Comparison of laparoscopic sacrocolpopexy with vaginal reconstructive procedures and abdominal sacrocolpopexy for the surgical management of vaginal vault prolapse: a systematic review and meta-analysis.

Introduction: Vaginal vault prolapse, also known as apical prolapse, is a distressing condition that may affect women following hysterectomy, necessitating surgical intervention when conservative measures prove ineffective. The surgical management of apical compartment prolapse includes procedures such as laparoscopic sacrocolpopexy (LSCP), abdominal sacrocolpopexy (ASCP) or vaginal reconstructive procedures (VRP). This systematic review and meta-analysis aims to compare the outcomes of these interventions. Methods: A comprehensive search of electronic databases was conducted to identify eligible studies. Fourteen studies comprising a total of 1,289 women were included. The selected studies were analyzed to evaluate outcomes such as duration of surgery, length of hospital stay, blood loss, complication rates, and patient satisfaction. Results: LSCP did not demonstrate significant advantages over VRP in terms of perioperative or long-term outcomes. However, when compared to ASCP, LSCP showed shorter hospital stay, reduced blood loss, decreased postoperative pain, and lower rates of ileus. Discussion: This systematic review contributes to evidence-based decision-making for the surgical treatment of vaginal vault prolapse. While LSCP did not exhibit substantial benefits over VRP, it emerged as a preferable option compared to ASCP due to shorter hospital stays and reduced postoperative complications. The findings from this study provide valuable insights for clinicians and patients in selecting the most appropriate surgical approach for vaginal vault prolapse. However, future research should focus on long-term follow-ups, standardizing outcomes, and outcome measures, and evaluating cost-effectiveness to further enhance clinical practice.

Maternal and neonatal outcomes associated with delivery techniques for impacted fetal head at cesarean section: a systematic review and meta-analysis.

OBJECTIVES: Late first-stage or second-stage cesarean section is commonly associated with fetal head impaction, leading to maternal and neonatal complications. This situation requires safe delivery techniques, but the optimal management remains controversial. The aim of this meta-analysis was to compare maternal and neonatal outcomes associated with delivery techniques via cesarean section. METHODS: An electronic search of three databases, from inception to June 2021, was conducted. Cohort and randomised comparative studies on maternal and neonatal outcomes associated with techniques to deliver an impacted fetal head during cesarean section were included. The methodological quality of the primary studies was assessed. Review Manager 5.4 was used for statistical analyses. RESULTS: Nineteen articles, including 2,345 women were analyzed. Three fetal extraction techniques were identified. Meta-analyses showed that the "pull" technique carries lower risks as compared to the "push" technique and the "Patwardhan" technique is safer compared to the "push" or the "push and pull" technique. CONCLUSIONS: In the absence of robust evidence to support the use of a specific technique, the choice of the obstetrician should be based on best available evidence. Our study suggests that the "pull", as well as the "Patwardhan" technique represent safe options to deliver an impacted fetal head.

Ultrasonography in the Differentiation of Endometriomas from Hemorrhagic Ovarian Cysts: The Role of Texture Analysis.

The ultrasonographic (US) features of endometriomas and hemorrhagic ovarian cysts (HOCs) are often overlapping. With the emergence of new computer-aided diagnosis techniques, this is the first study to investigate whether texture analysis (TA) could improve the discrimination between the two lesions in comparison with classic US evaluation. Fifty-six ovarian cysts (endometriomas, 30; HOCs, 26) were retrospectively included. Four classic US features of endometriomas (low-level internal echoes, perceptible walls, no solid components, and less than five locules) and 275 texture parameters were assessed for every lesion, and the ability to identify endometriomas was evaluated through univariate, multivariate, and receiver operating characteristics analyses. The sensitivity (Se) and specificity (Sp) were calculated with 95% confidence intervals (CIs). The texture model, consisting of seven independent predictors (five variations of difference of variance, image contrast, and the 10th percentile; 100% Se and 100% Sp), was able to outperform the ultrasound model composed of three independent features (low-level internal echoes, perceptible walls, and less than five locules; 74.19% Se and 84.62% Sp) in the diagnosis of endometriomas. The TA showed statistically significant differences between the groups and high diagnostic value, but it remains unclear if the textures reflect the intrinsic histological characteristics of the two lesions.

Computer Tomography in the Diagnosis of Ovarian Cysts: The Role of Fluid Attenuation Values.

Pathological analysis of ovarian cysts shows specific fluid characteristics that cannot be standardly evaluated on computer tomography (CT) examinations. This study aimed to assess the ovarian cysts' fluid attenuation values on the native (Np), arterial (Ap), and venous (Vp) contrast phases of seventy patients with ovarian cysts who underwent CT examinations and were retrospectively included in this study. Patients were divided according to their final diagnosis into the benign group (n = 32) and malignant group (n = 38; of which 27 were primary and 11 were secondary lesions). Two radiologists measured the fluid attenuation values on each contrast phase, and the average values were used to discriminate between benign and malignant groups and primary tumors and metastases via univariate, multivariate, multiple regression, and receiver operating characteristics analyses. The Ap densities (p = 0.0002) were independently associated with malignant cysts. Based on the densities measured on all three phases, neoplastic lesions could be diagnosed with 89.47% sensitivity and 62.5% specificity. The Np densities (p = 0.0005) were able to identify metastases with 90.91% sensitivity and 70.37% specificity, while the combined densities of all three phases diagnosed secondary lesions with 72.73% sensitivity and 92.59% specificity. The ovarian cysts' fluid densities could function as an adjuvant criterion to the classic CT evaluation of ovarian cysts.

Differentiation of Endometriomas from Ovarian Hemorrhagic Cysts at Magnetic Resonance: The Role of Texture Analysis.

Background and Objectives: To assess ovarian cysts with texture analysis (TA) in magnetic resonance (MRI) images for establishing a differentiation criterion for endometriomas and functional hemorrhagic cysts (HCs) that could potentially outperform their classic MRI diagnostic features. Materials and Methods: Forty-three patients with known ovarian cysts who underwent MRI were retrospectively included (endometriomas, n = 29; HCs, n = 14). TA was performed using dedicated software based on T2-weighted images, by incorporating the whole lesions in a three-dimensional region of interest. The most discriminative texture features were highlighted by three selection methods (Fisher, probability of classification error and average correlation coefficients, and mutual information). The absolute values of these parameters were compared through univariate, multivariate, and receiver operating characteristic analyses. The ability of the two classic diagnostic signs ("T2 shading" and "T2 dark spots") to diagnose endometriomas was assessed by quantifying their sensitivity (Se) and specificity (Sp), following their conventional assessment on T1-and T2-weighted images by two radiologists. Results: The diagnostic power of the one texture parameter that was an independent predictor of endometriomas (entropy, 75% Se and 100% Sp) and of the predictive model composed of all parameters that showed statistically significant results at the univariate analysis (100% Se, 100% Sp) outperformed the ones shown by the classic MRI endometrioma features ("T2 shading", 75.86% Se and 35.71% Sp; "T2 dark spots", 55.17% Se and 64.29% Sp). Conclusion: Whole-lesion MRI TA has the potential to offer a superior discrimination criterion between endometriomas and HCs compared to the classic evaluation of the two lesions' MRI signal behaviors.

Transperineal Ultrasound Assessment of a Cystocele's Impact on the Bladder Neck Mobility in Women with Stress Urinary Incontinence.

Background and objectives: As pelvic floor disorders are often difficult to assess thoroughly based on clinical examination alone, the use of imaging as a complementary technique is helpful. This study's aim was to investigate by transperineal ultrasound (US) if there was any significant difference in the mobility of the bladder neck in women with stress urinary incontinence (SUI) without a cystocele and in those with SUI and an associated cystocele. The study also investigated whether the number of vaginal births and/or the heaviest newborn's birth weight was correlated with the bladder neck mobility. Materials and Methods: A total of 71 women suffering from SUI were included in the study and divided into two groups based on the presence of a cystocele. Their bladder neck mobility was evaluated by transperineal US, calculating the distance from the inferior margin of the symphysis pubis to the bladder neck (SPBN), and the dorsocaudal linear movement (DLM), term used to illustrate the displacement of the bladder neck by subtracting rest and Valsalva values. GraphPad Prism 8 was used for statistical analysis. Results: Within both study groups, the SPBN values were significantly higher and the DLM values were significantly lower at rest as compared to Valsalva maneuver (p < 0.05). No significant difference between the groups regarding SPBN and DLM values at rest, Valsalva, or subtraction was demonstrated. A significant positive correlation was found between the bladder neck mobility and the heaviest newborn's birth weight, regardless of the presence of a cystocele (p = 0.042). Conclusions: The presence of a cystocele had no significant impact on the bladder neck mobility measurements in patients with SUI. The heaviest newborn's birth weight positively correlated with bladder neck hypermobility, as quantified by SPBN.

Ultrasound Probe Pressure on the Maternal Abdominal Wall and the Effect on Fetal Middle Cerebral Artery Doppler Indices.

Background and objectives: Doppler ultrasound of umbilical and fetal vessels is useful for monitoring fetal well-being, fetal anemia, intrauterine growth retardation, and other perinatal outcomes. The adverse perinatal outcome and circulatory changes can be reflected in fetal Doppler studies. The aim of this study was to evaluate the effect of increased pressure exerted on the maternal abdominal wall during routine ultrasound on the middle cerebral artery (MCA), resistance index (RI), pulsatility index (PI), and peak systolic velocity (PSV). Materials and Methods: A prospective study was conducted, in which we included 40 pregnant women between 24 + 0 and 41 + 3 gestational weeks (GW), with singleton pregnancies, without any associated pathologies, undergoing routine US examination. We recorded the flow velocity waveforms in the MCA, and we measured the RI, PI, PSV, and the applied pressure on to the maternal abdominal wall-needed for a proper evaluation of MCA. We then repeated the same measurements at two different higher pressure levels, at the same time having a proper image of the targeted vessel. Results: We found significant differences for the PI and RI levels with an increase in abdominal pressure (median PI 1.46, 1.58, and 1.92, respectively; median RI 0.74, 0.78, and 0.85, respectively; p < 0.05), for both PI and RI. At the same time, we found no significant differences for PSV in the studied group in relationship with increase in abdominal pressure (median PSV 39.56, 40.10, and 39.70, respectively; p > 0.05). Conclusions: The applied abdominal pressure by the examiner's hand, during routine US scan in pregnancy, can modify the MCA parameters of blood flow resistance (PI and RI) when measured by Doppler US, thus influencing the diagnostic accuracy in a series of pregnancy associated pathologies, such as chronic fetal distress (CFD) or intrauterine growth restriction (IUGR).

Endometriosis-associated changes in serum levels of interferons and chemokines.

BACKGROUND/AIM: The aim of the study was to evaluate the serum concentration of main chemokines and interferons in patients with diagnosed endometriosis. MATERIALS AND METHODS: A total of 160 women were divided in two study groups (group 1 - endometriosis; group 2 - healthy women). Serum levels of IFN-α, IFN-γ, MCP-1, MIP-1α, MIP-1ß, RANTES, eotaxin, IL-8, MIG, IP-10, and IL-17A were measured with Human Multiplex Cytokine Panels. Results. Serum levels of IFN-γ, MCP-1, and IL-8 were significantly higher (mean 14.03, 57.24, and 534.24, respectively, compared to 0.58, 20.51, and 259.82, respectively), and serum levels of IP-10 and eotaxin were significantly lower in women with endometriosis compared to the controls (mean 1.15 and 1.01, respectively, compared to 3.90 and 3.22, respectively). Conclusions. According to our results women with endometriosis have elevated levels IFN-γ, MCP-1, and IL-8, and lower serum levels of IP-10 and eotaxin, indicating unbalanced immune activity in endometriosis.
