Gestational diabetes mellitus is associated with in vivo platelet activation and platelet hyperreactivity.

BACKGROUND: Gestational diabetes mellitus is associated with obstetrical and long-term cardiovascular complications. Although platelet hyperresponsiveness in type-2 diabetes mellitus has been well characterized and has been shown to play a crucial role in cardiovascular complications, this aspect has been little studied in gestational diabetes mellitus. OBJECTIVE: We aimed to evaluate platelet reactivity, in vivo platelet activation, and endothelial function in gestational diabetes mellitus in comparison with normal pregnancy. STUDY DESIGN: This was a prospective, case-control study of 23 women with gestational diabetes mellitus and 23 healthy pregnant women who were studied at 26 to 28 and 34 to 36 weeks of gestation and at 8 weeks postpartum. Platelet reactivity and in vivo platelet activation, including light transmission aggregometry, PFA-100, platelet activation antigen expression, platelet adhesion under flow, platelet nitric oxide and reactive oxygen species production, and endothelial dysfunction markers, were assessed. RESULTS: The study of platelet function showed a condition of platelet hyperreactivity in cases with gestational diabetes mellitus when compared with healthy pregnant women at enrollment, which was further enhanced at the end of pregnancy and tended to decrease 2 months after delivery, although it still remained higher in gestational diabetes mellitus. In vivo platelet activation was also evident in gestational diabetes mellitus, especially at the end of pregnancy, in part persisting up to 8 weeks after delivery. Finally, women with gestational diabetes mellitus showed defective platelet nitric oxide production and endothelial dysfunction when compared with healthy pregnancies. CONCLUSION: Our data showed that gestational diabetes mellitus generates a condition of platelet hyperreactivity that in part persists up to 2 months after delivery. Impaired platelet sensitivity to nitric oxide and reduced platelet and endothelial nitric oxide production may contribute to the platelet hyperreactivity condition. Platelet hyperreactivity may play a role in the long-term cardiovascular complications of gestational diabetes mellitus women.

Biochemical and Anthropometric Parameters for the Early Recognition of the Intrauterine Growth Restriction and Preterm Neonates at Risk of Impaired Neurodevelopment.

BACKGROUND: S100B and Tau are implicated with both brain growth and injury. Their urinary levels in 30-to-40-day-old full-term, preterm, IUGR, and preterm-IUGR subjects were measured to investigate their possible relationship with future delayed neurodevelopment. METHODS: Values were related to the neuro-behavioral outcome at two years of age, as well as to brain volumes and urinary NGF assessed at the same postnatal time point. RESULTS: Using the Griffiths III test, cognitive and motor performances were determined to establish subgroups characterized by either normal or impaired neuro-behavior. The latter included preterm, IUGR, and preterm-IUGR individuals who exhibited significantly higher and lower S100B and Tau levels, respectively, along with markedly reduced cerebral volumes and urinary NGF, as previously demonstrated. Contrary to NGF, however, Tau and S100B displayed a weak correlation with brain volumes. CONCLUSIONS: Delayed cognitive and motor performances observed in two-year-old preterm and IUGR-born individuals were also found to be associated with anomalous urinary levels of S100B and Tau, assessed at 30-40 days of the postnatal period, and their changes did not correlate with brain growth. Thus, our data suggests that, in addition to cerebral volumes and NGF, urinary S100B and Tau can also be considered as valuable parameters for the early detection of future neurodevelopmental abnormalities.

Training in Diagnostic Hysteroscopy: The "Arbor Vitae" Method.

Background and Objectives: Diagnostic hysteroscopy is the gold standard in the diagnosis of intrauterine pathology and is becoming an essential tool in the daily practice of gynecology. Training programs for physicians are necessary to ensure adequate preparation and learning curve before approaching patients. The aim of this study was to describe the "Arbor Vitae" method for training in diagnostic hysteroscopy and to test its impact on the knowledge and skills of trainees using a customized questionnaire. Materials and Methods: A three-day hysteroscopy workshop combining theory and practical "hands on "sessions with dry and wet labs has been described. The aim of the course is to teach indications, instruments, the basic principles of the technique by which the procedure should be performed, and how to recognize and manage the pathologies that can be identified by diagnostic hysteroscopy. To test this training method and its impact on the knowledge and skills of the trainees, a customized 10-question questionnaire was administered before and after the course. Results: The questionnaire was administered to 34 participants. All trainees completed the questionnaire, and no missing responses were recorded. Regarding the characteristics of the participants, 76.5% had less than 1 year of experience in performing diagnostic hysteroscopy and 55.9% reported performing fewer than 15 procedures in their career. For 9 of the 10 questions embedded in the questionnaire, there was a significant improvement in the scores between pre- and post-course, demonstrating a perceived significant improvement in theoretical/practical skills by the trainees. Conclusions: The Arbor Vitae training model is a realistic and effective way to improve the theoretical and practical skills required to perform correct diagnostic hysteroscopy. This training model has great potential for novice practitioners to achieve an adequate level of proficiency before performing diagnostic hysteroscopy on live patients.

Urinary Cystatin-C, a marker to assess and monitor neonatal kidney maturation and function: validation in twins.

BACKGROUND: Nephrogenesis is a complex process of nephron formation and maturation that can be compromised by preterm delivery and intrauterine growth restriction. This study aimed to evaluate and compare urinary Cys-C levels with renal volume in a cohort of preterm and term twins, adequate for gestational age or intrauterine growth restricted, to investigate their values in different conditions of nephrogenesis. METHODS: The study was performed on twins at 30-40 days of postnatal corrected age: renal volumes were measured by 3D ultrasound technology and urine samples were analyzed for Cystatin-C. A follow-up was performed by Cystatin-C. RESULTS: Renal volumes in preterm and intrauterine growth-restricted twins showed values significantly lower than those observed in term twins and were inversely correlated to urinary Cystatin-C levels. During the follow-up, intrauterine growth-restricted twins showed amplified levels of urinary Cystatin-C; in contrast, invariable or decreased levels were observed in adequate for gestational age twins. CONCLUSIONS: Urinary Cystatin-C, evaluated when intrauterine/extrauterine nephrogenesis could be considered completed, concurrently with renal volume assessment can improve the identification of neonates with initial kidney impairment. Its potential value as a useful marker in monitoring physiological/pathological renal conditions could be considered, mainly for neonates at elevated risk of developing long-term renal diseases. IMPACT: Urinary Cys-C levels are inversely correlated to renal volumes and reflect nephrogenesis conditions. No data in literature are reported regarding: (a) the concurrent assessment of renal volumes and urinary levels of Cystatin-C in preterm and term twins with different conditions of gestational life, i.e., AGA and IUGR and (b) the follow-up of IUGR and preterm neonates using the urinary Cys-C determination. The variations of urinary Cys-C levels, observed in the follow-up of preterm and/or IUGR neonates, support the usefulness of monitoring those neonates with altered nephrogenesis, who are later at risk for renal impairment and for long-term renal diseases.

Risk factors for non-adherent retained placenta after vaginal delivery: a systematic review.

BACKGROUND: Retained placenta represents a cause of maternal morbidity and mortality affecting 0.5-3% of all vaginal deliveries. The unpredictability of this condition makes difficult to develop predictive and preventive strategies to apply in clinical practice. This analysis collected and analyzed all known risk factors related to this obstetric complication. METHODS: A systematic literature review for all original research articles published between 1990 and 2020 was performed. Observational studies about retained placenta risk factors published in English language were considered eligible. Conference abstracts, untraceable articles and studies focused on morbidly adherent placenta were excluded. The included articles were screened to identify study design, number of enrolled patients and retained placenta risk factors investigated. All stages of the revision followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. RESULTS: Thirty-five studies met the inclusion criteria. The reported retained placenta prevalence ranged from 0.5 to 4.8%. Maternal age, previous cesarean sections, previous dilation and curettage, previous retained placenta, labor induction, resulted as the most recurrent, independent risk factors for retained placenta. Previous estro-progestins therapy, morphological placental features (weight, shape, insertion of umbilical cord, implantation site), endometriosis, Assisted Reproductive Technologies, Apgar score are fascinating new proposal risk factors. CONCLUSIONS: Old and new data are not enough robust to draw firm conclusions. Prospective and well-designed studies, based on a well agreed internationally retained placenta definition, are needed in order to clarify this potential dramatic and life-threatening condition.

Antepartum Distress during COVID-19 Pandemic: an Observational Study.

BACKGROUND: The present study investigates the impact of the Coronavirus diseases 2019 (Covid-19) pandemic on the subjective experience of pregnant women, as well as the impact of the pandemic on this population in terms of psychopathological correlates. SUBJECTS AND METHODS: Pregnant women referring to the Section of Obstetrics and Gynecology of the General Hospital of Perugia, Italy, were recruited from 1st May, 2021 to 15th June, 2021. Socio-demographic and clinical data was collected, as well as information regarding the Covid-19 pandemic impact on the subjective experience of pregnancy. Psychopathology was evaluated by means of the State-Trait Anxiety Inventory Form Y (STAI-Y), the Symptom Checklist-90 (SCL-90) and the Prenatal Distress Measure (Pre-DM). Descriptive analyses were performed. Significant associations between distress symptoms and the collected sociodemographic and clinical variables were assessed by using the Pearson correlation (p<0.05). RESULTS: 25 women were included in the study. Among these, 18 (72%) reported that the Covid-19 pandemic negatively impacted their experience of pregnancy. Were detected an average Pre-DM total score of 7.28±4.33 and an average state anxiety scale value of 35.56±9.21 and an average trait anxiety scale value of 34.04±7.44 at the STAI-Y. A global severity index > 1 at SCL-90 was detected in 8.3% of the sample. CONCLUSIONS: The identification of antepartum distress and the early treatment of perinatal psychopathology represent a priority during the Covid-19 pandemic era.

The Technique of Vaginal Septum as Uterine Septum: A New Approach for the Hysteroscopic Treatment of Vaginal Septum.

STUDY OBJECTIVE: To evaluate the outcomes of a new hysteroscopic technique for the treatment of a longitudinal vaginal septum. DESIGN: A retrospective study. SETTING: Arbor Vitae Center for Endoscopic Gynecology, Rome, Italy. PATIENTS: Thirty women who underwent hysteroscopic treatment for a vaginal septum. INTERVENTION: All enrolled patients underwent pelvic examination, hysteroscopy, and 2-dimensional ultrasound. In case of a diagnosis of a partial or complete uterine septum, magnetic resonance imaging or 3-dimensional ultrasound were performed, and surgical procedures were performed after diagnostic laparoscopy was used to better visualize the uterine fundus. All patients were treated with the technique using vaginal septum as uterine septum or the same methodology applied for a uterine septum. MEASUREMENTS AND MAIN RESULTS: The procedure was successfully accomplished in all patients, and longitudinal vaginal septa were totally resected. There were no perioperative complications, and in only 1 case, vaginal bleeding occurred because of an erroneous identification of the excision line that was easily remedied with coagulation by resectoscope. Dyspareunia has improved or completely disappeared in all patients. CONCLUSION: The technique of vaginal septum as uterine septum for the resectoscope of a longitudinal vaginal septum appears to be safe and effective with good outcomes, even in terms of dyspareunia.

Effects of Sodium Hyaluronate on Symptoms and Quality of Life in Women Affected by Pregnancy Rhinitis: A Pilot Study.

AIMS: To investigate sodium hyaluronate (SH) efficacy in the treatment of pregnancy rhinitis. METHODS: A single-center, prospective, open-label, 2 parallel-group study was carried out. Pregnant women affected by pregnancy rhinitis were randomly assigned to 1 of 2 groups: Group A was treated with SH, while Group B did not receive any treatment. Pregnancy rhinitis symptoms and quality of life (QOL) during pregnancy were investigated by administering a questionnaire and carrying out an otorhinolaryngoiatric visit. RESULTS: A significant reduction in the intensity of headache, snoring and insomnia in the Group A compared to the Group B were demonstrated. In the Group A, a significant lower presence of amount of secretions (Group A 0.88, 95% CI 0.57-1.18 vs. Group B 2.00, 95% CI 1.69-2.31, p < 0.001), turbinate hypertrophy (Group A 1.70, 95% CI 1.46-1.94 vs. Group B 2.53, 95% CI 2.29-2.77, p < 0.001), and mucosal congestion/hyperemia (Group A 1.41, 95% CI 1.14-1.68 vs. Group B 2.26, 95% CI 1.99-2.53, p < 0.001) was observed. No adverse events were reported in patients treated with SH. CONCLUSIONS: SH is a safe and effective therapeutic alternative for the treatment of pregnancy rhinitis symptoms, improving patients' QOL.

Intraoperative Effect of Preoperative Gonadotropin-Releasing Hormone Analogue Administration in Women Undergoing Cold Loop Hysteroscopic Myomectomy: A Randomized Controlled Trial.

STUDY OBJECTIVE: To evaluate the intraoperative effects of gonadotropin-releasing hormone (GnRH) analogue pretreatment in patients undergoing cold loop hysteroscopic myomectomy. DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTING: Arbor Vitae Center for Endoscopic Gynecology, Rome, Italy. PATIENTS: A total of 99 patients were randomized and subsequently allocated to the GnRH analogue group or to the nonpharmacologic treatment control group. Fifteen patients were lost after allocation, and 42 patients per group underwent hysteroscopic myomectomy. INTERVENTIONS: Cold loop hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: The control group accomplished the treatment in a 1-step procedure more frequently than the GnRH analogue group (92.85% and 73.8% of cases, respectively; p = .040). The completion of the treatment was more unlikely in case of G2 myomas (p = .006), whereas no differences were recorded for G1 and G0 myomas. The multivariate analysis showed a significant correlation between the multiple-step treatment and the use of GnRH analogue (odds ratio, 5.365; 95% confidence interval [CI], 1.018-28.284; p = .048), grading (odds ratio, 4.503; 95% CI, 1.049-19.329; p = .043), and size of myomas (odds ratio, 1.128; 95% CI, 1.026-1.239; p = .013). CONCLUSIONS: Preoperative GnRH analogue administration did not facilitate the completion of cold loop hysteroscopic myomectomy in a single surgical procedure in G2 myomas and was correlated with a longer duration of the surgery. No significant benefits were found for G0 and G1 myomas. (ClinicalTrials.gov: NCT01873378.).

Epigenetic and genetic landscape of uterine leiomyomas: a current view over a common gynecological disease.

PURPOSE: Despite the numerous studies on the factors involved in the genesis and growth of uterine leiomyomas, the pathogenesis of these tumors remains unknown. Intrinsic abnormalities of the myometrium, abnormal myometrial receptors for estrogen, and hormonal changes or altered responses to ischemic damage during the menstrual period may be responsible for the initiation of (epi)genetic changes found in these tumors. Considering these elements, we aimed to offer an overview about epigenetic and genetic landscape of uterine leiomyomas. METHODS: Narrative overview, synthesizing the findings of literature retrieved from searches of computerized databases. RESULTS: Several studies showed that leiomyomas have a monoclonal origin. Accumulating evidence converges on the risk factors and mechanisms of tumorigenesis: the translocation t (12;14) and deletion of 7q were found in the highest percentages of recurrence; dysregulation of the HMGA2 gene has been mapped within the critical 12q14-q15 locus. Estrogen and progesterone are recognized as promoters of tumor growth, and the potential role of environmental estrogens has been poorly explored. The growth factors with mitogenic activity, such as transforming growth factor-ß3, fibroblast growth factor, epidermal growth factor, and insulin-like growth factor-I are elevated in fibroids and may have a role as effectors of the tumor promotion. CONCLUSION: The new clues on genetics and epigenetics, as well as about the growth factors that control normal and pathological myometrial cellular biology may be of great help for the development of new effective and less invasive therapeutic strategies in the near future.

Bi-parametric magnetic resonance imaging applied to obstetrics.

Foetal magnetic resonance imaging (MRI) plays an increasingly important role in the diagnosis of foetal abnormalities. Over the years, we have successfully applied bi-parametric MRI (bp-MRI) to the following obstetric conditions: (1) neurologic vascular diseases; (2) assessment of lung parenchyma maturation; (3) renal pathologies, such as polycystic kidney, suspected renal infarction, unilateral or bilateral renal agenesis; (4) placental pathologies, as twin-twin transfusion syndrome or placenta accreta; (5) benignant and malignant congenital tumours or cysts of the liver, such as haemangioendothelioma, hepatoblastoma or metastatic neuroblastoma, of the kidney (e.g. mesoblastic nephroma) and of the retroperitoneum, such as teratoma. The information derived from bp-MRI, and concerned with water motions in different tissues, improved the morphologic details provided by conventional foetal MRI. It has the potential to increase the value of MRI in the assessment of a wide range of foetal pathologies, particularly in renal diseases, allowing an adequate management decision and therapy.

Endovascular management of massive post-partum haemorrhage in abnormal placental implantation deliveries.

OBJECTIVES: To retrospectively evaluate safety and efficacy of pelvic artery embolisation (PAE) in post-partum haemorrhage (PPH) in abnormal placental implantation (API) deliveries. METHODS: From January 2009 to November 2013, 12 patients with API and intractable intraoperative PPH underwent PAE after caesarean delivery to control a haemorrhage (in four of these cases after hysterectomy). Arterial access was obtained prior to the delivery; PAE was performed in the obstetrics operating room by an interventional radiologist that was present with an interventional radiology (IR) team during the delivery. RESULTS: PAE was successful in preventing bleeding and avoid hysterectomy in four cases (group A). Uterine atony and disseminated intravascular coagulation caused failure of PAE requiring hysterectomy in four patients (group B). PAE prevented bleeding post-hysterectomy in the remaining four cases (group C). Technical success (cessation of contrast extravasation on angiography or occlusion of the selected artery) was 100 %. Maternal and foetal mortality and morbidity were 0 %. CONCLUSIONS: PAE is a minimal invasive technique that may help to prevent hysterectomy and control PPH in API pregnancies without complications. Embolisation should be performed on an emergency basis. For such cases, an IR team on standby in the obstetrics theatre may be useful to prevent hysterectomy, blood loss and limit morbidity. KEY POINTS: • Endovascular treatment is a validated technique in post-partum haemorrhage. • Abnormal placental implantation is a risk factor for post-partum haemorrhage. • We propose an interventional radiologist standby in the delivery room.

Tubal pregnancy after clomiphene treatment: are you sure is not bilateral?

The estimated prevalence of ectopic pregnancy (EP) is 1-2% worldwide. Bilateral tubal pregnancies represent the rarest form of heterotopic pregnancy, and spontaneously conceived are extremely unusual, as many cases are derived from assisted reproductive techniques. We describe a case of bilateral tubal pregnancy after clomiphene therapy and sexual intercourse in which the second EP was not contemporarily revealed.

Results from the International Consensus Conference on myo-inositol and D-chiro-inositol in Obstetrics and Gynecology--assisted reproduction technology.

A substantial body of research on mammalian gametogenesis and human reproduction has recently investigated the effect of myo-inositol (MyoIns) on oocyte and sperm cell quality, due to its possible application to medically assisted reproduction. With a growing number of both clinical and basic research papers, the meaning of several observations now needs to be interpreted under a solid and rigorous physiological framework. The 2013 Florence International Consensus Conference on Myo- and D-chiro-inositol in obstetrics and gynecology has answered a number of research questions concerning the use of the two stereoisomers in assisted reproductive technologies. Available clinical trials and studies on the physiological and pharmacological effects of these molecules have been surveyed. Specifically, the physiological involvement of MyoIns in oocyte maturation and sperm cell functions has been discussed, providing an answer to the following questions: (1) Are inositols physiologically involved in oocyte maturation? (2) Are inositols involved in the physiology of spermatozoa function? (3) Is treatment with inositols helpful within assisted reproduction technology cycles? (4) Are there any differences in clinical efficacy between MyoIns and D-chiro-inositol? The conclusions of this Conference, drawn depending on expert panel opinions and shared with all the participants, are summarized in this review paper.

Is Cold Loop Hysteroscopic Myomectomy a Safe and Effective Technique for the Treatment of Submucous Myomas With Intramural Development? A Series of 1434 Surgical Procedures.

STUDY OBJECTIVE: To assess the safety and efficacy of cold loop hysteroscopic myomectomy in a large series of cases. DESIGN: Retrospective study (Canadian Task Force Classification III). SETTING: Arbor Vitae Center for Endoscopic Gynecology, Rome, Italy. PATIENTS: A total of 1215 patients with 1 or more G1-G2 submucous myomas. INTERVENTION: Cold loop hysteroscopic myomectomy. MEASUREMENT AND MAIN RESULTS: A total of 1690 myomas were removed. A minimum of 1 to a maximum of 5 fibroids for each surgical procedure were totally removed. Out of 1215 patients, 1017 (83.7%) were treated with a single surgical procedure. Twelve intraoperative complications occurred (0.84%). No cases of uterine perforation with the thermal loop or clinical intravasation syndrome were reported. CONCLUSION: Cold loop hysteroscopic myomectomy seems to represent a safe and effective procedure for the removal of submucous myomas with intramural development, while at the same time respecting the anatomic and functional integrity of the myometrium. The use of a cold loop in resectoscopic myomectomy is associated with a low rate of minor intraoperative complications and an absence of major complications. This could be of primary relevance with a view to fertility and future pregnancies.

Is 'cold loop' hysteroscopic myomectomy a better option for reproduction in women with diffuse uterine leiomyomatosis? A case report of successful repeated pregnancies.

Diffuse uterine leiomyomatosis (DUL) is a rare clinical entity with important reproductive consequences. To date, only four pregnancies have been reported after hysteroscopic myomectomy. Here we describe the case of a 28-year-old infertile woman with diffuse uterine leiomyomatosis, who presented infertility and metrorrhagia lasting for 2 years. A countless number of subserous, intramural and submucous myomas were ultrasonographically revealed. Diagnostic hysteroscopy described a uterine cavity completely subverted by the presence of myomas. A two-step 'cold loop' hysteroscopic myomectomy was performed following the technique previously described. One month after the treatment, there were no submucous myomas. A regular uterine cavity free of synechiae was endoscopically confirmed. After the treatment, the patient carried to term three consecutive, uneventful pregnancies. This is the first report of repeated successful pregnancies following the 'cold loop' hysteroscopic technique in DUL. We believe that 'cold loop' resectoscopic myomectomy may provide new advantageous perspectives for women with DUL seeking pregnancy.

Isthmocele, not cesarean section per se, reduces in vitro fertilization success: a systematic review and meta-analysis of over 10,000 embryo transfer cycles.

IMPORTANCE: Previous reviews have shown that a history of cesarean section (CS) is associated with a worse in vitro fertilization (IVF) prognosis. To date, whether the decline in the IVF chances of success should be attributed to the CS procedure itself or to the presence of isthmocele remains to be clarified. OBJECTIVE: To summarize the available evidence regarding the impact of isthmocele on IVF outcomes. DATA SOURCES: Electronic databases and clinical registers were searched until May 30, 2023. STUDY SELECTION AND SYNTHESIS: Observational studies were included if they assessed the effect of isthmocele on IVF outcomes. Comparators were women with isthmocele and women without isthmocele with a previous CS or vaginal delivery. Study quality was assessed using the modified Newcastle-Ottawa Scale. MAIN OUTCOMES: The primary outcome was the live birth rate (LBR). The effect measures were expressed as adjusted odds ratios (aORs) and unadjusted odds ratios (uORs) with 95% confidence intervals (95% CIs). The body of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation working group methodology. RESULTS: Eight studies (n = 10,873 patients) were included in the analysis. Women with isthmocele showed a lower LBR than both women with a previous CS without isthmocele (aOR, 0.62; 95% CI, 0.53-0.72) and those with a history of vaginal delivery (aOR, 0.55; 95% CI, 0.42-0.71). The LBRs in women with a previous CS without isthmocele and those with a history of vaginal delivery were similar (aOR, 0.74; 95% CI, 0.47-1.15). Subgroup analysis suggested a negative effect of the intracavitary fluid (ICF) in women with isthmocele on the LBR (uOR, 0.36; 95% CI, 0.18-0.75), whereas the LBRs in women without ICF and those without isthmocele were similar (uOR, 0.94; 95% CI, 0.61-1.45). CONCLUSION AND RELEVANCE: We found moderate quality of evidence (Grading of Recommendations Assessment, Development and Evaluation grade 3/4) supporting a negative impact of isthmocele, but not of CS per se, on the LBR in women undergoing IVF. The adverse effect of isthmocele on IVF outcomes appears to be worsened by ICF accumulation before embryo transfer. CLINICAL TRIAL REGISTRATION NUMBER: CRD42023418266.

Efficacy, safety, and feasibility of the treatment of intrauterine pathologies with the mini-resectoscope: A systematic review.

BACKGROUND: Hysteroscopy represents the gold standard for the diagnosis and treatment of intrauterine pathologies. The advent of the mini-resectoscope heralded a new era in intrauterine surgery, both in inpatient and outpatient settings. OBJECTIVES: To evaluate the effectiveness, safety, and feasibility of the mini-resectoscope for the treatment of intrauterine pathologies. SEARCH STRATEGY: Electronic databases were searched for English-language trials describing surgical procedures for uterine pathologies performed with a mini-resectoscope until 30 April 2023. SELECTION CRITERIA: Retrospective or prospective original studies reporting the treatment of uterine pathologies with mini-resectoscope were deemed eligible for the inclusion. DATA COLLECTION AND ANALYSIS: Data about study features, characteristics of included populations, surgical procedures, complications, and results/outcomes were collected. RESULTS: Seven papers that met the inclusion criteria were included in this systematic review. Quantitative analysis was not possible due to data heterogeneity. A descriptive synthesis of the results was provided accordingly to the pathology hysteroscopically removed/corrected: polyps and myomas, uterine septum, intrauterine synechiae, and isthmocele. CONCLUSIONS: The mini-resectoscope is poised to play a leading role in hysteroscopic surgery for many pathologies, both in inpatient and outpatient settings. Since some applications of the mini-resectoscope have not yet been thoroughly investigated, future studies should address current knowledge gaps, designing high-quality comparative trials on specific applications.
