Abstract

Purpose Many different surgical approaches have been established for the repair of a pelvic organ prolapse. Especially in laparoscopic surgery, it is important to generate easy surgical techniques with similar stability. This study shall simplify the choice of mesh by evaluating three polypropylene meshes regarding their biomechanical properties. Methods Biomechanical testing was performed in the porcine model. The meshes are fixated on porcine fresh cadaver cervices after subtotal hysterectomy. The apical part of the mesh is fixated with parallel screw clamps at the testing frame. Forty-one trials were performed overall, subdivided into four subgroups. The groups differ in mesh type and fixation method. Maximum load, displacement at failure and stiffness parameters were evaluated with an Instron -5565 (R) test frame. Results SERATEX (R) E11 PA (E11) showed the highest values for maximum load (199 +/- 29N), failure displacement (71 +/- 12 mm) and stiffness (3.93 +/- 0.59 N/mm). There was no significant difference in all three evaluated parameters between -SERATEX (R) B3 PA (B3) and -SERATEX (R) -SlimSling (R) with bilateral fixation (SSB). -SERATEX (R) -SlimSling (R) with unilateral fixation (SSU) had the lowest stiffness (0.91 +/- 0.19 N/mm) and maximum load (30 +/- 2 N) but no significant difference in displacement at failure. Conclusion All meshes achieved a good tensile strength, but the results of maximum load show that the E11 is superior to the other meshes. Through a bilateral fixation of -SERATEX (R) -SlimSling (R), a simple operating method is generated without a loss of stability.
