Enabling Technologies for Gynecologic Vaginal Surgery: A Systematic Review.

OBJECTIVE: To systematically review the literature to evaluate clinical and surgical outcomes for technologies that facilitate vaginal surgical procedures. DATA SOURCES: We systematically searched MEDLINE, EMBASE, and ClinicalTrials.gov from January 1990 to May 2022. METHODS OF STUDY SELECTION: Comparative and single-arm studies with data on contemporary tools or technologies facilitating intraoperative performance of vaginal gynecologic surgical procedures for benign indications were included. Citations were independently double screened, and eligible full-text articles were extracted by two reviewers. Data collected included study characteristics, technology, patient demographics, and intraoperative and postoperative outcomes. Risk of bias for comparative studies was assessed using established methods, and restricted maximum likelihood model meta-analyses were conducted as indicated. TABULATION, INTEGRATION, AND RESULTS: The search yielded 8,658 abstracts, with 116 eligible studies that evaluated pedicle sealing devices (n=32), nonrobotic and robotic vaginal natural orifice transluminal endoscopic surgery (n=64), suture capture devices (n=17), loop ligatures (n=2), and table-mounted telescopic cameras (n=1). Based on 19 comparative studies, pedicle sealing devices lowered vaginal hysterectomy operative time by 15.9 minutes (95% CI, -23.3 to -85), blood loss by 36.9 mL (95% CI, -56.9 to -17.0), hospital stay by 0.2 days (95% CI, -0.4 to -0.1), and visual analog scale pain scores by 1.4 points on a subjective 10-point scale (95% CI, -1.7 to -1.1). Three nonrandomized comparative studies and 53 single-arm studies supported the feasibility of nonrobotic vaginal natural orifice transluminal endoscopic surgery for hysterectomy, adnexal surgery, pelvic reconstruction, and myomectomy. Data were limited for robotic vaginal natural orifice transluminal endoscopic surgery, suture capture devices, loop ligatures, and table-mounted cameras due to few studies or study heterogeneity. CONCLUSION: Pedicle sealing devices lower operative time and blood loss for vaginal hysterectomy, with modest reductions in hospital stay and pain scores. Although other technologies identified in the literature may have potential to facilitate vaginal surgical procedures and improve outcomes, additional comparative effectiveness research is needed.

Repair of Vesicovaginal Fistulae: A Systematic Review.

OBJECTIVE: To assess and compile the current level of evidence regarding successful surgical treatment of vesicovaginal fistulae and how these perioperative interventions affect anatomic, patient-centered, and adverse outcomes. DATA SOURCES: PubMed and EMBASE were searched from inception through September 9, 2022. METHODS OF STUDY SELECTION: This review included comparative studies (of any sample size) and single-group studies (1,000 or more participants) of primary or recurrent vesicovaginal fistula (ie, vesicovaginal fistula, urethrovaginal fistula, and bladder neck-vaginal fistula). We evaluated preintervention assessment or management, various techniques for intraoperative management, and postoperative management. Outcomes of interest included anatomic and objective outcomes (such as successful repair, fistula closure, urinary incontinence, recurrent fistula, perioperative complications) and subjective outcomes (such as voiding symptoms and quality of life). Abstracts and full-text articles were screened in duplicate, and study descriptions and findings were extracted into standardized extraction forms. Risk of bias was assessed independently by two investigators and adjudicated by a third. Study quality was summarized with standardized tools. We conducted random-effects model and restricted maximum-likelihood meta-analyses of relative risks when at least three studies compared similar interventions and reported similar outcome measures. TABULATION, INTEGRATION, AND RESULTS: Forty-six studies met the inclusion criteria. Studies were categorized into 11 domains: 1) preoperative assessment, 2) preoperative and postoperative physical therapy, 3) route of surgery, 4) incorporation of a flap, 5) trimming, 6) layered closure, 7) intraoperative antibiotics, 8) fibrin glue, 9) fascial sling, 10) postoperative Foley catheter duration, and 11) quality of life. Although the strength of the data is insufficient, preoperative phenazopyridine, physical therapy, layered closure, and intraoperative antibiotics seemed to improve the rate of successful fistula repair. Route of surgery (vaginal vs abdominal laparotomy) was determined primarily by surgeon preference and showed no difference in successful fistula repair. In addition, use of interpositional flaps, trimming fistula edges, fibrin glue, and fascial sling did not show significant improvement in rates of fistula cure. Overall, quality-of-life scores improved postoperatively regardless of route of repair and use of interpositional flaps. CONCLUSION: Our findings highlight the limited information available to guide evidence-based treatment of vesicovaginal fistula repair. Overall, high-quality evidence is lacking to provide guidelines; therefore, expert opinion remains the primary influence for fistula repair recommendations.

Foley Balloon Pull Test of Pelvic Floor Muscle Strength.

IMPORTANCE: Methods for pelvic floor muscle (PFM) strength testing are limited by their subjective nature, prohibitive cost, training burden, or lack of validation. OBJECTIVES: The objectives of this study are to validate a new, inexpensive, and accessible method for PFM strength testing using a 30-mL Foley balloon inserted into the vagina, the Foley Balloon Pull Test (FPT), and to demonstrate external validity by comparing the subjective Oxford Muscle Grading Scale (OMGS) scores to measurements obtained with the FPT. Secondary objectives include demonstrating repeatability and internal validity of the FPT. STUDY DESIGN: Participants underwent PFM strength testing with the OMGS on a 0 to 5 scale. A gauge was attached to the Foley balloon to measure the force required to remove the balloon from the vagina. Three measures at rest and 3 measures during maximal muscle contraction were recorded. Cross-sectional data were analyzed. RESULTS: One hundred one participants were included; there were no adverse events. The ratio of contraction FPT measurements to at-rest measurements revealed moderate linear and rank order correlation with the OMGS ( R2 = 0.54, P < 0.001, and R2 = 0.58, P < 0.001). The reliability of repeated measurements was highly correlated, with intraclass correlation coefficients >0.95. An FPT ratio of 1.75 discriminated between weak (0-2) and strong (3-5) OMGS scores with an area under the curve of 0.86. CONCLUSION: The FPT is an internally reliable, simple, and externally valid method of PFM strength testing.

A Summary of Female Genital Mutilation/Cutting for the Pediatric and Adolescent Care Provider.

The World Health Organization defines female genital mutilation/cutting as any medically unnecessary procedure involving partial or total removal of the external female genitalia or other injury to the female genital organs. It is a violation of human rights and associated with serious complications and lifelong impact on health. This review article summarizes for the pediatric and adolescent care provider the incidence worldwide, the impact of cultural practices, appropriate screening and diagnosis, interventions, and treatment, along with legal and ethical issues.

Pelvic Floor Disorders/Obstetric Fistula.

Pelvic floor disorders (PFDs) and obstetric fistula (OF) are common across the globe. PFDs include stress and urge urinary incontinence, overactive bladder, pelvic organ prolapse, fecal incontinence, sexual dysfunction, and pelvic pain. Although PFD and OF are common in low- and middle-income countries (LMIC) there is a lack of awareness and constraints in health care resources. This article focuses on epidemiology, risk factors, assessment, and treatment of PFD and OF in resource-poor settings. Adherence to basic medical ethics principles has to be maintained at all times, coupled with knowledge of and respect for local cultures, traditions, and perceptions of health norms.

Return to urinary continence and sexual function after pelvic fracture-urethral injury - A young woman's years-long journey.

Pelvic fracture urethral injury (PFUI) is a rare condition that can have severe short and long-term consequences. Though it is rare, it is essential to consider this diagnosis with a high index of suspicion in the setting of pelvic trauma. With appropriate management, patients may have a successful return to normal urinary and sexual functions even after devastating injury and urethral obliteration.

Surgical Removal of Midurethral Sling in Women Undergoing Surgery for Presumed Mesh-Related Complications: A Systematic Review.

OBJECTIVE: To assess whether some, or all, of the mesh needs to be removed when a midurethral sling is removed for complications. DATA SOURCES: A systematic review and meta-analysis was conducted. MEDLINE, Cochrane, and ClinicalTrials.gov databases from January 1, 1996, through May 1, 2021, were searched for articles that met the eligibility criteria with total, partial, or a combination of anti-incontinence mesh removal. METHODS OF STUDY SELECTION: All study designs were included (N≥10), and a priori criteria were used for acceptance standards. Studies were extracted for demographics, operative outcomes, and adverse events. Meta-analysis was performed when possible. TABULATION, INTEGRATION, AND RESULTS: We double-screened 11,887 abstracts; 45 eligible and unique studies were identified. Thirty-five were single-group studies that evaluated partial mesh removal, five were single-group studies that evaluated total mesh removal, and five were studies that compared partial mesh removal with total mesh removal. All of the studies were retrospective in nature; there were no randomized controlled studies. Comparative studies demonstrated that partial mesh removal had lower rates of postoperative stress urinary incontinence (SUI) than total mesh removal (odds ratio 0.46, 95% CI 0.22-0.96). Single-group studies supported lower rates of postoperative SUI with partial mesh removal compared with total mesh removal (19.2% [95% CI 13.5-25.7] vs 48.7% [95% CI 31.2-66.4]). Both methods were similar with respect to associated pain, bladder outlet obstruction, mesh erosion or exposure, and lower urinary tract symptoms. Adverse events were infrequent. CONCLUSION: Postoperative SUI may be lower with partial mesh removal compared with total mesh removal. Other outcomes were similar regardless of the amount of mesh removed.

Recommended standardized anatomic terminology of the posterior female pelvis and vulva based on a structured medical literature review.

BACKGROUND: Anatomic terminology in both written and verbal forms has been shown to be inaccurate and imprecise. OBJECTIVE: Here, we aimed to (1) review published anatomic terminology as it relates to the posterior female pelvis, posterior vagina, and vulva; (2) compare these terms to "Terminologia Anatomica," the internationally standardized terminology; and (3) compile standardized anatomic terms for improved communication and understanding. STUDY DESIGN: From inception of the study to April 6, 2018, MEDLINE database was used to search for 40 terms relevant to the posterior female pelvis and vulvar anatomy. Furthermore, 11 investigators reviewed identified abstracts and selected those reporting on posterior female pelvic and vulvar anatomy for full-text review. In addition, 11 textbook chapters were included in the study. Definitions of all pertinent anatomic terms were extracted for review. RESULTS: Overall, 486 anatomic terms were identified describing the vulva and posterior female pelvic anatomy, including the posterior vagina. "Terminologia Anatomica" has previously accepted 186 of these terms. Based on this literature review, we proposed the adoption of 11 new standardized anatomic terms, including 6 regional terms (anal sphincter complex, anorectum, genital-crural fold, interlabial sulcus, posterior vaginal compartment, and sacrospinous-coccygeus complex), 4 structural terms (greater vestibular duct, anal cushions, nerve to the levator ani, and labial fat pad), and 1 anatomic space (deep postanal space). In addition, the currently accepted term rectovaginal fascia or septum was identified as controversial and requires further research and definition before continued acceptance or rejection in medical communication. CONCLUSION: This study highlighted the variability in the anatomic nomenclature used in describing the posterior female pelvis and vulva. Therefore, we recommended the use of standardized terminology to improve communication and education across medical and anatomic disciplines.

The INSPIRE Comparative Cost Study: 12-Month Health Economic and Clinical Outcomes Associated with Hysterectomy, Myomectomy, and Treatment with the Sonata System.

PURPOSE: The INSPIRE study compared perioperative and 12-month health economic and clinical outcomes associated with hysterectomy, myomectomy, and sonography-guided transcervical fibroid ablation (TFA) using the Sonata® system. PATIENTS AND METHODS: Cost and health care resource utilization (HCRU) data for TFA were obtained from a prospective, multicenter, single-arm clinical trial. Data for hysterectomy and myomectomy arms were derived from the Truven Health MarketScan commercial payer claims database. The Truven data was used to determine health economic outcomes and costs for the hysterectomy and myomectomy arms. For each arm, payer perspective costs were estimated from the available charge and HCRU data. RESULTS: TFA with Sonata had significantly lower mean length of stay (LOS) of 5 hrs versus hysterectomy (73 hrs) or myomectomy (79 hrs; all p< 0.001). The average payer cost for TFA treatment, including the associated postoperative HCRU was $8,941. This was significantly lower compared to hysterectomy ($24,156) and myomectomy ($22,784; all p< 0.001). In the TFA arm, there were no device- or procedure-related costs associated with complications during the peri- or postoperative time frame. TFA subjects had significantly lower costs associated with complications, prescription medications, and radiology. CONCLUSION: Compared to hysterectomy and myomectomy, TFA treatment with the Sonata system was associated with significantly lower index procedure cost, complication cost, and LOS, contributing to a lower total payer cost through 12 months.

Standardized terminology of apical structures in the female pelvis based on a structured medical literature review.

The objectives of this study were to review the published literature and selected textbooks, to compare existing usage to that in Terminologia Anatomica, and to compile standardized anatomic nomenclature for the apical structures of the female pelvis. MEDLINE was searched from inception until May 30, 2017, based on 33 search terms generated by group consensus. Resulting abstracts were screened by 11 reviewers to identify pertinent studies reporting on apical female pelvic anatomy. Following additional focused screening for rarer terms and selective representative random sampling of the literature for common terms, accepted full-text manuscripts and relevant textbook chapters were extracted for anatomic terms related to apical structures. From an initial total of 55,448 abstracts, 193 eligible studies were identified for extraction, to which 14 chapters from 9 textbooks were added. In all, 293 separate structural terms were identified, of which 184 had Terminologia Anatomica-accepted terms. Inclusion of several widely used regional terms (vaginal apex, adnexa, cervico-vaginal junction, uretero-vesical junction, and apical segment), structural terms (vesicouterine ligament, paracolpium, mesoteres, mesoureter, ovarian venous plexus, and artery to the round ligament) and spaces (vesicocervical, vesicovaginal, presacral, and pararectal) not included in Terminologia Anatomica is proposed. Furthermore, 2 controversial terms (lower uterine segment and supravaginal septum) were identified that require additional research to support or refute continued use in medical communication. This study confirms and identifies inconsistencies and gaps in the nomenclature of apical structures of the female pelvis. Standardized terminology should be used when describing apical female pelvic structures to facilitate communication and to promote consistency among multiple academic, clinical, and surgical disciplines.

Advances in the management of endometriosis in the adolescent.

PURPOSE OF REVIEW: The present article provides an overview of the molecular mechanisms underlying adolescent endometriosis and advances in both medical and surgical management. RECENT FINDINGS: Molecular and cellular features of endometriotic lesions differ from eutopic endometrium. There is altered estrogen-mediated cell signaling, proinflammatory pathways develop in the local microenvironment, along with impaired cellular immunity and growth factors, cytokines, and angiogenic factors play a critical role. This leads to proliferation and invasion by ectopic endometrial tissue, and natural clearance by the immune system fails. The inflammation, scarring, and adhesions are symptomatically expressed as dysmenorrhea, pelvic pain, and dyspareunia significantly compromising quality of life.In adolescence, there is a significant delay in diagnosis, often because of physician nonresponsiveness. The social, emotional, and physical impact on adolescents is underestimated. Medical management aimed at cessation of menses is paramount, if surgical management is needed, the goal is maximal excision. A variety of new medications, including GnRH and progesterone antagonists, selective estrogen and progesterone receptor modulators, aromatase inhibitors, statins, angiogenic inhibitors, and botanicals represent future treatment options. SUMMARY: Early diagnosis of adolescent endometriosis is critical. An understanding of the complex proinflammatory pathways underlying its progression and tailored medical-surgical treatment offers the greatest potential to decrease disease symptomatology.

Competency-Based Objectives in Global Underserved Women's Health for Medical Trainees.

The Association of Professors of Gynecology and Obstetrics Committee on Global Health developed an inclusive definition of global women's health and competency-based objectives that reflected work internationally, as well as with U.S. vulnerable and underserved populations, such as refugee and immigrant populations or those who would otherwise have compromised access to health care. The knowledge, skill, and attitude-based competencies required to fulfill each learning objective were mapped to the Accreditation Council for Graduate Medical Education Outcomes Project's educational domains and the Consortium of Universities for Global Health competency domains. The proposed global women's health definition and competency-based learning objective framework is a first step in ensuring quality standards for educating trainees to address global women's health needs. By proposing these objectives, we hope to guide future program development and spark a broader conversation that will improve health for vulnerable women and shape educational, ethical, and equitable global health experiences for medical trainees.

Surgical treatment of persistent vaginal granulation tissue using CO(2) laser vaporization under colposcopic and laparoscopic guidance.

INTRODUCTION: There have been many reports in the literature on vaginal mesh erosion as a complication of pelvic floor reconstructive surgery. Several reports describe successful surgical excision of the exposed mesh as a resolution. However, in rare cases of mesh erosion, poor surgical outcomes and multiple resection failures have been reported. We describe an innovative surgical approach to persistent vaginal mesh erosion using CO(2) laser vaporization under colposcopic and laparoscopic guidance. CASE DESCRIPTION: A 58-y-old postmenopausal woman first presented with a 3-y history of vaginal discharge and spotting after undergoing a Mentor ObTape transobturator sling (Mentor Corp, Santa Barbara, CA), for the treatment of stress urinary incontinence. Despite surgical removal of the mesh and multiple attempts at cauterization of persistent granulation tissue, her symptoms persisted. DISCUSSION: Using a CO(2) laser under colposcopic and laparoscopic guidance, we were able to safely expose and remove the remaining portion of retained mesh. To our knowledge, this is the first report describing CO(2) laser vaporization as a surgical approach for the successful treatment of recurrent mesh erosion.
