| Popis: | Mesh repair of large hiatal hernias has increasingly gained popularity to reduce recurrence rates. Integration of iron particles into the polyvinylidene fluoride mesh-based material allows for magnetic resonance visualisation (MR). In a pilot prospective case series eight patients underwent surgical repair of hiatal hernias repair with pre-shaped meshes, which were fixated with fibrin glue. An MR investigation with a qualified protocol was performed on postoperative day four and 3 months postoperatively to evaluate the correct position of the mesh by assessing mesh appearance and demarcation. The total MR–visible mesh surface area of each implant was calculated and compared with the original physical mesh size to evaluate potential reduction of the functional mesh surfaces. We documented no mesh migrations or dislocations but we found a significant decrease of MR–visualised total mesh surface area after release of the pneumoperitoneum compared to the original mesh size (mean 78.9 vs 84 cm2; mean reduction of mesh area = 5.1 cm2, p |
