different methods are described. Due to the low caseload of single surgeons, a sufficient comparison of these
techniques is almost impossible. Therefore, the repair must be concentrated in specialized centers to
increase the caseload, providing adequate expertise and allowing studies comparing different approaches
using a strictly standardized surgical technique. Nevertheless, the intraperitoneal sandwich technique seems
to be the most effective one. For some reasons outlined above, polyvinylidene fluoride-based meshes must
be used for the chimney and the sandwich technique.
