		                        			Transmasculine individuals, considering whether to undergo total hysterectomy with bilateral salpingectomy, have the option to have a concomitant oophorectomy. While studies have evaluated hormone changes following testosterone therapy initiation, most of those patients have not undergone oophorectomy. Data are currently limited to support health outcomes regarding the decision to retain or remove the ovaries. We performed a retrospective chart review of transmasculine patients maintained on high-dose testosterone therapy at a single endocrine clinic in Vancouver, British Columbia, Canada. Twelve transmasculine individuals who underwent bilateral oophorectomy and had presurgical and postsurgical serum data were included. We identified 12 transmasculine subjects as controls, who were on testosterone therapy and did not undergo oophorectomy, but additionally matched to the first group by age, testosterone dosing regimen, and body mass index. There was a statistically significant decrease in the estradiol levels of case subjects postoophorectomy, when compared to presurgical estradiol levels (P = 0.02). There was no significant difference between baseline estradiol levels between control and case subjects; however, the difference in estradiol levels at follow-up measurements was significant (P = 0.03). Total testosterone levels did not differ between control and case subjects at baseline and follow-up (both P > 0.05). Our results demonstrate that oophorectomy further attenuates estradiol levels below what is achieved by high-dose exogenous testosterone alone. Correlated clinical outcomes, such as impacts on bone health, were not available. The clinical implications of oophorectomy versus ovarian retention on endocrinological and overall health outcomes are currently limited.

		                        			Objective: To compare the prognosis and perioperative situation of patients with stage Ⅱ endometrial cancer (EC) between radical hysterectomy/modified radical hysterectomy (RH/mRH) and simple hysterectomy (SH). Methods: A total of 47 patients diagnosed EC with stage Ⅱ [International Federation of Gynecology and Obstetrics (FIGO) 2009] by postoperative pathology, from January 2006 to January 2021 in Peking University People's Hospital, were analyzed retrospectively. The patients were (54.4±10.7) years old, and the median follow-up time was 65 months (ranged 9-138 months). They were divided into RH/mRH group (n=14) and SH group (n=33) according to the scope of operation. Then the prognosis of patients between the groups were compared, and the independent prognostic factors of stage Ⅱ EC were explored. Results: (1) The proportions of patients with hypertension in RH/mRH group and SH group were 2/14 and 45% (15/33), the amounts of intraoperative blood loss were (702±392) and (438±298) ml, and the incidence of postoperative complications were 7/14 and 15% (5/33), respectively. There were significant differences (all P<0.05). (2) The median follow-up time of RH/mRH group and SH group were 72 vs 62 months, respectively (P=0.515). According to Kaplan-Meier analysis and log-rank method, the results showed that there were no significant difference in 5-year progression-free survival (PFS) rate (94.3% vs 84.0%; P=0.501), and 5-year overall survival rate (92.3% vs 92.9%; P=0.957) between the two groups. Cox survival analysis indicated that age, pathological type, serum cancer antigen 125 (CA125), and estrogen receptor (ER) status were associated with 5-year PFS rate (all P<0.05). But the scope of hysterectomy (RH/mRH and SH) did not affect the 5-year PFS rate of stage Ⅱ EC patients (P=0.508). And level of serum CA125 and ER status were independent prognostic factors for 5-year PFS rate (all P<0.05). Conclusions: This study could not find any survival benefit from RH/mRH for stage Ⅱ EC, but increases the incidence of postoperative complications. Therefore, the necessity of extending the scope of hysterectomy is questionable.

		                        			BACKGROUND:
		                        			Massive bleeding is the main concern for the management of placenta percreta (PP). Intra-abdominal aortic balloon occlusion (IABO) is one method for pelvic devascularization, but the efficacy of IABO is uncertain. This study aims to investigate the outcomes of IABO in PP patients.
		                        		
		                        			METHODS:
		                        			We retrospectively reviewed the clinical data of PP cases from six tertiary centers in China between January 2011 and December 2015. PP cases with/without the use of IABO were analyzed. Propensity score matching analysis was performed to reduce the effect of selection bias. Postpartum hemorrhage (PPH) and the rate of hysterectomy, as well as neonatal outcomes, were analyzed.
		                        		
		                        			RESULTS:
		                        			One hundred and thirty-two matched pairs of patients were included in the final analysis. Compared with the control group, maternal outcomes, including PPH (68.9% vs. 87.9%, χ2 = 13.984, P < 0.001), hysterectomy (8.3% vs. 65.2%, χ2 = 91.672, P < 0.001), and repeated surgery (1.5% vs. 12.1%, χ2 = 11.686, P = 0.001) were significantly reduced in the IABO group. For neonatal outcomes, Apgar scores at 1 minute (8.67 ± 1.79 vs. 8.53 ± 1.68, t = -0.638, P = 0.947) and 5 minutes (9.43 ± 1.55 vs. 9.53 ± 1.26, t = 0.566, P = 0.293) were not significantly different between the two groups.
		                        		
		                        			CONCLUSIONS
		                        			IABO can significantly reduce blood loss, hysterectomies, and repeated surgeries. This procedure has not shown harmful effects on neonatal outcomes.

		                        			OBJECTIVE: This study is to compare the baseline characteristics and symptoms between groups with leiomyoma only (group M; myoma group), adenomyosis only (group A; adenomyosis group), and leiomyoma and adenomyosis together (group B; group for both disease). METHODS: Selected patients were who received total abdominal hysterectomy, laparoscopy-assisted vaginal hysterectomy, or total laparoscopic hysterectomy from January 2014 to December 2015, and whose pathology result showed leiomyoma (n=74), adenomyosis (n=27), or both (n=63). Baseline characteristics and symptoms were reviewed from the medical records. Researched characteristics included patients' age, degeneration of leiomyoma, endometrial hyperplasia, endometriosis, weight of the removed uterus, menopause before the surgery, method of the surgery, necessity for blood transfusion before and after the surgery, difference of hemoglobin level before and after the surgery, and number of gravida, para, and abortion. RESULTS: Eleven symptoms were checked. Thirty-eight point four percent of total subject had uterine leiomyoma and adenomyosis at the same time. Number of abortion was higher in the group B. The group B showed a tendency of presenting more menorrhagia, dysfunctional uterine bleeding, acute lower abdominal pain, and urinary frequency. Symptoms related to mass effect seem to be relative to uterine leiomyoma, and symptoms related to menorrhagia seems to be relative to adenomyosis. The group M showed suddenly growing mass symptoms, and was more likely to have massive hemorrhage during the surgery. It is hard to differentiate coexistence of uterine leiomyoma and adenomyosis from each disease. CONCLUSION: Coexistence of two disease exhibits mixed symptoms of each disease, but shows different tendency.

		                        			OBJECTIVE: The present study aimed to determine the differences in outcomes between natural orifice transluminal endoscopic surgery-assisted vaginal hysterectomy (NAVH) and conventional laparoscopy-assisted vaginal hysterectomy (LAVH). METHODS: We retrospectively reviewed the charts of patients who between July 2012 and September 2015, were diagnosed as having benign uterine disease such as uterine myoma, endometriosis, or adenomyosis and managed via NAVH or LAVH in a single-center (Eulji University Hospital). Data such as age, body weight, height, parity, operation time, intra/post-operative complications, and uterus weight were obtained from the clinical charts. NAVH and LAVH recipients were matched 1:3 in terms of baseline characteristics, and the 2 groups were compared regarding surgical outcomes. RESULTS: Of the 160 patients with benign uterine disease included in the present study. Forty received NAVH and remaining 120 received LAVH. There were significant differences between the groups regarding operation time and hemoglobin change. Notably, although the operation time was shorter for LAVH, hemoglobin change was lower for NAVH. Additionally, although maximum hospitalization duration was shorter for LAVH, the average length of hospitalization was similar between NAVH and LAVH. There were no significant differences between the groups in terms of other variables. CONCLUSION: NAVH may become a new alternative surgical method of choice for hysterectomy, as it represents a clinically feasible and safe approach; moreover is superior to LAVH in terms of bleeding loss.

		                        			OBJECTIVE: The aim of this study was to compare and determine the feasibility, surgical outcomes, learning curves of robotic radical hysterectomy with lymph node dissection (RRHND) to conventional laparoscopic radical hysterectomy with lymph node dissection (LRHND) performed by a single surgeon, in patients with cervical cancer. METHODS: Between April 2009 and March 2013, 22 patients underwent LRHND and 19 patients underwent RRHND. Variables such as age, body mass index, International Federation of Gynecology and Obstetrics stage, histological results, number of dissected lymph nodes, operative time, estimated blood loss, days of hospitalization and complications were reviewed. Learning curves of operation time was obtained using cumulative sum (CUSUM) method. RESULTS: Both groups showed similar patient and tumor characteristics. In surgical outcome analysis, RRHND (51.8±10.4 minutes) showed longer preparing time than LRHND (42.5±14.1 minutes). In the LRHND group, 8 patients experienced postoperative complications (5 void difficulty, 1 postoperative bleeding, 1 right basal ganglia infarction, 1 fever). On the other hand, in the RRHND group, 4 patients experienced a postoperative complication (2 bleeding, 1 peritonitis, 1 dehiscence of trocar site). Using CUSUM method, the learning curves were obtained by plotting the cumulative sequential differences between each data point and the average operation time, and showed two distinct phases in both type of operations. CONCLUSION: RRHND would be appropriate surgical approach in patients with cervical cancer with favorable outcome of less voiding difficulty. A minimum of 13 cases of robotic radical hysterectomies are required to achieve surgical improvement in the treatment of cervical cancer.

		                        			OBJECTIVES: To identify factors responsible for potentially clinically unnecessary cervical cancer screenings in women with prior hysterectomy. METHODS: A retrospective cross-sectional study was conducted using the Centers for Disease Control and Prevention’s Behavioral Risk Factor Surveillance System (BRFSS). This study targeted adult women and examined whether they received a both a Papanicolaou (Pap) test and undergone a hysterectomy in the last three years. We conducted multivariate analyses, including weighted proportions and odds ratios (ORs), based on the modified BRFSS weighting method (raking). The inclusion criteria were adult women (>18 years old) who reported having received a Pap test within the last 3 years. RESULTS: Of all women (n=252 391), 72 366 had received a Pap test, and 32 935 of those women (45%, or 12.5 million, weighted) had a prior hysterectomy. We found that age, race/ethnicity, marital status, family income, health status, time since last routine checkup, and health insurance coverage were all significant predictors. Black, non-Hispanic women were 2.23 times more likely to receive Pap testing after a hysterectomy than white women (OR, 2.23; 95% confidence interval [CI], 1.99 to 2.50). Similarly, the odds for Hispanic women were 2.34 times higher (OR, 2.34; 95% CI, 1.97 to 2.80). The odds were also higher for those who were married (OR, 1.17; 95% CI, 1.08 to 1.27), healthier (OR, 1.24; 95% CI, 1.14 to 1.35), and had health insurance (OR, 1.54; 95% CI, 1.28 to 1.84), after controlling for confounders. CONCLUSIONS: We conclude that women may potentially receive Pap tests even if they are not at risk for cervical cancer, and may not be adequately informed about the need for screenings. We recommend strategies to disseminate recommendations and information to patients, their families, and care providers.

		                        			OBJECTIVE: This study was conducted using the human papillomavirus (HPV) DNA chip test (HDC), in order to determine whether the HPV genotype is a predictor of residual disease in a subsequent hysterectomy following a loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 3. METHODS: Between January 2002 and February 2015, a total of 189 patients who underwent a hysterectomy within 6 months of LEEP caused by CIN 3 were included in this study. We analyzed their epidemiological data, pathological parameters, high-risk HPV (HR-HPV) load as measured by the hybrid capture II assay, and HR-HPV genotype as measured by the HDC. A logistic regression model was used to analyze the relationship between covariates and the probability of residual disease in subsequent hysterectomy specimens. RESULTS: Of the 189 patients, 92 (48.7%) had residual disease in the hysterectomy specimen, CIN 2 in seven patients, CIN 3 in 79 patients, IA1 cancer in five patients, and IA2 cancer in one patient. Using multivariate analysis, the results were as follows: cone margin positivity (odds ratio [OR], 2.43; 95% CI, 1.18 to 5.29; p<0.05), HPV viral load > or =220 relative light unit (OR, 2.98; 95% CI, 1.38 to 6.43; p<0.01), positive endocervical cytology (OR, 8.97; 95% CI, 3.81 to 21.13; p<0.001), and HPV-16 or HPV-18 positivity (OR, 9.07; 95% CI, 3.86 to 21.30; p<0.001). CONCLUSION: The HPV-16 or HPV-18 genotype is a reliable predictive factor of residual disease in a subsequent hysterectomy following a LEEP for CIN 3.

		                        			Endometrial hyperplasia (EH) comprises a spectrum of changes in the endometrium ranging from a slightly disordered pattern that exaggerates the alterations seen in the late proliferative phase of the menstrual cycle to irregular, hyperchromatic lesions that are similar to endometrioid adenocarcinoma. Generally, EH is caused by continuous exposure of estrogen unopposed by progesterone, polycystic ovary syndrome, tamoxifen, or hormone replacement therapy. Since it can progress, or often occur coincidentally with endometrial carcinoma, EH is of clinical importance, and the reversion of hyperplasia to normal endometrium represents the key conservative treatment for prevention of the development of adenocarcinoma. Presently, cyclic progestin or hysterectomy constitutes the major treatment option for EH without or with atypia, respectively. However, clinical trials of hormonal therapies and definitive standard treatments remain to be established for the management of EH. Moreover, therapeutic options for EH patients who wish to preserve fertility are challenging and require nonsurgical management. Therefore, future studies should focus on evaluation of new treatment strategies and novel compounds that could simultaneously target pathways involved in the pathogenesis of estradiol-induced EH. Novel therapeutic agents precisely targeting the inhibition of estrogen receptor, growth factor receptors, and signal transduction pathways are likely to constitute an optimal approach for treatment of EH.
