Fallopian tubal obstruction is associated with increased pain experienced during office hysteroscopy: a retrospective study

Risk of adverse pregnancy outcomes after abnormal hysterosalpingography

OBJECTIVE

To investigate the association between an abnormal hysterosalpingogram (HSG) and obstetrical and neonatal outcomes.

DESIGN

A retrospective cohort study comparing outcomes between women with normal versus abnormal tubal patency and uterine cavity on HSG.

RESULTS

Among 2181 women included in the study, 494 (22.6%) had an abnormal HSG. Of these, 207 (42%) presented with uterine abnormalities, 336 (68%) with tubal abnormalities and 49 (10%) with both. The study identified 232 clinical pregnancies in the abnormal HSG group and 814 pregnancies in controls. Women with abnormal HSG showed higher rates of preterm labour (PTL) compared to controls (13.6% vs. 7.7%, p < 0.05, n = 1687). Multivariate analysis revealed that any HSG abnormality was associated with an increased risk of PTL (aOR 2.39, 1.04-5.51). When analysing by type of abnormality, uterine abnormalities increased the risk of preeclampsia (aOR 2.86, 1.06-7.7) and low birthweight (aOR 2.31, 1.0-5.35), while tubal abnormalities were specifically associated with increased risk of PTL (aOR 3.87, 1.63-9.19).

CONCLUSION

An abnormal HSG study was associated with adverse obstetrical outcomes. Specifically, uterine abnormalities increased the risk of preeclampsia and birthweight below 10th percentile, while tubal abnormalities were associated with a heightened risk of PTL.

The Pivotal role of hysteroscopy in diagnosing subtle uterine lesions in infertile patients: Seeing the unseen can make the difference

BACKGROUND

Subtle uterine lesions are abnormal intracavitary conditions that, while not causing significant anatomical changes, can adversely impact fertility. Identifying these "subtle" lesions is challenging due to arbitrary interpretation, varied management strategies, unclear clinical significance, and insufficient clinician training in recognizing them. Hysteroscopy offers direct visualization and the capacity to obtain targeted biopsies, making it an invaluable tool for the diagnosis and treatment of these often overlooked conditions.

PURPOSE

The lack of standardized and universally accepted terminology complicates the diagnosis and treatment of subtle uterine pathologies. A thorough understanding of how to identify and effectively manage these lesions is essential for the treatment of infertile patients. This review summarizes the critical and evolving subtle uterine lesions that clinicians frequently overlook during hysteroscopic procedures, highlighting the importance of accurate identification and its potential to improve reproductive outcomes.

METHODS

This literature review followed the Scale for the Quality Assessment of Narrative Review Articles (SANRA) guidelines. All articles discussing infertility-related issues and subtle lesions diagnosable with hysteroscopy were deemed eligible for inclusion.

RESULTS

We identified several subtle uterine lesions that are often overlooked during routine hysteroscopic evaluations but can adversely impact fertility. These include morphological abnormalities such as the T-shaped uterus, cystic lesions of the uterine wall, adenomyosis, cervicitis, cervical and tubal endometriosis, and endometrial conditions such as chronic endometritis, thin endometrium and endometrial calcifications.

CONCLUSIONS

Effective diagnosis and treatment of subtle uterine lesions is essential to fertility care. Knowing which lesions are commonly missed and understanding their endoscopic features and potential clinical implications, is crucial for enhancing the diagnostic capacity of hysteroscopy. This, in turn, may improve reproductive outcomes and the overall quality of care of infertile patients.

Surgical parameters affecting procedure duration of hysteroscopic fibroid resection: results of a retrospective longitudinal study

PURPOSE

To identify and analyze the main surgical parameters affecting the operative time of hysteroscopic fibroid resection.

METHODS

This retrospective observational study included 65 cases of outpatient hysteroscopic fibroid resection performed between March 2021 and May 2023 in outpatient office setting. Patients aged 18-50 with various indications such as infertility, recurrent pregnancy loss, or abnormal uterine bleeding (AUB) were included. The operative time, fibroid size, FIGO classification, and fibroid localization were recorded and analyzed using ANOVA, Chi-square test, and linear regression models.

RESULTS

The average operative duration for all surgeries was 557.41 (± 449.52) s. A significant correlation between fibroid size and operative time was found in FIGO 0 (p = 0.0003) and FIGO 1 (p < 0.0001) subgroups, with weaker correlation in FIGO II (p = 0.039). FIGO I surgeries took significantly longer than FIGO 0 (p = 0.044), and fundal fibroids were associated with longer operative times compared to posterior fibroids (p = 0.0329).

CONCLUSION

The size and FIGO classification of fibroids significantly influence operative time during hysteroscopic resection. Smaller and more accessible fibroids (FIGO 0 and 1) are resected faster than those embedded deeper in the uterine wall (FIGO 2). Detailed preoperative evaluation of fibroid characteristics can better predict operative time, aiding in patient preparation and optimized analgesia and perioperative planning as well as optimizing the use of operating theater. Further studies with larger sample sizes are recommended to validate these findings and explore additional influencing factors.

What is the impact of simulation on the learning of hysteroscopic skills by residents and medical students? A systematic review

INTRODUCTION

Hysteroscopy is a critical procedure in gynecology for diagnosing and managing intrauterine pathology. Traditional hands-on training faces ethical and safety challenges, leading to an increased reliance on simulation training. This review systematically assesses the effectiveness of hysteroscopic simulation training in enhancing the technical skills of obstetrics and gynecology residents and medical students.

METHODS

A PRISMA-guided literature search was conducted, covering English-language articles from January 2000 to December 2023. Studies were selected based on pre-defined criteria, focusing on the impact of simulation training on the targeted educational group. Metrics for evaluating skill improvement included machine-recorded metrics, Objective Structured Assessment of Technical Skills (OSATS), and global rating scales.

RESULTS

The review included nine studies with varied designs, demonstrating significant improvements in hysteroscopic skills following simulation training. Virtual reality (VR) simulators showed substantial benefits in skill acquisition, while physical simulators provided valuable tactile feedback. However, long-term skill retention and the impact on non-technical skills were not adequately assessed.

CONCLUSIONS

Simulation-based training effectively enhances hysteroscopic skills in medical students and residents. Further research is needed to explore long-term skill retention and the development of non-technical competencies. Robust studies, including randomized trials, are required for definitive validation.

Hysteroscopy: where did we start, and where are we now? The compelling story of what many considered the "Cinderella" of gynecological endoscopy

Hysteroscopy has truly revolutionized the field of diagnostic and operative gynecology. It is presently regarded as the gold standard method for both the diagnosis and treatment of intrauterine diseases and it has fundamentally altered the way gynecologists treat patients with such conditions. These pathologies can now be diagnosed and treated in an outpatient setting, thanks to technological advancements and instrument downsizing. Two hundred years of development and notable innovation are now reflected in the present hysteroscopic practice. This review attempts to trace the boundaries-pushing history of hysteroscopy by highlighting the advancements in technology and the therapeutic and diagnostic benefits offered by this groundbreaking approach.

Immediate and delayed placement of the intrauterine device after abortion: a systematic review and meta-analysis

This article aims to report the comprehensive and up-to-date analysis and evidence of the insertion rate, expulsion rate, removal rate, and utilization rate of immediate placement of intrauterine devices (IUDs) versus delayed placement after artificial abortion. PubMed, Embase, Cochrane, Web of Science, CNKI, and Wanfang databases were comprehensively searched up to January 12, 2024 for studies that compared immediate versus delayed insertion of IUDs after abortion. The evaluation metrics included the number of IUD insertion after surgical or medical abortions, the frequency of expulsion and removal at 6 months or 1 year, the number of continued usage, pain intensity scores, the number of infections, the duration of bleeding, and instances of uterine perforation during or after IUD insertion. Ten randomized controlled articles were eligible, comprising 11 research projects, of which 3 projects involved the placement of an IUD after surgical abortion, and 8 projects involved the placement of an IUD after medical abortion. This included 2025 patients (977 in the immediate insertion group and 1,048 in the delayed insertion group). We summarized all the extracted evidence. The meta-analysis results indicated that for post-surgical abortions, the immediate insertion group exhibited a higher IUD placement rate than the delayed insertion group. After medical abortions, the immediate insertion group showed higher rates of IUD placement, utilization, and expulsion at 6 months or 1 year. The two groups showed no statistically significant differences in the removal rate, post-insertion infection rate, pain scores during insertion, and days of bleeding during the follow-up period. Compared to delayed placement, immediate insertion of IUDs can not only increase the usage rate at 6 months or 1 year but also enhance the placement rate.

Evaluation of tubal patency by hysterosalpingo-contrast Sonography (HyCoSy): Controversies, dilemmas and considerations

Evaluation of tubal patency is one of the vital steps in the process of female infertility management. Hysterosalpingo-contrast Sonography (HyCoSy) has become the first-line recommendation for evaluating tubal patency. However, there remain some controversies and dilemmas relevant to the evaluation of tubal patency by HyCosy, with no effective solution has been proposed or no consensus has been reached. Herein, combined with previous research and clinical experience, we conclude and analyze these controversies and dilemmas, aiming at offering our perspective on the opportunities and challenges which are faced by HyCosy.

Hysteroscopic Endometrial Ablation: From Indications to Instrumentation and Techniques-A Call to Action

The development of minimally invasive techniques has led to the creation of innovative alternatives in cases where traditional methods are not applicable. In modern gynecology, hysteroscopy has become the gold standard for the evaluation and treatment of intrauterine pathology. Endometrial ablation (EA) is a procedure that uses different types of energy to destroy the endometrium and is currently used as an alternative technique in cases of heavy menstrual bleeding when medical treatment has failed and uterine preservation is desired. The aim of this review was to evaluate the feasibility, safety, and clinical outcomes of hysteroscopic EA as an alternative in patients with abnormal uterine bleeding. A detailed computerized search of the literature was performed in the main electronic databases (MEDLINE, EMBASE, Web of Science, PubMed, and Cochrane Library), from 1994 to June 2022, to evaluate the outcomes in patients with abnormal uterine bleeding (AUB) undergoing EA using hysteroscopic and non-hysteroscopic techniques. Only scientific publications in English were included. Twelve articles on the current use of endometrial ablation were included. Data on patient symptoms, tools used for EA, primary outcomes, and adverse events were recorded. EA should be considered an effective and safe approach in the management of patients with abnormal uterine bleeding caused by benign pathology, in whom medical treatment has failed or is contraindicated. Due to the lack of evidence, it would be interesting to determine whether EA would also have a role in the treatment of women with premalignant lesions, avoiding invasive surgical procedures or medical treatment in those patients for whom hysterectomy or the use of hormonal treatment is contraindicated.

The Role of Genital Tract Microbiome in Fertility: A Systematic Review

The human microbiome plays a crucial role in determining the health status of every human being, and the microbiome of the genital tract can affect the fertility potential before and during assisted reproductive treatments (ARTs). This review aims to identify and appraise studies investigating the correlation of genital microbiome to infertility. Publications up to February 2021 were identified by searching the electronic databases PubMed/MEDLINE, Scopus and Embase and bibliographies. Only full-text original research articles written in English were considered eligible for analysis, whereas reviews, editorials, opinions or letters, case studies, conference papers, and abstracts were excluded. Twenty-six articles were identified. The oldest studies adopted the exclusive culture-based technique, while in recent years PCR and RNA sequencing based on 16S rRNA were the most used technique. Regardless of the anatomical site under investigation, the Lactobacillus-dominated flora seems to play a pivotal role in determining fertility, and in particular Lactobacillus crispatus showed a central role. Nonetheless, the presence of pathogens in the genital tract, such as Chlamydia trachomatis, Gardnerella vaginalis, Ureaplasma species, and Gram-negative stains microorganism, affected fertility also in case of asymptomatic bacterial vaginosis (BV). We failed to identify descriptive or comparative studies regarding tubal microbiome. The microbiome of the genital tract plays a pivotal role in fertility, also in case of ARTs. The standardization of the sampling methods and investigations approaches is warranted to stratify the fertility potential and its subsequent treatment. Prospective tubal microbiome studies are warranted.

Hystero-salpingo scintigraphy for fallopian tubal patency assessment: results from a prospective study

OBJECTIVE

To evaluate the diagnostic accuracy of a bygone method, hystero-salpingo-scintigraphy (HSSG), for tubal patency assessment of infertile women.

MATERIAL AND METHODS

Prospective cohort study involving women in the infertility workup at the University of Debrecen, Hungary. Seventy infertile patients were scheduled to either basic dynamic HSSG, post-purge dynamic HSSG, or post-purge dynamic HSSG followed by SPECT/CT for reducing tracer contamination. The primary endpoint was the evaluation of the diagnostic accuracy of HSSG for the three methods.

RESULTS

During the basic dynamic group, the examination yielded a sensitivity of 87.5%, with a specificity of 71.7%, while positive and negative predictive values were 31.8%, and 97.4% respectively. Using post purge dynamic HSSG, it resulted in a sensitivity of 87.5%, a specificity of 88.7%, a positive predictive value of 53.8%, and a negative predictive value of 97.9%. Adding SPECT/CT to post-purge dynamic HSSG increased diagnostic accuracy with 100% sensitivity and 88.7% specificity, while positive and negative predictive values were 57.1% and 100%, respectively.

CONCLUSION

HSSG is a non-invasive and well-tolerated technique for tubal patency. It could be used initially to predict tubal patency in case of infertility. Its diagnostic accuracy is higher when it is carried out by adding SPECT/CT to the post-purge dynamic method.

Hysteroscopy for Assessing Fallopian Tubal Obstruction: A Systematic Review and Diagnostic Test Accuracy Meta-analysis

OBJECTIVE

To assess the diagnostic accuracy of hysteroscopy compared with that of laparoscopic chromopertubation for the detection of fallopian tubal obstruction.

DATA SOURCES

An electronic search from inception to March 31, 2020, was performed in Medline, Scopus, EMBASE, and the Cochrane Central Register of Controlled Trials.

METHODS OF STUDY SELECTION

This diagnostic accuracy meta-analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Synthesizing Evidence from Diagnostic Accuracy Tests recommendations. A combination of the following Medical Subject Headings terms and keywords was included in the search strategy: "hysteroscopy[MeSH]," "tubal obstruction," "tubal patency," "tubal dysfunction," and "tubal blockage." Quality assessment of the included studies was conducted using the Quality Assessment Tool for Diagnostic Accuracy Studies-2 (University of Bristol, Bristol, United Kingdom). Publication bias was evaluated by means of the Deek funnel plot asymmetry test. The following outcomes were analyzed: diagnostic odds ratio, area under hierarchical summary receiver operating characteristic and area under receiver operating characteristic curve, sensitivity, specificity, and positive and negative likelihood ratios.

TABULATION, INTEGRATION, AND RESULTS

Six studies comparing hysteroscopy with laparoscopic chromopertubation were included in the meta-analysis. After pooling all the studies, the diagnostic odds ratio was 43. The evaluated area under receiver operating characteristic curve was 0.93, correlating with high diagnostic accuracy for the index test. Sensitivity and specificity were 88% and 85%, respectively. In addition, the positive and negative likelihood ratios were 5.88 and 0.16, respectively.

CONCLUSION

Hysteroscopic techniques are highly accurate and sensitive for detecting fallopian tubal obstruction. Interventional assessment enhances diagnostic accuracy compared with observational assessment, as does the office setting compared with the operating room. Additional studies, along with a refinement of the techniques, could facilitate the widespread use of hysteroscopic techniques for the detection of fallopian tube occlusion.

Single-Incision Mini-Sling for the Treatment of Female Stress Urinary Incontinence: Is it Actually Inferior to Transobturator Vaginal Tape and Tension-Free Vaginal Tape?

Objectives:

The aim of the study was to report the extended long-term results of the use of single-incision mini-sling (SIMS), tension-free vaginal tape (TVT), and transobturator tape (TOT) for the treatment of female stress urinary incontinence (SUI) at the Department of Gynecology and Obstetrics of the University Medical Center Ljubljana.

Materials and Methods:

Enrolled women were evaluated by Patient Global Impression of Severity (PGI-S), Patient Global Impression of Improvement (PGI-I), Sandvik severity scale, Urogenital Distress Inventory (UDI-6), Incontinence Impact Questionnaire (IIQ-7), and Incontinence Questionnaire-Urinary Incontinence (ICIQ-UI) Short Form and data about diagnosis, procedures, complications, reoperations, postoperative results, and satisfaction with procedure were recorded.

Results:

In analyzed group of patients (n = 357), 116 (32%) underwent SIMS procedure, 189 (53%) TOT, and 52 (15%) TVT. The SIMS, TOT, and TVT groups did not differ significantly from each other in PGI-S, PGI-I, Sandvik severity scale, UDI-6, IIQ-7, and ICIQ-UI Short Form or in postoperative complication rate. Repeat surgery was needed in 9.5% after SIMS, in 13.2% of TOT patients and in 23.1% of TVT patients (P = 0.194). Urinary retention occurred in 9.5% of the SIMS patients, in 9.5% of the TOT patients, and in 13.5% of the TVT patients (P = 0.682). Mesh erosion/inflammation occurred in 3.4% of the SIMS patients, in 6.3% of the TOT patients, and in 3.8% of the TVT patients (P = 0.485).

Conclusion:

The efficacy and safety of SIMS, TOT, and TVT in the surgical treatment of SUI are comparable. The choice of the technique should be based on the relative pros and cons of techniques and the surgeon's experience.
