Abstract

Abdominal wall defects created in Sprague-Dawley rats were repaired with either polypropylene mesh (PPM), expanded polytetrafluoroethylene patch (PTFE) or polyglycolic acid mesh (PGA). Tensiometric studies of abdominal wall strength showed that PPM and PTFE provided a strong repair, but that the fibrous response induced by PGA was insufficient to produce a strong support for abdominal wall reconstruction. The size of the overlap at the interface between the abdominal wall fascia and prosthetic material has a greater effect on wound strength with expanded PTFE than with PPM. This is because of the different pattern of collagen infiltration into each material.

摘要

在斯普拉格-道利大鼠身上制造腹壁缺损，并用聚丙烯网（PPM）、膨体聚四氟乙烯补片（PTFE）或聚乙醇酸网（PGA）进行修复。腹壁强度的张力测量研究表明，PPM和PTFE能提供强力修复，但PGA诱导的纤维反应不足以对腹壁重建产生强力支撑。与PPM相比，膨体PTFE在腹壁筋膜与假体材料界面处的重叠尺寸对伤口强度的影响更大。这是因为胶原蛋白渗入每种材料的模式不同。
