Long-term Device Outcomes of Mesh Implants in Pelvic Organ Prolapse Repairs

Development of a coordinated registry network for pelvic organ prolapse technologies

Objectives

The accumulation of data through a prospective, multicenter Coordinated Registry Network (CRN) could be a robust and cost-effective way to gather real-world evidence on the performance of pelvic organ prolapse (POP) technologies for device-based and intervention-based studies. To develop the CRN, a group of POP experts consisting of representatives from professional societies, the Food and Drug Administration, academia, industry, and the patient community, was convened to discuss the role and feasibility of the CRN and to identify the core data elements important to assess POP technologies.

Design

A Delphi method approach was employed to achieve consensus on a core minimum dataset for the CRN. A series of surveys were sent to the panel and answered by each expert anonymously and individually. Results from the surveys were collected, collated, and analyzed by the study design team from Weill Cornell Medicine. Questions for the next round were based on the analysis process and discussed with group members via conference call. This process was repeated twice over a 6-month time period during which consensus was achieved.

Results

Twenty-one experts participated in the effort and proposed 120 data elements. Participation rates in the first and second round of the Delphi survey were 95.2% and 71.4%, respectively. The working group reached final consensus among responders on 90 data elements capturing relevant general medical and surgical history, procedure and discharge, short-term and long-term follow-up, device factors, and surgery and surgeon factors.

Conclusions

The CRN successfully developed a set of core data elements to support the study of POP technologies through convening an expert panel on POP technologies and using the Delphi method. These standardized data elements have the potential to influence patient and provider decisions about treatments and include important outcomes related to efficacy and safety.

The Role of Pessaries in the Treatment of Women With Stress Urinary Incontinence: A Systematic Review and Meta-Analysis

IMPORTANCE

Pessaries are an important conservative therapy for stress urinary incontinence (SUI), but few studies have comprehensively evaluated their utility.

OBJECTIVE

The objective of this study is to evaluate the existing evidence on the efficacy and safety of pessaries for the treatment of SUI.

STUDY DESIGN

We searched for the terms "stress urinary incontinence" and "pessar/y/ies/ium" in PubMed, Embase, and Cinhal on June 10, 2020. Studies that characterized subjective and/or objective data were included. Studies performed in pediatric populations, pregnancy, and use of pessaries not for SUI were excluded. Two reviewers independently screened and assessed data quality and risk of bias according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

RESULTS

Ten studies, including 376 patients, were included. In terms of subjective outcomes, 76% of 72 patients reported feeling continent after pessary treatment compared with 0% of 86 patients surveyed before pessary use (P < 0.0001). Both Urinary Distress Inventory and Incontinence Impact Questionnaire scores decreased significantly by 46.7% (n = 155 baseline, n = 139 follow-up; P < 0.0001) and 67.8% (n = 139 baseline, n = 107 follow-up; P < 0.0001), respectively. Significant objective measures associated with pessary use included increased urethral closure pressure (n = 122; g = 0.56; 95% confidence interval [CI], -0.66 to 1.77; P < 0.049) and decreased pad weight (n = 129 baseline; n = 118 follow-up; g = -0.89; 95% CI, -1.986 to 0.19; P = 0.009). Adverse events significantly decreased at greater than 6 months follow-up compared with less than 6 months follow-up, including pain (31.5%, n = 29/92 vs 14.3%, n = 5/35; P = 0.0513) and discomfort (50%, n = 46/92 vs 29.3%, n = 12/41; P = 0.0268).

CONCLUSIONS

Based on both subjective and objective measures, pessaries are an effective conservative treatment option for SUI. This supports pessary use, though larger studies with longer-term follow-up are warranted.

Development and Usability Testing of a Mobile Application to Monitor Patient-Reported Outcomes after Stress Urinary Incontinence Surgery

OBJECTIVE

To develop and perform a usability testing of a mobile application (app) with representative users of surgeons and female patients undergoing stress urinary incontinence (SUI) surgery.

METHODS

A mobile app was developed with the Medical Device Epidemiology Network (MDEpiNet) High-Performance Integrated Virtual Environment (HIVE) to streamline the collection of patient-reported outcomes following SUI surgery using validated questionnaires. It was designed as a collaborative effort with the Women's Health Initiative (WHI), including patient and surgeon involvement. The app evaluation questions addressed the user's rating on the clarity and length of the questions and the comfort level in using the interface for patients to report post-operative outcomes and surgeons to review them.

RESULTS

A total of twenty patients and 5 surgeons tested the mobile app and reported their experience and level of satisfaction. The average patient experience score was 9 out of ten, with ten being the best. Eleven patients (55%) were interested in replacing in-person follow-up visits with the app. The surgeons reported an average user experience score of 8.6 out of ten. Four surgeons (80%) were interested in replacing in-person visits with the app. The combined experience score between all users was 8.9 out of ten. Fifteen out of twenty-five users (60%) showed interest in replacing in-person visits with the app.

CONCLUSION

The mobile app for SUI captured important patient-reported outcomes with a high satisfaction reporting from patients and surgeons.

Long-term outcomes of transvaginal mesh surgery for pelvic organ prolapse: a retrospective cohort study

Background

The objective of this study was to evaluate the overall outcomes and complications of transvaginal mesh (TVM) placement for the management of pelvic organ prolapse (POP) with different meshes with a greater than 10-years of follow-up.

Methods

We performed a retrospective review of patients with POP who underwent prolapse repair surgery with placement of transvaginal mesh (Prolift kit or self-cut Gynemesh) between January 2005 and December 2010. Baseline of patient characteristics were collected from the patients’ medical records. During follow-up, the anatomical outcomes were evaluated using the POP Quantification system, and the Patient Global Impression of Improvement (PGI-I) was used to assess the response of a condition to therapy. Overall postoperative satisfaction was assessed by the following question: “What is your overall postoperative satisfaction, on a scale from 0 to 10?”. Relapse-free survival was analyzed using Kaplan–Meier curves.

Results

In total, 134 patients were included. With a median 12-year (range 10–15) follow-up, 52 patients (38.8%) underwent TVM surgery with Prolift, and Gynemesh was used 82 (61.2%). 91% patients felt that POP symptom improved based on the PGI-I scores, and most satisfied after operation. The recurrence rates of anterior, apical and posterior compartment prolapse were 5.2%, 5.2%, and 2.2%, respectively. No significant differences in POP recurrence, mesh-associated complications and urinary incontinence were noted between TVM surgery with Prolift versus Gynemesh.

Conclusions

Treatment of POP by TVM surgery exhibited long-term effectiveness with acceptable morbidity. The outcomes of the mesh kit were the same as those for self-cutmesh.

Exosome-Induced Vaginal Tissue Regeneration in a Porcine Mesh Exposure Model

OBJECTIVES

The purpose of this study was to explore the utility of an injectable purified exosome product derived from human apheresis blood to (1) augment surgical closure of vaginal mesh exposures, and (2) serve as a stand-alone therapy for vaginal mesh exposure.

METHODS

Sixteen polypropylene meshes (1×1-3×3 cm) were implanted in the vaginas of 7 Yorkshire-crossed pigs by urogynecologic surgeons (day 0). On day 7, group 1 underwent surgical intervention via vaginal tissue suture reclosure with (n=2 pigs, n=4 meshes) or without (n=2 pigs, n=4 meshes) exosome injection; group 2 underwent medical intervention with an exosome injection (n=3, n=8 meshes). One animal in group 2 was given oral 2'-deoxy-5-ethynyluridine to track cellular regeneration. Euthansia occurred at 5 weeks.

RESULTS

Mesh exposures treated with surgical closure alone experienced reexposure of the mesh. Exosome treatment with or without surgical closure resulted in partial to full mesh exposure resolution up to 3×3 cm. Exosome-treated tissues had significantly thicker regenerated epithelial tissue (208 μm exosomes-only and 217 μm surgery+exosomes, versus 80 μm for surgery-only; P < 0.05); evaluation of 2'-deoxy-5-ethynyluridine confirmed de novo regeneration throughout the epithelium and underlying tissues. Capillary density was significantly higher in the surgery+exosomes group (P = 0.03). Surgery-only tissues had a higher inflammatory and fibrosis response as compared with exosome-treated tissues.

CONCLUSIONS

In this pilot study, exosome treatment augmented healing in the setting of vaginal mesh exposure, reducing the incidence of mesh reexposure after suture closure and decreasing the area of mesh exposure through de novo tissue regeneration after exosome injection only. Further study of varied local tissue conditions and mesh configurations is warranted.

Management of Vaginal Mesh Exposures Following Female Pelvic Reconstructive Surgery

PURPOSE OF REVIEW

To discuss considerations and current evidence for the diagnosis and management of vaginal mesh exposures following female mesh-augmented anti-incontinence and pelvic organ prolapse surgery.

RECENT FINDINGS

Since the introduction of mesh into female pelvic surgery, various applications have been reported, each with their own unique risk profile. The most commonly encountered mesh-related complication is vaginal mesh exposure. Current evidence on the management of vaginal mesh exposure is largely limited to observational studies and case series, though this is continuing to expand. We present a synthesis of the available data, as well as clinical and surgical approaches to managing this complication. It is important for surgeons to be familiar with the management of vaginal mesh exposures. Depending on the patient's presentation and goals, there is a role for conservative measures, mesh revision, or mesh excision. Further study is warranted to standardize mesh resection techniques and explore non-surgical treatments.
