To treat pelvic organ prolapse (POP) and urinary incontinence, there is a novel “standardized” surgical technique, called cervicosacropexy (CESA) and vaginosacropexy (VASA), in which the USLs are replaced by polyvinylidene tapes. One of the main problems remains the fixation method, that should be stable, but also simple and quick to use. The current study evaluated the biomechanical differences between the cervical tape fixation with sutures (group 1), non-absorbable tacks (group 2) and absorbable tacks (group 3) in an in-vitro model.
A total of 28 trials, conducted in three groups, was performed on porcine, fresh cadaver uteri. All trials were performed until mesh, tissue or fixation device failure occurred. Primary endpoints were the biomechanical properties maximum load (N), displacement at failure (mm) and stiffness (N/mm). The failure mode was a secondary endpoint.
