ABSTRACT
Background/Aim: Upper gastrointestinal obstruction is an extremely rare complication of primary ovarian cancer. We present a case of primary advanced ovarian cancer with gastroduodenal obstruction successfully managed with neoadjuvant chemotherapy (NAC) and conservative treatment. Case Report: A 60-year-old woman was referred to our hospital for advanced ovarian cancer with upper gastrointestinal obstruction. Computed tomography and endoscopy revealed severe duodenal obstruction caused by dissemination. NAC was initiated with conservative management using a nasogastric tube and total parenteral nutrition (TPN). She was able to eat and TPN was stopped after three months. Complete resection was achieved with interval debulking surgery (IDS) not involving pancreatoduodenectomy, which would have been necessary for primary debulking surgery. There were no serious postoperative complications. Conclusion: NAC with conservative management can improve upper gastrointestinal obstruction in patients with primary advanced ovarian cancer. Furthermore, IDS is expected to allow complete resection, avoiding highly invasive surgeries.
ABSTRACT
BACKGROUND: Ectopic pregnancy (EP) can be treated surgically or nonsurgically. In many countries, methotrexate is frequently used as a first-line medical treatment, and its effect is similar to that of surgery in selected patients. We aimed to investigate national trends in the treatment of EP in Japan. METHODS: We conducted a retrospective observational analysis between 2010 and 2020 using a nationwide claims database that included inpatient data. We identified female inpatients with EP aged 15 to 49 years old. We analysed year-to-year treatment trends for EP, as well as year-to-year trends in methotrexate administration, with a focus on the site of the pregnancy. Patients who received methotrexate were divided into two groups: Those with and those without surgery after methotrexate use. We compared the characteristics of these groups and calculated the methotrexate success rate. RESULTS: We identified 53,653 patients with EP. The proportion of patients undergoing surgery increased from 79% in 2010 to 83% in 2020, whereas the proportion of methotrexate therapy decreased from 8.1% in 2010 to 5.1% in 2020. Regarding methotrexate use for the site of the pregnancy, there was a significant downward trend in methotrexate therapy for tubal pregnancies. Notably, the methotrexate success rate was 84% during the study period. CONCLUSIONS: Surgery showed an increasing tendency over time, whereas methotrexate therapy showed a decreasing tendency for EP treatment in Japan. The efficacy of methotrexate in Japan was comparable to that observed in other countries.
Treatment for ectopic pregnancy includes surgical and non-surgical management. Medical treatment can be as effective as surgery in cases that meet certain criteria. Methotrexate, which is commonly employed as a medical treatment, is widely used in many countries outside Japan. However, reports on methotrexate therapy for ectopic pregnancy in Japan are limited, and the actual status of its use remains unknown. We investigated the treatment trends for ectopic pregnancy in Japan using nationwide inpatient data. The results demonstrated that surgeries increased from 79% in 2010 to 83% in 2020, while methotrexate therapy declined from 8.1% to 5.1%. Methotrexate therapy demonstrated an 84% success rate. Unlike many other countries, surgery became more prevalent while methotrexate therapy decreased for inpatients with ectopic pregnancy in Japan. The success rate of methotrexate in Japan was comparable to that in other countries. Thus, Japanese healthcare providers should consider using methotrexate therapy for appropriate cases and carefully choose the best treatment for each patient after discussing the treatment options with patients.

Accurately interpreting persistent, low human chorionic gonadotropin (hCG) levels is essential for managing gestational trophoblastic disease. Erroneous interpretation can lead to inappropriate interventions, including unnecessary chemotherapy or hysterectomy, or unjustified changes in chemotherapeutic regimens due to misidentification of a false-positive hCG as a true positive. The predominant etiology of phantom hCG is the presence of heterophilic antibodies. Consequently, screening for urine hCG is indispensable for its diagnosis because immunoglobulin is not generally present in urine. Here, we report about phantom hCG after a complete hydatidiform mole. Initial urine hCG evaluations were negative, although the serum hCG levels remained positive, leading to the diagnosis of phantom hCG. After subsequent delivery, urine hCG levels persisted at diminished levels. However, a different assay yielded negative hCG results for both serum and urine samples. The patient subsequently gave birth. The absence of hCG was consistently confirmed over five years.
ABSTRACT
Keratin-positive giant cell-rich tumor (KPGCT) is an extremely rare and recently described mesenchymal neoplasm that occurs in both soft tissue and bone, frequently found in young women. It has locally recurrent potential if incompletely excised but low risk for metastasis. KPGCT is histologically similar to conventional giant cell tumors of soft tissue but shows the presence of keratin-positive mononuclear cells. Interestingly, KPGCT also shares some morphological features with xanthogranulomatous epithelial tumors. These two tumors have recently been shown to harbor an HMGA2-NCOR2 fusion, arguing in favor of a single entity. Surgery is the treatment of choice for localized KPGCT. Therapeutic options for advanced or metastatic disease are unknown. This review provides an overview of the current knowledge on the clinical presentation, pathogenesis, histopathology, and treatment of KPGCT. In addition, we will discuss the differential diagnosis of this emerging entity.
ABSTRACT
Accurate diagnosis of partial hydatidiform moles (PHMs) is crucial for improving outcomes of gestational trophoblastic neoplasia. The use of short tandem repeat (STR) polymorphism analysis to distinguish between PHM and hydropic abortuses is instrumental; however, its diagnostic power has not been comprehensively assessed. Herein, we evaluated the diagnostic efficacy of STR in differentiating between PHM and hydropic abortus, thus providing an opportunity for early measurement of human chorionic gonadotropin for PHMs. We reviewed charts of STR polymorphism analysis performed on fresh villous specimens and patient blood samples using a commercial kit for 16 loci. The genetic classification of 79 PHMs was confirmed. STR was reliable in differentiating PHMs when at least 15 loci were available. Typically, PHMs are characterized by their triploidy, including two paternal and one maternal haploid contribution. In our sample, seven PHMs lacked the three-allelic loci, requiring fluorescence in situ hybridization (FISH) analysis to investigate imbalanced biparental conceptus and single-nucleotide polymorphism array analysis to reveal cytogenetic details. Of these PHMs, two, three, and one were identified as androgenetic/biparental mosaics (diploids), monospermic diandric monogynic triploids, and a typical dispermic diandric monogynic triploid, respectively. The remaining case was monospermic origin, but its ploidy details could not be available. Therefore, STR differentiated PHM from a biparental diploid abortus in most cases. However, PHM diagnosis may be compromised when STR is used as the sole method for cases displaying distinct cytogenetic patterns lacking the three-allelic loci, including androgenetic/biparental mosaicism. Therefore, FISH should be considered to confirm the diagnosis.

WHO Classification of Skin Tumors, fifth edition (2023) has newly described primary cutaneous NUT carcinoma; however, information on this cancer type remains scarce. Herein, we performed clinicopathologic and genetic analyses of 4 cases. Four elderly women (median age 77 y, range: 68 to 82 y) were included. The median tumor size was 12.5 (10 to 40 mm). Tumors were located on the scalp, temple, thigh, and palm. Two (50%) patients presented with regional lymph node metastases. Neither distant metastasis nor mortality was observed during patient follow-up of 10.5 (3 to 15) months. Sanger, panel DNA and whole-exome RNA sequencing revealed BRD3::NUTM1 (n=2) and BRD4::NUTM1 (n=2) fusions. Histology of BRD3 -rearranged tumors revealed an epidermal connection, relatively small tumor nests, and ductal or intracytoplasmic luminal formation, whereas that of BRD4 -rearranged tumors revealed large solid nests comprising discohesive tumor cells. NUT, cytokeratins, p63, EMA, TRPS1, c-MYB, CD56, and INSM1 were immunoexpressed to varying degrees in all (100%) tumors. Furthermore, diffuse SOX10 expression was common (3/4, 75%). The literature review of five previously described cases revealed women predominance, no recurrence, frequent BRD3::NUTM1 fusions, and histology of ductoglandular structures. Our study findings and literature suggest elderly women predominance, relatively frequent BRD3::NUTM1 fusions, histopathologic ductoglandular differentiation, absence of abrupt keratinisation, and a characteristic immunoprofile in primary cutaneous NUT carcinoma, unlike in that of other organ. No distant metastasis or disease-associated mortality was seen in all cases with limited follow-up.

Giant cell tumor of soft tissue (GCTST) is a locally aggressive mesenchymal neoplasm of intermediate malignancy that predominantly occurs in the superficial soft tissue of the extremities. It is histologically similar to a giant cell tumor of bone (GCTB) and shows a mixture of round to oval mononuclear cells and osteoclast-like multinucleated giant cells. Currently, immunohistochemistry plays a very limited role in the diagnosis of GCTST. Primary or secondary malignant GCTST has recently been described and tumors exhibiting high-grade histological features demonstrate higher rates of distant metastasis. GCTST lacks the H3-3A gene mutations that are identified in the vast majority of GCTBs, suggesting a different pathogenesis. Surgery is the standard treatment for localized GCTST. Incomplete surgical resection is usually followed by local recurrence. Radiation therapy may be considered when the close proximity of critical structures prevents microscopically negative surgical margins. The systemic treatment options for advanced or metastatic disease are very limited. This review provides an updated overview of the clinicoradiological features, pathogenesis, histopathology, and treatment for GCTST. In addition, we will discuss the differential diagnosis of this peculiar neoplasm.
ABSTRACT
AIM: In April 2020, the Japanese government introduced a Specific Medical Fee for managing secondary dysmenorrhea (SD). This initiative provided financial incentives to medical facilities that provide appropriate management of SD with hormonal therapies. We aimed to assess how this policy affects the management processes and outcomes of patients with SD. METHODS: Using a large Japanese administrative claims database, we identified outpatient visits of patients diagnosed with SD from April 2018 to March 2022. We used an interrupted time-series analysis and defined before April 2020 as the pre-introduction period and after April 2020 as the post-introduction period. Outcomes were the monthly proportions of outpatient visits due to SD and hormonal therapy among women in the database and the proportions of outpatient visits for hormonal therapy and continuous outpatient visits among patients with SD. RESULTS: We identified 815 477 outpatient visits of patients diagnosed with SD during the pre-introduction period and 920 183 outpatient visits during the post-introduction period. There were significant upward slope changes after the introduction of financial incentives in the outpatient visits due to SD (+0.29% yearly; 95% confidence interval, +0.20% to +0.38%) and hormonal therapies (+0.038% yearly; 95% confidence interval, +0.030% to +0.045%) among the women in the database. Similarly, a significant level change was observed after the introduction of continuous outpatient visits among patients with SD (+2.68% monthly; 95% confidence interval, +0.87% to +4.49%). CONCLUSIONS: Government-issued financial incentives were associated with an increase in the number of patients diagnosed with SD, hormonal therapies, and continuous outpatient visits.

OBJECTIVE: Therapy-related myeloid neoplasms (t-MNs) are often fatal and arise as late complications of previous anticancer drug treatment. No single-center case series has examined t-MNs in epithelial ovarian cancer (EOC). METHODS: All patients with EOC treated at Chiba University Hospital between 2000 and 2021 were included. We retrospectively analyzed the characteristics, clinical course, and outcomes of patients who developed t-MNs. RESULTS: Among 895 cases with EOC, 814 cases were treated with anticancer drugs. The median follow-up period was 45 months (interquartile range, 27-81) months. Ten patients (1.2%) developed t-MNs (FIGO IIIA in one case, IIIC in three, IVA in one, and IVB in five). Nine patients were diagnosed with myelodysplastic syndrome and one with acute leukemia. One patient with myelodysplastic syndrome developed acute leukemia. The median time from the first chemotherapy administration to t-MN onset was 42 months (range, 21-94 months), with t-MN diagnoses resulting from pancytopenia in four cases, thrombocytopenia in three, and blast or abnormal cell morphology in four. The median number of previous treatment regimens was four (range, 1-7). Paclitaxel + carboplatin therapy was administered to all patients, gemcitabine and irinotecan combination therapy to nine, bevacizumab to eight, and olaparib to four. Six patients received chemotherapy for t-MN. All patients died (eight cancer-related deaths and two t-MN-related deaths). None of the patients was able to restart cancer treatment. The median survival time from t-MN onset was 4 months. CONCLUSIONS: Patients with EOC who developed t-MN were unable to restart cancer treatment and had a significantly worse prognosis.

Ulipristal (UPA), a selective progesterone receptor modulator, has both agonistic and antagonistic effects on progesterone receptors. UPA suppresses ovulation by inhibiting the luteinizing hormone (LH) surge from the pituitary gland; however, the direct effect of UPA on ovarian tissue remains poorly studied. In the present study, we examined the effects of UPA on the ovaries of rats. Rats were treated for 28 days with UPA, and the effects of UPA on ovarian tissue were examined histologically and the expression of antioxidant genes and cell death markers were also investigated. UPA treatment increased the number of primordial follicles at each treatment group, primordial follicles increased at all dose levels, but the size/magnitude of the effect decreased with the increasing dose. The number of primary and antral follicles tended to increase with increasing UPA levels. Furthermore, the decrease in primary follicle number could be attributed to the exhaustion of follicles, but the examination of proliferation markers, oxidative stress markers, and cell death markers revealed no remarkable toxic effects on ovarian tissues. These results suggest that UPA treatment promotes follicle development at each stage but inhibits ovulation by suppressing the LH surge, resulting in an increase in atretic follicles or unruptured luteinized cysts. These results suggest that UPA may not have both toxic effects on the ovary and a direct local effect on ovarian follicles, but we should be careful about the effects of prolonged UPA treatment in patients with uterine fibroids on their future fecundity.

Background/Aim: Single-agent chemotherapy typically has curative outcomes in patients with low-risk gestational trophoblastic neoplasia (GTN). Although surgical intervention is a potential alternative, its efficacy in these patients remains unclear. This report describes a case in which surgical excision of a uterine polypoid lesion resolved chemotherapy-resistant low-risk GTN. Case Report: A 43-year-old patient received pulse actinomycin D treatment for post-molar low-risk GTN without extrauterine metastasis. However, the patient showed resistance to the chemotherapy regimen. There was no initial evidence of protrusion of GTN into the uterine cavity; however, a polypoid lesion grew into the uterine cavity during therapy. This growth was successfully excised via a transvaginal approach using forceps with minimal blood loss. There was a postoperative decrease in human chorionic gonadotropin levels, which ultimately reached the predetermined threshold without the need for changing the therapeutic protocol. Conclusion: Surgical resection should be considered a viable therapeutic strategy for uterine polypoid growth in chemotherapy-resistant low-risk GTN.
ABSTRACT
BACKGROUND: Endometriosis-related pain encompassing dysmenorrhea, dyspareunia, and chronic pelvic pain, reduces the quality of life in premenopausal women. Although treatment options for endometriosis alleviate this pain, approximately one-third of women still experience pain even after receiving treatment, indicating the need for novel approaches to pain relief in those women. The Angel Touch device (AT-04) is a portable magnetic fields irradiation device that incorporates a combination of mixed alternative magnetic fields at 2 kHz and 83.3 MHz. A phase III trial confirmed the efficacy and safety of AT-02, a prototype of AT-04, for pain relief in patients with fibromyalgia. METHODS: This is a phase III, multicenter, prospective, randomized, sham device-controlled, double-blind, parallel study. The participants will be premenopausal women aged > 18 years who have endometriosis-related pain with at least moderate severity. Considering dropouts, 50 participants have been deemed appropriate. Eligible women will be centrally registered, and the data center will randomly allocate them in a 1:1 ratio to the intervention and control groups. Women in the intervention group will receive electromagnetic wave irradiation generated by AT-04 and those who in the control group will wear a sham device for 16 weeks, and both groups will wear AT-04 for another 4 weeks. The primary outcome measure is the change in the Numeric Rating Scale score at 16 weeks compared with the baseline. Secondary outcome measures are efficacy for pelvic pain including dysmenorrhea and non-menstrual pain, and chronic pelvic pain not related to menstruation, dysmenorrhea, and dyspareunia, and improvement of quality of life during the study period. Safety will be evaluated by device defects and the frequency of adverse events. The study protocol has been approved by the Clinical Study Review Board of Chiba University Hospital, Chiba, Japan, and will be conducted in accordance with the principles of the Declaration of Helsinki and the Japanese Clinical Trials Act and relevant notifications. DISCUSSION: This study aims to develop a novel method of managing endometriosis-related pain. The AT-04 is an ultralow-invasive device that can be used without inhibiting ovulation, suggesting potential benefits to women of reproductive-age. Trial registration number Japan Registry of Clinical Trials (jRCTs032230278).
Endometriosis is a chronic inflammatory disorder that negatively impacts reproductive health via endometriosis-related pain, infertility, and endometriosis-associated ovarian cancer. Although current therapeutic options for endometriosis are effective for the endometriosis-related pain, approximately one-third of women still experience pain even after receiving treatment, indicating the need for novel approaches to pain relief in those women. This is the first randomized controlled trial to investigate the efficacy and safety of a novel portable pain management device, AT-04, that incorporates a combination of mixed alternating magnetic fields, for endometriosis-related pain. This is a multicenter, prospective, sham device-controlled, double-blind, parallel study. Enrolled women will have undergone standard hormonal treatment for endometriosis at baseline, and this allows for assessing whether the device remains effective when used in conjunction with existing treatment methods. The study also will explore the impact of AT-04 on reducing the size of ovarian endometriotic cysts that reflect the activity of endometriosis. The study reflects the strong desire by physicians to liberate women from the unbearable pain associated with endometriosis. The sole efficacy of AT-04 in treating endometriosis-related pain is difficult to evaluate as there is a possibility that menstrual cycles may influence the assessment of pain and quality of life. However, the study findings regarding the effectiveness of AT-04 for the treatment of endometriosis-related pain may benefit women with endometriosis who have pain that is not effectively relieved by other treatments. Consequently, it may contribute to the improvement of reproductive health within society.

AIM: To identify the symptoms and relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. METHODS: We retrospectively reviewed the charts of 125 women admitted to our intensive care unit because of postpartum hemorrhage between January 2011 and December 2021. Three women developed acute adrenal insufficiency. We investigated the total blood loss, shock status, consciousness level upon arrival, and intensive care provided to the women. We also analyzed the symptoms and laboratory data that led to the diagnosis of acute adrenal insufficiency. Continuous variables were presented by median (minimum-maximum). RESULTS: The medians and ranges of age, total blood loss, and shock index [heart rate/systolic blood pressure] on admission were 33.1 (17.2-45.3) years, 3351 (595-20 260) g, and 0.94 (0.55-2.94), respectively. Seven women were older than 40 years, 28 experienced >5000 g blood loss, 17 had shock index >1.5, 27 had impaired consciousness upon arrival, and 15 underwent hysterectomy. Women who developed acute adrenal insufficiency were <40 years old and had a bleeding volume of over 5000 g, impaired consciousness upon arrival, and had undergone hysterectomy. They had experienced lactation failure, presented with hyponatremia-related symptoms on postpartum days 8-9, experienced general malaise, headache, and impaired consciousness, and showed severe hyponatremia. CONCLUSIONS: Massive postpartum hemorrhage over 5000 g, impaired consciousness upon arrival, and hysterectomy as a hemostatic measure were relevant factors associated with acute adrenal insufficiency of early-onset Sheehan syndrome. Hyponatremia-related symptoms occurring after lactation failure are indicative of the onset of acute adrenal insufficiency.

OBJECTIVE: To quantitatively evaluate the effect of a booster vaccination dose against coronavirus disease 2019 (COVID-19) on menstrual cycle in a large-scale retrospective cohort study using a menstrual cycle tracking smartphone application (app). METHODS: Prospectively or retrospectively recorded data, including the start and finish dates of menstrual cycles, were collected with the app. Detailed data on vaccinations, side effects, and participants' characteristics were retrospectively collected from a questionnaire on the app. For each COVID-19 vaccination shot (first, second, and third), within-individual changes in menstrual cycle length up to the fourth postvaccination cycle were evaluated. RESULTS: Among the 7,376 and 6,873 participants who had the first and second COVID-19 vaccine doses in different menstrual cycles, respectively, menstrual cycles immediately after the vaccination (first postvaccination cycles) were an average of 0.22 days (95% CI, 0.06-0.39) and 0.37 days (95% CI, 0.20-0.54) longer than the prevaccination cycle. In contrast, among the 1,672 participants who received the first and second doses in the same cycle, the first postvaccination cycle was an average of 4.21 days (95% CI, 3.69-4.72) longer. The second to fourth postvaccination cycles returned to the level of the prevaccination cycle. However, among the 4,768 participants who had the third COVID-19 vaccine dose, the menstrual cycle immediately after the vaccination was an average of 1.20 days (95% CI, 1.00-1.40) longer, with prolongation of cycles of 0.27 days (95% CI, 0.10-0.44) to 0.41 days (95% CI, 0.22-0.59) persisting from the second to the fourth postvaccination cycle. CONCLUSION: The booster shot against COVID-19 may have a greater and longer-lasting effect on menstrual cycles than the primary-series shots. Although the effect size was small, evidence on the side effects of immunization on menstruation should be accumulated.

AIM: We aimed to investigate the associations of endometriosis and adenomyosis with pregnancy complications by using a large-scale Japanese database. METHODS: We retrospectively analyzed 145 590 singleton pregnancies from the Japan Perinatal Registry Network Database. Pregnant women registered as having endometriosis or adenomyosis were designated as the case group (EA), whereas the control group (non-EA) was selected using propensity-score matching adjusted for variables such as age, parity, BMI, smoking history, and the use of assisted reproductive technology. The main outcomes included placental malposition, preterm birth, and hypertensive disorders of pregnancy (HDP). RESULTS: In total, 1203 patients from both the EA and non-EA groups were matched and evaluated. The EA group showed significantly higher rates of placenta previa (odds ratio [OR], 3.01; 95% confidence interval [CI], 1.84-4.92), low-lying placenta (OR, 2.02; 95% CI, 1.06-3.86), and preterm birth (OR, 1.44; 95% CI, 1.13-1.84) than the non-EA group. However, no significant difference was observed in the incidence of HDP (OR, 1.22; 95% CI, 0.90-1.66). CONCLUSION: The use of propensity-score matching to analyze a nationwide perinatal database in Japan clarified that EA was associated with increased pregnancy complications, specifically placental malposition, including placenta previa and low-lying placenta, and preterm birth, but not with HDP.

OBJECTIVES: Adenomyosis is associated with unfavorable perinatal outcomes, and recent case reports show that some women with adenomyosis experience pain at the adenomyosis lesion during pregnancy and have detrimental perinatal outcomes. This study aimed to clarify the clinical characteristics of this pain and perinatal outcomes associated with this phenomenon. METHODS: This was a single-center retrospective analysis of pregnant women with adenomyosis. The incidence of pain onset at adenomyosis lesions, defined as persistent pain at the adenomyosis site with administration of analgesics for pain relief, and its association with perinatal outcomes were analyzed. RESULTS: Among 91 singleton pregnancies with adenomyosis, 12 pregnancies (13.2â¯%) presented with pain. One pregnancy resulted in second-trimester miscarriage, and 5 of the 11 pregnancies (45â¯%) developed preeclampsia, which resulted in preterm delivery, and 3 of the 12 pregnancies (25â¯%) achieved term delivery. The incidence of preeclampsia and preterm delivery was higher in those who experienced pain than in those without (45â¯% [5/11] vs. 15â¯% [11/74]; p<0.05, and 73â¯% [8/11] vs. 34â¯% [25/74]; p<0.05, respectively). Among women with pain, the maximum C-reactive protein level was significantly higher in women who developed preeclampsia than in those who did not (5.45 vs. 0.12â¯mg/dL, p<0.05). CONCLUSIONS: Our study revealed that adenomyosis can cause pain in over one of eight pregnancies with adenomyosis, which may be associated with the increased incidence of preeclampsia resulting in preterm delivery. Women with pain, especially those with high C-reactive protein levels, may be at high risk for future development of preeclampsia and consequent preterm delivery.

BACKGROUND: Although abdominal or hysteroscopic metroplasty for septate uterus is considered to reduce pregnancy loss and increase the take-home baby (THB) rate in women with a history of recurrent pregnancy loss, there exists an inherent risk of impaired fertility. This study aimed to clarify the reproductive outcomes of women with septate uterus who underwent abdominal and hysteroscopic metroplasty in a single center. METHODS: This retrospective observational study enrolled 27 women who underwent metroplasty between 2007 and 2019. The analysis included women with septate uterus [European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) type U2)] or septate-bicornuate uterus (ESHRE/ESGE type U3b) who underwent either abdominal or hysteroscopic metroplasty. Women who did not have an immediate desire to conceive were excluded from the analysis. As a rule, we recommended pregnancy without surgery for women who had not experienced repeated pregnancy loss. Abdominal metroplasty (ABM) was performed using the modified Tompkins' method and hysteroscopic metroplasty was performed using hysteroscopic transcervical resection of the septum [transcervical metroplasty (TCM)]. The conception ratio was calculated as the number of women who achieved ≥ 1 conception/total number of women, the pregnancy loss ratio was calculated as the number of women who experienced ≥ 1 pregnancy loss/the number of women who conceived, and the THB ratio was calculated as the number of women who achieved ≥ 1 THB/total number of women. RESULTS: Seventeen women underwent ABM and 10 women underwent TCM. Thirty-three conceptions and 26 babies were taken home after surgery. ABM did not change the ≥ 1 conception ratio (76% vs. 83% before and after surgery, respectively; RR = 1.08, p = 0.80). Meanwhile, ABM decreased the ≥ 1 pregnancy loss ratio (100% vs. 36%, RR = 0.36, p < 0.001) and increased the ≥ 1 THB ratio (12% vs. 71%, RR = 6.00, p < 0.01). Similarly, TCM did not change the ≥ 1 conception ratio, decreased the ≥ 1 pregnancy loss ratio, and increased the ≥ 1 THB ratio. CONCLUSIONS: Both abdominal and hysteroscopic metroplasty for septate uterus increased the THB rate by preventing pregnancy loss without affecting the chance of pregnancy. TRIAL REGISTRATION: Not applicable.
