BACKGROUND: There is a growing body of evidence indicating that second-degree tears cause both short- and long-term consequences. Very few preventative measures have been found to reduce the incidence of these tears. OBJECTIVE: This study aimed to investigate whether the use of a perineal protection device during vaginal birth reduces severe perineal tearing (grade >= 2 tear) in primiparous women compared with routine manual perineal support. STUDY DESIGN: A single-center randomized controlled trial was conducted in Sweden from 2019 to 2021. Primiparous women at term were randomly allocated to the intervention group (n=43), where a perineal protection device was used, or to the routine care group (n=49). The primary outcome was grade of perineal tear. The secondary outcomes were vaginal and labial tearing. Continuous data were analyzed using the Student test or Mann-Whitney U test. Dichotomous data were analyzed using the Pearson X2 2 test, Fisher exact test, and ordinal logistic regression. RESULTS: Women in the intervention group had a significantly lower risk of sustaining more extensive perineal tearing than those in the control group. The use of the perineal protection device decreased the of grade >= 2 tears in relation to grade 0 to 1 tears (odds ratio, 0.40; 95% confidence interval, 0.17-0.94). Ordinal logistic regression analyses revealed an odds ratio of 0.36 (95% confidence interval, 0.16 -0.81) per incremetn of grade injury using the perineal protection device vs routine care (P=.013). The number needed to treat using perineal protection device was 4.3 to avoid 1 grade >= 2 tear. Women the treatment group showed less labial tearing (P=.016). No adverse effect was detected. CONCLUSION: The use of a perineal protection device reduced risk of grade >= 2 perineal tearing by 60% and labial tearing.

Background:The introduction of vaginal natural orifice transluminal endoscopic surgery (vNOTES) to the toolbox of gynecologic surgeons has the potential to reverse the trend of vaginal hysterectomy declines.Methods:This review discusses nuances of the vNOTES technique applied to hysterectomy; describes vNOTES hysterectomy, step-by-step (including tips and tricks for low- and high-complexity cases for surgeons who may want to incorporate vNOTES hysterectomy into their surgical repertoires); and examines evidence and research trends in this field.Results:The descriptions in the text, figures, tables, and videos all contribute to giving readers a clear understanding of vNOTES, its advantages, limitations, and research potentials.Conclusions:vNOTES hysterectomy is a unique blend of vaginal, laparoscopic, and laparoendoscopic single-site surgery (LESS) techniques and is not a new procedure, but rather another tool to use in minimally invasive gynecologic surgery.

OBJECTIVE:To present the rates of intra- and postoperative complications and conversions in a large cohort of unselected vNOTES hysterectomies, performed by surgeons with different levels of expertise. DESIGN:International register-based cohort study. SETTING:Hysterectomies in the iNOTESs registry, 2015 to January 2024, performed by 201 surgeons from multiple countries. POPULATION:4565 patients undergoing vNOTES hysterectomy. METHODS:Descriptive data are presented in frequencies (n) and percent (%). MAIN OUTCOME MEASURE:Intra- and postoperative complications. Conversions. RESULTS:Intraoperative and postoperative complication rates were 3.2% (n = 144) and 2.5% (n = 115), respectively. Conversions occurred in 1.6% (n = 72), of which 10 (0.2%) to laparotomy, and 82% of the conversions occurred within the first 50 cases of the surgeon's learning curve. The most common intraoperative complication was cystotomy, occurring in 1.3%, and almost half were performed by inexperienced surgeons. Other intraoperative organ injuries occurred in 20 cases (0.44%). Postoperatively, the most common complications were haemorrhage (n = 28), vault complications (n = 26) including 11 infected vault hematomas, cystitis (n = 18) and non-specific infections (n = 14). The vNOTES hysterectomies were performed by 201 surgeons, of which 9.5% had performed more than 50 vNOTES cases, representing 70% of the registered cases in the registry. The remaining 30% of the hysterectomies mainly represent learning curve data from 90% of the included surgeons. The complication rate decreased with increasing surgical experience. CONCLUSIONS:The largest study population of vNOTES hysterectomies is presented, including both learning curve data and data from experienced surgeons, with acceptable rates of intra- and postoperative complications. No implication was found of vNOTES being inferior to other minimally invasive methods.

INTRODUCTION:No national recommendation for antibiotic prophylaxis for planned caesarean section in Sweden exists. Swedish delivery units have chosen different strategies. Some units routinely administer antibiotic prophylaxis to all women for whom a caesarean section is planned, while other units give prophylactic antibiotics to risk groups only. We took advantage of this "natural experiment" to compare the risk of antibiotic prescription postpartum after planned caesarean section, by antibiotic prophylaxis strategy. MATERIALS AND METHODS:An observational study based on data from Swedish registers. The population is based on women giving birth by planned caesarean section from 37 + 0 weeks of gestation, 2014-2020 (n = 7308). The risk of antibiotic prescription postpartum was compared between women who delivered in hospitals with a general routine of administrating antibiotics (n = 5637) for planned CS and women who delivered in hospitals administrating prophylaxis in conjunction with planned caesarean section to risk groups only (n = 1671). Adjusted incidence rate ratios (AIRR) were obtained using modified Poisson-regression models, adjusting for maternal age, parity, and body mass index. MAIN OUTCOME MEASURES:Antibiotic postpartum was defined as a prescription of antibiotics postpartum 2-42 days after planned caesarean section. RESULTS:No difference in antibiotic prescription postpartum among women in hospitals with a general routine of prophylaxis, compared to women in hospitals with a risk-based strategy was found, RR: 1.18 (95 % CI 0.99-1.40). Women with identified risk factors (diabetes/gestational diabetes and/or BMI > 30), were more likely 1.52 (95 % CI 1.03-2.25) to receive a prescription postpartum in hospitals with a general routine of antibiotic prophylaxis than women delivered at hospitals with risk-based strategy. CONCLUSIONS:We found no evidence that routinely administrated prophylactic antibiotics for women with planned caesarean section reduced the risk of a prescription of postpartum antibiotics in a setting with high hygiene standards. Instead, the incidence of prophylactic antibiotics was positively associated with postpartum antibiotic prescriptions and speculate that this reflects local practice routines rather than complication rates.

The technique to perform adnexectomy for adnexal masses has shifted over the last decades, from open surgery towards minimally invasive approaches. At the same time caution is warranted to prevent perioperative intra-abdominal spilling of cyst content which can be a challenge especially for very large masses. vNOTES (vaginal Natural Orifice Transluminal Endoscopic Surgery) combines a vaginal approach with endoscopic overview in performing gynaecological surgery without abdominal scarring. The aim of the video is to demonstrate a vNOTES technique for safely bagging very large adnexal masses.

Objective: To describe a retroperitoneal transient occlusion of the uterine or internal iliac artery in conjunction with a high-risk evacuation of products of conception. The procedure was performed vaginally, minimally invasively, via vaginal natural ori fi ce transluminal endoscopic surgery. Design: Description of the surgical technique using original video footage. This study was exempted from requiring hospital institutional review board approval. Setting: Teaching hospital. Patient(s): A 34-year-old woman (G8P3) with a medical history of 2 cesarean sections, 1 partial mole, and a missed abortion with 2.8 L of blood loss. The patient presented after 10 weeks of amenorrhea. Ultrasound revealed a large blood- fi lled niche in the cesarean section scar with a thin overlying myometrium. A partial mole was suspected as well as increased vascularization in the myometrium and enhanced myometrial vascularity with arterial fl ow velocities of 100 cm/s. A risk of heavy blood loss in conjunction with curettage was anticipated. The patient had a strong preference for a fertility-preserving treatment, and after informed consent, she opted for transient occlusion of the uterine arteries with subsequent suction evacuation of the molar pregnancy. The patient signed a consent form accepting the procedure. The patient included in this video provided consent for publication of the video and posting of the video online including social media, the journal website, and scienti fi c literature websites. Institutional review board approval was not required in accordance with the IDEAL guidelines. Intervention(s): A vaginal incision was made over the bladder, and the vaginal mucosa was dissected. The paravesical space was dissected over the arcus tendinous, and the pelvic retroperitoneal space was opened. A small (7 cm) GelPOINT V-Path (Applied Medical, Rancho Santa Margarita, California) was inserted into the obturator fossa and insuf fl ated with 10 CO 2 mm Hg. Standard laparoscopic instruments were used through the gel port. Under endoscopic view, dissection to the right obturator fossa and iliac vessels was made, and the internal iliac artery was identi fi ed. A removable clip was placed on the origin of the right uterine artery. The same procedure was performed on the left side where the internal iliac artery was clipped. Different vessels were clipped to demonstrate and investigate the feasibility of both approaches. Both vessels were equally accessible. Care should be taken not to injure the uterine vein at the time of clipping. Dilation and evacuation was performed under transanal ultrasound surveillance. When hemostatic control was assured, fi rst, the right clip was removed from the iliac artery. Hemostatic control was ensured, and after 10 minutes, the second clip on the left iliac artery was removed. The GelPOINT was removed, and the vaginal incision was sutured. The patient bled in total 500 mL. Main Outcome Measure(s): Not applicable. Result(s): The patient recovered swiftly without complications. Pathology con fi rmed a partial molar pregnancy. Conclusion(s): Uterine or internal iliac artery ligation can be lifesaving in situations with massive bleeding from the uterus. Current minimally invasive approaches are laparoscopic vessel ligation and, more commonly, uterine artery embolization, which has unclear impact on fertility and has shown an increased risk of intrauterine growth restriction, miscarriage, and prematurity. As the patient was undergoing a vaginal evacuation of pregnancy, a vaginal and retroperitoneal approach of artery ligation was deemed least invasive. In patients with fertility -preserving wishes, care should to be taken to avoid as much trauma as possible to the endometrium. Optimized blood control, and a shorter duration of using a curette, may potentially reduce the risk of endometrial damage. We present a novel minimally invasive approach via vaginal natural ori fi ce transluminal endoscopic surgery - retroperitoneal transient occlusion of the internal iliac or uterine artery. The whole procedure can be performed by the operating gynecologist, and the occlusion is transient and can be reversed in a stepwise controlled manner. (Fertil Steril (R) 2024;121:703-5.

Urinary incontinence affects 25-45 % of women with the gold standard surgical approach being placement of mid-urethral synthetic slings; tension-free vaginal tape (TVT) and trans-obturator tape (TOT). Due to the controversies regarding vaginal mesh the last decade, an increasing demand has evolved for incontinence treatment without vaginal synthetic mesh. The short term results of autologous rectus fascia sling for TOT surgery have shown similar success rates compared to those after the use of synthetic mesh, but the harvesting of the mesh is less minimally invasive and is associated with longer surgical time. vNOTES is a combination of a vaginal entrance to the abdomen and endoscopy via the vagina. The aim with the video is to show a new surgical technique with a fully vaginal, scarless vNOTES approach for harvesting the posterior rectus fascia for TVT and TOT procedures.

OBJECTIVE:Vaginal hysterectomy combined with uterosacral suspension (USLS) is a technique for treating pelvic organ prolapse. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) has been described as an alternative minimal invasive approachfor treating various gynecological and non-gynecological pathologies. The aim was to compare the surgical time between conventional vaginal hysterectomy combined with USLS and vNOTES hysterectomy combined with USLS. STUDY DESIGN:Multi-center randomized controlled trial performed 2019-2021 at Rambam Health Care Campus (Israel) and Imelda Hospital (Belgium). Thirty women underwent vNOTES procedures and 30 women underwent conventional vaginal procedures. The primary outcome was total surgical time. Secondary outcomes included hysterectomy time, USLS time, intraoperative bleeding, length of hospitalization, pain during the first 24 h postoperative, the need of analgesia, intraoperative and postoperative adverse events, and patient-reported outcomes questionnaires. Parametric statistical methods were used to analyze the data. RESULTS:Compared to conventional vaginal procedures, vNOTES procedures were shorter in total surgical time (77 vs. 93 min, p = 0.004), hysterectomy time (26 vs 33 min, p < 0.001), and USLS time (20 vs 26 min. p = 0.02). Blood loss was higher in conventional vaginal compared to vNOTES surgery, as reflected by the mean blood loss estimate (143 vs 60 ml. p < 0.001) and the delta-hemoglobin (pre-operation minus the post-operation hemoglobin level (1.8 vs 1.2 ml/dL, p = 0.01). There was no difference between the groups regarding analgesics used, postoperative pain, surgical objective outcomes, and scores on patient-reported outcomes questionnaires. Adverse events were significantly more frequent in the conventional vaginal group than in the vNOTES group (p < 0.001 for intraoperative events and p = 0.05 for events that occurred in the follow-up time interval). CONCLUSION:vNOTES hysterectomy with USLS has lower surgical times than conventional vaginal hysterectomy with USLS, lower blood loss and less adverse events. Other surgical objective and subjective outcomes were similar between the approaches.

Introduction Hysterectomy is one of the most common surgeries performed in women. Minimally invasive methods are on the rise globally as they have been shown to decrease surgical morbidity compared with abdominal hysterectomy. Hysterectomy by vaginal natural orifice transluminal endoscopic surgery (vNOTES) is the latest innovation. It combines the vaginal approach and endoscopy via the vagina. Large pragmatic randomised controlled trials (RCTs) are lacking comparing outcomes after vNOTES, vaginal hysterectomy (VH) and laparoscopic hysterectomy (LH).Methods Multicentre pragmatic RCT aiming to recruit 1000 women aged 18–75 years undergoing hysterectomy for benign disease. The RCT includes two identical substudies (groups A and B). If VH is considered safe and feasible, the patient will be randomised within group A (VH vs vNOTES). If VH is not considered safe or feasible, patients will be randomised within group B (LH vs vNOTES).Analysis Primary outcome is the proportion of women leaving the hospital within 12 hours after surgery. Secondary outcomes are hospitalisation time, conversion rates, duration of the surgical procedure, intraoperative complications, postoperative complications and readmission.Ethics and dissemination The Ethical Board Committee at Imelda Hospital, Bonheiden, Belgium, has approved the research protocol 230704 (principal investigator). Before including patients, all centres will require local or national ethical approval. The results of the study will be published in international peer-reviewed journals.Trial registration number NCT05971875.

No consensus exists whether to administer prophylactic antibiotics in conjunction with manual placenta removal. This study aimed to investigate the postpartum risk of a new prescription of antibiotic treatment, a possible indirect variable for infection, after manual placenta removal. Obstetric data were merged with data from the Anti-Infection Tool (Swedish antibiotic registry). All vaginal deliveries (n = 13 877) at Helsingborg Hospital, Helsingborg, Sweden, from January 1st, 2014 until June 13th, 2019 were included. Diagnosis codes for infection can be lacking, while the Anti-Infection Tool is complete as it is unavoidable in the computerized prescription system. Logistic regression analyses were performed. The risk of a prescription of antibiotics 24 h to 7 days postpartum was analyzed in the entire study population, and in a subgroup of women not having received any antibiotics 48 h prior to delivery until 24 h after delivery, referred to as “antibiotic-naïve.” Manual placenta removal was associated with an increased risk of an antibiotic prescription, adjusted (a) OR = 2.9 (95

ObjectiveObstetric anal sphincter injuries (OASIS) are severe complications to vaginal births with potential long-term consequences. Maternal origin has been proposed to affect the overall risk, but the association and underlying explanation are uncertain. The objective was to assess the association between maternal country of birth and OASIS.MethodsA Swedish nationwide cohort study including singleton term vaginal births during 2005-2016. Data were extracted from the Swedish Medical Birth Registry and Statistics Sweden. Modified Poisson regression analyses were performed to obtain crude and adjusted risk ratios (RRs). Adjustments were made in four cumulative steps. Sub-analyses were performed to investigate the risk of OASIS associated with female genital circumcision (FGC).ResultsIn all, 988 804 births were included. The rate of OASIS in Swedish-born women was 3.5%. Women from East/Southeast Asia had an increased risk of OASIS (adjusted RR [aRR] 1.71, 95% confidence interval [CI] 1.60-1.83), as did women born in Sub-Saharan Africa (aRR 1.60, 95% CI 1.49-1.72). The risk remained significantly increased also after adjustment for maternal height. By contrast, women from South/Central America had a decreased risk of OASIS (aRR 0.65, 95% CI 0.56-0.76). FGC was associated with an increased risk of OASIS (aRR 3.05, 95% CI 2.60-3.58). Episiotomy appeared to have an overall protective effect (aRR 0.95, 95% CI 0.92-0.98), but not significantly more protective among women with female genital mutilation.ConclusionsCountry of birth plays an important role in the risk of OASIS. Women from East/Southeast Asia and Sub-Saharan Africa are at significantly increased risk as compared with Swedish-born women, whereas women from South/Central America are at lower risk. FGC is also a significant risk factor for OASIS. Maternal country of birth plays an important role in the risk of sphincter injuries. Female genital circumcision is associated with increased risk of sphincter injuries.

INTRODUCTION AND HYPOTHESIS:The Manchester procedure is a classic native tissue prolapse technique with low recurrence and low complication rate. vNOTES (vaginal natural orifice transluminal endoscopic surgery) is a vaginal approach to enter the intra or retroperitoneal space, with the guidance of endoscopic visualization. Different studies have shown women to prefer uterus-preserving correction of prolapse over hysterectomy, as they worry about complications, impact on sexual function and self- sense. At the same time, an increasing caution and awareness of mesh related complications has evolved, giving a need for the development of additional non-mesh uterus preserving surgical techniques for prolapse. The aim with the video is to show a new surgical technique for prolapse, combining the Manchester procedure with vNOTES retroperitoneal non-mesh promontory hysteropexy.

vNOTES hysterectomy is a scarless minimally invasive method with a vaginal approach to the abdominal cavity combined with endoscopic overview. Studies have shown that patients who underwent vNOTES hysterectomy had less pain and shorter hospital stay than after laparoscopic hysterectomy.

Acquired arteriovenous malformations (AVM) of the uterus can cause life-threatening vaginal bleeding and are associated with previous pregnancy, abortion or pelvic trauma. The pathophysiology is not well understood and the diagnosis is usually made by greyscale ultrasound often with nonspecific imaging findings, hence making it difficult to establish a correct diagnosis and therefore also the true incidence. However, case reports have previously described a connection between AVM formation and placental invasive disorders. In this report we demonstrate a case of a woman diagnosed with an AVM by ultrasound, presenting with menorrhagia after a termination of pregnancy, resulting in an emergency hysterectomy where subsequently a vascular malformation was found in conjunction with a remnant of a placenta increta and a placental site nodule. We hence suggest the hypothesis that these conditions are part of the same pathological process in the spectrum of abnormal invasive placental disorders, and that in the setting of previous trophoblastic processes, vascular malformations may mimic AVMs and ought not in fact to be considered as true AVMs.

(Acta Obstet Gynecol Scand. 2022;101:1026–1032) The rates of cesarean delivery (CD) have climbed worldwide over the past 3 decades. While the increased risks of serious complications associated with CD compared with vaginal delivery (VD) have been well described, there is a lack of information on the risks and benefits of CD without medical indication, or “CD on maternal request.” This study compared the rates of short-term complications, including postpartum thromboembolism and infections, with planned, requested CD compared with planned VD.

Introduction Obstetric anal sphincter injuries (OASIS) are severe complications to vaginal births with potentially serious long-term consequences and large impact on quality of life. The aim was to determine risk and protective factors for OASIS. Material and methods We performed a retrospective register-based observational study. A cohort of 988 988 singleton term deliveries 2005-2016 in Sweden were included. Data from the Swedish Medical Birth Registry and Statistics Sweden were extracted to identify cases of OASIS and maternal and fetal characteristics. Modified Poisson Regression analyses were performed to assess risk factors. Results The rate of OASIS was 3.5% (n = 34 583). Primiparity (adjusted risk ratio [aRR] 3.13, 95% CI 3.05-3.21), vacuum extraction (aRR 2.79, 95% CI 2.73-2.86), forceps (aRR 4.27, 95% CI 3.86-4.72), and high birthweight (aRR 2.61, 95% CI 2.50-2.72) were associated with a significantly increased risk of OASIS. Increasing maternal age and decreasing maternal height also increased the risk of OASIS. Obesity increased the risk of OASIS (aRR 1.04, 95% CI 1.04-1.08), if fetal birthweight was not adjusted for. Smoking (aRR 0.74, 95% CI 0.70-0.79) and low maternal education (aRR 0.87, 95% CI 0.83-0.92) were associated with a decreased frequency of reported OASIS. Previous cesarean section increased the risk of OASIS (aRR 1.41, 95% CI 1.36-1.47). Conclusions Primiparity, instrumental delivery, and high birthweight significantly increased the risk of OASIS. Obesity, low height, increasing age, and previous cesarean section also increased the risk whereas smoking and low maternal educational level were associated with a lower OASIS rate.

Objective To investigate the risk of stillbirth or neonatal death before 45 post-menstrual weeks in relation to gestational duration, stratified by body mass index (BMI) and parity. Design Retrospective study. Setting Data from the Swedish Medical Birth Register. Population Singleton, cephalic births at between 39(+0) and 42(+2) weeks of gestation, 2005-2016 (n = 892 339). Methods Relative risk ratios for mortality in relation to gestational duration were stratified by parity and BMI, and were adjusted for maternal age, smoking, country of birth and educational level. Main outcome measures Primary outcome: stillbirth or neonatal death before 45 post-menstrual weeks. Secondary outcome: stillbirth. Results Among children of primiparous women, children born at 41(+3) weeks of gestation, or later, were at increased risk of stillbirth or neonatal death before 45 post-menstrual weeks compared with children born between 39(+0) and 40(+2) weeks of gestation (aRR 1.29, 95% CI 1.10-1.52). For primiparous women with BMIs of <25, 25-29.9 and >= 30 kg/m(2), the corresponding aRRs were: 1.04 (95% CI 0.81-1.34), 1.25 (95% CI 0.94-1.66) and 1.52 (95% CI 1.10-2.10), respectively. No significant increase in risk with gestational age was detected for multiparous women, regardless of BMI class. Among primipara, the risk of stillbirth increased with gestational duration in all BMI classes, with the highest risk increase for BMI >= 30 kg/m(2), from 0.8/1000 at 40(+3)-40(+6) weeks of gestation to 4.0/1000 at 42(+0)-42(+2) weeks of gestation. Conclusions At 41(+3)-42(+2) weeks of gestation, pregnancy duration was associated with an increased risk for stillbirth or neonatal death before 45 post-menstrual weeks among primiparous women, especially among women who were obese. For multiparous women, no significant association between gestational duration and mortality was found. Tweetable abstract In term pregnancies the risk for stillbirth and neonatal death is affected by gestational age, parity and BMI.

Introduction There is growing evidence that induction of labor at 41 completed weeks improves neonatal outcome, at least among primiparous women. This study was performed to investigate whether maternal body mass index (BMI) should be considered when deciding on timing of intervention in term pregnancies. Material and methods The study design was a historical cohort study using data from the Swedish Medical Birth Register, singletons in cephalic presentation with births 39+0 to 41+6 weeks, with available information on maternal BMI 2005-2017 (n = 352 567). Modified Poisson regression analyses were used to investigate the association between gestational duration and stillbirth or death before 45 postmenstrual weeks (primary outcome) and Apgar score <7 at 5 minutes (secondary outcome) by BMI, respectively. Adjustments were made for maternal age, smoking, country of birth and educational level. Results The adjusted relative risk (ARR) of stillbirth or death before 45 weeks among infants born at 41+0 to 41+6 vs 40+0 to 40+6 weeks, was 1.26 with a 95% confidence interval (CI) of 1.07-1.48. Among women with BMI >= 30, the offspring mortality risk in pregnancies lasting 39+0 to 39+2 weeks was significantly above the corresponding risk among women of normal BMI who delivered at 41+0 to 41+2 weeks (ARR = 1.95; 95% CI 1.07-3.56) but no statistically significant heterogeneity was found regarding the magnitude of the association between gestational duration and offspring mortality. The ARR, for Apgar <7 at 5 minutes (41+0 to 41+6 vs 40+0 to 40+6 weeks, regardless of BMI), was 1.36 (95% CI 1.27-1.45). The risk for low Apgar score at 41+0 weeks was 1.5% among all children regardless of maternal BMI. Among children to women with BMI >= 30, this magnitude of risk was found already at 39+3 weeks. Conclusions In primiparous women with obesity the risk of stillbirth or death before 45 postmenstrual weeks were increased throughout all full-term gestational age categories, compared with women with overweight or normal BMI. Children to obese women had the same risk for Apgar scores <7 at 5 minutes compared with women overall at earlier gestational age. The results suggest that maternal BMI needs to be considered when discussing timing of elective induction in term healthy pregnancies of primiparous women.
