Risk factors for vaginal mesh erosion after sacrocolpopexy in Korean women.

ABSTRACT: 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.

Project description:ObjectiveTo systematically review outcomes after mesh sacrocolpopexy compared with native tissue vaginal repairs in women with apical prolapse.Data sourcesWe searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov through June 4, 2012.Methods of study selectionFor anatomic and functional analyses, we included studies comparing mesh sacrocolpopexy to native tissue vaginal repairs with at least 6 months follow-up. The primary outcome was anatomic "success" after surgery. Secondary outcomes were reoperation and symptom outcomes. We included large case series and comparative studies with shorter follow-up to increase power for adverse event analyses.Tabulation, integration, and resultsEvidence quality was assessed with the Grades for Recommendation, Assessment, Development and Evaluation system. Meta-analyses were performed when at least three studies reported the same outcome. We included 13 comparative studies for anatomic success, reoperation, and symptom outcomes. Moderate-quality evidence supports improved anatomic outcomes after mesh sacrocolpopexy; very low-quality evidence shows no differences in reoperation between sacrocolpopexy and native tissue vaginal repairs. Evidence was insufficient regarding which procedures result in improved bladder or bowel symptoms. Low-quality evidence showed no differences in postoperative sexual function. Adverse event data were compiled and meta-analyzed from 79 studies. When including larger noncomparative studies, ileus or small bowel obstruction (2.7% compared with 0.2%, P<.01), mesh or suture complications (4.2% compared with 0.4%, P<.01), and thromboembolic phenomena (0.6% compared with 0.1%, P=.03) were more common after mesh sacrocolpopexy compared with native tissue vaginal repairs.ConclusionWhen anatomic durability is a priority, we suggest that mesh sacrocolpopexy may be the preferred surgical option. When minimizing adverse events or reoperation is the priority, there is no strong evidence supporting one approach over the other.

Project description:Abnormal vaginal microbiota (AVM), including bacterial vaginosis (BV), is caused by a microbiota imbalance. Nugent scoring is the gold standard for the laboratory diagnosis of BV; however, it is somewhat subjective to interpret, and challenging to distinguish bacteria. Hence, there is a need for improved technologies for the accurate diagnosis of AVM. To this end, next-generation sequencing (NGS) technology has been shown to yield comprehensive information on the pathophysiology of AVM. Hence, to evaluate the relationship between microbiota composition and the pathophysiology of AVM and its clinical significance, we characterized vaginal swab samples from 212 pregnant Korean women using both Nugent scoring and NGS analysis. Of these, the Nugent scoring identified 175 subjects (82.5%; 175/212) with normal flora (NF), 20 (9.4%; 20/212) with intermediate flora (IF), and 17 (8.0%; 17/212) with BV. NGS analysis followed by the characterization of vaginal microbiota composition, as represented by alpha and beta diversity, revealed the relative abundance of specific bacterial taxa at the genus and species level. Moreover, we identified all five predominant community state types (CSTs) along with three smaller CSTs. Analysis of the vaginal microbiota revealed the dominance of one or two Lactobacillus spp. in the NF group. Meanwhile, the IF and BV groups were dominated by the genera Gardnerella, Prevotella, and Atopobium. These two groups also showed higher alpha diversity than the NF group (p < 0.05). Principal coordinate analysis (PCoA) indicated that the NF group was significantly different from the AVM groups (p < 0.05), whereas no significant difference was observed between IF and BV groups (p = 0.25). Lastly, to investigate the characteristics of vaginal microbiota based on taxonomic composition, the IF and BV groups (AVM groups) were reclassified using the unweighted pair group method with arithmetic mean (UPGMA) clustering. Consequently, they were reclassified into BV1 (Lactobacillus iners-dominated), BV2-1 (Bifidobacterium breve-dominated), BV2-2 (Gardnerella vaginalis s1 or s2 and Atopobium vaginae-dominated), and BV3 [mixed population of G. vaginalis, L. iners, and other bacteria (p < 0.05)]. Collectively, these findings could serve to advance the current understanding regarding AVM pathophysiology.
