Multidirectional Traction Method Using SURGICEL NU-KNIT and Surgical Suture in Robot-assisted Laparoscopic Surgery for Endometrial Cancer.

OBJECTIVE: To describe a novel approach to robot-assisted laparoscopic total hysterectomy (RH) for endometrial cancer that minimizes cancer sell spillage and develops a stable surgical field. DESIGN: Demonstration of the multidirectional traction method with narrated video footage. SETTING: Many reports have indicated that RH for endometrial cancer has the same or superior short-term results compared with conventional laparoscopic hysterectomy (LH), and the long-term prognosis is the same [1,2]. However, there are no randomized controlled trials of RH versus LH, and some previous reports [3] have suggested that RH has a worse prognosis than LH, so the long-term prognosis should be considered with caution. Factors that may affect the long-term prognosis include the use of uterine manipulators [4] and compression of the uterine body with robotic forceps without tactile sensation [3]. However, to the best of our knowledge, no surgical technique capable of avoiding these factors has been established yet. Herein, we report a multidirectional traction method using SURGICEL NU-KNIT (Ethicon; Johnson & Johnson Medical Ltd., Tokyo, Japan), a local hemostatic agent, and surgical sutures. INTERVENTION: Cut 2-0 Prolene (Ethicon; Johnson & Johnson Medical Ltd., Tokyo, Japan) with straight needles (ST-70) thread to 35 cm, stick a 1 × 2 cm piece of SURGICEL NU-KNIT, and make knots Fig. 1. This implement is used to puncture the incisional margins of the peritoneum and then the abdominal wall to bring the thread to the surface of the body, where it is grasped with forceps and fixed. By repeating this operation, multidirectional traction can be obtained Fig. 2. A manipulating suture is also attached to the uterus to minimize the compression of the uterine body with robotic forceps. CONCLUSION: The multidirectional traction method allows for reproducible stable surgical field development and minimizes cancer cell spillage by reducing uterine grasping by robotic forceps without the use of uterine manipulators.

Vaginal malignant peripheral nerve sheath tumor treated with complete surgical resection and postoperative radiation therapy.

Malignant peripheral nerve sheath tumors (MPNSTs) are neoplasms originating from or differentiating into nerve sheaths of peripheral nerves. Vaginal origin is rare, with only six vaginal primary cases reported to date. A 55-year-old woman presented to our hospital with a 7 cm vulvar mass. Tumor biopsy results were suspicious of sarcoma, and pelvic magnetic resonance imaging and hysterofiberscopy showed that the tumor originated from the lower vagina. The mass was transvaginally excised, and histological examination confirmed the diagnosis of a vaginal MPNST with negative surgical margins. The patient underwent radiotherapy because the risk of recurrence was high, owing to the large tumor size and high mitotic index. The patient remained recurrence-free for 1 year after the primary treatment. This is the first case of a high-risk vaginal MPNST that avoided early disease recurrence with additional radiotherapy after complete tumor resection.

The impact of assisted reproductive technology on the risk of postpartum hemorrhage: Difference by the mode of delivery and embryo transfer.

AIM: The frequency of postpartum hemorrhage (PPH) is increasing in developed countries, and some reports suggest that assisted reproductive technology (ART) increases various perinatal complications, including PPH. We investigated whether the effect of ART pregnancies on the incidence of PPH is modified by the mode of delivery. METHODS: A retrospective cohort study was performed. We analyzed the medical records of 2914 pregnant women, including 411 pregnancies achieved by ART, which were delivered in our hospital from 2017 to 2020. PPH was defined as hemorrhage exceeding the 90th percentile of blood loss per the mode of delivery and number of fetuses. Multivariable logistic regression analysis was used to assess the association between ART and PPH. Propensity score-matched analyses were used to assess the difference in the incidence of PPH by the mode of delivery. RESULTS: As previously reported, multivariable logistic regression analysis showed that ART pregnancy is an independent risk factor for PPH. Propensity score-matched analysis for with and without ART showed a 3.39-fold higher incidence of PPH for ART pregnancy in the vaginal delivery group (p < 0.001). CONCLUSIONS: The effect of ART pregnancies on the incidence of PPH differed depending on the mode of delivery. Only in vaginal delivery, ART pregnancy increased the incidence of PPH.

Abnormal menstruation after radical trachelectomy and its effects on fertility.

AIM: To evaluate and identify the risk factors for abnormal menstruation after radical trachelectomy. METHODS: This study included 58 patients who underwent radical trachelectomy at our hospital between April 2005 and January 2018. Patients were divided into groups of those with no change in postoperative menstruation (regular [R] group; n = 46) and those with abnormal menstruation such as amenorrhea or hypomenorrhea (irregular [I] group; n = 12). The perioperative characteristics and fertility of the groups were compared retrospectively. The data were statistically analyzed using Student's t-test, Fisher's exact test and Mann-Whitney U test for univariate analysis and logistic regression analysis for multivariate analysis, with the level of statistical significance set at P < 0.05. RESULTS: Based on Federation of Gynecology and Obstetrics staging, 54 patients had stage IB1, 2 had stage IB2 and 2 had stage IIA1 cervical cancer. Eight patients received neoadjuvant chemotherapy. Pretreatment tumor size, residual uterine cavity length and neoadjuvant and postoperative chemotherapy use were not significantly different between the groups. Abnormal menstruation was significantly more common in patients with postoperative pelvic infection (R group, 13.0%; I group, 58.3%) and cervical stenosis (R group, 15.2%; I group, 58.3%). CONCLUSION: To maintain healthy menstruation even after radical trachelectomy, it is important to prevent postoperative pelvic infection and cervical stenosis.

Exploring Attractiveness of the Basic Sciences for Female Physicians.

In Japan, traditional gender roles of women, especially the role of motherhood, may cause early career resignations in female physicians and a shortage of female researchers. Besides this gender issue, a general physician shortage is affecting basic science fields. Our previous study suggested that female physicians could be good candidates for the basic sciences because such work offers good work-life balance. However, the attractiveness for female physicians of working in the basic sciences, including work-life balance, is not known. In a 2012 nationwide cross-sectional questionnaire survey, female physicians holding tenured positions in the basic sciences at Japan's medical schools were asked an open-ended question about positive aspects of basic sciences that clinical medicine lacks, and we analyzed 58 respondents' comments. Qualitative analysis using the Kawakita Jiro method revealed four positive aspects: research attractiveness, priority on research productivity, a healthy work-life balance, and exemption from clinical duties. The most consistent positive aspect was research attractiveness, which was heightened by medical knowledge and clinical experience. The other aspects were double-edged swords; for example, while the priority on research productivity resulted in less gender segregation, it sometimes created tough competition, and while exemption from clinical duties contributed to a healthy work-life balance, it sometimes lowered motivation as a physician and provided unstable income. Overall, if female physicians lack an intrinsic interest in research and seek good work-life balance, they may drop out of research fields. Respecting and cultivating students' research interest is critical to alleviating the physician shortage in the basic sciences.

[A Clinical Comparison of Continuous Sciatic Nerve Block and Epidural Anesthesia for Postoperative Pain Control in Patients with Fracture of the Foot].

BACKGROUND: Epidural analgesia provides good pain relief for patients with fracture of the foot Ultrasound-guided peripheral nerve block offers safety and efficacy without affecting the leg. METHODS: We compared the continuous sciatic nerve block with the continuous epidural anesthesia regarding postoperative pain after the open reduction and internal fixation (ORIF) of the ankle fracture or calcaneal bone fracture. RESULTS: Fifteen patients were included in the epidural group (group E), and 17 patients in the sciatic nerve block group (group S). The postoperative pain scores were significantly lower in group S 3 hours and 12 hours after the procedure, and tended to be lower in other periods. Perioperative periods were uneventful in both groups. CONCLUSIONS: Continuous sciatic nerve block developed good postoperative analgesia in ORIF of ankle fracture or calcaneal bone fracture compared with continuous epidural anesthesia.

Successful fertility preservation in stage II endometrial carcinoma with long-term progestin therapy: A case report.

Progestin therapy is a fertility-sparing treatment option for well-differentiated stage IA endometrioid carcinomas without myometrial invasion. Here, we present a case of successful pregnancy and live birth following long-term progestin therapy in a patient with stage II well-differentiated endometrioid carcinoma. A 30-year-old nulliparous woman with an unremarkable medical history presented with abnormal uterine bleeding. A 45 mm mass was identified in the lower uterine segment. An endometrial biopsy revealed grade 1 endometrioid carcinoma, leading to a diagnosis of stage II uterine corpus cancer based on hysteroscopic findings. The patient refused surgical treatment and underwent oocyte retrieval and cryopreservation at another hospital. A subsequent endometrial biopsy revealed a marked reduction in the Ki-67 index from approximately 60 % to less than 10 %, suggesting the possibility of a hormone-sensitive tumor. The patient persistently refused surgery. Therefore, progestin therapy with medroxyprogesterone acetate (MPA) at a dose of 400 mg/day was initiated as a temporary measure until the patient would accept surgery. The tumor gradually reduced in size and eventually disappeared after 9 months. The MPA therapy was discontinued uneventfully after 20 months. Sixteen months after the discontinuation of MPA therapy, atypical endometrial hyperplasia was detected, and a second round of MPA therapy was initiated. Progestin retreatment was successful and was discontinued at 6 months. Four years after the initial treatment, the patient achieved pregnancy through timed intercourse and delivered a healthy baby at 38 weeks of gestation.

Coexistence of ovarian cancer and peritoneal tuberculosis: a case report.

Peritoneal tuberculosis (TB) is known to mimic advanced ovarian cancer. In this case report, we describe a unique case of ovarian cancer (endometrioid carcinoma grade 3) at the International Federation of Gynecology and Obstetrics (FIGO) stage IC1 with pulmonary and peritoneal TB, which was suspected preoperatively to be a coexistence of advanced ovarian cancer and pulmonary TB. A 68-year-old woman presented with a prominent abdominal mass and fever. Laboratory investigations, imaging, and sputum analysis indicated a probable diagnosis of ovarian cancer at FIGO stage IIIC, characterized by peritoneal dissemination and para-aortic lymph node metastasis, which was further complicated by coexisting pulmonary TB. Surgical management included total abdominal hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy. Intraoperatively, the tumor was localized to the right ovary with significant peritoneal thickening and adhesions indicative of peritoneal TB. The surgery was completed without apparent complications. Postoperative histopathological evaluation confirmed grade 3 endometrioid carcinoma in the right ovary along with evidence of peritoneal TB. Given the extent of adhesions attributed to TB, lymph node dissection for staging was deemed challenging and was thus not pursued. Initiation of anti-TB treatment on postoperative day 2 resulted in marked regression of the preoperatively identified pulmonary nodules and para-aortic lymph node enlargement, suggesting their inflammatory origin from TB. Although postoperative chemotherapy is typically advocated for patients with stage IC1 endometrioid carcinoma grade 3, the patient opted against it. Consequently, no adjuvant therapy was administered and the patient remained under close observation.

Predictive score for postpartum hemorrhage in vaginal deliveries following frozen embryo transfer.

Objective: To develop a predictive score for life-threatening severe postpartum hemorrhage in vaginal deliveries following frozen embryo transfer. Materials and Methods: We conducted a retrospective cohort study of 315 singleton vaginal deliveries following frozen embryo transfer from 2017 to 2022. Severe postpartum hemorrhage was defined as hemorrhage exceeding 1500 mL. A predictive score was generated from maternal characteristics and obstetric complications before delivery. We performed multivariable logistic regression analysis using 2017-2020 data and assigned points to identified risk factors. The predictive score's accuracy was evaluated using 2021-2022 data. Results: A large baby (birth weight ≥3500 g), pre-delivery maternal body mass index ≥25 kg/m2, marginal or velamentous umbilical cord insertion, and history of postpartum hemorrhage were identified as risk factors. We assigned one point to a large baby, a pre-delivery maternal body mass index ≥25 kg/m2, and marginal or velamentous umbilical cord insertion, and two points to a history of postpartum hemorrhage. The sum of the points was defined as the predictive score. The cut-off was set at two points, with a score ≥2 points being the high-risk group and a score ≤1 point being the low-risk group. The predictive score demonstrated a sensitivity of 47.8%, specificity of 85.4%, positive predictive value of 45.8%, and negative predictive value of 86.4% in the 2021-2022 validation cohort. Conclusion: The predictive score identified severe postpartum hemorrhage in approximately half of the high-risk cases. Implementing measures such as autologous blood storage may facilitate rapid response during heavy bleeding and improve maternal prognosis.

Difficulties facing physician mothers in Japan.

Despite recent increases in the number of female physicians graduating in Japan, their premature resignations after childbirth are contributing to the acute shortage of physicians. Previous Japanese studies have explored supportive measures in the workplace, but have rarely focused on the specific problems or concerns of physician-mothers. Therefore, this study explored the challenges facing Japanese physician-mothers in efforts to identify solutions for their retention. Open-ended questionnaires were mailed to 646 alumnae of Juntendo University School of Medicine. We asked subjects to describe their opinions about 'The challenges related to female physicians' resignations'. Comments gathered from alumnae who graduated between 6 and 30 years ago and have children were analyzed qualitatively. Overall, 249 physicians returned the questionnaire (response rate 38.5%), and 73 alumnae with children who graduated in the stated time period provided comments. The challenges facing physician-mothers mainly consisted of factors associated with Japanese society, family responsibilities, and work environment. Japanese society epitomized by traditional gender roles heightened stress related to family responsibilities and promoted gender discrimination at work environment. Additionally, changing Japanese society positively influenced working atmosphere and husband's support. Moreover, the introduction of educational curriculums that alleviated traditional gender role was proposed for pre- and post- medical students. Traditional gender roles encourage discrimination by male physicians or work-family conflicts. The problems facing female physicians involve more than just family responsibilities: diminishing the notion of gender role is key to helping retain them in the workforce.

[Suspected case of peripartum cardiomyopathy during perioperative period--a case report].

A 31-year-old primigravida was admitted for control of twin gestation and delivery. At 36-week gestation, an emergent cesarean section was performed under combined spinal-epidural anesthesia because of progression of PIH. Anesthetic course was uneventful until the operation was finished. An hour later, systolic blood pressure started to decline to reach about 70 mmHg and Sp(O2) about 80%. Pleural effusion was observed in the chest X-ray on post-operative day 1. Echocardiography showed akinesis of the antero-septal wall with ejection fraction (EF) of 47%. Peripartum cardiomyopathy (PPCM) was strongly suspected. HELLP syndrome and DIC were also combined with PPCM, so intensive care was given to her from the 1st POD. Symptoms of heart failure were alleviated by furosemide and carperitide by the 12th POD. The EF increased to 58% on the 11th POD.

A case of laparoscopy-assisted vaginal cuff suturing for vaginal cuff dehiscence after total laparoscopic hysterectomy.

INTRODUCTION: Vaginal cuff dehiscence after hysterectomy is a rare complication and occurs in less than 1% of patients. It can present with serious complications, such as bowel evisceration and peritonitis. PRESENTATION OF CASE: A 51-year-old multigravida Korean woman underwent total laparoscopic hysterectomy for leiomyoma. Six months later, she reported lower abdominal pain and vaginal bleeding. Physical examination revealed rebound tenderness in the lower abdomen, and pelvic examination showed a small amount of vaginal bleeding with an evisceration of the small intestine through the vagina that exhibited healthy peristalsis. The eviscerated bowel, which seemed to be a part of the ileum, was carefully manually reduced transvaginally into the abdominal cavity. Laparoscopic observation revealed adhesions between the omentum, small intestine, and the peritoneum. Specifically, the small intestine was adhered around the vaginal cuff. An abdominal abscess was found in the left lower abdominal cavity. An adhesiotomy was performed and the abdominal abscess was removed and irrigated. Complete separation of the anterior and posterior vaginal cuff edges was obtained. The vaginal cuff was closed with interrupted 0-polydioxanone absorbable sutures without bowel injury. A 6-month follow-up examination revealed complete healing of the vaginal cuff. DISCUSSION: In this case, we were able to make use of both laparoscopic and transvaginal methods to perform a successful repair with a minimally invasive and safe technique. CONCLUSION: Laparoscopically assisted vaginal cuff suturing for vaginal cuff dehiscence after total laparoscopic hysterectomy was found to be effective, safe, and minimally invasive.

Successful delivery after abdominal radical trachelectomy followed by adjuvant chemotherapy for advanced invasive uterine cervical cancer: a case report and literature review.

Uterine cervical cancer is increasingly prevalent among young Japanese women who are eager to preserve their fertility, and abdominal radical trachelectomy (ART) is often performed in patients with early-stage invasive lesions. Herein we present details of a 27-year-old woman with stage IB1 cervical cancer. Although the patient received ART, histopathological findings revealed a parametrial invasion. Hence, 3 courses of adjuvant chemotherapy with paclitaxel and carboplatin (TC) were administered, and the patient conceived spontaneously 44 months later. Rupture of the membrane occurred at 32 weeks and 4 days, and a 1822 g female baby was delivered by emergency cesarean section. The patient is alive without disease and her child is growing favorably. This case demonstrates the balance between preservation of fertility and curative adjuvant chemotherapy after ART.
