Vaginal Cuff Dehiscence and Small Intestinal Prolapse in a Middle-Aged Woman Due to Ring Pessary Use

Objective

Vaginal cuff rupture is a rare but serious postoperative complication predominantly occurring after hysterectomy. Given that it can lead to partial or total evisceration, bowel strangulation, sepsis, and acute mesenteric ischemia. Any instance of this complication should be treated as a surgical emergency. In this context, we report a case of a vaginal stump following regular use of pessaries.

Case Report

A 50-year-old woman was admitted to the hospital with sudden onset of bowel-like prolapse from the vagina. She had a 7-year history of vaginal prolapse and had previously undergone repair surgery and laparoscopic hysterectomy for uterine fibroids. Following her hysterectomy, she began using a pessary due to recurrent prolapse. Clinical assessment revealed vaginal evisceration of the intestines, necessitating emergency surgery. She was discharged smoothly on the eighth day post-operation. Three months later, she underwent a laparoscopic sacrocolpopexy.

Conclusion

The utilization of pessaries may heighten the risk of stump rupture in patients following hysterectomy, thereby demanding more vigilant attention from gynecologists.

'I have no life and neither do the ones watching me suffer': women's experiences of transvaginal mesh implant surgery

Objective: Many women are affected by pelvic floor disorders, such as stress urinary incontinence and pelvic organ prolapse. In recent years, these disorders have been treated with transvaginal mesh implant surgeries involving the vaginal insertion of woven netting. We explored women's experiences of transvaginal mesh implant surgery through a biopsychosocial lens. Design: We analysed women's submissions to an Australian Parliament Senate Inquiry on transvaginal mesh implant surgery using thematic analysis. Main Outcome Methods: One-hundred and fifty-three publicly available submissions detailing women's experiences of transvaginal mesh implant surgery to an Australian Parliament Senate Inquiry were analysed. Adverse and positive accounts were eligible for inclusion. Results: We generated nine themes in three categories relating to the Biopsychosocial Model: Physical Health - comprising three themes; Psychological Health - comprising two themes; and Social Wellbeing - comprising four themes. Physical, psychological and social experiences interacted, resulting in reduced quality of life for women. Conclusion: Most women who made submissions to an Australian government inquiry about transvaginal mesh implant surgery described devastating impacts on physical, psychological, and social wellbeing. We provide recommendations to guide psychologists in assisting women with adverse transvaginal mesh-related outcomes. Further research should explore women's long-term experiences of the various transvaginal mesh procedures.

Pelvic Floor Dysfunction among Reproductive-Age Women in Israel: Prevalence and Attitudes-A Cross-Sectional Study

Objectives: Our study aimed to investigate the prevalence of female pelvic floor dysfunction (PFD) in Israeli women who experienced vaginal delivery and are in their reproductive years (premenopausal), as well as to understand their attitudes and health-seeking behavior and barriers towards treating this problem. Methods: In this cross-sectional study, we conducted a questionnaire-based Internet survey. The surveys were sent to Israeli women in their fertile years (18-50 years old). We asked the women about their PFD symptoms, attitudes, and help-seeking behaviors. We used two validated questionnaires, including the USIQ and the PFDI-20. The combined questionnaire was submitted in both Hebrew and Arabic. We assessed the prevalence of PFD symptoms in the study population. Symptomatic women were asked about their help-seeking behaviors and their beliefs, desires, and barriers regarding the clinical management of symptoms. Results: Between July and September 2020, 524 women completed the questionnaire (response rate 44%). In total, 95% reported at least one symptom (mostly urinary-related) at any grade of severeness in at least one category, and 66.8% suffered from at least one moderate to severe symptom in at least one category. Most women (93.7%) reported that they wanted to be asked and offered voluntary information about PFD from physicians and nurses; however, only 16.6% reported receiving such information. Barriers to seeking treatment were mainly related to low awareness. The study's main limitation was selection bias due to the questionnaire's design. Conclusions: These findings show the importance of raising awareness of the different therapeutic solutions to PFD symptoms and designing more available services for this common problem.

Patients' perspectives about doctor-patient communication regarding transvaginal mesh implant surgery

OBJECTIVES

Many women experience pelvic floor disorders which may require medical intervention such as transvaginal mesh implant surgeries (TVM; the abdominal or vaginal insertion of woven netting to support pelvic tissue). We examined women's perceptions of communication with their health professionals concerning TVM.

DESIGN

We analysed 153 women's written submissions to an Australian Government Inquiry regarding their experiences of transvaginal mesh surgery to explore their perceptions of TVM-related doctor-patient communication. Data were analysed using deductive and inductive reflexive thematic analysis.

RESULTS

Women expressed several challenges in their communication with their health professionals. Three themes regarding communication were generated: Insufficient information was abundant; Normalisation and minimisation of the procedure and risks; and, Desired communication interactions.

CONCLUSIONS

According to women's accounts, doctor-patient communication was poor. Health professionals must be knowledgeable about medical procedures and their potential complications and provide their patients with adequate, accurate information to make informed choices about their health. Health professionals should also document informed consent.

PRACTICE IMPLICATIONS

Health professionals should be well-informed about TVM, including best-practice treatments for pelvic floor disorders, indications for TVM, the risks, outcomes and potential complications from various forms of TVM, and ways to adequately communicate sufficient information to women.

Development of 3D Printed Biodegradable Mesh with Antimicrobial Properties for Pelvic Organ Prolapse

To address the increasing demand for safe and effective treatment options for pelvic organ prolapse (POP) due to the worldwide ban of the traditional polypropylene meshes, this study introduced degradable polycaprolactone (PCL)/polyethylene glycol (PEG) composite meshes fabricated with melt-electrowriting (MEW). Two PCL/PEG mesh groups: 90:10 and 75:25 (PCL:PEG, wt%) were fabricated and characterized for their degradation rate and mechanical properties, with PCL meshes used as a control. The PCL/PEG composites showed controllable degradation rates by adjusting the PEG content and produced mechanical properties, such as maximal forces, that were higher than PCL alone. The antibacterial properties of the meshes were elicited by coating them with a commonly used antibiotic: azithromycin. Two dosage levels were used for the coating: 0.5 mg and 1 mg per mesh, and both dosage levels were found to be effective in suppressing the growth of S. aureus bacteria. The biocompatibility of the meshes was assessed using human immortalized adipose derived mesenchymal stem cells (hMSC). In vitro assays were used to assess the cell viability (LIVE/DEAD assay), cell metabolic activity (alamarBlue assay) and cell morphology on the meshes (fluorescent and electron microscopy). The cell attachment was found to decrease with increased PEG content. The freshly drug-coated meshes showed signs of cytotoxicity during the cell study process. However, when pre-released for 14 days in phosphate buffered saline, the initial delay in cell attachment on the drug-coated mesh groups showed full recovery at the 14-day cell culture time point. These results indicated that the PCL/PEG meshes with antibiotics coating will be an effective anti-infectious device when first implanted into the patients, and, after about 2 weeks of drug release, the mesh will be supporting cell attachment and proliferation. These meshes demonstrated a potential effective treatment option for POP that may circumvent the issues related to the traditional polypropylene meshes.

Biologic Grafts for Use in Pelvic Organ Prolapse Surgery: a Contemporary Review

PURPOSE OF REVIEW

Pelvic organ prolapse (POP) is a common condition and there is a plethora of surgical techniques available to address this problem. We present a review of biologic grafts, including the latest literature to help guide a surgeon's choice on the type of biologic materials to augment repairs.

RECENT FINDINGS

Since the 2019 Food and Drug Administration (FDA) ban on mesh, including xenograft, there is a sparsity of biologic graft products available for POP repairs. This has led to a significant decrease in surgical application. Surgeons must be familiar with the biochemical properties, processing, and clinical application of biologic grafts prior to use. They should also be familiar with alternative operative techniques that utilize autografts, although there is limited outcome data on these techniques. With heightened awareness of mesh and its complications, biologic grafts have made a resurgence. Surgeons must be well versed on their available options. Current literature is limited, and studies have not demonstrated superiority of biologic graft over native tissue repairs for prolapse. Nevertheless, there is a role for these types of biologic graft material in specific patient populations. Future studies are warranted.

Development of a core data set for pelvic floor disorder patients registry

OBJECTIVES

Pelvic floor disorders (PFDs) are important public health concerns due to their increasing prevalence. Hence, there is an increasing need for developing systematically collected quality data to assist appropriate clinical decision-making. This study aimed to develop a core data set for patients with PFDs based on the PFDs registry.

METHODS

A descriptive cross-sectional study was conducted in 2019. Data were retrieved from electronic databases including PubMed, Embase and Google scholar. Available documents and data systems in clinical centers were also assessed. The Delphi technique was applied to reach a consensus about the data elements using a questionnaire. A panel of experts evaluated the content validity of the questionnaire.

RESULTS

We developed a dataset for PFDs that included two classes of data (65 data items) identified from the related literature. In the Delphi survey, 74 data elements were determined by the experts and final data were divided into two demographic and clinical categories that included 12 and 62 data elements, respectively.

CONCLUSIONS

This dataset has the potential for standardizing the data by providing accurate, consistent, complete and uniform data elements. Furthermore, it can provide valuable research facilities for clinicians and researchers in the healthcare system resulting in improvement of the quality of care and containment of costs.

Bioengineering in women's health: part I

This theme issue of Interface Focus is the first of two sets of articles on the topic of bioengineering in women's health. Although there is a long history of collaboration between engineers and medical professionals in orthopaedics and cardiovascular medicine, there has been growing interest in the last decade for interdisciplinary collaborations in other areas of medical science. This growth is particularly true in the case of women's health, a traditionally underserved area of research in the scientific community where fundamental knowledge of female physiology is still needed. Women's health is a broad category encompassing reproduction, fertility, maternal health, normal and abnormal pregnancy and the sequelae associated with a difficult childbirth. Women's health also includes sex-associated pathology associated with cancer, pain, cardiac disease, osteoporosis and other diseases. This list is not exhaustive with new scientific frontiers developing based on the evolving discourse of medicine for all. This first issue in the series focuses on bioengineering advances in the study of the non-pregnant woman, and the articles highlight important developments in pelvic floor disorders, biomedical devices, fertility, breast implant failure and breast cancer. The second issue in the series focuses on pregnancy.
