The aim of this study is to measure the mesh shrinkage and the visualization of the mesh with MRI scan at 1 month and 13 months after robot assisted preperitoneal hernia repair using the visible CICAT mesh (Dynamesh®).
The study will be conducted in the department of surgery in het AZ Maria Middelares, Ghent, Belgium. Dr. Filip Muysoms will personally select and operate all patients eligible for this study. He will inform all patients about the surgery and the follow-up with MRI scan thereafter. Dr. Beckers will perform all MRI examinations of the patients at 1 month and 13 months post-operatively and will be available for questions from the patient.
We want to show that with this type of mesh it is possible to visualize the preperitoneal placed mesh in a safe manner. Furthermore, the positioning of the mesh, mesh shrinkage or mesh shifting will be monitored with this technique. This provides long-term benefit and provides early treatment possibilities in case of post-operative complications related to the mesh position.
