Pelvic organ prolapse management

Surgical management practice of pelvic organ prolapse among Ethiopian gynecologists, 2021: a descriptive study

INTRODUCTION

Pelvic Organ Prolapse is the descent of one or more of the anterior vaginal wall, posterior vaginal wall, the uterus, or the apex of the vagina. Surgical intervention addresses both anatomical defect and associated symptoms. The landscape of prolapse surgery has been evolving constantly over years. Emerging evidences either support or challenge existing surgical treatment options, making urogynecology a dynamic field. In Ethiopia, the surgical management of pelvic organ prolapse has transitioned from abdominal to vaginal hysterectomy, supplemented later by McCall's culdoplasty. Disparities exist in the national uniformity of surgical approaches, linked to the establishment of Urogynecology centers in certain institutions.

OBJECTIVES

This study was done to assess the surgical management practice of Ethiopian gynecologists on pelvic organ prolapse.

METHODS

A cross-sectional study encompassing all Gynecologists in Ethiopia took place between January to June 2021. Information was gathered through online Google forms crafted in English. Subsequently, the collected data underwent verification, coding, and entry into Epi info 7 before being exported to SPSS version 22 software for descriptive statistical analysis.

RESULTS

We reached 280 gynecologists out of the 450 practicing in the Ethiopia making 62% response rate. Anterior colporrhaphy (98.6%), vaginal hysterectomy with McCall's cul-do-plasty (51.8%), and Posterior colporrhaphy (97.5%) were the most commonly performed surgical procedures for anterior vaginal wall prolapse, apical prolapse (uterine/cervical), and posterior vaginal wall prolapse respectively. Only 3.2% and 0.7% of the gynecologists conducted abdominal and vaginal paravaginal repair for anterior vaginal wall prolapse. Sacrospinous ligament fixation and sacrocolpopexy for apical prolapse were carried out by 32.9% and 9.3% of the gynecologists respectively. Site-specific posterior repair for posterior vaginal wall prolapse was performed only by 23.9% of the gynecologists. The main reasons mentioned not to perform paravaginal repair, sacrocolpopexy, sacrospinous ligament fixation, and site-specific posterior repair were lack of skill and lack of appropriate materials.

CONCLUSION AND RECOMMENDATION

Most gynecologists in Ethiopian continue to perform vaginal hysterectomy and colporrhaphy procedures for treatment of pelvic organ prolapse due primarily to lack of skill and appropriate materials to perform the alternative procedures. Implementing short term training on alternative surgical treatment options of pelvic organ prolapse with provision of suitable materials and increasing the number of urogynecologists in the country in the long run holds the potential to enhance the standard of care of women with the condition.

Immunobiology of foreign body response to composite PLACL/gelatin electrospun nanofiber meshes with mesenchymal stem/stromal cells in a mouse model: Implications in pelvic floor tissue engineering and regeneration

Pelvic Organ Prolapse (POP) is a common gynaecological disorder where pelvic organs protrude into the vagina. While transvaginal mesh surgery using non-degradable polymers was a commonly accepted treatment for POP, it has been associated with high rates of adverse events such as mesh erosion, exposure and inflammation due to serious foreign body response and therefore banned from clinical use after regulatory mandates. This study proposes a tissue engineering strategy using uterine endometrium-derived mesenchymal stem/stromal cells (eMSC) delivered with degradable poly L-lactic acid-co-poly ε-caprolactone (PLACL) and gelatin (G) in form of a composite electrospun nanofibrous mesh (P + G nanomesh) and evaluates the immunomodulatory mechanism at the material interfaces. The study highlights the critical acute and chronic inflammatory markers along with remodelling factors that determine the mesh surgery outcome. We hypothesise that such a bioengineered construct enhances mesh integration and mitigates the Foreign Body Response (FBR) at the host interface associated with mesh complications. Our results show that eMSC-based nanomesh significantly increased 7 genes associated with ECM synthesis and cell adhesion including, Itgb1, Itgb2, Vcam1, Cd44, Cdh2, Tgfb1, Tgfbr1, 6 genes related to angiogenesis including Ang1, Ang2, Vegfa, Pdgfa, Serpin1, Cxcl12, and 5 genes associated with collagen remodelling Col1a1, Col3a1, Col6a1, Col6a2, Col4a5 at six weeks post-implantation. Our findings suggest that cell-based tissue-engineered constructs potentially mitigate the FBR response elicited by biomaterial implants. From a clinical perspective, this construct provides an alternative to current inadequacies in surgical outcomes by modulating the immune response, inducing angiogenesis and ECM synthesis during the acute and chronic phases of the FBR.

Differences Between 25-hydroxyvitamin D Levels in Patients with Pelvic Organ Prolapse and Non-Pelvic Organ Prolapse: A Systematic Review

OBJECTIVES

Treatment options for cases of pelvic organ prolapse still lead to the use of a pessary rather than a surgical method. Additional therapy is needed to help treat or prevent pelvic organ prolapse. Vitamin D deficiency has consistently been associated with decreased muscle function, so it is assumed that it will affect the pelvic floor muscles. This paper systematically explores the differences between 25-hydroxyvitamin D levels in patients with pelvic organ prolapse and non-pelvic organ prolapse.

STUDY DESIGN

A systematic review was conducted through the PubMed, Google Scholar, Cochrane Library, and ScienceDirect databases using relevant keywords. Articles published in the last 10 years-from 2012 to 2022-that were written in English, that discuss the status or effect of vitamin D on pelvic organ prolapse, and that focus on 25 OH-vitamin D were included in the review.

RESULTS

In total, 717 articles were filtered but 8 articles met the criteria. A total of 1339 women with prolapse and without prolapse with ages ranging from 20 years to 78 years were included in the study. The studies found did not use the same standard threshold in determining deficiency status. Most studies have found that there are lower levels of vitamin D in women who have had pelvic organ prolapse. A total of 7 of 8 studies confirmed the comparison of vitamin D-25OH levels in women with pelvic organ prolapse and without pelvic organ prolapse at P < 0.05.

CONCLUSIONS

There are differences between 25-hydroxyvitamin D levels in patients with pelvic organ prolapse and non-pelvic organ prolapse.

Extracellular Matrix-Based and Electrospun Scaffolding Systems for Vaginal Reconstruction

Congenital vaginal anomalies and pelvic organ prolapse affect different age groups of women and both have significant negative impacts on patients' psychological well-being and quality of life. While surgical and non-surgical treatments are available for vaginal defects, their efficacy is limited, and they often result in long-term complications. Therefore, alternative treatment options are urgently needed. Fortunately, tissue-engineered scaffolds are promising new treatment modalities that provide an extracellular matrix (ECM)-like environment for vaginal cells to adhere, secrete ECM, and be remodeled by host cells. To this end, ECM-based scaffolds or the constructs that resemble ECM, generated by self-assembly, decellularization, or electrospinning techniques, have gained attention from both clinicians and researchers. These biomimetic scaffolds are highly similar to the native vaginal ECM and have great potential for clinical translation. This review article aims to discuss recent applications, challenges, and future perspectives of these scaffolds in vaginal reconstruction or repair strategies.

Knowledge mapping and visualization analysis of pelvic organ prolapse repair with mesh from 2001 to 2021

Aims: In recent decades, extensive attention has been paid to the application of mesh to repair pelvic floor defects. However, a large body of related literature has not been system summarized. The purpose of this study is to summarize and visualize the literature on pelvic organ prolapse (POP) repair with mesh using bibliometrics. Methods: Medical literature regarding POP repair with mesh were searched and obtained in the Web of Science™ Core (WoSCC) database from 2001 to 2021. Microsoft Excel 2020, CiteSpace and VOSviewer were used to conduct the bibliometric and knowledge-map analysis. Results: In the past 20 years, a total of 2,550 articles and reviews have been published in 35 journals, and the published and cited results show a growing trend. Cosson M and International Urogynecology Journal were the authors and journals with the highest output, respectively. The United States, France and the United Kingdom are among the top three countries/organizations in relevant publications in worldwide. 584 key words in the literature are divided into 8 clusters, which are mainly related to prolapse type, risk factors, surgical methods, imaging, quality of life and bioengineering. Using clinical research and tissue engineering technology to reduce mesh complications is the current hot spot in this field. Conclusion: Reasonable application of mesh and avoiding mesh complications are still the most concerned topics in POP research. Although clinical research, surgical improvement, biological mesh and bioengineering technology have shown promising results, it is still urgent to carry out clinical transformation application research.

Pregnancy outcomes after abdominal sacrocervicopexy

INTRODUCTION AND HYPOTHESIS

Various methods are used in pelvic organ prolapse (POP) surgery. Organ-preserving methods are gaining importance and popularity. Although the success rates of abdominal sacrocervicopexy, which is one of these methods, are known, data on pregnancy outcomes are insufficient. The aim of this study was to investigate pregnancy outcomes after abdominal sacrocervicopexy.

METHODS

This study included 72 patients with a diagnosis of POP who underwent abdominal sacrocervicopexy with monofilament polypropylene mesh in Diyarbakir Gazi Yaşargil Training and Research Hospital between 2008 and 2016. Anterior and posterior colporrhaphy operations were performed. Postoperatively, these patients were followed up for a mean of 29.68 ± 6.55 (20-49) months. Pregnancy and recurrence outcomes of those who became pregnant were recorded and analyzed.

RESULTS

On average, pregnancies occurred 23.2 (18-30) months after the operation. During follow-up, eight patients became pregnant and gave birth without any issues or complications. One had a normal vaginal delivery, and seven gave birth by cesarean section. One of the pregnant women had a twin pregnancy. When 24 patients who underwent bilateral tubal ligation and postmenopausal (n = 2) were excluded, the pregnancy rate was found to be 17.3%. The weeks of the deliveries were 35 weeks (twin pregnancy), 38 weeks (n = 2), 39 weeks (n = 3), and 40 weeks (n = 1), for an average of 38.5 weeks.

CONCLUSIONS

Eight patients who had undergone abdominal sacrocervicopexy had healthy pregnancies and deliveries.

Effect of new-style anterior and posterior vaginal wall repair combined with modified ischial spine fascia fixation on patients with pelvic organ prolapse and their postoperative quality of life

Objective

This study aims to explore the effect of new-style anterior and posterior vaginal wall repair combined with modified ischial spine fascia fixation on patients with pelvic organ prolapse (POP) and their postoperative quality of life.

Methods

A total of 88 patients with POP and elective surgery admitted to Anqing Hospital affiliated to Anhui Medical University from March 2018 to March 2021 were retrospectively analyzed. According to their surgical methods, patients were divided into an observation group [44 cases, all underwent new-style anterior and posterior vaginal wall repair combined with modified ischial spine fascia fixation (new-style APVR-modified ISFF)] and a control group [44 cases, all underwent traditional anterior and posterior vaginal wall repair combined with sacrospinous ligament fixation (traditional APVR- SLF)]. The perioperative indicators were compared between the two groups. The pelvic floor function, pelvic organ prolapse quantification (POP-Q) classification, and quality of life were observed before operation, 3 months after operation, and 6 months after operation. All patients were followed-up.

Results

Compared with the control group, the observation group had more advantages in intraoperative blood loss, operation time, urinary catheter indwelling time, postoperative anal exhaust time, and hospitalization time (P < 0.05). In terms of pelvic floor function, patients of both groups showed significant improvement at 3 months and 6 months after surgery (P < 0.05). In terms of quality of life, the two groups exhibited significant improvement at 6 months after surgery (P < 0.05). PFIQ-7, PFDI-20, and UDI-6P of the observational group were lower than those of the control group, while PISQ-12 was higher than that of the control group but all with no significant difference (P > 0.005). In addition, the total complication rate of the observation group was 2.27% (1/44), which was significantly lower than 22.73% (10/44) of the control group (P < 0.05).

Conclusion

New-style APVR-modified ISFF can effectively treat POP and improve the quality of life of such patients, with less postoperative complications and high safety.

Effects of Pelvic-Floor Muscle Training in Patients with Pelvic Organ Prolapse Approached with Surgery vs. Conservative Treatment: A Systematic Review

The aim of this systematic review was to explore the effectiveness of pelvic-floor muscle training (PFMT) in the treatment of women with pelvic organ prolapse (POP) who had undergone either surgery or only conservative treatment, based on a selection of randomized clinical trials (RCT). The search was carried out in PubMed, Cochrane, Scopus, CINAHL, and PEDro databases between April 2021 and October 2021 using the following MeSH terms or keywords: “pelvic organ prolapse”, “POP”, “pelvic floor muscle training”, “pelvic floor muscle exercise”, “kegel exercise”, and “surgery”. The methodological quality of the studies was assessed using the PEDro scale. Eighteen RCTs were included in this review. The findings showed improvements in symptoms associated with POP, in pelvic-floor function, and in quality of life in women who performed a PFMT protocol. However, PFMT did not produce significant changes in sexual function, and the results of the change in POP stage were inconclusive. When viewing PFMT as a complementary treatment to surgery, no significant improvements were observed in any of the analyzed variables. In conclusion, a PFMT program is an effective way to improve the pelvic, urinary, and intestinal symptoms associated with POP; function of the pelvic floor; and quality of life. PFMT as an adjunct to surgery does not seem to provide a greater benefit than surgical treatment alone. RCTs of higher methodological quality, with a larger sample size and a longer follow-up, are needed to confirm the results.

An updated systematic review and network meta-analysis comparing open, laparoscopic and robotic-assisted sacrocolpopexy for managing pelvic organ prolapse

Abdominal sacrocolpopexy is considered as the gold standard treatment for pelvic organ prolapse. Sacrocolpopexy can be performed using open (OSC), laparoscopic (LSC), and robotic-assisted (RSC) approaches. The aim of this study is to compare the outcomes between these three approaches for managing pelvic organ prolapse by conducting a systematic review and network meta-analysis. A systematic search was performed in different databases from their earliest records to April 2021 with no restriction on languages. Only randomized controlled trials that compared the outcomes between OSC, LSC, and RSC were included in this study. A total of 6 studies with 486 participants were included in this study. Operative time was significantly shorter in OSC than in RSC and LSC. The probability rank showed less estimated blood loss in RSC and lowest overall postoperative complications in LSC. Probability scores also showed best anatomical outcomes for postoperative points C and Bp in RSC and for point Ba in LSC. Despite significantly longer operative time, RSC and LSC may provide better anatomical outcomes, less estimated blood loss, and less overall postoperative complications than OSC. However, this study did not find significant differences between RSC and LSC in efficacy and safety.

Comparing the outcomes and effectiveness of robotic-assisted sacrocolpopexy and laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Abdominal sacrocolpopexy is regarded as the gold standard for management of pelvic organ prolapse (POP). Nowadays, minimally invasive surgeries are preferred, and sacrocolpopexy can be performed using either a laparoscopic or robotic-assisted approach. The aim of the current study was to compare the efficacy and safety of robotic-assisted sacrocolpopexy (RASC) and laparoscopic sacrocolpopexy (LSC) through an updated systematic review and meta-analysis.

METHODS

We performed a systematic literature review of different databases and related references from their inception until July 2020 without language restrictions. All randomized control trials and comparative studies that compared RASC and LSC for the management of POP were included.

RESULTS

A total of 13 studies including 2115 participants were included for the pooled analysis. The pooled results revealed that RASC was associated with a significantly longer operative time (weighted mean difference, 29.53 min; 95% confidence interval [CI], 12.88 to 46.18 min, P = 0.0005), significantly less estimated blood loss (weighted mean difference, -86.52 ml; 95% CI -130.26 to -42.79 ml, P = 0.0001), significantly fewer overall intraoperative complications (odds ratio [OR] 0.6; 95% CI 0.40 to 0.91; P = 0.01) and significantly lower conversion rate (OR 0.39; 95% CI 0.19 to 0.82; P = 0.01) compared with LSC. There were no significant differences between the length of hospital stays, overall postoperative complications, postoperative stress incontinence, mesh erosion and effectiveness between the two groups.

CONCLUSION

The current study showed comparable efficacy between RASC and LSC. Though RASC was associated with less blood loss and a lower conversion rate, the differences were not clinically significant. The choice of surgical procedure with either RASC or LSC is according to surgeon discretion and patient preferences.
