Evaluating the porcine dermis graft InteXen® in three-compartment transvaginal pelvic organ prolapse repair

Introduction and hypothesis

The aim was to assess the efficacy of three-compartment pelvic organ prolapse (POP) vaginal repair using the InteXen® biocompatible porcine dermal graft as compared to traditional colporrhaphy with sacrospinous ligament suspension.

Methods

Preoperative, operative, postoperative and follow-up data were collected retrospectively. Objective recurrence was defined as POP quantification ≥ stage II and subjective recurrence as a symptomatic bulge.

Results

Each group consisted of 63 patients. Surgery time was longer using InteXen® (72?±?24.5 vs 55?±?23.5 min, p?=?0.0002). Length of hospital stay (4.6?±?1.6 vs 4.9?±?2.1 days, p?=?0.34) as well as duration of follow-up (37.1 vs 35.7 months, p?=?0.45) were equivalent between the two groups. No case of mesh erosion or infection was noted. The objective (17% vs 8%, p?=?0.12) and subjective recurrence rates (13% vs 5%, p?=?0.12) between the two groups were not statistically different.

Conclusions

InteXen® was well tolerated but had similar efficacy to traditional colporrhaphy and sacrospinous ligament suspension.     

Perioperative experience of pelvic organ prolapse repair with the Prolift® and Elevate® vaginal mesh procedures

Introduction and hypothesis

We compared the operative and immediate postoperative experience of the trocar-based Prolift® and non-trocar-based Elevate® techniques used to repair vaginal prolapse.

Methods

A retrospective review of Prolift and Elevate repairs was performed. Baseline characteristics and operative and postoperative variables evaluated included compartment(s) repaired, adjacent organ injury, operative time (OT), change in hemoglobin (ΔH), pain score, narcotic use, length of stay (LOS), and short-term complications. Categorical variables were assessed as counts and percent frequency. Data were compared using chi-squared analysis and paired t test.

Results

Prolift (n?=?143) and Elevate (n?=?77) patients were similar in age (p?=?0.19). Concurrent hysterectomy was done in 22 (15.4 %) and 24 (31.2 %), respectively, and concurrent midurethral sling placed in 100 (70 %) and 50 (65 %), respectively. LOS (median, 25th,75th) after anterior/apical compartment repairs was shorter with Elevate, whether with (1.0; 1.0,1.5 vs. 2.0 days;1.0, 2.0; p?=?0.003) or without (2.0; 1.0, 2.0 vs. 2.0 days; 2.0, 3.0; p?=?0.024) hysterectomy, but no differences in OT, ΔH, pain score, or narcotic use occurred. Posterior compartment mean pain scores were lower with Prolift (3.6 ± 2.2 vs. 1.7 ± 1.5, p?=?0.035), and three-compartment-repair pain scores were lower with Elevate (0.6 ± 1.3 vs 2.5 ± 1.9; p?=?0.013). Three bladder injuries occurred with Prolift but none with Elevate.

Conclusions

Operative and postoperative experiences were similar between groups; however, Elevate anterior/apical repairs had shorter LOS, which might reflect more aggressive discharge planning. There were no bowel or major vascular injuries, and the Prolift trocar bladder injuries did not alter the surgical procedure.     

A retrospective comparison of two vaginal mesh kits in the management of anterior and apical vaginal prolapse: long-term results for apical fixation and quality of life

Introduction and hypothesis

To compare apical correction in stage ≥3 cystocele between two mesh kits.

Methods

This was a retrospective, nonrandomized study that compared two groups matched on anterior/apical POP-Q stage: 84 received Elevate Ant? single-incision mesh (Elevate Ant group) and 42 Perigee? transvaginal mesh (Perigee group). Follow-up at 1 and 2 years comprised objective (POP-Q) and subjective (PFDI-20, PFIQ-7, PISQ-12) assessments. The primary endpoint was objective success: 2-year apical POP-Q stage ≤1. Secondary endpoints were anterior POP-Q stage, subjective results and complications.

Results

Groups were comparable in terms of age (66.6 and 64.7 years, respectively; p?=?0.19), BMI (both 25.4 kg/m²; p?=?0.93), and history of hysterectomy (7.2 % and 14.3 %; p?=?0.21) or prolapse surgery (12 % and 14.3 %; p?=?0.72). Operative time was shorter in the Elevate Ant group (54.1 vs. 62.5 min; p?=?0.048), and the 2-year objective apical success rate was higher (92.9 % vs. 66.7 %; p?<?0.0001), with better point C correction (?5 vs. ?3.8; p?=?0.006). Function improved in both groups, with significantly better PFIQ-7 (p?=?0.03) and PFDI-20 (p?=?0.02) scores in the Elevate Ant group at 2 years. Vaginal exposure was not seen in the Elevate Ant group but occurred in two patients in the Perigee group (p?=?0.33). Factors associated with success were age >65 years (OR 7.16, 95 % CI 1.83?–?27.97) and treatment with Elevate Ant mesh (OR 10.16, 95 % CI 2.78?–?37.14). Postoperative stress urinary incontinence rate was greater with the Elevate Ant group (29.8 % and 16.7 %; p?=?0.11).

Conclusions

The use of the Elevate Ant mesh was associated with significantly better apical correction at 2 years. Function improved in both groups, but with a significantly better PFDI-20 score in the Elevate Ant group at 1 and 2 years. The postoperative stress urinary incontinence rate, however, tended to be greater in the Elevate Ant group. The results need confirming with longer follow-up of these cohorts and in randomized studies.

     

Evidence to justify retention of transvaginal mesh: comparison between laparoscopic sacral colpopexy and transvaginal Elevate™ mesh

Introduction and hypothesis

To determine if laparoscopic sacral colpopexy (LSC) offers better apical support with a lower exposure rate than transvaginal mesh surgery with Elevate?.

Methods

This was a retrospective cohort study comparing patients with apical prolapse (POP-Q point C ≥ ?1) who underwent Elevate? mesh repair (n = 146) with patients who underwent laparoscopic sacral colpopexy (n = 267).

Results

The sacral colpopexy group had a mean age of 59 years and a BMI of 25.7. Patients in the Elevate? group were older, with a mean age of 63 and a BMI of 26.3. Most of the patients of both groups presented with pelvic organ prolapse stage III (LSC 73.8% and Elevate? 87.0%) and their mean POP-Q point C were not significantly different (LSC 1.4 vs Elevate? 1.2 cm). Operative time was longer in the LSC group (113 vs 91 min, p < 0.001), but estimated blood loss was lower (75 cm³ vs 137 cm³, p < 0.001). No difference in mesh exposure rate could be found between the two groups at one year (Elevate? 0.7% vs LSC 2.6%, OR 0.26, 95% CI 0.03 to 2.10, p = 0.21). One-year objective cure rate, defined as no descent beyond the hymen, was 97.0% in the LSC group and 96.6% in the Elevate? group (p = .81). The overall recurrence (objective, subjective recurrence or reoperation) was also not different between the groups (LSC 4.5% vs Elevate 4.8%, p = 0.89).

Conclusion

Transvaginal Elevate? mesh delivers comparable apical support with a low exposure rate similar to that of laparoscopic sacral colpopexy.

     

The use of transvaginal synthetic mesh for anterior vaginal wall prolapse repair: a randomized controlled trial

Introduction and hypothesis

The aim of the study was to compare the efficacy and safety of transvaginal trocar-guided polypropylene mesh insertion with traditional colporrhaphy for treatment of anterior vaginal wall prolapse.

Methods

This is a randomized controlled trial in which women with advanced anterior vaginal wall prolapse, at least stage II with Ba?≥?+1 cm according to the Pelvic Organ Prolapse Quantification (POP-Q) classification, were randomly assigned to have either anterior colporrhaphy (n?=?39) or repair using trocar-guided transvaginal mesh (n?=?40). The primary outcome was objective cure rate of the anterior compartment (point Ba) assessed at the 12-month follow-up visit, with stages 0 and I defined as anatomical success. Secondary outcomes included quantification of other vaginal compartments (POP-Q points), comparison of quality of life by the prolapse quality of life (P-QOL) questionnaire, and complication rate between the groups after 1 year. Study power was fixed as 80 % with 5 % cutoff point (p?<?0.05) for statistical significance.

Results

The groups were similar regarding demographic and clinical preoperative parameters. Anatomical success rates for colporrhaphy and repair with mesh placement groups were 56.4 vs 82.5 % (95 % confidence interval 0.068–0.54), respectively, and the difference between the groups was statistically significant (p?=?0.018). Similar total complication rates were observed in both groups, with tape exposure observed in 5 % of the patients. There was a significant improvement in all P-QOL domains as a result of both procedures (p?<?0.001), but they were not distinct between groups (p?>?0.05).

Conclusions

Trocar-guided transvaginal synthetic mesh for advanced anterior POP repair is associated with a higher anatomical success rate for the anterior compartment compared with traditional colporrhaphy. Quality of life equally improved after both techniques. However, the trial failed to detect differences in P-QOL scores and complication rates between the groups.     

A randomized controlled trial comparing anatomical and functional outcome between vaginal colposuspension and transvaginal mesh

Introduction and hypothesis

Our aim was to compare anatomical and functional outcome between vaginal colposuspension and transvaginal mesh.

Methods

This was a prospective randomized controlled trial in a teaching hospital. Sixty-eight women with stage ≥3 anterior vaginal wall prolapse according to the Pelvic Organ Prolapse Quantification (POP-Q) system were assessed, randomized, and analyzed. Patients were randomized to anterior colporrhaphy with vaginal colposuspension (n?=?35) or transvaginal mesh (n?=?33). Primary outcome was objective cure rate of the anterior vaginal wall, defined as POP-Q ≤1 at 2 years. Secondary outcomes were functional results, quality-of-life (QoL) scores, mesh-related morbidity, and onset of urinary incontinence.

Results

The anatomical result for point Ba was significantly better at 2 years in the mesh group (?2.8 cm) than in the colposuspension group (?2.4 cm) (p?=?0.02). Concerning POP-Q stages, the anatomical success rate at 2 years was 84.4 % for colposuspension and 100 % for mesh (p?=?0.05). There were 5 anatomic recurrences (15.6 %) in the colposuspension group. The erosion rate was 6 % (n?=?2). No significant difference was noted regarding minor complications. Analysis of QoL questionnaires showed overall improvement in both groups, with no significant difference between them.

Conclusions

The vaginal colposuspension technique of anterior vaginal wall prolapse repair gave good anatomical and functional results at 2 years. Transobturator vaginal mesh gave better 2-year anatomical results than vaginal colposuspension, with overall improvement in QoL in both groups.     

Pelvic organ prolapse surgery with and without tension-free vaginal tape in women with occult or asymptomatic urodynamic stress incontinence: a randomised controlled trial

Introduction

We set out to determine if insertion of a retropubic tension-free vaginal tape (TVT) sling at the time of pelvic organ prolapse surgery improves continence outcomes in women with pre-operative occult stress incontinence (OSI) or asymptomatic urodynamic stress incontinence (USI).

Methods

We conducted a randomised controlled study of prolapse surgery with or without a TVT midurethral sling. The pre- and post-operative assessment at 6 months included history, physical examination and urodynamic testing. Quality of life (QOL) and treatment success was assessed with the UDI-6 SF, IIQ-7 SF and a numerical success score. The primary outcome was symptomatic stress urinary incontinence (SUI) requiring continence surgery (TVT) at 6 months. Long-term follow-up continued to a minimum of 24 months. Secondary outcomes were quality of life parameters.

Results

Eighty women received prolapse surgery alone (n?=?43) or prolapse surgery with concurrent TVT (n?=?37). Six months following prolapse surgery 3 out of 43 (7 %) patients in the no TVT group requested sling surgery compared with 0 out of 37 (0 %) in the TVT group (ARR 7 % [95 %CI: 3 to 19 %], p?=?0.11). After 24 months there was one further participant in the no TVT group who received a TVT for treatment of SUI compared with none in the TVT group (4 out of 43, 9.3 % versus 0 out of 37; ARR 9.3 % [95 %CI: ?1 to 22 %], p?=?0.06). Both groups showed improvement in QOL difference scores for within-group analysis, without difference between groups.

Conclusion

These results support a policy that routine insertion of a sling in women with OSI at the time of prolapse repair is questionable and should be subject to shared decision-making between clinician and patient.     

Post-reduction stress urinary incontinence rates in posterior versus anterior pelvic organ prolapse: a secondary analysis

Introduction/hypothesis

Stress incontinence with vaginal prolapse reduction is less common in women with posterior-predominant prolapse (rectocele) compared with those with anterior-predominant prolapse (cystocele).

Methods

This was a secondary analysis of a cohort of prospectively enrolled women with symptomatic pelvic organ prolapse at or beyond the hymen and prolapse-reduced stress urinary incontinence (SUI) testing. Subjects were included if they had anterior- or posterior-predominant prolapse with at least a 1 cm difference in pelvic organ prolapse quantification (POP-Q) points Ba and Bp (N?=?214). We evaluated the prevalence and risk factors of post-reduction SUI between the two groups.

Results

Comparing posterior (n?=?45) and anterior (n?=?169) prolapse groups, we identified similar rates of post-reduction SUI (posterior: 6/45, 13.3 %; anterior:18/169, 10.7 %; p?=?0.52) and SUI without reduction (posterior:4.4 %; anterior:11.2 %; p?=?0.26). Maximum prolapse size was slightly larger in anterior than in posterior patients (+3.1 vs +2.0 cm beyond the hymen, p?=?0.001), while a higher proportion of posterior subjects reported a prior hysterectomy (p?=?0.04). Among posterior subjects, lower maximum urethral closure pressure values (MUCP; p?=?0.02) were associated with post-reduction SUI. In contrast, among anterior-predominant prolapse, larger prolapse measured at POP-Q point Ba (p?=?0.003) and maximum POP-Q measurement (p?=?0.006) were each associated with higher rates of post-reduction SUI and were highly correlated with each other (R?=?0.90).

Conclusions

We observed similar rates of post-reduction SUI in women with anterior- and posterior-predominant pelvic organ prolapse. Factors affecting the anterior and posterior prolapse groups differed, suggesting different mechanisms of continence protection. These findings suggest that reduction incontinence testing for operative planning would be as relevant to posterior-predominant prolapses as it is to anterior prolapse.     

Comparison between trans-obturator trans-vaginal mesh and traditional anterior colporrhaphy in the treatment of anterior vaginal wall prolapse: results of a French RCT

Introduction and hypothesis

To compare the efficacy of a collagen-coated polypropylene mesh and anterior colporrhaphy in the treatment of stage 2 or more anterior vaginal wall prolapse.

Methods

Prospective, randomized, multicenter study conducted between April 2005 and December 2009. The principal endpoint was the recurrence rate of stage 2 or more anterior vaginal wall prolapse 12 months after surgery. Secondary endpoints consisted of functional results and mesh-related morbidity.

Results

One hundred and forty-seven patients were included, randomized and analyzed: 72 in the anterior colporrhaphy group and 75 in the mesh group. The anatomical success rate was significantly higher in the mesh group (89 %) than in the colporrhaphy group (64 %) (p?=?0.0006). Anatomical and functional recurrence was also less frequent in the mesh group (31.3 % vs 52.2 %, p?=?0.007). Two patients (2.8 %) were reoperated on in the colporrhaphy group for anterior vaginal wall prolapse recurrence. No significant difference was noted regarding minor complications. An erosion rate of 9.5 % was noted. De novo dyspareunia occurred in 1/14 patients in the colporrhaphy group and in 3/13 patients in the mesh group. An analysis of the quality of life questionnaires showed an overall improvement in both groups, with no statistical difference between them. Satisfaction rates were high in both groups (92 % in the colporrhaphy group and 96 % in the mesh group).

Conclusion

Trans-obturator Ugytex® mesh used to treat anterior vaginal wall prolapse gives better 1-year anatomical results than traditional anterior colporrhaphy, but with small a increase in morbidity in the mesh group.     

Primary versus recurrent prolapse surgery: differences in outcomes

Introduction and hypothesis

We set out to evaluate anatomical outcomes of recurrent vs. primary prolapse surgery, focusing on anterior colporrhaphy (AC).

Methods

A retrospective study was performed comparing patients who underwent AC for recurrent cystocele (group I) and a matched control group who underwent primary AC (group II).

Results

Thirty-one patients were included in each group. Median follow-up was 22 (5–55) months. Successful anterior vaginal support was obtained in 18/23 (78.2%) patients in group I and 17/21 (81%) patients in group II at 1 year (p?=?1.000) and in 9/21 (42.8%) patients in group I and in 15/21 (71.4%) patients in group II at 2-year follow-up (p?=?0.031).

Conclusions

Recurrent cystocele repair has a higher anatomic failure rate than primary repair at 2-year follow-up. Alternative surgical techniques that provide better long-term durability may be beneficial in repair of recurrent anterior wall prolapse.     

Transischioanal trans-sacrospinous ligament rectocele repair with polypropylene mesh: a prospective study with assessment of rectoanal function

Introduction and hypothesis

Despite good anatomical outcomes of pelvic organ prolapse (POP) repair by the vaginal route using synthetic mesh, complications limit their use. Clinical data are needed to generalize prolapse mesh repair by the vaginal route. The current study aims to evaluate midterm rectoanal function and clinical outcomes after transischioanal rectocele repair using a medium weight polypropylene mesh.

Methods

Between March 2003 and June 2004, 230 patients with stage II–IV anterior and/or posterior POP were included in a prospective multicenter study. The current study is based on the analysis of the 116 patients who underwent a rectocele repair via the infracoccygeal route through the sacrospinous ligament. Anatomical cure was defined when rectocele was at stage <II in the Pelvic Organ Prolapse Quantification (POP-Q) system. Postoperative functional results were evaluated using the self-administered Pelvic Floor Distress Inventory (PFDI) and the Pelvic Floor Impact Questionnaire (PFIQ).

Results

Of the 116 patients who received a posterior mesh with two arms via the infracoccygeal route through the sacrospinous ligament, midterm anatomical results were available for 78 women representing 67 % (78/116) of the operated patients. The mean follow-up was 36 (± 8.1) months. No rectal injury occurred during surgery. The objective success rate was 94.8 % and subjective (by patient satisfaction) was 93.23 %. Colorectal-Anal Impact (CRAI) and Colorectal-Anal Distress Inventory (CRADI) scores were both significantly decreased at midterm follow-up in comparison with baseline (42.7 at baseline vs 11.4 at 24- or 36-month follow-up, p?=?0.001 for CRAI, and 81.1 vs 34.4, p?<?0.001 for CRADI) highlighting the benefits of rectocele repair on colorectal-anal function.

Conclusions

Polypropylene mesh with two arms via the infracoccygeal route through the sacrospinous ligament has good anatomical results at midterm follow-up with significant improvement in symptoms and quality of life and is associated with few complications. Obstructive symptoms reported in cases of rectocele can be improved by transvaginal mesh repair.     

Changes in prolapse surgery trends relative to FDA notifications regarding vaginal mesh

Introduction and hypothesis

In 2008 and 2011, the US Food and Drug Administration (FDA) released notifications regarding vaginal mesh. In describing prolapse surgery trends over time, we predicted vaginal mesh use would decrease and native tissue repairs would increase.

Methods

Operative reports were reviewed for all prolapse repairs performed from 2008 to 2011 at our large regional hospital system. The number of each type of prolapse repair was determined per quarter year and expressed as a percentage of all repairs. Surgical trends were examined focusing on changes with respect to the release of two FDA notifications. We used linear regression to analyze surgical trends and chi-square for demographic comparisons.

Results

One thousand two hundred and eleven women underwent 1,385 prolapse procedures. Mean age was 64?±?12, and 70 % had stage III prolapse. Vaginal mesh procedures declined over time (p?=?0.001), comprising 27 % of repairs in early 2008, 15 % at the first FDA notification, 5 % by the second FDA notification, and 2 % at the end of 2011. The percentage of native tissue anterior/posterior repairs (p?<?0.001) and apical suspensions (p?=?0.007) increased, whereas colpocleisis remained constant (p?=?0.475). Despite an overall decrease in open sacral colpopexies (p?<?0.001), an initial increase was seen around the first FDA notification. We adopted laparoscopic/robotic techniques around this time, and the percentage of minimally invasive sacral colpopexies steadily increased thereafter (p?<?0.001). All sacral colpopexies combined as a group declined over time (p?=?0.011).

Conclusions

Surgical treatment of prolapse continues to evolve. Over a 4-year period encompassing two FDA notifications regarding vaginal mesh and the introduction of laparoscopic/robotic techniques, we performed fewer vaginal mesh procedures and more native tissue repairs and minimally invasive sacral colpopexies.     

Cystocele repair with single-incision,trocarless mesh system

Introduction and hypothesis

The use of mesh at the time of anterior vaginal wall repair reduced the risk of recurrent anterior vaginal wall prolapse. The aim of our video is to demonstrate our dissection technique focusing on the main anatomical landmarks in the pelvis and present an overall safer system to correct pelvic floor prolapse.

Methods

The video demonstrates correction of cystocele with the EndoFast Reliant? system (IBI Israel Biomedical Innovations, Caesarea Industrial Park South, Israel). The surgical technique is described.

Results

Twenty-nine patients were treated with the system. Mean follow-up was 10 (range, 6–30) months. At latest follow-up, favorable anatomical results were obtained for 26 of 29 patients (89.6 %); three patients presented stage 1 nonsymptomatic prolapse. Three cases (13 %) of de novo stress urinary incontinence (SUI) and two cases of de novo urgency (6.9 %) were diagnosed and treated. Postoperative voiding difficulties, dyspareunia, or pain were not observed.

Conclusion

The operation with the trocarless system was found to be safe, easy to learn and implement, and have the potential for reducing intra- and postoperative complications, with very satisfactory functional and anatomical results.     

Long-term outcomes of vaginal mesh versus native tissue repair for anterior vaginal wall prolapse

Introduction and hypothesis

To estimate the risk of repeat surgery for recurrent prolapse or mesh removal after vaginal mesh versus native tissue repair for anterior vaginal wall prolapse.

Methods

We utilized longitudinal, adjudicated, healthcare claims from 2005 to 2010 to identify women ≥18 years who underwent an anterior colporrhaphy (CPT 57420) with or without concurrent vaginal mesh (CPT 57267). The primary outcome was repeat surgery for anterior or apical prolapse or for mesh removal/revision; these outcomes were also analyzed separately. We utilized Kaplan–Meier curves to estimate the cumulative risk of each outcome after vaginal mesh versus native tissue repair. Cox proportional hazards models were used to estimate the hazard ratio (HR) for vaginal mesh versus native tissue repair, adjusted for age, concurrent hysterectomy, and concurrent or recent sling.

Results

We identified 27,809 anterior prolapse surgeries with 49,658 person-years of follow-up. Of those, 6,871 (24.7%) included vaginal mesh. The 5-year cumulative risk of any repeat surgery was significantly higher for vaginal mesh versus native tissue (15.2 % vs 9.8 %, p?<0.0001) with a 5-year risk of mesh revision/removal of 5.9%. The 5-year risk of surgery for recurrent prolapse was similar between vaginal mesh and native tissue groups (10.4 % vs 9.3 %, p?=?0.70. The results of the adjusted Cox model were similar (HR 0.93, 95%CI: 0.83, 1.05).

Conclusions

The use of mesh for anterior prolapse was associated with an increased risk of any repeat surgery, which was driven by surgery for mesh removal. Native tissue and vaginal mesh surgery had similar 5-year risks for surgery for recurrent prolapse.     

Prolapse repair using the Elevate? kit: prospective study on 70 patients

Introduction and hypothesis

The aim of this study was to examine the anatomical and functional results of prolapse repair by a vaginal approach using the Elevate kit.

Methods

This was a prospective study of 70 patients presenting with symptomatic urogenital prolapse. Twenty Elevate Anterior, 16 Posterior, and 34 Anterior and Posterior repair systems were placed. Perioperative and postoperative complications were assessed. The patients were interviewed at 2?months and 1?year post-surgery.

Results

Recurrences were recorded in 21 patients (31.3%) at the 1-year follow-up. However, at the 1-year follow-up, there were 14 cases (20.9%) of direct recurrence (two anterior, two posterior, and ten combined anterior and posterior) compared with seven cases (10.4%) of indirect recurrence. Of the 21 failures (stage ≥2), 13 were stage 2 with the leading edge above the hymen. None of the patients underwent revision surgery. The exposure rate was 4.5%. The anterior and posterior shrinkage rates were 68.7% and 31.9%, respectively. There were four cases of de novo dyspareunia. Patients reported a significant decrease in the impact of pelvic floor distress on the PFIQ-7 questionnaire, but an improvement on the PFDI-20. There was no improvement in sexual function (PISQ-12).

Conclusions

The Elevate? kit is associated with satisfactory functional results. However, the anatomical results require ongoing evaluation.     

A prospective study of transobturator tape as treatment for stress urinary incontinence after transvaginal mesh repair

Introduction and hypothesis

The transobturator suburethral sling is a common surgical treatment for stress urinary incontinence (SUI). In patients with incontinence after trocar-guided transvaginal mesh repair (Prolift?), data on outcome remain limited. In the present study, we hypothesized that transobturator tape in such cases is assumed to be as effective as surgery alone.

Methods

This was a prospective analysis of outcomes of transobturator slings in women who had undergone transvaginal mesh repair and in those who underwent sling surgery alone (controls). Objective cure was defined as the absence of urinary leakage during the stress test at filling cystometry and a negative cough test during pelvic examination. The success rates were evaluated 3–6 months postoperatively.

Results

One hundred women were recruited for the study. Compared to the control group, women after transvaginal mesh repair had a significantly lower objective success rate (62 vs 86 %, p?=?0.005) and poorer bladder neck mobility (0.5?±?0.8 vs 1.1?±?0.5 cm, p?=?0.001).

Conclusions

The transobturator sling has lower objective success rate in women after transvaginal mesh that may be due to decreased bladder neck mobility. Patients with post-mesh repair SUI who opt for sling surgery should be informed of these less satisfactory outcomes during preoperative counseling.     

Native tissue repair or transvaginal mesh for recurrent vaginal prolapse: what are the long-term outcomes?

Introduction and hypothesis

The objective of this study was to assess outcomes in native tissue (NT) and transvaginal mesh (TVM) repair in women with recurrent prolapse.

Methods

A retrospective two-group observational study of 237 women who underwent prolapse repair after failed NT repair in two tertiary hospitals. A primary outcome of “success” was defined using a composite outcome of no vaginal bulge symptoms, no anatomical recurrence in the same compartment beyond the hymen (0 cm on POPQ) and no surgical re-treatment for prolapse in the same compartment. Secondary outcomes assessed included re-operation for prolapse in the same compartment, dyspareunia and mesh-related complications.

Results

Of a total of 336 repairs, 196 were performed in the anterior compartment and 140 in the posterior compartment. Compared with the TVM groups, women undergoing repeat NT repair were more likely to experience anatomical recurrence (anterior 40.9 % vs 25 %, p?=?0.02, posterior 25.3 % vs 7.5 %, p?=?0.01), report vaginal bulge (anterior 34.1 % vs 12 %, p?<?0.01, posterior 24.1 % vs 7.5 %, p 0.02) and had a higher prolapse re-operation rate (anterior 23.9 % vs 7.4 %, p?<?0.01, posterior 19.5 % vs 7.5 %, p?=?0.08). Using composite outcomes, the success rate was higher with TVM repair in both compartments (anterior 34.2 % vs 13.6 %, p <0.01, posterior 56.6 % vs 23.0 %, p <0.01). Re-operations for mesh exposure were 9.3 % anteriorly and 15.1 % posteriorly. Although the number of women requiring a prolapse re-operation is lower in the TVM group, the overall re-operation rate was not significantly different when procedures to correct mesh complications were included.

Conclusions

Although the success rate is better with the use of TVM for recurrent prolapse, the total re-operation rates are similar when mesh complication-related surgeries are included.

     

Post-repair coaptation length and durability of mitral valve repair for posterior mitral valve prolapse

Objective

Chordal placement with no or minimal leaflet resection has been suggested as the preferred technique for mitral valve repair for posterior leaflet prolapse, because it creates a longer coaptation zone. However, whether or not a long coaptation zone improves the durability of mitral valve repairs remains unclear.

Methods

We reviewed 119 patients with chronic degenerative mitral regurgitation including posterior middle scallop prolapse who underwent mitral valve repair between June 2004 and July 2008. We divided them into two groups according to post-repair coaptation length ≥8 mm (group A) or <8 mm (group B). We assessed whether coaptation length is associated with recurrent mitral regurgitation at 1 year after surgery and increase in the regurgitant jet area over 1 year.

Results

The group A had a lower incidence of recurrent mitral regurgitation (4.7 vs 9.2 %, p = 0.30), smaller increase in mitral regurgitant jet area over 1 year (0.29 vs 0.40 cm², p = 0.43), and higher 5-year freedom from recurrent mitral regurgitation (85.6 vs 76.1 %, p = 0.76), although the differences were not statistically significant. The multivariate analysis showed that large coaptation length tends to be associated with decreased recurrent mitral regurgitation at 1 year (odds ratio 0.02, 95 % confidence interval 0.00–3.67, p = 0.14).

Conclusions

This study did not confirm the association between coaptation length and durability of mitral valve repair for posterior middle scallop prolapse. However, there was a trend towards decreased recurrent mitral regurgitation with larger coaptation length.     

Mesh retraction correlates with vaginal pain and overactive bladder symptoms after anterior vaginal mesh repair

Introduction and hypothesis

The aim of the present study was to determine possible correlations between mesh retraction after anterior vaginal mesh repair and de novo stress urinary incontinence (SUI), overactive bladder (OAB), and vaginal pain symptoms.

Methods

One hundred and three women with symptomatic prolapse of the anterior vaginal wall, stages 3 and 4 based on the Pelvic Organ Prolapse Quantification (POP-Q) system, underwent Prolift anterior? implantation. At a 6-month follow-up, the patients were interviewed for de novo SUI, OAB, and vaginal pain, and underwent an introital/transvaginal ultrasound examination to measure the mesh length in the midsagittal plane.

Results

Mesh retraction was significantly larger in a subgroup of patients (n?=?20; 19.4 %) presenting de novo OAB symptoms on the follow-up assessment compared with those without this complication (5.0 cm vs. 4.3 cm; p?<?0.05). Mesh retraction was also significantly larger in a subgroup of patients (n?=?23; 22.3 %) reporting postoperative vaginal pain compared with the women who did not report any postoperative vaginal pain (5.3 cm vs. 4.2 cm; p?<?0.01). A significant correlation was found between mesh retraction and the severity of vaginal pain (R?=?0.4, p?<?0.01). Mesh retraction did not differ between patients with de novo SUI symptoms and those without this complication.

Conclusions

Mesh retraction assessed on ultrasound examination after anterior vaginal mesh repair may correlate with de novo OAB symptoms and vaginal pain.
