Accidental laceration of the vaginal wall by an intravaginal thermometer as a calving detection device in a Japanese black cow.

An intravaginal thermometer was inserted into a 59-month-old Japanese black cow to predict calving. After calving, the thermometer penetrated the vaginal wall and could not be removed by farm staff. Surgery to remove the thermometer was successful. The cow left the animal hospital without hospitalization. In the follow-up, the cow remained healthy on the farm for more than one year and is now pregnant. No symptoms related to damage to the vagina or infection developed. This is the first case report of a vaginal laceration caused by an intravaginal thermometer in a Japanese black cow. Insertional vaginal devices may cause vaginal lacerations in cattle.

Vaginal distention rodent model for fecal incontinence: a pilot study on the effect on defecation behavior

Objectives: Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence, the present paper aimed to investigate the effect of VD on defecation behavior in adult rats. Methods: Vaginal distention was performed in 8 rats for 2 hours, and in 3 rats for 4 hours, and sham inflation was performed in 4 rats. With the use of a latrine box in the rat home-cage and 24/7 video tracking, the defecation behavior was examined. The time spent in and outside the latrine was monitored for two weeks preoperatively and three weeks postoperatively, and a defecation behavior index (DBI; range: 0 [continent] to 1 [incontinent]) was defined. Pelvic floor tissue was collected postmortem and stained with hematoxylin and eosin. Results: Vaginal balloon inflation for 2 hours resulted in fecal incontinence in 29% of the animals (responders) whereas the DBI scores of non-responders (71%) and control animals did not change in the postoperative phase compared with the baseline score. A 4-hour balloon inflation resulted in fecal incontinence in 1 animal and caused a humane endpoint in 2 animals with markedly more tissue damage in the 4-hour responder compared with the 2-hour responders. Conclusions: Vaginal balloon inflation, with an optimum duration between 2 and 4 hours, can be used as a model to study changes in defecation behavior in rats induced by pelvic floor damage. (AU)

Sangrado genital por cuerpo extraño en niñas prepuberales: a propósito de un caso / Genital bleeding caused by foreign body in prepubertal girls: a case report

El sangrado genital en niñas prepúberes es un signo poco frecuente y siempre requiere determinar su causa.

A detailed history and physical examination are needed, with adequate knowledge of urogynecological anatomy, and in many cases, imaging studies and complementary tests, to arrive at the diagnosis. We present the case of a 7-year-old girl with genital bleeding, whose physical examination and complementary studies were inconclusive, requiring an invasive procedure for its resolution. (AU)

Vaginal Complications after Cystectomy: Results from a Medicare Sample.

PURPOSE: Cystectomy with a vaginal-sparing approach may be associated with unique complications specific to the female population. The objective of this study was to estimate the incidence of vaginal complications (defined to include vaginal prolapse, vaginal fistula, dyspareunia and vaginal cuff dehiscence/evisceration) after cystectomy and to determine risk factors for these complications. MATERIALS AND METHODS: Women 65 years or older undergoing cystectomy for any indication were identified by procedural codes in the Medicare Limited Data Set 5% sample from January 1, 2011 to December 31, 2017. Patients experiencing a vaginal complication after cystectomy were compared to those who did not. Demographic and biological factors that could increase likelihood of complications were identified and time to development of complications determined. Cumulative incidence was calculated using cumulative incidence function. Multivariable cause-specific Cox proportional hazards model assessed risk factors for vaginal complications. RESULTS: In all, 481 women undergoing cystectomy were identified during the study period, and 37.2% were younger than 70 years old. The majority (378, 79%) had bladder cancer, and 401 (83.4%) underwent an incontinent conduit or catheterizable channel diversion. Within 2 years of cystectomy, 93 patients (19.5%) had 1 or more complications on record. Vaginal cuff dehiscence had the highest cumulative incidence, occurring in 49 patients (10.2%). Over the entire study period (2011-2017), 102 women (21.2%) were diagnosed with a vaginal complication, and 27 (5.6%) received an intervention. CONCLUSIONS: Among women who undergo cystectomy, vaginal complications occur at rates higher than expected with over 20% of women experiencing a complication and over a quarter of those diagnosed undergoing intervention.

Design and Validation of an Automated Dilator Prototype for the Treatment of Radiation Induced Vaginal Injury.

Vaginal stenosis (VS) is a common late complication of radiation injury caused by cervical cancer radiotherapy. It is characterized by the narrowing or shortening of the vaginal canal, which is often detrimental to patient quality of life. To address this public health problem, an expandable vaginal dilator was designed for the prevention of VS in cervical cancer survivors. Modeling and benchtop experimentation were used to iteratively characterize the relationship among dilator pressure, expansion, and the load applied to the simulated vaginal wall. Both experimental and simulation results exhibited shared trends relating pressure, dilator expansion, applied load, and resultant displacement of the modeled vaginal walls. Future work will incorporate enhanced Mooney-Rivlin material assumptions and validation of the model with in vivo tests.Clinical Relevance- These results present a design opportunity and treatment paradigm shift to increase patient adherence to VS treatment after cervical cancer radiotherapy. Specifically, gradual expansion of the vaginal dilator increases comfort during the expansion of the vagina, while monitoring the dilator pressure enables the tracking of VS improvement and normalization of vaginal wall compliance.

Focusing on long-term complications of mid-urethral slings among women with stress urinary incontinence as a patient safety improvement measure: A protocol for systematic review and meta-analysis.

BACKGROUND: There are 3 different types of mid-urethral sling, retropubic, transobturator and single incision performed for women with stress urinary incontinence. Prior studies comparing these three surgeries merely focused on the successful rate or efficacy. But nevertheless, what is more clinically important dwells upon investigating postoperative complications as a safety improvement measure. METHODS: A systematic review via PubMed, Ovid, and the Cochrane Database of Systematic Review and studies were applied based on the contents with clearly identified complications. Selected articles were reviewed in scrutiny by 2 individuals to ascertain whether they fulfilled the inclusion criteria: complications measures were clearly defined; data were extracted on study design, perioperative complications, postoperative lower urinary tract symptoms, postoperative pain, dyspareunia, and other specified late complications. RESULTS: A total of 55 studies were included in the systemic review. Perioperative complications encompassed bladder perforation, vaginal injury, hemorrhage, hematoma, urinary tract infection. There were postoperative lower urinary tract symptoms including urine retention and de novo urgency. Furthermore, postoperative pain, tape erosion/ extrusion, further stress urinary incontinence surgery, and rarely, deep vein thrombosis and injury of inferior epigastric vessels were also reported. CONCLUSIONS: Complications of mid-urethral sling are higher than previously thought and it is important to follow up on their long-term outcomes; future research should not neglect to address this issue as a means to improve patient safety.

Beef Tongue Surgical Simulation Model for Posterior Vaginal Repair.

BACKGROUND: This surgical simulation model for vaginal posterior repair is designed to enhance vaginal surgical training. METHODS: A beef tongue simulation model was previously described and validated to practice the repair of obstetric laceration. The model was modified for surgical simulation of vaginal posterior repair. Chicken skin was used to simulate the anal canal. The model was secured in a PVC (polyvinyl chloride) pipe attached to a wooden base to simulate operating within the vaginal canal. EXPERIENCE: Materials can be obtained from the local supermarket and hardware store. The total cost of the model is $35.47 for initial setup and $7.11 per use. Residents performing on the model felt it was realistic and useful for practicing the steps and skills for this procedure. CONCLUSION: The beef tongue simulation model of vaginal posterior repair is realistic, easy to construct, and affordable. It can be incorporated into a vaginal surgery curriculum to augment resident surgical education.

Clinical Presentation, Treatment, and Challenges in the Management of Child Sexual Assault at a Tertiary Care Referral Center in India.

BACKGROUND: Child Sexual Assault (CSA) is not an uncommon but an under-reported crime. Along with social and psychological critical issues, there are multiple challenges faced by the surgical team for the treatment of complex perineal injuries associated with CSA. This study was conducted to find clinical presentation and management of CSA along with its problems and challenges encountered by the pediatric surgical team. MATERIALS AND METHODS: This was a retrospective study from 2010 to 2019, conducted in the department of pediatric surgery at a tertiary referral center. All-female patients with a definitive history of sexual assault were included in the study. RESULTS: Seven patients fulfilled the inclusion criteria and the mean age was 5.3 years. After a primary survey, all patients were taken up for examination under anesthesia (EUA). Three patients were managed by the primary repair of the wound and did well during follow-up. Four patients had grade 4 perineal injury and required stage reconstruction. As a first stage, repair of rectal tear, vaginal tear, and the perineal body reconstruction was done along with diversion colostomy. One patient required redo repair of the perineal body and one had developed a rectovaginal fistula. Three patients completed all stages and they are fully continent. CONCLUSION: The spectrum of injuries varies widely in CSA and more chances of high-grade perineal injuries in children due to distinctive local anatomy. EUA is crucial to assess the extent of the injury and to decide the course of management. Meticulous anatomical repair and diversion stoma is the key for successful complex repair and excellent long-term outcomes in terms of continence for the severe grade of perineal injuries.

Surgical repair of an obstetric cloaca with review of the literature.

A complete perineal wound breakdown of a fourth degree laceration leading to a cloaca is a rare but devastating complication of vaginal childbirth. A 32-year-old primiparous woman presented with an obstetric cloaca 4 months following delivery. She underwent preoperative evaluation and, following extensive counselling, elected to proceed with operative repair. The procedure is presented in 15 well-defined steps with photos. The repair was performed in standard fashion with three supplementary steps. These included: (1) division of the rectovaginal tissue into three distinct layers; (2) attachment of these layers individually to the reconstructed perineal body and sphincter and (3) incorporation of the levator muscles into the repair. The wound healed well within 6 weeks of repair. Now 3½ years postoperatively, the patient has no faecal incontinence or sexual dysfunction and only minimal defecatory dysfunction. The discussion describes our surgical approach in the context of a review of the literature.

An Avant-Garde Model of Injury-Induced Regenerative Vaginal Wound Healing.

Objective: To design and validate a novel murine model of full-thickness (FT) vaginal wound healing that mirrors postinjury tissue repair and underscores the impact of estrogen signaling-driven healing kinetics, inflammation, and neovascularization. Approach: Five-week-old female CD1 mice were subjected to two 1-mm FT wounds. To assess wound healing kinetics, vaginas were harvested at 6, 12, 18, 24, 48, and 72 h and 7 days postinjury. Wounds from all time points were analyzed by hematoxylin and eosin and trichrome to, respectively, assess the rate of wound closure and tissue deposition. Inflammatory leukocyte (CD45), neutrophil (Ly6G), and macrophage (F480 and CD206) infiltration was examined by immunohistochemistry (IHC) and the resulting anti-inflammatory M2 (CD206)/total (F480) macrophage ratio quantified. Neovascularization (CD31) and estrogen receptor-α (ERα) expression levels were similarly determined by IHC. Results: We observed rapid healing with resolution of mucosal integrity by 48 h (p < 0.05), and overall neutrophils and polarized type 2 macrophages (M2) apexed at 12 h and reduced to near control levels by day 7 postinjury. Tissue repair was virtually indistinguishable from the surrounding vagina. CD31+ vessels increased between 12 h and day 7 and ERα trended to decrease at 12 h postinjury and rebound at day 7 to uninjured levels. Innovation: A proof-of-concept murine model to study vaginal wound healing kinetics and postinjury regenerative repair in the vagina was developed and verified. Conclusion: We surmise that murine vaginal mucosal repair is accelerated and potentially regulated by estrogen signaling through the ERα, thus providing a cellular and molecular foundation to understand vaginal healing responses to injury.

Desgarro perineal con mucosa vaginal íntegra tras primera relación sexual / Perineal tear with intact vaginal mucosa after first sexual intercourse

RESUMEN Las lesiones del tracto genital femenino tras relaciones sexuales son un problema frecuente en las urgencias de ginecología, pero poco estudiado salvo su aspecto médico-legal. Su incidencia es desconocida ya que muchas mujeres no llegan a consultar por miedo o pudor. El reconocimiento precoz de estas lesiones y su correcto tratamiento puede evitar la parición de secuelas que acompañarán a nuestra paciente durante el resto de su vida. Presentamos el caso de una paciente de 18 años con un desgarro perineal con mucosa vaginal íntegra tras su primera relación sexual.

ABSTRACT Injuries to the female genital tract after sexual intercourse are a frequent problem in gynecological emergencies, but little studied except for their medico-legal aspect. Its incidence is unknown since many women do not go to their specialist out of fear or embarrassment. Early recognition of these injuries and their correct treatment may prevent the appearance of sequelae that will accompany our patient for the rest of her life. We present the case of an 18-year-old patient with a perineal tear with intact vaginal mucosa after her first sexual intercourse.

A Laparoscopic Approach to Postcoital Vaginal Perforation in an Adolescent with Peritonitis and Hypovolemic Shock.

BACKGROUND: Vaginal laceration during coitus is not a rare occurrence; however, vaginal perforation from coitus is uncommon and occurs in less than 1% of nonobstetric genital tract injuries. Limited case reports exist discussing the recognition and management of vaginal perforation. Previously described management is commonly performed with laparotomy. CASE: We report a case of postcoital vaginal laceration and posterior fornix perforation in an adolescent with hemoperitoneum, pneumoperitoneum, and subsequent hypovolemic shock, and describe a laparoscopic approach for repair. SUMMARY AND CONCLUSION: Vaginal perforation with subsequent peritonitis and hemodynamic instability is a rare outcome in an adolescent who presents to the emergency department with pain or bleeding in the setting of recent penile intercourse. Delays in recognition can lead to further patient compromise, with potential morbidity or mortality. In this patient cohort, we suggest maintaining a high clinical suspicion for this sequela, and a low threshold for surgery with perforations greater than 1 cm. In the event that surgical management is warranted, we recommend a laparoscopic approach to increase visibility and to improve postoperative outcomes.

Emergency laparoscopic repair of coitus-induced vaginal cuff dehiscence: a case report.

BACKGROUND: Vaginal cuff dehiscence is a rare but potentially grave complication after total hysterectomy. Abdominal or pelvic contents are at risk of evisceration through the vaginal opening. It is associated with significant risk for patient morbidity, such as peritonitis, bowel injury, and sepsis. CASE PRESENTATION: We report a case of vaginal cuff dehiscence in a 45-year-old multiparous Taiwanese woman who had undergone abdominal total hysterectomy and presented with vaginal cuff dehiscence precipitated by sexual intercourse. Immediate laparoscopic repair was done. Few authors have reported the utilization of the laparoscopic approach. It allows thorough inspection, visualization, and irrigation of the abdominal cavity. It is also associated with fewer intraoperative and postoperative complications. CONCLUSION: Laparoscopic repair is a safe treatment option to manage vaginal cuff dehiscence after total hysterectomy.

Age-associated differences in macrophage response in a vaginal wound healing rat model.

INTRODUCTION AND HYPOTHESIS: Surgical treatment of pelvic organ prolapse often includes the use of patients' vaginal connective tissue. Wound healing appears to play an important part in the success of such procedures. The aim of this study was to describe the effect of age on inflammatory processes, specifically macrophage response, involved in vaginal wound healing. METHODS: Twenty-five young (12 weeks old) and 25 old (12 months old) virgin female Fischer rats underwent a standardized 9-mm posterior midline vaginal incision. Tissue samples were taken for histological analysis on days 1, 3, 7, 14 and 30 post-injury. Parameters evaluated included wound area, macrophage number and expression of inflammatory markers including tumor necrosis factor alpha (TNFa), inducible nitric oxide synthase (iNOS), CCR7/CD197, arginase I and CD163/M130. RESULTS: Microscopic examination of the vaginal wounds over time demonstrated a clear difference between young and old rats in spontaneous healing capacity. The average wound area in young rats 1 day after injury was significantly smaller than in old rats (16.5 ± 1.7 vs. 23.8 ± 1.5 mm2, P < 0.05). At 3 days post-injury, wounds were closed in young rats but still open in old rats (wound area: 13.5 ± 1.5 mm2). Old rats demonstrated a more excessive and sustained macrophage response compared with young rats. They also demonstrated a disordered pattern of macrophage expression over time, with a prolonged expression of TNFa and iNOS in the tissue and a disordered M2 macrophage response. CONCLUSION: Excessive and prolonged macrophage response in older rats may contribute to poor wound healing in the vagina.

Intraoperative Vaginal Perforation During Various Mid-Urethral Sling Procedures Treating Female Stress Urinary Incontinence.

BACKGROUND: Incidence of intraoperative vaginal perforation is generally considered to be low but varies among different procedures. Vaginal perforation could not only prolong the surgeries and aggravate surgical trauma but also result in postoperative discomfort or even a second surgery. METHOD: Vaginal perforation, vaginal epithelial perforation, vaginal wall perforation, vaginal penetration, urinary incontinence were searched in PubMed, Cochrane, Embase database to identify the qualified clinical trial and relevant literature sources were also searched. RESULTS: A total of 9223 cases of from 33 trials from literatures and 387 cases from our own trail were analyzed, which provided detailed data on intraoperative vaginal perforation. Incidence of intraoperative vaginal perforation during mid-urethral sling surgery treating stress urinary incontinence was generally low, which was 1.56%. Incidence of intraoperative vaginal perforation during transobturator (TOR) procedure was higher than that during retropubic (RPR) procedure, which were 2.11% and 0.89% respectively. Incidence of intraoperative vaginal perforation during outside-to-inside TOR procedure like TOT and MONARC was higher than that during inside-to-outside TOR procedure like TVT-O, which were 2.74% and 1.52%, respectively. Incidence of intraoperative vaginal perforation during single-incision surgery like H-type TVT-SECUR reached 1.97%, while no report on U-type TVT-SECUR surgeries. CONCLUSION: The incidence of intraoperative vaginal during mid-urethral sling procedures for female stress urinary incontinence is fairly high. Vaginal perforation was more common in trans-obturator route (TOR) than retropubic route (RPR). In TOR route, it was less frequent in inside-to-outside procedure than outside-to-inside procedure. Surgery proficiency could also have an impact on this complication.

Analysis of non-obstetric vaginal and vulvar trauma: risk factors for operative intervention.

Vaginal and vulvar trauma may occur accidentally or because of an act of violence. Due to its rarity, little is known about risk factors effecting need for operative intervention. We sought to perform a large descriptive analysis of adult non-obstetric vulvovaginal trauma (VVT) and elucidate risk factors for requiring operative intervention. A retrospective analysis of the National Trauma Data Bank was performed between 2007 and 2015. Patients ≥ 16 years old with vaginal or vulvar trauma were identified. Risk factors for surgical intervention were identified using a multivariable logistic regression analysis. From 2,040,235 female patients, 2445 (< 0.2%) were identified to have VVT with the majority being injury to the vagina (68.6%). In patients with injury to the vagina, age > 65 (OR = 0.41, CI 0.26-0.62, p < 0.001), Injury Severity Score > 25 (OR = 0.66, CI 0.50-0.86, p = 0.01) and victims of rape (OR = 0.39, 95% CI 0.26-0.57, p < 0.001) were less likely to require operative intervention. In patients with injury to the vulva, age > 65 (OR = 0.45, CI 0.21-0.94, p = 0.02), victims of rape (OR = 0.26, CI 0.08-0.87, p = 0.01) and gunshot violence (OR = 0.10, CI 0.02-0.59, p = 0.02) were less likely to require operative intervention, but those with a concomitant injury to the vagina were more likely to require operative intervention (OR = 2.56, CI 1.63-4.03, p < 0.001). Injuries to the vagina or vulva occur in < 0.2% of traumas. Interestingly, in both vulvar and vaginal trauma, older age, and involvement in rape were associated with lower risk for operative intervention. A combined injury to the vagina and vulva increases the need for operative intervention.

Multiple doses of stem cells maintain urethral function in a model of neuromuscular injury resulting in stress urinary incontinence.

Stress urinary incontinence (SUI) is more prevalent among women who deliver vaginally than women who have had a cesarean section, suggesting that tissue repair after vaginal delivery is insufficient. A single dose of mesenchymal stem cells (MSCs) has been shown to partially restore urethral function in a model of SUI. The aim of the present study was to determine if increasing the number of doses of MSCs improves urethral and pudendal nerve function and anatomy. We hypothesized that increasing the number of MSC doses would accelerate recovery from SUI compared with vehicle treatment. Rats underwent pudendal nerve crush and vaginal distension or a sham injury and were treated intravenously with vehicle or one, two, or three doses of 2 × 106 MSCs at 1 h, 7 days, and 14 days after injury. Urethral leak point pressure testing with simultaneous external urethral sphincter electromyography and pudendal nerve electroneurography were performed 21 days after injury, and the urethrovaginal complex and pudendal nerve were harvested for semiquantitative morphometry of the external urethral sphincter, urethral elastin, and pudendal nerve. Two and three doses of MSCs significantly improved peak pressure; however, a single dose of MSCs did not. Single, as well as repeated, MSC doses improved urethral integrity by restoring urethral connective tissue composition and neuromuscular structures. MSC treatment improved elastogenesis, prevented disruption of the external urethral sphincter, and enhanced pudendal nerve morphology. These results suggest that MSC therapy for postpartum incontinence and SUI can be enhanced with multiple doses.
