Complication and Reoperation Rates After Apical Vaginal Prolapse Surgical Repair: A Systematic Review

Prospective study of transobturator mesh kit (Prolift™) in pelvic reconstructive surgery with vaginal hysterectomy after 3 years' follow-up

INTRODUCTION AND HYPOTHESIS

This study is to analyze prospectively the anatomical and functional outcomes of transvaginal pelvic reconstructive surgery using the Prolift™ system for pelvic organ prolapse (POP) with hysterectomy.

METHODS

A prospective, observational, noncomparative study was conducted in 80 patients with prolapse ≥ 2. Postoperative pelvic organ prolapse quantification stage was the main outcome measure. Anatomical cure was defined as vaginal vault stage 0 and improvement as stage 1. Secondary outcomes include pelvic floor distress inventory-20, incontinence impact questionnaire short form-7, and pelvic floor impact questionnaire short form-7.

RESULTS

A total of 80 patients were recruited. The cure and improvement rates were 96.3 % (77/80) and 3.7 % (3/80) respectively at 1 year. At the follow-up of 3-years, the cure rates were 93.3 % (70/75). Among the five patients, three had stage 2 anterior wall prolapse, two had stage 2 posterior wall prolapse. Only one patient with intraoperative adverse event (rectal perforation) was encountered. Postoperative complications included prolonged catheterization in three patients (3.7 %), postoperative stress urinary incontinence in five patients (6.25 %) and asymptomatic mesh extrusions in five patients (6.25 %). All of them occurred within 1 year follow-up. Significant improvements in quality of life were detected at 1 and 3 years compared with baseline.

CONCLUSION

The total Prolift™ system surgery represents a safe, simple and useful treatment for severe POP with satisfactory objective clinical outcomes.

Where to for pelvic organ prolapse treatment after the FDA pronouncements? A systematic review of the recent literature

INTRODUCTION

With the publication of the updated US Food and Drug Administration (FDA) communication in 2011 on the use of transvaginal placement of mesh for pelvic organ prolapse (POP) it is appropriate to now review recent studies of good quality on POP to assess the safety and effectiveness of treatment options and determine their place in management.

METHODS

A systematic search for studies on the conservative and surgical management of POP published in the English literature between January 2002 and October 2012 was performed. Studies included were review articles, randomized controlled trials, prospective and relevant retrospective studies as well as conference abstracts. Selected articles were appraised by the authors regarding clinical relevance.

RESULTS

Prospective comparative studies show that vaginal pessaries constitute an effective and safe treatment for POP and should be offered as first treatment of choice in women with symptomatic POP. However, a pessary will have to be used for the patient's lifetime. Abdominal sacral colpopexy is effective in treating apical prolapse with an acceptable benefit-risk ratio. This procedure should be balanced against the low but non-negligible risk of serious complications. The results of native tissue vaginal POP repair are better than previously thought with high patient satisfaction and acceptable reoperation rates. The insertion of mesh at the time of anterior vaginal wall repair reduces the awareness of prolapse as well as the risk of recurrent anterior prolapse. There is no difference in anatomic and subjective outcome when native tissue vaginal repairs are compared with multicompartment vaginal mesh. Mesh exposure is still a significant problem requiring surgical excision in approximately ≥ 10 % of cases. The ideal mesh has not yet been found necessitating more basic research into mesh properties and host response. Several studies indicate that greater surgical experience is correlated with fewer mesh complications. In women with uterovaginal prolapse uterine preservation is a feasible option which women should be offered. Randomized studies with long-term follow-up are advisable to establish the place of uterine preservation in POP surgery.

CONCLUSION

Over the last decade treatment of POP has been dominated by the use of mesh. Conservative treatment is the first option in women with POP. Surgical repair with or without mesh generally results in good short-term objective and functional outcomes. However, basic research into mesh properties with host response and comparative studies with long-term follow-up are urgently needed.

Prospective study of an ultra-lightweight polypropylene Y mesh for robotic sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

To prospectively evaluate the use of a particular polypropylene Y mesh for robotic sacrocolpopexy.

METHODS

This was a prospective study of 120 patients who underwent robotic sacrocolpopexy. We compared preoperative and 12-month postoperative objective and subjective assessments via the Pelvic Organ Prolapse Quantification (POP-Q), the Pelvic Floor Distress Inventory, Short Form 20 (PFDI-20); the Pelvic Floor Impact Questionnaire, Short Form 7 (PFIQ-7); and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire 12 (PISQ-12). Objective "anatomical success" was defined as POP-Q stage 0 or 1 at all postoperative intervals. We further defined "clinical cure" by simultaneously considering POP-Q points and subjective measures. To be considered a "clinical cure," a given patient had to have all POP-Q points ≤0, apical POP-Q point C ≤5, no reported pelvic organ prolapse symptoms on the PFDI-20, and no reoperation for prolapse at all postoperative intervals.

RESULTS

Of the 120 patients, 118 patients completed the 1-year follow-up. The objective "anatomical success" rate was 89 % and the "clinical cure" rate was 94 %. The PFDI-20 mean score improved from 100.4 at baseline to 21.0 at 12 months (p < 0.0001); PFIQ-7 scores improved from 61.6 to 8.0 (p < 0.0001); and PISQ-12 scores improved from 35.7 to 38.6 (p < 0.0009). No mesh erosions or mesh-related complications occurred.

CONCLUSION

The use of this ultra-lightweight Y mesh for sacrocolpopexy, eliminated the mesh-related complications in the first postoperative year, and provided significant improvement in subjective and objective outcomes.

Deterioration in biomechanical properties of the vagina following implantation of a high-stiffness prolapse mesh

OBJECTIVE

To define the impact of prolapse mesh on the biomechanical properties of the vagina by comparing the prototype Gynemesh PS (Ethicon) to two new-generation lower stiffness meshes, SmartMesh (Coloplast) and UltraPro (Ethicon).

DESIGN

A study employing a nonhuman primate model.

SETTING

University of Pittsburgh, PA, USA.

POPULATION

Forty-five parous rhesus macaques.

METHODS

Meshes were implanted via sacrocolpopexy after hysterectomy and compared with sham. Because its stiffness is highly directional, UltraPro was implanted in two directions: UltraPro Perpendicular (less stiff) and UltraPro Parallel (more stiff), with the indicated direction referring to the position of the blue orientation lines relative to the longitudinal axis of the vagina. The mesh-vaginal complex (MVC) was excised in toto after 3 months.

MAIN OUTCOME MEASURES

Active mechanical properties were quantified as the contractile force generated in the presence of 120 mmol/l KCl. Passive mechanical properties (a tissue's ability to resist an applied force) were measured using a multiaxial protocol.

RESULTS

Vaginal contractility decreased by 80% following implantation with the Gynemesh PS (P = 0.001), 48% after SmartMesh (P = 0.001), 68% after UltraPro Parallel (P = 0.001) and was highly variable after UltraPro Perpendicular (P = 0.16). The tissue contribution to the passive mechanical behaviour of the MVC was drastically reduced for Gynemesh PS (P = 0.003), but not for SmartMesh (P = 0.9) or UltraPro independent of the direction of implantation (P = 0.68 and P = 0.66, respectively).

CONCLUSIONS

Deterioration of the mechanical properties of the vagina was highest following implantation with the stiffest mesh, Gynemesh PS. Such a decrease associated with implantation of a device of increased stiffness is consistent with findings from other systems employing prostheses for support.

The pelvic floor complication scale: a new instrument for reconstructive pelvic surgery

OBJECTIVE

The purpose of this study was to develop and test a unique, new pelvic floor surgery complication scale and compare it with an existing validated measure.

STUDY DESIGN

Surgeons from 2 clinical trials networks rated complications based on perceived patient bother, severity, and duration of disability to develop a pelvic floor complication scale (PFCS). PFCS scores were calculated for subjects in 2 multicenter pelvic floor surgical trials. The PFCS and modified Clavien-Dindo scores were evaluated for associations with length of hospitalization, satisfaction, and quality-of-life measures (health utilities index, short form-36, urogenital distress inventory, and incontinence impact questionnaire).

RESULTS

We calculated PFCS scores for 977 subjects. Higher PFCS and Clavien-Dindo scores similarly were associated with longer length of hospitalization (P < .01), lower satisfaction (P < .01), lower Health Utilities Index scores (P = .02), lower short form-36 scores (P = .02), higher urogenital distress Inventory scores (P < .01), and incontinence impact questionnaire scores (P < .01) at 3 months. No associations were present at 1 year.

CONCLUSION

The PFCS compares favorably to the validated modified Clavien-Dindo instrument.

Ureteral injury during vaginal mesh excision: role of prevention and treatment options

Vaginal mesh kits are increasingly used in vaginal prolapse repair. Mesh erosion, infection, and pain may necessitate removal, which can lead to urinary tract injury. We describe 2 cases of ureteral injury at the time of mesh excision. Surgeons must recognize the possibility of ureteral injury and treatment modalities available.

Vaginal mesh - the controversy

Pelvic organ prolapse is a condition that can cause significant symptoms that affect a woman's quality of life. It is the result of defects in the supporting structures of the vagina and, depending on the location and size, can alter the functions of the organs contained within the female pelvis. Approximately 11% of women will undergo surgical intervention for their prolapse or for incontinence in their lifetime. Unfortunately, one third of these will require reoperation for failed procedures. Pelvic floor surgeons have sought to improve these outcomes. Based largely on the success of midurethral slings (MUS), transvaginal mesh has been implanted, and commercial kits developed with the intent of improving these outcomes. In 2008, the Food and Drug Administration (FDA) issued a Public Health Notification in response to possible increased adverse events associated with the use of mesh compared to traditional repairs. The 2011 update required that further study be conducted for the use of transvaginal mesh. In this article, we wish to discuss the background of mesh use and the evolution of the public health warnings, and focus on future prospects.

Induced Regenerative Elastic Matrix Repair in LOXL1 Knockout Mouse Cell Cultures: Towards Potential therapy for Pelvic Organ Prolapse

Impaired elastic matrix remodeling occurs in reproductive tissues after vaginal delivery. This has been linked to development of pelvic organ prolapse (POP) for which there currently is no pharmacologic therapy. Hyaluronan oligomers and transforming growth factor beta 1 (termed elastogenic factors, EFs) have been shown to significantly enhance tropoelastin synthesis, elastic fiber assembly, and crosslinking by adult vascular smooth muscle cells (SMCs). The goal of this study was to ascertain if these factors similarly improve the quantity and quality of elastic matrix deposition by vaginal SMCs (VSMCs) isolated from lysyl oxidase like-1 knock out (LOXL1 KO) mouse model of POP. Cells isolated from whole vagina of a LOXL1 KO mouse (multiparous, stage 3 prolapse) were cultured and identified as SMCs by their expression of various SMC markers. Passage 2 vaginal SMCs (VSMCs; 3×10⁴/10 cm²) were cultured for 21 days with EFs. Cell layers and spent medium aliquots were assessed for elastin content and quality. EF-treated VSMCs proliferated at a similar rate to untreated controls but synthesized more total elastin primarily in the form of soluble matrix elastin. Elastin mRNA was also increased compared to controls. The elastic matrix was significantly denser in EF-treated cultures, which was composed of more mature, non-interrupted elastic fibers that were absent in controls. The results are promising towards development of a therapy to enhance regenerative elastic matrix repair in post-partum female pelvic floor tissues.

Prevention of complications related to the use of prosthetic meshes in prolapse surgery: guidelines for clinical practice

The objective of the study was to provide guidelines for clinical practice from the French College of Obstetrics and Gynecology (CNGOF), based on the best evidence available, concerning adverse events related to surgical procedures involving the use of prosthetic meshes. French and English-language articles from Medline, PubMed, and the Cochrane Database were searched, using key words (mesh; pelvic organ prolapse; cystocele; rectocele; uterine prolapse; complications; adverse event; sacral colpopexy; extrusion; infection). As with any surgery, recommendations include perioperative smoking cessation (Expert opinion) and compliance with the prevention of nosocomial infections (regulatory recommendation). There is no evidence to recommend routine local or systemic estrogen therapy before or after prolapse surgery using mesh, regardless of the surgical approach (Grade C). Antibiotic prophylaxis is recommended, regardless of the approach (Expert opinion). It is recommended to check for pre-operative urinary tract infection and treat it (Expert opinion). The first procedure should be undertaken under the guidance of a surgeon experienced in the relevant technique (Grade C). It is recommended not to place a non-absorbable synthetic mesh into the rectovaginal septum when a rectal injury occurs (Expert opinion). Placement of a non-absorbable synthetic mesh into the vesicovaginal septum may be considered after suturing of a bladder injury if the suture is considered to be satisfactory (Expert opinion). If a synthetic mesh is placed by vaginal route, it is recommended to use a macroporous polypropylene monofilament mesh (Grade B). It is recommended not to use polyester mesh for vaginal surgery (Grade B). It is permissible to perform hysterectomy associated with the placement of a non-absorbable synthetic mesh placed by the vaginal route but this is not routinely recommended (Expert opinion). It is recommended to minimize the extent of the colpectomy (Expert opinion). The laparoscopic approach is recommended for sacral colpopexy (Expert opinion). It is recommended not to place and suture meshes by the vaginal route when a sacral colpopexy is performed (Grade B). It is recommended not to use silicone-coated polyester, porcine dermis, fascia lata, and polytetrafluoroethylene meshes (Grade B). It is recommended to use polyester (without silicone coating) or polypropylene meshes (Grade C). Suture of the meshes to the promontory can be performed using thread/needle or tacks (Grade C). Peritonization is recommended to cover the meshes (Grade C). If hysterectomy is required, it is recommended to perform a subtotal hysterectomy (Expert opinion). Implementation of this guideline should decrease the prevalence of complications related to surgical procedures involving the use of prosthetic meshes.

An International Urogynecological Association (IUGA)/International Continence Society (ICS) joint report on the terminology for reporting outcomes of surgical procedures for pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Standardized terminology has yet to be developed for reporting the outcomes for surgery for pelvic organ prolapse (POP).

METHODS

This report combines the input of the Terminology and Standardization Committees of the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a joint Working Group on this topic, as well as expert external referees. The aim was to present a standardized terminology for the definitions of surgery and propose a structure for reporting the outcomes of surgical procedures for POP. An extensive drafting and review process was undertaken, as well as open review on both IUGA and ICS websites.

RESULTS

A terminology report was developed outlining the recommended structure for reporting outcomes of surgical trials involving POP. This document does not define success and failure. The report includes patient-reported, subjective and objective outcomes to enable researchers to report on their results and compare them with other studies.

CONCLUSIONS

A consensus-based method for standardizing terminology for reporting outcome measures of POP surgery was developed to aid clinicians working in this area of research.

Tissue engineering as a potential alternative or adjunct to surgical reconstruction in treating pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

Cell-based tissue engineering strategies could potentially provide attractive alternatives to surgical reconstruction of native tissue or the use of surgical implants in treating pelvic organ prolapse (POP).

METHODS

Based on a search in PubMed, this review focuses on candidate cell types, scaffolds, and trophic factors used in studies examining cell-based tissue engineering strategies to treat POP, stress urinary incontinence (SUI), and the closely related field of hernias.

RESULTS

In contrast to the field of SUI, the use of cell-based tissue engineering strategies to treat POP are very sparsely explored, and only preclinical studies exist.

CONCLUSION

The available evidence suggests that the use of autologous muscle-derived cells, fibroblasts, or mesenchymal stem cells seeded on biocompatible, degradable, and potentially growth-promoting scaffolds could be an alternative to surgical reconstruction of native tissue or the use of conventional implants in treating POP. However, the vagina is a complex organ with great demands of functionality, and the perfect match of scaffold, cell, and trophic factor has yet to be found and tested in preclinical studies. Important issues such as safety and economy must also be addressed before this approach is ready for clinical studies.

Surgical options for apical prolapse repair

Pelvic organ prolapse is a common medical condition that affects the quality of life of many women. Approximately 50% of parous women have pelvic organ prolapse and the lifetime risk for surgical intervention is 6.7% at the age of 80 years. In the USA, the number of women at risk for symptomatic prolapse is increasing, which is consistent with the recent increase in the overall number of prolapse and incontinence procedures being performed. Although prolapse is usually multicompartmental and isolated defects are rare, the apical compartment deserves special attention because apical support is integral to a durable prolapse repair. Since many women may initially present to their primary care physicians, all members of the medical community should have a basic understanding of the diagnosis and treatment for apical prolapse.

Multilayer, degradable coating as a carrier for the sustained release of antibiotics: preparation and antimicrobial efficacy in vitro

One of the most critical post-surgical complications is mesh-related infection. This paper describes how a commercially available polypropylene (PP) mesh was modified to minimize the risk of post-implantation infection. A dual drug-release coating was created around mesh filaments using an airbrush spray system. This coating was composed of three layers containing ofloxacin and rifampicin dispersed in a degradable polymer reservoir made up of [poly(ε-caprolactone) (PCL) and poly(DL-lactic acid) (PLA)]. Drug release kinetics were managed by varying the structure of the degradable polymer and the multilayer coating. In vitro, this new drug delivery polymer system was seen to be more rapidly invaded by fibroblasts than was the initial PP mesh. Active mesh showed excellent antibacterial properties with regard to microorganism adhesion, biofilm formation and the periprosthetic inhibition of bacterial growth. Sustained release of the two antibiotics from the coated mesh prevented mesh contamination for at least 72 h. This triple-layer coating technology is potentially of great interest for it can be easily extrapolated to other medical devices and drug combinations for the prevention or treatment of other diseases.

Computer modeling informs study design: vaginal estrogen to prevent mesh erosion after different routes of prolapse surgery

INTRODUCTION AND HYPOTHESIS

Many clinicians use perioperative vaginal estrogen therapy (estradiol, E(2)) to diminish the risk of mesh erosion after prolapse surgery, though supporting evidence is limited. We assessed the feasibility of a factorial randomized trial comparing mesh erosion rates after vaginal mesh prolapse surgery (VM) versus minimally invasive sacral colpopexy (MISC), with or without adjunct vaginal estrogen therapy.

METHODS

A Markov state transition model simulated the probability of 2-year outcomes of visceral injury, mesh erosion, and reoperation after four possible prolapse therapies: VM or MISC, each with or without estrogen therapy (E(2)). We used pooled estimates from a systematic review to generate probability distributions for the following outcomes after each procedure: visceral injury, postoperative mesh erosion, and reoperation for either recurrent prolapse or mesh erosion. Assuming different assumptions for E(2) efficacies (50 and 75 % reduction in erosion rates), Monte Carlo simulations estimated outcomes rates, which were then used to generate sample size estimates for a four-arm factorial trial.

RESULTS

While E(2) reduced the risk of mesh erosion for both VM and MISC, absolute reduction was small. Assuming 75 % efficacy, E(2) decreased the risk of mesh erosion for VM from 7.8 to 2.0 % and for MISC from 2.0 to 0.5 %. Total sample sizes ranged from 448 to 1,620, depending on power and E(2) efficacy.

CONCLUSIONS

The required sample size for a trial to determine which therapy results in the lowest erosion rates would be prohibitively large. Because this remains an important clinical issue, further study design strategies could include composite outcomes, cost-effectiveness, or value of information analysis.

Vaginal placement of synthetic mesh for pelvic organ prolapse

Since 2004, use of synthetic mesh has increased in vaginal surgery for the treatment of pelvic organ prolapse. However, concerns exist about the safety and efficacy of transvaginally placed mesh. Based on the currently available limited data, although many patients undergoing mesh-augmented vaginal repairs heal well without problems, there seems to be a small but significant group of patients who experience permanent and life-altering sequelae, including pain and dyspareunia, from the use of vaginal mesh. The American College of Obstetricians and Gynecologists and the American Urogynecologic Society provide background information on the use of vaginally placed mesh for the treatment of pelvic organ prolapse and offer recommendations for practice.

Interrater reliability of the International Continence Society and International Urogynecological Association (ICS/IUGA) classification system for mesh-related complications

OBJECTIVE

We sought to assess interrater reliability of the International Continence Society (ICS)/International Urogynecological Association (IUGA) classification system of vaginal mesh-related complications and compare this with several other available complication classification systems.

STUDY DESIGN

This was a retrospective analysis of mesh-related complications in patients presenting after pelvic organ prolapse or incontinence surgery. The complications were classified by 2 independent reviewers using the ICS/IUGA classification system as well as 3 other available classification systems. Interrater reliability was assessed using percent agreement and the weighted κ statistic.

RESULTS

The ICS/IUGA mesh complication classification system was found to have poor interrater reliability (κ = 0.15-0.78). The other systems yielded a κ that ranged from 0.18-0.60, but were too general or could only be applied to 68% of the complications.

CONCLUSION

The complexity of the ICS/IUGA mesh complication system, the large number of categories, and lack of clarity likely contribute to its poor interrater reliability.

A novel transvaginal approach to correct recurrent apical prolapse after failed sacral colpopexy: case series

INTRODUCTION AND HYPOTHESIS

The objective of the study was to describe the transvaginal approach utilizing the existing sacral colpopexy (SC) graft for recurrent apical prolapse following failed SC.

METHODS

Twenty-two patients with recurrent vaginal vault prolapse following a prior SC were treated between January 2000 and December 2009. Twelve patients had a standard uterosacral ligament cuff suspension (USLS) performed. In ten patients, the vaginal cuff was suspended to the left uterosacral ligament and reattached to the graft material from the prior SC. One of these ten subsequently failed and a standard USLS was performed. Patient characteristics, preoperative pelvic floor assessment, operative information, and postoperative follow-up were collected. Cases in which the graft material was used were compared with those undergoing standard USLS.

RESULTS

Demographic characteristics and preoperative Baden-Walker scores were similar. Of 23 cases, 21 (91 %) were a consequence of graft separation from the vagina and not the sacrum. Two of nine patients with follow-up where the SC graft was utilized transvaginally had recurrent prolapse. One required reoperation. Of 13 patients in the group that underwent traditional USLS, 2 had asymptomatic recurrent anterior prolapse; neither required additional surgery.

CONCLUSIONS

A transvaginal surgical approach for recurrent vaginal prolapse after a history of failed abdominal SC should be considered. If feasible, the SC graft material can be used when performing USLS instead of the right uterosacral ligament for these patients with a prior history of abdominal SC.

Beyond the complications: medium-term anatomical, sexual and functional outcomes following removal of trocar-guided transvaginal mesh. A retrospective cohort study

INTRODUCTION AND HYPOTHESIS

The aims of this study were to assess the anatomical, sexual and functional outcomes of women undergoing surgical intervention for complications of the trocar-guided transvaginal mesh (TVM) procedure.

METHODS

This was a retrospective analysis of a clinical database of women who had developed a complication following a TVM procedure. This included dyspareunia, mesh erosion, urinary symptoms, mesh contraction and prolapse recurrence. Pre- and post-operatively, we assessed the women for prolapse, stress incontinence, urgency, defecatory difficulty, digitation, pain, dyspareunia and apareunia. We also recorded the Pelvic Organ Prolapse Quantification (POP-Q) score. The TVM was removed and a Biodesign graft was used in the majority of cases to prevent further prolapse. Follow-up was at 6 weeks, 6 months, 1 and 2 years.

RESULTS

In our cohort of 21 women, 18 required surgery for pain and/or dyspareunia; 20 women had reached the 6-week follow-up at the time of analysis. At 6 weeks, two women still had pain and required a second intervention. Fifteen women had reached a 6-month follow-up and only one woman had persistent pain requiring repeat surgery. Of the 15 women, 7 were sexually active and in 6 cases the dyspareunia had resolved completely with 1 woman retaining an element of pain at intercourse. Six women had been seen at 12 months and all four of the sexually active women had no dyspareunia. There were no symptoms relating to prolapse in any of the women at 6 weeks, 6, 12 or 24 months.

CONCLUSIONS

We report satisfactory outcomes following removal of a complicated TVM kit.

Mesh complications in female pelvic floor reconstructive surgery and their management: A systematic review

We reviewed the incidence, predisposing factors, presentation and management of complications related to the use of synthetic mesh in the management of stress urinary incontinence and pelvic organ prolapse repair. Immediate complications, such as bleeding, hematoma, injury to adjacent organs during placement of mesh and complication of voiding dysfunction are not discussed in this review, since they are primarily related to technique. A PubMed search of related articles published in English was done from April 2008 to March 2011. Key words used were urinary incontinence, mesh, complications, midurethral sling, anterior prolapse, anterior vaginal repair, pelvic organ prolapse, transvaginal mesh, vault prolapse, midurethral slings, female stress urinary incontinence, mesh erosion, vaginal mesh complications, and posterior vaginal wall prolapse. Since there were very few articles dealing with the management of mesh-related complications in the period covered in the search we extended the search from January 2005 onwards. Articles were selected to fit the scope of the topic. In addition, landmark publications and Manufacturer and User Facility Device Experience (MAUDE) data (FDA website) were included on the present topic. A total of 170 articles were identified. The use of synthetic mesh in sub-urethral sling procedures is now considered the standard for the surgical management of stress urinary incontinence. Synthetic mesh is being increasingly used in the management of pelvic organ prolapse. While the incidence of extrusion and erosion with mid-urethral sling is low, the extrusion rate in prolapse repair is somewhat higher and the use in posterior compartment remains controversial. When used through the abdominal approach the extrusion and erosion rates are lower. The management of mesh complication is an individualized approach. The choice of the technique should be based on the type of mesh complication, location of the extrusion and/or erosion, its magnitude, severity and potential recurrence of pelvic floor defect.

Abdominal extraperitoneal excision of a foreign body in the pararectal space

Permanent suture material and synthetic grafts can be used as part of pelvic organ prolapse surgery. These materials are often attached to the sacrospinous ligament or passed in retroperitoneal spaces. There is a risk for erosion and granulation tissue formation with any of these materials. Typically, this is managed through a transvaginal incision.We present a case of a postmenopausal woman with persistent granulation tissue and a sinus tract from a braided polyester (Ethibond) suture placed in the right sacrospinous ligament fixation. After failing several attempts at treating this granulation tissue through a vaginal incision, we managed this via an abdominal retroperitoneal approach.

Subjective and objective outcomes 1 year after robotic-assisted laparoscopic sacrocolpopexy

We aimed to assess the subjective and objective outcomes 1 year after robotic sacrocolpopexy using a type I polypropylene mesh. This was a case series of 64 patients who underwent a robotic-assisted laparoscopic sacrocolpopexy using a type I monofilament polypropylene mesh coated with hydrophilic porcine collagen. Objective and subjective outcomes were assessed using the pelvic organ prolapse quantification (POP-Q), the short forms of the Pelvic Floor Impact Questionnaire (PFIQ 7) and the Pelvic Floor Distress Inventory (PFDI-20). Outcome measures were collected pre-operatively and 1 year post-operatively on all but one patient, who was lost to follow-up. Paired comparisons between pre- and post-operative outcomes were performed using the Wilcoxon signed rank test. At 1 year, POP-Q stage II or greater and loss of follow-up were considered to be surgical failure. The "surgical cure" rate was 89%. We observed three distal anterior failures, two distal posterior failures and one apical failure, and one patient was lost to follow-up. We found significant differences between pre- and post-operative POP-Q measurements (p < 0.001) and PFDI-20/PFIQ-7 total scores (p < 0.001). Robotic sacrocolpopexy using this polypropylene mesh resulted in significant improvements in subjective and objective outcome measures at 1 year.

Surgical intervention after transvaginal Prolift mesh repair: retrospective single-center study including 524 patients with 3 years' median follow-up

OBJECTIVE

The aim of this study was to explore the nature and rate of surgical intervention after transvaginal Prolift mesh repair for pelvic organ prolapse.

STUDY DESIGN

This was a retrospective study of all patients who underwent Prolift mesh repair between January 2005 and January 2009. Patient data were obtained from medical records, and patients were telephoned to check if they had surgery in other hospitals.

RESULTS

A total of 600 consecutive patients were identified. Of these, 524 patients (87.3%) were included in the study, with a median follow-up duration of 38 months (range, 15-63). Global reoperation rate was 11.6%. Indications of intervention were surgery for urinary incontinence (6.9%), mesh-related complications (3.6%), or prolapse recurrence (3%).

CONCLUSION

The global reoperation rate after transvaginal Prolift mesh repair was 11.6%, with urinary incontinence surgery being the most common indication. Rates of mesh complications and prolapse recurrence are relatively low in an experienced team.

One-year objective and functional outcomes of a randomized clinical trial of vaginal mesh for prolapse

OBJECTIVE

The purpose of this study was to show 12-month outcomes of a randomized trial that compared vaginal prolapse repair with and without mesh.

STUDY DESIGN

Women with stage ≥2 prolapse were assigned randomly to vaginal repair with or without mesh. The primary outcome was prolapse stage ≤1 at 12 months. Secondary outcomes included quality of life and complications.

RESULTS

All 65 evaluable participants were followed for 12 months after trial stoppage for mesh exposures. Thirty-two women had mesh repair; 33 women had traditional repair. At 12 months, both groups had improvement of pelvic organ prolapse-quantification test points to similar recurrence rates. The quality of life improved and did not differ between groups: 96.2% mesh vs 90.9% no-mesh subjects reported a cure of bulge symptoms; 15.6% had mesh exposures, and reoperation rates were higher with mesh.

CONCLUSION

Objective and subjective improvement is seen after vaginal prolapse repair with or without mesh. However, mesh resulted in a higher reoperation rate and did not improve 1-year cure.

Minimally invasive urogynecology

Laparoscopic and other forms of minimally invasive pelvic floor defect repair represent alternative approaches to performing established procedures; laparoscopy can offer benefits to the surgeon (improved visualization, access for multiple procedures) and patient (decreased pain, scar formation, recuperation, and improved cosmesis). Many practitioners prefer the term “minimal access surgery” to the more prevalent “minimally invasive surgery,” as, ideally, only the route of access, not the procedure itself, is changed. Similarly, dialogue and debate about the merits and concerns of trocar-based mesh prolapse repair kits continue. While gynecology will benefit from further investigations of outcomes of minimally invasive pelvic reconstruction,there is evidence already that these techniques are feasible and offer options and advantages in the treatment of patients with pelvic floor disorders.

Surgical management of mesh-related complications after prior pelvic floor reconstructive surgery with mesh

INTRODUCTION AND HYPOTHESIS

The objective of this study is to evaluate the complications and anatomical and functional outcomes of the surgical treatment of mesh-related complications.

METHODS

A retrospective cohort study of patients who underwent complete or partial mesh excision to treat complications after prior mesh-augmented pelvic floor reconstructive surgery was conducted.

RESULTS

Seventy-three patients underwent 30 complete and 51 partial mesh excisions. Intraoperative complications occurred in 4 cases, postoperative complications in 13. Symptom relief was achieved in 92% of patients. Recurrence of pelvic organ prolapse (POP) occurred in 29% of complete and 5% of partial excisions of mesh used in POP surgery. De novo stress urinary incontinence (SUI) occurred in 36% of patients who underwent excision of a suburethral sling.

CONCLUSIONS

Mesh excision relieves mesh-related complications effectively, although with a substantial risk of serious complications and recurrence of POP or SUI. More complex excisions should be performed in skilled centers.

Synthetic vaginal mesh for pelvic organ prolapse

PURPOSE OF REVIEW

The purpose of this review is to summarize recently published comparative trials on synthetic vaginal mesh versus traditional native tissue repairs for pelvic organ prolapse.

RECENT FINDINGS

Although studies suggest benefit from the use of synthetic vaginal mesh for anterior compartment prolapse, data are limited on the use of mesh for posterior and apical prolapse when compared with native tissue repair. The benefits of a more durable repair must be weighed against risks such as the development of de-novo stress incontinence, visceral injury, dyspareunia, pelvic pain and mesh contraction, exposure and extrusion requiring reoperation. Furthermore, the success rates of native tissue repairs are higher than previously considered using updated validated composite outcomes that incorporate both subjective relief of bulge and objective cure defined as prolapse above the hymenal ring.

SUMMARY

Surgeons placing synthetic mesh for pelvic organ prolapse should counsel patients regarding the potential benefits, risks, and alternatives including native tissue repairs. Level 1 evidence suggests anterior synthetic mesh may be superior to anterior repair. Expert opinion suggests potential benefit of vaginal mesh for recurrences, hysteropexy, and advanced prolapse in patients with medical co-morbidities precluding invasive open and endoscopic sacrocolpopexies; however, comparative clinical trials with long-term data are needed.

The IUGA/ICS classification of complications of prosthesis and graft insertion: a comparative experience in incontinence and prolapse surgery

INTRODUCTION AND HYPOTHESIS

This is a presentation of case series after the use of alloplasic material in urogynaecology.

METHODS

From 2004 to 2010, a total 179 patients with complications have been referred directly after the use of alloplastic material in incontinence and prolapse surgery. Of this total, 125 patients had a previous vaginal sling plasty because of urinary stress incontinence, while 54 patients underwent a prolapse surgery with mesh use. Symptoms and findings are expressed by the recently introduced International Urogynecological Association/International Continence Society (IUGA/ICS) terminology.

RESULTS

The most frequent findings after vaginal sling plasty were bladder outlet obstruction, pain and tape exposure. The most frequent findings after prolapse surgery were pain and mesh erosion. The IUGA/ICS classification does not give the possibility to express functional disorders. Most revisions were done more than 2 months after surgery. After incontinence surgery, mostly the vaginal area of suture line was affected; after prolapse surgery, the vagina and the trocar passage were affected.

CONCLUSIONS

Mesh complication and affected site after prolapse surgery do differ from those after incontinence surgery. The IUGA/ICS classification of mesh complication facilitates the comparison of mesh complication.

Reanalysis of a randomized trial of 3 techniques of anterior colporrhaphy using clinically relevant definitions of success

OBJECTIVE

The purpose of this study was to reanalyze the results of a previously published trial that compared 3 methods of anterior colporrhaphy according to the clinically relevant definitions of success.

STUDY DESIGN

A secondary analysis of a trial of 114 subjects who underwent surgery for anterior pelvic organ prolapse who were assigned randomly to standard anterior colporrhaphy, ultralateral colporrhaphy, or anterior colporrhaphy plus polyglactin 910 mesh from 1996-1999. For the current analysis, success was defined as (1) no prolapse beyond the hymen, (2) the absence of prolapse symptoms (visual analog scale ≤ 2), and (3) the absence of retreatment.

RESULTS

Eighty-eight percent of the women met our definition of success at 1 year. One subject (1%) underwent surgery for recurrence 29 months after surgery. No differences among the 3 groups were noted for any outcomes.

CONCLUSION

Reanalysis of a trial of 3 methods of anterior colporrhaphy revealed considerably better success with the use of clinically relevant outcome criteria compared with strict anatomic criteria.

Simultaneous correction of anterior and apical vaginal prolapse with the modified placement of the transobturator-guided mesh (Anterior Prolift™) set

AIM

Modified placement of the Anterior Prolift™ (MODAP) in patients with prolapse of the anterior and middle vaginal compartment is described. It was performed in order to achieve simultaneous tension-free correction of the anterior and middle vaginal compartment without excessive use of the mesh.

MATERIAL AND METHODS

MODAP was performed in 32 patients. The anterior part of the mesh was placed transobturatorily. Surplus of the central part of the mesh was longitudinally divided and fixed around the cervix. Posterior mesh arms were passed through the sacrospinous ligament. All patients were analyzed regarding anatomy and symptoms 1 year after surgery.

RESULTS

Cure of pelvic organ prolapse was achieved in 28 of 32 (87.5%) patients. The position of Ba and C points was significantly corrected (p = 0.00). Deterioration of the posterior compartment occurred in 1 case. Symptoms of pelvic organ prolapse were significantly corrected (p = 0.05 up to p = 0.00) except for rectal emptying.

CONCLUSION

MODAP makes an improvement of both anatomy support and symptoms in cases with mixed insufficiency of the anterior vaginal wall and apical vaginal support.

Transvaginal mesh for prolapse repair: what is all the controversy about?

The use of synthetic mesh for the management of pelvic organ prolapse has been embroiled in a contentious debate over the past decade, with only more partisanship among physicians strictly against its use versus those pelvic surgeons who believe it to be a useful tool in their armamentarium. At the heart of the controversy lies the concern, by its detractors, for complications related to mesh use outweighing the as yet not rigorously tested benefit of augmenting repairs with mesh. This article discusses, in detail, the current literature supporting the use of mesh in the management of pelvic organ prolapse repair. The rising concern for complications, both simple and complex, will be addressed. This review aims to narrow the divide between physicians and to address their discordant beliefs by objectively reporting the most up-to-date data on biologic and synthetic mesh use in pelvic organ prolapse repair.

Is robotic sacrocolpopexy a marketing gimmick or a technological advancement?

PURPOSE OF REVIEW

Robot-assisted laparoscopic sacrocolpopexy (RALS) is a new surgical technique for the treatment of symptomatic vaginal vault prolapse that is rapidly gaining popularity among both urologists and gynecologists. This article will summarize the available published data to assess the potential advantages and disadvantages of this new procedure and its current role in female pelvic floor reconstruction.

RECENT FINDINGS

The literature on RALS is limited mainly to single-institution retrospective studies, which suggest minimal morbidity, technical feasibility, and short-term efficacy comparable to open abdominal sacrocolpopexy. What remains uncertain is whether this approach will be superior to the other established minimally invasive transvaginal and laparoscopic approaches in terms of subjective and objective outcomes and quality of life. Other relevant issues, such as overall cost-effectiveness and extended application for multicompartment defects and uterine-sparing procedures, remain largely unexplored.

SUMMARY

The use of RALS will likely continue to expand secondary to increased access and the popularity of the robotic apparatus among both surgeons and patients. Well designed large randomized multicenter comparative studies based on validated measurement instruments are needed to evaluate its advantage over conventional approaches, including open abdominal sacrocolpopexy and various transvaginal and laparoscopic techniques.

Vaginal prolapse repair using the Prolift kit: a registry of 100 successive cases

OBJECTIVES

To evaluate anatomical, functional outcomes and complications inherent to the treatment of pelvic organ prolapse by implantation of polypropylene mesh, using the Prolift kit.

MATERIALS AND METHODS

Single-center observational study of 100 successive patients enrolled in a registry, who underwent Prolift prolapse repair. Data on prior treatments, associated procedures and per- and post-operative complications were collected and the patients were seen after 2, 6 and 12 months. Anatomical outcomes were assessed using the International Continence Society Pelvic Organ Prolapse Quantification (ICS POP-Q) system. Function was assessed in terms of urinary and digestive problems, and impact on sex life. Failure was defined as relapse of POP-Q Grade 2 or more.

RESULTS

Of the 100 patients, 32 had an anterior, 14 a posterior, 54 a total Prolift; 53 had concomitant urinary incontinence surgery. At 6 and 12 months respectively, 8% and 12% of the patients were lost to follow-up. Mean operating time was 39.8 min. With respect to peri-operative complications, there was no bladder or rectal damage but three patients experienced bleeding (≥ 300 ml) without needing transfusion. POP-Q Grades before surgery were: Grades III-IV cystocele in 65.7% of the anterior Prolift patients; Grades II-III rectocele in the posterior; and 77.8% of total were Grade III and 11.1% Grade IV. The incidence of recurrence was 3.6% at Month 6 and 10.2% at Month 12. Significant (p<0.05) improvements were seen in median scores for the various POP-Q items. With respect to functional problems, stress urinary incontinence was cured in 92% of the patients but 7.7% reported new-onset urinary incontinence after one year. One case of vaginal exposure after one year was observed and major or symptomatic mesh retraction was observed in 8%. New-onset dyspareunia was reported by 11.1% of the patients.

CONCLUSIONS

These results confirm the feasibility of using the Prolift kit in the repair of prolapse via a vaginal approach and the low per- and post-operative morbidity associated with that technique. Nevertheless, longer-term evaluation is required to confirm the results.
