence of CE, CE should be diagnosed simultaneously with or before conducting ERA tests. If CE is diagnosed, ERA testing should be performed after treatment with antimicrobials or other drugs.

Laparoscopic Adenomyomectomy under Real-Time Intraoperative Ultrasound Elastography Guidance: A Case Series and Feasibility Study.

BACKGROUND: This study aimed to examine the clinical characteristics of 11 patients undergoing laparoscopic adenomyomectomy guided by intraoperative ultrasound elastography and this technique's feasibility. PATIENTS AND METHODS: Eleven patients undergoing laparoscopic adenomyomectomy using ultrasound elastography for adenomyosis at Kawasaki Medical School Hospital in Okayama, Japan between March 2020 and February 2021 were enrolled. Operative outcomes included operative time, operative bleeding, resected weight, operation complications, percent change in hemoglobin (Hb) values, and uterine volume pre- and postoperatively. Dysmenorrhea improvement was evaluated by changes in visual analog scale (VAS) scores pre- and 6- and 12-months postoperatively. RESULTS: The median operative time and bleeding volume was 125 min (range, 88-188 min) and 150 mL (10-450 mL), respectively. The median resected weight was 5.0 g (1.5-180 g). No intraoperative or postoperative blood transfusions or perioperative complications were observed. The median changes in uterine volume, Hb value, and VAS score were -49% (-65 to -28%), -3% (-11 to 35%), and -80% (-100 to -50%), respectively. The median follow-up period post-surgery was 14 months (7-30 months). Adenomyosis recurrence was not observed in the patients during the follow-up period. CONCLUSIONS: Laparoscopic adenomyomectomy using ultrasound elastography guidance is minimally invasive and resects as many adenomyotic lesions as possible.

TRACP-5b/BAP Score After 3 Months of Treatment With Combined SERM/E2 Therapy Can Predict Changes in Lumbar Spine Bone Mineral Density After 1 Year of Treatment in Early Postmenopausal Osteopenia.

Although changes in bone mineral density (BMD) are important indexes in osteoporosis treatment, no markers are available to predict them. Given the importance of assessing the therapeutic windows of antiresorptives, we explored potential biomarkers of bone remodeling in patients receiving treatment for osteopenia. Postmenopausal women with osteopenia (defined as a lumbar BMD T-score <-1.0 standard deviation (SD) below that of a reference population but >-2.5 SD) were administered estradiol 1 mg/d and bazedoxifene 20 mg/d. After 3 months of treatment, we evaluated their ratio of serum bone-specific tartrate-resistant acid phosphatase to bone-specific alkaline phosphatase (TRACP-5b/BAP), which is widely used for evaluating bone turnover in postmenopausal patients with osteoporosis in Japan because their minimum significant changes are smaller than other bone turnover markers such as carboxy-terminal collagen cross-links (CTX) or N-terminal propeptide of type I procollagen (P1NP) and thus, accurately reflect bone turnover. After 1 year of treatment, we assessed changes in lumbar BMD. The cut-off TRACP-5b/BAP scores for a ≤-2% decrease and ≥2% increase in lumbar spine BMD were 38.4 and 29.0, respectively. The TRACP-5b/BAP scores were associated with significantly greater areas under the curve than the other evaluated parameters. These results suggest that the TRACP-5b/BAP score after 3 months of osteopenia treatment can predict changes in lumbar BMD after 1 year of treatment. Moreover, a receiver operating characteristic curve analysis of TRACP-5b/BAP scores after 3 months of antiresorptive therapy and percent changes in BMD at 1 year revealed that the TRACP-5b/BAP score, as an index of the balance between bone resorption and formation markers, has the potential to serve as a modulator of the anabolic window reflective of bone remodeling. This study's findings also suggested a role for TRACP-5b/BAP score as a predictor of a non-response to antiresorptive therapy, thus offering health economic implications for osteoporosis treatment. © 2022 The Authors.

Successful laparoscopic management of acute abdominal pain due to spontaneous rupture of subserosal vessels overlying a uterine fibroid: a case report and surgical video.

BACKGROUND: Acute abdomen comprises several emergencies. Hemoperitoneum associated with uterine fibroids, which can present as acute abdominal pain, is rare and difficult to diagnose. Especially, spontaneous hemorrhage from the rupture of the superficial vessels overlying a uterine fibroid is extremely rare, and its diagnosis and management have not been established. CASE PRESENTATION: We report a case of a 55-year-old woman who presented at our hospital with acute abdomen. After performing a computed tomography scan, we conducted a laparoscopic examination and diagnosed hemoperitoneum of ambiguous origin. We treated the patient surgically, performing a laparoscopic myomectomy to remove the origin of the hemorrhage. The patient recovered well. CONCLUSIONS: We report a case of hemoperitoneum of ambiguous origin that was diagnosed laparoscopically and treated by laparoscopic myomectomy to remove the origin of the hemorrhage. Surgeons should rapidly diagnose and manage acute abdominal pain in women with a history of uterine fibroids to prevent severe morbidity or even mortality. Therefore, laparoscopic surgery is recommended in patients with stable hemodynamics.

Robotic-assisted Total Hysterectomy with Low Pneumoperitoneal Pressure (6 mmHg) and Use of Surgical Plume Evacuator System to Minimize Potential Airborne Particles According to the Joint Statement on Minimally Invasive Gynecologic Surgery during the COVID-19 Pandemic: A Case Report from Japan.

We presented a case of uncontrolled genital bleeding caused by subserosal fibroid and treated by robotic-assisted hysterectomy during the coronavirus disease 2019 (COVID-19) pandemic. A 49-year-old woman had severe anemia with hypermenorrhea due to submucosal fibroid. Hysterectomy was deemed necessary to control genital bleeding. However, at that time, the number of confirmed COVID-19 cases has been increasing in Japan. Serious concerns have been raised about the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) dissemination during minimally invasive surgery due to pneumoperitoneum-associated aerosolization of particles. We tried to prevent the spread of surgical plume by performing surgery under low pneumoperitoneal pressure at 6 mmHg and by using an evacuation/filtration system. As a result, we successfully performed robotic-assisted hysterectomy with minimized risk of spreading surgical plume-containing aerosol particles into the operating room. It is essential to follow the guidelines issued by the relevant societies and act accordingly to reduce the risk of SARS-CoV-2 infection in medical settings while performing surgery. We hope that our experience will help prevent secondary cases of future SARS-CoV-2 infections.

A practical survey of fertility-preservation treatments in the startup phase in Japan.

AIM: The actual status of fertility preservation treatments in the startup phase in Japan was investigated as a basis for discussing future directions. METHODS: This study was conducted as "Research project to promote support of children and parenting 2016" which was supported by Ministry of Health in Japan with the approval of the institutional review board at St. Marianna University. Subjects of the survey were facilities registered with the Japan Society of Obstetrics and Gynecology as fertility preservation facilities, and facilities belonging to the Japan Association of Private Assisted Reproductive Technology Clinics and Laboratories. We provided questionnaires to survey both the medical care system and cases for which fertility preservation was implemented between 2006 and 2016. RESULTS: Responses were obtained from 68 facilities (of the 64, 59 [92.2%] responded to the questionnaire and 9 clinics cooperated). Many facilities limited the cryopreservation of oocytes and ovaries to patients 40-41 years old and the use of eggs to patients 44-45 years old. In the patient survey, 812 cases of oocyte cryopreservation and 201 cases of ovarian tissue cryopreservation were performed during study period. Breast cancer was the most indicated disease, with oocyte cryopreservation in the late 30s and ovarian tissue cryopreservation in the early 30s. Very few babies were born from fertility preservation, and no live birth cases of ovarian tissue cryopreservation were identified. CONCLUSIONS: Even from the early days, fertility preservation was implemented according to certain standards in Japan, but was characterized by a large variety of facilities.

Successful pregnancy and delivery after a vitrified-warmed embryo transfer in a woman with Kallmann syndrome: A case report and literature review.

Kallmann syndrome, a congenital disorder of idiopathic hypogonadotropic hypogonadism associated with anosmia, results in infertility because of anovulation. Assisted reproductive technology (ART) is considered when optimal ovulation induction therapy is difficult or when several cycles of ovulation induction therapy do not result in pregnancy. However, evidence is lacking regarding the optimal ART treatment for Kallmann syndrome. We report the case of a 33-year-old woman who successfully achieved pregnancy and delivery after ART treatment. At 29 years old, she was diagnosed with Kallmann syndrome due to hypothalamic amenorrhea and anosmia. At 33 years old, she revisited the hospital, desiring a child after one year of infertility. Due to anovulation, she was treated with gonadotropin therapy, but controlling follicular development was difficult, and thus ART treatment was initiated. The controlled ovarian stimulation (COS) protocol for ART treatment employed gonadotropins, recombinant follicular stimulating hormone/human menopausal gonadotropin plus human chorionic gonadotropin, to promote follicular growth. Four oocytes were retrieved, and two cleaved embryos were vitrified and cryopreserved. After vitrified-warmed embryo transfer of a morula stage embryo in a hormone replacement cycle, pregnancy was achieved but resulted in a miscarriage. A second oocyte retrieval was performed under the same COS; four oocytes were retrieved, and two cleaved embryos were vitrified and cryopreserved. Further, a pregnancy was achieved through the vitrified warmed embryo transfer. At 40 weeks and 6 days of gestation, a baby boy weighing 3,344 g with an Apgar score of 7/8 was delivered vaginally. The mother's postpartum course and neonate were free from adverse events. For women with Kallmann syndrome, ART treatment and selective embryo cryopreservation may be a reasonable and safe option.

Porous diaphragm syndrome presenting as hemothorax secondary to hemoperitoneum after laparoscopic myomectomy: A case report and literature review.

Porous diaphragm syndrome includes all pleural cavity conditions, including pleural effusion, hemothorax, or pneumothorax, that occur secondary to peritoneal cavity disorders through defects in the diaphragm. In this report, we describe the first known case of porous diaphragm syndrome presenting as hemothorax after laparoscopic myomectomy. A 46-year-old nulliparous woman underwent laparoscopic myomectomy for multiple fibroids. Eight hours after surgery, the patient developed exertional dyspnea followed by hemoptysis. Radiological diagnosis revealed massive hemothorax in the right thoracic cavity. Thoracoscopic findings showed the presence of small fenestrae at the center of the right diaphragm, which were repaired thoracoscopically. Hence, quick postoperative diagnosis resulted in successful treatment. In this case, porous diaphragm syndrome is believed to be caused by retention of intraoperative bleed and saline from intra-abdominal lavage, in the abdominal cavity. Porous diaphragm syndrome is a potential life-threatening condition that gynecological surgeons should consider in this era of laparoscopic surgery.

Trocar-site hernia following laparoscopic salpingo-oophorectomy in a middle-aged Japanese woman: an initial case report after 40 years of experience at a single center and a brief literature review.

BACKGROUND: In gynecology, the number of laparoscopic surgeries performed has increased annually because laparoscopic surgery presents a greater number of advantages from a cosmetic perspective and allows for a less invasive approach than laparotomy. Trocar site hernia (TSH) is a unique complication that causes severe small bowel obstruction and requires emergency surgery. Its use has mainly been reported with respect to gastrointestinal laparoscopy, such as for cholecystectomy. Contrastingly, there have been few reports on gynecologic laparoscopy because common laparoscopic surgeries, such as laparoscopic salpingo-oophorectomy, are considered low risk due to shorter operative times. In this study, we report on a case of a woman who developed a TSH 5 days postoperatively following a minimally invasive laparoscopic surgery that was completed in 34 min. CASE PRESENTATION: A 41-year-old woman who had undergone laparoscopic salpingo-oophorectomy 5 days previously presented with the following features of intestinal obstruction: persistent abdominal pain, vomiting, and inability to pass stool or flatus. A computed tomography scan of her abdomen demonstrated a collapsed small bowel loop that was protruding through the lateral 12-mm port. Emergency surgery confirmed the diagnosis of TSH. The herniated bowel loop was gently replaced onto the pelvic floor and the patient did not require bowel resection. After the surgical procedure, the fascial defect at the lateral port site was closed using 2-0 Vicryl sutures. On the tenth postoperative day, the patient was discharged with no symptom recurrence. CONCLUSIONS: The TSH initially presented following laparoscopic salpingo-oophorectomy; however, the patient did not have common risk factors such as obesity, older age, wound infection, diabetes, and prolonged operative time. There was a possibility that the TSH was caused by excessive manipulation during the tissue removal through the lateral 12-mm port. Thereafter, the peritoneum around the lateral 12-mm port was closed to prevent the hernia, although a consensus around the approach to closure of the port site fascia had not yet been reached. This case demonstrated that significant attention should be paid to the possibility of patients developing TSH. This will ensure the prevention of severe problems through early detection and treatment.

Ageing impairs restoration of endometrial blood flow impedance after laparoscopic myomectomy in infertile women with uterine fibroids.

The aim of this study was to evaluate temporal changes in endometrial blood flow after laparoscopic myomectomy (LM). Nineteen infertile women with uterine fibroids who underwent LM were included. The uterine radial artery resistance index (RA-RI) and recovery index were measured before and at 1 week and 3 months after LM. The median RA-RI at 1 week but not 3 months after LM was significantly higher than before. The median recovery indexes at 1 week and 3 months after LM were 14.3% and 1.3%, respectively. Although there was no significant correlation between the patient's age and recovery index at 1 week (r = 0.28, p = .24) after LM, a moderately significant correlation was observed at 3 months (r = 0.54, p = .002). In conclusion, the endometrial blood flow after LM changed over time, and recovery of blood flow was negatively correlated with patient age.IMPACT STATEMENTWhat is already known on this subject? Uterine blood flow is important for wound healing after myomectomy, but no studies have evaluated endometrial blood flow after myomectomy.What do the results of this study add? The endometrial blood flow impedance of RA-RI increased after LM and returned to before surgery at 3 months postoperatively. RA-RI recovery index negatively correlated with patient age.What are the implications of these findings for clinical practice and/or further research? The changes in endometrial blood flow impedance after myomectomy suggest that endometrial blood flow may be involved in wound healing at the enucleation site. The impairment of endometrial blood flow recovery after myomectomy due to increased age may provide a rationale for individualised wound healing after myomectomy. The measurement of endometrial blood flow may be useful in personalising the assessment of the waiting period for pregnancy after myomectomy.
