Risk of mesh extrusion and other mesh-related complications after laparoscopic sacral colpopexy with or without concurrent laparoscopic-assisted vaginal hysterectomy: experience of 402 patients

Clinician perspectives on hysterectomy versus uterine preservation in pelvic organ prolapse surgery: A systematic review and meta-analysis

BACKGROUND

Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned.

OBJECTIVES

To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair.

SEARCH STRATEGY

MEDLINE and Embase databases were searched from inception to January 2023.

SELECTION CRITERIA

We included randomized and non-randomized studies comparing surgical procedures for POP with or without concomitant hysterectomy. Studies describing open abdominal approaches or transvaginal mesh implantation were excluded.

DATA COLLECTION AND ANALYSIS

A random effect meta-analysis was conducted on extracted data reporting pooled mean differences and odds ratios (OR) between groups with 95% confidence intervals (CI).

MAIN RESULTS

Thirty-eight studies were included. Hysterectomy and uterine-sparing procedures did not differ in reoperation rate (OR 0.93; 95% CI 0.74-1.17), intraoperative major (OR 1.34; 95% CI 0.79-2.26) and minor (OR 1.38; 95% CI 0.79-2.4) complications, postoperative major (OR 1.42; 95% CI 0.85-2.37) and minor (OR 1.18; 95% CI 0.9-1.53) complications, and objective (OR 1.38; 95% CI 0.92-2.07) or subjective (OR 1.23; 95% CI 0.8-1.88) success. Uterine preservation was associated with a shorter operative time (-22.7 min; 95% CI -16.92 to -28.51 min), shorter hospital stay (-0.35 days, 95% CI -0.04 to -0.65 days), and less blood loss (-61.7 mL; 95% CI -31.3 to -92.1 mL). When only studies using a laparoscopic approach for both arms were considered, no differences were observed in investigated outcomes between the two groups.

CONCLUSIONS

No major differences were observed in POP outcomes between procedures with and without concomitant hysterectomy. The decision to preserve or remove the uterus should be tailored on individual factors.

[Radiological imaging following pelvic prolapse surgery]

CLINICAL/METHODICAL ISSUE

Pelvic organ prolapse is a common condition in women, for which both conservative and surgical interventions are available. Knowledge of the different surgical procedures and the materials used is essential for adequate radiological diagnosis after prolapse surgery in order to differentiate potential complications from normal postoperative changes.

STANDARD RADIOLOGICAL METHODS

In the immediate postoperative period, computed tomography (CT) is often the modality of choice for evaluating acute complications such as bleeding or organ injuries. Magnetic resonance imaging (MRI) provides excellent soft tissue contrast and is therefore generally preferred for assessing subacute and chronic complications.

METHODICAL INNOVATIONS

Innovative techniques such as dynamic MRI protocols can improve the radiological assessment after prolapse surgery by enabling the evaluation of organ mobility.

PERFORMANCE

Radiological standard procedures such as computed tomography (CT) and MRI provide detailed and reliable information about the postoperative site and potential complications following prolapse surgery.

ACHIEVEMENTS

Radiological imaging plays an important role in the evaluation of patients after prolapse surgery, particularly when complications are suspected. Accurate radiological diagnosis can guide further appropriate therapeutic measures.

Triple-compartment strategy for abdominal sacral colpopexy using PVDF mesh: one-year report of anatomical and subjective outcomes

INTRODUCTION AND HYPOTHESIS

Abdominal Sacral Colpopexy (ASC) is one of the best surgical methods to repair apical or uterine prolapse. We aimed to evaluate the short-term results of a triple-compartment open ASC strategy using polyvinylidene fluoride (PVDF) mesh in the treatment of patients with severe apical or uterine prolapse.

METHODS

Women with high-grade uterine or apical prolapse with or without cysto-rectocele were prospectively enrolled in the study from April 2015 to June 2021. We performed all-compartment repair using a tailored PVDF mesh for ASC. We assessed the severity of pelvic organ prolapse (POP) using the Pelvic Organ Prolapse Quantification (POP-Q) system at baseline and 12 months after the operation. The patients completed the International Continence Society Questionnaire Vaginal Symptom (ICIQ-VS) questionnaire at baseline, 3, 6, and 12 months postoperatively.

RESULTS

Thirty-five women with a mean age of 59.8±10.0 years were included in the final analysis. Stage III and stage IV prolapse was evident in 12 and 25 patients, respectively. After 12 months, the median POP-Q stage was significantly lower compared to the baseline (4 vs 0, p=<0.0001). Vaginal symptoms score was also reduced significantly at 3-month (7.5±3.5), 6-month (7.3±3.6), and 12-month (7.2±3.1) compared to the baseline (39.5±6.7) (p values < 0.0001). We did not observe any mesh extrusion or high-grade complications. Six (16.7%) patients had cystocele recurrence during the 12-month follow-up, and two of them needed reoperation.

CONCLUSIONS

Our short-term follow-up showed that using an open ASC technique with PVDF mesh in treating high-grade apical or uterine prolapse is associated with a high rate of procedural success and low rates of complication.

Complications of Mesh Sacrocolpopexy and Rectopexy: Imaging Review

Sacrocolpopexy and rectopexy are commonly used surgical options for treatment of patients with pelvic organ and rectal prolapse, respectively. These procedures involve surgical fixation of the vaginal vault or the rectum to the sacral promontory with mesh material and can be performed independently of each other or in a combined fashion and by using an open abdominal approach or laparoscopy with or without robotic assistance. Radiologists can be particularly helpful in cases where patients' surgical histories are unclear by identifying normal sacrocolpopexy or rectopexy mesh material and any associated complications. Acute complications such as bleeding or urinary tract injury or stricture are generally evaluated with CT. More chronic complications such as mesh extrusion or exposure with or without fistulization to surrounding structures are generally evaluated with MRI. Other complications can have a variable time of onset after surgery. Patients with suspected bowel obstruction are generally evaluated with CT. Those with suspected infection, abscess formation, and discitis or osteomyelitis may be evaluated with MRI, although CT evaluation may be appropriate in certain scenarios. The authors review the sacrocolpopexy and rectopexy surgical techniques, discuss appropriate imaging protocols for evaluation of patients with suspected complications, and illustrate the normal appearance and common complications of these procedures. ^© RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Comparison of laparoscopic lateral suspension and laparoscopic sacrocolpopexy with concurrent total laparoscopic hysterectomy for the treatment of pelvic organ prolapse: a randomized controlled clinical trial

INTRODUCTION AND HYPOTHESIS

We compared the outcomes of women who underwent laparoscopic lateral suspension with concurrent total laparoscopic hysterectomy (LLS-TLH) with those of women who underwent laparoscopic sacrocolpopexy with concurrent total laparoscopic hysterectomy (LSC-TLH) for apical and/or anterior vaginal wall prolapse.

METHODS

Eighty women underwent LLS-TLH or LSC-TLH operations. According to the Pelvic Organ Prolapse Quantification System (POP-Q), women with symptomatic pelvic organ prolapse of stage 2 or higher apical and/or anterior compartment prolapse were enrolled in the study. The objective cure rate according to the POP-Q system was the primary (objective) outcome. The International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS), International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), and Patient Global Impression of Improvement (PGI-I) questionnaire scores were the secondary (subjective) outcomes. The primary and secondary outcomes were evaluated at 1 year after surgery.

RESULTS

The primary and secondary outcomes indicated significant improvements in both groups (p < 0.05). The objective cure rate was 92.5% for apical and 78.6% for anterior compartment prolapse in the LLS-TLH group; the respective rates were 100% and 74.1% in the LSC-TLH group. The subjective cure rate was 87.5% for the LLS-TLH group and 90% for the LSC-TLH group. No statistically significant differences between groups were found in the objective cure rate, subjective cure rate, or ICIQ-VS, ICIQ-SF, or PGI-I scores at 1 year (p > 0.05).

CONCLUSIONS

LLS-TLH can serve as a safe, effective, and feasible alternative to LSC-TLH, with low complication rates and similar short-term objective and subjective outcomes.

Rate of Mesh Erosion After Sacrocolpopexy With Concurrent Supracervical Compared With Total Hysterectomy: A Systematic Review and Meta-analysis

OBJECTIVE

To estimate the effect of concomitant supracervical hysterectomy compared with total hysterectomy during abdominal sacrocolpopexy on the rate of mesh erosion by performing a systematic review and meta-analysis of the existing literature.

DATA SOURCES

From database inception through January 2022, we explored MEDLINE, Web of Science, EMBASE, CINAHL, ClinicalTrials.gov , and Cochrane Central Register of Controlled Trials. Studies comparing the rate of mesh erosion in women undergoing abdominal sacrocolpopexy who had concomitant supracervical hysterectomy compared with total hysterectomy were included.

DATA EXTRACTION AND SYNTHESIS

Two reviewers separately ascertained studies, obtained data, and gauged study quality. The rate of mesh erosion was compared, and odds ratios (ORs) with 95% CIs were estimated.

TABULATION, INTEGRATION, AND RESULTS

Nineteen studies with 10,572 women who underwent abdominal sacrocolpopexy were identified, including 4,285 women in the supracervical group and 6,287 women in the total hysterectomy group. The overall mean postprocedure follow-up time was 30.7±15.1 months (median 12.4, range 1.5-44.2). The median (95% CI) point prevalence of mesh erosion was 0.36% (0-1.9%) in women who had supracervical hysterectomy compared with 3.8% (1.8-8.7%) in women who had total hysterectomy. The overall rate of mesh erosion in women who had supracervical hysterectomy was lower compared with women who had total hysterectomy (pooled OR 0.26, 95% CI 0.18-0.38, I 2 0%).

CONCLUSION

In women with symptomatic apical pelvic organ prolapse who undergo abdominal sacrocolpopexy with concomitant hysterectomy, supracervical hysterectomy is associated with a lower risk of mesh erosion compared with total hysterectomy.

Mesh complications after total vs supracervical laparoscopic hysterectomy at time of minimally invasive sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Our objective was to compare mesh exposure rates (4 months and 1 year) after total (TLH) vs supracervical (SLH) laparoscopic hysterectomy at time of minimally invasive sacrocolpopexy (SCP). Secondary outcomes included 30-day complications and midurethral mesh exposure rates.

METHODS

This a retrospective cohort study at a tertiary care referral center from 2011 to 2018. Subjects were identified using Current Procedural Terminology codes. Demographics, operative characteristics, and perioperative complications were abstracted from medical records.

RESULTS

Four hundred three women met the inclusion criteria: 91 SLH+SCP and 312 TLH+SCP. Median follow-up was 52 weeks with an overall mesh exposure rate of 1.5%. Follow-up was available for 90% of patients at 4 months and 51% at 1 year. Half of patients had lightweight mesh (n = 203), and half had ultralightweight mesh (n = 200). Vaginal mesh fixation was performed with permanent suture in 86% (n = 344) and delayed absorbable suture in 14% (n = 56) of patients. At 4 months, vaginal mesh exposure rates did not differ between groups (0% SLH vs 1% TLH, p = 1.00). All mesh exposures in the study period occurred with lightweight mesh in the TLH arm. No differences were noted in 1-year mesh exposure rates, 30-day perioperative complications (p = 0.57), or midurethral mesh exposure rates at 4 months (p = 0.35) and 1 year (p = 1.00) between groups.

CONCLUSIONS

Short-term mesh exposure following SCP with ultralightweight and lightweight polypropylene mesh is rare regardless of type of hysterectomy and much lower than reported in earlier studies with heavier weight mesh. These data suggest TLH at the time of SCP is a safe option in appropriately counseled patients.

Prospective Evaluation of Laparoscopic Sacrocolpopexy with Concomitant Laparoscopic-Assisted Total Vaginal Hysterectomy

(1) Background: Sacrocolpopexy (SCP) with subtotal hysterectomy (SH) is a standard procedure for the treatment of utero-vaginal prolapse. Several disadvantages are associated with the remaining cervix; therefor, SCP with total hysterectomy (TH) may be preferred. According to some publications, SCP with concomitant TH is associated with higher rates of mesh extrusion. Our hypothesis is that mesh extrusion at the apex can be avoided through prevention of thermal injury and through vaginal cuff suturing when performing the laparoscopic sacrocolpopexy combined with a laparoscopic-assisted vaginal total hysterectomy (LAVH). (2) Methods: This prospective cohort study was performed from 2016 until January 2019 including women with a utero-vaginal prolapse undergoing laparoscopic SCP with LAVH. The SCP was performed utilizing a non-absorbable polypropylene macroporous mesh (EndoGYNious®). The primary outcome was the mesh extrusion rate after SCP with concomitant LAVH. The secondary outcome was the objective and functional outcome. (3) There were 50 women included in this prospective cohort. At follow up of 6–12 weeks postoperatively, no mesh extrusion was detected and objectified. Overall, all women showed excellent anatomical and functional outcome. The median time from surgery was 42 months. (4) Laparoscopic SCP with concomitant LAVH showed no increased risk of mesh extrusion and good objective and functional outcomes.

Comparison of the effectiveness of sacrospinous ligament fixation and sacrocolpopexy: a meta-analysis

Introduction and hypothesis

Sacrocolpopexy and sacrospinous ligament fixation (SSLF) have been used for the restoration of apical support. Studies comparing sacrocolpopexy and SSLF have reported conflicting results. We aim to assess the current evidence regarding efficiency and the complications of sacrocolpopexy compared with SSLF.

Methods

We searched PubMed, Embase, and Cochrane Library and performed a systematic review meta-analysis to assess the two surgical approaches.

Results

5Five randomized controlled trials, 8 retrospective studies, and 2 prospective studies including 4,120 cases were identified. Compared with abdominal sacrocolpopexy (ASC), SSLF was associated with a lower success rate (88.32% and 91.45%; OR 0.52; 95% CI 0.29–0.95; p = 0.03), higher recurrence (11.58% and 8.32%; OR 1.97; 95% CI 1.04–3.46; p = 0.04), and dyspareunia rate (14.36% and 4.67%; OR 3.10; 95% CI 1.28–7.50; p = 0.01). Patients in this group may benefit from shorter operative time (weighted mean difference −25.08 min; 95% CI −42.29 to −7.88; p = 0.004), lower hemorrhage rate (0.85% and 2.58%; OR 0.45; 95% CI 0.25–0.85; p = 0.009), wound infection rate (3.30% and 5.76%; OR 0.55; 95% CI 0.39–0.77; p = 0.0005), and fewer gastrointestinal complications (1.33% and 6.19%; OR 0.33; 95% CI 0.15–0.76; p = 0.009).

Conclusion

Both sacrocolpopexy and SSLF offer an efficient alternative to the restoration of apical support. When anatomical durability and sexual function is a priority, ASC may be the preferred option. When considering factors of mesh erosion, operative time, gastrointestinal complications, hemorrhage, and wound infections, SSLF may be the better option.

Pelvic organ prolapse and uterine preservation: a cohort study (POP-UP study)

Background

Abdominal and laparoscopic sacro-colpopexy (LSC) is considered the standard surgical option for the management of a symptomatic apical pelvic organ prolapse (POP). Women who have their uterus, and for whom an LSC is indicated, can have a laparoscopic sacro-hysteropexy (LSH), a laparoscopic supra-cervical hysterectomy and laparoscopic sacro-cervicopexy (LSCH + LSC) or a total laparoscopic hysterectomy and laparoscopic sacro-colpopexy (TLH + LSC). The main aim of this study was to compare clinical and patient reported outcomes of uterine sparing versus concomitant hysterectomy LSC procedures.

Methods

A retrospective analysis of clinical, imaging and patient reported outcomes at baseline, 3 and 12 months after LSH versus either LSCH + LSC or TLH + LSC between January 2015 and January 2019 in a tertiary referral urogynecology center in Pilsen, the Czech Republic.

Results

In total, 294 women were included in this analysis (LSH n = 43, LSCH + LSC n = 208 and TLH + LSC n = 43). There were no differences in the incidence of perioperative injuries and complications. There were no statistically significant differences between the concomitant hysterectomy and the uterine sparing groups in any of the operative, clinical or patient reported outcomes except for a significantly lower anterior compartment failure rate (p = 0.017) and higher optimal mesh placement rate at 12 months in women who had concomitant hysterectomy procedures (p = 0.006).

Conclusion

LSH seems to be associated with higher incidence of anterior compartment failures and suboptimal mesh placement based on postoperative imaging techniques compared to LSC with concomitant hysterectomy.

Short-Term Outcomes of Vaginal Hysterectomy at the Time of Robotic Sacrocolpopexy

OBJECTIVE

With the introduction of robotic sacrocolpopexy (RSC) at our institution in 2008, we noted a reduction in residents' vaginal hysterectomy (VH) experience. In 2012, we made a transition to perform VH on all robotic sacrocolpopexies. Our objective was to report our short-term outcomes and adverse events.

METHODS

In this case series, we evaluated women who underwent VH with concomitant RSC for stages II to IV pelvic organ prolapse between 2012 and 2017. In these cases, the vesicovaginal and rectovaginal spaces were developed transvaginally. Descriptive analysis including demographics, short-term outcomes, and adverse events are reported.

RESULTS

In this group of 209 women, median (interquartile interval) duration of follow-up was 49 (26-60) weeks. The majority of the women were white (84.7%) and postmenopausal (80.9%), with a mean (SD) age of 59 (9) years. At a median follow-up time of 49 weeks, pelvic organ prolapse quantification revealed 20 patients (12.4%) with Ba or Bp greater or equal to 0 and 1.4% of patients required repeat prolapse surgery. Among 9 women (4.3%) with postoperative fever, 4 (1.9%) were treated for pelvic collection/abscess. Of 5 women (2.4%) who had venous thromboembolism, 3 (1.4%) were diagnosed with pulmonary embolism. There were 18 patients (8.6%) treated for urinary tract infection within 6 postoperative weeks. Mesh exposure was noted in 16 (7.7%) of the patients, and 11 (6.2%) required reoperation.

CONCLUSIONS

Vaginal hysterectomy at the time of RSC may increase the risk of infection and mesh exposure compared with procedures without concomitant hysterectomy.

Short and middle-term outcomes of vaginally assisted laparoscopic sacropolpopexy

OBJECTIVE

Vaginally assisted laparoscopic sacrocolpopexy (VALS), which is a combined surgical approach where a vaginal hysterectomy is initially performed, followed by transvaginal placement of synthetic mesh and laparoscopic suspension, can be an alternative to overcome the dissection, suturing limitations of laparoscopic sacrocolpopexy. The aim of this study was to compare the operative times and middle-term anatomic outcomes of women with uterovaginal prolapse undergoing VALS with those of women undergoing abdominal sacrocolpopexy.

METHODS

This is a prospective cohort study that evaluates operation times, anesthesia times, estimated blood loss, middle-term outcomes, perioperative and postoperative complications. We compared the results of 47 women who had the VALS to that of 32 abdominal sacrocolpopexy (AS).

RESULTS

The mean follow up was 22.4 months for AS group and 20.5 months for VALS group. The VALS group (median 1 day) had shorter hospitalization duration than the AS group (median 3 days). The mean operation time was significantly shorter in the VALS group (125.9 minutes) than the AS group (151.9 minutes) (P = .03). There was no significant difference in perioperative and postoperative complication rates. Objective failure rate (8.5% in VALS, 15.6% in AS), subjective failure rates (6.4% in VALS, 9.4% in AS), recurrence (2.1% in VALS, 9.4% in AS) and mesh exposition rates (2.1% in VALS, 9.4% in AS) were similar in both procedures.

CONCLUSIONS

VALS with shorter operative time and hospitalization than conventional AS is a promising modification minimally invasive technique for sacrocolpopexy especially for those inexperienced in laparoscopic sacrocolpopexy.

Management of Vaginal Mesh Exposures Following Female Pelvic Reconstructive Surgery

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

Securing Mesh with Delayed Absorbable Suture Does Not Increase Risk of Prolapse Recurrence After Robotic Sacral Colpopexy

Introduction and Objective: Nonabsorbable monofilament suture is traditionally used to secure vaginal mesh for robot-assisted sacral colpopexy (RASC) but can become exposed postoperatively requiring invasive vaginal removal. Polydioxanone delayed absorbable suture may avoid this. We sought to determine the objective and subjective impact of suture choice for mesh fixation. Materials and Methods: A cohort study was undertaken using a prospective registry and subjects were grouped based on type of suture at the time of RASC. Apical failure was defined as C point descent of >2 cm, anterior compartment failure was defined as pelvic organ prolapse quantification (POP-Q) Ba point of >0, and posterior compartment failure was defined as Bp point of >0. Patient-reported outcomes included urogenital distress inventory (UDI)-6 and QoL. Two-tailed t-test and chi-squared were used for analysis. Results: A total of 119 women underwent RASC between 2009 and 2016. Patients had similar preoperative characteristics (Table 1). All POP-Q, UDI-6, and quality of life (QoL) scores improved postoperatively (Tables 1 and 2). Apical failure was noted in 0, anterior failure was noted in 7 (average Ba +1.1 cm in failures), and posterior failure was noted in 4 (mean Bp +1.0 cm) at 16 months' follow-up. Failures in the anterior compartment were much more common in the nonabsorbable monofilament cohort (Table 2). Failures in the apical and posterior compartments were not significantly different between groups. Nine suture erosions were noted in the nonabsorbable monofilament cohort, five requiring excision in the clinic and two in the operating room. Two suture erosions were noted in the delayed absorbable cohort, 0 required excision. Postoperative UDI-6 and QoL scores did not vary significantly between groups (5.3 ± 4.0 vs 5.1 ± 4.0, p = not significant (NS), 2.8 ± 2.0 vs 2.8 ± 2.2, p = NS). [Table: see text] [Table: see text] Conclusion: Securing mesh with delayed absorbable monofilament did not appear to increase risk of failure in patients undergoing RASC and eliminates the need for suture excision postoperatively.

Comparison between laparoscopic sacrocolpopexy with hysterectomy and hysteropexy in advanced urogenital prolapse

INTRODUCTION AND HYPOTHESIS

The aim of this study was to compare the outcomes in women who underwent laparoscopic sacrocolpopexy (LSC) with or without hysterectomy for pelvic organ prolapse (POP).

METHODS

This was a single-centre prospective study. We included women with symptomatic POP (III-IV stage) who underwent LSC with or without hysterectomy. The preoperative evaluation included a history, clinical examination and urodynamic test; all patients completed FSFI, UDI-6 and IIQ-7 questionnaires. They were followed up at 1, 3, 6 and 12 months after surgery and then annually thereafter with the same preoperative flow chart. At the last visit, they also completed the PGI-I questionnaire.

RESULTS

Between 2012 and 2016, a total of 136 patients with POP were included (82 in the LSC with hysterectomy group and 54 in the hysteropexy group). At a median follow-up of 65.3 months (36-84 months), there were improvements in the anatomical and functional outcomes of both groups without differences between the two approaches. The apical success rate was 100% in all women, without recurrence in either group; the anterior and posterior success rates of hysterectomy were higher than those of uterine preservation.

CONCLUSION

This study showed that there were no differences in the anatomical and functional outcomes between LSC with or without hysterectomy for POP.

Risk factors for vaginal mesh erosion after sacrocolpopexy in Korean women

Objective

Although sacrocolpopexy (SCP) can provide durable apical support, the use of mesh may give rise to various complications, including vaginal mesh erosion. The aim of this study was to identify the risk factors for vaginal mesh erosion after SCP in Korean women.

Methods

This retrospective cohort study included 363 women who underwent SCP with type 1 polypropylene mesh. They were evaluated at 1, 4, and 12 months after surgery and then annually thereafter with respect to anatomy and complications. Univariate and multivariate analyses using the Cox proportional hazard model were performed to identify the risk factors for mesh erosion.

Results

During the median 2-year follow-up period, vaginal mesh erosion was found in 29 women (8.0%). Among them, 19 (65.5%) required surgical correction. Estrogenic status was the only independent risk factor for mesh erosion. The risk for mesh erosion was 4.5 times higher in premenopausal women than in menopausal women not on estrogen replacement therapy (ERT) (95% confidence intervals [CI] 1.9–10.9, p<0.01). Menopausal women on ERT also had an increased risk, with a statistically marginal significance (hazard ratio 2.5, 95% CI 0.9–6.6; p = 0.07).

Conclusions

Premenopausal or menopausal women on ERT are at high risk for mesh erosion after SCP with type 1 polypropylene mesh, and two-thirds of mesh erosion cases require reoperation. This information should be incorporated into patient counseling and treatment decisions.

Current surgical management of pelvic organ prolapse: Strategies for the improvement of surgical outcomes

There are a variety of surgical management strategies to help surgeons repair pelvic organ prolapse (POP). Surgical treatment for POP includes native tissue repair, augmentation with mesh, and minimally invasive surgeries. Currently, laparoscopic or robotic techniques for POP repair are increasing in popularity and continuing to evolve. The aim of this review is to present an up-to-date review of surgical techniques used for POP repair and to discuss ways to optimize surgical outcomes.

Laparoscopic complete sacrocolpopexy mesh removal for right-sided gluteal pain and recurrent mesh erosion

AIM OF VIDEO

The aim was to demonstrate laparoscopic complete excision of sacrocolpopexy mesh from a 65-year-old woman who had presented with delayed onset of persistent right-sided gluteal pain.

METHOD

The patient was referred to our unit, having undergone a laparoscopic sacrocolpopexy for vault prolapse 7 years earlier, with a type 1 polypropylene mesh. Four years after the primary surgery, she first noticed symptoms of spontaneous vaginal pain together with deep dyspareunia, and right-sided gluteal pain. Clinical examination revealed mesh erosion at the vaginal vault. This was managed at her local hospital, with excision of the small exposed portion of the mesh and over sewing, from a vaginal approach. She continued to be symptomatic following this procedure. When her symptoms still failed to improve 3 years later, a tertiary referral was made to our unit. At laparoscopy, minimal adhesions between the bowel and the mesh were noted and divided. After carefully dissecting the right ureter and reflecting the bladder, the entire sacrocolpopexy mesh was removed with its ProTack fasteners. The entire specimen was retrieved in one piece through the open vault and the vagina was sutured with 2.0 <monocryl laparoscopically. Surgical steps begin with laparoscopic survey of the anatomy. Adhesions need to be released carefully, after developing proper surgical planes. On follow-up in clinic 12 weeks later, there was complete resolution of her symptoms, with minimal vault descent.

CONCLUSION

This video demonstrates the steps needed to undertake complete laparoscopic sacrocolpopexy mesh excision, which should be feasible for skilled laparoscopists. This approach has advantages over the open approach, with good access and visualisation of the entire course of the mesh, and more rapid recovery for the patient.

Long-term mesh erosion rate following abdominal robotic reconstructive pelvic floor surgery: a prospective study and overview of the literature

Introduction and hypothesis

The use of synthetic mesh in transvaginal pelvic floor surgery has been subject to debate internationally. Although mesh erosion appears to be less associated with an abdominal approach, the long-term outcome has not been studied intensively. This study was set up to determine the long-term mesh erosion rate following abdominal pelvic reconstructive surgery.

Methods

A prospective, observational cohort study was conducted in a tertiary care setting. All consecutive female patients who underwent robot-assisted laparoscopic sacrocolpopexy and sacrocolporectopexy in 2011 and 2012 were included. Primary outcome was mesh erosion. Preoperative and postoperative evaluation (6 weeks, 1 year, 5 years) with a clinical examination and questionnaire regarding pelvic floor symptoms was performed. Mesh-related complications were assessed using a transparent vaginal speculum, proctoscopy, and digital vaginal and rectal examination. Kaplan–Meier estimates were calculated for mesh erosion. A review of the literature on mesh exposure after minimally invasive sacrocolpopexy was performed (≥12 months’ follow-up).

Results

Ninety-six of the 130 patients included (73.8%) were clinically examined. Median follow-up time was 48.1 months (range 36.0–62.1). Three mesh erosions were diagnosed (3.1%; Kaplan–Meier 4.9%, 95% confidence interval 0–11.0): one bladder erosion for which mesh resection and an omental patch interposition were performed, and two asymptomatic vaginal erosions (at 42.7 and 42.3 months) treated with estrogen cream in one. Additionally, 22 patients responded solely by questionnaire and/or telephone; none reported mesh-related complaints. The literature, mostly based on retrospective studies, described a median mesh erosion rate of 1.9% (range 0–13.3%).

Conclusions

The long-term rate of mesh erosion following an abdominally placed synthetic graft is low.

Short-term Outcomes of Non-robotic Single-incision Laparoscopic Sacrocolpopexy: A Surgical Technique

STUDY OBJECTIVE

Our main purpose was to describe the surgical technique and short-term outcomes of single-incision laparoscopic sacrocolpopexy (S-LSC) for the treatment of pelvic organ prolapse (POP).

DESIGN

This study consisted of a retrospective analysis of 49 consecutive cases.

SETTING

This study was set at the Third Affiliated Hospital of Guangzhou Medical University from October 2016 to November 2017.

PATIENTS

The population for this study consisted of women with stage II to IV POP who met eligibility criteria for laparoscopic surgery.

INTERVENTIONS

S-LSC included the use of V-loc barbed suture and retroperitoneal tunneling, in addition to standard single-incision laparoscopic surgery techniques. All 49 cases were successfully completed. All cases included concomitant procedures; 42 (85.7%) had removal of the uterus and adnexa. The main measured outcomes include patient characteristics, perioperative outcomes, and change in pelvic floor support (Pelvic Organ Prolapse Quantification System), and quality of life (Pelvic Floor Impact Questionnaire).

MEASUREMENTS AND MAIN RESULTS

All patients were parous, and 42.9% had a history of previous abdominal surgery. The mean operative duration from skin to skin was 201.20 ± 46.53 minutes. The mean estimated blood loss was 27.0 ± 16.6 mL. The mean pre- and post-operative Pelvic Organ Prolapse Quantification System scores were 2.2 ± 1.1 cm versus -2.6 ± 0.5 cm for the Aa point and 3.2 ± 2.8 cm versus -4.6 ± 0.8 cm for the C point (p <.05 for both). The mean pre- and post-operative Pelvic Floor Impact Questionnaire scores were 106.4 ± 18.9 versus 8.9 ± 4.26 (p <.05), suggesting that S-LSC significantly improved physical prolapse and quality of life. Four patients suffered from postoperative complications (3 mesh exposure and 1 lumbosacral pain). Six patients complained of new onset of stress urinary incontinence.

CONCLUSIONS

Single-incision laparoscopic sacrocolpopexy is a feasible method to manage POP. However, the long-term effects and complications need to be further investigated.

Effect of modified laparoscopic hysterectomy on pelvic floor function: A retrospective observational study

Hysterectomy is a potential risk factor for subsequent surgery for pelvic organ prolapse, especially when the prolapse exists before hysterectomy. Women without prolapse before hysterectomy may also experience prolapse after hysterectomy. This study aimed to describe a surgical modification of laparoscopic colposuspension with round ligaments after hysterectomy in women without preexisting genital prolapse and to evaluate the initial surgical results in these patients.We reviewed data of 54 patients who underwent laparoscopic hysterectomy with colposuspension with unilateral or bilateral round ligaments after hysterectomy at Chia-Yi Chang Gung Memorial Hospital from July 2012 to March 2015. Vaginal length was measured before and after colposuspension after complete hysterectomy. Preoperative characteristics of the patients, perioperative quality, postoperative outcomes, and vaginal length differences were analyzed.Vaginal length increased by a mean of 2.59 cm after colposuspension. The mean extra-operative time needed for laparoscopic colposuspension was about 10 minutes. No severe complications were reported in our patients, and we did not find any cystocele after completing vaginal cuff suspension to the round ligament.The vaginal apex level was maintained in our modified laparoscopic hysterectomy. Therefore, laparoscopic colposuspension with round ligaments is a promising option as a routine, first-line standard procedure in younger women without genital prolapse to maintain an acceptable vaginal length after laparoscopic hysterectomy.

Surgical management of mesh infection following laparoscopic sacrocolpopexy and tension-free vaginal mesh surgery: a report of two cases with a literature review

Introduction

The standard management for pelvic abscess or spondylodiscitis after reconstructive surgery previously involved total mesh excision, abscess drainage, and intravenous antibiotic administration. However, only few reports exist regarding the possibility of nonoperative management.

Case presentation

Postoperative mesh infection occurred in two cases of transvaginal mesh and laparoscopic sacrocolpopexy surgery for pelvic organ prolapse. In the first case, intravenous antibiotics were administered and debridement was performed. In the second case, intravenous antibiotics were administered, and local drainage was performed postoperatively, as sacral promontory infiltration was suspected. Diabetes was a comorbidity in both cases.

Conclusion

It is necessary to select patients suitable for vaginal or laparoscopic mesh placement for pelvic organ prolapse preoperatively on the basis of prior history of the patients and once the patients provide informed consent for surgery after being explained the possible complications of pelvic reconstructive surgery, such as mesh infection.

Uterus preservation is superior to hysterectomy when performing laparoscopic lateral suspension with mesh

Introduction and hypothesis

We aimed to compare differences between laparoscopic lateral suspension with mesh (LLS) performed with supracervical hysterectomy (LLSHE) and without hysterectomy (LLSUP).

Methods

We retrospectively collected data from women operated by a single surgeon between 2003 and 2011. From a total of 339 women with symptomatic anterior and/or apical pelvic organ prolapse (POP) and an intact uterus, 224 had LLSUP (70.4%) and 94 had LLSHE (29.6%). Three hundred and sixteen patients were examined at 1 year. Primary outcomes were objective and subjective success at 1 year during clinical evaluation. Secondary outcomes were complications (Clavien-Dindo scale) and mesh exposure. Patient satisfaction was evaluated by telephone interview using a 10-point scale and the Patient Global Impression of Improvement Scale (PGI-I).

Results

LLSUP and LLSHE did not differ for age (mean 57 and 55 years, respectively), preoperative status, complications, and participation at the interview (52 vs 53%). LLSHE is associated with higher mesh exposure (6.5 vs 1.3%, p = 0.014) and more frequent use of Mersilene. Titanium-coated and noncoated polypropylene was more frequently used in LLSUP. At 1 year, both anatomic success rate for the anterior compartment (98.7 vs 94.6%, p = 0.021) and subjective success rate (83.5 vs 72.8%, p = 0.035) were higher for LLSUP. Without hysterectomy, patients more often improved (90.5 vs 76.5%, p = 0.013) and would more frequently recommend the procedure (94.5 vs 80.4%, p = 0.004).

Conclusions

LLS with or without hysterectomy is a safe technique with high patient satisfaction. The uterus-preserving approach appears to result in better anatomic outcome for the anterior compartment, better subjective outcome, and higher patient satisfaction.

Polypropylene Mesh Predicts Mesh/Suture Exposure After Sacrocolpopexy Independent of Known Risk Factors: A Retrospective Case-Control Study

OBJECTIVE(S)

The aim of this study was to determine if ultralightweight polypropylene mesh reduced the risk of mesh/suture exposure after sacrocolpopexy compared with heavier-weighted polypropylene.

METHODS

Bivariate and multivariate analyses were used to interpret data from 133 cases and 261 control subjects to evaluate independent predictors of mesh/suture exposure after sacrocolpopexy from 2003 to 2013.

RESULTS

Multivariate logistic regression revealed that prior surgery for incontinence (odds ratio [OR], 2.87; 95% confidence interval [CI], 1.19-6.96), porcine acellular cross-linked collagen matrix with medium-weight polypropylene mesh (OR, 4.95; 95% CI, 1.70-14.42), other polypropylene mesh (OR, 6.73; 95% CI, 1.12-40.63), nonabsorbable braided suture for vaginal mesh attachment (OR, 4.52; 95% CI, 1.53-15.37), and immediate perioperative complications (OR, 3.64; 95% CI, 1.53-13.37) were independent risk factors for mesh/suture exposure. After multivariate analysis, ultralightweight polypropylene mesh was no longer associated with decreased rates of mesh/suture exposure after controlling for known risk factors identified during bivariate analysis (P = 0.423).

CONCLUSIONS

Both mesh choice and suture selection remained independent predictors of mesh/suture exposure, with heavier meshes increasing and monofilament suture decreasing rates of mesh/suture exposure. Based on this study, surgeons may consider use of delayed-absorbable, monofilament suture over nonabsorbable braided suture for attachment of vaginal mesh to reduce the risk of mesh/suture exposure when using mesh.

From intraperitoneal onlay mesh repair to preperitoneal onlay mesh repair

Laparoscopic repair for ventral and incisional hernias was first reported in the early 1990s. It uses intraperitoneal only mesh placement to achieve a tension-free repair of the hernia. However, in recent years, there has been greater concern about long-term complication involving intraperitoneal mesh placement. Many case reports and case series have found evidence of mesh adhesion, mesh fistulation, and mesh migration into hollow organs including the esophagus, small bowel, and large bowel, resulting in various major acute abdominal events. Subsequent management of these complications may require major surgery that is technically demanding and difficult; in such cases, laparotomy and bowel resection have often been performed. Because of these significant, but not common, adverse events, many surgeons favor open sublay repair for ventral and incisional hernias. Investigators are therefore searching for a laparoscopic approach for ventral and incisional hernias that might overcome the mesh-induced visceral complications seen after intraperitoneal only mesh placement repair. Laparoscopic preperitoneal onlay mesh is one such approach. This article will explore the fundamental of intraperitoneal only mesh placement and its problems, the currently available peritoneal visceral-compatible meshes, and upcoming developments in laparoscopic ventral and incisional hernia repair. The technical details of preperitoneal onlay mesh, as well as its potential advantages and disadvantages, will also be discussed.

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.

Risk Factors for Mesh Exposure after Transvaginal Mesh Surgery

Background:

Mesh exposure after surgery continues to be a clinical challenge for urogynecological surgeons. The purpose of this study was to explore the risk factors for polypropylene (PP) mesh exposure after transvaginal mesh (TVM) surgery.

Methods:

This study included 195 patients with advanced pelvic organ prolapse (POP), who underwent TVM from January 2004 to December 2012 at the First Affiliated Hospital of Chinese PLA General Hospital. Clinical data were evaluated including patient's demography, TVM type, concomitant procedures, operation time, blood loss, postoperative morbidity, and mesh exposure. Mesh exposure was identified through postoperative vaginal examination. Statistical analysis was performed to identify risk factors for mesh exposure.

Results:

Two-hundred and nine transvaginal PP meshes were placed, including 194 in the anterior wall and 15 in the posterior wall. Concomitant tension-free vaginal tape was performed in 61 cases. The mean follow-up time was 35.1 ± 23.6 months. PP mesh exposure was identified in 32 cases (16.4%), with 31 in the anterior wall and 1 in the posterior wall. Significant difference was found in operating time and concomitant procedures between exposed and nonexposed groups (F = 7.443, P = 0.007; F = 4.307, P = 0.039, respectively). Binary logistic regression revealed that the number of concomitant procedures and operation time were risk factors for mesh exposure (P = 0.001, P = 0.043).

Conclusion:

Concomitant procedures and increased operating time increase the risk for postoperative mesh exposure in patients undergoing TVM surgery for POP.

Minimally Invasive Sacrocolpopexy: How to Avoid Short- and Long-Term Complications

Sacrocolpopexy remains the "gold standard" procedure for management of posthysterectomy vaginal vault prolapse with improved anatomic outcomes compared to native tissue vaginal repair. Despite absence of clinical data, sacrocolpopexy is increasingly being offered to women as a primary treatment intervention for uterine prolapse. While reoperation rates remain low, recurrent prolapse and vaginal mesh exposure appear to increase over time. The potential morbidity associated with sacrocolpopexy is higher than for native tissue vaginal repair with complications including sacral hemorrhage, discitis, small bowel obstruction, port site herniation, and mesh erosion. Complications are more common during the learning curve of minimally invasive sacrocolpopexy. Appropriate case selection is paramount to balancing the potential for prolapse recurrence with the risk of surgical complications. Use of ultra-lightweight polypropylene mesh and vaginal mesh attachment with delayed absorbable suture may reduce the risks of vaginal mesh exposure.

Conservative management of pelvic abscess following sacrocolpopexy: a report of three cases and review of the literature

INTRODUCTION AND HYPOTHESIS

After sacrocolpopexy, intra-abdominal pelvic abscesses are often managed with intravenous antibiotics, excision of the mesh involved, and debridement of compromised tissue.

METHODS AND RESULTS

Three cases of successful management of pelvic abscesses after sacrocolpopexy using long-term antibiotics and percutaneous drainage of intra-abdominal abscesses without removing the mesh are presented.

CONCLUSIONS

In selected patients who have undergone sacrocolpopexy, with careful counseling, conservative management of pelvic abscesses with percutaneous drainage and long-term antibiotic treatment without the surgical excision of the mesh may play a role.

Native tissue repair for central compartment prolapse: a narrative review

Central descent due to a level 1 defect is a main component in pelvic organ prolapse (POP) reconstructive surgery, whether for symptomatic apical prolapse or for the prolapse repair of other compartments. A recent growth in the rate of native tissue repair procedures for POP, following the US Food and Drug Administration (FDA) warnings regarding the safety and efficacy of synthetic meshes, requires a re-evaluation of these procedures. The safety, efficacy, and determination of the optimal surgical approach should be the center of attention. Functional outcome measures and patient-centered results have lately gained importance and received focus. A comprehensive literature review was performed to evaluate objective and subjective outcomes of apical prolapse native tissue repair, with a special focus on studies reporting impact on patients' functional outcomes, quality of life, and satisfaction. We performed a MEDLINE search for articles in the English language by using the following key words: apical prolapse, sacrospinous ligament fixation, uterosacral ligament suspension, sacral colpopexy, McCall culdoplasty, iliococcygeus vaginal fixation, and functional outcomes. We reviewed references as well. Despite a prominent shortage of studies reporting standardized prospective outcomes for native tissue repair interventions, we noted a high rate of safety and efficacy, with a low complication rate for most procedures and low recurrence or re-treatment rates. The objective and subjective results of different procedures are reviewed. Functional outcomes of native tissue repair procedures have not been studied sufficiently, though existing data present those procedures as favorable and not categorically inferior to sacrocolpopexy. Apical compartment prolapse repair using native tissue is not a compromise. Functional outcomes of native tissue repair procedures are favorable, have a high rate of success, improve women's quality of life (QoL), and result in high rates of patient satisfaction. This subject requires further long-term, standardized prospective studies following the International Continence Society/International Urogynecologists Association guidelines for surgical outcomes report, with the focus on patient-centered functional outcomes.

A clinical study on the trocar-guided mesh repair system for pelvic organ prolapse surgery

Objective

To evaluate the complication and recurrence rates in patients undergoing trocar-guided mesh implant for pelvic organ prolapse (POP) treatment.

Methods

A retrospective study was performed based on the medical records of patients who had undergone mesh implant by one surgeon from May 2006 to August 2013 at the Presbyterian Medical Center in Korea. We evaluated perioperative complications such as bladder injury, mesh exposure, urinary symptoms, infections, and chronic pelvic pain. Recurrence was defined as a POP-quantification system stage ≥II or any symptomatic prolapse.

Results

Sixty-seven patients were evaluated, and the mean age of patients was 65.4±7.2 years. Stage ≥III POP-quantification Ba was noted in 61 patients (91%). Intraoperative complications included three cases of bladder injury (4.5%). The mean follow-up period was 44.1±7.9 months. Postoperative complications occurred in seven women (10.5%): four cases of urinary symptoms (6%), two cases of infections (3%), and one case of chronic pelvic pain (1.5%). Mesh exposure did not occur (0%). Prolapse recurrence was reported in five patients (7.5%).

Conclusion

Based on our operational result, the trocar-guided mesh implant seems to provide safe and effective outcomes.

Incidence and risk factors for mesh erosion after laparoscopic repair of pelvic organ prolapse by lateral suspension with mesh

INTRODUCTION AND HYPOTHESIS

The objective of our study was to estimate the incidence and identify the risk factors for mesh erosion after laparoscopic repair of pelvic organ prolapse (POP) by lateral suspension with mesh.

METHODS

We conducted a nested case-control study among 480 women who underwent POP repair by laparoscopic lateral suspension with mesh from January 2004 to October 2012. Cases (n = 18) were women who showed mesh erosion following the first intervention through December 2014. Controls (n = 133) were women randomly selected from the same cohort who did not have any erosion.

RESULTS

The risk of mesh erosion was 3.8 % with a mean follow-up of 82.3 months (range 28.2 - 130.6 months). The main risk factor was the use of a type 3 mesh (macroporous with either multifilamentous or microporous components) rather than a type 1 mesh (macroporous and monofilamentous; adjusted OR 13.0, 95 % CI 1.5 - 110.6; P = 0.02). Risk factors included smoking (adjusted OR 10.4, 95 % CI 2.3 - 46.5; P < 0.01) and posterior mesh placement (adjusted OR 5.1, 95 % CI 1.2 - 21.8 P = 0.03).

CONCLUSIONS

The risk of mesh erosion is low and may be further reduced by using the appropriate mesh material, and by identifying specific patient characteristics such as tobacco use. As conventional vaginal surgery is effective for the treatment of the posterior compartment, the use of posterior mesh during laparoscopic pelvic floor repair needs to be questioned.

Peritoneal closure over barbed suture to prevent adhesions: a randomized controlled trial in an animal model

STUDY OBJECTIVE

To compare adhesion formation and histological features of peritoneal closure and nonclosure over an intra-abdominally placed barbed suture.

DESIGN

Single-blind randomized controlled trial (Canadian Task Force Classification I).

SETTING

Certified animal research facility.

SUBJECTS

Eight nonpregnant rats.

INTERVENTIONS

Abdominal cavities were entered via midline incision. Left and right parietal peritoneal surfaces were incised 1.5 cm long separately and stitched with unidirectional barbed suture material (3/0 V-Loc). The parietal peritoneum was approximated over the barbed suture using polypropylene suture material (7/0 Prolene) to embed the barbed suture (peritonization) on one side, and left open on the other side. The side of the barbed suture to be peritonized was allocated at random. On the postoperative day 32, all rats were sacrificed, adhesion formations on each side were macroscopically scored, and histological features were evaluated microscopically.

MEASUREMENT AND MAIN RESULTS

The median adhesion score was 2.00 (range, 1-4) on operative fields. There was no statistically significant difference in median adhesion score between the peritonized and nonperitonized sides (1.5 vs 2, respectively; p = .13). Microscopically, there were no statistically significant differences in median acute and chronic inflammation scores between the peritonized and nonperitonized sides (p = .58 and p = .45, respectively), but a significantly higher median fibrosis score on the peritonized side (3 vs 1.5, respectively; p = .02).

CONCLUSION

Based on the results of the present study in a rat model, barbed suture material might be associated with adhesion formation when used intra-abdominally, and these adhesions could not be prevented by peritonization.

Sacral colpopexy: long-term mesh complications requiring reoperation(s)

INTRODUCTION AND HYPOTHESIS

Sacral colpopexy (SC) is a classic procedure used for the surgical treatment of pelvic organ prolapse. Although the procedure boasts excellent success rates, there are risks of complications and reoperation may be required. The purpose of this study was to evaluate the extent of complications following SC, requiring reoperation(s), and to describe the reoperations performed.

METHODS

A retrospective monocentric study of patients who were operated on following a mesh complication after SC was conducted, at Lille University Hospital, between January 2007 and January 2013. Information relating to medical and surgical history, SC surgical technique, type of complication, and reoperation techniques was gathered.

RESULTS

Twenty-seven patients required surgery for complications after SC. Nineteen patients were treated for vaginal mesh exposures (VME), four for intravesical mesh (including one with VME), one for ano-rectal dyschezia, one for spondylodiscitis with a VME, one for mesh infection, and one for vaginal fistula communicating with a collection in the ischio-coccygeal muscle. The median time between the initial SC and the first reoperation was 3.9 ± 5.7 years. The median operating time was 40 ± 95 min, and the length of hospital stay was 3.0 ± 3.0 days. Ten patients needed several interventions.

CONCLUSION

This case series provides a description of surgical interventions for complications related to sacral colpopexy. These complications may be serious and occur years after the initial surgery.

Mesh-related and intraoperative complications of pelvic organ prolapse repair

INTRODUCTION

To evaluate the rates of complications of pelvic organ prolapse repair and to determine their risk factors.

MATERIAL AND METHODS

The study included 677 patients operated for pelvic organ prolapse with trocar guided Prolift mesh. Patients were followed up within 1 and 3 months. A phone interview was conducted and patients with complaints were invited and evaluated in office settings.

RESULTS

Mean age was 60 years. For the phone interview, 86.5% of patients were available. Overall complication rates were 22.5% (152/677). Fifteen patients (2.2%) developed bleeding over 500 cc; pelvic hematomas - 5.5%; perineal hematomas - 2.5%; urethral injuries - 0.3%; bladder injury in 1.6%; rectal damage in 0.7% and ureteral trauma in 0.2%. MESH RELATED COMPLICATIONS INCLUDED: erosions in 4.8%; vaginal synechiae - 0.3%; protrusion of mesh into the bladder - 0.15%; vesicovaginal fistula with mesh protrusion - 0.3%; mesh shrinkage - 1%; dyspareunia and pain in 2.4% cases. Pelvic abscess was found in 0.6% including one case of lethal necrotizing fasciitis. The risk factors of complications were assessed via logistic regression analysis.

CONCLUSIONS

Younger age, less prominent prolapse, hematomas and concomitant hysterectomies are associated with higher risk of complications.

[Which prostheses to use in mesh sacrocolpopexy? Experimental and clinical study]

BACKGROUND

Sacrocolpopexy is the standard surgical treatment of genital prolapse of the upper vaginal wall. Nowadays, the laparotomy approach is progressively supplanted by the laparoscopic procedure for the same anatomical results. About sacrocolpopexy, to date it still remains details of the technique, which differ with surgical teams maintaining controversy. Among them, the choice of the meshes certainly creates debate.

OBJECTIVES

To state the basic physicochemical principles which are necessary for surgeons to select the most suitable prosthetic material to obtain the most beneficial anatomic and functional outcomes for patients.

MATERIAL AND METHODS

The concepts of prosthetic biocompatibility, strength, shrinkage, deformation and elasticity are discussed. They are illustrated by experimental animal references and also human clinical references.

RESULTS

Macroporous polypropylene and polyester prostheses (pore size>1 mm) are properly integrated. Collagen prosthetic coating improves tissue integration. Absorbable and nonabsorbable ultralight prostheses expose patients to a high risk of recurrence. Multifilament polyester wide pore-side prostheses have less retraction and are more flexible than monofilament polypropylene prostheses.

DISCUSSION AND CONCLUSION

The prosthetic cut-off weight below which the mesh does not offer any guarantee of strength is not precisely known. Moreover, the benefit of weight reduction is not proved. Currently, heavy weight multifilament polyester prostheses with wide pore size, more than 1mm, appear to be the most appropriate meshes for sacrocolpopexy without vaginal incision.

Apical prolapse

INTRODUCTION AND HYPOTHESIS

The aim was to review the safety and efficacy of pelvic organ prolapse surgery for vaginal apical prolapse.

METHODS

Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials (RCT) or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 case reports. The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. Grade A recommendation usually depends on consistent level 1 evidence. Grade B recommendation usually depends on consistent level 2 and or 3 studies, or "majority evidence" from RCTs. Grade C recommendation usually depends on level 4 studies or "majority evidence from level 2/3 studies or Delphi processed expert opinion. Grade D "no recommendation possible" would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi.

RESULTS

Abdominal sacral colpopexy (ASC) has a higher success rate than sacrospinous colpopexy with less SUI and postoperative dyspareunia for vault prolapse. ASC had greater morbidity including operating time, inpatient stay, slower return to activities of daily living and higher cost (grade A). ASC has the lowest inpatient costs compared with laparoscopic sacral colpopexy (LSC) and robotic sacral colpopexy (RSC). LSC has lower inpatient costs than RSC (grade B).In single RCTs the RSC had longer operating time than both ASC and LSC (grade B). In small trials objective outcomes appear similar although postoperative pain was greater in RSC. LSC is as effective as ASC with reduced blood loss and admission time (grade C). The data relating to operating time are conflicting. ASC performed with polypropylene mesh has superior outcomes to fascia lata (level I), porcine dermis and small intestine submucosa (level 3; grade B). In a single RCT, LSC had a superior objective and subjective success rate and lower reoperation rate compared with polypropylene transvaginal mesh for vault prolapse (grade B).Level 3 evidence suggests that vaginal uterosacral ligament suspension, McCall culdoplasty, iliococcygeus fixation and colpocleisis are relatively safe and effective interventions (grade C).

CONCLUSION

Sacral colpopexy is an effective procedure for vault prolapse and further data are required on the route of performance and efficacy of this surgery for uterine prolapse. Polypropylene mesh is the preferred graft at ASC. Vaginal procedures for vault prolapse are well described and are suitable alternatives for those not suitable for sacral colpopexy.

Complications of pelvic organ prolapse surgery and methods of prevention

INTRODUCTION AND HYPOTHESIS

The aim was to review complications associated with pelvic organ prolapse surgery.

METHODS

Every 4 years and as part of the Fifth International Collaboration on Incontinence we reviewed the English-language scientific literature after searching PubMed, Medline, Cochrane library and Cochrane database of systematic reviews, published up to January 2012. Publications were classified as level 1 evidence (randomised controlled trials [RCT] or systematic reviews), level 2 (poor quality RCT, prospective cohort studies), level 3 (case series or retrospective studies) and level 4 (case reports). The highest level of evidence was utilised by the committee to make evidence-based recommendations based upon the Oxford grading system. Grade A recommendation usually depends on consistent level 1 evidence. Grade B recommendation usually depends on consistent level 2 and/or 3 studies, or "majority evidence" from RCTs. Grade C recommendation usually depends on level 4 studies or "majority evidence from level 2/3 studies or Delphi processed expert opinion. Grade D "no recommendation possible" would be used where the evidence is inadequate or conflicting and when expert opinion is delivered without a formal analytical process, such as by Delphi.

RESULTS AND CONCLUSIONS

Transvaginal mesh has a higher re-operation rate than native tissue vaginal repairs (grade A). If a synthetic mesh is placed via the vaginal route, it is recommended that a macroporous polypropylene monofilament mesh should be used. At sacral colpopexy mesh should not be introduced or sutured via the vaginal route and silicone-coated polyester, porcine dermis, fascia lata and polytetrafluoroethylene meshes are not recommended as grafts. Hysterectomy should also be avoided (grade B). There is no evidence to recommend routine local or systemic oestrogen therapy before or after prolapse surgery using mesh. The first cases should be undertaken with the guidance of an experienced surgeon in the relevant technique (grade C). Expert opinion suggests that by whatever the surgical route pre-operative urinary tract infections are treated, smoking is ceased and antibiotic prophylaxis is undertaken. It is recommended that a non-absorbable synthetic mesh should not be inserted into the rectovaginal septum when a rectal injury occurs. The placement of a non-absorbable synthetic mesh into the vesicovaginal septum may be considered after a bladder injury has been repaired, if the repair is considered to be satisfactory. It is possible to perform a hysterectomy in association with the introduction of a non-absorbable synthetic mesh inserted vaginally, but this is not recommended routinely.
