ABSTRACT
PURPOSE:
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).METHODS:
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.RESULTS:
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 cm(2); mean reduction of mesh area = 5.1 cm(2), p < 0.001). At 3 months postoperatively, a further reduction of the mesh surface area could be observed (mean 78.5 vs 78.9 cm(2); mean reduction of mesh area = 0.4 cm(2), p < 0.037).CONCLUSION:
Detailed mesh depiction and accurate assessment of the surrounding anatomy could be successfully achieved in all cases. Fibrin glue seems to provide effective mesh fixation. In addition to a significant early postoperative decrease in effective mesh surface area a further reduction in size occurred within 3 months after implantation.Palabras clave
