Pelvic organ prolapse transvaginal repair by the Prolift system: evaluation of efficacy and complications after a 4.5 years follow up

Reoperation rate and outcomes following the placement of polypropylene mesh by the vaginal route for cystocele: very long-term follow-up

INTRODUCTION AND HYPOTHESIS

The aim was to evaluate the reoperation rate and outcomes in women who underwent transvaginal non-absorbable monofilament polypropylene mesh placement for the treatment of cystocele.

METHODS

The retrospective cohort study included 63 patients who underwent transvaginal surgery using a synthetic polypropylene mesh (Gynemesh™) for cystocele. Patients were evaluated using a clinical examination (POP-Q) and validated questionnaires (PGI-I, PFDI-20, PFIQ-7) at 18 years of follow-up (median 18 years [IQR 16-19]). Cumulative death rate was 13 out of 63 (20%) and rate of total loss to follow-up was 21 out of 50 (42%). Finally, among the 63 women who underwent surgery, 29 completed maximum follow-up and 21 underwent a clinical examination.

RESULTS

The cumulative reoperation rate was 35% (22 out of 63). Three patients were reoperated on because of recurrence of pelvic organ prolapse. Among the 63 patients initially operated, vaginal mesh exposure occurred in 16 (25%) during follow-up and 11 women (17%) needed a reintervention for vaginal mesh exposure. One patient was reoperated on for bladder mesh exposure. Among the 29 women who completed follow-up, the overall postoperative improvement rate was 93% after 18 years (PGI-I: 1-3). Mean overall satisfaction rate was 80 out of 100. Functional success rate was 76% (22 out of 29) and anatomical success rate was 62% (13 out of 21). The median score of the POP-DI-6 was 4.1 (IQR: 0-11) and the median score of the PFDI-20 was 30.7 (IQR: 13-60) in the 29 women who completed maximum follow-up.

CONCLUSION

At very long-term follow-up, the recurrence rate of cystocele following polypropylene mesh placement by the vaginal route remained low and the satisfaction rate was high. However, we found high cumulative reoperation and mesh exposure rates.

Long-term follow-up of patients treated by transvaginal mesh repair for anterior prolapse

OBJECTIVE

The aim of the study was to assess 5 years outcome of transvaginal single incision mesh surgery (SIMS) for anterior pelvic organ prolapse (POP).

STUDY DESIGN

This was a prospective study including all patients from January 2009 to December 2012 who underwent SIMS for symptomatic anterior prolapse stage ≥2, according to POP Quantification (POP-Q). Symptoms and quality of life were assessed using validated questionnaires: Pelvic Floor Distress Inventory (PFDI-20), Pelvic Floor Impact questionnaire (PFIQ-7), and Prolapse/ Incontinence Sexual Questionnaire (PISQ-12). Main outcome was subjective success (question 3 of PFDI-20 score = 0). Mesh-related complications, objective and functional outcomes were used as the secondary outcomes.

RESULTS

270 patients were included in the study. Median follow-up was 5,7 years [4,5-8,2]. Subjective success rate was 86,6% at 5 years. Objective success rate was 53,1% at 5 years. At 5 years, composite failure (subjective + objective) occurred for 17 patients (12%), 7 patients with direct recurrence and 10 with indirect recurrence. Re-treatment was performed in six patients (2,8%; 3 hysterectomies for apical recurrence and 3 posterior repairs for posterior recurrence). One case (0,4%) of asymptomatic mesh exposure occurred. The reoperation rate for mesh-related complications was 3,4%. At 5 years, de novo dyspareunia rate was 11,7%, 3,9% considered as mesh-related. A significant improvement was noted for symptoms and quality of life.

CONCLUSION

Five-year results demonstrate that vaginal mesh surgery provides a durable and safe repair of anterior compartment prolapse with a low rate of mesh-related complications and reoperations. Between the 2- and 5-year follow-up, patient satisfaction and associated improvements in prolapse-specific symptoms were sustained and minimal new morbidity occurred.

Synthetic Graft Augmentation in Vaginal Prolapse Surgery: Long-Term Objective and Subjective Outcomes

OBJECTIVE

To report long-term objectives and subjective outcomes in women who underwent prolapse surgery with a synthetic graft augmentation.

DESIGN

Retrospective analysis (Canadian Task Force classification II-3).

SETTING

University hospital in the southeastern United States.

PATIENTS

Women with symptomatic pelvic organ prolapse who underwent transvaginal graft augmentation using the Prolift mesh system between July 2006 and December 2008 for a minimum 5-year follow-up.

INTERVENTIONS

Subjects completed the Pelvic Floor Distress Inventory (PFDI-20), the Pelvic Floor Impact Questionnaire (PFIQ-7), the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ), and the Patient Satisfaction Questionnaire. Subjects also underwent postoperative physical examination with Pelvic Organ Prolapse Quantification (POP-Q) and vaginal pain/stricture assessment. Long-term postoperative findings were compared with preoperative baseline data.

MEASUREMENTS AND MAIN RESULTS

Of 208 eligible subjects, 70 completed the questionnaires only, and 48 of these 70 provided both postoperative examination and questionnaire data. The mean duration of follow-up was 7.0 ± 0.7 years (range, 5.8-8.1 years). POP-Q measurements of Ba (point B anterior), Bp (B posterior), C (cervix), GH (genital hiatus), PB (perineal body), and overall pelvic organ prolapse stage were significantly improved (all p < .001 except for PB, p = .006). PFIQ-7 (total, Urinary Impact Questionnaire, and Pelvic Organ Prolapse Impact Questionnaire) and PFDI-20 (total, Urinary Distress Inventory, and Pelvic Organ Prolapse Distress Inventory) scores significantly improved (all p < .001). No differences were noted in the colorectal-anal subscales (Colorectal-Anal Impact Questionnaire and Colorectal-Anal Distress Inventory) and PISQ scores at >5-year follow-up (all p > .05). Satisfaction rates were 15.7% for not at all, 35.7% for somewhat, and 48.6% for completely satisfied. Complications included graft exposure (n = 3; 6%) and dyspareunia (n = 25; 36%).

CONCLUSION

Women undergoing transvaginal prolapse surgery using a synthetic graft continue to have positive objective and subjective outcomes, leading to significantly improved quality of life at a minimum 5-year follow-up.

Long-term outcome after transvaginal mesh repair of pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

The aim of this study was to report long-term subjective and objective outcomes after the transvaginal mesh (TVM) procedure in long-term. Possible late-onset complications were of particular interest.

METHODS

This was a retrospective analysis of TVM performed using Prolift™ transvaginal mesh measuring subjective outcome using validated questionnaires. Objective outcome was assessed using the Pelvic Organ Prolapse Quantification (POP-Q) system using two definitions: POP-Q stage ≤ 1, and vaginal wall prolapse at or above the hymen or vaginal apex not descending below the upper third of the vagina. Complications were reported with the Prosthesis/Graft Complication Classification Code designed by the International Continence Society/International Urogynecological Association (ICS/IUGA).

RESULTS

Of 195 patients, 161 (82.6 %) participated this study after a median of 7 years. The scores in questionnaires evaluating urinary (UI) or anal incontinence and constipation or pelvic floor symptoms were low, indicating favorable surgical outcomes. Altogether, 80.1 % of patients were satisfied with the procedure. Anatomical cure was 56.4 % and 69.3 % depending on the definition used. Reoperation due to POP in any compartment was performed in 16.2 % of patients. Mesh exposure rate was 23 %, most of these being asymptomatic and of late onset.

CONCLUSIONS

Outcome of the TVM procedure was satisfactory. Anatomical cure was inferior to subjective cure. Mesh exposure rate was high; most exposures observed in the long-term were of late onset and were asymptomatic.

Pelvic reconstruction improves pelvic floor strength in pelvic organ prolapse patients

OBJECTIVE

To evaluate pelvic floor muscle strength after the modified pelvic reconstruction procedure for pelvic organ prolapse (POP).

MATERIALS AND METHODS

Patients were assigned to two groups consisting of 37 patients diagnosed with POP and undergoing modified pelvic reconstruction (reconstruction group), and 30 patients admitted to our hospital during the same period for other surgical indications (control group). Vaginal palpation of pelvic floor muscle strength was performed according to the modified Oxford grading system before operating on the two groups and again in the 3(rd) month following surgery for the reconstruction group. A comparative study was performed to evaluate the differences between the two groups and the improvement of pelvic floor muscle strength in the reconstruction group.

RESULTS

The pelvic floor muscle strength was significantly improved postoperatively when compared with preoperative results in the reconstruction group (t = -17.478, p < 0.001). However, pre- and postoperative muscle strength in the reconstruction group was significantly lower relative to the control group, respectively (χ(2) = 63.293, p < 0.001; χ(2) = 31.550, p < 0.001).

CONCLUSION

The modified pelvic reconstruction procedure could improve pelvic floor muscle strength in POP patients, which remains lower when compared with the normal population. Pelvic floor muscle strength should be included in the assessment of surgical outcomes in POP.

The improvement of pelvic floor muscle function in POP patients after the Prolift procedure: results from surface electromyography

INTRODUCTION AND HYPOTHESIS

Patients with pelvic organ prolapse (POP) have lower pelvic floor muscle (PFM) function. We hypothesized that pelvic reconstructive surgery could improve PFM function and strength.

METHODS

The controlled, nonrandomized study recruited 37 POP patients in the Prolift group and 30 non-POP patients in the control group. Two urogynecologists performed the Prolift procedure. One experienced physiotherapist who was blinded to the grouping conducted the surface electromyography (SEMG) evaluation using an intravaginal probe. The patient was considered objectively cured if she had stage 0 or I according to the Pelvic Organ Prolapse Quantification system (POP-Q) at the 3rd month postoperatively. Two types of contractions, namely maximum voluntary contraction (MVC) and short, fast contractions (SFC) in 6 s were performed at each SEMG measurement. The SEMG data were collected once in the control group on admission and twice in the Prolift group (on admission and at the 3rd month postoperatively). The t test, Mann-Whitney U test, and Wilcoxon test were used for statistical analysis.

RESULTS

A total of 36 POP patients were cured by the Prolift procedure. At the 3-month follow-up, the voltage and duration of MVC as well as the numbers and voltage of SFC increased significantly in the Prolift group. These variables were lower in POP patients compared to women without POP.

CONCLUSIONS

The restoration of pelvic anatomy may account for the improved PFM function with increased electrical activity in POP patients verified by SEMG. Evaluation of PFM function may be used as a clinical tool in the overall assessment of pelvic reconstructive surgeries.
