Surgeon reported measures of stress and anxiety prior to and after elective gynecological surgery.

INTRODUCTION: Performing surgical procedures is a recognized source of stress for surgeons. Vocational stress is an important contributor to performance, patient care, and burnout with dispositional and environmental factors contributing. Accurately assessing surgeon stress is critical to measuring effectiveness of stress reduction programs. The primary aim was to identify differences between surgeons' self-reported anticipated stress and anxiety prior to gynecological surgery, compared with their recollection of experienced stress and anxiety during surgery. Secondary aims assessed any differences by level of training, surgical type, and surgeon role. MATERIAL AND METHODS: Attending and resident gynecologists performing routine elective surgeries completed a visual analog scale (VAS) assessing perceived stress and the State-Trait Anxiety Inventory (STAI) prior to and immediately after completing 161 elective surgeries including total laparoscopic hysterectomy, laparoscopic excision of moderate-severe endometriosis, or hysteroscopic myomectomy. RESULTS: Eight attending gynecologists and nine residents participated. Residents commenced as primary surgeon in 62/90 (69%) procedures. Stress experienced during surgery was greater than anticipated in 92/161 (57%) surgery episodes (mean VAS increase: 3.9; 95% CI: 1.1-6.8, p = 0.009). State anxiety was greater than anticipated in 99/161 (62%) episodes (mean state anxiety increase: 4.4; 95% CI: 3.0-5.8, p < 0.001). Greater preprocedural anticipatory stress and anxiety was observed in residents vs. attending gynecologists (VAS 51.9 vs. 22.8, p < 0.001; state anxiety 38.3 vs. 28.1, p < 0.001) and in primary vs. assistant surgeons (VAS 47.2 vs. 29.9, p < 0.001; state anxiety 36.9 vs. 28.3, p < 0.001). Intraoperative stress and anxiety were greater in primary surgeons (VAS 50.4 vs. 30.5, p < 0.001; anxiety 41.3 vs. 32.5, p < 0.001) and residents (VAS 43.4 vs. 31.7, p < 0.001; anxiety 53.5 vs. 33.7, p < 0.001) compared with assistants and attending gynecologists. Perceived stress and anxiety were positively correlated at both timepoints (r = 0.68, p < 0.001; r = 0.82, p < 0.001). CONCLUSIONS: When asked to reflect on stress experienced during surgery, our data show that stress during surgery is greater than anticipated for many surgical episodes. Self-reported stress symptoms commence prior to surgery and are more commonly reported by surgeons operating as primary surgeon and by those in training. Future research should focus on determinants of presurgical stress and examine when stressors become inhibitory to performance.

A Prospective Study of Bladder Function Following Endometriosis Surgery With Up to Eight years Follow-up.

STUDY OBJECTIVE: To assess long-term urinary function for women having laparoscopic surgery for endometriosis. DESIGN: Institutional Review Board-approved nested cohort study within a larger randomized controlled trial assessing urinary function following any benign laparoscopy for gynecological presentations. SETTING: Two tertiary-level university-affiliated hospitals. PATIENTS: Women with histologically confirmed endometriosis within the randomized controlled trial between April 2012 and November 2019, where baseline urinary function was determined. INTERVENTIONS: Women with histologically confirmed endometriosis were contacted between February and October 2020, and urinary function was re-assessed. MEASUREMENTS AND MAIN RESULTS: Urinary function was assessed using validated questionnaires across the domains of filling, voiding, incontinence, and quality of life determined distant from surgery. Higher scores correlated with a greater severity of symptoms. From 518/711 (72.9%) women with histologically confirmed endometriosis, 289/518 (55.8%) consented to the nested study. At a mean of 50 months (range 12-103 months) post-operatively, 35 participants (12.1%) had sought treatment for bladder symptoms, and 81 participants (28.0%) reported at least one urinary tract infection since their index surgery. There was a significant worsening of symptoms for filling, voiding, incontinence, and quality of life pre-operative to post-operatively (2.27 vs 3.32, 0.93 vs 2.02, 1.06 vs 2.32, 0.83 vs 2.13 respectively, p <.001). There was no statistically significant difference in urinary questionnaire scores in participants with and without uterovesical endometriosis. There was no statistically significant difference in any parameter when comparing any revised American Society of Reproductive Medicine (rASM) stage of endometriosis. Participants who had post-operative urinary retention reported a higher mean voiding score than those who did not (3.24 vs 1.94, p = .017), while participants with post-operative urinary tract infection reported a higher mean frequency score than those who did not (5.17 vs 3.24, p = .016). CONCLUSION: This study suggests a decline in urinary function over time following laparoscopic surgery for endometriosis that is not dependent on the severity or location of the disease.

Perfusion magnetic resonance imaging in Asherman syndrome.

BACKGROUND: Microvascular scarring compromises the functionality of the endometrium, and vascular flow at the junctional zone (JZ) may be the key to understanding poor reproductive outcomes in women with Asherman syndrome (AS). AIMS: To investigate whether vascular perfusion of the uterus, measured by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is impaired in women with intrauterine adhesions (IUA) and AS. MATERIALS AND METHODS: A prospective observational cohort pilot study of 23 women with IUA treated with hysteroscopic synecholysis and a control group of two patients with cervix cancer were subject to DCE-MRI with gadolinium to assess uterine vascularity. Twelve regions of interest (ROIs) were allocated on the DCE-MRI image incorporating the JZ, with control ROI placed at the psoas muscle. Individual ROIs were compared to the mean total perfusion (TP) in the same uterus. Pre- and post-operative perfusion analyses were performed on five women. Receiver operator curves (ROC) were used to analyse MRI as a predictor of IUA. RESULTS: There was no significant difference in perfusion; a trend toward reduced perfusion was observed in women with IUA compared to the controls. The ROC was predictive of higher-grade and inoperable IUA. CONCLUSIONS: Reduced perfusion on DCE-MRI as assessed by ROC predicted higher-stage AS. The results of this study support further investigation of DCE-MRI as a prognostic tool for AS prior to surgical intervention to assist in providing prognostic guidance for women suffering from AS.

A study protocol for live and deceased donor uterus transplantation as a treatment for women with uterine factor infertility.

AIM: Uterus transplantation (UTx) is an emerging treatment option for women with uterine factor infertility (UFI) or the absence of a functional uterus. This is the study protocol for the first human UTx clinical trial in Australia. MATERIALS AND METHODS: This protocol outlines the approved training program used to plan, diagnose, screen, and treat patients who may be eligible for UTx using living and deceased donors. This multi-site clinical research study includes three tertiary hospital sites within New South Wales (NSW), Australia - Prince of Wales, Royal Hospital for Women and Westmead Hospitals. Our UTx protocol is based on that used by our collaborative partner, the inaugural UTx team in Gothenburg, Sweden. The Swedish UTx team provides ongoing preceptorship for the Australian UTx team. Ethics approval for six UTx procedures using living or deceased donors (Western Sydney Local Health District Human Research Ethics Committee: 2019/ETH138038) was granted in 2020. RESULTS: Results from surgeries and live births will be published. Data will be prospectively entered into the registry of the International Society of Uterus Transplantation (ISUTx), a sub-section of The Transplantation Society (TTS). TRIAL ID: ACTRN12622000917730. DISCUSSION: A multidisciplinary research team has been formed between three tertiary hospitals in Sydney - The Royal Hospital for Women, Prince of Wales and Westmead Hospitals; and with the Swedish UTx, University of Gothenburg. The Swedish team pioneered animal and human UTx studies since 1998, including publishing the first live birth after UTx. (1) This Australian trial commenced in January 2023. CONCLUSION: Uterus transplantation gives women with UFI the opportunity to be gestational and genetic mothers. It is a complex procedure for both the donor and recipient, with medical and surgical risks. An extensive multidisciplinary approach is required to optimise patient safety and graft outcomes. This protocol outlines our Australian UTx team strategy for screening, recruitment, surgical approach, and clinical management of UTx recipients and donors.

Immediate versus delayed urinary catheter removal following non-hysterectomy benign gynaecological laparoscopy: a randomised trial.

OBJECTIVE: To compare rates of urinary retention and postoperative urinary tract infection between women with immediate versus women with delayed removal of indwelling catheter following benign non-hysterectomy gynaecological laparoscopic surgery. DESIGN: This randomised clinical trial was conducted between February 2012 and December 2019, with follow-up to 6 weeks. SETTING: Two university-affiliated teaching hospitals in Sydney, Australia. POPULATION: Study participants were 693 women aged 18 years or over, undergoing non-hysterectomy laparoscopy for benign gynaecological conditions, excluding pelvic floor or concomitant bowel surgery. METHODS: Three hundred and fifty-five participants were randomised to immediate removal of urinary catheter and 338 participants were randomised to delayed removal of urinary catheter. MAIN OUTCOME MEASURES: The co-primary outcomes were urinary retention and urinary tract infection. Secondary outcomes included hospital readmission, analgesia requirements, duration of hospitalisation and validated bladder function questionnaires. RESULTS: Urinary retention was higher after immediate compared with delayed removal of the urinary catheter (8.2% vs 4.2%, RR 1.8, 95% CI 1.0-3.0, p = 0.04). Although urinary tract infection was 7.2% following delayed removal of the urinary catheter and 4.7% following immediate removal of the urinary catheter, the difference was not statistically significant (RR 0.7, 95% CI 0.3-1.2, p = 0.2). CONCLUSIONS: There is an increased risk of urinary retention with the immediate compared with the delayed removal of the urinary catheter following benign non-hysterectomy gynaecological laparoscopic surgery. The difference in urinary tract infection was not significant. There is 1/12 risk of re-catheterisation after immediate urinary catheter removal. It is important to ensure that patients report normal voiding and emptying prior to discharge, to reduce the need for readmission for the management of urinary retention.

Acute Biological Changes in Gynecologic Surgeons during Surgery: A Prospective Study.

STUDY OBJECTIVE: To assess changes in biological measures of acute stress in surgeons during surgery in real-world settings DESIGN: A prospective cohort study. SETTING: A tertiary teaching hospital. PATIENTS: 8 consultant and 9 training gynecologists. INTERVENTION: A total of, 161 elective gynecologic surgeries of 3 procedures: laparoscopic hysterectomy, laparoscopic excision of endometriosis, or hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: Changes in surgeons' biological measures of acute stress while undertaking elective surgery. Salivary cortisol, mean and maximum heart rate (HR), and indices of the HR variability were recorded before and during surgery. From baseline to during surgery over the cohort, salivary cortisol decreased from 4.1 nmol/L to 3.6 nmol/L (p = .03), maximum HR increased from 101.8 beats per min (bpm) to 106.5 bpm (p <.01), root mean square of standard deviation decreased from 51.1 ms to 39.0 ms (p <.01), and standard deviation of beat-to-beat variability decreased from 73.7 to 59.8 ms (p <.01). Analysis of individual changes in stress by participant-surgery event by paired data graphs reveal inconsistent direction of change in all measures of biological stress despite stratification by surgical experience, role in surgery, level of training, or type of surgery performed. CONCLUSION: This study measured biometric stress changes at both a group and individual level in real-world, live surgical settings. Individual changes have not previously been reported and the variable direction of stress change by participant-surgery episode identified in this study demonstrates a problematic interpretation of mean cohort findings previously reported. Results from this study suggest that either live surgery with tight environment control or surgical simulation studies may identify what, if any, biological measures of stress can predict acute stress reactions during surgery.

Four-dimensional ultrasound biometry following botulinum toxin type A injection to the pelvic floor.

AIMS: The objective of this study was to provide follow-up data on four-dimensional ultrasound (4DUS) morphometry for women having botulinum toxin type A (BoNT-A) treatment of pelvic floor tension myalgia (PFTM). MATERIALS AND METHODS: A prospective cohort study was performed from October 2013 to June 2018, recruiting women scheduled for BoNT-A injection in the pelvic floor musculature. Translabial 4DUS, vaginal pressure assessment by manometry and pain visual analog scales (VAS) were performed on all women before injection and again at 4, 12, and 26 weeks. The BoNT-A injection was performed under 4DUS guidance. RESULTS: Twenty-nine women had 44 injections over the course of the study. Although improvements were seen in VAS scores for dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia, there were no significant differences in ultrasound biometry at either rest, Valsalva, or on contraction when comparing postinjection measurements at 4, 12, and 26 weeks with pre-injection baseline. Similarly, vaginal pressure readings at rest demonstrated a significant improvement throughout the 4, 12, and 26 week follow-up, with a reduction in maximal contraction at 4 and 12 but not 26 weeks. CONCLUSIONS: This study demonstrates that 4DUS biometry of the pelvic floor does not correlate with clinical pain and vaginal pressure outcomes for BoNT-A injection in the context of PFTM.

A systematic review of diagnostic tests to detect pelvic floor myofascial pain.

INTRODUCTION AND HYPOTHESIS: Myofascial pain arising from pelvic floor muscles occurs in women with vaginismus, interstitial cystitis and endometriosis but is often overlooked. The aim is to examine alternative diagnostic tests to detect pelvic floor myofascial pain compared with standardized vaginal palpation of pelvic floor muscles as the reference test. METHODS: A systematic review was prospectively conducted (PROSPERO-CRD42020183092) according to PRISMA guidelines. Databases searched included Ovid Medline 1946-, Embase 1957-, Scopus 1960-, Cochrane Combined, Clinical trials, Google Scholar (top 200 articles), Web of Science, TRIP, BIOSIS, DARE, CINHAL, EmCare, PEDro, ProQuest and EBSCOhost up to July 2020. Articles were independently screened by two authors and assessed for bias using QUASDAS-2 tool. RESULTS: A total of 26,778 articles were screened and 177 were selected for full text review, of which 5 were selected for final analysis. Five studies included 9694 participants of which 1628 had pelvic floor myofascial pain. Only one study reported data to calculate sensitivities and specificities of the index test, which utilized a score of > 40 on the Central Sensitization Inventory to detect women with pelvic floor myofascial pain and revealed a sensitivity of 34.8% and a specificity of 84.9% compared to the reference test. CONCLUSIONS: This systematic review did not reveal any diagnostic test superior to the pre-defined reference test. There is a lack of consensus on the definition of pelvic floor myofascial pain and a lack of a validated diagnostic criteria which must be addressed to progress with meaningful research in this field.

A Double-blinded, Randomized, Placebo-controlled Trial of Antibiotic Prophylaxis in Elective Non-hysterectomy Laparoscopic Surgery for Benign Gynecologic Conditions: A Pilot Study.

STUDY OBJECTIVE: To determine the feasibility of a double-blinded randomized, placebo-controlled study in determining the efficacy of antibiotic prophylaxis in preventing postoperative infections (POIs) in elective nonhysterectomy laparoscopic procedures for benign gynecologic conditions. DESIGN: Double-blinded, randomized, placebo-controlled trial. SETTING: University-affiliated tertiary referral hospital in Sydney, Australia. PATIENTS: Women older than 18 years undergoing elective nonhysterectomy laparoscopic procedures for benign gynecologic conditions were eligible for the study and approached. INTERVENTIONS: Before surgery, participants were randomized to receive either 2-g cephazolin or placebo (10-mL normal saline) administered by the anesthetist. Participants and other research staff were blinded to group allocation. MEASUREMENTS AND MAIN RESULTS: The primary outcome was study feasibility measured by recruitment rates, compliance rates of drug administration, compliance rates of delivery, maintenance of double blinding, and follow-up rates. Secondary outcomes included rate of POIs, length of hospitalization, readmission to hospital, unscheduled presentations to healthcare facilities, and antibiotic-related reactions. Between February 2019 and March 2021, 170 patients were approached with 117 participants (68.8%) recruited and randomized. The study had a high compliance rate of trial drug delivery (95.7%) and a high follow-up rate (99.1%). CONCLUSION: This pilot study has demonstrated feasibility of a large-scale study with a recruitment rate of 68% of patients approached and excellent trial drug delivery and follow-up rates. As anticipated, it is underpowered for identifying clinically significant findings for POI rates. A large-scale study is appropriate and essential to determine the health-related risks of antibiotic prophylaxis with an emphasis on antimicrobial stewardship. The sample size for a large-scale study is 1678 participants based on infection rates in this pilot study.

A review of gynaecological surgical practices for trainees and certified specialists in Australia by volume using MBS and AIHW databases.

BACKGROUND: There is a finite volume of surgery performed annually by trainees and certified specialists alike. The detailed assessment of this surgical substrate is important, since it guides true exposure in gynaecological surgical training and practice after fellowship. AIMS: This study quantifies the volume and profile of major gynaecological surgical procedures performed in Australia within a specified five-year period and discusses the implications for training and practice. MATERIALS AND METHODS: Australian Institute of Health and Welfare data were examined to quantify the total number of major gynaecological procedures performed between 2013 and 2018. Medicare data were analysed to quantify the number of billed procedures. These data were compared with published Australian RANZCOG trainees and operative gynaecologists, to estimate the potential annual average exposure for each procedure. RESULTS: Major open, laparoscopic and vaginal surgeries constitute less than 27% of the 600 000 gynaecological procedures performed annually in Australia. Most major gynaecological surgeries are performed at rates lower than 12 cases per year for both trainees and specialists. Over the study period, laparotomies, vaginal hysterectomies and continence procedures decreased, and operative laparoscopies and laparoscopic hysterectomies increased. CONCLUSIONS: The volume of available major gynaecological procedures in Australia may not allow sufficient exposure for optimal training and practice for all trainees and specialists in operative gynaecology. This shortfall may compromise the ability to obtain and maintain proficiency in some core gynaecological operative procedures.

Endometriosis and other causes of pelvic pain in perspective.

Assuming we know the perfect management for endometriosis or pelvic pain is folly, but we should be celebrating our successes, not abandoning everything that we currently know.

Effect of Fractional Carbon Dioxide Laser vs Sham Treatment on Symptom Severity in Women With Postmenopausal Vaginal Symptoms: A Randomized Clinical Trial.

Importance: Postmenopausal vaginal symptoms are common and frequently detrimental to a woman's quality of life. Fractional carbon dioxide vaginal laser is increasingly offered as a treatment, but the efficacy remains unproven. Objective: To determine the efficacy of fractional carbon dioxide laser for treatment of vaginal symptoms associated with menopause. Design, Setting, and Participants: A double-blind, randomized, sham-controlled trial with 12-month follow-up was undertaken at a single tertiary referral hospital in Sydney, Australia. Enrollment commenced on September 19, 2016, with final follow-up on June 30, 2020. Participants were postmenopausal women with vaginal symptoms substantive enough to seek medical treatment. Of 232 participants approached, 85 were randomized. Interventions: Three treatments using a fractional microablative carbon dioxide laser system performed 4 to 8 weeks apart, with 43 women randomized to the laser group and 42 to the sham group. Main Outcomes and Measures: The co-primary outcomes were symptom severity assessed using a visual analog scale (VAS; range, 0-100; 0 indicates no symptoms and 100 indicates the most severe symptoms) and the Vulvovaginal Symptom Questionnaire (VSQ; range, 0-20; 0 indicates no symptoms and 20 indicates the most severe symptoms) at 12 months. The minimal clinically important difference was specified as a 50% decrease in both VAS and VSQ severity scores. There were 5 prespecified secondary outcomes, including quality of life (range, 0-100; higher scores indicate better quality of life), the Vaginal Health Index Score (range, 5-25; higher scores indicate better health), and vaginal histology (premenopausal or postmenopausal status). Results: Of 85 randomized participants (mean [SD] age, 57 [8] years), 78 (91.7%) completed the 12-month follow-up. From baseline to 12 months, there was no significant difference between the carbon dioxide laser group and the sham group in change in symptom severity (VAS score for overall vaginal symptoms: -17.2 vs -26.6; difference, 9.4 [95% CI, -28.6 to 47.5]; VAS score for the most severe symptom: -24.5 vs -20.4; difference -4.1 [95% CI, -32.5 to 24.3]; VSQ score: -3.1 vs -1.6; difference, -1.5 [95% CI, -5.9 to 3.0]). There were no significant differences between the laser and sham group in the mean quality of life score (6.3 vs 1.4; difference, 4.8 [95% CI, -3.9 to 13.5]) and Vaginal Health Index Score (0.9 vs 1.3; difference, -0.4 [95% CI, -4.3 to 3.6]) or in histological comparisons between laser and sham treatment groups. There were 16 adverse events in the laser group and 17 in the sham group, including vaginal pain/discomfort (44% vs 68%), spotting, discharge, and lower urinary tract symptoms. No severe adverse events were reported in either group. Conclusions and Relevance: Among women with postmenopausal vaginal symptoms, treatment with fractional carbon dioxide laser vs sham treatment did not significantly improve vaginal symptoms after 12 months.

Identifying the Problems of Randomized Controlled Trials for the Surgical Management of Endometriosis-associated Pelvic Pain.

OBJECTIVE: To report on randomized controlled trials (RCTs) that examine the surgical treatment of endometriosis-associated pelvic pain and to highlight their strengths and weaknesses. DATA SOURCES: We performed a systematic review of English-language, full-text articles addressing the surgical management of pain symptoms associated with endometriosis. The terms endometriosis, pain, surgery, laparoscopy, plasma, and laser were used for searches in Cochrane, MEDLINE, EMBASE, and clinical trial databases. Additional studies were identified from references in electronically located articles. METHODS OF STUDY SELECTION: A literature search was conducted by 2 authors, and abstracts were independently screened for inclusion, with the resolution of any discrepancy by a third author. Randomized studies that reported pain before and after surgery were eligible for inclusion. Supporting data from nonrandomized trials were used for discussion. The Cochrane risk-of-bias assessment was performed on included studies. TABULATION, INTEGRATION, AND RESULTS: Search results for available articles from 1996 to October 2019 revealed 594 potential studies, with 20 studies meeting the final inclusion criteria. Comparative studies of surgery vs no surgery for an effect on pain, surgical approach, the effect of different locations of disease on pain, nerve-dividing techniques for pain, and nerve-sparing effects for pain were studied. RCTs reported a substantial reduction in pain compared with no surgery in up to 80% of women; however, up to a third of women in these studies reported a placebo response. There was no evidence of a difference in pain reduction with the mode of surgery (laparoscopy, laparotomy, or robot-assisted laparoscopy). There is limited evidence stating that excision is superior to ablative surgery; however, there are confounders in the reporting of disease location and depth and the pain symptoms most affected. We need to reconsider the hypothesis that disc excision results in fewer complications and has superior outcomes to those of segmental resection in light of the first RCT on this subject. Nerve-dividing surgery for pain has been demonstrated to be of no value for uterosacral nerve ablation and/or division and of limited (if any) value for presacral neurectomy. CONCLUSION: Although surgical RCTs have always been difficult to undertake, there are 16 RCTs on endometriosis-associated pain. Ethical considerations, the equipoise of surgeons and participants, and follow-up duration are important parameters in establishing RCTs. In addition, we must be willing to accept and adopt the evidence when it does demonstrate a particular outcome, such as the fact that surgical uterosacral nerve disruption does not improve pain or that disc excision does not substantially reduce complications compared with segmental resection for bowel disease, as suggested by previous nonrandomized studies. If we accept that a well-conducted RCT provides best-quality evidence, then we should at least be open to the possibility that our long-held views may be challenged and changed with new science in our practice.

Live birth rate and obstetric complications following the hysteroscopic management of intrauterine adhesions including Asherman syndrome.

STUDY QUESTION: What are the live birth rate and risks of obstetric complications following the surgical management of intrauterine adhesions (IUA) such as Asherman syndrome (AS)? SUMMARY ANSWER: The live birth rate is 63.7%, and obstetric complications including placentation issues, prematurity and postpartum hysterectomy require that pregnancies in women after treatment for IUA should be considered moderate to high risk. WHAT IS KNOWN ALREADY: Studies reviewing short-term surgical, menstrual and fertility outcomes following hysteroscopic management are reassuring, with success correlated to the severity of IUA. There are limited data reporting live birth, neonatal and maternal complications. STUDY DESIGN, SIZE, DURATION: This retrospective study included all women treated for IUA by hysteroscopic synechiolysis under fluoroscopic guidance in two tertiary University-affiliated hospitals. All women reported at least one pre-treatment symptom including menstrual dysfunction, subfertility or pelvic pain and intended to become pregnant post-treatment. Survival curve analysis was performed for time to pregnancy, and obstetric data were collated from a National Obstetric Database for delivery and neonatal outcomes. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 154 women were included in the study. Surgical intervention involved hysteroscopic synechiolysis under fluoroscopic guidance until cavity restoration was confirmed. Questionnaires regarding fertility and its outcomes were sent to all women undergoing surgery, with analysis of menstrual, fertility rates and outcomes of those pregnancies including risks and complications to the woman and the offspring. MAIN RESULTS AND THE ROLE OF CHANCE: Women were followed up for a minimum of 1 year (range: 1-14 years) from index surgery. The chance of pregnancy was 98/124 (79.0% CI: 63.6, 83.1%) in women wishing to conceive and the chance of a live birth was 79/124 (63.7% CI: 51.3, 70.7%). The chance of a miscarriage was 29/124 (23.4% CI: 18.8, 37.1%). There were 93 live births in 79 women following surgery, with detailed obstetric data available for 85 of these births. They were complicated by abnormal placentation in 15/85 (17.6% CI: 13.0, 30.2%), postpartum hysterectomy in 4/85 (4.7% CI: -0.4, 7.0%), and prematurity in 25/85 (29.4% CI: 17.0, 35.3%) women. LIMITATIONS, REASONS FOR CAUTION: The retrospective nature of the study and extended follow-up time may cause selection and recall bias, however, pregnancy and its outcomes-particularly in women with problems of subfertility-are frequently key milestones, with birthdates readily recalled. Menstrual outcomes are more likely to be subject to recall bias. WIDER IMPLICATIONS OF THE FINDINGS: Our surgical data are similar to the published literature with reassuring short-term outcomes for menstruation and cavity reconstruction following surgery for IUA. Long-term outcomes including pregnancy rates were higher than published data, however, the obstetric and neonatal complication rates were increased, indicating a continuation of risk beyond infertility and into pregnancy. An altered biochemical or vascular environment is a possible explanation for impaired implantation resulting in poorer reproductive obstetric and neonatal outcomes. The relative rarity of IUA-particularly severe disease-makes prospective data collection difficult. Our data suggest that women with IUA should be treated as moderate-high risk obstetric patients in subsequent pregnancy and counselled appropriately.
