Long-term results following fixation of the vagina on the sacrospinal ligament by the vaginal route (vaginaefixatio sacrospinalis vaginalis)

Bilateral Sacrospinous Vaginal Vault Fixation With Synthetic Mesh Arms: A Novel Technique

Sacrospinous ligament suspension is used for suspension of apical prolapse; however, it has a high rate of recurrence compared with sacrocolpopexy, and a high rate of pain compared with uterosacral suspension. We developed a novel surgical procedure of bilateral sacrospinous vaginal vault fixation with synthetic mesh arms. We previously demonstrated its safety, and in Supplementary video 1, we describe a step-by-step surgical approach that could be replicated. This technique restores support, creating an anatomically correct midline configuration of the vaginal axis with minimal tension. A randomized controlled trial is underway to examine durability of mesh versus suture techniques for sacrospinous ligament suspension.

COMET (Composite Outcomes of Mesh vs suture Techniques for prolapse repair)- Protocol for a single blind randomized controlled multicenter trial testing surgical innovation in female pelvic surgery

BACKGROUND

Pelvic organ prolapse (POP) increases in incidence and severity with aging. At least 1 in 4 women seek pelvic floor care and many more suffer with concurrent symptoms of bowel, bladder and sexual dysfunction, which can have a large impact on quality of life. It is estimated that 1 in 5 women will undergo surgery for POP. POP is difficult to cure with existing surgeries and therefore treatment failure and reoperations are common. Surgical innovation in this area is urgently needed and we have developed a novel technique of bilateral sacrospinous vaginal vault fixation with synthetic mesh arms (BSSVF-M). Based on preliminary studies it may be more successful, durable and cost-effective than standard sacrospinous ligament suspension with sutures (SSLS). Preliminary development and exploration studies showed safety and efficacy of BSSVF-M. Following an established framework for research in surgical innovations, we now wish to conduct a randomized comparative effectiveness trial for assessment of this novel technique.

METHODS

This is a multi-center randomized controlled trial in Canada comparing the surgical techniques of BSSVF-M vs. SSLS to address apical prolapse. In total, 358 women with symptomatic POP at five centers will be randomized with 80% power to detect a 15% difference in primary composite outcome and accounting for a 15% loss to follow-up over 2 years. The primary objective is to investigate BSSVF-M vs. SSLS using an established composite of 3 objective signs and 1 subjective symptom of POP measured 2 years postoperatively. Secondary objectives: 1) To determine changes in condition-specific pelvic symptoms, quality of life, pain and condition-specific body image post BSSVF-M vs. SSLS using validated questionnaires; 2) To determine changes in sexuality post BSSVF-M vs. SSLS; 3) To determine global impression of improvement, adverse events (validated classification scheme), reoperations and health utility post BSSVF-M vs. SSLS; 4) To determine the cost-effectiveness of BSSVF-M vs SSLS. Study Registration at clinicaltrials.gov (NCT02965313).

DISCUSSION

There is a need for innovation to improve the surgical approach to vaginal apical suspension. Despite controversies with mesh, it has been shown to be safe when used appropriately and to have higher durability when compared with sutures. As well, the importance of restoring anatomy and tension-free surgical approach in pelvic reconstructive surgery has led to better long-term outcomes and fewer side effects. These principles have been applied when developing the novel BSSVF-M technique. Anticipated challenges of this trial include recruitment, compliance problems and loss to follow up However, the robust methodology will provide evidence on the best surgical approach to correct POP, a common condition among aging women.

Sacrospinous fixation: Review of relevant anatomy and surgical technique

Apical support is an important component of pelvic floor reconstruction for pelvic organ prolapse. Sacrospinous ligament fixation is a recognized procedure for apical support. Complications from sacrospinous ligament fixation include pain (buttock and leg) and bleeding. There is some debate as to the optimal location for placement of the sacrospinous fixation sutures. This review summarizes the neuroanatomy of the coccygeus sacrospinous ligament as it pertains to the sacrospinous ligament fixation procedure. An appreciation of the neuroanatomy will lead to a better understanding of methods to reduce operative complications and improve suture placement. This paper also describes a technique for the sacrospinous fixation procedure to better assist clinicians in dissecting the connective tissue off the ligament. Removing or clearing the connective tissue off the ligament will allow critical landmarks to be easily palpated and hence a more accurate placement of sutures. This in turn may reduce the risk of perioperative complications.

Manchester Procedure vs Sacrospinous Hysteropexy for Treatment of Uterine Descent: A Randomized Clinical Trial

Importance

In many countries, sacrospinous hysteropexy is the most commonly practiced uterus-preserving technique in women undergoing a first operation for pelvic organ prolapse. However, there are no direct comparisons of outcomes after sacrospinous hysteropexy vs an older technique, the Manchester procedure.

Objective

To compare success of sacrospinous hysteropexy vs the Manchester procedure for the surgical treatment of uterine descent.

Design, Setting, and Participants

Multicenter, noninferiority randomized clinical trial conducted in 26 hospitals in the Netherlands among 434 adult patients undergoing a first surgical treatment for uterine descent that did not protrude beyond the hymen.

Interventions

Participants were randomly assigned to undergo sacrospinous hysteropexy (n = 217) or Manchester procedure (n = 217).

Main Outcomes and Measures

The primary outcome was a composite outcome of success, defined as absence of pelvic organ prolapse beyond the hymen in any compartment evaluated by a standardized vaginal support quantification system, absence of bothersome bulge symptoms, and absence of prolapse retreatment (pessary or surgery) within 2 years after the operation. The predefined noninferiority margin was 9%. Secondary outcomes were anatomical and patient-reported outcomes, perioperative parameters, and surgery-related complications.

Results

Among 393 participants included in the as-randomized analysis (mean age, 61.7 years [SD, 9.1 years]), 151 of 196 (77.0%) in the sacrospinous hysteropexy group and 172 of 197 (87.3%) in the Manchester procedure group achieved the composite outcome of success. Sacrospinous hysteropexy did not meet the noninferiority criterion of -9% for the lower limit of the CI (risk difference, -10.3%; 95% CI, -17.8% to -2.8%; P = .63 for noninferiority). At 2-year follow-up, perioperative outcomes and patient-reported outcomes did not differ between the 2 groups.

Conclusions

Based on the composite outcome of surgical success 2 years after primary uterus-sparing pelvic organ prolapse surgery for uterine descent, these results support a finding that sacrospinous hysteropexy is inferior to the Manchester procedure.

Long-term outcomes of cable-suspended suture technique versus conventional suture for anterior vaginal wall prolapse: a retrospective cohort study

BACKGROUND

Anterior colporrhaphy (AC) is a conventional surgical repair technique for cystocele but with high recurrence rate. We present a novel technique: Cable-suspended structure (CSS) by non-absorbable suture combined with "bridge" formation in surgical treatment of cystocele. This study aimed to evaluate and compare the long-term outcome of CSS technique for anterior vaginal wall repair with AC.

METHODS

A retrospective review was performed on patients who underwent anterior vaginal wall repair between January 2012 and March 2017 at our center. All the patients were under a follow-up survey. The primary outcomes were objective cure (anterior prolapse POP-Q ≤ stage 1) and subjective cure (no symptoms of bulge or retreatment for prolapse). Secondary outcomes included quality of life (QOL) and patients' satisfaction, outcomes of site-specific POP-Q points Aa, Ba and C, as well as postoperative complications.

RESULTS

Of 91 included participants, 43 underwent AC and 48 underwent CSS. The proportion of sarcrospinous ligament fixation in the CSS group was higher than in the AC group (81.4% vs. 77.1%, P < 0.05). At a median follow-up of 69 months, the CSS group showed significantly higher objective cure rate compared with the AC group (72.9% vs. 51.2%, odds ratio 2.57, 95%CI 1.07-6.16). After adjusting for sarcrospinous ligament fixation, the CSS group still significantly showed higher objective cure rate (adjusted odds ratio 2.88, 95%CI 1.16-7.21). The proportion of the patients with POP-Q 0 stage in the CSS group was particularly higher than the AC group (25% vs. 7.0%, P = 0.025). There was no difference between the groups with respect to subjective cure, patients' satisfaction and postoperative complication.

CONCLUSIONS

The CSS technique showed better objective outcome than AC, however, subjective cure rate did not significantly differ between the two. Future prospective trial with large-scale should confirm the effectiveness and safety of CSS in sexually active women.

Female sexual function after repair of uterovaginal prolapse

OBJECTIVE

To evaluate the impact of repair of uterovaginal prolapse using sacrospinous hysteropexy on female sexual function.

METHODS

A cross-sectional study was conducted at the Urogynecology Clinic of the Suez Canal University Hospital from May 2014 to April 2019. Twenty-seven women with a diagnosis of uterovaginal prolapse and wishing to preserve their uteri were recruited. Sacrospinous ligament fixation was done. Sexual symptoms were assessed using the female sexual function index (FSFI) questionnaire just before and 6 months after the operation.

RESULTS

The mean age of the participants was 36.5 ± 4 years. Sacrospinous hysteropexy only was performed for three women. Additional procedures included anterior colporrhaphy (12), posterior colporrhaphy (9), and perineorrhaphy (15). There was a significant improvement in pre- and postoperative patients' orgasm (3.1 ± [0.8] vs. 3.7 ± [1.1]; p value = 0.03) and satisfaction (3.4 ± [0.6] vs. 4.2 ± [0.8]; p value < 0.001) while there was worsening of pain (4.3 ± [1.5] vs. 3.2 ± [1.6]; p value = 0.017). There was insignificant improvement in the other three domains as well as total score of FSFI, with all patients having sexual dysfunction.

CONCLUSION

Sacrospinous hysteropexy was associated with significant improvement orgasm and satisfaction domains of FSFI and significant worsening of pain.

Levator ani and puborectalis muscle rupture: diagnosis and repair for perineal instability

BACKGROUND

Puborectalis muscle rupture usually arises from peri-partum perineal trauma and may result in anterior, middle compartment prolapses, posterior compartment prolapse which includes rectocele and rectal prolapse, with or without associated anal sphincter damage. Patients with puborectalis muscle and levator ani rupture may present some form of incontinence or evacuation disorder, sexual dysfunction or pelvic organ descent. However, the literature on this subject is scarce. The aim of our study was to evaluate management and treatment of functional disorders associated with puborectalis and/or pubococcygei rupture at the level of the insertion in the pubis in a cohort of patients referred to a tertiary care coloproctology center.

METHODS

We conducted a prospective cohort study of patients with levator ani and puborectalis muscle avulsion in the Proctology and Pelvic Floor Unit, Division of Digestive Surgery of the University Hospitals of Geneva from January 2001 to November 2018. Clinical examination, anoscopy and ultrasound were performed on a routine basis. Rupture of the levator ani muscle was diagnosed by clinical examination and ultrasound. A Wexner incontinence score was completed before and 6 months after surgery. Levator ani muscle repair was performed using a transvaginal approach.

RESULTS

Fifty-two female patients (median age 56 ± 11.69 SD years, range 38-86 years) were included in the study. Thirty-one patients (59.6%) had anal incontinence, 25 (48.1%) urinary incontinence, 28 (53.9%) dyschezia (obstructive defecation or excessive straining to defecate), 20 (38.5%) dyspareunia, 17 (32.7%) colpophony, and 13 (25.0%) impaired sensation during sexual intercourse. Deviation of the anus on the side opposite the lesion was observed in 50 patients (96.2%), confirmed with clinical examination and both endoanal and perineal ultrasound. Out of these 52 patients, levator ani rupture (including puborectalis rupture) were categorized into right sided, 43 (82.69%), left sided, 7 (13.46%) and bilateral, 2 (3.85%). Levator ani muscle repair was performed in all patients, associated with posterior repair and levatorplasty in 26 patients (50%) and with sphincteroplasty in 34 patients (63.4%). Four patients (7.7%) experienced postoperative complications: significant postoperative pain (n = 3; 5.77%), urinary retention (n = 2; 3.85%), hematoma (n = 1; 1.92%), and perineal abscess (n = 1; 1.92%). Forty-one patients (78.8%) had full restoration of normal puborectalis muscle function (Wexner score: 0/20) after surgery, and overall, all patients had an improvement in the Wexner score and in sexual function. Dyschezia was reported by 28 patients (53.9%) preoperatively, resolved in 18 (64.3%) and improved by 50% or more in 10 (35.71%).

CONCLUSIONS

Diagnosis of levator ani and puborectalis muscle rupture requires careful history taking, clinical examination, endoanal and perineal ultrasound. Surgical repair improved anal continence as well as sexual function in all patients. Transvaginal levator ani repair seems to be well tolerated with good short-term results.

Vaginal Sacrospinous Ligament Fixation Using Tissue Anchoring System Versus a Traditional Technique for Women With Apical Vaginal Prolapse: A Randomized Controlled Trial

OBJECTIVE

The aim of the study was to compare the efficacy and safety of the tissue anchoring system (TAS) kit versus the traditional technique for sacrospinous ligament fixation (SSLF) to treat apical vaginal wall prolapse.

METHODS

A prospective randomized controlled multicenter study of noninferiority involving women with apical prolapse (C-point≥+1). Primary outcome is surgical success as C-point≤-4 at the 1-year follow-up. Secondary outcomes are success according to the composite criteria as C-point≤-4, Ba-point ≤0, and Bp-point ≤0; POP-Q measures of the vaginal compartments; intraoperative findings, complications; reoperation rate; hospital stay; and quality of life and sexual functioning (PISQ-12). It was estimated that 50 individuals per group would yield an 80% power for a noninferiority margin of 15%.

RESULTS

Ninety-nine women were randomized: TAS (n = 55) and traditional SSLF (n = 44). The groups' preoperative data were similar. Drop-out rate was 11% for 12-month follow-up. Success rates were 90% for TAS and 80% for traditional SSLF (P = 0.0006; absolute difference, 9.8%; 90% confidence interval, -5.2 to 24.8) with the sensivity analyses per-protocol considering only the subjects that completed the 12-month follow-up and 80% versus 73%, respectively (P = 0.0048; absolute difference, 7.3%; 90% confidence interval, -9.6 to 24.2) by sensivity analyses considering the total number of participants randomized and treated with drop-out cases as failure. We detected shorter intraoperative time to dissect and reach the SSL, shorter length of hospitalization, lower rates of urinary tract infection, and lower pain scores in the first 30 days postoperative in the TAS compared with the traditional SSLF groups (P < 0.05). There was an improvement in women's quality of life that did not differ between groups.

CONCLUSIONS

The modified technique of SSLF using the TAS kit is noninferior to the traditional technique for the treatment of apical compartment in 12-month follow-up.

Four-arm polypropylene mesh for vaginal vault prolapse-surgical technique and outcomes

OBJECTIVE

Advanced vaginal vault prolapse (VVP) can occur rarely after any type of hysterectomy. Several types of procedures have been applied to correct this defect, but optimal management is still pending. The aim of this study was to describe the surgical technique and results of four-arm transvaginal mesh (FATVM) application for advanced VVP.

STUDY DESIGN

We followed up for 24 months, 160 patients with VVP > II vc (according to the Pelvic Organ Prolapse Quantification Scale (POPQ)), who underwent FAMTVM from 2014 to2017. FAMTVM was inserted with the anterior arms through the obturator foramens and the posterior arms through the ischiorectal fossas and sacrospinal ligaments. Clinical data were prospectively collected in a customized database and retrospectively analyzed. To assess QoL SF 36, KHQ and FSFI questionnaires were used. POPQ was employed to measure degree of VVP. Non-parametric tests (The Wilcoxon signed-rank test) were applied to verify statistical hypotheses.

RESULTS

According to SF 36, significant improvement was evident in almost all aspects of general QoL (PCS p = 0.002, MCS p = 0.01). KHQ showed statistically significant improvement in all domains. FSFI scores after surgery indicated significantly improvement in all domains of the questionnaire, apart from lubrication (p = 0.02). Intraoperative bladder injury occurred in 3.75 % (n = 6) of all cases. Five patients (3.1 %) complained of de novo stress urinary incontinence. VVP reoccurred in nine cases (5.6 %). Only two patients (1.25 %) saw mesh exposure after 6 months postoperative recovery.

CONCLUSION

We consider FAMTVM for VVP to be safe and effective. Hence, it applied as an optional treatment, especially in patients with contraindications to laparotomy and laparoscopy.

Use of pelvic model-based simulation for sacrospinous ligament fixation education in novice learners: a single-blinded randomized controlled trial

INTRODUCTION AND HYPOTHESIS

We hypothesize that there will be improvement in a novice learners' confidence and skill level with sacrospinous ligament fixation (SSLF) following a pelvic model-based simulation.

METHODS

We performed a single-blinded randomized controlled trial with obstetrics and gynecology residents who were novices at SSLF. The residents were randomly assigned to two groups. The control group received a lecture on the SSLF procedure and anatomy, whereas the intervention group received the same lecture in addition to a pelvic model-based simulation session taught by urogynecologists. The residents' knowledge of SSLF anatomy and confidence level with the procedure were measured via assessments administered before and after the educational interventions. Their technical skills were objectively assessed by one of two fellowship-trained urogynecologists who were blinded to their group allocation.

RESULTS

A total of 28 residents were recruited with 14 residents in each group and equal distribution of junior and senior trainees. None of the residents had previously performed the SSLF procedure. There was no difference in anatomical knowledge between the two groups. The intervention group showed a greater increase in their average confidence score compared with the control group: 4.0 ± 1.4 (95% CI 3.1-4.8) versus 2.6 ± 1.6 (95% CI 1.7-3.4) respectively, with p = 0.02. The intervention group also showed better objective scores in specific technical skills, such as instrument handling (p < 0.001), instrument movement/motion (p < 0.001), and speed (p = 0.01).

CONCLUSION

Our results demonstrate that inclusion of a pelvic model simulation significantly improves confidence and certain technical skills of novice trainees in performing SSLF.

Mesh in POP surgery should be based on the risk of the procedure, not the risk of recurrence

The still unfolding story of mesh use in surgery for pelvic organ prolapse (POP) offers insights into the factors that influence how we interpret evidence in assessing new technology. Our adoption of mesh in prolapse surgery was influenced by a paradigm shift from treating to preventing recurrent prolapse. This shift is largely unsupported by data and fails to account for the added risk associated with mesh use. This commentary explores unconscious factors that influence our interpretation of innovation and proposes a new approach to evaluating new surgical technologies that balances benefit and risk. Counseling patients about treatments using the benefit-risk approach offers a more balanced perspective. Using a formal benefit-risk assessment in the scientific evaluation of treatments will also provide a more balanced approach that supports the scientific process and patients who undergo treatment.

Surgical Updates in the Treatment of Pelvic Organ Prolapse

Pelvic organ prolapse affects approximately 8% of women, and the demand for pelvic organ prolapse surgery is expected to increase by nearly 50% over the next 40 years. The surgical techniques used to correct pelvic organ prolapse have evolved over the last 10 years, with multiple well-designed studies addressing the risks, outcomes, reoperation rates, and optimal surgical approaches. Here we review the most recent evidence on the route of access, concomitant procedures, and synthetic materials for augmenting the repair. Ultimately, this review highlights that there is no optimal method for correcting pelvic organ prolapse and that the risks, benefits, and approaches should be discussed in a patient-centered, goal-oriented approach to decision-making.

Sacrospinous colpopexy using Masson luethy needle holder

OBJECTIVE

Sacrospinous colpopexy (SSC) is a well-known surgical technique to correct apical support defect, however its approach is still challenging. The current study describes an alternative and economic approach for suture placement in the sacrospinous ligament during SSC using Masson luethy needle holder.

STUDY DESIGN

A prospective study was conducted in a tertiary care center. The study recruited women with uterovaginal prolapse or post hysterectomy vaginal vault prolapse scheduled for SSC as a constructive surgery for vaginal superior segment defect. Eligible women were assigned to have SSC using Masson luethy needle holder (Group I) for suture placement in the sacrospinous ligament. The control group (Group II) consisted of a group of patients who had SSC using Deschamps ligature carrier.

RESULTS

By the end of the study, 104 women underwent SSC. (Group I) included 55 women while (Group II) included 49 women. The mean SSC operative time was significantly shorter in (Group I) [109±33min versus 206±67min in (Group II), p<0001], with a mean difference of 10.5min [95% CI, 74-136]. This difference in SSC operative time was due to faster suture placement in (Group I) [47±14min versus 153±46min in (Group II), p<0001]. The mean SSC related operative blood loss was significantly less in (Group I) [582±349ml versus 985±463ml in (Group II), p<0001]. The perioperative complications, recurrence and cure rates were similar in both groups.

CONCLUSION

Using Masson luethy needle holder reduced the difficulty associated with suture placement during SSC and allowed the completion of the procedure within a significantly shorter time.

How to manage peroperative haemorrhage when vaginally treating genital prolapse

Surgery of genital prolapse causes haemorrhagic complications in about 1% of cases. The pelvis is highly vascular and accessing the usual landmarks of vaginal surgery, in particular the sciatic spine, is delicate work. Meticulous dissection of closed spaces is often difficult, and exposure and haemostatic procedures will be challenging in the event of any bleeding complication. When fixing prosthesis to the sacrospinous ligament, the inferior gluteal artery and its coccygeal branch are at risk. Fixation to the sacrospinous ligament must be performed more than 25mm away from the sciatic spine and, if possible, must not transfixiate it. Safe insertion of prosthesis requires sufficient experience, and an adequate learning curve. Being aware of vascular anatomy allows one to understand and treat haemorrhagic incidents. Packing or selective embolization seem to be the two methods to adopt, depending on the severity of bleeding and the conditions of exposure on the one hand, and on the technical resources available for embolization, on the other. Hypogastric ligature appears to be ineffective in this context.

Long-term patient satisfaction with michigan four-wall sacrospinous ligament suspension for prolapse

OBJECTIVE

To describe patient satisfaction after Michigan four-wall sacrospinous ligament suspension for prolapse and identify factors associated with satisfaction.

METHODS

Four hundred fifty-three patients were asked to rate their satisfaction with surgery and complete validated quality-of-life instruments. Postoperative support was extracted from the medical record and assessed when possible. Factors independently associated with patients who were "highly satisfied" were identified with multivariable logistic regression.

RESULTS

Sixty-two percent (242/392) reported how satisfied they were 8.0±1.7 years later. Fifty-seven percent had failed prior prolapse surgery, and 56% had a preoperative prolapse 4 cm or greater beyond the hymen. Ninety percent were satisfied; 76% were "completely" or "very" satisfied and they were considered "highly satisfied" for analysis. Fourteen percent reporting being "moderately" satisfied and they were considered among those "less satisfied." Women with lower scores on the postoperative Pelvic Floor Distress Inventory-20 were more likely to be "highly satisfied." Postoperative anatomic data were available for 67% (162/242) and vaginal support was observed at or above the hymen in 86%. Women with preoperative Baden Walker grade 3 or 4 prolapse were more likely than those with grade 2 prolapse to be "highly satisfied." Women with advanced postoperative prolapse (grade 3 or 4) were less likely and those with grade 2 support were as likely to be "highly satisfied" as those with grade 0 or 1 support.

CONCLUSION

The Michigan four-wall sacrospinous ligament suspension is an anatomically effective approach to vault suspension with a high rate of long-term patient satisfaction. Postoperative vaginal support at the hymen does not negatively affect patient satisfaction.

[Utero-vaginal suspension using a bilateral vaginal anterior sacrospinous fixation with mesh. Preliminary results]

OBJECTIVE

To assess anatomical and functional preliminary results, and safety of a new surgical approach for a combined treatment of pelvic organ prolapse (POP) of anterior and medium compartments, using a mesh attached through the sacrospinous ligaments with the UpHold(®) system (Boston Scientific) and the Capio(®).

MATERIAL AND METHODS

A longitudinal case series of 59 consecutive patients operated between October 2009 and January 2012, by five senior surgeons in a single tertiary unit.

RESULTS

Mean age was 66.9 years. Ten patients (17%) had previous pelvic organ prolapse (POP) surgery. There was no intraoperative complication. Mean follow-up was 12 months. Anatomical success for both anterior and apical compartments, i.e. Ba and C/D point<1, was 93% (52/56). Anatomical results shown correction of cystocele with a mean Ba point from+0.79 cm (range -3 to +8) to -2.35 cm (range -3 to 0), correction of uterine/vaul prolapse with a mean C/D point from+0.14 cm (range -6 to+8) to -7.29 cm (range -9 to -1), and correction of rectocele with a mean Bp point from -0.68 cm (range -3 to 7) to -2.77 cm (range -3 to -1). Two patients required further surgery for mesh exposure (3.5%). One patient had a unilateral pudendal neuropathic pain postoperatively.

CONCLUSION

In the current series, utero-vaginal suspension using a bilateral vaginal anterior sacrospinous fixation with mesh was associated with good anatomical success rates. Prospective, comparative and long-term data are needed.

Sacrospinous ligament fixation for pelvic organ prolapse in the era of vaginal mesh kits

PURPOSE OF REVIEW

To examine the sacrospinous ligament as a point of attachment for pelvic organ prolapse procedures, including vaginal mesh kits.

RECENT FINDINGS

Pelvic surgeons are increasingly employing the sacrospinous ligament as a point of attachment for biologic grafts and synthetic mesh kits during uterovaginal prolapse repairs. These techniques may have introduced a novel set of complications (mesh extrusion, erosion) in addition to those already known to occur in traditional sacrospinous ligament fixations. Except for limited short-term results, little data are available in the literature regarding surgical outcomes and complications for mesh and graft augmented repairs attached to the sacrospinous ligament.

SUMMARY

The sacrospinous ligament fixation is a well tolerated and effective procedure for suspension of the vaginal apex. Mesh augmentation using the sacrospinous ligament may improve objective prolapse recurrence, but complications still occur, including those specific to mesh placement.

The sacrospinous ligament: conveniently effective or effectively convenient?

The sacrospinous ligament has been used for over 50 years as a convenient structure for treating vaginal vault and more recently, uterine prolapse. The procedure has evolved over the years and its efficacy has been hotly debated with invariable comparisons made to abdominal sacral colpopexy. Mesh surgery has introduced a newer dimension to the debate. This review is an attempt to clarify the anatomy, reflect on various techniques and offer a critique on the current 'status' of the sacrospinous ligament.

Is standardised vaginal sacrospinous ligament fixation a safe teaching procedure for residents?

INTRODUCTION AND HYPOTHESIS

Several modifications of sacrospinous ligament fixation (SLF) are described.

METHODS

This study presents a standardised SLF technique. Perioperative course and outcome are compared retrospectively after surgery is performed by experienced surgeons or by residents.

RESULTS

Two hundred three SLF were analysed. Eight residents (LO) operated on 41 patients (5.1 ± 2.2). Six experienced surgeons (SO) operated on 162 patients (27.0 ± 25.7). Mean operating time was 67 ± 33 min. (LO 99 ± 45 min vs. SO 59 ± 22 min, p < 0.05). The overall morbidity rate was 7.8%. There was no significant difference regarding complications and outcomes between SO and LO.

CONCLUSIONS

Operation time was longer but outcomes were identical, and morbidity rate was not increased in the group of resident surgeons. In comparison to literature, complication rate was low. SLF should be part of residency programmes.

Clinical outcome of transvaginal sacrospinous fixation with the Veronikis ligature carrier in genital prolapse

OBJECTIVE

To evaluate the clinical outcome of sacrospinous fixation (SSF) using the Veronikis ligature carrier (VLC) for genital prolapse.

STUDY DESIGN

A retrospective longitudinal study was performed. From December 2003 through June 2008, SSF was performed in 76 patients using the VLC as part of their site-specific reconstructive pelvic surgery. All patients were followed up postoperatively at 6 weeks, 3 months, 6 months, 12 months, and annually thereafter.

RESULTS

The median operative time of SSF was 34min. It took less than 5min to introduce two sutures through the ligament using the VLC. Four patients (5.3%) had recurrent vaginal vault descent at 3-8 months, and received SSF again. Three patients had recurrent stage 1 cystocele at 6-12 months, but did not require further surgery.

CONCLUSION

The VLC allowed effective introduction of the suspending suture through the sacrospinous ligament and might be considered an important surgical component in the treatment of severe genital prolapse.

[Treatment of uterine prolapse and vaginal vault by vaginal route]

All the prolapses of the median compartment (uterine or vault prolapse) of the pelvis have the same physiopathology. The surgical treatment must be reserved to symptomatic patients. Hysterectomy is discussed. The gold standard of the vaginal way is the sacrospinofixation (Richter procedure) Many other procedures are possible: colpofixation or colpocléisis. On young premenopausal women, the abdominal sacrofixation is the gold standard, but in postmenopausal ones, the vaginal way, specially the sacrospinofixation, is quicker and with less morbidity and hospitalization.

[How to manage multicompartment pelvic organe prolapse?]

Repair of pelvic organ prolapse by vaginal route may use native tissues or meshes, which have been in extensive use over the last decades. Traditional surgery, and particularly sacrospinous fixation, has been proven to be effective with long term follow-up with well-known specific risks that could be avoided by skilled surgeons on condition that he observes basic vaginal surgery rules. This surgery is still recommended as first choice in patients over 70 years old with high-grade prolapse. Nevertheless recurrence rate after high-grade cystocele repair using native tissues as been reported between 30 and 50% depending on the technique used. Mesh repair and particularly the use of mesh kits is a valid option in case of prolapse with cystocele behind the hymen, specifically in case of paravaginal defect. Meshes use is licit in patients with prolapse recurrence as well. In contrast, spread use of transvaginal meshes in young patients with grade 3 or 4 prolapse whom tissues have a poor quality, has to be considered very carefully because of the lack of knowledge about long term results and sexual outcome.

[Sexual outcome after pelvic organ prolapse surgery]

Sexual well-being is an important parameter of women's health and quality of live. Sexual disorders may occur in women with pelvic organ prolapse and/or stress urinary incontinence and also after pelvic reconstructive surgery. Sexual dysfunction after POP or SUI surgery has been poorly documented but new condition specific questionnaires have been developed to help us to better evaluate such consequences. This paper reports updated data and highlights more specifically consequences of surgery with mesh reinforcement which is, currently, an important issue particularly when performing by vaginal approach.

Vaginal vault prolapse

Introduction. Vaginal vault prolapse is a common complication following vaginal hysterectomy with negative impact on women's quality of life due to associated urinary, anorectal and sexual dysfunction. A clear understanding of the supporting mechanism for the uterus and vagina is important in making the right choice of corrective procedure. Management should be individualised, taking into consideration the surgeon's experience, patients age, comorbidities, previous surgery and sex life. Result. Preexisting pelvic floor defect prior to hysterectomy is the single most important risk factor for vault prolapse. Various surgical techniques have been advanced at hysterectomy to prevent vault prolapse. Studies have shown the McCall's culdoplasty under direct visualisation to be superior. Vault prolapse repair rely on either the use of patient's tissue or synthetic materials and can be carried out abdominally or vaginally. Sacrospinous fixation and abdominal sacrocolpopexy are the commonly performed procedures, with literature in favour of abdominal sacrocolpopexy over sacrospinous fixation due to its reported higher success rate of about 90%. Other less commonly performed procedures include uterosacral ligament suspension and illiococcygeal fixation, both of which are equally effective, with the former having a high risk of ureteric injury. Colpoclesis will play a greater role in the future as the aging population increases. Mesh procedures are gaining in popularity, and preliminary data from vaginal mesh procedures is encouraging. Laparoscopic techniques require a high level of skill and experience. There are many controversies on the mechanism of prolapse and management techniques, which we have tried to address in this article. Conclusion. As the aging population increases, the incidence of prolapse will also rise, older techniques using native tissue will continue, while new techniques using the mesh needs to be studied further. The later may well be the way forward in future.

[Sexual outcome after pelvic reconstructive surgery]

Sexual well-being is an important parameter of women's health and quality of live. Sexual disorders may occur in women with pelvic organ prolapse and/or stress urinary incontinence and also after pelvic reconstructive surgery. Sexual dysfunction after POP or SUI surgery has been poorly documented but new condition specific questionnaires have been developed to help us to better evaluate such consequences. This paper reports available data and highlights more specifically consequences of surgery with mesh reinforcement which is, currently, an important issue particularly when performing by vaginal approach.

Perioperative course and long term outcome after vaginal sacrospinous colpopexy for vaginal vault prolapse post hysterectomy: comparison of three different suture methods

AIM

To compare long-term results of the vaginal sacrospinous colpopexy (VSC) procedure for the treatment of vaginal vault prolapse after previous hysterectomy with the use of either of the three most commonly used devices (the Deschamps ligature carrier, the Shutt Suture Punch System, or an ordinary straight needle holder).

METHOD

The study group consisted of 73 women (out of 84; response rate 86%) who had undergone VSC for vaginal vault prolapse in between January 1994 and April 2005. All these patients were contacted with a mailed questionnaire and asked about symptoms related to prolapse, possible complications, any subsequent surgical repair and their satisfaction with results of the surgery. All data concerning the patients' characteristics at the time of surgery and perioperative events were retrospectively collected using the patient records (charts).

RESULTS

There were no significant differences in age, parity, body mass index, or in proportion of previous prolapse or incontinence surgery between groups. The operation time was similar in all groups, with a median duration around 60 min. There was a wide distribution of the estimated blood loss in the groups, but without significant differences between groups. The rate of complications was low in all groups. Most of the patients were 'very satisfied' with the results of the surgery and rated their satisfaction as 8 to 10. The proportions of patients being very satisfied with the results of the surgery were 84%, 80% and 87% in the Deschamps, Shutt and needle holder groups, respectively.

CONCLUSION

In the present study we could not see any major differences in perioperative data when comparing usage of the three instruments. Operation time, complications rate, perioperative blood loss and the patient's satisfaction with the surgery were equal between the three groups. This indicates that the type of instrument used in VSC is of no importance.

Functional outcome after sacrospinous hysteropexy for uterine descensus

The study aimed to evaluate urogenital symptoms, defecatory symptoms and quality of life before and after a sacrospinous hysteropexy for uterovaginal prolapse. Seventy-two women with symptomatic uterovaginal prolapse were treated with sacrospinous hysteropexy. Before and after surgery, urogenital and defecatory symptoms and quality of life were assessed with a validated questionnaire. Anatomical outcome was assessed by means of pelvic examination before and after surgery. The mean follow-up time was 12.7 months. Scores on all domains of urogenital symptoms and defecatory symptoms, except for the pain and fecal incontinence domain, improved significantly. Also, quality of life improved on all domains. No major complications were encountered.

Infracoccygeal sacropexy or sacrospinous suspension for uterine or vaginal vault prolapse

OBJECTIVE

To compare infracoccygeal sacropexy (IS) and sacrospinous suspension (SS) for the treatment of uterine or vault prolapse.

METHODS

A randomized trial of 49 women assigned to either the IS group using IVS tape (n=24) or SS group (n=25). Concomitant hysterectomy and repairs were performed as appropriate. Evaluations included prolapse staging using the POP-Q system and validated questionnaires for symptoms (PFDI), quality of life (PFIQ), and sexuality (PISQ-12). The primary outcome measure was postoperative pain.

RESULTS

Patients' characteristics were similar in both groups. IS was quicker, easier, and less painful than SS (P<0.01). Hemorrhage or hematoma rates were similar. Neither rectal injury nor vaginal erosion occurred. Mean follow-up was 16.8 months. Prolapse cure rates, symptom scores, and quality of life were similar. Postoperative cystocele occurred in 4.8% of women after IS and 25% after SS (P>0.05).

CONCLUSION

Infracoccygeal sacropexy is equivalent to sacrospinous suspension, with a decreased rate of postoperative pain and cystocele recurrence.

Bilateral extraperitoneal uterosacral suspension: a new approach to correct posthysterectomy vaginal vault prolapse

Restoration of apical vaginal support remains a challenging problem for the pelvic reconstructive surgeon. The transvaginal use of the uterosacral-cardinal ligament complex is gaining increasing popularity in the surgical treatment of uterovaginal and posthysterectomy vault prolapse. We describe an extraperitoneal surgical approach using this ligamentous complex to reattach the vaginal apex in women with posthysterectomy vault prolapse and report our surgical experience with this procedure in 123 women over 5 years. The relevant anatomy related to the procedure and risk of ureteric injury with uterosacral suspension is also reviewed. Extraperitoneal vault suspension can be combined with the use of polypropylene mesh if required. The extraperitoneal approach is an alternative procedure in women with vault prolapse with or without concomitant enterocele or where access to the Pouch of Douglas is difficult particularly after previous pelvic surgery. We believe this procedure to have less risk of ureteral injury than the intraperitoneal approach.

Suspension du fond du vagin par bandelette transobturatrice postérieure

OBJECTIVE

A study on the feasibility and safety of a new surgical procedure of vaginal vault suspension using a polypropylene mesh placed in the uterovaginal septum by a posterior transobturator approach.

PATIENTS AND METHODS

Longitudinal study from March 2002 to January 2006 of patients treated by this new surgical procedure. Postoperative visits, including an interview and a physical examination were made at two, six and 12 months and annually thereafter. The minimal required follow-up time was 12 months up to January 2007.

RESULTS

Seventy-eight patients were included. Three cases of intraoperative bleeding occurred. In these cases no transfusion was required and no complications were observed later on. The mean hospital stay was five days (range 3-9). The mean follow-up time was 20.36 months (range 12-48). Six recurrences were observed in the medial compartment (8%) and two anterior recurrences (2%). There was no recurrence in the posterior compartment. New-onset moderate dyspareunia was noted in 13% of the cases and a severe in two cases. No erosion occurred.

DISCUSSION AND CONCLUSION

The analysis of our experience shows that vaginal vault suspension by posterior transobturator approach is a safe and simple procedure, and demonstrates its median efficacy. Further, this study should confirm these results over the long-term follow-up.

Heterogeneity in Anatomic Outcome of Sacrospinous Ligament Fixation for Prolapse

OBJECTIVE

To explore why failure rates vary so much between published reports of sacrospinous ligament fixation to correct pelvic organ prolapse and what the potential sources of heterogeneity may be.

DATA SOURCES

MEDLINE was queried for studies between 1966 and 2005 that included the term "sacrospinous."

METHODS OF STUDY SELECTION

One-hundred eighty-seven studies were reviewed. Studies were selected if they 1) involved a surgical procedure performed unilaterally with a posterior or apical vaginal incision and approach to the ligament; 2) reported objective outcomes with a classification system (Baden-Walker, pelvic organ prolapse quantification) over a defined follow-up period; and 3) were published in English, French, or German. Random effects meta-analyses were conducted for both objective and subjective measures of failure.

TABULATION, INTEGRATION, AND RESULTS

Seventeen cohorts met the selection criteria, and the Baden-Walker vaginal profile or a close variation suitable for meta-analysis was used in 10 of them. Variability in failure rates was observed depending on site of and grade of vaginal support (P<.05). The anterior compartment was the most common site of failure for any given grade. This was most striking when the criterion for failure was grade 1 (40.1% anterior, 11.0% apical, 18.2% posterior) or grade 2 prolapse (21.3% anterior, 7.2% apical, 6.3% posterior). Areas of vaginal support were more equally affected when the criterion for failure was grade 3 prolapse (3.7% anterior, 2.7% apical, 2.3% posterior). Among cohorts using grade 2 prolapse as the criterion for objective failure, the pooled measure of failure to relieve symptoms was 10.3% (95% confidence interval 4.4-16.2%) and to provide patient satisfaction was 13.0% (95% confidence interval 7.4-18.6%).

CONCLUSION

The variation in published failure rates after sacrospinous ligament fixation is, in part, accounted for by differences in how anatomical outcomes are evaluated and which compartment of vaginal support is being considered. Failure rates are highest in the anterior compartment.

Study of the biomechanical properties of synthetic mesh implanted in vivo

OBJECTIVE

The objective was to assess in an animal model the mechanical properties of five prostheses used for pelvic floor repair.

STUDY DESIGN

Two months after pre-peritoneal implantation of the five types of prosthesis: Prolene, Prolene Soft, Mersuture, Vicryl and Vypro, we sacrificed the animals to measure retraction of the prosthesis, maximal resistance to traction, and maximal elongation.

RESULTS

Non-absorbable prostheses retracted least. Forces at rupture were disparate with a significant difference in favor of Prolene (p<0.001). Resistance was variably affected by cicatrization. There were no significant differences in elongation.

CONCLUSIONS

This study is an introductory exploration. Monofilament and macroporous propylene prostheses seem, after implantation, to have the best mechanical performance and best tissue integration. This underlines the need for experimental prostheses, which are increasingly used, but still lack the extensive evaluation needed by the surgeon. Knitted polypropylene seems to be one of the best materials at present, but is probably not sufficient.

[Tissue resistance: what about tension-free?]

OBJECTIVES

The purpose is to quantify objective tissue resistances before healing of prostheses used in pelvic floor surgery.

PATIENTS AND METHODS

We measured tissue resistances offered to five types of meshes by four classical surgical routes. We also tested the incidence of the modification of the width of meshes on tissue resistance. This study was realized on frozen cadavers, by pull on prostheses just after implantation. Tests are realized with a dynamometer and results obtained in Newton.

RESULTS

In the Retzius space, TVT offers a better resistance than IVS or LIFT meshes. We did not bring to the fore a significant difference between four routes for 1 cm wide prosthesis. The increase of width of Prolene meshes improves their resistance in tissues and thus quality of their fixation. We underscore a better resistance of the trans sacrospinous route with regard to the trans muscular one.

DISCUSSION AND CONCLUSION

The increase of resistance is bound to the increase of the contact area between the prosthesis and the tissues. This increase of resistance should be taken into account in prolapse surgery: constraints are stronger than for stress incontinence. The posterior arms of meshes have to measure more than 1 cm wide and be set up through the sacrospinous ligament rather than through the elevator muscles. The type of knitting of prostheses is important and influences the resistance in tissues in the immediate postoperative time. Manufacturers should be interested in conceiving specific meshes for the tension-free fixation, with special and adapted mechanical properties.

Long-term outcome of vaginal sacrospinous colpopexy for marked uterovaginal and vault prolapse

BACKGROUND

This study was carried out to evaluate the safety and long-term outcome of sacrospinous colpopexy in marked genital prolapse.

SETTING

Gynaecology Department, Benenden Hospital, Kent, UK.

METHODS

A prospective observational study was conducted between September 1993 and May 2000 on 305 women who underwent transvaginal sacrospinous colpopexy. The indications for surgery were marked vault prolapse in 43% and uterovaginal prolapse or enterocele in 57%. Patient follow up was at 6 weeks, 6 months, 1 year and then annually. Data was collected prospectively at the time of initial recruitment, during hospital stay and at the end of each follow up visit.

RESULTS

Hysterectomy was performed in 117 patients and anterior colporrhaphy in 182. The mean operative time for the entire surgery was 65.6 min (S.D. 27.4, range 20-160 min) and estimated blood loss was 81.8 ml (S.D. 92, range 20-800 ml). After a mean follow up period of 57 months (range 24-84), vault support was maintained in 96%; recurrent vault prolapse occurred in 12 patients (4%) and the mean vaginal length at 1 and 5 years of follow up was 8+/-0.9 and 7.8+/-1.2 cm. Symptomatic cystocele occurred in 15 patients (5%). There were six recurrences of rectocele (2%) and there was no enterocele recurrence. Sexual function was maintained in all sexually active women and 43% reported improvement in sexual function. Out of 14 women who complained of fecal incontinence, 10 (71%) reported cure and 3 (21%) improved after surgery.

CONCLUSIONS

Vaginal sacrospinous colpopexy is associated with a high long-term success rate in correcting upper genital prolapse.

Sacral colpopexy with concurrent Burch colposuspension in patients with vaginal vault prolapse

INTRODUCTION

Abdominal sacral colpopexy (SC) is one option in the management of vaginal vault prolapse. In patients who are additionally incontinent an anti-incontinence procedure such as a Burch colposuspension or pubovaginal sling is usually performed at the same time. For those patients undergoing SC who are continent there are no clear guidelines for the use of a 'prophylactic' anti-incontinence procedure. We describe our experience with SC and concurrent Burch colposuspension.

PATIENTS AND METHODS

47 patients (mean age 65 years) underwent SC and concurrent Burch colposuspension. The preoperative diagnostic check-up included a validated questionnaire, clinical examination, urodynamic tests, ultrasound and colpocystorectography. Patients were also evaluated using Stress, Emptying, Anatomic, Protection and Instability (SEAPI) scores. All patients had a uterine or vaginal vault prolapse in combination with a cystocele, enterocele or rectocele. Thirty-three of 47 (70%) patients were continent and 14 (30%) incontinent. Nineteen (40%) of the 33 'continent' patients were found to have occult incontinence. Clinical examination according to the Halfway system showed 9 of 47 (19%), 21 of 47 (45%) and 17 of 47 (36%) patients with grade 2, 3 and 4 vaginal vault prolapse, respectively. Thirty-five of 47 (74%) patients demonstrated a grade-4 cystocele and 12 of 47 (26%) a grade-3 cystocele. The mean follow-up was 34 months and included a questionnaire (SEAPI), clinical examination and ultrasound.

RESULTS

Postoperative SEAPI scores showed a statistically significant improvement in all SEAPI domains (p < 0.001). Ninety-four percent of the patients were satisfied, continent and would undergo the surgery again. Three patients were incontinent. No continent patient who underwent concurrent Burch colposuspension had obstructive symptoms or residual urine. Five patients (11%) who had dyspareunia preoperatively were free of this symptom postoperatively. Complications were: dilatation of the upper urinary tract in 2 patients (4%) secondary to distal ureteric deviation by suturing the posterior peritoneum. One patient underwent psoas hitch neoureterocystostomy and 1 patient was successfully treated by insertion of a ureteric stent for 6 weeks. One patient (2%) had a mesh infection necessitating removal of the Gore-Tex mesh.

CONCLUSIONS

Sacral colpopexy provides good patient satisfaction, durable pelvic support and restores vaginal function. Due to excellent continence rates concurrent Burch colposuspension should be considered as a joint procedure even in continent patients.

Anatomical conditions for pelvic floor reconstruction with polypropylene implant and its application for the treatment of vaginal prolapse

OBJECTIVE

The purpose of the surgical treatment of vaginal prolapse is not only the restoration of the anatomy but also of the visceral functioning. To maintain the quality of life for patients with recurrent vaginal prolapse, to reduce the failure rates of operations and to avoid a colpectomy or a colpocleisis at the same time, synthetic materials have been introduced in transvaginal reconstructive surgery of the pelvic floor. The TVM Group from France described the reconstruction of the pelvic floor with polypropylene implants in 2004. The aim of this study is to determine the anatomical position of the polypropylene implants after reconstruction of each compartment of the pelvic floor and to determine the relation of the implants to the major neighbouring neurovascular structures on the basis of corpse dissections.

STUDY DESIGN

Following the technique of the TVM Group from France we present the pelvic floor reconstruction using Gynecare Prolift* (Ethicon, Sommerville, NJ, USA). To reach the aims of the study, anatomical dissections of the pelvic floor on three specially preserved anatomical specimens are performed after the placement of the implants.

RESULTS

The anatomical dissections show that every defect in all three compartments of the pelvic floor can be repaired by using polypropylene implants. Between the implants and the major neighbouring neurovascular structures a safe distance exists with slight individual differences.

CONCLUSION

The pelvic floor reconstruction using polypropylene implants is a treatment option especially for the surgical correction of the recurrent vaginal prolapse. If the surgeon has thorough anatomical knowledge and performs the surgical technique in the recommended manner, injuries of the major neighbouring neurovascular structures will be avoided. Clinical studies will analyze the long-term results after pelvic floor reconstruction using polypropylene implants.

[Use of prosthetic materials in reconstructive pelvic floor surgery. An evidence-based analysis]

Many surgical procedures for the repair of pelvic organ prolapse are used nowadays. Reconstructive pelvic surgery continues to evolve while surgeons continue to search the definitive surgical cure and have to choose the most appropriate procedures for their patients. Concerning the vaginal approach procedures, there is an increasing interest in the use of synthetic meshes which are at present widely used for surgical repair of pelvic organ prolapse. Prosthetic repair seems to be more reliable, especially when native tissues are of poor quality. The use of synthetic meshes may also simplify surgical procedures and reduce operative duration and morbidity. Material must be inert, permanent and resistant to infection. Based on authors' and other researchers' published experimental and clinical experience, polypropylene is assumed to be the most appropriate material for the vaginal repair of pelvic organ prolapse. However, since no standardized outcome measure is available, it is difficult to compare the results of surgical procedures. Only in recent studies, the subjective cure rates (patient satisfaction and outcome) have been assessed as well as the objective cure rates determined by the investigators. The subjective cure rate is probably more influenced by the functional outcome and sexual activity than by the anatomical result. Continuous evaluation is necessary to study replacement synthetic materials which should improve the rate of prolapse recurrence and reduce the risk of complications. Randomized controlled trials are required to determine which surgical procedures and type of prosthesis are most suitable. This review evaluates the properties of prosthetic materials, their complications and the most common procedures involved in the use of meshes for pelvic reconstructive surgery.
