RESUMO
Objective: In several randomized controlled trials (RCTs), sacrospinous hysteropexy and other forms of hysteropreservation have been compared. Nevertheless, there is no definitively best treatment. This study summarized RCT evidence for various uterine preservation surgical procedures. Methods: From each database inception to August 2023, we searched PubMed, Embase, Cochrane Library, and Web of Science for eligible RCTs. A comparison was made between sacrospinous hysteropexy and other hysteropreservation, including vaginal and abdominal surgery. For categorical and continuous variables, relative risks (RRs) and mean differences (MDs) were calculated using random-effects models. Results: We reviewed a total 1,398 studies and ultimately included five RCTs that met all inclusion criteria. These five studies included a total of 1,372 uterine POP cases all of whom received transvaginal surgery and had a follow-up period for assessment of recurrence from 12 months to 5 years. There were no significant differences between sacrospinous hysteropexy and other hysteropreservation for the incidences of recurrence (RR,1.24; 95% CI, 0.58 to 2.63; p = 0.58) or hematoma (RR,0.70; 95% CI, 0.17 to 2.92; p = 0.62). Moreover, neither sacrospinous hysteropexy nor hysteropreservation had any significant effect on the risk of mesh exposure (RR,0.34; 95% CI, 0.03 to 4.31; p = 0.41), dyspareunia (RR,0.45; 95% CI, 0.13 to1.6; p = 0.22), urinary tract infection (RR,0.66; 95% CI, 0.38 to 1.15; p = 0.15), bothersome bulge symptoms (RR,0.03; 95% CI, -0.02 to 0.08; p = 0.24), operative time (MD, -4.53; 95% CI, -12.08 to 3.01; p = 0.24), and blood loss (MD, -25.69; 95% CI, -62.28 to 10.91; p = 0.17). However, sacrospinous hysteropexy was associated with a lower probability of pain (RR,4.8; 95% CI, 0.79 to 29.26; p = 0.09) compared with other hysteropreservation. Conclusion: There was no difference between sacrospinous hysteropexy and hysteropreservation in terms of recurrence, hematoma, mesh exposure, dyspareunia, urinary tract infection, bothersome bulge symptoms, operative time, pain, and blood loss.

RESUMO
BACKGROUND: Transvaginal Natural Orifice Transluminal Endoscopy (vNOTES) is regarded as a challenging surgical technique to learn but is promising in reducing perioperative pain and significantly improves the cosmetic outcomes. Previous studies on the learning curve analysis of vNOTES mainly focuses on the hysterectomy approach, while the vNOTES ovarian cystectomy's learning curve was merely reported though more frequently performed than vNOTES hysterectomy. Therefore, this study seeks to analyze the learning curve of three surgeons with varying levels of experience in performing endoscopic surgery and vaginal surgeries for the treatment of ovarian cysts using vNOTES. METHODS: A total of 127 patients with ovarian cysts of a variety of pathological types were treated by ovarian vNOTES performed by three surgeons of different levels of endoscopic and transvaginal surgical experience. Each surgeon's learning curve was plotted using the Cumulative Sum method and divided into three or four phases of technique learning at the turning point of the learning curve. The sociodemographic and clinical features of patients in each phase were then compared and factors potentially associated with operation time were also screened. RESULTS: The learning curve was presented in four phases. The operation time (OT) was significantly shorter in phases II (53.66 ± 16.55 min) and IV (54.39 ± 23.45 min) as compared with phases I (68.74 ± 15.85) and III (75.93 ± 30.55) (p < 0.001). More cases of serve pelvic adhesion and endometrioma were assigned in the later phases. The OT of endometriotic cysts had much longer than that of non-endometriotic cysts(62.57 ± 18.64 min vs. 49.88 ± 14.26 min, p = 0.15) The presence of pelvic adhesion [adjusted odds ratio (OR) 7.149 (0.506, 13.792), p = 0.035] and bilateral cyst [adjusted OR 16.996 (2.155, 31.837), p = 0.025], max diameter of cyst[adjusted OR 2.799 (0.174, 5.425), p = 0.037], and individual surgeon [adjusted OR -6.118 (-11.814, -0.423), p = 0.035] were significantly associated with OT. CONCLUSION: There learning curve of ovarian vNOTES has four phases. ovarian vNOTES could be mastered after performing seven, nine, and 16 cases by surgeons #1, 2 and 3 respectively, in gynecologic endoscopic surgeries.

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) is an achievement in the field of minimally invasive surgery. However, the vantage point of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecologicalprocedures remains unclear. The main purpose of this study was to compare vNOTES with laparo-endoscopic single-site surgery, and to determine which procedure is more suitable for ambulatory surgery in gynecologic procedures. METHODS: This retrospective observational study was conducted at the Department of Gynecology, Chengdu Women's and Children's Central Hospital. The 207 enrolled patients had accepted vNOTES and laparo-endoscopic single-site surgery in gynecology procedures from February 2021 to March 2022. Surgically relevant information regarding patients who underwent ambulatory surgery was collected, and 64 females underwent vNOTES. RESULTS: Multiple outcomes were analyzed in 207 patients. The Wilcoxon Rank-Sum test showed that there were statistically significant differences between the vNOTES and laparo-endoscopic single-site surgery groups in terms of postoperative pain score (0 vs. 1 scores, p = 0.026), duration of anesthesia (90 vs. 101 min, p = 0.025), surgery time (65 vs. 80 min, p = 0.015), estimated blood loss (20 vs. 40 mL, p < 0.001), and intestinal exhaustion time (12.20 vs. 17.14 h, p < 0.001). Treatment with vNOTES resulted in convenience, both with respect to time savings and hemorrhage volume in surgery and with respect to the quality of the prognosis. CONCLUSION: These comprehensive data reveal the capacity of vNOTES to increase surgical efficiency. vNOTES in gynecological procedures may demonstrate sufficient feasibility and provide a new medical strategy compared with laparo-endoscopic single-site surgery for ambulatory surgery in gynecological procedures.

Objective: This study aimed to assess the surgical outcomes and identify the conversion risk factors of Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in treating ovarian cyst. Methods: This was a retrospective study of 505 patients who underwent vNO TES for treating ovarian cyst from March 2019 to February 2022 wherein the patients were classified into "converted" or "nonconverted" groups. T-tests, χ2 tests, and logistic regression were used for statistical analyses. Results: There were 16 (3.17 %) surgical conversions and 12 (2.38 %) other surgical complications in our study cohort. Teratomas accounted for 56.8 % of complications in nonconverted cases and 18.8 % in converted cases. Adenocystomas were found in 12.3 % of nonconverted cases and 18.8 % of converted cases. Other types included paraovarian cysts (3.3 % and 0 %), fibroma, granulosa cell tumor, Brenner tumor (1.2 % and 0 %), corpus luteum cysts, follicular cysts (7.6 % and 6.3 %), old abscess (0.2 % and 0 %), and simple cysts (17.6 % and 12.5 %) in the nonconverted and converted groups, respectively. The converted group included more cases of endometriotic cysts (43.8 % vs 12.3 %, p = 0.023), bilateral cysts (37.5 % vs 8.2 %, p < 0.001), severe pelvic adhesion (68.8 % vs 3.3 %, p < 0.001), deep endometriosis (12.5 % vs 0.4 %, p < 0.001), and at least two cysts (37.5 % vs 8.81 %; p < 0.001). Severe pelvic adhesion (adjusted odds ratio [OR], 86.96; range, 18.33-431.77; p < 0.001), bilateral cysts (adjusted OR, 4.75; range, 1.05-21.57, p = 0.043) and endometriotic cysts (adjusted OR, 7.69; range, 3.11-17.08; p < 0.001) were also predictors of surgical conversion. Conclusion: vNOTES demonstrates low complication and conversion rates in treating ovarian cyst compared with TU-LESS. Surgical conversion is associated with severe pelvic adhesions, bilateral cysts, and endometriotic cysts.
RESUMO
OBJECTIVE: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is considered to have the advantages of completely scarless, less postoperative pain, earlier flatus, and faster postoperative recovery. However, posterior myoma are relatively difficult to operate through vNOTES in the conventional lithotomy position. Thus, we innovated the application of prone position in the removal of posterior myoma in vNOTES. The aim of this study is the comparison of myomectomy outcomes of patient for single posterior myoma in prone and lithotomy position. DESIGN: A single-center, prospective study. SETTING: A university teaching hospital. PATIENTS: A total of 81 patients with posterior myoma who underwent myomectomy in vNOTES from January 2021 to December 2022. INTERVENTIONS: The patients underwent myomectomy in vNOTES in prone or lithotomy position. MEASUREMENTS AND MAIN RESULTS: Among the patients who underwent vNOTES myomectomy, 29 (35.8%) were in the lithotomy position group, and 52 (64.2%) in the prone position group. Of note, 4 (4.9%) patients underwent a conversion to LESS during the operation-3 in the lithotomy and 1 in the prone position group. And a patient in the lithotomy position group underwent resurgery for hemostasis due to postoperative pelvic bleeding. Compared with the lithotomy position, prone position significantly shortens the operation time (12.3, 95% CI: 6.811, 17.761. p = .009) without increasing the complications and postoperative discomfort of patients. CONCLUSION: Compared to the lithotomy position, the prone position provides greater convenience for operation and exhibits a lower rate of surgical conversion during the removal of single posterior myomas via vNOTES. Further, for patients selecting vNOTES, surgeons need to conduct sufficient preoperative evaluation, timely hemostasis during surgery, and timely surgical conversion if necessary to ensure patient safety.
RESUMO
Background: Poly (ADP-ribose) polymerase (PARP) inhibitor and antiangiogenic agent monotherapy have shown to be effective as maintenance treatment in patients with ovarian cancer (OC). However, there is currently a lack of evidence-based study to directly compare the effects of combination therapy with these two drugs. Therefore, this study aimed to compare the efficacy and safety of combination therapy with PARP inhibitors and antiangiogenic agents in women with OC using a meta-analysis. Methods: An exhaustive search of literature was undertaken using multiple databases, including PubMed, Web of Science, Embase, and the Cochrane Library to identify pertinent randomized controlled trials (RCTs) published up until 17 December 2023. The data on progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were pooled. We computed the pooled hazard ratios (HRs) and their 95% confidence intervals (CIs) for PFS and OS, along with the relative risks (RRs) and 95% CIs for AEs. Trial sequential analysis, heterogeneity test, sensitivity analysis, and publication bias assessment were performed. Stata 12.0 and Software R 4.3.1 were utilized for all analyses. Results: This meta-analysis included 7 RCTs with a total of 3,388 participants. The overall analysis revealed that combination therapy of PARP inhibitors and antiangiogenic agents significantly improved PFS (HR = 0.615, 95% CI = 0.517-0.731; 95% PI = 0.379-0.999), but also increased the risk of AEs, including urinary tract infection (RR = 1.500, 95% CI = 1.114-2.021; 95% PI = 0.218-10.346), fatigue (RR = 1.264, 95% CI = 1.141-1.400; 95% PI = 1.012-1.552), headache (RR = 1.868, 95% CI = 1.036-3.369; 95% PI = 0.154-22.642), anorexia (RR = 1.718, 95% CI = 1.320-2.235; 95% PI = 0.050-65.480), and hypertension (RR = 5.009, 95% CI = 1.103-22.744; 95% PI = 0.016-1580.021) compared with PARP inhibitor or antiangiogenic agent monotherapy. Our study has not yet confirmed the benefit of combination therapy on OS in OC patients (HR = 0.885, 95% CI = 0.737-1.063). Additionally, subgroup analyses further showed that combination therapy resulted in an increased risk of AEs, encompassing thrombocytopenia, vomiting, abdominal pain, proteinuria, fatigue, headache, anorexia, and hypertension (all p < 0.05). Conclusion: Our study demonstrated the PFS benefit of combination therapy with PARP inhibitors and antiangiogenic agents in patients with OC. The OS result need to be updated after the original trial data is mature. Clinicians should be vigilant of AEs when administering the combination therapy in clinical practice.

RESUMO
The aim of the case control study was to compare surgical outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy with the da Vinci surgical system (dVSS) and conventional vNOTES. A case control study was performed on 25 cases in our hospital. Patients (nâ =â 8) who underwent vNOTES hysterectomy with dVSS were selected to compare with the control group (nâ =â 17) consisted of patients who underwent conventional vNOTES. Patients in the 2 groups underwent different operations respectively, and no case was transferred to transabdominal laparoscopy. In the conventional vNOTES group, 1 patient happened intraoperative hemorrhage of about 1000 mL, and was treated with blood transfusion, and the other one of vNOTES hysterectomy with dVSS had poor incision healing within 1 month after surgery. The other patients had no intraoperative and postoperative complications. The difference of pain scores on the first day (Pâ =â .006) and the third day (Pâ =â .045) after the 2 surgical methods differed significantly. No statistical differences were observed in operation time, median hospital stay, blood loss, decreased hemoglobin 3 days after surgery, and postoperative white blood cell count. vNOTES hysterectomy with dVSS is safe and feasible, and can achieve the same effect as the conventional vNOTES hysterectomy. And this method may alleviate the pain of patients.

In this report, we described a new technique of gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices in a porcine model. As a result, the gynecological procedures were successfully completed. The total operative time was 110 min, while the docking time was 10 min. The estimated blood loss was estimated to be 10 mL with no intraoperative complications. It revealed that gasless V-NOTES for hysterectomy and salpingectomy on a robotic platform with flexible devices appeared to be feasible and safe in the porcine model and has the potential for clinical use in human beings.

We conducted a randomized controlled trial to assess the feasibility and safety of performing gynecological single-port transumbilical laparoscopic-assisted adnexal surgery without urethral catheterization in a day surgery setting. A total of 153 patients with adnexal disease were enrolled in this prospective randomized controlled trial (RCT). All subjects performed single-port transumbilical laparoscopic-assisted adnexal surgery between March 2021 and July 2022 in a day surgery center. After completion of the baseline survey, participants were randomized into one of three groups. Participants were randomized into one of three groups: uncatheterized (n = 51), intermittent catheterized (n = 51), or indwelling catheterized (n = 51). The primary outcomes were the incidence of lower urinary tract symptoms (LUTS) and microscopic hematuria, and the secondary outcomes included the incidence of urinary tract infection (UTI), the incidence of urinary retention, the incidence of bladder injury, the time till first urination, the time till first ambulation, the time till first exhaust, the time till first feeding and Kolcaba comfort score. The incidence of postoperative LUTS in the uncatheterized group (17.65%) was lower than that in the intermittent catheterized group (52.94%) and the indwelling catheterized group (84.31%), and there was significant difference between the two catheterized groups (P < 0.001). In the patients without vaginal manipulation, the incidence of microscopic hematuria in the uncatheterized group (0%) was lower than that in the intermittent catheterized group (37.50%) and the indwelling catheterized group (38.89%) (P < 0.05). There were no significant differences in the first urination time, first ambulation time, first exhaust time, first feeding time, and comfort score among the three groups (P > 0.05). Moreover, no urinary retention, UTI and bladder injury were recorded in the three groups. Gynecological single-port laparoscopic adnexal surgery without urinary catheter is safe and feasible in a day surgery ward, which can reduce the incidence of postoperative LUTS and microscopic hematuria.
RESUMO
Objective: We aimed to determine the safety of Vaginal natural orifice transluminal endoscopic surgery (vNOTES) in terms of the Enhanced Recovery after Surgery (ERAS) concept for tubal pregnancy surgery and provide a detailed process of vNOTES for tubal pregnancy surgery, including experience and key points for surgeons performing this procedure. Methods: The Longitudinal Vaginal Natural Orifice Transluminal Endoscopic Surgery Study (LovNOTESS), which was conducted in Chengdu, China. A total of 219 patients who underwent tubal ectopic pregnancy surgery between September 2021 and March 2022. The patients underwent salpingectomy or salpingostomy using transumbilical laparoendoscopic single-site surgery (LESS) or vNOTES, according to their preferences. This study prospectively collected perioperative and one-year follow-up data on tubal pregnancy outcomes after vNOTES and compared them with those after LESS. Results: The vNOTES group showed a shorter surgical duration, hospitalization duration, and postoperative exhaust time and a lower analgesic medication usage rate, but it showed a higher surgical conversion rate. The vNOTES approach reduced the postoperative exhaust time by approximately 9 h (95% confidence interval [CI]: -11.93, -5.57 h, p < .001) and the risk of postoperative analgesic drug use by 77% (odds ratio, 0.23; 95% CI: 0.10, 0.61, p = .023). Conclusion: vNOTES can shorten the exhaust time and duration of hospitalization, reduce postoperative pain, and avoid surface surgical scars in tubal pregnancy surgeries, consistent with the ERAS concept. However, more comprehensive preoperative evaluation of patients who choose vNOTES is required to reduce the occurrence of intraoperative conversion.Trial registration: ChiCTR2100053483.
RESUMO
Introduction: Recurrent reproductive failure (RRF) is a common pregnancy complication, imposing great physical, emotional and financial burden for the suffered couples. The leading cause of RRF is believed to be aneuploid embryo, which could be solved by preimplantation genetic testing for aneuploidy (PGT-A) in theory. With molecular genetic development, PGT-A based on comprehensive chromosomal screening (CCS) procedures and blastocyst biopsy is widely applied in clinical practice. However, its effects in RRF were not defined yet. Methods: A systematic bibliographical search was conducted without temporal limits up to June, 2023. Studies about the effects of PGT-A based on CCS procedures and blastocyst biopsy in RRF were included. Results: Twenty studies about the effects of PGT-A based on CCS procedures and blastocyst biopsy in RRF were included. It revealed that PGT-A could optimise the reproductive outcomes of RRF sufferers, especially in those with advanced age. However, in patients with multiple occurrences of pregnancy losses, the benefits of PGT-A were limited. Discussion: More randomized controlled trials with large sample size are required to evaluate the benefits of PGT-A in RRF sufferers and identify which population would benefit the most.
RESUMO
OBJECTIVE: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is widely recognized for its potential benefits, including reducing post-surgical pain and leaving no discernible scarring. However, the anatomical specificity of the vNOTES approach may elevate the risk of nearby organ damage, such as the rectum and bladder. Thus, this study aims to demonstrate the safety and relative merits of vNOTES over transumbilical laparoendoscopic single-site surgery (LESS). METHODS: The Longitudinal Vaginal Natural Orifice Transluminal Endoscopic Surgery Study (LovNOTESS), which was conducted in Chengdu, China. A total of 110 patients who underwent myomectomy in vNOTES or LESS from January 2021 to December 2022. This study prospectively collected and compared perioperative and follow-up data of the two groups. RESULTS: In the vNOTES group, patients had shorter postoperative anal exhaust time, lower pain medications use rate, shorter hospital stay but higher intraoperative conversion rate, and higher postoperative fever rate. vNOTES decreased the anal exhaust time by approximately 8.7 h (95 %CI: -16.182, -1.262, p = 0.007). Moreover, vNOTES reduces pain medication use risk by 73.1 % (OR: 0.269, 95 %CI: 0.172, 0.318, p = 0.016). CONCLUSION: Relative to LESS, vNOTES can make patients mitigate postoperative discomfort, accelerate the recovery of gastrointestinal function, curtail hospitalization duration, and enable a more rapid return to daily activities in myomectomy. However, vNOTES has a higher risk of surgical conversion and adjacent organ injury. Therefore, larger scale prospective studies are needed to prove its security and promote the widespread application of vNOTES in myomectomy.

Background: To describe the surgical technique and operative outcomes of transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) for sacrocolpopexy with or without robotic surgical system in patients with pelvic organ prolapse (POP). Methods: Patients with POP undergoing traditional transvaginal natural orifice transluminal endoscopic surgery (TV-NOTES) or robotic transvaginal natural orifice transluminal endoscopic surgery (RV-NOTES) for sacrocolpopexy performed by one surgeon from Sep 2020 to Jan 2023 in our hospital were included in this study. The baseline demographics and operative outcomes were collected and analyzed. In addition, some surgical skills were presented. The operative outcomes of V-NOTES for sacrocolpopexy performed by three beginners were also presented. Results: Eight patients who underwent TV-NOTES, and two patients who underwent RV-NOTES were included in this study. The mean operative time was 180 ± 49 min, and the estimated blood loss was 107 ± 82 ml for these ten cases. Particularly, the operative time of the two patients who underwent RV-NOTES was 275 and 132 min, while the estimated blood loss (EBL) was 100 and 50 ml respectively. During the follow-up period, no mesh exposure and recurrence were observed. In addition, five cases of TV-NOTES for sacrocolpopexy by beginners were all successfully completed. Conclusion: Both TV-NOTES and RV-NOTES appeared to be feasible and safe for sacrocolpopexy.
RESUMO
OBJECTIVE: To reflect on the complications of transvaginal natural orifice transluminal endoscopic surgery (vNOTES), identify the corresponding risk factors, and provide caution to surgeons when performing this novel surgery. METHODS: A retrospective study was carried out among 2000 patients in our hospital who underwent vNOTES between May 2019 and May 2022. Perioperative complications were stratified in chronological order and divided into those developed while establishing the vNOTES approach, during surgery, postoperatively, and 1 month after discharge. The complications were classified based on the Modified Clavien-Dindo classifications. The causes of each type III/IV complication were analyzed. RESULTS: Of the 2000 patients, 88 (4.4%) experienced complications, which is not higher than that reported in laparoendoscopic surgery in previous studies. Grade I, II, III, IV, and V complications developed in 19 (0.95%), 57 (2.85%), 11 (0.55%), 1 (0.05%), and 0 (0%) patients, respectively. Complications were developed while establishing the approach platform, during the surgery, postoperatively, and within 1 month after discharge in 5 (0.25%), 30 (1.50%), 50 (2.50%), and 3 (0.15%) patients, respectively. Eight patients (0.4%) underwent conversion, including five cases of rectal injury repair. CONCLUSION: The summarized suggestions were divided into three levels. Considering the security and effectiveness of vNOTES, it can be routinely used in various gynecologic operations. However, surgeons should focus on preoperative evaluation, strictly conduct preoperative disinfection, conform to prompt conversion during surgery, call for the presence of experienced doctors, and have routine use of antibiotics to prevent postoperative infections.

BACKGROUND: This study aimed to assess the predictive value of endometrial blood flow branches on pregnancy outcomes after hormone replacement therapy-frozen embryo transfer (HRT-FET). METHODS: This prospective observational study involved 292 reproductive-aged women who underwent endometrial receptivity assessment in a tertiary care academic medical center in southwest China using power Doppler ultrasonography during HRT-FET. Three-dimensional power Doppler ultrasound was performed on the day of endometrial transformation and the day before embryo transfer. The endometrial blood flow branches of the endometrial and subendometrial regions were compared in the non-pregnant and pregnant groups at the two time points mentioned above. RESULTS: The endometrial blood flow branches were higher in pregnant patients than in non-pregnant patients on the day of endometrial transformation (P = 0.009) and the day before embryo transfer (P = 0.001). Changes in endometrial blood flow pattern and endometrial blood flow branches at the two time points did not differ among the pregnancy outcome samples. After adjusting for age, antral follicles, and embryos transferred, the endometrial blood flow branches on the day before embryo transfer was the independent factor influencing the chance of clinical pregnancy, with an odds ratio of 3.001 (95% confidence interval: 1.448 - 6.219, P = 0.003). CONCLUSIONS: Endometrial blood flow perfusion during the peri-transplantation period of the HRT-FET cycle is a good indicator of pregnancy outcomes, suggesting that valuation of endometrial branches via power Doppler ultrasound is a simple and effective approach for achieving indicator measurements.

BACKGROUND: Literature regarding the advantages of gasless vNOTES is insufficient. The aim of our study is to compare gasless vNOTES vs. traditional vNOTES on hemodynamic profiles and outcomes in patients with benign gynecological disease. We hypothesize that compared with those in the traditional vNOTES group, hemodynamic profiles will be changed less during gasless vNOTES, while safety can be promised. METHODS: This is a single-center, prospective, single-blind, randomized controlled clinical trial, which has been approved by the Institutional Review Board of Chengdu Women's and Children's Hospital on September 27, 2022. One hundred and twenty patients will be recruited and randomly assigned to either the traditional vNOTES group or the gasless vNOTES group in a 1:1 ratio. For patients allocated to the traditional vNOTES group, after insertion of one port through the vagina, CO2 gas is infused with a pressure of 12-14 mmHg; while for those allocated to the gasless vNOTES group, a special device is used as an abdominal wall-lifting device to facilitate gasless surgery. CO2 pneumoperitoneum will not be used during the whole gasless vNOTES procedure. The primary outcome is vital signs at different time points. The secondary outcomes include surgical conversion rate, duration of surgery and anesthesia, anesthetic consumption, intraoperative estimated blood loss, VAS and PONV scores at postoperative 2 h and 24 h, administration of vasopressor drugs from the beginning of general anesthesia induction to 15 min after endotracheal intubation, including times, dosage, and type, intraoperative and postoperative complications, time of first getting out of bed after surgery, and time of first eating after surgery, including light drink. DISCUSSION: This is the first randomized controlled trial to compare the impacts of gasless vNOTES vs. traditional vNOTES on hemodynamic profiles and outcomes in patients with benign gynecological disease. If a favorable effect and safety of gasless vNOTES for hemodynamic profiles and outcomes in patients are shown, gasless vNOTES would be an optimal treatment option for patients with benign gynecological disease.

BACKGROUND: To evaluate the effect of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) on female sexual function. METHODS: The trial was registered at the Chinese Clinical Trial Registry (ChiCTR2100050887, 07/09/2021). In this prospective cohort study, we prospectively analyzed the data of the female sexual function index (FSFI) questionnaire of 130 patients who underwent laparoscopy in Chengdu Women's and Children's Central Hospital due to gynecological benign diseases. The patients were assigned to the vNOTES group and the control group (underwent traditional laparoscopic surgery or transumbilical laparoendoscopic single-site surgery). RESULTS: There were 4 cases dropout in the vNOTES group and 2 cases dropout in the control group. There was no difference in the ages (31.70 ± 5.02 vs. 30.37 ± 5.74, P>0.05), BMI (body mass index, 21.76 ± 3.16 vs. 23.30 ± 2.69, P>0.05), Education level, surgical types, and FSFI scores (22.31 ± 2.25 vs. 21.55 ± 3.38) between the vNOTES group and the control group before surgery. There was no difference in FSFI scores six months postoperation between the vNOTES group and the control group (21.61 ± 3.22 vs. 20.99 ± 3.26, P>0.05), and there was no difference in FSFI scores pre- and six months postoperation in vNOTES group (21.61 ± 3.22 vs. 22.31 ± 2.25, P>0.05). The time to start sexual life after surgery in the vNOTES group was later than that in the control group (39.34 ± 0.71 d versus 37.86 ± 0.69 d, P < 0.05). CONCLUSIONS: vNOTES has no significant adverse effect on female sexual function, however, the time to start sexual life after vNOTES is later than that after trans-abdominal laparoscopy.

Objective: This study aimed to identify the risk factors for subchorionic hematoma (SCH) in the first trimester of in vitro fertilization (IVF) twin pregnancies and investigate the impact of SCH on pregnancy outcomes. Study design: A prospective cohort study was conducted at Chengdu Women and Children's Central Hospital. The study recruited patients who were identified with twin pregnancies in the first trimester, undergoing IVF treatment from January 2020 to May 2021. The demographic characteristics and pregnancy outcomes were compared between the SCH and the non-SCH groups. A logistic regression analysis was used to determine the risk factors for SCH and adverse pregnancy outcomes. Results: In the first trimester, 38% of patients developed SCH. The independent risk factors for SCH included male factor, hydrosalpinx, polycystic ovary syndrome (PCOS), previous miscarriage, and adenomyosis. With respect to the pregnancy outcomes, only the rate of twin pregnancy loss before 20 gestational weeks was significantly higher in the SCH group than in the non-SCH group. After adjusting for the confounding factors, the presence of SCH diminished the ovarian reserve, and previous miscarriage was independently related to twin pregnancy loss before 20 gestational weeks. Conclusion: This may be the first study to evaluate the risk factors of SCH in twin pregnancies who underwent IVF-ET/FET treatment, which may provide some theoretical basis for clinical practice in the future. Furthermore, it was found that the occurrence of SCH was associated with the loss of both pregnancies before 20 gestational weeks. Therefore, these patients should be offered increased surveillance and timely treatment.
RESUMO
Introduction: Although previous studies have shown that vaginal natural orifice transluminal endoscopic surgery (vNOTES) has the advantages of causing less pain, faster recovery, and better concealment of surgical incisions, which aligns with the concept of the day-care procedure, this approach poses a greater risk of damaging adjacent organs (i. e., rectum and bladder) due to its anatomical specificity. Moreover, the day-care procedure may lead to relatively less preoperative evaluation and postoperative care. Hence, it is necessary to explore the safety and effectiveness of vNOTES for ovarian cystectomy in the day-care procedure, to provide a theoretical basis for the wider development of vNOTES surgery. Materials and methods: This retrospective study included 131 patients at our hospital who underwent ovarian cystectomy from September 2021 to October 2022. Based on the surgical approach, patients were classified into transumbilical laparoendoscopic single-site surgery (LESS) and vNOTES groups. The patients' demographic characteristics and follow-up data were collected during the perioperative period and 1-month postoperatively. Results: Vaginal natural orifice transluminal endoscopic surgery has less postoperative exhaust time, a lower postoperative 6-hour pain score, and a lower incidence of analgesic drug use, with higher surgical conversion incidence. Multiple linear regression analysis showed that the surgical conversion, chocolate cyst, bilateral cyst, and pelvic adhesion increased the operation duration by ~43 (95% CI: 10.309, 68.152, p < 0.001), 15 (95% CI: 6.342, 45.961, p = 0.036), 10 (95% CI: 3.07, 40.166, p = 0.019), and 8 (95% CI: 4.555, 26.779, p = 0.035) min, respectively. Interestingly, vNOTES decreased the operation duration by ~8.5 min (95% CI: -18.313, -2.699, p = 0.033). Conclusion: Vaginal natural orifice transluminal endoscopic surgery was equally safe and effective for ovarian cystectomy compared to LESS. vNOTES aligned with the concept of the day-care procedure due to its reduced postoperative pain, shorter exhaust time, and absence of scarring. However, surgeons should conduct a comprehensive preoperative evaluation and exclude patients suspected to have severe pelvic adhesions.
RESUMO
Objective: The goal of this research was to investigate the feasibility, safety, and short-term clinical outcome of pure extraperitoneal sacrocolpopexy with transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) for treating central pelvic defects. Material and Methods: A total of 9 patients with central pelvic prolapse underwent extraperitoneal sacrocolpopexy with V-NOTES, at the Chengdu Women's and Children's Central Hospital, Chengdu, Sichuan, China, between December 2020 and June 2022. The patients' demographic characteristics, perioperative parameters, and clinical outcomes were analyzed retrospectively. Each patient had the following major surgical procedures: (1) Establishing a platform for an extraperitoneal approach with V-NOTES; (2) separating the extraperitoneal path to the sacral promontory region; (3) suturing the long arm of the mesh to the anterior longitudinal ligament S1; and (4) suturing and fixating the short arm of the mesh at the top of the vagina. Results: The median patient age was 55, the median operative time was 145 minutes, and the median intraoperative blood loss was 150 mL. The operations were successful for all 9 cases, with a median preoperative Pelvic Organ Prolapse-Quantification score of C: +4, and a 3-months postoperative score of C: -6. There were no recurrences during a follow-up of 3-11 months, and no complications occurred, such as mesh erosion, exposure, and infection. Conclusion: As a new surgical approach, extraperitoneal sacrocolpopexy with V-NOTES is safe and feasible. (J GYNECOL SURG 39:108).
