A Study of Safety and Effectiveness of Evicel Fibrin Sealant as an Adjunctive Hemostat in Pediatric Surgery.

Data on the use of fibrin sealants to control intraoperative bleeding in children are scarce. Evicel Fibrin Sealant (Ethicon Inc., Raritan, New Jersey, United States) was found safe and effective in clinical trials of adults undergoing various surgery types. We evaluated the safety and efficacy of Evicel versus Surgicel Absorbable Hemostat (Ethicon Inc.) as adjunctive topical hemostats for mild/moderate raw-surface bleeding in pediatric surgery. A phase III randomized clinical trial was designed as required by the European Medicines Agency's Evicel Pediatric Investigation Plan: 40 pediatric subjects undergoing abdominal, retroperitoneal, pelvic, or thoracic surgery were randomized to Evicel or Surgicel, to treat intraoperative mild-to-moderate bleeding. Descriptive analyses included time-to-hemostasis and rates of treatment success (4, 7, 10 minutes), intraoperative treatment failure, rebleeding, and thromboembolic events. Forty of 130 screened subjects aged 0.9 to 17 years were randomized 1:1 to Evicel or Surgicel. Surgeries were predominantly open abdominal procedures. The median bleeding area was 4.0 cm2 for Evicel and 1.0 cm2 for Surgicel. The median time-to-hemostasis was 4.0 minutes for both groups. The 4-, 7-, and 10-minute treatment success rates were 80.0% versus 65.0%, 100.0% versus 80.0%, and 95.0% versus 90.0%, whereas treatment failure rates were 5.0% versus 25.0%, for Evicel and Surgicel, respectively. No deaths or thrombotic events occurred. Re-bleeding occurred in 5.0% of Evicel and 10.0% of Surgicel subjects. In accordance with adult clinical trials, this randomized study supports the safety and efficacy of Evicel for controlling mild-to-moderate surgical bleeding in a broad range of pediatric surgical procedures.

Changes in Stress Urinary Incontinence Symptoms after Pelvic Organ Prolapse Surgery: a Nationwide Cohort Study (FINPOP)

Introduction and hypothesisVarious strategies are employed to manage stress urinary incontinence (SUI) during pelvic organ prolapse (POP) surgery. This study was aimed at facilitating shared decision-making by evaluating SUI symptom changes, staged SUI procedures, and their prognostic factors following POP surgery without concomitant SUI intervention.MethodsWe analyzed 2,677 POP surgeries from a population-based observational cohort, excluding patients with prior SUI surgery. The outcome measures were subjective SUI utilizing the Pelvic Floor Distress Inventory-20 questionnaire and number of subsequent SUI procedures. Multivariable linear models were applied to identify predictors of persistent SUI, procedures for persistent SUI, and de novo SUI. The primary assessment occurred at the 2-year follow-up.ResultsAt baseline, 50% (1,329 out of 2,677) experienced SUI; 35% (354 out of 1,005) resolved, an additional 14% (140 out 1,005) improved, and 5.1% (67 out of 1,308) underwent a procedure for persistent SUI. De novo SUI symptoms developed in 20% (218 out of 1,087), with 3.2% (35 out of 1,087) reporting bothersome symptoms; 0.8% (11 out of 1,347) underwent a procedure for de novo SUI. High baseline symptom severity increased the risk of persistent SUI (adjusted odds ratio [aOR] 2.04, 95% confidence interval [CI] 1.65–2.53), whereas advanced preoperative apical prolapse decreased the risk (aOR 0.89, 95% CI 0.85–0.93). De novo SUI was more common with advancing age (aOR 1.03, 95% CI 1.01–1.05), baseline urgency urinary incontinence (aOR 1.21, 95% CI 1.06–1.38), and after transvaginal mesh surgery (aOR 1.93, 95% CI 1.24–3.00). It was not dependent on the compartment or preoperative degree of prolapse.ConclusionsIn a pragmatic setting, POP surgery results in a low rate of subsequent SUI procedures.

Nomogram for predicting difficult total laparoscopic hysterectomy: a multi-institutional, retrospective model development and validation study.

Total laparoscopic hysterectomy (TLH) is the most commonly performed gynaecological surgery. However, the difficulty of the operation varies depending on the patient and surgeon. Subsequently, patient's outcomes and surgical efficiency are affected. The authors aimed to develop and validate a preoperative nomogram to predict the operative difficulty in patients undergoing TLH. This retrospective study included 663 patients with TLH from Southwest Hospital and 102 patients from 958th Hospital in Chongqing, China. A multivariate logistic regression analysis was used to identify the independent predictors of operative difficulty, and a nomogram was constructed. The performance of the nomogram was validated internally and externally. The uterine weight, history of pelvic surgery, presence of adenomyosis, surgeon's years of practice, and annual hysterectomy volume were identified as significant independent predictors of operative difficulty. The nomogram demonstrated good discrimination in the training dataset [area under the receiver operating characteristic curve (AUC), 0.827 (95% CI, 0.783-0.872], internal validation dataset [AUC, 0.793 (95% CI, 0.714-0.872)], and external validation dataset [AUC, 0.756 [95% CI, 0.658-0.854)]. The calibration curves showed good agreement between the predictions and observations for both internal and external validations. The developed nomogram accurately predicted the operative difficulty of TLH, facilitated preoperative planning and patient counselling, and optimized surgical training. Further prospective multicenter clinical studies are required to optimize and validate this model.

Fluroscopy-assisted transiliac antegrade lag screw placement technique in both columns of acetabulum: A novel procedure

The use of pelvic osseous fixation corridors and lag screw fixation in acetabular and pelvic surgery has gained popularity, especially with the recent development of intraoperative imaging and navigation techniques. However, advanced intraoperative imaging and navigation techniques require technical equipment and are costly. Therefore, traditional fluoroscopic techniques still maintain their importance. In this article, we describe a novel pelvic osseous fixation corridor that traverses both columns of the acetabulum, along with the detailed methodology of its fluoroscopic imaging and the techniques for fluoroscopy-assisted screw placement. The technique of placing screws in this current fixation corridor is only under fluoroscopy assistance, without using any specially produced guide or navigation device. Level of proofIV.

Type of Prior Operation Does Not Predict Surgical Intervention for Small Bowel Obstruction.

Background: Patients with prior abdominal surgeries are at higher risk for intra-abdominal adhesive tissue formation and subsequently higher risk for small bowel obstruction (SBO).Purpose: In this study, we investigated whether surgical intervention for SBO was more likely following specific types of abdominal surgeries.Research Design: With retrospective chart review, we pooled data from 799 patients, ages 18 to 89, admitted with SBO between 2012 and 2019. Patients were evaluated based on whether they underwent surgery or were managed conservatively. They were further compared with regard to past surgical history by way of type of abdominal surgery (or surgeries) undergone prior to admission.Results: Of the 799 patients admitted for SBO, 206 underwent surgical intervention while 593 were managed nonoperatively. There was no significant difference in number of prior surgeries (2.07±1.56 vs 2.36±2.11,P = .07) or in number of comorbidities (2.39±1.97 vs 2.65±1.93,P= .09) for surgical vs non-surgical intervention. Additionally, of the operations evaluated, no specific type of abdominal surgery predicted need for surgical intervention in the setting of SBO. However, for both surgical and non-surgical intervention following SBO, pelvic surgery was the most common type of prior abdominal surgery (45% vs 43%). There are significantly more female pelvic surgeries in both the operative (91.4% vs 8.6%,P< .0001) and nonoperative groups (89.9% vs 10.2%,P< .0001).Conclusion: Ultimately, no specific type of prior operation predicted the need for surgical intervention in the setting of SBO.

The Future of Basic Science: Development of the Next Generation of Mechanistic Researchers in Female Pelvic Medicine.

The International Urogynecological Association (IUGA) brought together senior and junior members actively engaged in scholarly and educational activities for a consensus conference centered on developing a strategy for sustainable training of the next generation of mechanistic researchers in female pelvic medicine. Four a priori identified major foci were explored in a half-day virtual consensus conference. Participants included representatives from various countries and disciplines with diverse backgrounds-clinicians, physician-scientists, and basic scientists in the fields of urogynecology, biomechanical engineering, and molecular biology.Following a keynote address, each focus area was first tackled by a dedicated breakout group, led by the Chair(s) of the most relevant IUGA committees. The break-out sessions were followed by an iterative discussion among all attendees to identify mitigating strategies to address the shortage of mechanistic researchers in the field of female pelvic medicine. The major focus areas included: research priorities for IUGA basic science scholar program; viable strategies for sustainable basic science mentorship; core competencies in basic science training; and the challenges of conducting complex mechanistic experiments in low-resource countries. Key gaps in knowledge and core competencies that should be incorporated into fellowship/graduate training were identified, and existing training modalities were discussed. Recommendations were made for pragmatic approaches to increasing the exposure of trainees to learning tools to enable sustainable training of the next generation of basic science researchers in female pelvic medicine worldwide. The attendees presented multiple perspectives to gain consensus regarding critical areas of need for training future generations of mechanistic researchers. Recommendations for a sustainable Basic Science Scholar Program were developed using IUGA as a platform. The overarching goal of such a program is to ensure a successful bench-to-bedside-and-back circuit in Urogynecology and Pelvic Reconstructive Surgery, ultimately improving lives of millions of women worldwide through scientifically rational effective preventative and therapeutic interventions.

Complications of obliterative versus reconstructive vaginal surgery for pelvic organ prolapse in octogenarians: A retrospective cohort study.

Women of advanced age may choose between restorative or obliterative surgery for surgical management of pelvic organ prolapse. Obliterative surgery is traditionally reserved for a subset of older women with more severe medical comorbidities, since obliterative approaches are generally considered to be less morbid and older individuals have higher rates of perioperative complications than younger cohorts. This study compared perioperative complications amongst octogenarians undergoing obliterative versus reconstructive approaches. This data will help to inform perioperative counselling as previous studies have not been powered to evaluate complications in this population. The National Surgical Quality Improvement Program database was used to identify patients that had Pelvic organ prolapse surgery between 2012 and 2021, aged 80 years or older. Single-compartment procedures, vaginal mesh procedures, and oncologic surgery were excluded. The primary outcome was any complication within the first 30 days excluding urinary tract infection (UTI). UTI, readmission, and severe complications were secondary outcomes. Of the 4149 patients identified, 2514 (60.6%) underwent reconstructive surgery and 1635 (39.4%) underwent obliterative surgery. Patients undergoing reconstructive surgery were more likely to have an American Society of Anesthesiologists (ASA) class of 1 or 2 (46.1% vs. 31.3%, p = 0.002) and were less likely to be on antihypertensive medication (72.0% vs. 75.8%, p = 0.006). Further, there was an increased length of stay (1.47 ± 1.84 vs. 1.03 ± 1.31 days, p < 0.001) in hospital for reconstructive surgery which was more often performed as an inpatient (45.7% vs. 37.9%, p < 0.001). There was no difference in the primary outcome: any complication excluding UTIs. However, UTI was more common in the reconstructive group (aOR 0.48; 95% confidence interval 0.34-0.0). The rate of serious complications (Clavien-Dindo Class IV) was low overall and not different between reconstructive and obliterative approaches (1.3% vs. 1.0%, respectively). Both vaginal reconstructive and obliterative approaches have low complication rates in octogenarians, with only UTIrate being different between cohorts. When choosing surgical approach, we suggest a case-based, patient center discussion on the anatomic outcomes, durability and patient satisfaction.

The effect of advanced age on peri- and post-operative complications following pelvic floor repair surgeries.

To assess whether advanced age is a risk factor for complications following pelvic organ prolapse (POP) repair surgeries using the Clavien-Dindo classification system. In this retrospective cohort study, 260 women who had undergone POP repair surgery at the Soroka University Medical Center (SUMC) between the years 2014-2019 were included. A univariate analysis was conducted to compare the demographical, clinical, obstetrical and operative characteristics of patients by age group (younger or older than 70years). We performed a similar analysis to assess for the possible association between several variables and post-operative complications. Variables that were found to be associated with post-operative complications (P < 0.2) were included in a multivariate analysis along with advanced age. During the 12months follow-up period, more than half of the women had experienced at least one post-operative complication. Minor complications (grades 1-2 according to the Clavian-Dindo classification system) were the most common. One woman had died during the follow-up period, and none had experienced organ failure (grade 4). Hysterectomy, as part of POP surgery, was found to be significantly associated with post-operative complications. Additionally, grandmultiparity (> 5 births) showed a tendency towards an increased risk for post-operative complications, however this reached only borderline significance. We found no association between advanced age and post-operative complications. POP repair surgeries are safe for women of all ages. Major complications (grades 3-5) are rare in all age groups. Although advanced age was associated with a higher prevalence of comorbidity and a higher grade of prolapse, no significant difference in the post-operative complications was found between age groups. Concomitant hysterectomy at the time of POP repair surgery is a risk factor for post-operative complications.

A dual-camera hyperspectral laparoscopic imaging system.

Minimally invasive surgery (MIS) has expanded broadly in the field of abdominal and pelvic surgery. However, there are still prevalent issues surrounding intracorporeal surgery, such as iatrogenic injury, anastomotic leakage, or the presence of positive tumor margins after resection. Current approaches to address these issues and advance laparoscopic imaging techniques often involve fluorescence imaging agents, such as indocyanine green (ICG), to improve visualization, but these have drawbacks. Hyperspectral imaging (HSI) is an emerging optical imaging modality that takes advantage of spectral characteristics of different tissues. Various applications include tissue classification and digital pathology. In this study, we developed a dual-camera system for high-speed hyperspectral imaging. This includes the development of a custom application interface and corresponding hardware setup. Characterization of the system was performed, including spectral accuracy and spatial resolution, showing little sacrifice in speed for the approximate doubling of the covered spectral range, with our system acquiring 29 spectral images from 460-850 nm. Reference color tiles with various reflectance profiles were imaged and a RMSE of 3.56 ± 1.36% was achieved. Sub-millimeter resolution was shown at 7 cm working distance for both hyperspectral cameras. Finally, we image ex vivo tissues, including porcine stomach, liver, intestine, and kidney with our system and use a high-resolution, radiometrically calibrated spectrometer for comparison and evaluation of spectral fidelity. The dual-camera hyperspectral laparoscopic imaging system can have immediate applications in various surgeries.

Limb Salvage and Pelvic Reconstruction With Endoprosthesis After Pelvic Tumor Resection: A Narrative Review.

Periacetabular defects following tumor resection present formidable challenges in reconstruction and continue to pose clinical difficulties. Historically, treatment approaches leaned towards hindquarter amputation; however, due to associated morbidities and functional limitations, limb-sparing procedures gained prominence in the 1980s. Nevertheless, the intricacies of pelvic anatomy and the imperative of achieving wide surgical margins while preserving essential structures make pelvic tumor resection and subsequent reconstruction inherently complex. Various reconstruction modalities have been explored, including non-vascularized fibular grafts and prosthetic implants. Among these options, the LUMiC® endoprosthesis stands out as a promising solution for pelvic reconstruction post-tumor resection. Characterized by a modular design featuring a hydroxyapatite-coated stem and acetabular cup, this device has shown favorable implant survival rates in studies, despite encountering complications primarily associated with soft tissue failure, dislocation, and infection. Notably, the incidence of complications varies across studies. The Henderson classification system delineates these complications, encompassing soft tissue issues, aseptic loosening, periprosthetic fractures, infections, and tumor recurrence. Despite the encouraging functional outcomes associated with the LUMiC® endoprosthesis, it is not immune to limitations. Concerns persist regarding complications such as dislocation and infection, underscoring the imperative for further research to evaluate the long-term durability and reliability of this reconstructive approach. Moreover, advancements in surgical techniques, perioperative management, and the advent of navigation-assisted procedures hold promise for enhancing outcomes and mitigating complication rates in pelvic reconstruction surgeries.

The Association of Acetabulum Fracture and Mechanism of Injury with BMI, Days Spent in Hospital, Blood Loss, and Surgery Time: A Retrospective Analysis of 67 Patients.

Background and Objectives: The objective of this retrospective study was to investigate the association between acetabulum fractures; the mechanism of injury; and variables such as BMI, duration of hospital stay, blood loss, and surgery time. By exploring these factors, we aim to enhance our understanding of them and their impact on the healing process and the subsequent management of pelvic fractures. Materials and Methods: This study included 67 of 136 consecutive patients who were admitted for pelvic ring fracture surgery between 2017 and 2022. The data were collected prospectively at a single trauma center. The inclusion criteria were acetabulum fractures and indications for operative treatment. The exclusion criteria were non-operative treatment for acetabular and pelvic ring fractures, fractures requiring primary total hip arthroplasty (THA), and periprosthetic acetabular fractures. Upon admission, all patients underwent evaluation using X-ray and computed tomography (CT) scans of the pelvis. Results: The present study found no statistically significant differences between the examined groups of patients with pelvic fractures in terms of BMI, surgery duration, length of hospital stay, and blood transfusion. However, two notable findings approached statistical significance. Firstly, patients who experienced a fall from height while sustaining a pelvic fracture required a higher number of blood transfusions (2.3 units) than those with other mechanisms of injury which was close to achieving statistical significance (p = 0.07). Secondly, patients undergoing posterior wall stabilization required a significantly lower number of blood transfusions than those with other specific pelvic injuries (0.33 units per patient), approaching statistical significance (p = 0.056). Conclusions: The findings indicated that factors such as BMI, time of surgery, blood loss, and the duration of hospital stay were not directly correlated with the morphology of acetabular fractures, the presence of additional trauma, or the mechanism of injury. However, in the studied group, the patients whose mechanism of trauma involved falling from height had an increased number of blood transfusions compared to other groups. Moreover, the patients who had surgery due to posterior wall acetabulum fracture had decreased blood transfusions compared to those with other Judet and Letournel types of fractures. Additionally, they had the shortest duration of surgery.

Impact of low-intensity extracorporeal shockwave therapy on vascular parameters and sexual function in patients with arteriogenic erectile dysfunction.

Previous published studies have shown an improvement of penile hemodynamic parameters after low-intensity extracorporeal shockwave therapy (Li-ESWT). However, the clinical significance of these findings remains unclear, and definitive selection criteria for Li-ESWT based on preexisting comorbidities have yet to be established. This was an observational study of 113 patients with ED, evaluated between January 2019 and December 2021 in Andrology Unit at the Department of Urology and Renal Transplantation, University of Foggia (Foggia, Italy). Penile dynamic Doppler was performed to evaluate vascular parameters and 5-item version of the International Index of Erectile Dysfunction (IIEF-5) questionnaire was administered to assess the severity of ED. This was repeated 1 month after treatment. Patients with a peak systolic velocity (PSV) <30 cm s -1 were considered eligible for Li-ESWT. Our protocol consisted of 8 weekly sessions with 1500 strokes distributed in 5 different locations along the penis. After treatment, a significant mean (±standard deviation [s.d.]) PSV increase of 5.0 (±3.4) cm s -1 was recorded and 52/113 (46.0%) patients reached a PSV >30 cm s -1 at posttherapeutic penile dynamic Doppler. A clinically significant IIEF-5 score improvement was observed in 7 patients, 21 patients, and 2 patients with mild-to-moderate, moderate, and severe pretreatment ED, respectively. No different outcomes were assessed based on smoking habits, previous pelvic surgery, or use of oral phosphodiesterase-5 inhibitor (PDE5i). On the other side, only 1 (6.7%) in 15 patients with diabetes mellitus showed an IIEF-5 score improvement after Li-ESWT. Shockwave treatment determined a significant increase in PSV and correlated IIEF-5 improvement in ED patients. This advantage seemed particularly evident for moderate ED and was not affected by smoking habits, previous pelvic surgery, and use of PDE5i. Conversely, diabetic patients did not benefit from the treatment.

(178) Climacturia: Emerging Type of Urinary Incontinence, Its Prevalence, Risk Factors, and Management: A Systematic Review and Prevalence Meta-analysis

Abstract Introduction Climacturia is an emerging type of urinary incontinence which occurs immediately following orgasm. Both men and women may suffer from climacturia in equivocal rates. This phenomenon is becoming more problematic as it impacts physiological and psychosexual aspect of well-being and quality of life. While awareness of climacturia becomes evident, studies are inadequate to support evidenced-based management in primary and urologic care settings. Objective This study aimed to conduct a systematic review and prevalence meta-analysis of climacturia and investigate its risk factors and evidenced-based management. Methods A systematic review of 24 articles were conducted following PRISMA 2020 guidelines. The PubMed, CINAHL, and Cochrane Library database were searched using the word “climacturia” and phrase “orgasm associated urinary incontinence” respectively. Search limiters applied included literature written in English from year of inception to 2022. Title and abstract reviews were conducted on 78 articles. Articles which did not discuss climacturia, duplicates, and previous systematic reviews were excluded after full article review. Results The review accounts a total of N = 7798 subjects which are composed of N = 7629 (97.83%) males and N = 169 (2.17%) females with age range of 18 to 80 years old. A total of N = 2, 039 (26%) participants are with climacturia, N = 87 or 4.26% are females and N = 1, 931 or 95.74% are males. The risk factors associated with climacturia include sexually active male, history of prostate cancer after prostatectomy within 12 months of surgery or radiation therapy, increased Body Mass Index (BMI), erectile dysfunction (ED), increased urethral width, presence of urinary incontinence, pain-associated orgasm and loss of penile length after pelvic surgery, use of aides to obtain an erection, and increased incontinence scores for men. For women, the risk factors are high scores of female sexual function index (FSFI) and detrusor overactivity. The management for females is limited to pharmacologic therapy with use of antimuscarinic agents. While, behavioral therapy, pharmacologic regimen, pelvic floor muscle training (PFMT), surgery (sling procedure) are the management options for affected men. Conclusions Climacturia affects males more than females, however, the evidence to support the efficacy of treatment options for both sexes are equally inadequate. Primary care and Advanced Practice Providers in primary and urologic care settings are at best position to query patients for the presence of and manage climacturia in timely manner. Further research is needed to increase evidence supporting effective management of climacturia for both men and women. Disclosure No.

(285) Heme-Binding Protein 1 Delivered via Pericyte-Derived Extracellular Vesicles Improves Neurovascular Regeneration in a Mouse Model of Cavernous Nerve Injury

Abstract Introduction As a peripheral nerve injury disease, cavernous nerve injury (CNI) caused by prostate cancer surgery and other pelvic surgery causes organic damage to cavernous blood vessels and nerves, thereby significantly attenuating the response to phosphodiesterase-5 inhibitors. Objective Here, we investigated the role of heme-binding protein 1 (Hebp1) in erectile function using a mouse model of bilateral CNI, which is known to promote angiogenesis and improve erection in diabetic mice. Methods To investigate the efficacy and mechanism of Hebp1 in restoring erectile function in CNI-induced ED mice, we injected recombinant mouse Hebp1 protein into the penis of CNI-induced ED mice. Detailed mechanisms were assessed using Signaling Explorer Antibody Arrays on penile tissue from CNI-induced ED mice; MPG tissue and Schwann cells were cultured in the presence of 2.5 μg/ml LPS. Results We found a potent neurovascular regenerative effect of Hebp1 in CNI mice, demonstrating that exogenously delivered Hebp1 improved erectile function by promoting the survival of cavernous endothelial-mural cells and neurons. We further found that endogenous Hebp1 delivered by mouse cavernous pericyte (MCP)-derived extracellular vesicles promoted neurovascular regeneration in CNI mice. Moreover, Hebp1 achieved these effects by reducing vascular permeability through regulation of claudin family proteins. Conclusions Our findings provide new insights into Hebp1 as a neurovascular regeneration factor and demonstrate its potential therapeutic application to various peripheral nerve injuries.

(199) The Impact of Body Weight on Sexual Function on Woman

Abstract Introduction Female sexual dysfunction (FSD) is a complex disorder which has an impact on women regardless of their age and race, and related to a variety of biological, psychological, and social determinants. Sexuality impact quality of life through effects on the emotional and psychological health of a woman. Objective The purpose of this study is to investigate the impact of body weight on sexual function in women. The associations of sexual function with demographic and clinical variables were evaluated. Methods We performed a cross-sectional study of comparing female sexual function index in normal weight and obese women. Patients with a diagnosis of benign gynecologic disease who admitted for gynecological surgery at our institution from January 2012 to December 2015 were evaluated. Total 349 women were enrolled in this study and complete the Female Sexual Function Index (FSFI) questionnaires. 264 women in normal weight group (body mass index, BMI &amp;lt;25 kg/m2) and 85 women in obese group (BMI ≥ 25 kg/m2) participated. Risk factors for female sexual function were examined using logistic regression models. We used a two-sample t-test and chi-square test for the categorical variables. Mann-Whitney U test for continuous variables and Fisher’s exact test for categorical variables Results The mean BMIs were 21.6±1.95 (mean±SD, kg/m2) in normal weight group and 27.6±2.56 in obese group (p &amp;lt; 0.001). There were also significant differences in age (mean±SD, 43.3±10.17 vs. 46.9±8.70 years, p = 0.002), parity (mean±SD, 1.5±0.99 vs. 1.9±1.19, p = 0.001), vaginal parity (mean±SD, 1.1±1.06 vs. 1.5±1.38, p = 0.043), marriage status (80.7% vs. 89.4%, p = 0.046) and hypertension (6.1% vs. 15.3%, p = 0.012). There were no differences in postmenopausal status, prior history of pelvic reconstructive surgery and urinary symptoms. In comparison of FSFI scores, there were significant differences in total score and all 6 domain scores (Desire, Arousal, Lubrication, Orgasm, Satisfaction and pain) between normal weight and obese group (p &amp;lt; 0.001). In the multiple logistic regression model for female sexual dysfunction, BMI, menopause and marriage were significantly different. Conclusions This study suggests that obesity has some impact on female sexual function. And menopause and marriage status are also associated with female sexual dysfunction. As obese woman population is increasing, the further study will be needed in a larger subgroup of women with long-term follow up period Disclosure No.

Perineal hernia repair following tailgut cyst excision: A case report and literature review of optimal management strategies

Perineal hernias, categorised as primary or secondary, pose a clinical challenge necessitating surgical intervention. Herein we present the surgical management of a postoperative perineal hernia of the retrorectal space. A 42-year-old female patient presented to the clinic with symptoms such as perineal discomfort, bulging, and constipation after previous surgical tailgut cyst excision. Diagnosis involved MRI, confirming rectal herniation into the retrorectal space. The surgical approach featured a perineal intervention using a unilateral inferior gluteal flap to reinforce the posterior rectal space, avoiding mesh complications. The patient experienced a successful recovery, highlighting the importance of tailored interventions based on symptoms and complications. Secondary perineal hernias, often postoperative, present diverse challenges influenced by multiple factors such as pelvic surgeries. Surgical repair options include perineal and abdominal approaches, mesh usage, and flap methods, each with variable outcomes. This case study contributes to the evolving understanding of perineal hernias, emphasising the need for multidisciplinary approaches and ongoing research to enhance management strategies in this complex clinical scenario.
