Prospective long-term results, complications and risk factors in pelvic organ prolapse treatment with vaginal mesh

Treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries: A scoping review

BACKGROUND

Obstetrical fistula is an abnormal opening between the reproductive tract and lower urinary and/or gastrointestinal tract resulting from obstetrical complications, affecting nearly two million women worldwide. It imposes physical, economic, social, and mental consequences on the affected women. Treatment outcomes vary and, mostly, surgical treatment results in improved quality of life and successful subsequent pregnancy for survivors.

OBJECTIVES

The review aimed to chart and examine the treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries.

SEARCH STRATEGY

This is a scoping review study to identify treatment outcomes of obstetrical fistula surgical repair in low- and middle-income countries. The search was conducted from databases (PUBMED, Embase, CINAHL, Scopus, and Web of Science), and gray literature (Google Scholar, Google, and conference proceedings).

SELECTION CRITERIA

The eligibility criteria were constructed using a participant, concept, and context framework and included study types of primary research, reviews, and reports. Studies without full text and in languages other than English were excluded.

DATA COLLECTION AND ANALYSIS

The relevant characteristics of the included studies were extracted on an Excel spreadsheet and analyzed to chart treatment outcomes.

MAIN FINDINGS

The review examined the full text of 57 studies on the treatment outcomes of obstetrical fistula. The findings were grouped into two themes: early and late outcomes. The early outcomes included incontinence, surgical-site infection, urine retention, hemorrhage, and retained catheter. The late outcomes included fistula recurrence, residual incontinence, quality of life, reproductive issues, mental health, family and social support, and financial status.

CONCLUSION

The treatment outcomes of obstetrical fistula can be grouped into short-term and long-term outcomes. Although this review found adequate studies for the analysis, most study designs were poor. Stronger studies are recommended in the future to guide policy and decision-making. We would like to suggest that researchers conduct systematic reviews and meta-analyses independently for short-term and long-term outcomes.

Subjective and Objective Evaluation of Total Pelvic Floor Reconstruction with Six-Arm Mesh in Patients with Severe Pelvic Organ Prolapse: A 1-Year Retrospective Study

Purpose

To investigate the effect of total pelvic floor reconstruction with a six-arm mesh in the treatment of pelvic organ prolapse.

Patients and Methods

This is a retrospective observational cohort study. A total of 368 patients with pelvic organ prolapse underwent pelvic floor reconstruction surgery. Patients were categorized by the type of surgical mesh: 176 patients received a six-arm mesh and 192 patients received an anteroposterior approach mesh. The 1-year effect of the two groups was compared. The Pelvic Floor Distress Inventory Questionnaire (PFDI-20), Colorectal-Anal Distress Inventory (CRADI-8) and the Pelvic Organ Prolapse Quantitation (POP-Q) staging were used for evaluation. The incidence of complications was recorded. A cure standard was registered by a POP-Q score of grade I or below. A P value <0.05 indicates the difference is statistically significant.

Results

There was no recurrence documented in the patients; the cure rate was 100% in both groups. After surgery, the length of the vagina in the six-arm mesh group was longer than that of the control group at 6 months and 12 months, respectively (P < 0.05). The six-arm mesh group had lower PFDI-20 and CRADI-8 scores after surgery than those of the control group at 6 and 12 months, respectively (P < 0.05). Pelvic floor and rectal dysfunction symptom improvement were superior in the six-arm mesh group compared with the control group. After surgery, the Female Sexual Function Inventory (FSFI) score of the six-arm mesh group was superior to that of the control group at 6 and 12 months, respectively (P < 0.05). The incidence of complications in the six-arm mesh group was lower than that of the control group (P < 0.05).

Conclusion

The total pelvic floor reconstruction using six-arm mesh has the same healing rate as anteroposterior approach mesh surgery, and it is better than traditional surgery in improving subjective symptoms and reducing postoperative complications.

Primary surgical management of anterior pelvic organ prolapse: a systematic review, network meta-analysis and cost-effectiveness analysis

BACKGROUND

Anterior compartment prolapse is the most common pelvic organ prolapse (POP) with a range of surgical treatment options available.

OBJECTIVES

To compare the clinical effectiveness and cost-effectiveness of surgical treatments for the repair of anterior POP.

METHODS

We conducted a systematic review of randomised controlled trials comparing surgical treatments for women with POP. Network meta-analysis was possible for anterior POP, same-site recurrence outcome. A Markov model was used to compare the cost-utility of surgical treatments for the primary repair of anterior POP from a UK National Health Service perspective.

MAIN RESULTS

We identified 27 eligible trials for the network meta-analysis involving eight surgical treatments tested on 3194 women. Synthetic mesh was the most effective in preventing recurrence at the same site. There was no evidence to suggest a difference between synthetic non-absorbable mesh, synthetic partially absorbable mesh, and biological mesh. The cost-utility analysis, which incorporated effectiveness, complications and cost data, found non-mesh repair to have the highest probability of being cost-effective. The conclusions were robust to model inputs including effectiveness, costs and utility values.

CONCLUSIONS

Anterior colporrhaphy augmented with mesh appeared to be cost-ineffective in women requiring primary repair of anterior POP. There is a need for further research on long-term effectiveness and the safety of mesh products to establish their relative cost-effectiveness with a greater certainty.

TWEETABLE ABSTRACT

New study finds mesh cost-ineffective in women with anterior pelvic organ prolapse.

Long-term follow-up of patients treated by transvaginal mesh repair for anterior prolapse

OBJECTIVE

The aim of the study was to assess 5 years outcome of transvaginal single incision mesh surgery (SIMS) for anterior pelvic organ prolapse (POP).

STUDY DESIGN

This was a prospective study including all patients from January 2009 to December 2012 who underwent SIMS for symptomatic anterior prolapse stage ≥2, according to POP Quantification (POP-Q). Symptoms and quality of life were assessed using validated questionnaires: Pelvic Floor Distress Inventory (PFDI-20), Pelvic Floor Impact questionnaire (PFIQ-7), and Prolapse/ Incontinence Sexual Questionnaire (PISQ-12). Main outcome was subjective success (question 3 of PFDI-20 score = 0). Mesh-related complications, objective and functional outcomes were used as the secondary outcomes.

RESULTS

270 patients were included in the study. Median follow-up was 5,7 years [4,5-8,2]. Subjective success rate was 86,6% at 5 years. Objective success rate was 53,1% at 5 years. At 5 years, composite failure (subjective + objective) occurred for 17 patients (12%), 7 patients with direct recurrence and 10 with indirect recurrence. Re-treatment was performed in six patients (2,8%; 3 hysterectomies for apical recurrence and 3 posterior repairs for posterior recurrence). One case (0,4%) of asymptomatic mesh exposure occurred. The reoperation rate for mesh-related complications was 3,4%. At 5 years, de novo dyspareunia rate was 11,7%, 3,9% considered as mesh-related. A significant improvement was noted for symptoms and quality of life.

CONCLUSION

Five-year results demonstrate that vaginal mesh surgery provides a durable and safe repair of anterior compartment prolapse with a low rate of mesh-related complications and reoperations. Between the 2- and 5-year follow-up, patient satisfaction and associated improvements in prolapse-specific symptoms were sustained and minimal new morbidity occurred.

Current trends and future perspectives in pelvic reconstructive surgery

Pelvic organ prolapse is a prevalent disorder with a high lifetime incidence of surgical repair. Pelvic organ prolapse surgery has greatly evolved over the past years, and pelvic floor reconstructive surgeons are faced with a vast array of treatment options for their patients. Our review article illustrates the current trends and future perspectives for the surgical treatment of pelvic organ prolapse.
