RESUMO
BACKGROUND: Gestational diabetes mellitus (GDM) has serious effects on both mother and child. Like Type 2 Diabetes Mellitus, it is increasing in prevalence world-wide. In addition to obesity, sleep duration has been named an important risk factor. Using a large cohort study, including data from 48,787 participants of the Japan Environment and Children's Study (JECS), we examined the association between sleep duration and both random blood glucose levels and GDM rates during pregnancy. METHODS: Random blood glucose levels were measured during pregnancy. GDM diagnosis was based on the results of 75 g oral glucose tolerance test. Additional anthropometric data was collected from questionnaires for statistical analysis. RESULTS: Compared to mothers averaging 7 to < 10 h sleep (reference group), women receiving < 5 h or ≥ 10 h sleep exhibited significantly elevated random blood glucose levels. This was associated with an elevated risk for positive GDM screening (< 5 h sleep: OR 1.17 (0.96-1.44) p = 0.126; ≥10 h sleep: OR 1.13 (1.03-1.25) p = 0.006). Calculating the risk for GDM, women sleeping < 5 h or ≥ 10 h exhibited elevated risks of 1.31-fold and 1.21 respectively. However, this trend was not found to be significant. CONCLUSIONS: Sleep is a critical factor in glucose metabolism, with both abnormally long and short sleep duration increasing random blood glucose levels in pregnant women. Moreover, the risk for positive GDM screening increases significantly with elevated sleep, ≥10 h per night. These findings are promising because they support the idea that sleep duration is a modifiable risk factor, and can be focused upon to improve health and pregnancy outcome.

AIM: Vascular or intestinal injuries at the time of the first trocar insertion can cause serious complications during laparoscopic surgeries. In this study, we evaluate the usefulness of ultrasound scans of the umbilical region as well as intraumbilical conditions to help prevent serious complications. METHODS: The subjects included 430 cases who underwent laparoscopic gynecologic surgeries. The umbilical ultrasound scan was performed after tracheal intubation to observe the intestinal movements associated with respiration. Structures of the umbilical region as well as peristalsis and the movement of the intestinal tract were observed. Then, the thickness of the subcutaneous fat (between the umbilical skin surface and the rectus fascia) and the preperitoneal fat (between the rectus fascia and the peritoneum) were measured. The relationship between body mass index (BMI), insertion time of the first trocar and ultrasound measurements were analyzed. RESULTS: The anatomical structures of the umbilical region (the subcutaneous tissue and the preperitoneal fat) were clearly observed in all cases. The BMI score had a significant relationship with subcutaneous fat thickness (r = 0.547), but remarkably not with preperitoneal fat thickness (r = 0.174). There was no significant relationship between BMI and insertion time. However, insertion time of the first trocar had a significant relationship with preperitoneal fat thickness (r = 0.534). CONCLUSIONS: Preoperative ultrasonography of the umbilical region is asimple process, and it is helpful inpreventing serious complications caused by the first trocar insertion. We have found that preperitoneal fat thickness seems to be an important factor in predicting the potential difficulty of the first trocar insertion.

AIM: To evaluate the perioperative complications and the anatomical outcomes of our laparoscopic uterosacral ligament (USL) colpopexy, which is a novel laparoscopic technique for the management of uterine prolapse. The objective was to report on outcome after 2 years of a technique using laparoscopic USL colpopexy. METHODS: A total of 152 uterine prolapse patients underwent laparoscopic USL colpopexy from May 2013 to April 2015. We described the surgical technique and performed a retrospective analysis of this laparoscopic technique. Patients underwent standardized assessment and examination using pelvic organ prolapse quantification (POP-Q) score. The dependent values of Ba point (bladder), C point (vaginal cuff) and Bp point (rectum) were recorded preoperatively, and at 1, 3, 6, 12 and 24 months of postoperative examination. Pre/postoperative data were compared using the Kaplan-Meier method. RESULTS: Mean age, operative time and amount of hemorrhage were 68.2 ± 7.5 years, 118.3 ± 36.4 min and 60.5 ± 73.3 mL, respectively. Overall recurrent prolapse, which was defined as POP-Q stage II or higher, was noted in 29 patients (19%). However, only 2 patients presented recurrent rectocele among 51 patients with preoperative POP-Q stage II of uterine prolapse alone (recurrence rate; 3.9%). The pre/postoperative average POP-Q scores were -0.2/-2.7 cm (P < 0.05) at Ba point, -1.9/-5.1 cm (P < 0.05) at C point and -2.4/-2.3 cm (P = 0.06) at Bp point. CONCLUSION: Laparoscopic visualization of uterosacral ligaments may result in safe colpopexy. Our results show this will be a useful procedure for apical support as native tissue repair.

The consultation rate for uterine cervical cancer screening in Japan is markedly low in comparison with other developed countries. The purpose of this study is to investigate the trends in uterine cervical cancer screening during regular company checkups and to identify potential problems. Questionnaires were sent to occupational health physicians through Sansuiken (Alumni Association of the University of Occupational and Environmental Health, Japan). Overall, 127 valid responses showed that Papanicolaou (Pap) tests are conducted in 100 companies (79%). The detailed information from 50 of the 100 responses was analyzed. Mandatory cervical cancer screenings are performed at just 6 companies (12%). Pap test are started at 30 years of age at 9 of 49 companies, and only 18 of 49 companies (37%) start Pap tests for employees at 20 years old. Of the 86,695 women, 31,294 (36%) received cervical cancer screening. Abnormal Pap test results were detected in 3.0%. Although cervical cancer screening rates have slightly increased compared to our previous studies (17% in 2004, 23% in 2008), it remains at a low level. Complete examinations with colposcopy and punch biopsy were carried out in 70% (61 of 87 women) of those with an abnormal Pap test. Twelve of 26 companies had no information about detailed examination results. It is important to note that cervical cancer incidence and mortality are increasing among young women in Japan. Occupational physicians and health nurses should manage female health education and care at the workplace, by including uterine cervical cancer screening in the growing female working population.

Fatty metamorphosis is an uncommon alteration in uterine leiomyoma (i.e., lipoleiomyoma), and the pathogenetic mechanisms underlying this phenomenon remain poorly understood. Because a conditional deletion of ß-catenin, a major transducer of the canonical Wingless/integrated (WNT) pathway, in the developing mouse uterus can induce adipogenesis in the myometrium, it is hypothesized that inhibition of the WNT/ß-catenin signaling may be also involved in the development of fat cells within uterine leiomyoma. In the current study, which was performed to address this point, intracytoplasmic lipid droplets were detectable in cultured human leiomyoma cells by treatment with a potent tankyrase inhibitor, XAV939, which antagonizes ß-catenin, in a serum-starved culture medium without additional adipogenesis-inducing agents or supplements, and showed increasing accumulation in a time-dependent manner. In addition, the induction of fat cells was greatly enhanced under hypoxic conditions (i.e., 2.5% O2)-recapitulating the local in vivo situation of uterine leiomyoma-in comparison to that under normoxic conditions (i.e., 21% O2). The marker genes of differentiated fat cells such as ADIPOQ and PLIN were highly expressed in leiomyoma cells that were treated with XAV939 under hypoxia and serum starvation, whereas the immunohistochemical expression of desmin-a cytoskeletal protein representing smooth muscle differentiation-was downregulated, which appears in line with the switch in differentiation. The results of our study suggest that the inhibition of canonical WNT/ß-catenin signaling under the stress due to hypoxia and serum starvation can initiate adipocytic transdifferentiation or metaplasia in human uterine leiomyoma cells, which is potentially related to the development of lipoleiomyoma.

Neonatal sepsis continues to be a global problem with significant morbidity and mortality, because of the difficulty in predicting its onset with clinical symptoms alone. Thus, the presence of biomarkers is useful for the diagnosis of neonatal sepsis. Presepsin is a 13-kDa truncated form of soluble CD14 that is produced through proteolytic cleavage on activated monocytes. Presepsin, consisting of 64 amino acid residues, has been proposed as a reliable biomarker for the early diagnosis of sepsis in neonates. However, some biomarkers for the diagnosis of sepsis are elevated during the early neonatal period due to physiological variation, whereas such variation in presepsin levels is uncertain. The objective of this study is to investigate the physiological variation in plasma presepsin levels during the early neonatal period. This prospective study included 30 full-term healthy neonates, including 15 neonates delivered by cesarean section. Plasma presepsin levels were examined at birth and on the first day and the fifth day of life in neonates, and the levels on the 5th day of life were lower than those at any other points (P < 0.001). Moreover, there was no significant difference of plasma presepsin levels between neonates delivered vaginally and by cesarean section. The physiological variation in plasma presepsin levels was observed during the early neonatal period. Attention needs to be paid when measuring plasma presespsin levels for the screening of sepsis during the early neonatal period.

BACKGROUND: BK-UM (CRM197) is a mutant form of diphtheria toxin and a specific inhibitor of heparin-binding epidermal growth factor-like growth factor (HB-EGF). We assessed the safety, pharmacokinetics, recommended dose, and efficacy of BK-UM in patients with recurrent ovarian cancer (OC) or peritoneal cancer (PC), and measured HB-EGF levels in serum and abdominal fluid after BK-UM administration. METHODS: Eleven patients with advanced or recurrent OC or PC were enrolled and treated with BK-UM via the intraperitoneal route. The dose was escalated (1.0, 2.0, 3.3, and 5.0 mg/m2) using a 3 + 3 design. RESULTS: Eight of 11 patients completed treatment. No dose-limiting toxicity (DLT) was experienced at dose levels 1 (1.0 mg/m2) and 2 (2.0 mg/m2). Grade 3 transient hypotension as an adverse event (defined as a DLT in the present study) was observed in two of four patients at dose level 3 (3.3 mg/m2). Treatment with BK-UM was associated with decreases in HB-EGF levels in serum and abdominal fluid in seven of 11 patients and five of eight patients, respectively. Clinical outcomes included a partial response in one patient, stable disease in five patients, and progressive disease in five patients. CONCLUSIONS: BK-UM was well tolerated at doses of 1.0 and 2.0 mg/m2, with evidence for clinical efficacy in patients with recurrent OC or PC. A dose of 2.0 mg/m2 BK-UM is recommended for subsequent clinical trials. TRIAL REGISTRATION: This trial was prospectively performed as an investigator-initiated clinical trial. The trial numbers are UMIN000001002 and UMIN000001001, with registration dates of 1/30/2008 and 2/4/2008, respectively. UMIN000001001 was registered as a trial for the continuous administration of BK-UM after UMIN000001002 .

INTRODUCTION AND HYPOTHESIS: Transvaginal ipsilateral uterosacral ligament colpopexy for pelvic organ prolapse (POP), which was reported by Shull et al. (Shull's colpopexy) in 2000, is one of the most frequently performed non-mesh pelvic floor reconstructive surgical procedures. Despite its excellent anatomical outcomes, ureteral injury and difficulty in uterosacral ligament detection (especially in patients with severe POP) are typical issues with this procedure. METHOD: This video demonstrates the procedure in a 58-year-old woman, gravida 2 para 2, with POP-Q stage II uterine prolapse and stage I cystocele. At the beginning of the operation, the bilateral uterosacral ligaments were confirmed and separated from the ureters after entering the retroperitoneal space. The inferior hypogastric nerve and pelvic nerve plexus were also separated from the uterosacral ligament. After total laparoscopic hysterectomy, three ipsilateral delayed absorbable monofilament sutures were placed between the uterosacral ligament and the vaginal cuff. Retroperitonealization was then performed using a continuous suture with closure of the Douglas pouch. CONCLUSION: Laparoscopic Shull's colpopexy for POP is a secure procedure with the advantages of laparoscopy (magnification and sharing the operative field). This may become one of the most useful operations for apical support as native tissue repair.

AIM: The purpose of this study is to present alternative diagnostic criteria of colposcopy using new parameters. METHODS: Colposcopic photographs were reviewed in 1649 patients from the past 23 years, including 283 benign lesions, 327 low-grade squamous intraepithelial lesions (LSIL; cervical intraepithelial neoplasia 1), 549 high-grade squamous intraepithelial lesions (HSIL; cervical intraepithelial neoplasia 2/3), 78 microinvasive cancers, and 412 invasive cancers. Abnormal colposcopic findings were divided into: minor or major; single, or a combination of two or three findings; and under half or over half circumferential size. Histopathological backgrounds were investigated according to these new parameters of colposcopic findings. RESULTS: Minor abnormal colposcopic findings were observed in 21% of LSIL, and major abnormal findings were seen in 52% of LSIL, 86% of HSIL, and 86% of microinvasions. A single major abnormal finding was observed in 64% of the cases with LSIL, while two abnormal findings were observed in 43% of HSIL, and three abnormal findings were observed in 44% of microinvasions. In qualifying major abnormal colposcopic findings, under half size was detected in 91% of LSIL and 74% of HSIL, and over half size was observed in 58% of microinvasions. From these results, the following diagnostic criteria were instituted: (i) LSIL - single, minor or major findings and under half size; (ii) HSIL - two or three major findings and under half size; (iii) microinvasion - three major findings and over half size; and (iv) invasive cancer - irregular surface with atypical vessels. CONCLUSION: Our new diagnostic criteria of colposcopy are fully acceptable, based on their similar level of accuracy to cytology.

AIM: Laparoscopic surgery causes fewer postoperative adhesions than laparotomy and adhesion barriers are used to lessen the chance of adhesion. Sodium hyaluronate and carboxymethylcellulose (SH-CMC), a bioresorbable membrane, is effective in preventing adhesions. However, its properties make it difficult to insert the film into the abdominal cavity and to place it into the target area during laparoscopic surgeries. Here we report a novel technique for applying SH-CMC during laparoscopic surgeries by using cut-off surgical glove fingers. METHODS: In our dry-box experiment, we found that SH-CMC became more flexible after moisturizing for 30 s. Therefore, for this procedure, we moisturizing both sides of the SH-CMC sheet (7.35 × 6.35 cm) on wet gauze (for 30 s). The film was rolled into cut-off surgical glove fingers and inserted into the abdominal cavity through a 12-mm trocar. The film was then removed from the glove finger and unrolled onto the target area (glove-finger method). RESULTS: The dry-box experiment revealed that moisturizing both sides of SH-CMC for 30 s/side, 15 min after package removal, made the film more flexible. Ninety of 96 attempts with SH-CMC were successful among the 24 patients who underwent total laparoscopic hysterectomy with our glove-finger method. CONCLUSION: Our glove-finger method can realize the smooth application of SH-CMC to the target area during laparoscopic surgeries.

OBJECTIVES: To analyse the bacterial flora of urine from patients with male urethritis using the clone library method. METHODS: Urine specimens from patients with urethritis were used. The bacterial flora was analysed according to the 16S ribosomal RNA gene-based clone library method. In addition, Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum or Ureaplasma parvum were detected by the conventional PCR methods (TMA or real-time PCR) and data from the clone library and conventional PCR methods were compared. RESULTS: Among 58 urine specimens, 38 were successfully analysed using the clone library method. From the specimens, 2427 clones were evaluated and 95 bacterial phylotypes were detected. N. gonorrhoeae was detected from 6 specimens and as the predominant bacterial species in 5 specimens. M. genitalium was detected from 5 specimens and as the predominant bacterial species in 3 specimens. C. trachomatis was detected from 15 specimens using the TMA method, but was detected from only 1 specimen using the clone library method. U. parvum was detected from only 2 specimens using the clone library method. In addition, Haemophilus influenzae and Neisseria meningitidis were also detected in 8 and 1 specimens, respectively. Gardnerella vaginalis, which is a potential pathogen for bacterial vaginitis in women, was detected in 10 specimens. CONCLUSIONS: The clone library method can detect the occupancy rate of each bacteria species among the bacterial flora and may be a new method for bacterial analyses in male urethritis.

INTRODUCTION AND HYPOTHESIS: The purpose of this paper is to report our evaluation of changes in intravaginal microbial flora after ring pessary therapy for pelvic organ prolapse (POP) using conventional and our clone library method. METHODS: Thirteen patients with POP who were fitted with a ring pessary participated in this longitudinal study that incorporates data from before and 1 month after beginning ring pessary therapy. Changes in intravaginal microbial flora were evaluated by conventional methods, i.e., vaginal pH, lactobacillary grade (LAC grade), Nugent score, and culture-based bacterial detection methods. In addition, we performed our clone library method using 16S ribosomal RNA (rRNA) sequencing of vaginal fluid. RESULTS: Conventional methods revealed that most patients had abnormal intravaginal microbial flora. Mean numbers of detected bacterial species by the culture-based and our clone library method were 3.1 (1-6) and 11.8 (1-25), respectively. Our clone library method showed that Lactobacillus spp. increased in four and decreased in two cases after ring pessary therapy but reappeared after therapy in two cases; no Lactobacillus spp. were detected in five cases. CONCLUSIONS: Our study showed that ring pessary therapy did not always disturb intravaginal microbial flora, especially for patients with Lactobacillus spp. prior to ring pessary insertion. Anaerobic circumstances in the vagina after therapy seem to have induced the growth of anaerobic bacteria.

AIM: Recent developments in transperineal ultrasound imaging of the pelvis have prompted trials to objectively evaluate labor progression for labor management. We evaluated the accuracy of transperineal ultrasound in diagnosing arrest of labor. METHODS: Transperineal ultrasound and digital pelvic examinations were performed simultaneously in 63 term laboring patients (singleton fetuses in cephalic presentation). We analyzed a total of 216 ultrasound images (Sonography Volume Computer Aided Display Labor [Sono VCAD Labor®] installed in Voluson E8 ultrasound). We examined the correlation between the three ultrasound parameters head direction (HD), progression distance (PD), and progression angle (PA), and digital pelvic examination findings during labor in a transvaginal delivery group and an arrested labor group. RESULTS: The coefficient of correlations between HD/PD/PA and cervical dilation/fetal station were 0.667/0.657/0.706 and 0.667/0.751/0.803, respectively. The three parameters had strong correlations with digital pelvic examination (P < 0.05). In the 11 cases (17%) of cesarean section due to arrested labor, the position of the fetal head was visually unchanged on sequential ultrasound images. According to receiver operating characteristic curves, the significant cut-offs for HD, PD, and PA for arrested labor were 105° (P = 0.048), 35 mm (P = 0.048), and 120° (P = 0.001), respectively. CONCLUSIONS: Transperineal ultrasound imaging is helpful for objective evaluation of labor progression and the diagnosis of arrested labor.

Background Several biomarkers for the diagnosis of sepsis are elevated during the early neonatal period due to physiological variations. The aim of this study was to investigate the physiological variation in neutrophil CD64 (nCD64) expression during the early neonatal period and the change in nCD64 expression in neonates with noninfectious diseases. Methods Of 71 neonates enrolled in this prospective study, 5 and 51 were diagnosed as having bacteremia and noninfectious diseases, respectively. Fifteen healthy neonates were enrolled as normal controls. Peripheral white blood cell counts, serum C-reactive protein and procalcitonin levels, and nCD64 expression were examined at birth and on the first and fifth day of life in neonates with noninfectious diseases and healthy neonates. In neonates with bacteremia, these markers were measured at onset. Results nCD64 expression was significantly higher in neonates with bacteremia (median, 1,992) than in those with noninfectious diseases (1,823, p < 0.001) and healthy neonates (1,848, p = 0.002). Unlike other biomarkers, no differences in nCD64 expression were observed on the same days between neonates with noninfectious diseases and healthy neonates. Conclusion nCD64 expression may be a useful marker for the diagnosis of bacterial infection in the early neonatal period, because it does not show any physiological variations.

In this case, a 27-year-old nulliparous woman with a pelvic multiple cystic mass was treated and found with ovarian mature cystic teratoma associated with port-site metastasis (PSM). Suspecting recurrence of mature cystic teratoma, a second laparoscopic surgery found a small mass, on the right under abdomen's peritoneal membrane, at the laparoscopic port sites of the initial operation. Pathological report of the peritoneal mass and left ovarian tumor confirmed a mature cystic teratoma. To the best of the authors' knowledge, this is the first reported PSM in associated with benign ovarian tumor.

Dienogest is a novel progestin with potent oral progestational activity that inhibits the clinical symptoms of endometriosis. We herein evaluated the effect of dienogest on ovarian endometriotic cysts via immunohistochemistry. Ovarian endometriotic cyst specimens were collected from 12 patients treated with dienogest and 20 patients not treated with hormones (controls). The expression of estrogen receptor (ER)-α, progesterone receptor A (PRA), and Ki-67 was studied by immunohistochemistry. As compared with the controls, the cell proliferation index was significantly reduced in both epithelial and stromal cells of the endometriotic cysts following the use of dienogest (P = 0.022 and P = 0.004, respectively). However, there was no significant difference between endometriotic cysts with and without the use of dienogest in the expressions of ER-α and PRA in the epithelial and stromal cells. Irrespective of the use of dienogest, the expression levels of ER-α and PRA in the epithelial cells were low (median: 32% and 8%, respectively). Conversely, the expression levels of ER-α and PRA in the stromal cells were well preserved (median: 68% and 92%, respectively). In the controls, there was no significant difference between endometriotic cysts in the expression levels of Ki-67, ER-α and PRA in epithelial and stromal cells during the proliferative and secretory phases. The finding of a reduction in the cell proliferation index by the use of dienogest with no change in the expressions of hormonal receptors may not support the direct progestational effect of dienogest on ovarian endometriotic cysts.

The SMARCE1 (SWI / SNF-related, matrix-associated, and actin-dependent regulator of chromatin, subfamily e, member 1) encodes BAF57 protein. Previously, we reported that BAF57 is a predictive marker of endometrial carcinoma. In this study, we investigated BAF57 expression in ovarian cancer cell lines and their sensitivities to cisplatin, doxorubicin, paclitaxel, and 5-fluorouracil. BAF57 expression was strongly correlated with sensitivities to cisplatin, doxorubicin, and 5-fluorouracil in 10 ovarian cancer cell lines. Paclitaxel sensitivity was also correlated with BAF57 expression, but without significance. In A2780 ovarian cancer cells, knockdown of BAF57 using specific siRNA increased cell cycle arrest at G1 phase and the sensitivities to these anticancer agents. cDNA microarray analysis of A2780 cells transfected with BAF57 siRNA showed that 134 genes were positively regulated by BAF57, including ATP-binding cassette, sub-family G (WHITE), member 2 (ABCG2) encoding breast cancer resistance protein (BCRP). We confirmed that knockdown of BAF57 decreased BCRP expression in ovarian cancer cells by Western blot analysis, and that ABCG2 gene expression might be regulated transcriptionally. These results suggested that BAF57 is involved in ovarian cancer cell growth and sensitivity to anticancer agents, and that BAF57 may be a target for ovarian cancer therapy.

The second edition of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine cervical cancer was published in 2011. The guidelines comprise eight chapters and five algorithms. They were prepared by consensus among the members of the Japan Society of Gynecologic Oncology Guidelines Formulation Committee and Evaluation Committee and are based on a careful review of the evidence obtained from the literature, health insurance system, and actual clinical settings in Japan. The highlights of the 2011 revision are (1) the recommended grades have been changed to five stages--A, B, C1, C2, and D; (2) the revisions are consistent with the new International Federation of Gynecology and Obstetrics staging system; (3) the roles are shared between the 'Japanese classification of cervical cancer' and the new guidelines; (4) clinical questions related to adenocarcinoma have been revised; and (5) a clinical question regarding cervical cancer in pregnant patients has been added. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. Each recommendation is accompanied by a classification of recommendation categories. The objective of these guidelines is to update the standard treatment strategies for cervical cancer, thus eliminating unnecessary and insufficient treatment.

OBJECTIVE: We investigated the association of positive peritoneal cytology with prognosis in uterine cervical cancer. STUDY DESIGN: We reviewed the medical records and cytologic materials of 225 Japanese patients with FIGO IB1-IVB uterine cervical cancer who had undergone surgery at our University Hospital between 1993 and 2012. Univariate and multivariate regression analyses were performed for statistical analysis. RESULTS: Positive peritoneal cytology was noted in 6 of 225 patients (2.7%). Positive peritoneal cytology was found in 4 of 149 patients (2.6%) with squamous cell carcinoma (SCC) and in 2 of 70 patients (2.8%) with non-SCC (p = 0.9434). The 5-year survival rate of patients with positive peritoneal cytology was significantly lower than that of patients with negative cytology (50 vs. 84.6%, p = 0.001) in univariate survival analysis. However, peritoneal cytology no longer remained significant in multivariate analysis. CONCLUSION: Although we conclude that positive peritoneal cytology in uterine cervical cancer is a poor prognostic factor, further investigation and multi-institutional studies are necessary.

A 31-year-old nulligravid woman with a 3 year history of infertility visited our hospital. After consultation and a transvaginal ultrasound and MR imaging, her uterine anomaly was identified as complete septate uterus: class V (a) by the American Fertility Society (AFS). She had a doubled uterine cervix and a vaginal septum. Hysteroscopic metroplasty was performed with the aid of a laparoscopy. Both tubal patencies were confirmed with indigocarmine in a laparoscopic image. Laparoscopic electronic cautery was also done on the left ovarian endometrioma (stage 1 endometriosis; the revised American Society for Reproductive Medicine (rASRM) classification 4 point minimal). We distrained an intrauterine device in the uterine cavity and removed it after two cycles of menstruation. The patient subsequently became pregnant during her third menstrual cycle and the current progress of her pregnancy is favorable.
