title: Risk factors for mesh erosion after transvaginal surgery using polypropylene (Atrium) or composite polypropylene/polyglactin 910 (Vypro II) mesh.
abstract: The objective of this study was to identify the risk factors associated with the occurrence of mesh erosion (ME) during the first 6 post-operative months in patients having undergone transvaginal repair of pelvic organ prolapse (POP) with Atrium or Vypro II mesh. We retrospectively reviewed the records of 198 consecutive patients who underwent vaginal reconstructive surgery reinforced either by Atrium or Vypro II mesh between February 1999 and July 2003. Univariable and multivariable logistic regression was performed to assess associations between measured covariates and ME. Fourteen patients [7.1%, 95% confidence interval (CI): 3.9-11.6] developed vaginal ME. We found that, in the Vypro II mesh patients, the surgeon experienced in the technique had less erosions than less experienced surgeons (2.9 vs 15.6%, p=0.02). There was no statistically significant difference between the monofilament polypropylene (Atrium) and the composite polypropylene/polyglactin 910 (Vypro II) mesh (7.2 vs 6.9%, p=0.41) when adjusted for surgeon experience and patient age. There was no association between mesh type (Atrium or Vypro II) and vaginal ME following transvaginal repair of POP. Surgeon experience and patient age were associated with ME.
