Inhaled methoxyflurane (Penthrox®) as a novel pain relief for outpatient hysteroscopy and other gynaecological procedures.

OBJECTIVE: Penthrox® (methoxyflurane) is a convenient, portable, self-administered disposable single-use handheld inhaler licenced as an emergency, rapid-onset, short-acting, analgesic in adult trauma patients. Outpatient hysteroscopy is one of the commonest procedures in contemporary gynecology but it can be associated with significant pain leading to poor patient experience and failed procedures. We evaluated the feasibility and acceptability of Penthrox® in women undergoing outpatient hysteroscopic procedures and its potential efficacy to reduce pain and improve patient experience. STUDY DESIGN: We conducted a prospective observational cohort study on women undergoing hysteroscopy or other intrauterine procedures, such as coil fitting, endometrial biopsy, polypectomy, endometrial ablation and manual vacuum aspiration in an outpatient setting. Women were offered Penthrox® inhalers for pain control, instructed how to use it and asked to record the intra-procedural pain they expected and actually experienced using a 10 cm Visual Analogue Scale. The acceptability, side effects and ease of use of the Penthrox® device were also recorded. RESULTS: 122/146 (83.6 %) women chose to use Penthrox®. 116 out of the 122 (95.1 %) underwent an intrauterine procedure, including 59 hysteroscopic polypectomies and 34 global endometrial ablations. The average pain expected during the procedure was 6.0 (SD = 2.8) and the pain experienced during the procedure was 5.1 (SD = 2.8). The intended procedure was completed in 117 (96 %) women. Penthrox® was considered easy to use by 118 (97 %) women and 111 (91 %) would use it again, although 22 (18 %) women would prefer general anaesthesia in the future. No adverse events occurred but 88 (72 %) women reported mild, self-limiting side effects. CONCLUSION: Penthrox® appears safe, feasible and acceptable as a pain relief option during outpatient hysteroscopy and other intrauterine procedures. The effectiveness of Penthrox® should be evaluated against conventional pain control in an adequately powered multicentre randomised controlled trial.

Pain experience with outpatient hysteroscopy: A prospective cohort study.

BACKGROUND: Abnormal uterine bleeding (AUB) affects women of all ages and is one of the most common reasons for referral to a gynaecological clinic. Operative hysteroscopic procedures allow for a see-and-treat approach to AUB, and these techniques have been shown to be feasible and acceptable in the outpatient setting. OBJECTIVE: To assess if there is an increase in pain scores for women who are undergoing an operative hysteroscopic procedure with Myosure LITE® (Hologic; mechanical hysteroscopic tissue removal system) compared to outpatient diagnostic hysteroscopy alone. STUDY DESIGN: A prospective cohort study was performed. All participants attending the outpatient hysteroscopy clinic at Mercy Hospital for Women completed a pre-and post-procedure questionnaire. This included a visual analogue scale (VAS) for any pre-existing pain, anticipated pain, and actual pain experienced during procedure. Factors influencing overall satisfaction and willingness to attend again were also assessed. Data was entered into RedCap® for analysis. A difference in VAS of 10 mm or more was considered clinically significant. An alpha of p < 0.05 was assigned for statistical significance. RESULTS: Between February 2020 and November 2022, 208 women underwent outpatient diagnostic hysteroscopy followed by an operative hysteroscopy with MyoSure®. To allow for standardisation of analgesia, only participants who had a cervical block before their Myosure® procedure were included for analysis (n = 111). There was statistical evidence (t(111) = 2.36, p = 0.02) of a lower mean VAS pain score for operative Myosure (36.5 mm, 95 % CI: 31.1-41.8 mm) compared to outpatient diagnostic hysteroscopy (44.1 mm, 95 % CI: 39.0-49.2 mm). The mean difference in VAS pain score was estimated as 7.7 mm (95 % CI: 1.2-14.1 mm) lower for Myosure compared to hysteroscopy. Given the threshold for clinical significance was considered as 10 mm difference in VAS, the variance in pain scores is under the likely clinically significant range. There was no significant difference in pain scores for diagnostic hysteroscopy with or without paracervical block (mean difference = 1.42; 95 % CI: -6.35 to 9.20). There was no association between pre-existing pain, and actual pain for hysteroscopy, or Myosure (p = 0.997 and p = 0.065 respectively). The anticipated pain score was weakly associated with actual pain during the operative Myosure procedure (p = 0.02), and with outpatient diagnostic hysteroscopy (p = 0.019). CONCLUSION: Outpatient hysteroscopy procedures are generally well tolerated. The pain experience with operative Myosure was less than that reported during the diagnostic hysteroscopy by the same patient although this is unlikely of clinical significance. Importantly, Myosure was not more painful than the initial diagnostic procedure, and most patients were satisfied with the outcome and would choose to have the procedure again in an outpatient setting. This is in keeping with other studies which have shown a high degree of patient tolerance and satisfaction with this approach.

Outpatient hysteroscopy impact on subsequent assisted reproductive technology: a systematic review and meta-analysis in patients with normal transvaginal sonography or hysterosalpingography images.

BACKGROUND: Standard management for intrauterine lesions typically involves initial imaging followed by operative hysteroscopy for suspicious findings. However, the efficacy of routine outpatient hysteroscopy in women undergoing assisted reproductive technology (ART) remains uncertain due to a lack of decisive high-quality evidence. This study aimed to determine whether outpatient hysteroscopy is beneficial for infertile women who have unremarkable imaging results prior to undergoing ART. METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines, incorporating data up to May 31, 2023, from databases such as PubMed, Embase, and the Cochrane Library. The primary outcome assessed was the live birth rate, with secondary outcomes including chemical pregnancy, clinical pregnancy rates, and miscarriage rates. Statistical analysis involved calculating risk ratios with 95% confidence intervals and assessing heterogeneity with the I2 statistic. RESULTS: The analysis included ten randomized control trials. Receiving outpatient hysteroscopy before undergoing ART was associated with increased live birth (RR 1.22, 95% CI 1.03-1.45, I2 61%) and clinical pregnancy rate (RR 1.27 95% CI 1.10-1.47, I2 53%). Miscarriage rates did not differ significantly (RR 1.25, CI 0.90-1.76, I2 50%). Subgroup analyses did not show a significant difference in clinical pregnancy rates when comparing normal versus abnormal hysteroscopic findings (RR 1.01, CI 0.78-1.32, I2 38%). We analyzed data using both intention-to-treat and per-protocol approaches, and our findings were consistent across both analytical methods. CONCLUSIONS: Office hysteroscopy may enhance live birth and clinical pregnancy rates in infertile women undergoing ART, even when previous imaging studies show no apparent intrauterine lesions. Treating lesions not detected by imaging may improve ART outcomes. The most commonly missed lesions are endometrial polyps, submucosal fibroids and endometritis, which are all known to affect ART success rates. The findings suggested that hysteroscopy, given its diagnostic accuracy and patient tolerability, should be considered in the management of infertility. DATABASE REGISTRATION: The study was registered in the International Prospective Register of Systemic Review database (CRD42023476403).

Patient experiences of outpatient hysteroscopy.

OBJECTIVES: Patient perspectives have an important role in improving the quality of outpatient hysteroscopy (OPH) services. Understanding women's experiences can help provide important insights regarding the OPH journey. The purpose of this paper is to share perspectives and reflect on the experiences of women that participated in a national benchmarking OPH survey. In addition, we explore the correlation between women's experience of OPH and reported pain scores. MATERIAL AND METHODS: Over a two-month period, 5151 women took part in the national OPH survey. Free text comments relating to women's OPH experience, collected as part of the survey, were subjected to qualitative analysis using NVivo 12 software to provide a better understanding of the OPH journey. In addition, correlations were drawn between the qualitative and quantitative data collected for pain scores and satisfaction using SPSS software. RESULTS: 1720 (33.3%) women provided comments on their OPH experience. Qualitative thematic analysis generated themes that were divided into positive (82%) and negative (7%) experiences of care. Potential areas of improvement in relation to the OPH service were highlighted in 11% of themes. Most women regarded OPH as a safe, tolerable, and well delivered outpatient service. Quantitative analysis showed that 1829 (35.5%) women reported procedural pain between 70 and 100 mm. These women reported equivalent quality of care on a 10 cm visual analogue scale (9.71 [SD1.04] vs. 9.76 [0.73]; P = 0.06) but were more likely to decline having the procedure done in the same way again (19.4% vs. 3.1%; RR 6.30, 95% CI 5.06 to 7.83) compared to women with pain scores < 70 mm. CONCLUSION: Qualitative data supports the usefulness, safety, tolerability, and acceptance of hysteroscopy in an outpatient setting by most women. However, the reasons for high procedural pain, poor tolerability and negative experiences warrant review and exploration of both individual patient and relevant institutional factors including training, equipment, and local processes.

Outpatient Hysteroscopic Polypectomy-A Retrospective Study Comparing Rigid and Semirigid Office Hysteroscopes.

Endometrial polyps are one of the most common pathological conditions in gynecology. Hysteroscopy is the gold standard for the diagnosis and treatment of endometrial polyps. The purpose of this multicenter, retrospective study was to compare patients' pain perception during an operative hysteroscopic endometrial polypectomy in an outpatient setting with two different hysteroscopes (rigid and semirigid) and to identify some clinical and intraoperative characteristics that are related to worsening pain during the procedure. We included women that underwent, at the same time as an diagnostic hysteroscopy, the complete removal of an endometrial polyp (using the see-and-treat strategy) without any kind of analgesia. A total of 166 patients were enrolled, of which 102 patients underwent a polypectomy with a semirigid hysteroscope and 64 patients underwent the procedure with a rigid hysteroscope. No differences were found during the diagnostic step; on the contrary, after the operative procedure, a statistically significant greater degree of pain was reported when the semirigid hysteroscope was used. Cervical stenosis and menopausal status were risk factors for pain both in the diagnostic step and in the operative one. Our results confirm that operative hysteroscopic endometrial polypectomy in an outpatient setting is an effective, safe, and well-tolerated procedure and indicate that it might be better tolerated if a rigid rather than semirigid instrument is used.

Diagnosing Endometrial Carcinoma in a Patient With Atrophic Endometrium and Postmenopausal Bleeding.

Endometrial carcinoma is the leading cause of gynecologic malignancies in the United States. Unlike other malignancies, endometrial carcinoma presents early with the most common clinical symptom being uterine bleeding (including irregular menses, inter-menstrual bleeding, and postmenopausal bleeding, or PMB). Hence, the evaluation of PMB should have efficient and effective strategies to prevent a missed diagnosis of malignancy and to facilitate an early diagnosis for potentially curative treatment. Transvaginal ultrasound is appropriate to evaluate PMB initially. If imaging reveals an endometrial thickness of ≤4 mm, endometrial sampling is not warranted, given the high negative predictive value (>99%) of this finding for endometrial carcinoma. In women with persistent or recurrent bleeding, if blind endometrial sampling does not show endometrial hyperplasia or malignancy, further testing with hysteroscopy with dilation and curettage is indicated. However, in cases of PMB with an endometrial thickness of ≤4 mm on transvaginal ultrasound, little information can be gained from endometrial sampling alone as the chance of getting an adequate sample is low and malignancy is rare. For such patients, outpatient hysteroscopy has become a convenient and cost-effective procedure that may be done before an endometrial sampling.

Pain Management during Office Hysteroscopy: An Evidence-Based Approach.

Background and Objectives: Hysteroscopy is a reliable technique which is highly useful for the evaluation and management of intrauterine pathology. Recently, the widespread nature of in-office procedures without the need for anesthesia has been requesting validation of practical approach in order to reduce procedure-related pain. In this regard, we performed a comprehensive review of literature regarding pain management in office hysteroscopic procedures. Materials and Methods: MEDLINE, EMBASE, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), Global Health, Health Technology Assessment Database and Web of Science, other research registers (for example Clinical Trials database) were searched. We searched for all original articles regarding pain relief strategy during office hysteroscopy, without date restriction. Results have been collected and recommendations have been summarized according to the Appraisal of Guidelines for Research and Evaluation (AGREE) tool. Moreover, the strength of each recommendation was scored following the Grading of Recommendations Assessment (GRADE) system, in order to present the best available evidence. Results: Both pharmacological and non-pharmacological strategies for pain management are feasible and can be applied in office setting for hysteroscopic procedures. The selection of strategy should be modulated according to the characteristics of the patient and difficulty of the procedure. Conclusions: Accumulating evidence support the use of pharmacological and other pharmacological-free strategies for reducing pain during office hysteroscopy. Nevertheless, future research priorities should aim to identify the recommended approach (or combined approaches) according to the characteristics of the patient and difficulty of the procedure.

Outpatient hysteroscopy is effective for uterine cavity evaluation following failed office-based endometrial biopsy.

BACKGROUND: Failure to obtain an office-based endometrial biopsy for abnormal uterine bleeding is not uncommon. Although operating room-based procedures are traditionally considered the gold standard assessment tool in these circumstances, outpatient hysteroscopy is a less invasive, more cost-effective, and safer alternative. However, there is no contemporary Canadian literature on the effectiveness of an outpatient approach for this specific population. OBJECTIVE: We aim to evaluate the effectiveness and outcomes of outpatient hysteroscopy for uterine cavity evaluation for patients who have failed an in-office endometrial biopsy attempt. METHODS: We conducted a retrospective cohort study of all patients referred to an academic outpatient hysteroscopy unit between January 2015 and January 2018, who underwent an outpatient hysteroscopy following failed endometrial biopsy. Data were collected from electronic medical records. RESULTS: Of the 407 consecutive patients who underwent an outpatient hysteroscopic procedure, 68 met inclusion criteria. Postmenopausal bleeding was the most common indication for initial biopsy, and most failures were attributed to cervical stenosis. Outpatient hysteroscopies were successfully completed in 96% of cases (n = 65/68). Failure resulted from either anxiety and discomfort (n = 2), or severe intrauterine adhesions (n = 1). Overall, 10% of patients subsequently required an operating room-based hysteroscopy, either to complete a myomectomy or polypectomy, or to allow general anesthesia. Outpatient hysteroscopy identified endometrial hyperplasia and cancer in 4.5% and 3% of patients, respectively. CONCLUSION: Outpatient hysteroscopy following unsuccessful office endometrial biopsy attempts appears to be a feasible, safe, and cost-effective investigation strategy that may prevent the need for an operating room-based procedure in 90% of cases.

Long-term patient satisfaction and removal rate after essure sterilization: a follow-up study.

BACKGROUND: The objective of our study was to assess the rate and causes for Essure® micro-insert system removal and patients' long term satisfaction rate with the procedure. METHODS: All patients who underwent Essure® hysteroscopic sterilization at our tertiary centre between years 2007 and 2018 were included in this follow-up study. A questionnaire was sent to all patients per standard mail. Patients who did not respond to questionnaires per mail, were called by phone. The satisfaction with the Essure® sterilization, as well as any additional procedures after the insertion or insertion-related complications were analysed. RESULTS: From the year 2007 to 2018, we performed 427 Essure® hysteroscopic sterilizations and of these, 329 patients responded to the questionnaire (response rate 77%). Ten patients (3%) had Essure® removal, two of them due to pain (0.6%). Patients were very satisfied with the procedure (9.5 on scale 0-10). Most patients (95.3%) would recommend the procedure to their friend. CONCLUSIONS: Essure® hysteroscopic sterilization is a procedure with a very high satisfaction rate and a very low removal rate due to sterilization-related complications. Trial registration Institutional review board of University medical centre Maribor approved the study, approval number UKC-MB-KME-73/19.

Warm saline effectiveness for pain relief in office hysteroscopy: A systematic review and meta-analysis of randomized controlled trials.

AIM: To evaluate the impact of warm distension medium versus room temperature distension medium on pain control among patients undergoing office hysteroscopy. METHODS: A systematic search was done in PubMed, Cochrane Library, Scopus, and ISI web of science from inception to October 2021. We selected randomized clinical trials (RCTs) compared warmed saline distension medium in the intervention group versus room temperature distension medium in the control group among women undergoing diagnostic and/or operative office hysteroscopy. Revman software was utilized for performing our meta-analysis. Our primary outcomes were pain scores evaluated by the visual analog scale (VAS) during and after the procedure. Our secondary outcome was the patient satisfaction between both groups. RESULTS: Five RCTs met our inclusion criteria with a total number of 441 patients. We found warm saline was linked to a significant reduction in the VAS pain score during the procedure compared to the control group (mean difference [MD] = -1.12, 95% confidence interval [CI] [-1.80, -0.45], p = 0.001). Moreover, the VAS pain score after the procedure was significantly declined among the warm saline group (MD = -0.62, 95% CI [-0.97, -0.27], p = 0.005). Interestingly, more patients were significantly satisfied with warm saline distension medium application compared to room temperature group (odds ratio [OR] = 3.71, 95% CI [2.01, 6.86], p < 0.001). CONCLUSIONS: Warm saline application in office hysteroscopy is effective in reducing pain during and after the procedure as well as improvement in patient satisfaction.

Hysteroscopic cervical features associated with difficult embryo transfer in unselected patients undergoing in vitro fertilization.

BACKGROUND: The most appropriate diagnostic tests for the assessment of the uterine cavity in patients undergoing standard infertility evaluation in daily practice remain unclear. Routine hysteroscopic uterine cavity evaluation before an in vitro fertilization-embyo transfer (IVF-ET) cycle is not a uniformly accepted procedure. However, cervical findings associated with difficult ET have rarely been reported in previous hysteroscopic studies. The main objective of this study was to examine the relationship between cervical finding under flexible outpatient hysteroscopy (OH) and difficult ET. METHODS: A cohort clinical study was conducted with 650 patients undergoing their first in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) from January 2010 to December 2017. Of them, 605 women with available embryos underwent transfer cycles. Outpatient hysteroscopies were scheduled during the follicular phase of the menstrual cycle, 1-3 months before starting IVF/ICSI treatment. RESULTS: Among the 650 women who underwent transvaginal sonography (TVS) and OH, abnormal sonographic findings were observed in 51 women (7.8%) in which submucous myoma, endometrial polyp, and endometrial hyperplasia were the most common. Abnormal hysteroscopic intracavitary findings were observed in 158 cases (24.3%) in which endometrial polyp, submucous myoma, and intrauterine adhesions were the most common. These results showed that TVS was specific (100%) but not sensitive (32.3%) compared with OH. Embryo transfer (ET) was difficult in 25% of women with cervical stenosis (CS) or tortuous cervical canal (TC) and was significantly more difficult in women in the TC group (30.7%) than in the CS group (19.6%). CONCLUSION: OH can identify cervical charactistics associated with a high incidence of difficult ET.

Determining the Optimal Time Interval between Vaginal Dinoprostone Administration and Diagnostic Office Hysteroscopy in Nulliparous Women: A Randomized, Double-blind Trial.

STUDY OBJECTIVE: To determine the optimal timing of vaginal dinoprostone administration before office hysteroscopy (OH) in nulliparous women. DESIGN: Randomized, double-blind trial. SETTING: Tertiary referral hospital. PATIENTS: A total of 180 nulliparous women undergoing diagnostic OH. INTERVENTIONS: We randomly allocated the women to long-interval or short-interval dinoprostone groups: three mg dinoprostone was administered vaginally 12 hours before OH in the long-interval group and 3 hours before OH in the short-interval group. MEASUREMENTS AND MAIN RESULTS: The primary outcome was pain during OH measured using a 100-mm visual analog scale (0 = no pain; 100 = worst pain imaginable). The secondary outcomes were ease of hysteroscope passage, patient satisfaction score, and drug-related adverse effects. The patients in the long-interval dinoprostone group had lower pain scores during OH (p <.001). Contrarily, pain scores 30 minutes after the procedure were similar in both groups (p = .1). The patient satisfaction score was higher and clinicians found hysteroscope passage through the cervical canal easier and quicker in the long-interval dinoprostone group than in the short-interval group (p <.001, p = .003, and p <.001, respectively). Side effects were comparable in both study groups. CONCLUSION: Vaginal dinoprostone administered 12 hours before OH was more effective than that administered 3 hours before OH in reducing pain during OH in nulliparous women, with easier hysteroscope insertion, shorter procedure duration, and higher patient satisfaction score.

Benchmarking services in outpatient hysteroscopy (OPH): A quality improvement project.

OBJECTIVE: To develop a survey evaluating women's experience of outpatient hysteroscopy (OPH) to generate data to benchmark OPH practice in the UK that can be used to optimise women's experience of OPH and improve services. DESIGN: Quality improvement project and a population-based national survey. SETTING: 77 hospitals with outpatient hysteroscopy (OPH) services across the UK collected data over two month-period (October-November 2019). POPULATION: 5151 women attending for outpatient hysteroscopy. METHODS: A new OPH-Patient Satisfaction Survey (OPH-PSS) was developed using a multi-disciplinary approach. Good practice guidance in hysteroscopy and existing survey's provided content for the survey. Pilot testing identified aspects of the women's OPH journey that contributed to a final survey. The final OPH-PSS was rolled out nationally to generate data for benchmarking OPH services. MAIN OUTCOME VARIABLE: The adequacy of OPH services reflected in women's experience of their OPH journey and the quality of care being delivered. RESULTS: The majority (3193, 76 %) of hysteroscopic procedures were recorded as diagnostic. Most (4485, 87 %) women received adequate information regarding their OPH. 4581, 89 % of women agreed that they were given an opportunity to discuss analgesia and 5033, 97 % of women felt involved in their care. As regards patient experience, although pain was reported by most women (4490, 87 %), just over half considered the degree of pain as slight. While (787, 15 %) felt pain throughout their OPH with 1 in 10 women feeling anxious. Although, 1217 (26 %) women experienced feeling faint most only felt this slightly. Overall, more than 90 % (4867) of women considered the OPH service good. The mean score rating for the overall level of care was considerably high (9.7/10). Comparative pain scores for OPH vs the worst pain felt during a menstrual period showed OPH procedures to be less painful except for endometrial ablation (P < 0.001). CONCLUSION: This novel survey, evaluating women's experience of OPH (OPH-PSS), provides a useful tool for benchmarking performance across different OPH units. Overall, the information provided to women and their subsequent experience of OPH is good, but pain is common.

A Systematic Review of the Effect of Type, Pressure, and Temperature of the Distension Medium on Pain During Office Hysteroscopy.

OBJECTIVE: To identify the optimal distension medium type, pressure, and temperature to minimize pain during office hysteroscopy. DATA SOURCES: MEDLINE, EMBASE, CINAHL, and CENTRAL were searched from inception to January 29, 2020. METHODS OF STUDY SELECTION: We included randomized controlled trials in which women undergoing office hysteroscopy were randomized to either a distension medium type, pressure, or temperature against a suitable control, where pain was an outcome. Data regarding feasibility, visualization, complications, and satisfaction were also collected. TABULATION, INTEGRATION, AND RESULTS: The literature search returned 847 studies, of which 18 were included for systematic review and 17 for meta-analysis. There was no significant difference in intraprocedural pain when comparing the use of normal saline against carbon dioxide (standardized mean difference [SMD], -0.12; 95% confidence interval [CI], -0.36 to 0.13). Subgroup analysis of high-quality studies revealed a statistically significant reduction in postprocedural pain with normal saline (SMD, -0.65; 95% CI, -1.14 to -0.16). Side effects were less frequent (Peto odds ratio, 0.29; 95% CI, 0.20-0.40) and patient satisfaction was higher (SMD, 1.39; 95% CI, 0.51-2.28) with normal saline compared with carbon dioxide. Pressures of ≤40 mm Hg reduced intraprocedural pain (SMD, -0.67; 95% CI, -1.09 to -0.26) at the expense of a higher proportion of unsatisfactory views (81%-89% at ≤40 mm Hg vs 95%-99% at ≥50 mm Hg). Postprocedural pain was reduced with lower filling pressures. Warming saline did not reduce intraprocedural pain (SMD, 0.59; 95% CI, -0.14 to 1.33). CONCLUSION: Normal saline, instilled at the lowest pressure to acquire a satisfactory view, should be used for uterine distension during office hysteroscopy to minimize pain.

Virtual reality for acute pain in outpatient hysteroscopy: a randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of virtual reality as a distraction technique in the management of acute pain and anxiety during outpatient hysteroscopy. DESIGN: Parallel group, prospective randomised controlled trial. SETTING: UK University Hospital. METHODS: Forty consenting, eligible women were randomised to virtual reality intervention (immersive video content as a distraction method) or standard care during outpatient hysteroscopy from August to October 2018. MAIN OUTCOME MEASURES: Pain and anxiety outcomes were measured as a numeric rating score (scale 0-10). RESULTS: Compared with standard care, women with virtual reality intervention experienced less average pain (score 6.0 versus 3.7, mean difference 2.3, 95% CI 0.61-3.99, P = 0.009) and anxiety (score 5.45 versus 3.3, mean difference 2.15, 95% CI 0.38-3.92, P = 0.02). CONCLUSION: Virtual reality was effective in reducing pain and anxiety during outpatient hysteroscopy in a mixed-methods randomised control trial. Its wide potential role in ambulatory gynaecological procedures needs further evaluation. TWEETABLE ABSTRACT: Virtual reality can be used as a part of a multimodal strategy to reduce acute pain and anxiety in patients undergoing outpatient hysteroscopy.

Electronic Continuous Pain Measurement vs Verbal Rating Scale in gynaecology: A prospective cohort study.

OBJECTIVE: To compare pain measured with a new electronic device - the Continuous Pain Score Meter (CPSM) - and the Verbal Rating Scale (VRS) during gynaecological procedures in an outpatient setting, and to correlate these outcomes with baseline anxiety and patient (in)tolerance to the procedure. STUDY DESIGN: This prospective cohort study was undertaken in two centres: a university hospital and a large teaching hospital in The Netherlands. Patients undergoing an outpatient hysteroscopy, colposcopy or ovum pick-up procedure for in-vitro fertilization in one of the two participating hospitals with availability of the CPSM were included. Pain was measured by both the CPSM and the VRS. Patient tolerance to the procedure was reported. Various outcomes of the CPSM were compared with those of the VRS and related to baseline anxiety scores. RESULTS: Ninety-one of 108 included patients (84 %) used the CPSM correctly during the procedure, and it was possible to analyse the CPSM scores for 87 women (81 %). The CPSM scores were all linearly related to the VRS. The peak pain score on the CPSM (CPSM-PPS) had the strongest correlation with the VRS score for all three procedures. Higher CPSM-PPS was related to patient (in)tolerance to the procedure (p = 0.03-0.002). Anxiety at baseline was not correlated with pain perception, except for VRS during colposcopy (r = 0.39, p = 0.016). CONCLUSION: The majority of patients were able to use the CPSM correctly, resulting in detailed information on pain perception for each individual pain stimulus during three outpatient gynaecological procedures. The CPSM-PPS had the strongest correlation with the VRS score and patient (in)tolerance to the procedure.

Cervical dilatation and preparation prior to outpatient hysteroscopy: a systematic review and meta-analysis.

BACKGROUND: There are uncertainties about the benefit of routine cervical preparation and/or cervical dilatation before outpatient hysteroscopy. OBJECTIVE: To determine if cervical preparation and/or routine mechanical dilatation reduces pain during outpatient hysteroscopy. SEARCH STRATEGY: MEDLINE, EMBASE, CINAHL and CENTRAL were searched on 19 October 2020, using keywords 'hysteroscopy', 'cervical preparation', 'cervical ripening', 'cervical dilatation', 'outpatient', 'office' and/or 'ambulatory' and associated medical subject headings. SELECTION CRITERIA: Randomised controlled trials investigating the benefit of cervical preparation and/or cervical dilatation on pain in women undergoing outpatient hysteroscopy were included. DATA COLLECTION AND ANALYSIS: Two independent reviewers selected eligible trials and extracted data on pain, feasibility, adverse events and satisfaction/acceptability for meta-analysis. MAIN RESULTS: The literature search yielded 807 records, of which 24 were included for review and 19 provided data for meta-analysis. No trials investigated the role of routine mechanical cervical dilatation. Cervical preparation significantly reduced pain during outpatient hysteroscopy; standard mean difference (SMD) -0.67, 95% confidence interval (CI) -1.05 to -0.29. Feasibility also improved as priming provided significantly easier hysteroscopic entry (SMD 0.89, 95% CI 0.32-1.46), greater cervical dilatation (SMD 0.81, 95% CI 0.08-1.53) and shorter procedural times (SMD -0.51, 95% CI -0.88 to -0.13). Cervical preparation, however, incurred significantly more adverse effects, mainly comprising genital tract bleeding, abdominal pain and gastrointestinal symptoms (odds ratio 2.94, 95% CI 1.58-5.47). There were limited data regarding satisfaction, acceptability and complications. CONCLUSIONS: Cervical preparation reduces pain and improves feasibility associated with outpatient hysteroscopy but increases the risk of adverse effects. TWEETABLE ABSTRACT: Cervical preparation before outpatient hysteroscopy reduces pain, enhances feasibility but increases adverse effects.

Should endometrial biopsy under direct hysteroscopic visualization using the grasp technique become the new gold standard for the preoperative evaluation of the patient with endometrial cancer?

OBJECTIVE: To investigate the diagnostic accuracy of endometrial biopsy performed with hysteroscopic direct visualization using the "grasp technique" for the detection of endometrial carcinoma (EC) histology type and tumor grade. METHODS: A cross-sectional study including the clinical and pathology records of patients with confirmed EC who underwent definitive surgery at University of Naples was performed. The preoperative diagnosis of endometrial tumor type and grade obtained using the hysteroscopy grasp technique was correlated with the final pathology specimens. Those results were compared to the diagnostic accuracy of the biopsies collected in a cohort of patients who underwent preoperative diagnostic hysteroscopy followed by blind endometrial biopsy using the Novak curette with subsequent surgical definitive treatment at University of Pisa. Statistical analysis was based on frequency data and diagnostic agreement of the pathology results. RESULTS: A total of 129 patients were included in the final analysis. An agreement rate of 104/106 (98.1%) for endometrioid type and 15/23 (65.2%) for non-endometrioid type was obtained between preoperative hysteroscopic grasp endometrial biopsy specimens and the final pathology with a coefficient k for G1, G2 and G3 tumors of 0.928, 0.925 and 0.974, respectively. When compared to 121 patients undergoing preoperative blind Novak endometrial biopsy, the hysteroscopic grasp technique was superior in agreement rates for tumor histotype [diagnostic accuracy (0.922 vs 0.890); K value (0.705 vs 0.642)] and grade when in presence of endometrioid type EC (K Cohen 0.354 for G1, 0.263 for G2 and 0.488 for G3). CONCLUSIONS: Preoperative hysteroscopic guided "grasp" endometrial biopsy provides a more accurate diagnosis of EC histology type and tumor grade when in presence of endometrioid type tumor compared to blind endometrial biopsy obtained using the Novak curette.

Evaluation and ranking of different interventions for pain relief during outpatient hysteroscopy: A systematic review and network meta-analysis.

AIM: To identify the highest-ranked pharmacological and nonpharmacological interventions for pain relief during outpatient hysteroscopy. METHODS: We conducted an online bibliographic search in different databases from inception till July 2019. We included randomized controlled trials assessing effect of pharmacological and nonpharmacological interventions on pain relief during outpatient hysteroscopy. Our main outcomes were pain scores at different endpoints of the procedure. We applied this network meta-analysis based on the frequentist approach using statistical package 'netmeta' (version 1.0-1) in R. RESULTS: The review included 39 randomized controlled trials (Women n = 3964). Misoprostol plus intracervical block anesthesia (mean difference [MD] = -3.32, 95% confidence interval [CI] [-6.06, -0.59]), misoprostol (MD = -1.92, 95% CI [-3.04, -0.81]) and IV analgesia (MD = -2.01, 95% CI [-3.27, -0.25]) were effective in reducing pain during the procedure compared to placebo. Ranking probability showed that misoprostol plus intracervical block anesthesia was the highest ranked pharmacological treatment for pain relief during the procedure (P score = 0.92) followed by misoprostol alone (P score = 0.78), and IV analgesia (P score = 0.76). Regarding nonpharmacological treatments, transcutaneous electrical nerve stimulation (TENS) showed a significant pain reduction compared to placebo (MD = -1.80, 95% CI [-3.31, -0.29]). TENS ranked as the best nonpharmacological treatment (P score = 0.80) followed by CO2 distention (P score = 0.65) and bladder distention (P score = 0.60). CONCLUSION: Combination of misoprostol plus local anesthesia appears to be the most effective pharmacological approach for pain reduction during and after outpatient hysteroscopy. Nonpharmacological approaches as TENS and bladder distention showed considerable efficacy but should be further investigated.

Does temperature of distending medium matter in outpatient hysteroscopy? A double-blinded cohort control observational study of room temperature versus warmed saline.

AIM: There is little data assessing outcomes of outpatient hysteroscopy using warmed versus room temperature saline. The aim of this study was to determine if the temperature of the distending medium during outpatient hysteroscopy affect ease of procedure, clarity of view, procedural discomfort/pain and patient satisfaction. METHODS: This was a double-blinded cohort control quasi-randomized prospective study involving 100 women undergoing outpatient diagnostic and operative hysteroscopy for abnormal uterine bleeding, intrauterine contraceptive devices retrieval and removal of endometrial polyps. Outpatient hysteroscopy was performed either with normal saline either at room temperature (control at 25°C) or warmed to body temperature (37°C). RESULTS: Confounding variables such as age, parity, previous cervical surgery, previous vaginal births, menopausal status and indications for hysteroscopy were similar in the room temperature (n = 48) and warmed saline (n = 52) groups. Mean procedure duration (256 vs 233 s), ease of entry (Visual Analogue Scale [VAS] 9.55 vs 9.4) and the clarity of view (VAS 9.02 vs 9.3) were statistically similar in both groups (all P > 0.05) as was discomfort experienced during hysteroscopy (VAS 6.6/10 vs 6.8/10) and at 5 min post-procedure (VAS 4.2/10 vs 3.2/10) (both P > 0.05). The likelihood of recommending the procedure to a friend was similar in both groups (mean VAS 6.9/10 vs 7.2/10; P = 0.1). CONCLUSION: The temperature of the distension medium did not influence ease of procedure, clarity of hysteroscopy view, procedural discomfort/pain and patient satisfaction. Patients were not any more likely to recommend the procedure to a friend in the warmed saline compared to the room temperature group.
