Initial experience of ureteric visualization using methylene blue during laparoscopy for gynecological surgery.

Objectives: Iatrogenic ureteral injury is a severe surgical complication, with a highest incidence of 1.5% in gynecological surgeries. The purpose of this report is to document our initial experience with using methylene blue (MB) to label the ureter in gynecological laparoscopic surgeries and to explore its effectiveness and safety. This is also a novel description of simultaneously visualizing ureteral MB fluorescence and sentinel lymph nodes (SLN's) Indocyanine Green (ICG) fluorescence using the same camera. Methods: This study included patients undergoing gynecological laparoscopic surgeries, with the same surgeon performing all cases. During the early stages of each surgery, rapid intravenous infusion of MB was administered. For cases requiring SLN imaging, we also injected ICG solution into the cervix. Assessment of the included cases was conducted both intraoperatively and postoperatively. The group that had MB fluorescence (Group A) was compared to a control group that did not have it (Group B). Results: A total of 25 patients (Group A) received MB during surgery, demonstrating 45 ureters clearly, with an imaging success rate of 90%. Continuous and clearer fluorescence imaging was achieved in cases with ureteral hydronephrosis. In most patients, ureteral fluorescence was visible 15-20 min after intravenous infusion of MB, and 64% still exhibited fluorescence at the end of the surgery. In patients who had both ICG and MB, dual fluorescence imaging was achieved clearly. Among the included cases, there were no iatrogenic ureteral injuries (0%), which we observed to be lower than in patients who did not receive MB (1.3%). The rate of adverse events was similar in both groups. Conclusion: Using MB fluorescence is an effective and safe method of visualizing the ureters during gynecological surgeries, and can diminish iatrogenic ureteral injury without increased associated adverse events. It therefore may offer promising prospects for clinical application.

Transvaginal morcellation within an enclosed bag in gynecological surgeries: a comprehensive systematic review and analysis of safety, efficacy, and outcomes.

PURPOSE: This systematic review aims to comprehensively assess the safety and efficacy of transvaginal morcellation within an enclosed bag in gynecological surgeries, with a focus on its benefits, potential risks, and recommendations for its use. METHODS: We conducted a comprehensive search of Epistemonikos, Web of Science, Medline (PubMed), Scopus, and Cochrane databases for studies on transvaginal contained morcellation in adult patients undergoing gynecological surgeries. The review included 22 studies that met the inclusion criteria, encompassing diverse surgical procedures, patient profiles, and outcomes. These studies were thoroughly reviewed and analyzed to assess the safety and efficacy of the morcellation technique. RESULTS: Key findings from the selected studies indicate that transvaginal morcellation within an enclosed bag offers several advantages in gynecological surgeries, including reduced invasiveness, shorter operative times, and minimal blood loss when compared to conventional methods. The risk of tumor recurrence or dissemination appears to be low when appropriate precautions are taken, emphasizing the technique's safety, especially when performed by experienced surgical teams. While some studies reported complications, these were generally not directly associated with the morcellation technique. CONCLUSION: Transvaginal morcellation within an enclosed bag demonstrates potential as a safe and effective option for gynecological surgeries. The technique offers the benefits of minimally invasive procedures, including reduced bleeding, shorter recovery times, and improved cosmetic outcomes. This review also highlights the need for standardization in study methodologies and reporting, as the heterogeneity in outcomes across the selected studies poses challenges in drawing definitive conclusions.

Influence of humanistic care on negative emotions, nursing quality, and patient satisfaction in outpatient gynecological surgery.

OBJECTIVE: To explore the impact of humanistic care on negative emotions, nursing quality and patient satisfaction among women undergoing outpatient gynecological surgery. METHODS: This retrospective study involved 108 patients who underwent outpatient gynecological surgery at the Second Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine between August 2022 and August 2023. The patients were divided into two groups: 51 patients received routine care (control group) and 57 received humanistic care (experimental group). Data collected included vital signs (heart rate [HR] and systolic/diastolic blood pressure [SBP/DBP]), pain levels (Visual Analogue Scale [VAS] scores at 12 and 24 hours postoperative), negative emotions (Self-rating Anxiety/Depression Scale [SAS/SDS]), comfort (Kolcaba's General Comfort Questionnaire [GCQ]), sexual functioning (Brief Index of Sexual Functioning for Women), nursing quality (errors, defects, and complaints) and patient satisfaction. RESULTS: Intraoperative SBP, DBP, along with HR, were significantly lower in the experimental group compared to the control group (all P<0.05). Postoperative pain levels at both 12 and 24 hours were also significantly reduced in the experimental group (both P<0.01). Furthermore, the experimental group demonstrated significant reductions in SAS and SDS scores and higher GCQ scores across physical, psychospiritual, environmental, and sociocultural dimensions (all P<0.05). There were no significant differences between the groups in terms of sexual desire, activity, and satisfaction (all P>0.05). Nursing quality was significantly better (P=0.029) and patient satisfaction with nursing care was higher (P=0.015) in the experimental group. CONCLUSIONS: Humanistic care significantly reduces negative emotions and enhances comfort, nursing quality, and patient satisfaction in women undergoing outpatient gynecological surgery. This approach does not affect sexual functioning indicators but offers substantial improvements in overall patient care and outcomes. Its high value for clinical promotion underscores its potential as a transformative approach in outpatient gynecological settings.

Metastatic benign leiomyoma: A case report of an uncommon presentation.

Uterine leiomyoma is a benign tumor of myometrial tissue which usually affects women of reproductive age. Its prevalence increases with age and has a peak incidence at the age of 40. Metastasizing leiomyomas are dense connective tissue and smooth myometrial muscle cells tumors located outside the uterus. We present the case report of a 55-year-old female referred to investigate pulmonary nodules with the diagnosis of metastasizing leiomyoma.

Effect of Rectus Sheath Block on Postoperative Quality of Recovery After Transabdominal Midline Gynecological Surgery: A Randomized Controlled Trial.

Introduction: Rectus sheath block is an emerging technique that provide effective perioperative analgesia and is related to lower perioperative opioid consumption and decrease opioid-related adverse effects. The present research is designed to explore the effect of rectus sheath block on recovery quality in patients following transabdominal midline gynecological surgery. Methods: Ninety female patients following elective transabdominal midline gynecological surgery were enrolled. Patients were randomized to group R (n = 45) which receive preoperative ultrasound-guided RSB with 0.4% ropivacaine or group C which is control group (n = 45). The primary outcome was the quality of recovery on the first postoperative day. The quality of recovery was assessed by the 40-item Quality of Recovery questionnaire (QoR-40). Secondary outcomes included the intraoperative opioid consumption, time to first flatus and time to first discharging from bed, postoperative nausea and vomiting, and patient satisfaction. Results: The patients in two groups had comparable baseline characteristics. Postoperative global QoR-40 scores were significantly better in group R than in group C (165.0[159.5-170.0] vs 155.0[150.0-157.0], respectively; median difference 12[95% confidence interval: 8-15, P<0.001]). Preoperative RSB reduced intraoperative opioid consumption, reduced the time to first flatus, time to first discharging from bed and the post anaesthesia care unit discharge time. Furthermore, group R showed greater patient satisfaction. Conclusion: A single preoperative administration of RSB with ropivacaine improved the quality of recovery in patients following transabdominal midline gynecological surgery.

Although laparoscopic surgery accounts for a higher proportion of gynecological procedures, open gynecological surgery remains irreplaceable for some patients. Recovery from open gynecological surgery is a combination of physical injuries and psychological challenges. Consequently, accelerating functional recovery, alleviating discomfort and improving the quality of recovery in such patients is a clinical issue that we need to focus on. The QoR 40 scale is a patient-reported assessment tool which evaluates the quality of recovery in five dimensions. Ultrasound-guided rectus sheath block is a safe and effective abdominal wall nerve block for anesthesia and analgesia of umbilical and median abdominal longitudinal incisions. This study investigated the impact of rectus sheath block on the quality of postoperative recovery after open gynecological surgery using the QoR40 scale. Participants were randomized to two groups: rectus sheath block treatments and a control group receiving standard care only. Rectus sheath block improves the quality of recovery in patients undergoing open gynecological surgery one day after surgery without adverse effects, which has successfully made rapid rehabilitation from bench to bedside.

Intraoperative Fluorescent Ureter Visualization for Transvaginal High Uterosacral Ligament Suspension for Severe Pelvic Organ Prolapse.

INTRODUCTION AND HYPOTHESIS: We aimed to demonstrate the feasibility of ureteral navigation using intra-ureteric indocyanine green (ICG) and near-infrared fluorescence (NIRF) imaging during transvaginal high uterosacral ligament suspension for prolapse repair to reduce the risk of iatrogenic ureteral injury. METHODS: A cystoscope was inserted into the bladder, the tip of a 6-F open-end ureteral catheter was inserted into the ureteral orifices, and ICG was instilled into the ureters. The ureteral path was then clearly identified using NIRF imaging. Sutures were safely placed in the uterosacral ligaments at the level of the ischial spine, taking advantage of direct ureteral visualization. RESULTS: At the end of the procedure, diagnostic cystoscopy was performed to confirm ureteral patency. No intraoperative or postoperative complications were observed. CONCLUSIONS: Intra-ureteric ICG-NIRF imaging represents a simple, inexpensive, and reproducible trick for intraoperative ureteral detection, and could reassure surgeons during difficult operations, for instance, in the case of severe prolapse and/or when ureteral course abnormalities are expected.

Objective assessment tools in laparoscopic or robotic-assisted gynecological surgery: A systematic review.

INTRODUCTION: There is a growing emphasis on proficiency-based progression within surgical training. To enable this, clearly defined metrics for those newly acquired surgical skills are needed. These can be formulated in objective assessment tools. The aim of the present study was to systematically review the literature reporting on available tools for objective assessment of minimally invasive gynecological surgery (simulated) performance and evaluate their reliability and validity. MATERIAL AND METHODS: A systematic search (1989-2022) was conducted in MEDLINE, Embase, PubMed, Web of Science in accordance with PRISMA. The trial was registered with the Prospective Register of Systematic Reviews (PROSPERO) ID: CRD42022376552. Randomized controlled trials, prospective comparative studies, prospective single-group (with pre- and post-training assessment) or consensus studies that reported on the development, validation or usage of assessment tools of surgical performance in minimally invasive gynecological surgery, were included. Three independent assessors assessed study setting and validity evidence according to a contemporary framework of validity, which was adapted from Messick's validity framework. Methodological quality of included studies was assessed using the modified medical education research study quality instrument (MERSQI) checklist. Heterogeneity in data reporting on types of tools, data collection, study design, definition of expertise (novice vs. experts) and statistical values prevented a meaningful meta-analysis. RESULTS: A total of 19 746 titles and abstracts were screened of which 72 articles met the inclusion criteria. A total of 37 different assessment tools were identified of which 13 represented manual global assessment tools, 13 manual procedure-specific assessment tools and 11 automated performance metrices. Only two tools showed substantive evidence of validity. Reliability and validity per tool were provided. No assessment tools showed direct correlation between tool scores and patient related outcomes. CONCLUSIONS: Existing objective assessment tools lack evidence on predicting patient outcomes and suffer from limitations in transferability outside of the research environment, particularly for automated performance metrics. Future research should prioritize filling these gaps while integrating advanced technologies like kinematic data and AI for robust, objective surgical skill assessment within gynecological advanced surgical training programs.

Risk Factors Asscociated with Hypokalemia during Postanesthesia Recovery and Its Impact on Outcomes in Gynecological Patients: A Propensity Score Matching Study.

OBJECTIVE: This study aimed to explore the risk factors and outcomes of hypokalemia during the recovery period from anesthesia in the gynecological population. METHODS: This retrospective cohort study included 208 patients who underwent gynecological surgery at our institution between January 2021 and March 2022. Data were collected for each patient, including demographics, disease status, surgical data, and clinical information. Preoperative bowel preparation, postoperative gastrointestinal function, and electrolyte levels were compared between the two groups using propensity score matching (PSM). RESULTS: The incidence of hypokalemia (serum potassium level <3.5 mmol/L) during the recovery period from anesthesia was approximately 43.75%. After PSM, oral laxative use (96.4% vs. 82.4%, P=0.005), the number of general enemas (P=0.014), and the rate of ≥2 general enemas (92.9% vs. 77.8%, P=0.004) were identified as risk factors for hypokalemia, which was accompanied by decreased PaCO2 and hypocalcemia. There were no significant differences in postoperative gastrointestinal outcomes, such as the time to first flatus or feces, the I-FEED score (a scoring system was created to evaluate impaired postoperative gastrointestinal function), or postoperative recovery outcomes, between the hypokalemia group and the normal serum potassium group. CONCLUSION: Hypokalemia during postanesthesia recovery period occurred in 43.75% of gynecological patients, which resulted from preoperative mechanical bowel preparation; however, it did not directly affect clinical outcomes, including postoperative gastrointestinal function, postoperative complications, and length of hospital stay.

Role of single port robotic surgery in gynecology.

Robot-assisted Single-Site Laparoscopy (R-LSS) is a rapidly evolving minimally invasive technique. Although it is a very recent technology, the use of R-LSS have been increasingly report in gynecology, for both benign and malignant indications. This review aims to summarize the evolution of this innovative technique and to examine its feasibility and safety for gynecological surgical procedures. We evaluated studies dealing about R-LSS in gynecological surgery. We performed a comprehensive literature research on PubMed and the Cochrane Library in February 2024. Based on the study reviewed, R-LSS seems to be a feasible and effective alternative to other mini-invasive approach in gynecological surgery. R-LSS combine the advantages of robotics surgery with the aesthetic result of a single incision. Compare to Single-Site Laparoscopy, it restore triangulation of the instrument and improve visualization and ergonomic. R-LSS seems to be related to favourable intra-e post-operative outcomes. Although, further studies would be necessary allow us to draw any final conclusion.

A multi-center study to predict the risk of intraoperative hypothermia in gynecological surgery patients using preoperative variables.

OBJECTIVES: Hypothermia is highly common in patients undergoing gynecological surgeries under general anesthesia, so the length of hospitalization and even the risk of mortality are substantially increased. Our aim was to develop a simple and practical model to preoperatively identify gynecological surgery patients at risk of intraoperative hypothermia. METHODS: In this retrospective study, we collected data from 802 patients who underwent gynecological surgery at three medical centers from June 2022 to August 2023. We further allocated the patients to a training group, an internal validation group, or an external validation group. The preliminary predictive factors for intraoperative hypothermia in gynecological patients were determined using the least absolute shrinkage and selection operator (LASSO) method. The final predictive factors were subsequently identified through multivariate logistic regression analysis, and a nomogram for predicting the occurrence of hypothermia was established. RESULTS: A total of 802 patients were included, with 314 patients in the training cohort (mean age 48.5 ± 12.6 years), 130 patients in the internal validation cohort (mean age 49.9 ± 12.5 years), and 358 patients in the external validation cohort (mean age 47.6 ± 14.0 years). LASSO regression and multivariate logistic regression analyses indicated that body mass index, minimally invasive surgery, baseline heart rate, baseline body temperature, history of previous surgery, and aspartate aminotransferase level were associated with intraoperative hypothermia in gynecological surgery patients. This nomogram was constructed based on these six variables, with a C-index of 0.712 for the training cohort. CONCLUSIONS: We established a practical predictive model that can be used to preoperatively predict the occurrence of hypothermia in gynecological surgery patients.

Exploring perioperative risk factors for poor recovery of postoperative gastrointestinal function following gynecological surgery: A retrospective cohort study.

Purpose: To investigate perioperative risk factors that affect the recovery of postoperative gastrointestinal function in patients undergoing gynecological surgery and to establish a preoperative risk prediction scoring system. Methods: In this retrospective cohort study, characteristics and perioperative factors of patients who underwent elective gynecological surgery at Union Hospital from January 2021 to March 2022 were extracted from electronic medical records. Patients were grouped according to the Intake, Feeling nauseated, Emesis, physical Exam, and Duration of symptoms (I-FEED) scoring system to compare collected data. Results: In total, clinical data from 208 gynecological patients were extracted. The incidence of poor postoperative gastrointestinal recovery was 7.21 %. The number of previous abdominal surgeries (0.73 ± 0.06 vs 1.20 ± 0.24, p = 0.044), the incidence of malignant disease (20.2 % vs 53.3 %, p = 0.003), postoperative maximum WBC count (9.15 vs 12.44, p = 0.005) and postoperative minimum potassium (3.97 ± 0.36 vs 3.76 ± 0.37, p = 0.036) were not only associated with poor postoperative gastrointestinal recovery, but also malignant disease (p = 0.000), postoperative maximum WBC count (p = 0.027) and postoperative minimum potassium (p = 0.024) were significantly associated with the severity of postoperative gastrointestinal function. An increased number of previous abdominal surgeries and malignant primary disease could increase the risk of an I-FEED score >2 as independent risk factors. Conclusion: Patients with poor postoperative GI function had poorer postoperative recovery outcomes. A preoperative score prediction system was established, in which patients with ≥2 points had a 19.4 % risk of poor postoperative gastrointestinal recovery. Higher-quality prospective studies should be performed to achieve more precise risk stratification and to construct a more accurate prediction system.

First experience with the Hugo™ robot-assisted surgery system for endometriosis: A descriptive study.

INTRODUCTION: The Medtronic Hugo™ Robot-assisted Surgery (RAS) system was recently approved for clinical use. We explored the safety and feasibility of this system for endometriosis surgery. The primary outcome was safe case completion without major surgical complications (Clavien-Dindo grade ≤2) and no conversion to open surgery or laparoscopy. MATERIAL AND METHODS: Surgeries for endometriosis performed at the Department of Gynecology, Rigshospitalet, on the Medtronic Hugo™ RAS system were included. Two experienced robotic surgeons performed all surgeries with their usual robotic team. The variables included were patient demographics, peri- and postoperative data, complications and 30-day readmission rate. We used the IDEAL framework 1/2a for surgical innovation in this descriptive study. RESULTS: The first 12 patients were included. All cases were completed without intraoperative complications or conversion. Four patients experienced Clavien-Dindo grade 1 postoperative complications. No patients were re-admitted within 30 days. Median docking time (17 minutes), console time (87.5 minutes), blood loss (40 mL) and length of hospital stay (1 day) were acceptable compared with previous literature. CONCLUSIONS: In this pilot study, we found the Medtronic Hugo™ RAS system safe and feasible for robot-assisted surgery for endometriosis. The advent of new robotic systems is welcomed to accelerate the development of technology that will advance surgical care for patients across the globe.

Advantages of laparoscopy in gynecologic surgery in elderly patients.

OBJECTIVE: Geriatric patients requiring gynecological surgery is increasing worldwide. However, older patients are at higher risk of postoperative morbidity and mortality, particularly cardiopulmonary complications. Laparoscopic surgery is widely used as a minimally invasive method for reducing postoperative morbidities. We compared the outcomes of open and laparoscopic gynecologic surgeries in patients older than 55 years. METHODS: We included patients aged >55 years who underwent gynecological surgery at a single tertiary center between 2010 and 2020, excluding vaginal or ovarian cancer surgeries were excluded. Surgical outcomes were compared between the open surgery and laparoscopic groups, with age cutoff was set at 65 years for optimal discriminative power. We performed linear or logistic regression analyses to compare the surgical outcomes according to age and operation type. RESULTS: Among 2,983 patients, 28.6% underwent open surgery and 71.4% underwent laparoscopic surgery. Perioperative outcomes of laparoscopic surgery were better than those of open surgery in all groups. In both the open and laparoscopic surgery groups, the older patients showed worse overall surgical outcomes. However, age-related differences in perioperative outcomes were less severe in the laparoscopic group. In the linear regression analysis, the differences in estimated blood loss, transfusion, and hospital stay between the age groups were smaller in the laparoscopy group. Similar restuls were observed in cancer-only and benign-only cohorts. CONCLUSION: Although the surgical outcomes were worse in the older patients, the difference between age groups was smaller for laparoscopic surgery. Laparoscopic surgery offers more advantages and safety in patients aged >65 years.

PREVALENCE OF AEROBIC VAGINITIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE.

OBJECTIVE: Aim: To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter retrospective cohort study was conducted from January 2020 to December 2022 in fifteen medical clinics from eight regions of Ukraine. Smears were analyzed using Donders' classification method and Dong's modified AV diagnosis for Gram stains. Definitions of HAIs were adapted from the CDC/NHSN. Antibiotic susceptibility testing of bacteria was determined by Kirby-Bauer disc diffusion test according to the protocol of the EUCAST. RESULTS: Results: Prevalence of AV among women's undergoing gynecologic surgery in Ukraine was 68.7%. Of the total AV cases, 70.3% were in non-pregnant and 29,7% in pregnant women. The most common pathogen of AV was Escherichia coli, followed by Enterococcus faecalis, Streptococcus agalactiae, Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Among the S. aureus strains, 11,6% of MRSA (Methicillin resistant S.aureus) were isolated whereas none of the CoNS were cefoxitin resistant. History of vaginal infection, history of post-operative infection and antibiotic use acted as an important risk factor of AV incidence rate. The presence of AV worsened pregnancy outcomes, by increasing the incidence of preterm birth, the premature rupture of membranes, miscarriage, neonatal jaundice, and neonatal infection. CONCLUSION: Conclusions: Aerobic Vaginitis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, adverse pregnancy outcome, and hence frequent medical visits.

The effect of platelet-rich plasma on intra-abdominal adhesions in rabbit uterine horn model.

OBJECTIVE: This study was carried out to investigate the effect of autologous platelet-rich plasma (PRP) on intra-abdominal adhesion at the cesarean section incision line in the uterus. MATERIAL AND METHODS: As experimental animals 16 white New Zealand rabbits, 5-months-old, unmated, were used. Animals were divided into two groups the control group and PRP application group. In each group, a transverse incision was made to the uterus to mimic the cesarean section and sutured. Relaparotomy was performed 21 days after the first operation. RESULTS: When the groups were evaluated in terms of inflammation, there was a significant difference between the two groups. When the groups were evaluated in terms of Mason's Trichrome staining and fibrosis, There was a significant difference between groups. When the groups were evaluated in terms of vascular endothelial growth factor-1, there was also a significant difference between the groups. In an experimental rabbit uterine horn adhesion model, PRP is effective in preventing post-operative adhesion formation. CONCLUSIONS: This result may guide clinical studies using autologous PRP to prevent post-operative adhesion formation after gynecological operations.

OBJETIVO: Este estudio se llevó a cabo para investigar el efecto del plasma rico en plaquetas (PRP) autólogo sobre la adhesión intraabdominal en la línea de incisión de la cesárea en el útero. MATERIAL Y MÉTODOS: Como animales de experimentación se utilizaron 16 conejos blancos de Nueva Zelanda, de 5 meses de edad, sin aparear. Los animales se dividieron en dos grupos como grupo de control y grupo de aplicación de PRP. En cada grupo, se hizo una incisión transversal al útero para imitar la cesárea y se suturó. La relaparotomía se realizó 21 días después de la primera operación. RESULTADOS: Cuando los grupos se evaluaron en términos de inflamación, hubo una diferencia significativa entre los dos grupos. Cuando los grupos se evaluaron en términos de tinción MT y fibrosis, hubo una diferencia significativa entre los grupos. Cuando los grupos se evaluaron en términos de VEGF-1, también hubo una diferencia significativa entre los grupos. En un modelo experimental de adherencia al cuerno uterino de conejo, el PRP es eficaz para prevenir la formación de adherencias posoperatorias. CONCLUSIONES: Este resultado puede guiar los estudios clínicos que utilizan PRP autólogo para prevenir la formación de adherencias postoperatorias después de operaciones ginecológicas.

HEALTHCARE-ASSOCIATED BACTERIAL VAGINOSIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE.

OBJECTIVE: The aim: To determine the prevalence of healthcare-associated bacterial vaginosis after gynecological surgeries and associated adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and methods: Multicenter retrospective cohort study was conducted from January 2019 to December 2021 in eleven medical centers from eight regions of Ukraine. Vaginal cultures were obtained preoperatively from 3,502 women undergoing gynecologic surgery. Diagnosis of Bacterial Vaginosis is based on the Nugent and Amsel criteria. RESULTS: Results: Healthcare-associated bacterial vaginosis (HA BV) was diagnosed in 1,498 of 3,502 women, giving a prevalence rate of 42.8%. HA BV was significantly associated with preterm birth (risk ratio [RR], 2.68; 95% confidence interval [CI], 1.44-4.98), miscarriage (RR, 6.11; 95% CI, 3.22-14.11), low birth weight (RR, 3.20; 95% CI, 1.29-7.94), and premature rupture of membranes (RR, 6.75; 95% CI, 3.11-14.67). CONCLUSION: Conclusions: The HA BV after gynecological surgeries prevalence is high in Ukraine, with a concomitant adverse pregnancy outcome, including preterm birth, low birth weight, premature rupture of membranes, and miscarriage. A significant number of cases of bacterial vaginosis are associated with long-term use of antibiotics to treat post-operative infections.

Feasibility and safety of vNOTES for gynecological procedures in obese patients.

INTRODUCTION: This study aimed to determine the feasibility and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) to treat benign and malign gynecological conditions in obese patients. MATERIAL AND METHODS: We analyzed data from 79 obese patients with a body mass index (BMI) > 30 Kg/m2 operated by vNOTES for gynecological conditions between May 2020 and April 2023. The primary outcome was the feasibility of performing the surgery as initially planned. Data were presented for subgroups of patients with obesity class I (BMI 30.1 - 34.9 Kg/m2), class II (BMI 35.0 - 39.9 Kg/m2), and class III (BMI ≥ 40.0 Kg/m2). RESULTS: Patients presented obesity class I in 39 cases (49.4 %), class II in 27 cases (34.2 %), and class III in 13 cases (16.4 %). Fifty-two patients (65.8 %) underwent vNOTES hysterectomy, 26 patients (32.9 %) underwent procedures limited to the adnexa, and 1 patient (1.3 %) underwent myomectomy. The conversion rate was 0 %, 11.1 %, and 7.7 % in obesity class I, II, and III, respectively. Intraoperative bladder injury was observed in 1 case (1.3 %) and rectal serosal tear in 2 cases (2.5 %). Postoperatively, we observed 3 cases (3.8 %) of wound infection, 2 cases (2.5 %) of cystitis, and 1 case (1.3 %) of deep vein thrombosis. DISCUSSION: This study demonstrated the feasibility and safety of performing gynecological vNOTES procedures in obese patients. However, obesity could be associated with longer and more complex interventions, especially in obesity class II and III patients.

POSTOPERATIVE INFECTIONS AFTER GYNECOLOGICAL SURGERIES IN UKRAINE.

OBJECTIVE: Aim: To determine the current prevalence of surgical site infections (SSIs) after gynecological surgeries and antimicrobial resistance of causing pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective observational cohort study was conducted from January 2020 to December 2022 in nine hospitals from eight regions of Ukraine. Definitions of HAIs were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: A total 12.2% (420/3450) patients who undergoing gynecological surgeries were found to have SSIs. The difference in SSI rates between the three subgroups by route of surgery was not statistically significant, being 12.0% for the abdominal group,11.1% for the vaginal group, and 12.5% for the combined group. The most common causing pathogens of SSIs was Escherichia coli, Pseudomonas aeruginosa, Enterobacter spp., Streptococcus spp., and Klebsiella pneumoniae. Many Gram-negative pathogens isolated from SSI cases were found to be multidrug resistant. CONCLUSION: Conclusions: This study showed that SSIs remains the common complication after gynecological procedures in Ukraine. Best practices should be established and followed to reduce the risk of SSIs associated with gynecologic surgery. Optimizing the antibiotic prophylaxis and empirical antimicrobial therapy may reduce the burden of SSIs in gynecological surgeries, but prevention is the key element.
